Expert Turbo on BB Chevy advice?????

[TOM NELSON]

The Callaway set works to a limit the turbos you need are alot larger than whats on the callaway.More Turbo More air More leakage which translates into white smoke out the tail pipe under boost.Its clean and may work just keep that in mind.We have to use a single stage on a dry sump pump.But either way I haven't been able to solve the oil coming out of the tail pipe on start up in the morning whatever.Your driveway gets worked.because the oil seeps through the ring in the turbo.The fuel rails you have I would use but convert the ends to all -8 male fittings and run aeromotive fuel reg and fuel system.Yes you are right you need boost to get that good sound something like 14 pounds just starts to sound good with proper intercooling you can get your 9.2 to work but it has to be tuned right.the blow off you can put a horn on and make sound pretty sweet.but 14 pounds on your set up with 72s is something like 1100 hp can your car take it let alone the motor.You could down size the turbos.but i wouldn't do it that way .I've just used a water meth.injection and to my suprise it works pretty damn good for detonation i've had 10.5 to 1 at 11 psi no detonation .I hope this helps you some Tom.

Tom,

I think I understand. I almost bought a 1987 Callaway a number of years ago. It was a super low mile car but blew a mile of blue smoke on start up.

I guess this is because the turbo sits below the level of oil in the pan and can't drain back when shut down without pumping it. So, if I understand correctly this oil eventually leaks past the seal so that it smokes like a mother lover when you fire it up.

The thing is I have tons of room in this area on my car especially since I shaved the firewall and moved some other things around. I invented and installed electric pop up headlights that allowed me to remove the huge vacuum tank from the driver inner fender. I also squeezed in a vintage air making ample room on the passenger side inner well. The point is I have plenty of space to set up a pair of air cleaners in each fender behind the tire in front of the firewall. There is room for a turbo on each side by the pan.

Mounting it up high and in the front creates new issues with my accessories, etc.

Here is my thinking. Eventhough I did finally score the LS1 I don't plan on using it in the 69 Vette.

I think there is ample room on the Vette to put a single turbo on the passenger side up high which would avoid the oiling issues.

I would like to believe an intercooler could be mounted on top like the Callaway just before the throttle body.

It would be great to have a spare burned up Turbo of the correct size and style for my application that I could spend time playing with in different mounting configurtions BEFORE I drop the $$ on the actual unit (or units).

Been thinking this over and I realize that forced induction is the one area I have never had much hands on involvement.

I could also go to a roots style blower and work out the plumbing to clear the hood or simply raise the hood a tad. However, I don't see the challenge and reward as great in that avenue.

Where do you think I could find a wasted burned up good for nothing turbo to use as a mock up unit?

[TOM NELSON]

I would use a mid frame 88mm.You can call Innovative turbo and see if they have any loaners.

chris, i love your car, infact i was hoping to eventually build something just like it, except turbo power. i know this may be crazy, but why not sell the big block set up as a complete set up and build a nice small block to use instead, you can drop the compression, get something with some more rev to it, and the turbo... that was my plan. regardless, i still think you have the baddest vette ever. everytime i talk about my next project, my girlfriend tries to convince me to build something like yours

ninja edit: hey, just though of this though, why not look at a procharger set up? 10psi, blow off valve, probably be an extra 150-200 hp. im a mopar guy, and like most guys will tell you, in mopar land there is no such thing as a small block. by comparison they suck, notice how almost all pro touring mopars are big blocks? so i went with a stroker/ blower set up, and i LOVE IT

Thanks Majik! That made my day.

Well, since I now have the spare LS1, my other thought was to go turbo on it and put it in the vette to save a ton of weight, go high tech...etc.

Then, I was thinking the big block really makes the car, so if I can polish that off with some forced induction then it will push it right over the edge.

I want to put this engine plan together with a mild re-do on the whole car that includes some upgrades as in larger brakes, cleaner engine bay, better stereo, and each nut/bolt detail item fit and finished as perfect as possible. The first time I put the car together my whole emphasis was just to actually see it roll again, much less attempt to perfect any one aspect.

I am checking with inovative turbo to see if I can get hooked up on something for mocking it up.

Just talked to my buddy Dave www.tropiczoneracing.com . He built the sister (coupe) car to my 69.

He suggested looking into one of those STS rear mount turbos. Here is the idea. Keep the sidepipes but remove the inner baffles. In stead of exiting out in front of the rear tires, turn them in to a Y pipe at the diff and feed into the rear mount turbo. The air cleaner and oiling system goes in the rear. From there I can run a single feed pipe up the belly (which is wide open on the side pipe corvettes) up to the motor and plumb it in.

There is a TON of room behind the diff on the old Vettes occupied ONLy by the spare tire/carrier.

This has a TON of potential and is very exciting to me. The only real trick is getting the sidepipes to turn in and look/work right.

For the love of god don't go the STS route.

As far as the low mount turbo oil seepage problem. If you make one or 2 decent sized drain sumps and let the turbos drain in the sump and then pump the oil out of the sump with something like a rear end pump (can't use the pressure section of a dry sump pump, they don't pump when they suck up air, you need a scavenge section or pump) you should be fine.

also be sure to avoid routing the drain hose horizontally and use as large a hose as you can use

yah, i vote no sts, i know a guy who had one on a ls1 trans am, it didnt last long, he decided to spend the money and build a traditional set-up, works a ton better

I was just taking a buddy out to lunch yesterday (weather was 70 degrees and BEAUTIFUL!) when a 05 Mustang with that silly narrow stripes on the hood smoked me from a roll. I pulled on him at first, then it was like he got hit by a sledge hammer and just exploded. He shot past me and I didn't hear the whine of a charger. After he got ahead and slowed down I noticed black smoke coming out of his pipes and he had aftermarket exhaust. The black smoke tells me he has soemthing under the hood.

Anyway, that was just sick! A stock 05 GT has 300 hp. DANG...I really need this mod BAD!

This is the first I heard of trouble with the STS. In theory at least, it is awesome. It has some interesting features.

The downside is, once the hood is open...nobody can see it. Therefore, for bench racing at the car shows you got nothing. Nobody gets on the ground to look under the rear of the car.
