I just hope it stays consistent, I'm thinking kyle might have a boost leak somewhere.....he should be seeing more....but you never know....
I'm probably going to go with either a 3.4" or a 3.2" I will be talking to scott on monday more about it.....

I would talk to scott a lot more and tell him exactly what you are running. That might be a bit hard with how quick he talks but make sure he knows that you are running a 370 with some great flowing heads. Your small cam might actually help you with the boost you see.
I agree Kyle might have a boost leak. All my clamps were loose and I posted that in the update thread. I went over everything a milion times on my ATI set up to make sure everything was right. Too bad I forgot to fill the ATF huh
I might go back to a mech boost gauge because this digi only tells you high and lo, it doesn't show if the belt is slipping like my old mech gauge did(needle hovering then sinking)
I hope he posts up some more info for us to see.
But be sure to talk to scott and let us know what he said. I pm'ed on fri night to ask them if I should be seeing this much boost....I am more freaked about that then anyone else could be.

Yea, we talked briefly before, but I'll get more into detail about the motor......
I plan on throwing a griffin on the car if all goes well.......that might run me into fuel problems though......

i know i hardly post here, except only to fugg with kyle(dont worry kyle, i wont fugg with you today_). whats the max psi the ATI is setup for?
i am just asking because i have done the blower thing in the past and was disappointed with it. thats when i decided to go nitrous. but thats another story. i am interested in this tread so thanks in advance.

I know SD's chevelle is putting down over 900 to the wheels with a D-1SC, I'm not sure of others out there who are putting it to the real test....
As soon as I get my pulleys I will put it to the real test

Thanks man......... you know im bumbed and almost ready to go the same way as you................ time will tell....... i dont really know the max someone has seen with this kit..... im sapposivley spinning mine at 51,000 rpms.......... 2 above i was before and seeing 11 psi before........ 7 now on the new motor....... steve called me on the way back and he told me about the little trouble he was having........ how much longer you got till yours is done?? Maybe i MIGHT go with a 3.2" blower pulley BUT i dont know........

Here is a few pics of the inserts in my tips...
It goes from 2.5in pipe to a 5/8 inch restrictor(opening on insert) with 13 pencil sized holes around the perimeter. I have one on each tip.

Damn Jeremy, those things are uuuugly.....
With Kyle's pulley combo he SHOULD for SURE be seeing more than 7psi.....if not then the belt is slipping or there is a boost leak.......with a 7.25" crank pulley and a 3.7" pulley he should be around 13-14psi at least.....I was setting mine up to max out the D-1SC blower and that is with a 3.2" blower pulley....
But.....
When I saw Jeremy make 16.2psi at 7900 ft, that had me thinking on what that would turn into at sea level, and he has the same pulley combo as kyle....
I'm still deciding on 3.2" or 3.4" either will put the D-1SC close to MAX impeller speeds...

I was thinking that route........ Everyone of my friends want me to give up on this blower setup............. I have almost 6K in just the blower alone...... i would like to see what this kit is capable of, but i believe it was never designed to make the power we are wanting from it........ if you are wanting 7-8 psi of boost and about 440-460 rwhp on a stock motor and be happy with it this kit is for you....... im not.... i am wanting to see what others see and do first befor ei just totaly give up.........
