Engine/Transmission (1994 - 1998) SPS 62 Boost

[MAleksandrowicz]

What is the most boost recommended out of a Super Phat Shaft 62. I just put it in and I got it to 55psi and I wasn't full throttle yet so I let off and haven't let it go past 45psi since then. Just don't want to break anything.

I was told that charger is safe to 60psi. I run mine 55-60 and so far all i have hurt is the head gasket.

Your going to find out that it will spike then level off a little lower once the gate is opened up... ... ... you'll hurt something else before you hurt that turbo.



You can't even begin to imagine how much I have thrown at mine in over 2 years.

Thats all I needed to hear. Thanks

yeah, I was running mine at 55psi for a while. it's now at 48psi, and I keep thinking I should turn it up as drive pressure is only 41psi! but it's running so well, whenever I drive it, I never think about turning it up

i had a 60psi boost gauge and it only took a about 10 seconds before it was pegged. my guess is i was running around 70psi. this was on a super phat shaft 62
