so ? what do i need to understand

your gas?
wich dyno ?

wanker

Temperature can affect a dyno by as much as 15 hp. Also EcuTek > Uprev.

FWIW, I'm a bit skeptical of the design of the Takeda cold air intakes.

Just my two cents.

Darkchrix

me too but it seems similar exeprt the filters

nomodsjk

Yea ive had a difference of around 15whp and the only thing that changed was the temperature outside when it was dyno'd

Tire pressure, tire position on the roller, there are so many variables.The end number really doesn't matter much, you need to compare before and after numbers from the same dyno, preferably from the same day. There's always going to be someone with a high dyno sheet, doesn't necessarily mean their car is making more power it could just be that machine reads a little higher.

I'm using ECUTek, Berk HFC, FI CBE, Stillen G3 Intake:

Base run was: 303 HP @ 7400 / 244 TQ @ 5200
Final run was: 316 HP @ 7400 / 251 TQ @ 5100

My AFR wasn't too far off, so I was surprised by how much I gained actually.

This is a good read about Dyno variables if you have a moment, its not real long, and it gives actual examples.

i was drifting on first and second gear

JTM88

Reaction time doesn't affect your ET

Think I found your problem, drifting and drag racing are two different kind of racing

I think its my gtr rims .. too heavy and big

Chuckles

Its not the rims. Its throttle control. I'm guessing you're to heavy on the gas. Everyone does it the first time they are at the strip or track. It fairly amazing how much faster you can go with the same car when you can smooth out your inputs. Getting to be a pro at that will drop more time that different rims ever could. That just my two cents. YMMV

gbrettin

You are running 91 octane... That might account for some of the issue. Others are getting more aggressive with their tunes with better gas.
