shinobix

No, you might want to measure the size of the disc and the ring.

The factory greddy came with a 12:1

if you have something like what you seen here, just the disc without the ring. $10 bucks it saids you have a 12:1 disc. If you have disc and ring, that would be a smaller caliberation disc, I am using 7:1 on 1.8 injectors.

2.72" Dia for the 12:1
2.47" Dia for the 10:1
2.22 Dia for the 8:1
1.85" Dia for the 6:1
1.59" Dia for the 4:1

yup, just pulled the thing apart. looks like i have the 12:1 disc. so what kinda disc you think ill be needing if im shooting for 200+ hp. walbro 190. 305cc injectors? will the 12:1 disc be enough?

Braineack

iTrader: (62)

noooo, more than enough. you want a 3:1 or 4:1


100psi on 305s = 275BHP


12:1 x 10psi + 50psi = 170psi

3 x 10 + 50 = 80psi

4 x 10 + 50 = 90psi

shinobix

hmm, wait lemme clarify. i have a 195lph. not the hp version... when my friend ordered it for me he ordered the wrong one. so i have a max fuel pressure of 90hp.

with the 12:1 disc how much boost can i run to run it to the max settings?

standard wastegate pressure should be fine if your pump doesn't dead head. But it's gonna be real rich.

Get a 4:1 disk.

Braineack

ah, well you can run plenty at only 90psi, i'd still get a 3:1 or 4:1 so it doesn't just completely dump in the fuel right away.

you'll be able to squeeze a good 250-270BHP, whatever psi that works out to.

shinobix

roger. im running about 12psi rightnow on the begi and sometimes i can get it to start because the fuel pressure jumps to like 60psi when im cranking it over.

hopefully the vortech will help me out.
