stock sr 370cc max?

[iamwesley]

What do the stock 370cc injectors max out at HP wise?

[orion::S14]

~250rwhp (safely).

- - - - -

370/10.5 = 35.2lbs/min (assume 100% duty cycle, .55 BSFC)

(35.2*4*1)/.55 = ~256rwhp as a MAX.

would 7lbs on a t3/to4e 50 trim be okay on 370cc?

/\ im runing 10 pounds on a t3t4 61 trim stock injectors, walbro, and safc set to richest. hasnt blown up yet.

[qvester]

i dynoed at 240rwhp with stock turbo stock mafs at 13.5 psi hit 89% on injector pulse reading so ya

I asked my friend the same question and he said their good up to 300HP at the crank.

can you please explain where those numbers come from. thanks.


and s14 blacktop, your friends an idiot then. :rl:

A good estimate of injector flow:

injector flow in cc / 1.5 = approximate horsepower

370cc / 1.5 = 246 horsepower.

To convert lbs/min --> cc use a factor of 10.5. 370cc / 10.5 = 35lb injectors
50lb injectors * 10.5 = 525cc
72lb = 756cc

approximates

can you please explain where those numbers come from...

Google - search for "injector flow horsepower fuel pressure" and you'll get a bunch of sites...

www.holley.com (http://www.holley.com/HiOctn/TechServ/TechInfo/TchArtcl/Artcl07.html) has a good page...but there are tons of others with similar info.

TurboSaturns.net has some great info on this stuff as well, check it out.

By the way, a good "BSFC" to use for a turbo KA or SR is (.55)...
