Anyone know approx how much Horsepower the JRSC puts out for the Civic Si??
Just bought a car with a SC and the guy never had it dyno'd. Says the SC is only set at 4.5-5 psi.
Any idea how much higher i could go and not worry abot the engine internals?

 

I would have said approx. 50% of your HP, but at 5psi??? My supercharger is set to 7.5 lbs. from the warehouse, so i'd imagine you could go a little higher.

its probably right around 200 hp... what year Si?

 

it is an 02 SI. How do you change the boost on the supercharger?

Also, Do you have new headers on yours? What kind and did you notice a difference when you put it on?

 

change the boost with smaller pullies. the smaller u go the more boost u get

 

Where do you buy the pullies, and when you do get a new one where would you get a belt to fit the new size? I have not seen any differrent size pullies for the 02-04 Civic Si yet.

 

jackson racing has a boost upgrade kit with the pulley, belt and other goodies.
