Do you have the dyno sheets available for posting? It would be interesting to see the difference between the two. Are the two runs corrected equally so they are comparable? Thanks for posting. What are your thoughts?

Re: Flowmaster Cat Back and a Haibeck chip
Remember, peak numbers alone don't mean much. Marc says "around" ten so maybe the chip only added 7 at peak but, it may have added 15 or more elsewhere. What I would also like to see are the torque numbers from before as I assume that they were close to the HP numbers. If so, then that's a nice gain. Another good comparison would be how much the power falls off up top now as to before. I would rather gain 20 hp every where and only 10 at peak instead of 20 at peak and only 10 everywhere else. JMHO.

Re: Flowmaster Cat Back and a Haibeck chip
I have them not sure of how to post them.I f you drop me a PM with a fax # I will fax them to ya on Monday.
The first one from 11/2 was done @ SGC on a Dynojet and does not list torque it also is listed as HP & MPH.. The two pulls today were done @ Vengeanec Raicing on a Dynojet also, it lists HP & RPMs. and yes I was looking for a 20hp gain also. Not sure of how good the dyno was as both runs are missing some of the graph lines?? Guess I can't complain as it was free... I sure someone who know how to read them could tell more than I can...

Re: Flowmaster Cat Back and a Haibeck chip
You really need a torque curve to see whats happening. Air/Fuel ratio is needed also, that way you can tell if you're (the engine) is fat or lean. You have got a great tq curve Steve. It comes up quick and stays there for a long time. Your car should scoot.
I would say that given the variations between Dynos there has definitely been an improvement.

Re: Flowmaster Cat Back and a Haibeck chip
Mike,
Thanks for posting the graphs for me..was great talking with ya. John, it pulls good and I'm happy with the gains..When I have the time again I'll have to get down to SGC and have a good dyno run with A/F.. I did not see this before but the run at SGC is STD and the new one is SAE.. |

Re: Flowmaster Cat Back and a Haibeck chip
Notice the SGC dyno was corrected to STD, the recent run was corrected to SAE. The Dynojet STD correction is normally around 2.5% higher than SAE J1349 standards.
I would suggest your baseline was more like 316 rwhp (SAE), thus the gains more like 23 rwhp. The Flows are probably responsible for about 1/2 of that. Todd |

Re: Flowmaster Cat Back and a Haibeck chip
thought I would share what i modified on the flowmaster system that did 2 things 15 more rwhp and made it sneeky quiet at the same time. I was looking through jegs' and came upon this ultra flow muffler that had duel in and outs . i got a 3in one and replaced the resonator with it . went 3in off the headers to the x pipe muffler then just used the exisisting flowmaster system from there. it is as quiet as the stk system when cruizing and just loud enough when you get on it . Its about 40% quieter than the original flowmaster . Now i can plant my foot without worring about everyone hearing (cops) and she is faster too. one guy says its sneeky fast. that this car tooo quiet to be that quick. that of course after I dusted his 04 z06
