drbowser3;1156680 said:My 89' made about 460-480 on a daily basis at 17psi. I always drove my car hard. My motor had 160k miles on it, all that was done was a MHG and ARP studs.
My setup was near identical to yours. 35r, AEM, Custom Piping, eBay manifold, tial gate and bov, 550s.
@21psi my car made 501, in the heat of florida and after 9 consecutive pulls.
As far as how reliable, I drove the car daily for over a year and a half and it would still be running strong had it not been wrecked.
MKIIINA;1156682 said:the biggest thing is the tune. that will determine how long it will last. why did you go with the 720cc injectors? other than that looks like a decent setup, watch for detonation and it should last a while

The questin isn't the 7M, it's the question of your particular 7M's condition and tune.
