There is about 10k more rpms just with the different step up ratio of the F1
around 58K with a P1 your talking 48k
With the F1 flowing alot more air to begin with I'm sure your near 12-14 psi as a guess
With the F1 having a 5.0.1 and the P1/D1 being 4.10.1
Put a boost gauge on it nice too see the Graphs aswell to See how much that belt is slipping on it

 

This is in fresno!!!! it's rooming the streets...awesome numbers, where are you guys located in fresno, and do you guys have any goodies for the obs?

 

We are going to use the same charger on a 383 hear in about a month. As soon as i get it wraped up, i will be able to check what kind of boost it produces. The guy lives out of town, so it makes it hard to just throw a boost gauge on it. We will find out either way. Reguardless it is a lot of fun to drive.

I have a 383 you can throw that blower on

 

We can get priitty much any parts for any vechical. But we focus on LS1's. Fowler and Clinton are our cross streets. We are in a 5000 sq. ft. shop just a street off set from fowler.

 

Before the "no boost gauge" post, I was thinking 'no way'. 8psi is on a built 6L motor should be under 600 rwhp.

Tose are strong numbers 700 rwhp is stout in any vehicle, much less a truck. Highest dyno from a new body GM truck I've seen.

 

I was impressed that i couldnt even get on it the first time without dumping a tone of fuel on top of the factory tables. After i added the fuel I found out that the fuel pressure drops even faster when there is not enough pump and line size. We upgraded to the Bosch 420L/hr Inline pump. Using a half inch feed line into the pump and factory line to the rails. Still droped to 40 PSI before we even got to 4500 RPM. So then we just ran half inch the hole way and 3/8" to each rail. It didnt complain any more after that.

 

Sean, keep us updated on the new truck products that you guys have lined up. Sounds like 2005 is going to be a very interesting year for the trucks!

 

Congrats Sean!

Hey what is the second tank for? Seperate fuel for DP Nitrous? What octane are you running for that? Are you just using ARP bolts on the heads? Have you tried any of the "new" Cometic gaskets yet?

You will have local competition soon Sean very very soon!

 

Your probably looking at a different truck. That one has 116 in a cell for his nitrous. On that truck we put a nossle's 175 shot on it with cam and long tubes. As well as a 4L80E tranny. On a stock 5.3.
