supercharger is still spooling just as much as long as the crank is spinning at a given rpm... im not exactly sure but im guessing it bleeds the other 6psi because of a throttle vacuum line?

He has a centrifugal blower, there's nothing to bleed because it only produces 12psi at higher rpms near redline

and i don't see a problem running 12 psi on the XB motor every once in a while. but i would have to agree, forged internals are well worth the money. 12psi all day, everyday would kill our motor very fast! is anyone running a FMIC? its even harder on the motor with out one. nothings worse than forcing HOT air into a N/A motor!

as long as that cranks is turning that blower there is postive pressure, because its centrifugal the pressure builds with the rpms unlike a twin screw which has the same pressure at whatever rpm (i think)

Man, i feel like a total idiot. For some reason i was thinking he had a tubo. Of course the s/c will have boost because its belt drivin so you are right... if the crank is turning, so is the s/c!

Now a turbo is a diffrent story. I own a 97 Eclipse GSX, and i built this baby from the ground up. while vruising at highway speeds, a turbo is not in boost.

i didn't mean to jump in like king ____. sorry for the confusion.... i thought we were talking turbos

Simplyscion....if thats your ride, that is a nice ___ set up. However, i'm not digging the accordian looking pipe up top. looks tacky as hell. is there any way to swap that for a hard pipe?

Im thinking about getting somethin bent up but its gonna be a pain in the a$$ cause the pipe would have soo many bends in it.

Ok... Why is it that everyone that does these HUGE posts, are always the ones that are N/A? I find that to be rather funny.... I am up to 5-7psi daily depending on how I feel.

As for forged internals, the factory rods ARE forged. If you dont believe me, stop by and look at the one I have in my hands.

As for the not making boost at a cruising speed, that is correct with a turbo. At constant speed, you are NOT making any boost. You are in vacuum.

And thats only running it conservatively...they can be pushed a lil more w/ the right settings. Im sure that most of these people that threw a rod were running unsafely lean at the point of rod failure.

just run 7 psi but then again sometimes 7 might be to much it all depends on the tunning i would recomend using a hks fcon vpro or something to that extent the better you can control everything the more reliable everything becomes

i have the same set up as matchbox, i run 12 psi daily.
have been doing so for about year with no problems (except a burnt out clutch).
12 psi is more like it, the other guy was saying 6psi max
if I can run 30 psi on a stock neon motor im sure this motor can handle 12psi daily
thanks for the info guys, but your all running small turbo units, anyone running something with some high cfm numbers
I dont know whos running 30 psi on a stock neon motor but i call bs..... now if you are talking a srt4 motor thats a totally diff motor then the 2.0L sohc and dohc.... the srt has 8.1:1 compression instead of the stock 9.8:1 on the 2.0L and the internals are alot stronger

i run 8 psi all day evry day, and anyone from this area can verify i beat the hell out of my car. On the track i have done two full passes at 12psi, but i was HEAVILY overfueling the motor and bogging to the point where my 60' were in the 2.5 range lol. (a/f gauge wasnt responding correctly and i programmed my neo extra rich to be safe. I have since then tuned my vehicle a little further and will be running tomorow at Lebanon Valley. If i can, i will try and get someone to tape a few full passes.

Are those 12psi on a blower or a turbo?? Im pretty sure the engine will hold up to 12psi on a blower, but not so sure about a turbo. Alot of people claim to be pushing 10psi plus on a turbo, but i just don't think its possible. Im going to be running a GT25R at 7psi, which hopefully (with correct tuning) will put me at 130whp (i hope).

My lord!! There is so much misinformation and myth in this thread that it's sickening!!

I guess having a boosted Civic for the last 3-4 years has taught me a lot. I suggest some of you people do some TECHNICAL reading before basing your opinion on he-said, she-said info.
