Exclamation I've been VERY busy, now I need predictions.

Finally getting this car running, while going to school full time, and working full time 7days a week mandatory, a year later.... the snake has awaken. Still plenty to do of course, but i'm looking for predictions. What will my max hp/tq numbers be at fast lane motorsport's dyno. My mods are in my sig. I can wait to see what you guys think. Thanks again for all the help, couldn't have done it without you guys.

3.4 pulley on the p1sc+ the drop in compression with the b heads, id say your gonna see 380-410rwhp. As far as torque its gonna be around 370-380. You definatly should of went with a way smaller pulley especiually considering u have the shortblock and the fuel system. That fuel system is WAY overkill for a P series procharger.

The guys at procharger said thats as small as i could get without the belt slipping? What do you think about that? i'll go buy the smallest pulley that will work with the stock serpentine setup. And I will be upgrading the procharger head unit in the near future, next year or so. Just need to save up a little.

yeah, hoping to make it down there in the next few months. I've never been, but i've been told they do alot of stangs, and I should go there. You have a HP/TQ guess? I'm hoping uber's is low hahaha, but we'll see.

I'm going to have to call them again as well... let me know how the 2.55 works, and i'm certainly going to go that route. I stressed that i wanted the smallest possible pulley that I could. I thought 4in was stock. 3.4 is smaller than what came on it originally

If it was a 4 inch pulley i would imagine thas a 6psi setup

IMHO i dont see belt slip being any issue for your setup, I think you could easily go down 2 more pulleys and not see too much belt slip. Get a good belt and you should be fine running 10-12 lbs with no belt slip.

I am running a 3.33" pulley and am making 11lbs, but i am a vortech tho.

And did you ever post a video of your car running now that it is running right? I want to hear it
