Injector dynamics 850. Because you won't need to get bigger ones again and you can't over injector. Easiest to tune as well.

Litle, I thought getting injectors ported theoretically could cause different amounts of fuel to be injected per cylinder? I thought that was why ID was one of the best to prevent that?

I've never had a problem bud, my tuner has never had a problem tuning me, my AFR is always right where it's supposed to be. It's easy to tune too. They even took my Ls1 28lb injectors up to 65lbs for my 4th gen no problem. Drive ability is ok for it being a stroker and big cam.

You need to read up on injectors.

FIC does great work and has great injectors. As a matter of fact, all the injectors LPE uses in the 650 cts/zl1 kits are resized factory injectors. AND they supply the injector tables for hpt or efilive. The offer several sizes. For the night fury and a tvs a FIC 60 would fuel it but it would likely be around 85%-90%. Could probably stand a 72lb. And have a little room to grow.

I have FIC 850s for my turbo application, I have not had any problems with them. There was some debate a while back because of a few people having issues with them. I think that it was just a random case of some bad parts, which will happen to every manufacturer at some point or another. I believe that customer service took care of all the problematic injectors which is the important part.

I would go with FIC 850s if you want to keep the price of your build down, but if budget is not a factor Injector Dynamic 850s are your best choice.

If you decide on FIC's, realize they size them at 3 bar pressure (42 psi) so the 60's are 72's at 4 bar (58 psi).

This is true, if you call them or when you order you can specify whether you want them sized for 3 bar or 4 bar.

I run ID850's and they are great, easy to tune. If I was doing it again today I would go ID1000's, not because I need them but because they seem to have changed their pricing and 1000's can be bought for the same price if not cheaper.

I have the 63 lb injectors that came stock with my Whipple. I plan to put them for sale soon. Very low miles on them. Let me know if you're interested.

This is true.. They retail out only a few percent over the ID-850s.. However, remember with the ID-1000's they only come in 48mm or 60mm lengths, so you can purchase them in 48mm length and use the FSP Billet Fuel Rail Spacer kit

ID-850's will give you room to grow. WIth the TVS I recommend the ID-850's for great fitment, quality all-around injector.

Matt, didn't realize the size difference. Why is it that 850's give more room to grow? Always learning!1

Did you get that TB yet?
