Just out of curiousity, what are the 3.4s putting down on the dyno?

I have the fabspeed stage 1 on my car(3.4L)...fabspeed is claiming 297hp to the wheels(3.6l). Has anyone done this independently?

I know there is difference between the 3.4s and 3.6s but how much?

I have Fabspeed headers, exhaust and CAI. Power improvement was not felt by my butt until after the flash. Everything else was just sound.

Which flash did you have done to your car and did it make a very noticeable improvement?

What do you think your HP figures are with those changes to your 911?

I had the Farnbacher Loles flash twice. The first time was to advance timing with the CAI and exhaust package. Throttle response was noticeably better but not necessarily quicker. The second flash was after the installation of headers. Timing was further advanced tying the CAI, header and exhaust in one package. Midrange torque is more noticeable. I drove a stock MKII 3.6L cab back to back and my car felt just as quick if not with a bit more punch.

It might help to tell us all what constitutes a Fabspeed Stage 1???

My 3.6 with x51 headers, fabspeed cat bypass pipes, fabspeed mufflers and the evoms intake put down 299RWHP.

Fabspeed stage 1 consists of headers, highflow cats, mufflers, ecu re-flash. I also have fabspeed intake, which is seperate from the stage 1.

Sorry to revive an old thread but what are FBay Headers?

Graufuchs

I think hes saying fleabay aka EBAY headers.

Maybe we should dyno some cars... I have a C4, so can't put it on my dyno.

Oh crap... did I say out-loud that I have a dyno?

Ritter: Why are you running ebay headers? I thought that they lost horsepower and were Satan's gift to Rennlist?

Ritter v4.0

All eBay headers not created equally.

Interesting stuff.... I get protested and dyno'd regularily at NASA races. I'm always right around 272 in my 3.4. I'm basically stock with 3.8 997S exhaust manifolds (not headers but noticably larger ports), Fabspeed cat delete pipes w/open exhaust, and GIAC's street flash.

I'd love to get to your 284 Ritter, any suggestions?...
