will this turbo idea i have work??
 

whats up guys new to the site here, great site i hope to learn alot here, anyway...heres what i want to do, i have a 96 camaro ss and want to put a small sized turbo on it, im thinking about a te28 or a te32 since space in limited on an lt1 car, but this is the idea i have, i want to take a small turbo tap into my y-pipe for the down pipe and tap into the other side of the y-pipe for the exhaust outlet, with the turbo being located along side the lower fender well, i then want to take a small intercooler and mount it where my washer fluid bottle is in front of the radiator, since space is a big issue i will be using a 2 inch flex style hose to come off the compressor and snake it around the front of the car to the intercooler out the other side of the IC and make a custom elbow for my throttle body with a long spout underneath it to suck in the forced air, do you guys think this will work? ill worry about the oil lines and stuff last as i think that will be the easyist part, also i want a small turbo so it spools up quick and im really only looking for about 40-50 more horse at the rear wheels since the engine already has a cam rockers, gears and a 100 shot, im just looking to wake it up a little more not really looking for crazy amount of boost, about 4-5 psi would be good, so what do you guys think... thanks

I just read that, and I have no idea what you mean... Detail the part about "in the y pipe" a litte more. Also, on a v8, you WILL need either two turbos (one for each bank of four) or a MUCH larger turbo.

im in the procvess of using a t3 60/63 on my friends 94 lt1

Re:will this turbo idea i have work??
 

johny,the car has the stock exhaust manifolds, with the y-pipe coming off of it to the cat converters, so i want to tap into the y pipe to get the exhaust pressure, and then tap into it again to let the exhaust from the exhaust side of the turbo back in, and yes a larger turbo would probably work better, just curious if that will work by tapping into the y-pipe,

Re:will this turbo idea i have work??
 

hotrex, fill me in on your friends lt1, is it a home made kit ?

Re:will this turbo idea i have work??
 

there might not be a whole lot of room, but there is enough room in there for a turbo , a smaller style turbo and a log type manifold, that combination is about the size of aftermarket headers for your car (equal length ones not block huggers) I'd do two T3's, one on each side with a log style mani, run the charge pipes up to the front, through the intercooler and into one pipe to the TB then run the downpipes down to a Y pipe into your normal exhaust, or go dual exhaust cause you can. It'd cost a little more, but your ---- wouldn't be all ghetto like it would be with your stock headers in place. Don't skimp on ---- and you'll be happier with the result (esp because you'll make a bunch more power.

Re:will this turbo idea i have work??
 

Turbo Engineering put a real nice looking one together with a T04 turbocharger that will produce power levels greater than 500 horses.

It's pictured in Maximum Boost on page 22.

If I was building one for that car, I'd copy that one.

Re:will this turbo idea i have work??
 

yea im looking for ideas now, i dont really want to spend $4000 for a lt1 kit, i want to do this myself for about $1200 if possible,

Re:will this turbo idea i have work??
 

you could feasably do my version of the setup for $1500

Re:will this turbo idea i have work??
 

what do you mean "tap" into the y-pipe for the exhaust pressure....all the exhaust has to go to the turbo if you want it to make any boost. if not, the exhaust will most likely take the easiest route, around the turbo

Re:will this turbo idea i have work??
 

i want to mount the turbo inbetween the y-pipe just before the cat converter and exit the exhaust side of the turbo out the other side just after the cat, you can see what im trying to do, go to STSTURBO.COM and click on the camaro, they specialize in rear mounted turbo systems

Re:will this turbo idea i have work??
 

I could go on for hours about why rear mounted turbos suck ass and the company building them quotes all the wrong reasons...

I'll try to skip that for now... Can you post pics? The easiest thing to do is take some pics of your $4k system and copy their layout. If you could post pics of your engine bay we could probably make suggestions.

