What upper pulleys are you running with the 8 inch lower to get what amount of boost:tu:

2.75 and got about 10 with heads, exhaust and cam should be around 13 on a stock truck.

Hey Ray,
What heads do you have. I have the next sizes up from yours and only see about 7.5 # @ 5400rpms!!

I have a good set of heads and ported upper,but no cam.

thanks Raymond the tuner is working great I love it :tu: glad I didn't give up.

Raymond, what engine RPM was that at? (I'm trying to see how fast you were spinning that blower to get that kind of boost with heads/cam/exhaust, since that is what I am planning, too.) I have a feeling I might need to trade my S-Trim in on a YS to pull the kind of boost I am wanting.

Thanks!

Hey guys, that was on the old motor GT-40Y heads and the Lunati .535/.535 cam, Hooker headers, off road pipe and 2 1/2 exhaust.

Shift points were 58-5900 RPM.

I had a 2.5 pulley I was going to use, but then the D-1 came along and

Oh and the heads and lower intake were ported, but nothing spectacular.

Good deal Justin !!

Damn Motorola processors

Hi Terry, you've got a T-trim right ? I wonder if it needs to be spun up faster ? Do you have the 2.75 pulley ?

Cool, thanks. Oh, that was an 8" lower pulley, right? That's really spinning that ol' S-Trim.

Later,

10-4 Ray, I'm still running a T-trim. Right now I think I'm running a 2.83(I think). I have a pulley that is the next size up from a 2.5 but I haven't put it on because I only have 30# inj. and I don't think they handle much more boost. So I'm just going to use the NOS(for right now) to make more power if I need it to get to my goal. I'm looking for some 11.8s w/the 50 shot and 11.5s w/the 75.

I'll find out Sunday how much she can hold!!
