Right now im running what id call your basic 416. high Comp Piston, cam shaft and and exhaust. Im running a 11:1 compression, TC cam shaft ( 926 ) and an FMF pc4 slip on. About how many ponies you think im pullin? assuming the jetting is all right. How much do u think porting would add to it, and throw in the carb later down the road. IM just thinking of how much power can i get out of my 416. ive seen them push a littlte over 40hp before NOS. but im sure it was running a 12.5 compression piston, stronger rod which adds more comp, major porting etc. but for the average rider/racer who has ur basic 416 about how much are we looking at?

im thinking im around 34 at peak power..

I dunno I heard of won that ran close t0 50 before it blew on the dyno, theres a post about it with a chart.

I am hoping to get close to 40 from mine when its done. but i will have a few more mods then you.

I know a few like yours on the site dyno 33-35.

Mine dynoed in at 33.5 RWHP before I gutted my airbox and added a K&N. Which did make a noticeable improvement. I'm guessing mine's around 35 RWHP now. My mods are in my signature.
