[pattrick02]

our cars are about 20 percent due to the awd system. what exactly is your exhaust set up? x pipe? resonated? cat back? downpipes?

[NorthShoreInnovation]

this dyno runs about 20-25%

[eadad]

did they over rate that things crank horsepower by 70 horsepower or something?

[superfast30]

The number quoted are at the wheels. Add 25 percent for drive line loss and you get the crank figure!

[eadad]

25% is a bit much tho dont you think. isnt it usally for most cars like 10 or 15 % ?

[superfast30]

15 percent is usually the figure for 2 wheel drive cars.
