Re: Turbocharger? (Jedi404)
Are you familar with the callaway C4's at all?
Doing this is not an easy job.
You will need some exhuast manifolds, these need to accept the size of the turbo and where it will go (next to oil pan or over valve covers).
As far as running that turbo from the A4, why? After going through all the trouble to install it on the corvette, IMHO you should go all out and try to get the biggest turbo on there....... :)

Re: Turbocharger? (Jedi404)
You're Joking Right? You want to put the same turbo that spools up an Audi onto a Corvette? That's hersay!!On a more techincal note, the 350 is almost double what a TT's engine displacement is, so it'd be 1/2 as effective, not to mention the exhaust coming out of your heads and then spinning the turbo would burn the things out like nobody's business (the TT turbo isn't meant to handle 'x' CFM of spent exhuast gasses-the thing's would spin themselves crazy. Do yourself a favor, S-Trim Vortech Supercharger, or a 250 shot of nitrous. While I'm not a traditionalist by any means, these two combos would work out better than putting EuroJunk on your Vette. :D

:lol:
:cheers:
Was doing some cruising around when I saw this post and those pics. Funny how the turbos Q's always come along.
Now I need to figure out how to get guido's PT-88 in a C4 engine compartment! :lol: :smash:

Re: Turbocharger? (Jedi404)
Let's face it, there isn't much room anywhere for turbos. The best place is probably the way Callaway did it, hang the turbos down by the frame rails. The biggest probelm here is that you have to find some way to pump the oil out of the turbo(s).
Callaway did it with some kind of pump specifically for the turbos.
A complete dry sump system is an excellent idea and it will provide a better system for the engine, too.
Another method is to buy a single stage belt driven dry sump type pump that only pumps the oil (actually oily foam) out of the turbos. This way you avoid the cost of the dry sump and keep your wet sump system, but still have something to pull the oil out of the turbos.
As for an exhaust system, the 80-82 Vettes used a factory stainless tubular exhaust header. Small diameter about 1.25" so the velocity of exhaust gases is fast and spools the turbos up fast. Might want to get them coated, but on the outside only, you don't want to risk some of the coating breaking loose and ruining a turbo.
Use a small starter and a remote oil filter and all but the giant turbos will fit between the oil pan and the frame rails.

Re: Turbocharger? (dsagers)
Yes Callway hung the turbos low so you had to have a pump to get oil out of the turbos, and into a reservoir. I think the LPE C5s are the same way.
Didn't Banks have a kit at one time for the C3? The turbos were hung high near the valve covers. The kit isn't in production anymore.
The other big problem with turbo is heat. A friend put a single T76 on his Z28. They had a tubualr front subframe to clear the down pipe. He had problems melting wiring harnesses, power sterring hoses etc. ;) The car ended up having just about everything heat shielded.
http://www.geocities.com/jerrysturbovette/home.html looks like a clean turbo install. Some 3rd gen f-bodies owners have done similiar installs.

Re: Turbocharger? (93Polo)
I was doing some searching around and found some pics of a turbo install on a 4th gen F-body. Those turbos hung low as well. there appears to be some sort of catch can attached to the turbos, it looks like a 6" long cyclinder about 2" diameter. Still not sure but it look as if the oil drains out of the turbo by gravity into the black cyclinder, then and electronic scavageing pump picks the oil out of there and brings it back to the oil pan.
or maybe it is for cooling, I cant figure it out.

Re: Turbocharger? (bill mcdonald)
I saw the dyno sheet for that Supra with twin T66s, and it made me sad. It made me sad when I realized those guys thought they were making real power. 100hp at 4000rpms, is just poor, we aren't all about that sort of thing here on Corvetteforum.

Re: Turbocharger? (korvetkeith)
Hmm i HIGHLY doubt that supra was making 100hp at 4000rpm, considering it makes about 850rwhp at 7800rpm... :seeya. The twin's in the supra operate in such a way that one comes on from idle to redline, the second enters in at 3500 rpm. This Gives excellent performance from idle up. Lets try not to be elitist, and despite the supra having *only* a 6 cylinder, it is still one hell of a car; i'd drive one any day.

that twin T-66 car actually made 200 HP at 4000 rpms! :D
The rules for how a supra operates change when you up the size of the turbos :D
Thats whats happens when you put huge turbos on small engines, it just takes more RPM/exhuast gasses to get them spooled up.
here is the twin T-66's dyno chart! http://www.supraforums.com/supravb/s...+wouldnt+spool
Now take the Single T-66 cars, they are a lot faster, but the trade off is the turbo spools up a bit later in the RPM bands (some call it lag), but it makes a lot more power when it finally spools up!
Now twin T-66's.... No way that car is running sequential! it would be pointless. Those Turbo's are too big too spool in low rpms!! espesially with 1.5 L driving each one.
It does not appear to spool up till about 6000 rpms! That is one narrow power curve. I bet it is fun to feel 400 to 700 hp in about 1000 rpms though.
That twin T-66 car if we are all talking about the one in the topic I posted made 718, still impressive (untuned)at 18 psi, yet I bet it lags like crazy!!!

Re: Turbocharger? (bill mcdonald)
Mmmm pretty. True there is no low end torque. But i think that would just make take-off that much easier to control. What a rush at high rpm's. I drove a 1st Gen Eclipse GSX w/ ported 16G. Given the AWD, it took off tramendeously. On the highway it just would not stop accellerating. There's just something about turbo's. :)

Lol jenny you sound like someone that hasn't been in a blower car....when you do, you'll stop saying "there is something about turbo cars" and say "There is definitly something about blower cars." :D
