Ok so im buying injectors and all my other parts for the sc. but i found a good deal on rebuilt flow matched bosch 52# injectors, i think the flow was upped to 52# so im not sure what they were originally. But im hoping someone can tell me if these will work in my car without too much hassle on the tuning side. Ill only be running about 10 psi inter cooled. Im shooting for about 400-425rwhp. I know the 42#s would work, but i figured these will give less duty cycle and over all pressure, and allow me to upgrade later, and i see so many people selling there dyno 42# cuz they ran outta power. So someone fill me in, or let me know if there is anything to worry about.

 

What is the part number embossed on the injector?

 

wish i could tell you cliff, i already bought them, so im hoping they work they are ev1 style bosch injectors. Do you have maybe a down and dirty explination of what i may have done to screw myself? lol are there like multiple versions that dont work well in our cars?

 

I assume you do not have them yet, when you do post (or PM) the Bosch part # and we'll see what you bought...

 

As long as you have a tuner that is comfortable with bigger injectors for that power level you should be fine. I'm running 60#s with my current power level in my sig but like Cliffy said we won't be able to help much without the Bosch part #s

 

ok cliff. i dont have a part number...dont ask, im in the middle of figureing this out. They appear to be factory red tops, so 30#s rebuilt to flow 52# and flow matched, was what he said. So i obviously have a few simple questions. first being, can that be done on 30# injectors...2 if it can is it reliable? and 3 how can i check them asap from my house. Because if i have an issue i need to find out fast, before i put them in the car. Thanks. oh by the way i see a ford symbol on them and they are red, thats my deduction on what they were originally lol.

 

based on the little info i have and the very few numbers i pulled off them this appears to be the part number. 0280150945 / F1SE-E5A

edit: also they were supposed to output 52#hr at 40psi

 

Those are 29.4 lb/h injectors--they may have been "rebuilt to be 52 lb/h", however readily admitting that I have not yet heard of everything, I have not heard of this being something commonly done.

The only way the verify it for sure would be to send then to someplace like RC Engineering and have them tested--or install them, set the low and high injector slopes for appropriate values (say 62.4 and 52) and see what the fuel trims and AFR at WOT look like...

 

Steigmeyer ports and flow matches injectors. It's quite commonplace over in the svt world. People send out their stock 39# injectors to Steigmeyer and he ports then and flow matches them to 60lb injectors so guys don't have to go blow $400 or whatever they cost these days on injectors. Do some searching on SVTP about this subject. Guys are using them to great success from what I heard. Steigmeyer can even take our stock injectors and port them to like 42lb injectors.

Also, if the tuner knows how to tune then there should be no issues tuning any car with any size injectors. Honestly, guys that need 80lb+ injectors do not need that much fuel all the time, period. So if you can tune a street driven 1000rwhp car with 100lb injectors, you should be able to tune a 400rwhp car with 100lb injectors. It's not optimum because then the injector is only open so long and you don't get good enough atomization. But I know plenty of people using big injectors on street cars making big power and driveability is just fine when not in it. So you should be fine.
