Well tonite, me and ted put on a different turbo than the big T4 on the Trailerpark SBC 283 (refer to this thread)

Here are the turbos in the back of teds truck. Left-right 1st turbo is a .60/.63 Tbird turbo that we are borrowing from turbohf (dustin) Thanks again. Middle turbo is the T4 I took from a dumptruck. We already tried using this turbo and it didnt work out very well. It was just way to big, and only spooled 3psi. The next turbo is a CT26 Toyota supra Turbo.

Here is Ted doing a fine job with the coat hanger (welding) the homemade carb Bonnet.

We finally got the Mig welder working at PNK, so we layed a nice fatty bead on the T3 flange (over the T4 flange)

Shot of the HMT Bonnet, We had lots of little leaks at first but with about 9 coat hangers we got this sucker all welded up.

http://www.nw1320.com/hmt/ted/ted5.JPG

there were some small leaks, but thats ok. We call that "boost management"

You can see the Upper charge piping in this pic, once again all with the Coat hanger welding skills. and using mandrel 2.5in Pipe.

The plug off the back is for the blow off valve.

thanks to Craig @ tuner toyz for the great oil return flange, we also found a fitting in teds garage off a external oil relocation kit, worked perfect for the drain.

Shot of the Engine bay all done with the Charge piping.
Still needs an intercooler!

http://www.nw1320.com/hmt/ted/ted11.JPG

the charge piping was really hot

http://www.nw1320.com/hmt/ted/ted12.JPG

You can see the custom shield ted made (as he cut out his fenderliner) to guide the exhaust out of the engine bay.

Overall, This thing still needs alot of tuning. Our first test drive was pretty cool, It spools incredibly fast (the wastegate opens at 10psi) Fuel is the main concern right now since its using a stock fuel pump which will be later upgraded to a electronic bosch pump w/ regulator / adjustable fmu/ fuel return line. Ted also has a MSD 6BTM for spark control.

the 10psi of boost was over-riding the fuel pump pushing it back into the tank (since the base fuel pressure is 8psi)

More updates coming soon!

Jeff & Ted

Re:Completed SBC HMT (pics)
 

Looks nice, I like how its a bottom dollar turbo kit using the most expensive boost gauge around. how's that happen?

Re:Completed SBC HMT (pics)
 

yeh that looks nice
lookin forward to some more updates

Re:Completed SBC HMT (pics)
 

Just went down an put some supper unleaded in it an wow 2.19 a gallon DAMNNN..Anyway i got some fuel it in after i passed 2 cops an one was pulling out of the station as i was pulling in.Thought for sure i was gonna get pulled over due to no exhaust just off the turbo with a heat sheild to direct it to the fenderwell.No cops time to take her up the freeway on ramp for a run.Yes jeff it running out of fuel as long as i keept it below 8psi she kept pulling.Lil bit sluggish out of the hole but get rpms up above 2k an pulls up to 5500 then 2nd gear an tires dont hold her.Walks a lil an then away you go but fuel now on the low side so time to back out.Yes low budget turbo setup but i have been collecting parts for awhile now an thats one i aquired from a friend in a trade.Just thought it wasanother boost gauge .Will get the fuel system dialed in an hopefully get a few vids of it running.later all

Re:Completed SBC HMT (pics)
 

Good job on the install, needs some work but you are making nice progress.

You don't really see a stock snorkel intake turned into a boost friendly bonnet that often, hope it works out for you. Often times people just fabricate their own and ride with it, there are also many after market bonnets avail.

For the problem you are having feeding the beast gas at full boost, have you looked into boost referencing the stock fuel pump? Unless you are planning on some insane boost levels, the stock should hold for moderate usage.. all ya need is JB Weld.

Check this site out for some info on boost referencing, might save you from buying an expensive fuel pump/regulator:

http://www.toohighpsi.com/BudgetTT/tthowto.htm

Also what are you doing about enriching that holly carb at high boost/rpm? Replace the secondaries or what? If you have spare parts from a NOS fogger you could always run fuel in it using a Hobbs switch to turn on under boost (or just a plain ole fuel injector would work). I know you have a lot of fuel management work ahead of you (hope to see an EGT or 02 sensors too) but keep us posted, let me know if I can help

yeah it's really late, hope my post makes sense

Re:Completed SBC HMT (pics)
 

I like it !!! Time to start towing stuff ( LIKE HOUSES ). You should look into a Volvo intercooler, if you live near by me, I'd say "pick it up and its free" but its too big of a hassle to ship...

