Stop the presses!


This is so cool!

It is so easy to skip over and miss good things in some of these threads.

There is a very good chance this is very, very close to the Group B build!

I bet that HP is at 1.3 bar.

I am dying to learn more about the turbo and see a picture of such an intercooler and exhaust.

They also note a special exhaust with 'waste gates" plural.

Wow, wow, wow!

That HP is right what I was coming up with. 400hp at .9 bar is a well accepted data point. Thus, (400/1.9) x 2.3 = 484hp potential if efficiency did not suffer at higher boost.

I have heard from others the motors were tested open exhaust at what boost level I do not know but maxium set up overall I would assume. . So now after the US restrictions, who knows. We just had the turbo out for oil seals to Bob @ Durabilt turbo rebuilders Chicago. They usually have a 1 day turn around however he said the turbo rebuild parts took a week to get as the Turbo was a race hybred and was similar to the much later KKK 7200s inside. Anyway I do not know what that has to do with the HP output other than he said it was well suited for the motor spec, by it's internal condition.img][/img]
