I have an integra with an ls tranny and a b16 engine. I am buying a supercharger and want to know what to expect. Looking to boost around 8 or 9 pounds. Is water injection necessary? Can i run that much boost without it and just the upgraded pump? What kind of 1/4 mile times am I looking at? Thanks in advance for the responses!

 

Is water injection necessary: I don't know about this one. I've heard very mixed reviews on water injection.

Can I run that much boost without (water injection): Yes. There are a bunch of people doing that and they don't seem to have any problems.

Can I run that much boost without an upgraded fuel pump: No. I even at 6psi the fuel pump struggles.

As for the amount of power to expect...it's hard to say. I got an extra 40whp and 35 wtq out of the stock kit for a B18C1. At 8 or 9 pounds, I'd say 50-55whp??? Not too sure.

 

consider methanol injection....
don't know much about it, except it works