I thought more was involved in turboing a carb, but guess not... I'd like to do it one day ( 351 powered fox body stang with HMT ).

Re:Completed SBC HMT (pics)
 

yo man sweet build up after im done grenadeing my chevy 4 cyl turbo i wanna drop a 8 in the little s-10 that could with boost,and ply around 2 ;D.

Re:Completed SBC HMT (pics)
 

Yes i would love to pick up that intercooler.Road trip time ....lol
In reference to the web site been there thanks for the info
I beleive the fuel pump needs to be change to an electric because i need 5psi per pound boost which at this point is 50 psi plus 8 for normal running psi.I have been on the yahoo blowthrough group for a year an have followed all there build up an read many articles they have on carb modifications.I cut the choke horn off an jb welded the linkage hole an drilled the (pvcr)power valve orfice to 3/32.
Drilled the air cleaner stud to 3/8 instead of 5/16.An the bonnet is yes a factory air cleaner welded shut with the factory extension housing on it from a van/truck Pull apart special 8.00.... Carb bonnet 150 bones ill spend the savings on a better fuel system.Got the fuel system handled just need to do the installation.All i can say is that the trailer park 283 doesnt smoke an at 7.1 compression i think it can handle 15 psi ;D.Time for a boost controller.

Re:Completed SBC HMT (pics)
 

:o Love the bonnet and coathanger technique. Mad props.

Re:Completed SBC HMT (pics)
 

Cadracer,

good to see you already know more then I do and have been planning this thing for a year+ now.

if I was going base budget style I think I would run the boost referenced high flow mechanical fuel pump with regulator, but you got your system going on so it's all good. Time will tell if I end up boosting a sbc, probably not my current one - reliability and low end is the key(nothing like breaking down in the middle of the woods miles away from home that requires 4 wheel drive).

If you factory snorkel holds well for ya, keep it.. I might be able to find some info on fabbing a decent looking one if you are insterested. Keep up the good work and keep us posted.

Re:Completed SBC HMT (pics)
 

**big 2 thumbs up to you and Ted**

Re:Completed SBC HMT (pics)
 

Tonite we put on the Mitsu 3000GT Blow off valve, and put in a FP gauge, and a bigger fuel pump. But it didnt seem to help, so Electric pump is going on next.

It was hitting 15psi tonite too, lol ::)

Re:Completed SBC HMT (pics)
 

:D Know that we got the Home made bonnet secured a supposedly a better fuel pump we tried it out.15psi :o
an no idea what rpm we were at the autometer tach inop DOA.
Jeff was waiting for v-tech to kick in lol Thats all she will spin she wont spin no more.....The trailer park 283 used a lil oil today but all seems well.Boost referenced a holley race pump an took the signal right off the wastegate actuator hose an well thats when boost spiked at 16psi-seamed to pull really good but with no intercooler an fuel pressure issue it goes away when it hits second gear.needs definite fine tuning...The carb bonnet is working quite well now that the blow off valve is installed an it spools 10lbs boost quickly. I think the next update we need to take some video of some boost happening.Sounds really good when she ripps through first an partiall of second dumping straight off the turbo.Getting close to dyno time just to see what she got for power figures.Will keep you all posted...Thanks again Jeff

Re:Completed SBC HMT (pics)
 

You boost referenced and still getting push back.. if only I had one of my own sbc's turbo'd I could tell you more..

how are the plugs looking, pulled them yet? You said you enriched the secondaries.. right, but since boost is kickin pretty well I'm sure you're still running lean at higher rpms??

How did you set timing on that thing?

I'm really anxious to see how the finish product comes out.

I'm sure nobody thinks anything of the exhaust dump out the fenderwell, they say to themselves "it's an old truck, I'm sure it has it's share of normal problems.. like the heads have been eaten away by rust :P

Re:Completed SBC HMT (pics)
 

Well, I think the 1/8th NPT fitting was a bit to large, the hole got tapped out to big inside of the actual pump and was blowing air directly into the crankcase.. :-X

Oh well, switching to an Electric pump, regulator and FMU, so we can get this ------- thing dialed in. Plus we need to get some sort of a downpipe on this thing so we can weld in a o2 Bung and put a Wideband o2 sensor on it to see whats really going on.

