I know it is complicated to figure out but I would like to know how much boost you guys think this will make. I have Kooks long tubes 1 7/8", EPS cam 226/234 .598/.612 114LSA, stock heads, stock intake, and corsa catback.

Its a D1SC 8 rib, procharger spec'ed a 4.38" blower pulley. I requested to between 8-9psi range.

What do you guys think will I be close. Some delays in the dyno session it wont hit the rollers until Tuesday now. The tuner thinks it might be a bit large I guess we will find out for sure soon. Interested in your opinions.

That blower pulley may be too big. I would look at a 4 - 3.85" size. Edit, I was assuming a 7.25 crank.

That sucks, I hope procharger did their math right. I don't have a lot of time before the build needs completed. I plan on meeting some friends on power tour.

Anyone else have an opinion or experiance with a similar set up?

On my old setup I had the same headers, about the same cam, stock 241 heads, Fast 90 intake, same head unit with a 4.25 pulley and made 13lbs Thanks jeff

You guys should mention your crank pulley size as well.

Your right mines 7.65 thanks jeff

I have the 7.65 crank pulley.

Well my pulley is larger so it will spin the head unit slower. Your pulley was the next size smaller compared to mine. I hope that gets it down to about 9psi, I dont want my stock engine to RIP to quickly. I am assuming yours didn't like the 13psi so well so it is now dead!

When I ordered mine it was supposed to be only 7lbs and that was going to be all the power I ever wanted. lol

Well not really I ended up putting it on 15lbs and my tranny would not shift into 2nd at Zmax and it lifted the head but it ran on 13lbs forever

If you are worried about it making too much boost, can you simply lower your rev limiter to say 6000rpm to keep the boost pressure down? Most of the procharged dyno's I've seen only rev to 6400-6500rpm where the NA heads/cam guys go to 7000 rpm.
