-FINALLY DYNOED, PRETTY HAPPY WITH IT- shitty track times inside
 

Well i finally made it back over to the twin cities and got tuned on tuesday. i ran into alot of problems last time i was down there and ended up just wasting time. finally got everything dialed in and it runs great! turned out it was a MAP sensor issue and once that was fixed everything was smooth sailing.

build up thread for the manifold and ---- https://www.homemadeturbo.com/forum/...?topic=92508.0

320 hp / 265 tq at 18 psi on a MUSTANG DYNO on E85.

setup is:
Y7/Z6
wiseco pistons .20 over
eagle rods
stock head gasket...
garret 57 trim 60/63
MSG motorsports manifold/downpipe/dumptube.... MSG is my roomates made up company
stock head revving to 8K

it rips! its definatly alot of fun, and traction owns me in 3rd. it was loving reving out and gettting more boost but it ended up lifting the head at 320 so we had to stop. im running 12 psi on the street now but im fixing to up it pretty soon here once i figure out the head lifting issue.

if i get a chance to make it back down to minneapolis i think im gonna change the head studs and gasket and try and up it a litte. heres a teaser pic, i have alot more of it on the dyno but i cant upload them at work. i got some of the car it self and ( wheels are now painted black as per your guys' advice) and a vid of it on the dyno.

DONT HATE ON THE PINK VC TO MUCH, ITS SUPPOSED TO BE AN ATTENTION GETTER


oh and you have to love that sick blue color the MSG manifold turned. guess it looks kinda different.

------- sweet man.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Should've done a co-op with OCZC, god rest his soul.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Nice.

I'm jealous (except the pink VC)

My 240k+ a6 is a bit haggard and slow.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

320/265 on a mustang is pretty kickass, Good Job

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

awesome numbers on a stang dyno. must be a lot of fun. that mani is pretty too

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

What head bolts are you using? Have you looked into arp head bolts?

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

look at all that room :D

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

i have ARP studs right now, i retorqued them last night to 65 ftlbs. and it still pushes coolant. i have an extra A6 block sitting here already bored/honed decked and i think ima send it away to be drilled for some 1/2" arp studs. eh winter project now

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Retorqued them last night to 85 ft lbs and you will be fine.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

If the head gasket is not set correctly/ smushed weird than more torquing isn't going to help.

Get some copper wire. Ring that bitch.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

85? really? sounds like kind of alot of torque. is that a common torque for them?

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

yeah if i can get a decent price for some sleeves i might sleeve and ring that A6 block i have.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

It is, going beyond the spec for the bolt is going to suck once thermal expansion happens.

Not to mention you have the possibility of warping the head if they don't budge.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

well any other suggestions for keeping the head from lifting then? i know ive heard of d series with much more power than this.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

JB weld.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

------- good numbers on a mustang dyno.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

how much did that garrett cost you? i have a ching chong turbo and it only made 240 Hp with 17 psi. meh, i guess you get what you pay for.

nice numbers!

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

610 brand new shipped to my door. yeah that china man scat metal will only make as much horsepower as .20 cents a day will pay for.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Ring the block, if you're still pushing coolant somethings up with the gasket.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

now i guess i havent heard much about ringing blocks other than ones ive just seen. can you do it on a block that isnt sleeved? and how hard is it to do? expensive?

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

There are no suggestions for preventing D-series head lift, because they don't lift. No D-series in the history of man has ever lifted it's headgasket so stop listening to e-faggots who have accomplished e-nothing in the real world. Also ignore faggots who say OEM rod bolts are remotely weak, that aftermarket FPRs are a tenth as good as 20 year old stock B-series ones, or that stock fuel lines are only good to 500 "but I wouldn't take my car there." I've run stock rod bolts to 9500, made 640 with slicks spining on the rollers off of stock fuel lines and OEM FPR, and generally disregarded most of what I read on forums because forums are like any large group of people; 95% of them are idiots.

