I won't be doing mine. I don't race and 425 hp. is more than enough power to get me in trouble. Besides, I live in NJ- the most densely populated state in the U.S. The roads are very congested and I rarely get a chance to air it out.
A friend of mine has a 2009 Hemi orange SRT, he had a Kenny bell super Charger installed on it. All I can say is that I named his car the beast... it definitely had some force behind it and would plant your ass firmly in the seat on launch. Sent from my iPad using Tapatalk
On factory internals with only long tubes, intake and cat back exhaust the 5.7 produces 550 hp at the crank with the Magnuson which includes the Magnuson tune. It's not a particularly difficult DIY with the step-by-step Magnuson provides online with pics.
Anybody know much about the "torque storm" brand of superchargers? As in, ever install one or know someone how has? They are shockingly cheaper than the usual brands, so I am trying to figure out why. They advertise between 3K and 3.75K. https://torqstorm.com/product/supercharger_kit_hemi_5-7/
The kit doesn't include a tune which will be necessary for the engine to operate (you'll have to purchase a tune device to read the stock tune and find a pro tuner willing to work with you to calibrate). Doesn't include an intercooler (required) and the factory coolant tank can't be used. I'd have no confidence going forward on a DIY application from the description in the link and would be curious to learn what the speed shops doing this work know about the kit and the support behind it. Unless you're 1badmofo automotive tech specialist yourself?
Turbos make more power with less fuel consumption. Put a super-low-RPM cam in it and let the turbos spool early and then carry a nice torque curve on up. Unlike a supercharger, turbos don't cost much power when the throttles are shut.
