Simple question which is a better injector the motorsport 34lb injectors from a 4.6l from (gefracing.com) or the racetronics 32lb injectors? just got the heads p&p so dont know which way to go. called the guys at gefracing and they were no help really, they couldnt tell me weither the 4.6l 34lb injectors would fit my lt1. And racetronics doesn't have a phone number. so check my sig( I know it's long I will shorten it up this week) and let me know which way to go.

 

Ford (Bosch) doesn't make 34# injectors as far as I know. They are either 30 or 36. For your mods, I'd recommend 30# injectors. They flow 31.6# at LT1 pressure just like Racetronix. Personally, I would recommend Ford injectors just because I've had really good and continuous look with them both in my car and in the cars I tuned, but since Racetronix is a sponsor here, you might give them a try as well.

 

The Delphi disc injector has some better characteristics which are listed in our ad. SVO Bosch injectors are a 30+ year old pintle design.

In the case of an LT1 the spray pattern of the 621020 is closer to the factory Delphi (RP) injector than the SVO injector. The Delphi disc injectors will fit an LT1 fuel rail / intake.

At our current sale price you can't go wrong.

well I saw the 34lb fms injectors from gefracing they are for a 4.6 liter. but as for them being svo i dont think so. I really dont know if there is a difference between svo and fms. As for the racetronics they seam like a quality product but would i be able to throw a 100 shot with them only being 32lb's?

 

You did not state whether or not this is a dry or wet shot.
It would be best to stick with a wet system.

Either way we have injectors in 37#, 42# etc. all the way up to 95# to suit your needs.

 

i think svo and fms are the same..i could be wrong though.....i'd say they'd be enough cause ur engine is still the stock displacement right? i'm sure someone on here will have the right answer

 

most likely it will be a wet shot because i am kind of weary the dry systems since i dont know too much about it. but thats in the future. racetronics how much flywheel horsepower can your 32lb injectors handle? Also those 4.6 liter 34lb fms injectors from gefracing will they fit on the lt1?

 

I belive the mustangs use a lower fuel pressure so those would really be like 36#s?????? not sure thou. Not sure on the fitament either.

 

Ford rates their injectors at 39.2 PSI. 30s will flow 31.6 on our pressure of 43.5. FMS=SVO

There is no need for a larger injector with a wet kit.

 

so is there any difference between the 4.6 and 5.0 injectors or are they both the same and will fit the lt1

 

ditto, how much HP can the Racetronix 32# handle and is that motor or should you go bigger if you plan on spraying a 150 shot

 

That depends on the fuel pressure, motor's BSFC, max. engine RPM, battery voltage etc.

There is no problem going up to 42lb/hr as they can be tuned to support factory HP all the way up and beyond 500FWHP. Determine your long term goals and spend your money once wisely.

 

battery voltage?

 

Yes!

 

I recommend you go with Racetronix.
