Dyno'd " Project Sucker Punch"

[MrHorsepowerLSx]

Power is torque multiplied by angular speed. Lower gearing will lower the angular speed, therefore lowering the recorded power. I'm sure there are many more variables in your case, but this is what I have learned while getting my engineering degree. I don't have the degree yet, so take my words with a grain of salt. Lol

As I mentioned earlier the tuner had stated that a sime gear change from I.E. 4:10 to 4:56. On a similar setup was roughly 45-55 RWHP, I asked the tuner to " explain " how tha worked but " your " words made more sense lol he stated something similar to that, but I learn better by reading not just listening lol..... Kerrige I think we were spinning it to 6400, 6600 maybe..... I cannot upload the dyno runs from my phone, but I can text them through PM, I took the run of the screen for data purposes, not just watch the trucks me noise going no where, text me your numbers and I will send the vid to anyone that wants to see it

A 5x11" magnaflow will do you good. Or as its better known the 22" big body magnaflow. Quiet on cruise and loud at wot.

Do you have one of these mufflers on your truck?? I have been looking into changing my truck over to a magnaflow system.

Yup. Heres a link to kinda see what it sounds like.

Actually it might not help because its dumped before the axle. On my brothers boosted 5.3 the same muffler is quiet enough to hear the turbo spool at full throttle with the windows closed lol.

Sounds good what are your cam specs? ( PM them i you would )

Cam specs are TSP 220/581/112. Its a little big for a 4.8 even with a 3200 stall it could use a 3600 or a 4000 stall because it starts to really shine at about 3800 rpm.

Do you have any driving vids with muffler on it?
