Somebody probably already asked this and got an answer. I am going to ask again because I really dont want to go threw 374 pages of forum to find out. How do you guys like the pettit supercharger? what kind of performance gains are we talking about. They claim 275-300 hp. Id rather hear about your experiences and your opinions on the pro's and con's.

You don't want to read up on a possible $7,000.00 + investment? That's smart.

A valid point. Tho for the last part of being spoon fed. I wouldn't agree. Especially since I have been on this forum looking for specs opinions and information for days and all I seem to find is people talking about having a bbq or who on the forum actually has a super charger from pettit. I don't see how it is unreasonable to give a quick simple opinion on the product you bought. Especially when in the amount of time it took you to flame me you could have given a simple "hey its great ive had it for so long and i saw a 70hp gain I highly recommend it.

In the time it took you to make your posts you could have skimmed through several pages of this thread and found the data you seek. Or you could have just called Pettit and gotten the scoupe............

Its worth it. Like any FI package you have to do more that just purchase the kit and install. Supporting mods have to be done--but it really transforms the car.
I checked the mechanical movement of my ssv last night ( gets dark at 6pm now--i hate it) during the 40mph wind gusts we were having. The action was smooth. The vacuum lines where intact. So now I will just have to check the signal. I am letting the wind die down first

To verify that the SSV is working all you do is :
start the car
have someone turn it off while you watch the SSV actuator
It will do a test actuation .
No test actuation =no worky . Action of the valve is a quick on/off without any hesitation or jerking .
an even better way is to do two logs :
one with SSV connected
one with ssv disconnected
You should clearly see a difference in MAF (starting around 4000rpm) between the two logs .
No difference = no worky .

at the risk of fueling the flames of supercharger fanboi hatred, the cons are that small displacement, high rpm engines and superchargers do not a good couple make. First, the supposed lowend boost of an SC setup is totally false, it is just the opposite with today's turbo technology. Second, for the same engine stress level that you make an extra 70 HP on a Renesis with an SC equates to about an extra 110 HP with a turbo setup because of the power drain required to spin the SC at high speed. Further, with a high rpm engine then the higher you spin the engine the more power eaten up by the SC and in turn the more stress load that is placed on the engine for any given power increase at the rear wheels. The higher stress load is not just on the engine, but also all the supporting equipment such as radiator, oil coolers, exhaust sizing etc. They are also a lot harder to keep quiet since there is nothing damping the sound level coming directly out of the engine unimpeded into a high flow exhaust system.
The pro is that you can't just turn up the boost at the twist of a ****, which is where most turbo owners discover their destiny to fail.

lol----tell us something we dont know. So my 292 rwhp at 7 psi boost would be 332 with a turbo?
Woohoo!
With the damage I have caused with my simple constant boost sc kit --just think of all the stuff i could have done with a turbo set up with all those controls!
All joking aside--turbos get more power to the rear wheels-everything being equal package wise. No argument here.
Oh--is the turbo guaranteed for 100K miles?

WELL GUESS THE HELL WHAT!????
My SSV was NOT working. Good call Brettus. I owe you one.
Ok I trouble shot the thing and I found that the vacuum canister solenoid was not working--actually one of the last things I expected. So being I had two more available on that canister ( no vdi etc) i used another and it works fine now.
Yes----- my under the curve power has come back, my a/f's really seem unaffected after a couple of drive cycles but I didnt go over 7K and with only about 40% throttle. I did not want to put any high load on the engine since I only have pump gas in it.
I will check the trims and drop Steve Kan a line.
It never threw a ssv code at all--never.
I do get the p2004 at times, but that must be from the pcm seeing a little higher voltage as the valves work well and the checks are normal?
Thanks again guys!

Did you find out all this info from your experiences? I haven't heard of any blower vs turbo racing, id imagine at the 1/4 but not on a track. Denny, you been on the track with any turbo 8s??
