I am getting ready to put the truck in the shop. i am adding PRC stage 2.5 5.3 heads, gt2-3 cam, j-tube and 90mm tb, 60 lb injectors and lingenfelter 100 mm maf also an extra magnuson heat exchanger. The dyno #'s in my sig do not include the long tubes or the 3" exhaust, i was running shorties and a 3" catback so count those in the mix. do you think 500 rwhp and maybe 550 rwtq is reasonable to expect??

 

Everything in my sig and I got ~410rwhp and ~490rwtq at ~11psi on 22's ... have read if I had dyno on 17's I would have gained 30rwhp and 30rwtq. Should be there easy but might need meth to cool the boost since my iat were climbing with a 3.0 pulley.

 

I think you should get that easily on a dynojet. Who are you getting to do the work? Are you coming to the ls1truck track day at SAR later this month?

 

I really have no idea but I think you should be close. Good luck, hope you get there!

 

I use a shop here called auto-tek for all the stuff out of my league. Yes, I am gonna go to track day at SAR but probably as a spectator. I am not gonna get the work done for about another month. I could make a few passes on street tires but not sure I really want to.
