Anyone successfully pulling this off?

 

I have RC 1000's no trouble with them. I scaled them 700 stock 750 mod. But I use ECUflash to.

 

I run AMS/Precision 1000cc's and ran them fine on the UTEC. Scaled to 800. no ECUFlash or anything.

 

used to run 1000's with 35r and utec with no problems, but then i just sold it and went back to the stock ecu

 

Worked out great.
Scaled them to 770/700 and it idles and runs great. I still love my utec. Just dialed in a fresh map during my lunch hour for my new 50 trim on meth. Spun all 4 in 2nd. It's a beast.

 

Currently I am running a GT35R 1000CC rc injectors and a UTEC @ 24 pounds with 495 at the wheels with no issues. I am getting ready to pull them and go to 1200cc injectors and an E85 tune at 32 pounds.

 

What have you done to the fuel system. I am worried about runnning out of fuel with a 100 shot on race fuel.

 

I have a single Walbro 255 lph pump, and Perrin fuel rail. I am however now with these 1200cc injectors right on the edge of needing a second fuel pump. Over the weekend we safetly got to 27 pounds at 559 wheel horse with no fuel problems. I plan on running it all the way up to 32 pounds and hopefully 600 wheels horse on one pump, and it shouldn't be an issue. I would think the only place you may have an issue is when you dump the juice it may run lean thats a decent shot.

 

Just as an update that 27 pounds for 559 whp was really the limit of one walboro! currently installing a full blown twin pump system. Still got allmost 8pounds of boost go! here we come 600 I hope....
