What does a basic bolt-ons GN dyno?

[Ross]

I'm just wondering how much rwhp the average 86/87 GN/Turbo Regal w/ basic bolt-ons will put down.

Basic bolt-ons -
Alky chip, alcohol injection, translator +, hotwired 340, adj fpr, bluetops, catback exhaust, maf pipe, k&n air filter, adj. wastegate set at 20 psi of boost.

All else pretty much stock.

Basically, I'm wondering what my car would dyno.

I'd send a copy of mine but I can't figure out how to operate the damn scanner, anyway max hp-248.6 /tq-407.8. 36# injectors,open filter,tru ex chip?, 0ver 100k miles. Since then it's been freshened up,but still mostly stock. Hope this helps.

You have close to what I have. Probably about 350hp and 450tq at the flywheel

Dyno'd my 87GN with stock turbo at 17psi, stock intercooler, injectors, 92 Thrasher chip, 92 octane gas resulted in 271HP/413TQ at the rear wheels. Ran mid 13's at 101mph at the track.

do you know what MPH you car does in the .25? (and what it weighs?)

The best it has ever run was 12.41 @ 109mph.
I'd probably be interested in "street trim" dyno numbers. It has run a best of 13.0 @ 105mph in street trim.

Thanks guys. Keep them coming.

My GN had similar mods as yours, same boost, parts, etc... I did 291HP/446TQ. It ran 104 MPH, 12's.

my street trim dyno numbers were
330HP/390TQ with 19psi on a TE44 and FM with 36lb inj and 18* street chip
best time slips in this trim were 12.90s at 106ish on street tires

Open Dump, Red 93 Chip, and alky ~19lbs boost my car did 280 RWHP and 420 Ft/Lbs.

I even still had the stock air intake on it, stock fuel pump, and regulator too. I was living dangerously. I'm going to be dynoing my new setup hopefully soon.

Thanks guys. All those numbers listed above look pretty promising for me. I'd be thrilled if I could get 300rwhp and over 400ft/lbs.