The plugs are a little on the lean side.

Jeff

Re:Completed SBC HMT (pics)
 

Time for an update on the trailer park 283.Got the down pipe made an installed an an o2 bung welded in.Sounds pretty good but need to get exhaust out of the engine bay so i had a local exhaust shop weld up 3 in straight pipe an dump it out into a 4in madrel bend in front of the drivers rear wheel.Jeff installed his wide band o2 an in the process he melted my ignigtion coil.My fault though cuz i had bare tach wire under dash an it touched my braided fuel pressure isolator line.Got it fixed that night an fuel was good till secondaries kicked in then pig rich.Looked like a diesel exhaust solid black smoke.Jetting was 68 primary an 78 secondary with a 6.5pv,Thought i needed more fuel before wide band installed so i jetted it up 78primary an 85 secondary with 4.5 pv.Way to much so back to origanal settings.Ran great until secondaries opened up.Dynoed it next day cause it ran good but rich on upper rpm. Half throttle an it still pulled 208 an 293 ft lbs torque all before 3500 rpms.Lots more lerkinging below the surface just need to get it out.This 283 has rpm potential of 7000 if fuel correct.Dropped rear jets to 67 an tried an an wow it ripped no chugging.Need wide band an some more fine tuning.Cant do to much tuning now cause its raining here an tires dont hook no more.Time for the mickey thompson drag radials an see how she goes no.Videos will come next look for them in near future.

Re:Completed SBC HMT (pics)
 

Awesome man...yeah Vid's would be grate

Re:Completed SBC HMT (pics)
 

Ya, the Trailerpark SBC needs some carb work big time and she will rip nicely. Plus its in need of a turbo here pretty quick too. 208whp isnt bad for a 1/2 throttle pull on the dyno. At WOT it made 160ish whp lol.. It sounds very cool.

Pics of the dyno and more HMT ---- coming soon ;D

Re:Completed SBC HMT (pics)
 

How does that custom wastegate flange on the T4 work? ;)

Re:Completed SBC HMT (pics)
 

function wise it bolted on an sealed good but i couldnt produce enough boost for it to have to work.Thats what happens when u use a turbo that works off of a 933ci engine an u stick it on a 283 ci engine not enough exhaust flow.....

Re:Completed SBC HMT (pics)
 

Time for update on the v8 turbo got the intercooler piped in an btm installed an carb dial in almost perfect.
Dyno results made 234 hp an 360 ftlbs torque. Its a lil less than what i thought but i guess 7.1 comp ratio an only 283 ci plays a part in it.Does all this from 1800 to 3100 rpms at 11 psi an falling of to 8 psi of boost.The wideband 02 was almost prefect from idle to full boost at 5000. Time for more cubes.Gonna 1/8 drag it tommorrow to get a real idea what it does on the street.Ill Keep you all updated

Re:Completed SBC HMT (pics)
 

am i the only one who cant see any pics?

Re:Completed SBC HMT (pics)
 

there hosted on draglab nad its down.

Re:Completed SBC HMT (pics)
 

7.1:1 compression ratio? Install EFI and wind the boost to about 35psi ;D

Re:Completed SBC HMT (pics)
 

;D well efi would cost another 700 to 1000 dollars to do it right.I have the carbed dial in just as good as efi an i have a btm so i can back off timing with boost.Uping the compression to 9.1 got some aluminum heads gonna put on there an gonna swap out the sloppy/oil leaking t3 for a god tight t4.Tuned the carb with the wide band.goes lean at idle due to carb is not four coener idle.Got new carb just need to swap it on an i will put the new turbo an heads on at that time....

Re:Completed SBC HMT (pics)
 

Can't wait to see it.. since all I see are those purty red X's ;)

Re:Completed SBC HMT (pics)
 

---- man, you got a revamp coming real soon. I can't wait to see it (inspiration all over again).

Re:Completed SBC HMT (pics)
 

ted your carb is not lean at idle, it sits just as normal as my honda does ???

