...because these just came in the mail. A friend and I were approched to build a turbo kit for Chevy BB 502. So of coarse we accepted this challenge. The goal that was given to us is to push 1000RWHP on pump gas and 1500RWHP on a high octane setup. I think these bad boys will help the cause.

Drum roll please.............Twin Garrett GT40s

 

One more just for good measure. Sorry this is all the owner really wants to be mentioned publicly but I'm sure you'll be seeing it in a year or two.

 

DAMN, big-block with twin-turbos??? Overkill don't ya think?

Oh man, I can only imagine...be sure to post pics of the engine when it's finished!!!

 

I demand a test ride when done!

 

HA, ok next time your in IA.

 

So what's the lucky vehicle to get that beast?

 

Can you hear me now? Good.

 

LOL!

 

All you have to do is say, Ear muffs, then you can say anything,....

Gotta love "Old School"!

 

 

wow!!!! those are some large *** hair dryers!!! that engine is going to need to be stout just to push those things... cant wait to see the end result!!

 

i can only imagine what a monster that is going to be...

CEO

 

how big are those?
looks like another interesting project.

 

 

They are GT40s, projected boost is 10-16psi

Compressor: 88mm, 54 trim, A/R 0.72
Turbine:77mm, 73 trim, A/R 0.94

I personally think they are a bit small for my liking butt they will certainly spool well and hit pleanty hard. Remember this is a 8.3L engine.
