Re: L98 Supercharged

I can tell you true numbers in a month. I put it on last year and have had nothing but expensive upgrades (i.e. injectors, cam, fuel pump, ect) and I still have the injectors and fuel pump needing to be installed.. But at 30mph I can floor the pedal and sit in that spot spiining rubber for a second on the 19lb stock injectors and stock pump. If I were a guessing man"(dont quote me) Id say between 100-125hp easily

Id buy one again if I had the money.. Its worth it

Re: L98 Supercharged

if i buy a car with a supercharger already on it what should i expect? is it just going to beat the crap out of the motor. not looking to buy a nightmare or a money pit. also it has a paxton supercharger on it which has been discontinued - so where do i get belts?

Re: L98 Supercharged

Depends on how it was driven and if it waput together right and not half assed. If you need belts click on that link above and call that number and ask for craig. He can get anything for the discontinued paxtons.
