I may be wrong, but I believe there was an SLP catback exhaust option available for the Camaro SS that brought the rating to 310 horsepower.

3" catback exhaust and "ram air" is what's credited for a 305hp rating. It probably was all due to the exhaust since the SLP 2OTL is known for being one of the best flowing catbacks out there.

I dunno.. something worked because the majority of f-bods back in the mid 90's in the DFW area were mild bolt-on or stock and I had no problem beating the majority of them when my car was stock.

some of the late 95's got the '96 dual cat exhaust (like my car) so some of the 95's are technically rated at 285..

ALL of the '95 A4 California Emissions cars had the '96-'97 dual-cat exhaust. May be the only time in history that a cali emissions car had a higher factory hp rating than the non-cali cars...

I too believe in the Fbody cars rating being lowered due to the Corvette.


I hate dyno numbers because of the M6-A4 difference.

How are you guys thinking the LT1 was underrated? The everyday LT1 F-Body ran high 13's and low 14's. Pretty much right where they should have with the power ratings they had. The SLP cars, WS6 included, ran better. Mine ran 13.50@103 when it was bone stock back in '96 at MIR. I was pulling 2-3mph more than the Z28's.

The 'Vette's were rated higher because of the better intake and exhaust.

LS1's on the other hand, were way underrated. LT1's not.

My experience makes me tend to agree with you. There will always be people with different experiences or just high hopes, so it's a debate that will rage on I'm sure.

assuming an 18% drive train loss you should dyno about 233whp, which is what most auto's dyno. i dont see how they are under-rated. if they were dynoing 270whp stock then yeah they'd be under-rated

my car with lt's, true duals, and homemade cai (no tune) put down 268whp and 300ft/lbs
