I recently purchased a 2000 SS Convertible. People ask me "how much horse power (rear wheel) does it have?" What would be an honest answer if it has the following modifications:

SLP Cold Air Induction
SLP High-Flow Air Box Lid
SLP Smooth Bellows
SLP Mass Air Flow Sensor
SLP Loudmouth Exhaust

Thanks!

 

auto = 310
m6 = 315


assuming the maf isn't messing up the A/F and robbing hp

 

It's m6 with 4.10s - What does a stock SS have? Is the 320 hp that I've seen on sites like autos.msn.com at the flywheel?

 

It varies from car to car. Go to a dyno and find out, or wait for a dyno day.

 

What would be a good ballpark? I think 315 is too conservative.

 

Yes, thats the factory rating at the crank. Ignore it because its way low. You probably are in the 315 to 325rwhp range.

 

A Stock SS has about 345-350 at the flywheel and just under 300 to the rear-wheels. You probably added close to 20 rear-wheel horsepower with your mods so I would guess you have about 320 @ the Rear-wheels and 370 @ the flywheel.

 

The numbers Teke gave you are about right.

 

realize the only hp (from a dyno standpoint) mods you have is a Lid and catback.

the maf may or may not be adding any power...particularly on a very near stock car.

the cai and bellows do nothing for hp

on the highway the cai may give a couple ponies...get the Austin scoop for it and make it a ram air and you'll be all set.

so figuring an m6 starting at 295-300hp + 5-7hp for the lid + 12-15hp for the loudmouth = 315-320hp

 

Ok -- sounds good! Thanks a lot for the detailed responses
