Performance question on this injector

["Turbo-T"]

Gn/T-type.org says the #36 lb blue top injectors, p/n F4SE-B1A / 0280150967, are good for an estimated 430 hp and 11.70's in the 1/4 mile.

My question is, is this number on gasoline only?

Or if alky injection is added, can this injector be good for more than 430 hp?

Thanks...and here's the link:

Blue Top Injectors

36lb/hr x 6injectors = 216 lb/hr

216lb/hr /.6 lb/hp= 360hp

if you run lower boost you could get away with a leaner AFratio wth only .5lb/hp = 420hp

these are gas onlyat 100% duty with no alky but on todays 93 with 10%ethanol added figure 5% less hp

and figures are at 45# base fuel pressure , up the pressure and you could get more hp

most recommend sizing injectors to run at 80%duty
with alky/93 and a te 44 im running ~36#hr through my 55s to go 120 at 11.3s witha 3600lb car (65% duty)

what is your et goal and car weight
i would think 8009s (42#s) or 50#msds would be better for your combo

Car weighs 3650 w/o driver. My goal is to hit 11.50's in the 1/4 for now. Not sure though if my turbo and IC will support that but I did read elsewhere that I should be good for 11.70's

come up short on the fuel delivery at the top end of the track and run lean and the outcome will be costly , more so than a set of injectors, this is when having logging equimpment and wideband pays off.... start slower record the runs and reveiw where the fueling is , if its ok try for alittle more , if it shows its starting to lean step back and reconsider your goal or uprade your equipment

btw with your vehicle weight 11.7 will take 450hp and trap about 116 , it is possible with alky "if" the 36#s flow at rated volume you should be able to do it if you can get the injectors to 100% in the chip
also keep in mind the trans has to hold up for this , traction has to be good and youll need to be 60'ing in the low 1.6s , with worse 60' youll need more hp to reach your goal

Thanks for the info. A wideband is next on the hit list if not a powerlogger.

A little recap...

36lb/hr x 6injectors = 216 lb/hr

216lb/hr /.6 lb/hp= 360hp

Yeah this is what I'm thinking too....after I installed the powerlogger, I found I was getting as high as a 105% injector duty cycle, on these injectors, at 24-25 psi and that's with the Alkycontrol alky going.
