O.K, I have had my 87 gn for about four months now and frankly, its just not running like I think it should I took it to the track and I ran 4 times the lowest being 10.446@72mph in the 1/8th the rest were between 10.5 and 10.7. it was around 70-75 degrees. The only mods are an old hypertech chip, msd precut plugwires,
dual flowmasters whith no cat, k&n cone, adjustable fuel pressure regulator, and the engine has around 35000 miles on it!! So, obviously this must stop at once!!
When I launch I power brake to about 2-3 psi (that is as much as I can get, I mean it boosts to around 2 or 3 and will not get any more, the rpms and boost stay the same while power braking) going down the track I get about 12-14 psi on my aftermarket boost gauge so I know it's right.
I'm running bfg 275/60's on the rear so the only tire spin I get is the tiny bark into second.
The only thing that I can see that would cause this is the cracked headers BUT, there are only three small cracks in them, COULD THIS BE THE SOLE CAUSE FOR SUCH POOR E/T's??!?!??
From what I gather the times for a STOCK 87 are around 9.9?? is that correct??
OR, am I just crazy?
Thanks,
p.s. where can I find some GNX style rims??
