I currently have rc 750's maxing me out at 399hp. Just picked a t67 and I need bigger injectors. I seen 1000 precisions for a good price, but wasn't sure if they were as good since rc's were like 70-80 bucks more. Is anyone running on precisions and are satisfied with there performance? Or should I get rc's? Thanks in advance!

 

how are those injectors maxing out at 399? whats your fuel system? my 550's were not even close to maxxed out at 380.

 

420whp on rc750's with still more to go.

if you are using all the fuel of a 750cc injector and are making less than 400whp something else might be wrong.

you should be able to get close to 500whp with some good fuel pressure.

 

Well I didn't mean maxing out. I should have worded it better. I am running Neptune, with aem fpr, walbro intank, aem fuel rail with a b&m fp guage. I know I will need larger injectors is what I should have said. I think on the rc site, the 750 are only good upto like 425 or so. I wnat to push around 500 with the t67

 

you should check out the bosch 1000cc saturated fuel injectors. there is a post on the first page about them. they seem to have some really good spray pattern and can easily idle/run the engine with some good air/fuel ratio without sputtering.

i think i will be getting those in the spring time.....to bad 1000cc is way overkill for what i want but will work great for your application.

I'll take a look at those. Do you knw how much they run? I seen precisions for like 279 and rc for 359, hence the reason for my thread.

 

ahh that is the trade off.....i do believe those Bosch injectors are about 400+ per set of 4. (no resistor box required)

i personally like RC injectors. but many others use precision with great success. but either RC or precision in 1000cc will require a resistor box.

 

Yeah, that's what I don't want to do, but would have to. I checked out that thraed and those Bosch' sounfd really good. I may just save up for those. Nothing beats reliabilty. I damn sure don't need my car idleing rich just to sound good at idle. lol The Bosch' could be hooked up the way i have my 750 rc's now? Thanks for the insight.

 

So you guys saying that if I order some 1000cc injectors I will need a risistor box in order to install them on my car, I have a LS/Vtec that have been buying parts to complete my turbo set up and the injectors is one of the items that I was waiting to get more info on them.
I will be using a bullseye T04B 60-1 so I was wondering if the 750cc will ok for my set up or should I go for the 1000cc just to be on the safe side.

 

if you get RC or preciscion 1000cc injectors yes you will need a resistor box.

RC makes 750cc injectors that does not require a resistor box. the 750cc should be easily safe up to around 450whp. 500whp would be at is extreme limits.

the new bosch 1000cc injectors do not require a resistor box and they perform well at low duty cycle making them very nice and easy to tune and 1000cc's should support over 650+hp easily if not more.

1000 bosch's it is. Just gotta save up though. Those things are a hefty piece of change.
