60 overs pulse

[WisconsinHick1]

My understanding is start by taking your pw from your big tune with your stock injectors and then from about 1800 - 4000 rpm range you subtract 20% that is a good starting point.

2800pw x 20% = 560pw

2800pw - 560pw = 2240pw

A 2000 us would be fairly equal in fuel to a 3100us. I would then go up to what can support 22000 psi at wot.

Im not sure i would put that much fuel to a stock turbo?? on my 60% overs and dual pumps i ran 11.71 @119 with the s475 batmo and egts got to 1700* about 6 runs later i had a nice hole in the stock piston. 2496pw 29.5* timing

I would go until you just start to get some smoke coming out at WOT so you don't over spin that turbo.

Are you talking about 2000us being too much? That would fairly equal to a hot tune with stock sticks. That would be a starting point. To hold rail on a single stock pump you may even have to go down. Each truck is different.

I'll try 10% and go from there. Thanks man I appreciate it

Think I'm going to try 28 degrees timing with 2425 (what I've been running) with a 115-120 fuel shot.. sound like power, or one big disaster to you guys? Too much timing?

No sorry i should have quoted him, 2400pw is ALOT of fuel with 60% overs and a stock turbo. Shit will be hot and i dont see a stock cp3 holding rail.

Yes you got that right.

This is a 24-2500 pulse width with stock turbo and 100 overs. LOL
