well just wondering what y'all think I might be able to get out of my set up . Its a 99 5.3 with a p1sc ( with a 3.7 pulley) , a 221/230 581/591 114 lsa, ported and polished 862, long tube headers, circle d 3200 stall . I am also redoing the intercooler and piping since I don't like how the stock one is . also moved the air filter to right behind the driver side head light .
Any thoughts are welcomed.


Hope to have some dyno results in a weeks followed by some time slips. So just curios why y'all are thinking she might make.

 

im gonna say high 3xx low 4xx range depending on how much boost you make

 

Im really hoping for more since I should almost close to that with just the procharger. I was pushing around 14 lbs before hand and the truck had gone 13.3 @ 104 mph with a 2.1 60ft. Truck is all back together just wating on my pcm to come back from my tuner in Florida.

 

With that cam Id imagine you are spinning around 6900 rpms. Ill say mid-high 400s

 

I'd be happy with that for now. I also know I picked up 40cfm on my heads from .300 -.600 lift. I will be adding a little shot to get since I want over 500rwhp.

 

I think you'll be deep into the 400's with this combo. The higher you spin it the more boost you will make... so be careful.

 

I won't be going crazy with revving it tell I get back to Florida in two weeks and Jeremy finishes the tune. It's on a mail order right now from him.

 

should be going on the dyno Monday or Tuesday. Just finished it all up today and toke the time to do a boost leak test and it held at 20 psi with no problem. Yes it is more then what I'm boosting but wanted to make sure it was fine. Will up date when dyno run is done.

 

Bringing this back to life. Any updates?

 

Broke the trans so doing a 80 swap and have had other projects.
Will be finished with in a month and updated.
