just as the title says. im sick of fooling with the begi 2025 unit. just wanna go with a vortech, but it seems i got my hands on one for a 240 ? heres a couple photos of it....

aside from the colours, that's what the greddy Vortech alright!

May be you want to re-confirm the disc inside!!

 

is there inscribing on the discs? i think im gunan take it apart tonight and check it out.

Scott

 

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?

 

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

 

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?

Scott

 

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.

 

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.

 

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.
