Ok I got a a 97 with 4k GSK , 024 delivery valves, air dog 150, port and polish on exhaust side, steed speed manifold, with 62 mm over 75mm compound setup with fire ring and headstuds and I was wondering what you think would be the best injector for this setup? I'm running a 7X.014 but I see a lot of people are running 5.???. I got 5 inch exhaust pusher intake, with water - method injection . What are your guys input? Thanks for the input!!!

 

Leave it. Unless for some reasons you think it's under performing. Most just don't buy into the extra hole hype as I don't think there's enough proof of an improvement and the extra potential risk of the tip cracking. But Id leave them. 7x 14 is fairly large so you should be good.

 

I don't think bad about them but everybody I talk to think they are WAY to big. I mean even at 60 lbs of boost they put out a little smoke but they seem to think I would be better off putting my 5X0.12 back in it. Just wanted to throw it out there to see what other people thought.
Thanks again for your input!

 

They are fairly large. Probably close to a 5x18 equivalent but I mean if they are super dirty I wouldn't bother. 5x12 is a tad small for a compound set up. 5x14 or 5x16 would be more ideal. I persoanally wouldn't waste the time and money/ effort. If afc live isn't something you have you may want to consider it to help tune it better. I'm not a expert on compound set ups but 60 psi seems a tad low to me for a compound set up. I could be wrong tho.

 

7x.014 are closer to 5x.016 or 5x.018. Doing AFC live or Attitude adjuster would be nice for tuning.

 

I really don't know what it can produce yet my boost gauge only goes to 60 haven't installed my new 110 gauge yet.
