Piston windowed vs compression vs rpm...

I dont check the rpm on the dyno graph, but all rpm i told it's on my trail tech vapor computer..

 

but if it's easy for you to answear my question if i told:

well plainly put it is not going to increase your peak rpms by 1,000 to have windowed pistons over a typical prolite and the best explanation for why your vapor gauge is reading high numbers must be that it is simply innacurate and Not showing you the correct readings in the display

But, if i only rev 9000rpm with T5, i rev 9200rpm with shearer?, or it's possible to rev 11500 with shearer?

[flotek]

yes its totlaly possible for a drag port the right mods and shearers to hit 11,500 rpms

...problem is its not happening with toomey T5 pipes ,the sheaerers will often outrev them by well over 1,500 rpms or more , id say your gauge is inaccurate... even to itself

The tach on the vapor is a joke. Mine also used to show peaks of over 12k with stock ports and t5s. Just doesnt work for shit.

I hit 10500 rpm with my drag ported 4 mill stroker (CPI Pipes) with a missed shift :biggrin: (Vapor Recorded)

 

Dan from Patriot Racing said that my engine should build Max HP at 9200-9400 rpm. If you go past where max hp is made your slowing down and over reving your engine.

You might try adjusting how many wraps around a the plug wire you have. Also make sure your running BR8ES instead of B8ES. The non resistor B8ES plugs really mess with the vapor.
