New custom home made twin charged kit....
 

Well it was a LONG!!!! time in the making and or planning... to many numbers and charts and more numbers and 100's of calculations later and i have a sucsessfull atempt at Twin charging my 2.4L.... It started out as the GM supercharger kit and drove that for about 10months, had some fun with it... pushed it to its limits, then saw a Twin charged SS cobalt at the Sema Show... and since then i started this project... Every thing in conjunction with the turbo is all custom made... only things bought from a shop were the Turbo (obviously) and intercooler... every thing else was fabed up by me or my old man in our garage... now this wasnt the most chanaling install we have done on a car but it did take a fair amount of time
I have had this on the road now for about 1000kms.... but i am still running on my GM s/c'er computer reflash and 310cc injectors... so i can only do %50 throttle max... and have to keep an eye on my boost/knock gauge.... and i can only run her up to about 5-6psi before i can feel the injectors maxing out and knock going a bit high.... so i have not been able to rip on her yet but the amount i can feel is VERY NICE!!! the one time i did his about 10-12psi of boost... i hit it at around 1600rpm.... and thats with the 3.0" supercharger pulley helping spool it... which is 2 sizes bigger then what came stock with the s/c'er.... So i am now in the proses work working with the By pass to have it go as normal so i build boost instantly like normal with the s/c'er but have it open back up after a set boost level so that i dont get any more heat from the s/c'er and then it would be all turbo for the top end.... as the air would be passing the rotors on the s/c'er and just acting like a normal intake manifold... (a guy with a civic did this so he is helping me out with it)... But as far as tuning goes im going once my intercooler is in and the plan is just to tune my stock computer and sell the GReddy eManage unit.... and then run 10psi into the engine as the Turbo waste gate is reading whats going into the engine (so after the s/c'er) so it is constantly changing at the turbo to maintain the 10psi into the engine....

... any way the specs are:
Engine:
-62mm throttle body
-Custom made Log style manifold
-RK sport Upper and Lower engine mounts
-Custom 2.5" down pipe
-Custom 3" down exhaust with electric cut out just after the Down pipe
-GM supercharger (Eaton)
-Custom made Intake
-SMC alcohol injection
-Spec Stage 3 clutch
-Spec Aluminum Flywheel
-Quaife Limited Slip differential
-Garrett T3/TO4E 60 trim turbo
-Tial 38mm wastegate
-HKS SSQ blow of valve
- 31"x6"x3" front mount intercooler
-custom turbo manifold/charge pipes
-440cc injectors
-GReddy eManage (maybe be up for sale soon)

now on to the pictures....

Before: supercharger only

Re: New custom home made twin charged kit....
 

aren't you gonna tell us how it runs/drives ???

Re: New custom home made twin charged kit....
 

Look like good fab work, how does it hook up on the street? I couldn't imagine a twin charged FWD drive car could keep traction without slicks....Also, how long does it take to spool that turbo?

Re: New custom home made twin charged kit....
 

ahh yes sorry... ill edit it...

Re: New custom home made twin charged kit....
 

i think we all want to know how its running... if at all.. sick setup

Re: New custom home made twin charged kit....
 

yep its running... only i rip on it hard yet since im still on the GM s/c'er re-flash with 310cc injectors which max out around 220-230whp... and i can feel them maxing out around 5-6psi of boost... so once i get my 440cc injectors in and tuned im good for 10psi which from other guys with just turbo's on their 2.4L's are pushing around 280whp.... which isnt bad for a start... but you know its only going up from there... already ordering Forged rods, forged crank, 9:1 pistons ect.... and going to boost it to 20-22psi... which should be good for 400whp.... if not the boost is going up untill i hit the 400hp :D but from numbers and other dynos... 22psi should give me the 400hp i want...

Re: New custom home made twin charged kit....
 

Wow that is pretty impressive.Great work you and the old man did.Get some bigger injectors and put it on on dyno I owuld love to see the curve.Get some video too.

Re: New custom home made twin charged kit....
 

looks solid but 10 psi wont get you 280whp especially on that crusty 2.4 ld9

Re: New custom home made twin charged kit....
 

Thanks man... even my old man thinks this has got balls now and his daily driver is a 400hp Trans am ahah and his toys are 87 GNX and a 06 Lingenfelter 800hp Twin turbo Corvette... the new intercooler arived today so tuning should be soon...

well that is a guess obviously... but my guess is probably close... as i am maxing out the 310cc injectors at 5psi of boost and they max out ar 220-230whp... also i am going off of every one else i know who has a turbo 2.4L at different boost levels but 280whp isnt going to be far off from what every one else is dynoing at.... and if 5psi is giving me say 220whp.... from 130whp stock im sure 5psi more is going to get me pretty damn close to the 280whp mark....

