I don't think so, at least I don't see one in the diagrams. Eric would be the guy that would know as he just changed his out.

Cobra SVT #39 injectors are still for sale, shoot me a PM anyone interested. I'll give it a day and then post them up in the for sale section.

Cobra injectors are sold, can't wait to get the new ones.

This part has me pretty excited.
Static Flow Rate @ 58.0PSI (400kPa): 53.7 lb/hr = 6.77g/s = 552cc/min (+/-3%)

Thats awesome. Its a little crazy, but the injectors that are going in this winter are 157lb/min.....lol.

By the way, I was thinking about this today. One thing you could do to seriously configure your fuel system is to add a surge tank and keep you factory pump in your factory tank. This way, you can add a much bigger pump from the surge tank to the rails to supply your fuel. And....the best part is, you will never cavitate either fuel pump. So, when you decide to stop f'n around and run full slicks, you can still run 1/4 tank of fuel, launch, and still get full fuel to the rails with out worrying about the fuel pick up in the factory tank.

Cool dude. You think that was lean....... LMFAO when I finally tried to tune with the new cog setup on my SVT39# injectors i went to a 17+ AFR!!!!!!!!!

I have obviously taken them out along with the Walboro 255 pump and have the SRT 4 injectors waiting to go in along with the Aeromotive Eliminator pump and an entire fuel system.
