RC 750cc & 720cc injectors. (750 only available?) / (VPC 720cc question)

[MK3Brent]

Part 1:
I was reading up on injectors, specifically RC "720cc" injectors that Genna ran in the red car... but all I see on HFP for RC's are 750cc.

I need a set of injectors to support 700hp MAX, with usual workload to do 600 daily.

Part 2:

I'm running a VPC with a 550 chip, but I know several of you are using the same.
My question is: How is drivability on 720+cc injectors with the VPC / AFC combo?

Thanks.

PS. I'm dynoing this saturday, so I'll post results... good or bad.

It will work.....I used Vpc emanage combo, but blackdevilsupra used Vpc afc and 720 injectors or was it 750 injectors.lol

(06:40:50) Howard (Blackdevil): I used 780cc's (Delphi Injectors).

Thanks for chiming in, Ant.

I think I'll get some 680's from a fella on SF and try them first.

RC makes 750 but the 720 would be either GReddy or Denso (same thing)

I did a VPC/SAFC2 with 72lb/hr inj for a long time in my supra and never had a problem with day to day driving. The mileage wasn't the most impressive around town though....

Well I don't drive the car more than once a week, if that... and wanted to have some head room to hit 600hp w/o running out of injector.

Looks like 680's will be going in... should make tuning a little easier compared to 720-750's at the moment.

I think I'll run a dual feed to the rail first though.

Thats what I did.....Took a spare fuel rail to the machine shop and had him make a hole dead center and tap it the same size as the front feeder. I used the feul damper as a feed the center as the return and get fuel feeding from both ends equally. CSI still in place also.
