10's on $5,000 ?

What I see as typical, for a reasonably well matched/sorted bracket car is....... the car will run about 90% of the corrected dyno hp...... if you’re racing in “reasonable” air.

500hp on the dyno...... shows 450hp on the calculator.

I have a few customers with bracket cars that run real close to right on the dyno hp number........ but typically it’s 90%........ and many times it’s quite a bit worse.
Which is usually the case for a combo that’s had any concessions made for street use.
