[QUOTE=davidvonyork,Apr 8 2007, 04:48 AM] Well as some of you may know i have a single...its a hks can with i think 2 1/2 inch pipes....i also put a invidia test pipe (i know Ricky

 

Good Point Whitedeon...

Thats why I havent done any engine mods yet for that reason to go boost. I am still undecided which way to go ...custom or Inlinepro kit.

 

Hey man.

Can't go wrong with Inlinepro. They do very nice work. For reliability purposes and financial reasons, you may want to consider getting a supercharger. I plan on getting a Vortech, smaller pully, headgasket and AEM EMS. This will be good for right around 350 rwhp while still being very reliable.

 

Or pay 156. a month at 9% interest for 5 years on a 07 gsxr600 and get 0-60 in like 3 secs


very tempting.......

 

lol. do it.. david.. the 250 with bolt ons will kill you...

 

As a side note -- I will be at the AutoX on the 15th...

Might want to do a baseline dyno to see if you're actually realizing the gains you suspect. It would be a shame for you to invest in more bolt-ons only to take a step backwards with a bad mod. I knew a MY '00 owner that invested about $7K and gained about 7 RWHP. The car certainly pulled harder but the dyno plots showed a different story. In an unrelated instance another owner added a header and lost HP despite mfg. claims. We saw the same thing happen with some exhaust and intake mods. No experience with any dyno shops down your way. I've only worked with tuning shops in Dallas and Garland.
Sounds like you'll be looking at FI soon.

 

Just FYI, I did a back to back dyno of my stock exhaust vs a 2.5" dump off the cat just rearward of the axle, and it gained about 4whp peak, but it was all on the VTEC side. The plot looked exactly the same pre cam-switch. There is a significant amount of valve overlap in VTEC which benefits from the big pipe.

And Backpressure is a bit of a myth. The vast majority of the exhaust pulse management is happening in the header, and the collector. If you have a stock header, and are running a test pipe with the same size piping as the header collector, running 3" exhaust south of that shouldnt be a problem.