Re: New custom home made twin charged kit....
 

eh, i dunno. we built peteys cavy with the 2.4 ---- and at 10 psi it wasnt 280whp ill tell you that,. and his kit was one of the most solid kits ive seen on a cavalier.

we had that ---- minty. i woulda guessed 240whp tops.

Re: New custom home made twin charged kit....
 

did you get it dynoed? cuz when i just had the supercharger my buddy had the exact same setup... i had a few more things but he dynoed at 205whp @ 5psi on the GM supercharger with no cooling units... and Superchargers make less power per PSI.... and when i was running just the supercharger i never felt my injectors max out and i got up to 9psi on the supercharger with alcohol injection

Now with the turbo added in i can actually feel the injectors maxing out at around 5-6psi into the engine.... and with all the calculations i have done... and double checked on the RC web site... for the 310cc injectors i have in... they will max out around 220-230whp... so that means at 5-6psi i am already hitting 220hp... so i am pretty sure 5psi more will make more then 10-20hp.... i will try to find some dyno sheets to put up on here though... so its not all just talk... cuz i know its hard to believe some people some times...

Re: New custom home made twin charged kit....
 

That's pretty scientific - I mean the way you tell when your injectors are maxxed out. Good for the engine too.

Re: New custom home made twin charged kit....
 

Makes sense to me, when the injectors are maxed it will begin to lean out, you will feel a hesitation, almost like a soft-cut rev limiter. Same feeling you get with a bad fuel pump.

Re: New custom home made twin charged kit....
 

its not like i max it out constantly... i felt it once maybe twice and backed off... i dont drive the ---- out of this right now... so its not going up there... just im constantly watching my boost and knock gauge... but the intercooler arived so i can start putting that on and my injectors in and get it tuned soon


yep same thing... same thing we had problems with in the gnx... so we had to go to 72lbs injectors and WOW did it ever make a difference... so i cant wait to get my new injectors in and actually test the car out :D

Re: New custom home made twin charged kit....
 

yummy twin charge :6

Re: New custom home made twin charged kit....
 

lol thank you

Re: New custom home made twin charged kit....
 

Am I understanding correctly that you have more boost at a lower rpm with the s/c spinning slower since you installed the turbo? Larger pully = less s/c rpm? Please clarify. I'd like that down low power for auto-x.

Did you read the twincharge article and test that Turbo mag did on the mr6? The s/c was set for 5ish psi but was left in the airflow with the turbo blowing into it. It still contributed to the power. Something along the lines of it doesn't car what the pressure of the air coming into is, it just boosts it up 5 psi if that's what it's pullied to. (I know that's a very vague description). Anyway excellent job.

Re: New custom home made twin charged kit....
 

holy ---- i just read a lot and never got any dyno numbers

u just waisted 4 min of my life and i want it back

Re: New custom home made twin charged kit....
 

yea i know the bigger pulley is less boost... but i still get instant boost off the line just not at hard as with just the s/c'er but the top end just keeps pulling with the turbo there where as before it would die out up top.... right now the s/c'er is going all the time... and the boost into the engine is controled by the waste gate on the turbo... it adjusts the turbo so that only 10psi goes into the engine... but im worken on the supercharger by pass valve thats on there so that it will close like normal for launching and give instant boost/quick spool up but then open back up after X psi of boost and let the air pass by the rotors so that its only turbo up top... i am actually setting it up to do Auto X as well... so thats one reason for this...

well im sorry to hear that... but there is no point in dynoing it untill the intercooler and bigger injectors get put in.. which are going in this week end... then i can get it tuned and will have HP/ TQ numbers

Re: New custom home made twin charged kit....
 

trust me i know what horsepower feels like. and petes car on 10 psi wasnt close to 280whp.

my last setup im my gsr was 282whp and it woulda skull fucked his cavalier hardcore.

ive had a 250ish whp built d series hatch and his car wasnt even as fast as that thing was.

cavys make tq which gives you the false feeling that it may actually be making power.

its not talk.

Re: New custom home made twin charged kit....
 

Torque isn't power anymore..? id rather have a car with even torque/hp then a car with high hp and no torque.*cough* Hondas. exception f22 and b20

Re: New custom home made twin charged kit....
 

i should have said compared to a honda. they make even hp tq.

but yeah, still lame regardless. especially with the limited tuning options available

Re: New custom home made twin charged kit....
 

too bad ur fake hks bov is gonna leak

Re: New custom home made twin charged kit....
 

+1... im changing mine out today.... piece of ----

Re: New custom home made twin charged kit....
 

last i heard, torque=power..


since technicaly you can't measure horsepower, rather just come up with it as a function of torque and rpm.

HP=(tq*rpm)/5252

hence the reason honda's make such high horsepower number on shitty torque, they have higher RPMs.

