M/T Drag Radial's are the

just curious, are you worried about the IRS blowing up? Also how much HP are you putting down?

With an IRS brace and good sticky tires on a 500 RWHP cobra you shouldn't have any problems unless it starts to hop and you don't get out of it. I have found that drag radials can hop like a mother at the track.

Yup. If they hop bad, just abort the run. Save the car, the time would be poor anyway.

A smooth clutch release technique will allow that IRS to tolerate alot of Hp.

Be quick, but don't snap it out like you would doing a burnout or stunt driving (drifting). A rapid, but controlled release of the pedal is the trick while feeding in the throttle to maintain the Rpm.

vicious781, No...never worried about the solid axle in the Mach1 that had 900runs in it before the spider gears lost it's teeth or now with the irs.

The stickier the tires, the less chances in getting wheel hop. Solid Axles get wheel hop on bad tires and that Concept applies with the IRS.

Now, folks do blow things up, but in honesty, it comes down to technic...IMHO. Yes, some have blown the half shafts & axles, even to the point that they are scared and will post in such fashion. I just say review the poster & see how many runs that they have made, just to weed out the here sayers.

M/T DR's still get hop...for some odd reason it is always my 1st runs. Maybe I just need to do a LONG LONG burnout on my 1st and lesser ones there after, since I wont be happy if they only last me 40 runs. That would be like 60 shy of what ET Street can get me.

Here are two of my best slips. Yellow one is the one I lost by breaking out .002!!! He was a newbie so I could of lifted a LOT sooner. Track was stuck and I can usually tell by my R/T's.

Car# P734.

Screw the race, you shoulda just got the slip for that ET! Hell, you stomped on the brakes so hard you lost what would have been a full ten miles an hour. That would have equalled on hell of a low ET!

That was a 11.6xx pass, easy.

LOL!! NOT EVEN CLOSE! 1/8th MPH shows it would of been a good 1/4th MPH, but I was already off at the 1000' ET from the PB.

11.85 or so....nothing more then that.

BTW: I just lifted on the 1st MPH Calculator Cone and let the motor slow down in 4th gear. Still like 60' to travel to the final Cone, so that is why it shows a low MPH.

Your 1000 time was off a tick, but you had better Mph. Either way, you are making some impressive power to pull that speed with your mods.
