How many HP did your stock viper have?

[Matrix]

I´m interested in how many horsepower your stock viper have? Then with and without k&n, exhaust, high flow cats and so on...?

I think 435 rwhp has been about the starting point for a (new) stock engine ... it may go up a little after break-in.

My'04 dyno'd 442 rwhp and 482 lb ft of torque bone stock with about 2600 miles on it. Since then, I went with a DC computer upgrade and a light weight wheel/tire combo. I haven't had a chance to re-dyno yet, but my butt dyno tells me that it gained 30 to 40 rwhp.

I have the K&N, High flow cats, corsa, DC computer, 180 stat, light weight flywheel, 3.55s, sidewinder wheels and just dynoed at 500hp and 522tq at the wheels back in January.

93 octane and very aggressive break-in. I think it had around 600 miles when I dyno'ed it that time...

452 ~8k miles stock on DynoJet.
459 ~14k miles k&n on DynoJet.

Id say any were from 440-455 is about right. most people in the 430's are on the lower reading mustang dyno's..

Damn...You guys make my 99's bone stock 410 rwhp and 465 rwt SAE on the dynojet seem a lil limp wristed....Even with no cats and smooth tubes im only at 428 and 473...Need more mods just to be even with you stock guys from a roll...DAMMit
