6768 turbo ?

[434nova]

I know precision rates this turbo to 935 hp , but b if iy has a E cover with a 3 inch inlet and 2 inch outlet can this turbo still make the 935 or will it need a ported h cover. So my question os how much hp can be made with the small e cover. Thanks

I don't know how much power it will make, but I had a 6768 with an e cover (3x2) and I went 9.7 @ 140 at 3700lbs with a 1.5 60'. 234" engine.

Looking to put the 6768 on a 235 ci with gn1 heads and a 206 roller cam. My current turbo which is a te45a made 560 rwhp on 26 #s of boost. Found out the 6768 turbo I am looking at is a h cover 4 inch inlet 3 inch outlet. Wonder how much more power I would make over the te45a. Looking to push close to 30 #s on the bigger turbo.

My engine had gn1's also. I ran my passes with a little less than 30 psi.
You should see a decent gain switching. What exhaust housing is on it

I believe its a .85 but am waiting to find out for sure. What ar did you have. Also what size injectors were you running. Thanks

I had the 85 and used 95's

The 9.5 ptc converter works great with that turbo. I had a 17 blade which was a little tight.

Biggest thing that held my combo back was the engine was less than 8.5:1 compression.

Why not run the 45a at 30psi before you upgrade and see what that does for you?