Re: New custom home made twin charged kit....
 

hows it fake? (not being a smart ass... just asking) cuz i got this turbo kit from a guy and it ended up being such a hack job i had to re do it all but i just used the Blow off valve he gave me and didnt even think about it being fake

Re: New custom home made twin charged kit....
 

hotrex, i'm sure you've got alot of experience.. did you stop to consider the power to weight ratio between the civic and the cavy??
not trying to be a smart ass.. or hate on you.. you just cant compare a 280 whp civic with a 280 whp cavy.. my opinion the civic would kill the cavy with equal hp cuz of the weight differences

Re: New custom home made twin charged kit....
 

well its inda hard to tell, take a picture lookin straight into it so i can read what it says inside the bov. whre the triple chrome fin shti is. i wanna read what the valve says. take a pic n post that n ill tell you if its fake, if it is then dont use it. seriously

Re: New custom home made twin charged kit....
 

Why didn't you ever post pictures of the car as a whole? :-*

Your dad's rides look hot. Wheres the Lingenfelter?

Re: New custom home made twin charged kit....
 

where did u y the chage pipes

Re: New custom home made twin charged kit....
 

he didnt have to link, the intake manifold is the supercharger...

Re: New custom home made twin charged kit....
 

i think to make it fair lets make both cars even weight, then see who wins. im gonna have to say the upper hand goes to the cav. no offense to the civ but really a cav with 280 hp is gonna have quite a bit more torque then the civ.

Re: New custom home made twin charged kit....
 

what civic are we talking about here? i know the hatchbacks weight next to nothing.. my car is 2770 with me and a full tank of gass

what do you mean as a hole? the lingenfelter is still on waiting... the dealership got its first 2006 Zo6 in on friday... and we are last on the list to get it in (actually we might even be 1 off the list... but they are trying to get 1 or 2 more in and some people might be backing out... if not we have to wait for the 2007's to arive :( ) but Alberta only gets 18 Z06's a year and 9 come to one dealer ship in calgary and we are #10 or 11 on the list unfortunatly... :( and on top of the long wait even if we do get a 2006... it still has to go from the Z06 plant up to canada to be registerd and then back to lingenfelters shop for 8-12 weeks as they say it takes for the install which is crazy if you ask me... then up to us... so dont worrie i will be posting it every where when it comes in ahaha... and actually i found it funny that its this BIG!! myth type thing here in calgary that this 800 Twin turbo Lingenfelter corvette is coming to calgary since i guess word got out in the dealer ship about it and ------ like the ------- plage ahahah.. and with out me or my dad saying any thing on one car forum... its all over it... so it will be fun cruzing around town with his licence plate that reads "blwn427" or "2fast4u" ahah yes he is cocky with his cars.. but then who wouldnt with a car that puts out 800whp at only 13psi and looks like a normal Z06..


well if it was all even weight and the same driver to make it even as well.. i think the Jbody Might win.. but it really is hard to say... i do know that i do see instant boost as soon as i step on the peddle and by 1500-1600 rpm im already at 10psi off boost... so my power curve is going to be masive... so my low end and top end both and strong... and i definatly noticed it since i like to cruze around town at very low RPMS and now it makes that soo easy to doo then before when it didnt have either the supercharger or turbo

Re: New custom home made twin charged kit....
 

yea... and all the charge pipes are run under the car.. tucked up in around the oil pan and such... makes for a cleaner look in the engine bay... and plus i dont have any more room litterly in my engine bay... i had to take the alcohol injection tank and pump out and im still trying to find out how im going to mount it... i got 2 way in mind... 1 VERY sneaky... it will be mounted in hind the front bumper... kind of where the windsheild washer tank is...

Re: New custom home made twin charged kit....
 

it looks like it says "blow off vavle sequantial"

Re: New custom home made twin charged kit....
 

Did you twin charge your rice also? :3

3 thumbs down:
1 for the rice
2 for the pointlessness of your engine work
3 for getting more money selling a mule than selling your car

Re: New custom home made twin charged kit....
 

why thank you... but i dont see the pointlessness of the engine work... would you like to see dyno numbers of this exact same set up (same turbo and same supercharger) on a 1.6L civic? he has the dyno sheet from just the supercharger, then just the turbo and then both combined... and yes there is a big difference... so again whats so pointless aboutit?

Re: New custom home made twin charged kit....
 

the pointless part is that you only need 1 turbo to blow that engine ;)

Re: New custom home made twin charged kit....
 

funny i dont even think you have a clue?... im running 10-12psi into the engine... there are people pushing 15psi on a turbo system on stock internals on this same engine... so no you dont know what your talking about so why dont you keep your pointless comments to your self untill you know what your talking about..

Re: New custom home made twin charged kit....
 

please post link, i've been looking for that since this thread started
