for those of you skilled enough to pull 2.1 or even 2.0 60' time on street tires, do you do burn outs or no?

how about burn outs for the drag radials, i imagine they benefit more...

 

i don't think this will be of any help to you, but last weekend i managed to pull several 2.0 60' times on 215/60/14 bfg drag radials. i rolled out of the hole, or dropped the clutch at 6K and still got the same result!

 

I find on street tires it's best to just do a quick spin to get the rocks and dirt off...... drop the psi to around 20-22psi.
Drag radials I heat alittle air down to 17psi
Slicks heat them until they start pulling the car. HTH Rob

good advise there.............doin a burnout on street tires is more or less to clean off all the crap that your tires picked up in the pits/lanes. no need to make a smoke show out of the ordeal, just spin 'em a little and do your thing

I've run on BFG 205/50/15 and 225/50/15 Drag Radials. With the 205's, I would use the two-step on Neptune, and have it set to 5500rpm, get a nasty burnout, and cut consistant 1.9 60fts. I ran the tires at 11lbs of pressure.

Last night I finally got the 225's dialed in, and again using the two step I do my burnout with holding the two step at 6500rpms, then launch at the line at 6500rpms and I was cutting consistant 1.8 60ft's. I run the tires at 10.5lbs of pressure. My 1/8 mile times with me driving the car like described--&gt;

RT-------60'-------330-------MPH-------1/8-------MPH
.372----1.840----5.205-----71.23-----7.843-----93.47
.199----1.874----5.316-----70.11-----7.965-----92.40
.214----1.848----5.195-----72.34-----7.917-----90.06&lt;--Small problem w/ 3rd gear
.282----1.931----5.205-----73.14-----7.847-----93.67

 

Please share launch technique. I've cut 1.9's but not on a very consistent basis. Mostly
4 out of 10 are 1.9's the rest are 2.0's in a 181whp all motor car. My question is, when you release the clutch with the 2-step at 6500rpm, do you lay in the throttle or feather it to control wheelspin? Also, what's ypur whp? 1.84' on drag radials is admirable. Thanx.

The car is a 00 Si weighting 2630 with me in it and 1/2 tank of gas. The car is making 396whp/268trq on a 84.5mm b16 with gt35e. As far as launching goes, from the sec the second staging light comes on it's pedal to the floor and clutch all the way in. On a protree I dump the clutch as soon as I see amber, and on a bracket tree I dump the clutch as soon as I see the third amber. I don't slip the clutch at all, just dump it and let the tires due the rest.

Do you preload the clutch?

Congrats on those 1.8s with the BFGs...

Thanks. To be honest, not really following what you mean by preloading the clutch. Would you mind expanding on that?

 

After you dump the clutch do you still use full throttle or feather it to minimize wheelspin? I was driving a DC2 making around 500whp on 225's and on 235's and blew the tires off on both.

Sure thing... On the line, you hold the E-brake and slowly let out the clutch until it preloads the whole car. Then when the light drops you throw down the brake and drop the clutch.

Oh gotcha....only time I use the E-brake is when I do my burnouts. Pull E-Brake straight up, rev the car to 6500rpm, drop the clutch in second gear, then pull to the line.....at the line I just put the pedal to the floor, let the two step do it's thing at 6500rpm and drop the clutch when the amber comes on. No preloading of the clutch...Thanks for explaining that.

good info guys... never been to the track and this helped

 

I would use the two-step on Neptune, and have it set to 5500rpm

Hi guys,
sorry for the noob question, but what is this suppose to be? is it a type line lock?

It's a standalone mangement system.

 

best to think of Neptune as Hondata stage4+; more features, less price. what hondata for Honda OBD-1 ECU's was suppose to be, but costing a lot less. you can only get Neptune at some of the best Honda tuners around the country...