Re:will this turbo idea i have work??
 

i'm pretty sure that the y-pipe is like 4inches....you would have to go pretty small for a small turbo like that...look for a T60 something

Re:will this turbo idea i have work??
 

the y-pipe is like 2 1/4 inch then it turns into 3 inch all the way back over the axel out to the muffler, hackish, what about the rear mounted turbos dont you like,

Re:will this turbo idea i have work??
 

I would not copy that system, you have to pump oil to and from that turbo, to much ---- to go wrong, and your air filter is almost draging on the ground, my momz could come up with a better system than that! Make it simple not stupid. good luck!

Re:will this turbo idea i have work??
 

I thought the $4k system was the one made by cartech. If anyone can design a good turbo system Corky Bell can. If you want DIY then copy his design otherwise just save up and buy it. Or send me your mulletmobile and a cheque for $2k... :)

-Michael

Re:will this turbo idea i have work??
 

mulletmobile?? care to explain in more detail

Re:will this turbo idea i have work??
 

The system that I mentioned before has a front mounted turbo (& I said COPY it...not buy it).

Check it out man...You'll like it.

Corky Bell thought enough of it to picture it in his book about designing & installing turbo systems.

Re:will this turbo idea i have work??
 

ok... people are putting down the y-pipe idea because it's not very efficient at spooling a turbo compared to manifold mounted turbos.
try this:
hold your hand about a foot infront of your face. blow on your hand and count how many seconds it takes you to run out of breath. next, do the same thing with your mouth open so you're just exhaling, but with the same amount of airflow you did before (it should take you the same amount of time to run out of breath). it's the same amount of air, which do you think would spin a fan better?
it's the same deal with the engine and turbo - exhaust is released from the engine at super-sonic speeds (or so i've read)... if you put the turbo right next to the exhaust outlet, you can take advantage of that extra force.
by putting the turbo down by the Y pipe, the exhaust pulses have had time and volume in which to slow way down, even out and cool off somewhat, releasing energy that the turbo could have made use of.

Re:will this turbo idea i have work??
 

can you give me some reasons why you dont like this one? I was currently building one for my v6. But since there are drawbacks, I'd love to hear them and replan my system.

Re:will this turbo idea i have work??
 

For one....feeding the turbo with oil way back isn't that difficult, but I would worry about my oiline being thata long and all the way there. And the turbo's return line is gravity fed, so it needs gravity to go back to the oilpan. Now you have it all the way back there ...you would need like a pump, to pump the oil back to your oilpan...too much hassle for me.
As for everyone wanting to build a V6 or V8 turbo...I am going to build one(V6 turbo) to and using a T04B and am going to mate the two banks together into the turbo. I still haven't gotten my turbo yet :(. If I would go with a small turbo I would do it like bambooseven said. nice small logstyle mani's and a T3 on both side. It should fit perfectly and give you good results. You'll be happy like that. If you want ony a little bit of power do it on one side, but you'll be wanting more so I would suggest do both sides, but it's up to you. And the turbo sits high enough for the oil to return to the oil pan

Re:will this turbo idea i have work??
 

i know a log style manifold would be better but im really only looking for another 50-60 hp at the rear wheels, since lt1's have the hyperexploding pistons so i ony want about 5 psi of boost, so i think by mounting the turbo inbetween the y-pipe would work out ok, and a small pump could feed the oil back into the valve cover through a custom fitting screwed into the valve cover, like i said this is going to be a low budget keep it simple project,

Re:will this turbo idea i have work??
 

Nothing really simple about a turbo system & even low boost systems should take advantage of well designed plan.

Why only settle for an extra 50-60 hp? Cover all your bases, spend a little more time & money and get better results. Avoid getting into a position where you wished you did it differently from the beginning.


If you do the system in this way, you'll be happier, create more reliable power & have less headaches.

Re:will this turbo idea i have work??
 

i hear ya on that one but like i said, the lt1's are very high compression from the factory and the pistons are weak, i dont race the car at the track but once a year and really only take it out on weekends, so thats why im only looking into about 50-60 more hp, and want to stay with a small turbo for space issues and something that spools quick for those 1/8th mile blasts from traffic light to traffic light, do you think a T-28 would suit my needs?

