Superchargers

[TonyLuch7007]

ok, so i had been doing alot of surfing in the net and came across a supercharger in a website called; moddbox.com
Does anyone have any input on this supercharger? is it any good?

Curious, because this supercharger is for a 4.0L V6 / 245 engine.

they sell an install kit... you still have to locate a tbird supercoupe m90 roots blower... the basic kit of 3.5psi is a useless upgrade in my opinion... anything less than 7-8 psi is not enough to make a shock and awe experience and I really dont know what the bottom end of a stock 4.0 can handle.... basic rule is 11hp per 1 psi so I know I dont think 30hp is worth $2000... you can add a 50hp dry shot for 500 if you are looking for cheap power adder well that is until you fill the bottle 5 times and you get sick of it... I wish mine was a 4.6l but I would never try to make the 4.0l hang because it prolly wont

cost per rwhp

For my street vehicle my estimating decision criteria is $100 per rwhp. My custom exhaust system cost around $1K and I realized a gain of about 10 rwhp. My M90 installation gained about 60 rwhp with 6 psi of boost and probably cost around $3,500. As I recall Moddbox is a Canadian outfit. Their product looks decent on their website but I don't remember any forum members who have installed one of the kits yet.
