Well im seeing an increase in intake temps and wonder if that sapped my performance?

Also seen a good gain in torque and in theory thats where the faster 0-60 times are?

just wondering whether any other conclusions can be made.

Unless i am not understanding what the print out is saying you havent lossed you have gained:

Before
Corrected: 172.6
Engine: 174.2
Wheel: 125

After:
Corrected: 178 (increase)
Engine: 174.8 (increase)
Wheel: 134.2 (increase)

I would say that the intake temp wont be right in the first graph as 15 is quite low for a power run. On the road at 18psi mine is in the 30's also.

Oh no I have deffo gained. The 1st read out is from last winter.

What i was asking there was wether the intake temp , if it was lower, would I have performed better?

And does the max rpm being different mean anything?

max rpm is just the rpm that made peak power, just made it different the 2nd time

You know the answer about temps ;) its why we put bigger I/C & C/C setups :):)

You beat me too it! I would have thought there wasnt much more to gain though in your situation Kenobi by going through the hassle trying to drop a few degrees. As Duncan will no doubt tell you he has only achieved max 40degrees while on track, so you sitting on the rollers with a big fan i wouldnt have though youd achieve much less. This is only my opinion though so take it with a pinch of salt ;)