Re:will this turbo idea i have work??
 

I think that's too small for a big V-8.

Check out the compressor maps after you figure out what your max cfm will be. This will help you decide what turbo will suit you needs.

Edit: Buy the book Maximum Boost for detailed instructions on how to go about the turbo system design process.

Re:will this turbo idea i have work??
 

Z28, why dont u just spend $500 bux on a nice nitrous kit and save yourself the headache of putting together a turbo kit that will cost you more than that... Honestly though, if you rarely go out and race and just want that quick burst of 50-60HP... nitrous at WOT will make you happy! Unless you like the "PSSSSSSSSH" ;D

Just my $0.02...

Re:will this turbo idea i have work??
 

good point

Re:will this turbo idea i have work??
 

i already have a compucar wet nitrous kit on the car now, 100-150 shot, but the bottle runs out too quick :) thats why i want a turbo so the power is always there and i could still spray as well...

Re:will this turbo idea i have work??
 

Ok, first mulletmobile comment. Transmarobirds are exactly what the mullets drove way back when I was in highschool. Mulletmobile colloquially here refers to any V8 RWD muscle car, but more so the 80's and later models.

Here is what I wrote on the subject back in October...
They have a nice writeup on what turbo lag is. Unfortunately they're confusing boost threshold with turbo lag.

They're also making piles of claims about turbo efficiency and such by moving the turbo away from the manifold. Unfortunately they have no idea about ideal gas laws. They said that the denser exhaust gas at the tail pipe is more efficient to run the turbo. Unfortunately they forgot that the exhaust is about 1000 degrees cooler back there so you've got a magnitude less volume in order to run the turbo itself.

Let's not think of the FOD possibilities back there. Don't drive your car on a dirt road or as some people have pointed out in the rain. I don't think the heat would be a huge issue since the exhaust will be very cool by the time it makes it back there.

Most of their dyno proof consists of gtec pro printouts. Finally they made 520bph on an LS1 motor and 10 PSI. Running an amazing stock fuel system and an AFR of about 13.5:1. I can only wonder what sort of fuel... C16 anyone?

Oh but wait there is more. That's an air filter down there. You want to suck ---- from behind your wheels into the engine? HELLO!!!

Someone pointed out their marketing photo:
http://i.b5z.net/i/u/1473169/i/Why_Remote_Mounting.jpg

To which I replied:
Don't forget that by the time your exhaust gets down that far it won't have that kind of heat left in it. I wouldn't recommend you touch it, but think about how hot your muffler is in relation to your manifold.

Today I'll add the following turbo lag point...
Making boost is basically a feedback loop. The more air you pump into the intake the more exhaust volume you will get out and subsequently faster you can spool the turbo. In this case you're pumping your intake charge from the back of the car to the intake. That's a lot of charge volume to pressurise when you get on the throttle. I believe it will severely affect driveability - ie sluggish throttle...

Re:will this turbo idea i have work??
 

thats a cool pic lol

Re:will this turbo idea i have work??
 

I'm not sure if the system pictured in max. boost is with stock internals.

But, if it is...then I would say that your compression is probably not as big of a factor as you think. I mean, they're producing over 500 horses.

What are you producing with your nitrous system?

Re:will this turbo idea i have work??
 

strech, just wanted your awnser to the mulletmobile, im stll stuck in the 80's but i dont have a mullet..thank god, and my fav band is still MOTLEY CRUE !!!! good point on the rear mount set up, well said, hack.. i think on my 150 wet shot im at about 425 hp at the rear wheels, and 330 rear wheel hp N/A

Re:will this turbo idea i have work??
 

Have you bought the book yet?

Re:will this turbo idea i have work??
 

i got one off ebay, should have it by next week

Re:will this turbo idea i have work??
 

that takes a while

Re:will this turbo idea i have work??
 

Good.

You will learn a lot & read it more than a few times I'm sure.
