theres a boy at my school that has a black 87 monte grand national all hes got on it is a adjustable wastegate and fuel pressure rgulater along with some other things that ive done forgotten about , hes pissing me off so im going to go race him tonight. does any one know what them cars run and the specs, will i be able to take him in my 97 rx7



:twisted:

what car does he have? buick grand national? and you have a what? 97rx7 where are you from?

If it's a Buick Grand National, it ain't slow. I suspect a healthy 3rd gen could beat one.

This is from musclecarclub.com:



Production: Grand Nationals: 20,193 GNX: 547

Engines: Grand National: 3.8L V6 Turbo 245 bhp @ 4400 rpm, 355 ft-lb @ 2000 rpm. GNX: 3.8L V6 Turbo 276 bhp @ 4400 rpm, 360 ft-lb @ 3000 rpm.

Performance: Grand National: 1/4 mile in 14.23 seconds @ 98 mph. GNX: 0-60 in 5.5 seconds, 1/4 mile in 13.43 seconds @ 103 mph.

ok i was wrong i just talked to him, its a 87 buick grand national intercooled with a t49 turbo, 55 lb, injectors chip, adjustable wastegate, adjustable fuel pressure regulater,3 angle valve job, 8:1 compression with mild head porting, 65mm throttle body, power plate, shift kit, 8.5 rear with 3.42s



ive got a 97 twin turbo what should win?im in VA by the way

what is the difference between a regular grand nat and a gnx ?? just wondering. i'm clueless about those cars i just know they are like american supra's LOL

The GNX is a Special Edition Grand National... They are a bit more tuned and modded. There were very few of these made and they are quick, They also have Ladder Bar suspension to keep possitive traction under Hard acceleration. The guys car should be pretty damn quick, with what he has, but I don't know how it would compare to the Seven..

i think im screwed, your wrong about the 14.2 1/4 mile i just found a mag test that one ran 13.8 stock

i really think i screwed my self over this time if he wins he gets to keep a part of my car and i know what hes going to go after, my wing. guss ill be calling it off

wow.. hmmm.... LOL

That guys GN is probably a 11 second car at least, probably faster.

Popular Hot Rodding took a stock block GN with close to 200,000 miles on it, put some bolt ons and Kenny Dutweiler dyno tuned it to about 550 horsepower at the wheels, the stock turbo charger as well. The cars wernt ALL that heavy either, I think somewhere around 3300-3500 lbs or so.

GNs go VERY fast with some minor tuning.
