i thought 450s would run decently till 15psi?

 

450's are good for 300hp.

 

15psi on what turbo?

psi doesn't mean ----, it is all about how much your turbo flows, and your hp output.

 

so you got the water lines worked out?

 

yeah i never had them crossed..it was the spark plugs.......
im boostin 12psi on my b16 my friend says i should be toppin about 330hp
maybe.....

my injectors are prolly too small 2morrow im gettin some 850's
---- these dsm *****

 

Well, just the flow really. How much air you have going into your engine would determine how much fuel you need, horsepower wouldn't really have much to do with it.

Good call. 95% duty cycle is maxed, besides that I bet the injectors themselves aren't up to par.

 

What duty cyle you think 850's would be at for 12psi?

I wanna run 18 maybe even 20 if my rods can handle that

can u get injectors too big?

 

Get a real fpr and crank up the fuel pressure injectors go along way with high pressure. I have tuned alot of 200+ whp all motor cars on stock 240's lots of fuel pressure and 100 percent duty cycle

 

Cause that's totally FAWKIN AWESUM for the injectors. God forbid it gets stuck open and wipes the cylinder, dilutes the oil, and kills all the bearings. Or sticks closed.


You can calculate how much fuel you'll need by figuring out your CFM at what ever pressure level you want. Take that airmass and figure out how much fuel you'll need from your desired A/F ratio. Then you can figure out if your injectors will flow enough.

Easy way to figure out your initial cfm per horsepower is looking at the specs for a stock motor and just incrementally increasing the horsepower, working out what CFM it is and going from there.

 

how about running 10's on a turbo b16a with a 50 shot on stock 240's and an fmu


Car went to the finals at the first import nhra in pomona
