Actually...... on legal tires, Harry’s best was in the 11.50’s, at MIR on a pretty good day.

However, I seem to recall him telling me it went 7.10-7.15 in the 1/8 on small slicks.

With sticky tires you could run mid-11’s pretty easy with 500ft/lbs, 475hp..... Std corrected off the dyno...... in a 3700lb car at a track that’s less than 1000ft elevation, in “reasonable” air.

How much you lose with the bias plies will depend on how well you get that part sorted out.

“If it were me”, I’d pick up another intake if you don’t have one....... do a back to back test against the stock one on the chassis dyno.
