Thoughts on what this combo might run

[84gnguy]

stock 87 GN (motor,convertor/trans,rear and suspension)
mods are:
K&N open element
ported exhaust housing,3" Kirban downpipe
test pipe,Hooker 2.5" exhaust
Duttweiler neck,wastegate set for 17 lbs.
TT 93 octane chip
Hoosier Q/T DOT Pros 26x15x9.5"

this is a street driver,not looking to add alky or anything.I have a blast with the car as is.

Thoughts as to what it would run ET and MPH wise assuming a 1.8-1.9 60 ft.
I am guessing mid 13's around 100 MPH

if you can hook and do a bansai launch maybe 10psi i would say 13.20 at 100

we all said that

well,I am hoping for at least stock GNX or 89 Turbo T/A performance,but with sticky tires.

Sounds reasonable...

I ran 13.30 on a similar setup two years ago. This was with a 6 PSI launch & a 1.85 60'

Many people scough at a 13 second car. But in reality, a 13 second street car is pretty dang fast.

No other mods!!:biggrin: Thats what I said $15000.00 ago!

No $hit right. I said when I bought my car, "If I can run low 13's I'm more than happy"

Well, then larger injectors, dutt-neck IC, & alky happened to fall onto the engine. Now I'm running high 11's low 12's, and better heads & a roller cam might be instore.

I see more mods in your future! All you need now is a good launch, some race gas and more boost to dip into the 12 sec club.:smile:

My GN is almost the same, mostly stock, unported heads, stock cam...stock neck IC...

Kirban downpipe
Test pipe
Factory y pipe to some kind of cheap dual exhaust
60# inj
Adj FP Reg
Red's Voltbooster
Red's XP pump
Hotwire relay for fuel pump
Various JayC and TT chips for the 60#'s

Lately I've been running closer to TSA setup with the stock airbox and a stock filter.

1.8-1.9 60 foots

17psi = 13.3-13.4
19/20 psi = 13.0's

One time I dumped in 5 gallong of 110. Bumped the timing to 24* and hit 25 psi in 1st and second on a 15 psi parking brake launch and pulled a 1.67 60 foot, but I let off after the boost gauge was buried and I got skeeered even though it felt great and no knock, probably was an easy 12 sec pass.
