i have a 94 gsr with 114k miles, just curious what you people think i will put down before i get it dynoed this weekend.

aem CAI with bypass valve
dc 4-1 header
full greddy cat back exhuast
and BLOX Intake manifold

i also have the rears and passenger seat removed as well as the spare tire and jack if that matters

just seein what you guys think and if its close to what i put down

These items will not affect the dyno. If you remove inertia from the drivetrain, it will show as a HP increase due to the testing method.

147whp

I was just wondering what exactly is the inertia from the drivetrain?

OMG man if you gut out the dash and carpet it will give you a good 5whp so you should be around 190whp depending on how good your headers are headering

Wheels, tires, brake rotors, flywheel, pistons, rods, crankshaft, camshafts, pullies, etc. Basically anything that rotates in the drivetrain during the test is contributing rotational inertia. Since the test is accelerating a drum, this reduced inertia incorrectly shows as a WHP increase.

 

Please do not waste your time and money by putting your basically stock gsr on a dyno, unless you are tuning it or something. I would guess you will make about 170 +/- whp. Good luck with your project.

no way probly in the ball park of 160

 

I believe Dogginator has the most accurate estimate. Based on a normal 15% drivetrain loss, you'd be looking at 143-145 whp. The modifications you have listed might yield 5-10 flywheel horsepower over stock...which might yield 1-2 whp on the dyno.

 

Well 170 is kind of high...prolly more like 160 +/- without a flywheel or lighter crank pulley...

crank pulley

 

yeah im guessing about 145-150 i have a pretty much stock gsr just a few mods and i pulled 142.

 

i'm guessing under 140, 135 if you're on cali gas.

If you have a tune up and your engine is in good working condition a gsr WILL make at least 145 whp with no mods. It has been proven time and time again...his mods will have to make 15 whp especially on top.

lol since when do basic bolt-ons with no tuning make 15 whp?

Maybe this magazine knows nothing...butttttttt, what do you think? Well maybe my number of 160 whp was off by a whp. Oh well..hahahahaha

And that's without the intake manifold...

 

Ive seen 165whp on a gsr with just i/h/e so theres a lot of variables. Ive never seen a healthy stock gsr dyno under 140whp and in most cases theyre at least in the 145whp range in good condition.
