how much boost

Boost 

Hi Matt, A stock T5 Will boost up to about 11psi If you fit a manual boost controller it will boost up to 13psi before the ecu automatically cuts over boost. If you get your ecu chipped, and cancell the overboost option, it will boost up to more or less anything you want, although i would strangly advice not to go over 20 psi unless you want very expensive repair bills. Regards Stuart

Be especially careful at this time of year when the air is much denser, I'm having mine repaired at the moment and looking at a bill of 2K plus :angry2:

hi, ive been led to believe the newer T5's (96 ish) can deal with 18 psi without uprating the c rods, the older T5's apparently have weaker rods. an mbc can give you 14-15 psi before cutting, if you want more psi you need to get in touch with a tuner that can remap or just remove the boost limit. be very careful and do your research before playing with "boost limit" removed motor. wayne
