I know the 1999 Z-28's had 305HP at the crank stock, but what did the 1999 SS's have stock? As well as the 2000 SS?

Thanx

 

They were just rated slightly higher. The SS's might dyno a bit better if they were equipped with certain things like an exhaust package, or so. Otherwise, they're just rated higher, and are just as fast as a Z28

 

Oh Ok .... I just found that they are rated 320HP. But equally fast ok.

 

What he means is that both motors are equally underrated by GM, and both z28s and SSs will dyno 350hp at the crank if you were to pull the motor out of the car and stick it on an engine dyno. F-Bodies (Camaros and their Firebird twins) typically dyno right around the same as a 97-04 c5 Corvette.

 

yup, but the loss is in the drivetrain...so you're really feeling about 290-300 at the wheels

 

Yeah, but he was asking what the hp levels were at the crank, not the ground.

 

oohh sory =(. Anyway, why did GM underrate the crank HP so low?

 

so it wouldn't take sales away from the Corvette. Who would buy a 350HP corvette if they could get a 350HP Camaro? (that's the reasoning mainly)

might also be for insurance reasons, etc.

 

yeah, that extra 30 hp makes it hurt just a little less when they assrape you on a camaro :P

 

see sig

 

wow so with just a lid you had 317HP at the wheels..... thats impressive

 

What kind of dyno??? Makes a huge difference...
I've seen anywhere from 280s to 310s rwhp on stock LS1 f-bodies of those years on a dynojet. Each car is different as is the outside factors (temp, humidity, etc) and so is each dyno. You can't really compare runs made from one day to the next let alone different cars on different dynos on different days strung across the country.

Dyno numbers mean little seeing how I've outran cars that made more power on the dyno.

 

This may be true, but I don't remember the last time I have seen a car dyno where this isn't accounted for. All dyno results are typically standardized with the SAE correction factor, although some dyno operators still use the STD correction factor.

 

You never know what numbers people will report on boards. They very well may be uncorrected.

 

My buddies 00 SS m6 dynoed 322rwhp 334ft lb's with slp lid. If you didn't know 01-02 F-Bodies got a smaller cam,LS6 intake some other changes. My 01 SS bone stock right down to the paper air filter 306.7hp 327.2ft lbs of torque. I have the dyno graph somewhere
