Most dyno operators won't pull a car more then 3-400rpm past peak for whatever reason. The Dyno operator seen the 6100rpm peak and the power start to slightly taper off by 6400rpm and let out. Likely because it's not their car and if the OP was there and requested it, then perhaps he would of run it out.
You think a dyno guy can pull and determine when the engine makes peak and shut off with-in fractions of a second? LOL that is funny. The guy had just shut off too soon period, he monitored NOTHING other than RPM. He did not "see 6100 rpm peak". I personally have run many cars on a dyno.. how many have you run? Right... thought so.

As you were insistent the the runs were OK and already showed peak HP... yawn.. the run was not OK and left a good bit of the powercurve off the table. But I do agree for dyno racers it was fine.

Agree, it was your typical off the cuff naysayer... but please continue.

Cause he messed up... nuff said.

Depended on how flat the peak is, this car is pretty flat (1%) with a few HP from 6100 to 6450 RPM, and who knows how flat it would be till 7000 RPM? I posted another near identical Vette setup that shows power near flat from 6000 to 7000 rpm. Your making like this is a VTEC Integra that really does have a "peak" HP. I'm 100% sure the car should be shifted at the max RPM the OP is comfortable with on the stock short block. There is 90 HP difference in the next gear 6700 rpm shift vs 7200 shift. So you can toss around your fictional 6100 rpm peak and general run of thumb, all you want. Clearly the engine makes WAY more HP in the next gear when it is shifted at the highest RPM the OP is comfortable with on the stock short block.

Me? I just mused that a large cam dyno where the operator could have lifted as early as 6350, should have been run longer.

Yawn, sorry I passed the bolt-on a supercharger stage years ago.

No "goal post" were moved. You basically are wrong once again... nothing new.
