I am buying a P-1sc for my 95 lt1 with a good dyno tune what kind of numbers can I expect from a stock motor, also what bolt ons will do well with boost
Thanks Matt

 

I would say you can expect anywhere from 375 rwhp to 400 rwhp.

Thanks what can i do to improve that # as far as bolt ons go?

 

Headers, aftermarket cam and ported heads will all help.

 

that is assuming you have headers and a full exhaust. ~400rwhp. Who cares, you'll blow it shortly thereafter anyways

 

I love my P1-sc. Between that and the long tubes, I make 30hp/psi. A lot of that has to do with the tuning as well. I ran 414rwhp on an honest dyno.

This was at Protech in Toronto. Their dyno is compared to an engine dyno and timeslips on a daily basis. A friend of mine just dyno'd there and he dyno'd 60hp less than a shop in town. Even their AFR was off. lol.

Anyways, long story short, expect 380's without a good tune, over 400 with. And do yourself a favor and just get the longtubes now.

Later

 

Thanks steve I think long tubes are next for me, how will a 58 mm TB do?

 

Don't bother with the 58mm. It's just a valve. And with boost, you don't need it.

Thats good to know heres another one for you, I use a crane hi-6 should i bother with a boost retard if so what would i gain
Thanks Matt

 

You definately want to get a boost retard. It makes tuning the car much easier and it's safer, IMO. A little bad gas or some knock, just turn a **** to increase or reduce the retard. With the blower and a stock motor, it's more a question of how long it will last than how much power it will make. As far as your original question, are you getting the intercooled kit or the non-intercooled kit?

 

Chris I thought all p1sc kits were intercooled if not my kit is intercooled.
2 core
any info is greatly apreiciated.
Thanks Matt

 

Agreed


I am making over 700 rwhp with a 52mm TB.

 

#'s in sig. No internal mods.

 

Dj thats were i would like to be with mine im basically setup like you, I see a lot of guy running the lt4 KM with blowers Why?
Thanks Matt

 

I believe ATI offers a version of their kit minus the intercooler that is supposed to run 5-6 PSI for people who want to save a little $$$$$.
