fuel pump voltage boosters shorten the life of the pumps. i would not recomend it.

 

I'm not going to use them anyway if this motor can outflow 2 fuel pumps it is doing pretty damn well, that or my fuel maps need a look at

 

i was quoting the msd fuel pump that they "say" can be used for it. its the same pump i have and i was not refering to using a voltage booster on stock pumps. thats just asking for trouble. just clearing that up. what size injectors are you using?

 

I have a heap of 295cc injectors laying around an upping the pressure I can get around 340 out of them but I dunno will probably need something slightly bigger. The stockers are 200cc a piece and there are 6 obviously 295 is a stretch I would think anything 350+ would be better once I have the stand alone on it I can watch the duty cycles and decide from there I'm pretty cheap.....while I wrote this messge I got reaaaaaaaally drunk so I'll sort out if what I said is not just bullsh** later

 

i'm sure you were drunk. 295cc are only good for 260hp don't go any more

 

Notes to self "do not post when wasted"

Haha yeeeeeah kinda was not in the right state of mind there so here we go with a post that is based on a good state of mind and some quick math. I can pay used price and get drop in (I think will check later) 440cc injectors or go the cheap route and pull some subaru injectors which cost near nothing which are 425cc but that will require some custom railing and such since the injectors are "weird" They will be pretty high in their duty cycles at that I can up the pressure to help but that is limited in how much it can help.

Finally I have a contact that can get me 800cc injectors pretty cheap new that is getting pretty big on a 6 cyl. Still it will most definitely be enough even if it idles a little rough, thing is cheap is a relative term here it is not cheap just discounted heavily so I'll see what I can dig up I normally know some people that know some people that screwed some people

 

800cc are more than you need but as long they are cheap go for it

 

Yeah I think I need about 470cc at least for reasonable duty cycles so 800 would be fine.

 

Don't forget about pressure!! You could probaly get a good solid 320 with 6 295s with pressures around 65~70. But I'd get some diff ones anyway. 6 750s in my bmw that sould do at least a good 200 to the wheels...
