i was at a car show today, there was a portable dyno and i thought what the hell, i just put on my comptech blower with after cooler and t1r exhaust sooooo lets get some numbers. 2 pulls...... first pull 209hp at 7100 rpm steadily climbing to that point then a 65hp drop over the next 2000rpm it was a sharp drop then slow increase to 190hp at 9100rpm .......next run was similiar. possible dyno problem ? my car feels really good and pulls hard all the way thru the rpm range....has anyone ever seen or heard of anything like this ? or does my sc s2000 only have a best of 211hp at 7100rpm

 

I'd say dyno, otherwise something would have to be seriously wrong with your car. With just your exhaust you should pull a peak power of that much, so being S/C'd should yield much higher numbers.

 

If you cant feel that drop, then I'd bet it was a dyno problem...a drop that dramatic would be noticeable. VTEC is only a 20hp change and very noticeable.

I hope you didn't have to pay for that dyno run.

 

HP and boost should rise all the way up to redline. Dropping power after 7K could be your belt slipping. I just checked my dyno graph and at 7K I'm right around 215-220hp.

 

i did pay for the dyno run....20 bucks, get what you pay for i guess.

 

whats your HP with SC?

 

Also I read on your sig that you have gears...that can also throw the Dyno graph off if gears arn't taken into consideration and then calibrated for right?

 

is that at the wheels? stock ap2's run that at the wheels

 

gears have nothing to do with a dyno pull

 

what is the purpose of this question? im sure dyno prob.
