Why Is It That When I Hit 7,800 Rpm
#1
mods: removed top off intake, aftermarket drop in air filter, tb mod, port matched manifolds, removed 5th and 6th port sleeves, advanced ignition timing, 2.5 inch exhaust single exit(stock manifold). maybe some other things i forgot,
when i accelerate hard everything is all good until i hit 7,800rpm, it feels like my car hits a brick wall, it starts backfiring and bucking, it wont go past 7800, WHY???
am i hitting fuel cut??? if so why? do i have fuel cut? is it ignition?
oh all emisions are gone a/c p/s air pump, acv, rats nest, all gone, also omp is gone, premix exclusevly

Is there a neccessity to rev the engine up that high? Isn't max horse power at 6,500? Wouldn't it be slower if you over rev it like that?
