Had it on the dyno, made more power, but still not done, couldn't finish the entire session.

Truck is out of fuel!!! The truck wouldn't handle 8.5/9psi and injector duty cycle was at 122%, but I think the fuel pump is failing. The truck is hard to start sometimes.

But, power did go up. 525hp at 8.5psi, it was a tad colder today, so that helped.

I tried 12psi real quick and the a/f ratio was definitely lean up top.

I've been driving it on the street with 12psi, but I don't stay in it, the dyno loads it much more than the street can.

anyway, back to the fuel system.
I'll change out the pump, if not, I'll look into twin walbros, but I know 1 a1000 will do it.
I might just leave it at 8psi and be happy, but I know it has a lot more left with some fuel added.

 

Are your rocking a 6L?

 

Ya, recap: 6.0L / 80e / 3000stall (going back to stock), 3.73's / fat 20's

The truck feels just right, 8psi might not be that bad.

haha jk, I'll get it up to a safe 12psi soon!

 

Not bad Allen...

 

Why u going back to stock converter

 

Well damn it those are some good numbers!!

 

who needs more gas when you can add more meth. lol

 

Thanks, we'll keep going forward with it.
Most of my parts are here to start building kits.

This yank converter i have is awesome, and worked well with the sts, but I don't need to brake stall at 3500rpms anymore. The boost comes in quick and i think a stock one will be just right. If I can get this yank resized, again, then i'll keep it, I'd much rather had a strong converter than the stock one.

Thanks, I can't wait to get the new cam in. Maybe with fuel and cam, 12psi will hit 600.

Even though meth is proven and will add to the fuel system, I don't like it for some reason. I hate filling my tank with meth all the time and relying on the meth kit for added fuel.

 

Another cam? I thought u had already installed the new cam? Or your putting another one?

What size injectors are you running?

I'm guessing 60lbers and a single walbro won't be enough for a 6.0 and about 15psi?

 

I still have small cam 212, I got a new one spec'd out that I haven't put in yet.

They are 60's, so it has to be the pump.

It probably won't be enough, so dual walbros or an a1000 will be enough.
