Hi.
Had the car dynoed yesterday.
It's a 355, with 210/220, 480/480 at 112 cam. Match ported, gasket matched. Otherwise stock. Homemade 3" air intake (maf screens removed) open element breather,8mm Taylors, Busch plugs and TB by-pass.
The engine maxed hp. at about 3650 rpm.
Does anyone know why the hp. would start dropping so early? or what I would need to do to improve?
The numbers are what I expected, but not at that rpm.

 

A major spike at 4500rpm. Not sure, but think it is ignition.
BTW this is RWHP.

 

You should post this on the TECH/Engine board, might get more better responses. This is a street racing board, these guys don't know anything about engines, just how to brake the law. jk guys.

 

What heads, intake, headers are you using? I'd say you need more ign. too.

 

Thanks Mark, I do post on engine board.

ATOMonkey, I have stock match ported heads and gasket matched.
Future mods include ignition, AFPR and headers. I'm hoping these will help.
