supercharger hp numbers
Just bought a roush stage 1 (6 to 7 psi) non intercooled kit for my 2005 f150 5.4 3v. plus colder sparkplugs ,42 lb injectors ,high flow fuel pump (all getting installed in 2 weeks). For exhaust i got 1 3/4 obx longtubes with magnaflow muffler running 2 1/2 pipe all the way thru. Going to take it to very reputable Somewhat domestic only dyno / speed shop after install. Roush states that u get about 115 hp at the crank with kit. Now i know these trucks only have 300 hp to start with but after all said and done i was hoping to have more power than a new stock raptor. Buy the way truck in great shape only 76000 miles used mobil 1 synthetic for ever runs great. My question is if any body did mods comparable to mine and had a custom tune what were your numbers ?

12 Second Truck
Cograts on getting a super charger. The non intercooled Roush kit is usually good for about 330-350rwhp. Lots of variables there of course. Weight of wheels, type of dyno, elevation, fuel quality, etc. Btw be sure and gap the plugs at .032.
I personally run a Whipple supercharger. The last time I dyno'd was November of 2011. Made 475rwhp and 532rwtq at 12psi. I have made a few mods since then pushing well 500rwhp now.
