What percentage do you have yours set up at out the gate and how long before it is at 100%??

have been told not to go higher than a 168mm crank pulley here in South Fl... My friend ran a 180mm on his car with no problem and I see youre running a 185mm... not sure why everyone is telling me to stay at 168....Awesome run!! glad to see it done by a local at a HOT track.

Miguel is using nos and ice at the track. Nos cools like nothing else, also in sl if you go 180 or higher you will need much more cooling than a heat xchanger. Killer chiller and or water injection will be needed to help control heat and timing being pulled

Timing gets pulled around 105-110* it's depending on the tune. If its 95* outside you are already at 120-125* iats if you are lucky before the pull, what do you think will happen when you get to 140-150* iats?. Lots of timing will be pulled. And power will be lost

If your friend is not logging he has no idea what the ecu is doing to control timing and the initial torque is most of the feeling he will get

Damn... Perfect run

Congrats

Sweet color 55!!

thanks for that info! so when hes driving around on the street with a 185 increasing IATs (im assuming no NoS and ice for daily driving ), would he be making similar power to someone running a smaller pulley in some instances?

Anyone driving with a 180 or larger in 90* weather is not making top power in that heat without a reservoir of cold water via killer chiller or water injection
