went to the dyno yesturday - graph posted

[efuehrin]

Well I went to the dyno yesturday to see where I'm at before I put the supercharger on.

See below for my modds list.

The guy told me that I am probabaly loosing 30-35% in the drive train so my flywheel HP numbers should be somewhere in this range.

ESTIMATED HP AT FLYWHEEL / Drivetrain loss
267 / 25%
269 / 26%
271 / 27%
274 / 28%
276 / 29%
278 / 30%
280 / 31%
282 / 32%
284 / 33%
286 / 34%
289 / 35%
291 / 36%
293 / 37%
295 / 38%
297 / 39%
299 / 40%


I"m pretty happy with this with my 38's on.

I'm hoping for 320 at least with the Kenne Bell 2.2 on. that's at 6-8# boost.

I have the exact same truck, Ive been wondering what kinda power it would put out, now I know why my brother Hemi blows me out off the road.

I'd hate to see a dyno of my 4.6 F150 after seeing those numbers!

I wonder if I put some Comp 270 cams, Cut the cats off and put ona Free flowing muffler if I could get around the 270rwhp range, My buddy has these cams in his 4.6 and is wanting to do customs so i could pick them up cheap, Ive already got a SCT 7 way chip and a CAI. With longtubes, o/r hpipe, magnaflows, RPM intake plenum and 75mm TB and he dynoed at 269rwhp.
