I still firmly believe these cars behave significantly different when you have 100mph air blowing through the front grills. I just don't think dynos necessary show replicate these conditions, and cars may react differently on the dyno then the street. For example, a DCI would be great on a open hood dyno, but in everyday driving, you might see a disadvantage sucking in that hot air under the hood.

Sometimes you just have to do things unconventionally. Do you realize all my record breaking runs were done with avoiding the water box and absolutely no warm-up burn out? I just do a light 1/2 second scrub, and I'm off.

You see, I figure with no LSD, you can't evenly heat up the tires anyways.

Both tires spin like a lsd on burn out,so you can heat them up a little if you want before your launch.And when you launch if you get any wheel spin,both rear tires will spin.

Not even heating your tires? Impressive indeed.

I understand how anti-dyno you are... why not use the dyno to prove your point then? Dyno as you are, the same way you make these fast runs (race gas + 17-18 psi) with the stock airbox.

Start really modding your car and dyno again, and then get back on the track.

The comparison will be very interesting.

so hotrod are you ever going to add some bolt-on's, at least some dp's? I think you could hit 11.5's with dp's and an lsd.. that would be SICK!!

Yup the ET Streets were definitely a handful. Probably unstable due to mixing radials with bias ply. But yes I absolutely did no tire heating and half the runs were at 28psi in the hoosiers!

you can heat both tires warren, give it a shot. If you ever hit one of Terry's unreal 60 ft times you will put down a serious et.

lol you and your 25+ psi! Mine are always at 15psi... I bet if you were a 6mt you would need a lot less psi because the launches have to be really high... I drop the clutch at about 4300 rpms

I knew it! I have to test it out next time but from my experience, DRs that we use seem to perform better at higher pressures: trap and ET times were better with higher pressure. Go figure.

I thought I had them set at around 24psi. But after doing some runs and being out in the hot sun, I believe the pressure went up.

Interesting that they went up that much. I measured after just 1 run and they went up 2 psi in each tire. (23 to 25 in 60F).

That trap speed is insane. He has to be making at least mid 400's to the wheel..

I had a video of me doing a warm up burn out, only one tire was smoking. And many times, I didn't see any advantage of going through the waterbox in relation to my ETs. But mainly I really enjoy pulling off some decent ETs without burn up the tread on my DRs. But yes, if I properly heated up the tires, (or a super sticky track), with a 1.66 60' time, I woiuld probably be getting a 11.5x qtr mile.
