what do you guys think im pushing for hp with my few not worth mentioning mods.....k&n, airfoil, no cat, flowmaster 80 series.....i know mine stock is 275, what do think im pushing now, do you think it increased by a bit. am i close to 300 hp?

 

I'd say around 280ish.

 

stock the car is only 245RWHP maybe 250RWHP so you might be at 265RWHP

sorry

if you dynoed thecar stock at 275rwhp then you have a freak

 

I think he's talking about at the flywheel

 

Your car was rated from the factory with 275 net hp at the crankshaft (brake horse power). Your actual rear wheel hp will be considerable less. Rear wheel hp is what everybody talks about. With out opening a huge debate on which model of chassis dyno is most accurate. You truly would need to put your car on a chassis dyno to figure rwhp. That being said there are some math formulas out there that take the race weight of your car and 1/4 mile et and/or 1/4 mile trap speed to figure estimated rwhp. Try not to get caught up in adding all advertised aftermarket component horse power increases. Example: CAI =10hp, Catback = 15hp etc. etc. The bottom line is what your car will do on the track. Besides the track is the most fun anyway

 

You may have 240RWHP with the auto!

 

thats kinda modest. I think he has more than that.

 

thats a stock dyno on average.

 

I would say around 285-290 at the crankshaft, and around 245 at the rear wheels assuming 15% drivetrain loss.

 

My stock SS dyno'd like 252 rwhp with a bad opti so I think 240-250 is in the ballpark. Maybe another 8-10 with a CAI. Keep up the mods and dyno to know what you have for sure. Guessing at rwhp is like picking a niddle in the haw stack

 

Look at his mods! An air foil, K&N filer, and a flowmaster muffler. Those arent gonna do anything great for your numbers. If stock crank hp was 275, he may now have 282 or so!

Now unless the K&N is a CAI or just a filter he may have about 287 now!

 

i agree.

i was just saying that 240 245 was on the average.

287 maybe at the crack.

 

I put down the numbers in the sig with the mods in the sig...basically stock with free mods, CAI and Cutout


But then again I have a manual...

 

A manual is gonna make better numbers on the dyno. Did you have the cutout open when you dynoed the car? That shouldve helped a good bit.

 

i actually never dyno'd the car, and i wasn't talking about rwhp, i was just comparing the stock hp from factory at the crank, but i was told that maybe taking out my catalytic converter was good for approx 10 hp, maybe the rest was good for 5 i believe.
also i was wondering if the 96 camaros came from factory with 285 hp just because they went to dual catalytic converters, i think taking mine totally out should count for something perhaps, i hope anyways.
