Is it just me, or does that torque curve on the
whipple charger look sick!? That alone has me really debating on whether to go with the whipple or the procharger... Probably whichever is more reliable and easy to service I guess?

I CAN say that it is CERTAINLY obvious on a test drive (Our experience on the dyno has proven the Roots/Screw to make more power in only the lowest 500-750 RPM by superimposing a Procharger graph so we can show them on TOP of each other and SEE. and THAT part of the powerband (SHIFTpoint or REV-Limit), goes away VERY quickly when Procharged). This thing is really savage on demand, however, when driven normally, has perfect manners, best thing yet is NO drop in Trip Fuel Economy. I will just have to moderate... LOL!
The best link I have to my experience... At least 2-300 RWHP GAINS depending on the system. Try knocking the ET off your stock GT by FOUR seconds... Procharger has a STRONG following, and they are responding with complely redesigned systems that are so complete, you need NO OTHER BOX or a dyno nearby!

Trucks, yes. 2 Valve PI heads, YES. even worse the 4.6 has a monstrous spider intake and an IMTV so it can switch between dual and SINGLE plane on demand. The 5.4 trucks get a single plane OE, and well, you know the Lightning cobra setup. INSTANT LINEAR POWER!
PROCHARGED 5-speed GT... (9 PSI tuner kit). WFO, but from a 5 roll in first, just singin the tires, then hitting 2nd and feeling a politely violent body stand. NICE stand UP, it pins me to the roof, and less than HALF THROTTLE in second... You can count on a POWERSLIDE to near redline. Too much smoke and noise for comfort in a small town, much less a WOT 2-3 shift that would have only brought me completely around...
(I am Remote this week, needed some adrenaline therapy and to see my baby girl Lauren).
Service? 10 min oil change performed at 11:00 PM of the nite I arrived. Piece of cake. Comin in, I was so wired I didn't sleep ANYway!
