Has anyone dynoed their turbo car with the cat on then pulled it off to see the gain? How about dyno with the 2.5" stock cat and then dynoed with a 3" cat?

Anyone dyno their low port turbo car with stock cam then bolt on 91 cam? Or, and this includes high port, dyno stock cams then S3's? Turbo setups only please.

I am trying to decide what to do next. Please give any info or advice based on real world experience.

I have heard of 40+hp with the S3's and dyno tuning. A while ago someone posted the dyno results with stocks then the S3's very impressive.

A couple searches later and the answer for the cams click here,

I thought someone posted about the cams but I searched for quite some time and couldn't find anything. Thanks for that info.

I would still like to know more about stock cat and 91 intake cam numbers on turbo.

I have the 91 intake cam in my car and we will be doing a run down on that with the turbo system with a Greddy exhaust and a 3inch exhaust then another test with S3's and both exhaust systems... It will be a few months if you wanna wait that long but I didnt think so :p Hope someone already has these numbers so I can know as well...

I would like to see some numbers with the cat pulled off too. I'm still running stock exhaust with the cat on. I think this is holding me back a lot.

I want to see the exhaust comp.

TOM, THAT IS A "SICK" SIG THERE!!! :cool:

Uh yeah, a nice 3" exhaust with a test pipe should yeld you at least 20 hp depending on how much you turn up the boost.