You are vibrating the bores with detonation, causing the headgasket seal to breach. It is the sleeves that are moving as they are a lot weaker than the OEM headbolts. Back off on ignition timing and/or retard the cam a degree or two. Monitoring ECT during this process is handy, I've had cars make "the same" or sometimes better power when pulling timing, but the engine continues to run cooler, even losing heat mid-pull.

Frankly, 320 whp on a Mustang you are probably at the knock limit of pumpgas and that is why you are purging coolant. Water injection, better cam, some 110, congrats on putting together a manly setup now it's time to man up and take her to the next level. You will also have to replace your headgasket in the next 100-3000 miles as you've broken it's seal, and it will degrade.

Post up the dyno graphs, it's possible to tell by the shape of the graph if cam timing is an issue and if you need to retard it a little.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Pretty Sure he said he was runing E85.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

i love your uncontrolable knowledgeablities.
i would pull a little timing but A. i dont know how or how much timing to pull. i dont ---- with crome i let my tuner do that. and B. my tuner is 4 hours away from me and i cant just drive back and have him adjust it. ill get some more pics of the car and setup tonight and ill snap a pic of the graph as well.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

I'm pretty sure my reading comprehension is in the toilet.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

so are you still thinking the same thing then ? i would think the e85 would be able to handle quite a bit of timing before detonation

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Timing gun. Do it all the old fashion way take timing out at the dist. and the whole powerband. Weak rod bolts is something I dont know where it started the old man and I always laugh about all the stock rod b series all motor builds he did that got rapped into holy ---- land and never failed. It was always the valvesprings that make motors fall apart at high rpm.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

I have no E85 experience, but the stuff is supposed to be great even if the blend does change seasonally. You should be able to make more than 320 off it, but me having no practical experience with it I can't say.

Get those dyno graphs pls.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

this is somethign i have been thinking about, my base timing may be off a little. how bad will that ---- the whole game up?

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

well if you really advanced at the dist you have issues. Bust out the timing gun man that should of been done by the tuner and yourself before you even jumped on the dyno or even boosted.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Ive always done my d's arp's to 80lbs. Ive always done it at 40lbs in order, then 60, then 70, then 80. Im sure its overkill, but ---- it I haven had a problem. Replace your hg and then torque the ---- out of them.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

well bj setup is almost done he's putting my old kit on his rex and he says he's definitly running e85 so you'll have experience here shortly.lol.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Nice build. Which shop did you get it tuned at?

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

RS motor sports in the twin cities.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

E85 you should be able to make gobs of power on a D-series before they implode upon the failures of being a small bore, inefficient engine.

There are a couple tricks to keeping D-series from having coolant issues.

1) Headgasket and headstuds. Primarily over torquing the studs a good bit helps a great deal when using a quality stud(ARP). I forget the numbers but go on evans-tuning.com and Jeff posted his numbers that he uses with success. I believe they are similar to those posted below by ratcityrex.

2) Ignition timing. Don't run a lot. Simple as that. You are on E85 so you are not octane limited but you are going to have issues with D-series cylinder pressure in general because, D-series are small bore, inefficient engines. You could probably knock off 2-4* of timing, lose 5-10hp and not have cooling issues. Then raise the boost pressure another psi and knock the timing back another degree and make 20hp more. So in the end, you net +10hp and don't have cooling issues.

2) a. Run an EMS that actually controls timing well.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

Yeah with that much boost making 300hp your timing on a d should be getting close to or at single digit's. I tuned one the other day and it ended up at like 11 degrees at 16psi.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

but was that on e85? my freind just tuned on e85 also and i wanna say he was at 26* timing

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

No your right. It was just pump gas. Ive never messed with e85 so who knows.

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

26 holy ---- thats alot

Re: -FINALLY DYNOED, PRETTY HAPPY WITH IT-
 

E85 is race gas. 105-107 octane fuel is pretty hard to make ping at 300ish whp. You would have to run retardedly high ignition advance to get the engine to blow via detonation. The question is, did they actually need to run all of that advance or did they simple run all that advance because they could?
