Big Injectors... need advice

csschupp · 06-13-2008, 09:24 AM

I'm in the process of planning my turbo upgrade and will need to get bigger injectors since I run E85. I'm currently running 830cc modified stockers (which will be for sale soon). The car will need 1000 to 1200cc (not sure yet) to run E85. Luckily I can do top feeds since it is an 07.

I've looked at RC Engineering, Ultimate Racing, and Deatschwerks. Here are the prices:

Ultimate Racing:
1000cc Flow-Matched Fuel Injector Kit $525

Deatschwerks:
1100cc $599

RC Engineering:
1000cc $400

Anyone have experience with these brands or can you suggest others? I'm not looking to cut corners.

Thanks!

DW all the way. Man, those injectors are perfect. They really do a good job on them. Plus, you get a refund when you send your old ones in.

I have tuned several and DW by far has hit fuel targets dead on every time. All of the others are a bit off at times. Their customer service is top notch as well. Mike and David are great guys.

I even told one guy to get rid of his decapped stockers and get DW because the fueling was bouncing around. With the DW injectors, the WBO2 reported fuel targets dead on after scaling them. No wobbling, just a dead on fuel curve that lined up perfectly with the OL fueling map (after getting the scaler right which is almost always near the advertised CC/MIN).

I have gotten so good at tuning DW injectors, that I can just guess at latency and scaling and it is almost dead on (as long as the MAF sensor is ok).

I wish I had the pumps around to go straight E85, instead I am using Meth which is an additive to the gasoline and will not get the same power you will get once you have the fueling headroom (if I still had the stock turbo.

). I would have to upgrade my DW 750's though to run straight E85. But it would work so much better than Meth injection and more reliable.

This seems to be the general consensus. I guess you really get what you pay for with injectors then?

Yeah you do. Don't forget you get a core refund too, so the increased cost is offset.
