What turbo exhaust housing to order?

[Junkie]

Have a Precision billet 76mm setup, T4, came off my old Supra build and want to put it on the Cobra. Setup is a 331, descent heads and gonna be switching to a cam/valvetrain that will let me spin to 7400 or so. What exhaust housing are you single turbo/V8 guys running on these cars? Its got a 1.32 on it but from what I understand thats way to big

[greenbullitt]

alot of variables, but id say youll probably end up around .81-.96

give dave a call, hes a ton of help on these things

I was just going to order the housing from Precision but yeah I'll give him a call and see what he thinks

[VaderTT]

I ran a .68 and switched to a .96ar for more topend on my mild 306. MAde a little more HP afaik on my combo.

And Dave had some issues with doing the right thing with customers last year, I think it's gotten better, but I wouldn't go to him.

Almost like the Robert1320 situation.

How'd it spool? What trans?

Sell the precision to some sucka online and get a real turbo

I've had really great luck with Precision turbos

.96 will treat you well

What compression are you planning on using? Also what fuel? Both will effect the way a turbo spools.

full boost by 3300rpms with full exhaust and 3000rpms with open DP and it was a tko600 with a 3:27 rear.

E85 and 9.0/1 Compression

Nice I've got an 8.8 with 3.55's on 28" tires

[VaderTT]

3:55s should be ok with a 28inch tire, lots of people run 3:27s to put more load on the turbo, but have mixed feelings of the taller tire.
