Not considering the difficulty in getting traction at lower temperatures, what do most of you guys think is the low temperature limit to safely crank on an "off-road" HiPo engine to 6K - 7K rpms?Because of most of us using aluminum parts (which shrinks quite a bit when cold) and that we're apt to have fairly loose 0.025" - 0.035" bearing clearances, I'm thinking that running under 50*F would dramatically increase the risk of hurting the engine.... What's your limit???????? Ryan

I have raced at some of the local drag stricks when the outside temp was barely above 30*.As long as the engine is warmed up properly along with the transmission and rear end, the low temps should have very little bearing on the clearances. FYI, wind chill is not related to anything that doesn't perspire. Metal at 30* in a 90mph wind is still 30*.

Warmed up to 120 degrees or better, and with the rest of the drive train warm, I have raced in 30 degre weather with no adverse effects. Traction was a serious probelm though. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00, '01, & '02 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

I feel that so long as the motor and related drivetrain is warmed well, I would run it. Traction (or lack of) on the other hand would be of more concern to me.

Well Guys.... They're calling for a HIGH of 49*F this weekend. However, by using a proper warm-up makes a bunch of sense... Thanks for your experience & advice, Guys!Regarding traction,,,, I've been told that the ideal traction temp for slicks and/or track surface is 90*F. Even with a long burnout, I'm not sure I can get the slicks warm enough to get any decent 60'ers...... Ryan

I hope the track has some propane blow torches. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00, '01, & '02 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

I raced at Muncie Dragway last weekend and the temp was in the low 30s in the evening. I had to scrap frost off of my truck windows after the race. :------------------ Ben Grabber Green '70 Mach I 351C 4V Robbin Egg Blue '79 Fairmont 351C 4V

Ice racers don't seem to blow up too much stuff. It's simply a matter of not running hard while stone cold... you may need to spend more time warming the car up, run thru the gears on jackstands, etc.

Good Point, TomP! Alex, regarding propane torches.... I highly doubt they'd bring them out. (1) because it's the last day the track will be open for '02; (2) because it's just a TnT outing; (3) since Mid-Michigan Motorplex turned NHRA, the attention to the track surface has gone down.

You might want to run your car at low speed around the pit a few times then shut it down to take advantage of the cooling effect on the intake for more HP. Not that the lack of traction will require more power, but it will save on fuel. The engine will stay warm for quite a while after you shut down.

Tell the "old battle axe" that we'll give her some left over discount coupons to Maxfield's if she preps the track. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00, '01, & '02 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

26 degrees last saturday. Corrected altitude -600 feet below sea level. Sixty foot times where not the best I ever had, but close. Lane to lane a bit off. A long burnout, not recommended. Ran the fastest pass ever 7.016 with a 1.437 60'. Air pressure in tire a little lower than I would have liked but I made it hook and it did not skate around on the top end.