More pics coming soon

Re:Completed SBC HMT (pics)
 

So i guess i need have my own web hosting cuz i dont see my pics here anymore.Think i am gonna swap out the 76cc heads for the aluminum 58cc i got this weekend.I need more power out of the hole an the 7.1 compression just aint doing it.Think 9.5 will be good enough with the solid roller cam to wake it up the motor an then boost it a lil.....I got some good video but no hosting site so im looking to do that very soon.

Re:Completed SBC HMT (pics)
 

I know how that feels. My 267 had 8.3 Cr and it wasn't doing any thing untill I hit 2000 Rpm. First gear to 65 Mph
Second gear (if it shifted) dunno...road to short. And then NO BRAKES..... Close encounters of the worst kind.
Let's see what my 305 roller will do if i can find a car to fit it in. I'll be sure to check the brakes properly before i testdrive again.

Pj.

Re:Completed SBC HMT (pics)
 

:o Today i tore apart an cleaned up a 650 vacumm secondary card for a buddy who is in the process of tt a 351w in his 68 mustang.One of the people while at his party ,decided to dumped dirt an gravel down the throat of it.Anyway i needed a running engine with a square bore intake so i removed the 650dp from the turbo 283 an installed it an fired it up an no leakes so i wanted go try out the 283 on 7.1 comp.
Damn the thing wouldnt rev past 4000 held my foot to the floor she finnally hit 4500 LOL.No wonder i dont have no low end power till turbo boost at 2k.So i am now gonna swap out the big roller for a small solid lifter cam with a set of 305 heads boosting comp to 9.0 this should help.Just really showed how these turbos add power to these otherwise low power engines.
I like it I love it I want more of it
Let you all know how it does this week with the head an cam change.Gonna see if i can get a 1st place trophy this fri at the 1/8th mile drags.Got 3rd place last time out 2 weeks ago.Night all

Re:Completed SBC HMT (pics)
 

I wish I could run 305 heads, bring my compression up to 11.x:1 (after decking of the heads and what not)

The 305 heads just can't flow like the 350 so they are just hanging out in the laundry room. I sandblasted the hell out of one of them, it's ready for the leakdown test.

You said you got some aluminum heads?

Re:Completed SBC HMT (pics)
 

;D yup got some aluminum heads of a 350 vette.Got the d port exhaust an screw in studs an guide plates.ready for a roller cam.Hmm i got some 305 heads of a newer engine an the ports are better than the stock 350 heads i have.There sitting here waiting for a motor.My garage is like chevy motor central.Got 4 engine stands with engines on them an also got a home depo flat cart full of engines sitting on there butts waiting to be used.Why u decking heads?305 castings 58cc an 350 have 76cc brings a 8.5 to 9.7 an they flow just fine up to 5k with mild pocket porting.Email me ill hook you up.

Re:Completed SBC HMT (pics)
 

man i forget the numbers right off the top of my head. All I know is that if I swap down to 305 heads then my compression goes crazy.. this is counting my existing motor already being shaved, the 305 heads I have needing a shave and whatever else I have with the setup.

I'll let you know what parts I need when I get back to arkansas.

Re:Completed SBC HMT (pics)
 

??? Today removed the t3 an ground of the t3 flange welds.Damn i got some good penetration wasnt gonna come fall off.Gonna install the t4 an swap out the cam an heads.Got to get the last bit out of the trailer park before it gets mothballed.Got t-400 trans for the caddy now gonna have to take the heads an block to our hmt fabricator an have a dual quad manifold made.Got this twin turbo twin bonnets in my head.Damn its gonna look awesome.LOL so ill have to get some more use out of sbc for now.Wanna get at least 1 run through the 1/4 see what it will do.Its just a long way to drive damn it......What if i break????Look for some pics soon on the setup

Re:Completed SBC HMT (pics)
 

dude i can't wait for that crazy new setup.. I'll help you wherever I can dude since I know I'm going to be knocking down your PM box eventually for your expertise.

Re:Completed SBC HMT (pics)
 

Ever since the other day i have have had these images of dual bonnets aimed oppisite ways on a custom killer manifold an twin turbos.Goona look outrages an i am sure gonna be a lil touchy on the tune.But im up for it all.Wish i could take a picture whats in my mind....

Re:Completed SBC HMT (pics)
 

there is always ms paint man, try and draw that ---- out... I have a good idea of where you are going in my head.

Don't forget about all the fuel injectors and bosses that will need to go into the runner ;)
