Dyno test

Incredible power AND torque! Interesting how the base horse power is @12% lower than posted figures. I could see 4-6% but not 12%?

What's the cost? and what is the "typical" install price?

What posted numbers? Were they numbers from a Dynojet? If so then you should expect them to be higher than these numbers from a mustang dyno.

I would really like to know what a typ installation w/ dyno time would run. I live on the south shore (MA) so you guys would be the logical choice.

thanks,

By posted figures I'm refering to the GM's 400hp/400lb/ft of torque. Like I said I'm sure they're "biased" more towards the 400 mark, but I wouldn't expect such low stock dyno figures.

The stock horsepower and torque was at the wheels and therefore high not low.

I would say 356rwhp is pretty darn good for a stock 05. But still, if both runs were on the same equipment, I would think that that's more important to know, rather than what type of dyno was used. Just my 2 cents.

Arent the stcko numbers at flywheel anyways which would be less at the wheels if calculate the loss through the drivetrain.

Something is definitely wrong with the base numbers. But first remember "base" does not mean "stock". Base is just the first run that is being compared to all others runs after. If 356.2 rwhp was stock that's showing just an 11% drivetrain loss. 11% is kinda low! And 317.5 on the rwtq is just over 21% drivetrain loss. 21% is definitely high! 11% and 21% drivetrain loss on the same run Something is truly wrong with this info.

torque figures

I'm no expert but I just thought base hp at the fly wheel would've been higher. All-be-it the super charger really kicked it up! Impressive.
