danger New Member 23 Member For: 11y 9m 10d Posted 24/05/20 04:42 AM Share Posted 24/05/20 04:42 AM Hi guys, currently making 450 rwkw with pte 6466 1.07 rear at 21 psi on e85. Has internal gate at the moment but tuner said had to stop it there even though it wanted to make more power because he was having trouble controlling boost pressure. What size external gate would be suffice to push into mid to high 20 to 30 psi and have good controled boost. And yes, motor is built.....any feedback would be great. Thankyou.

k31th less WHY; more WOT Site Developer 29,426 Member For: 17y 12d Gender: Male Location: Melbourne Posted 24/05/20 04:46 AM Share Posted 24/05/20 04:46 AM 44mm is good upgrade size over the internal gate sizes and with the right springs should definitely hold the boost pressure you are requesting.
