To save myself from sending so many PM's, yes I have successfully been running an LRP x12 17.5 in TC on asphalt and carpet rubber tires. Of course, like most you will only use part of it or you'll try to adapt it to your 5.6FDR and come back and say it doesn't work for you...LOL (j/k Dusttt)
LRP x12 17.5
FDR- 6.8 to 7.2 for asphalt, I stayed with 7.2 on carpet
motor- x-10 insert
ramp 2 or 3- with slow turns / heavy low RPM loads 3 will fade
delay- .2 or .3- faster ur entering straight, earlier u can bring it in
start RPM- 5000
end RPM- 13000 - 15000 (alter this to help control heat. lower= faster boost increase / little more heat)
ALWAYS check ur temp at the 2 or 3 minute mark with x12 motors on first run or after any change. They aren't all the same and some get hotter much quicker. Some may like 1 or 2 teeth less, some may like up to 3 or 4 teeth more- u have to find that out on your own, but shoot for around 198F (or less) with no fan after 6 min. I practice/tune with turbo on 8 and ramp 2. Temps are 155-160 outdoors w/no fan. When I'm in that range I know I can turn the turbo up a bump and or increase ramp, run the fan and I'm golden.
Last quick tip- if you're having trouble with the turbo coming in while in the infield and giving you a "shot" that messes u up for the next turn, do like Obama and rob Peter to pay Paul by adding 3 or 4 to your boost and taking away 2 or 3 from your turbo. You can also move the delay up or down one tenth. I would much rather give up 1 car length on the back straight than give up 3 or 4 because I overshoot a certain infield turn every time.
