3) What I did at the track

As you can tell, I couldn't hook worth a shyt outta the hole.

Vehicle was uncapped from the cutouts running 92 octane with NX RACE Fuel Additive and fresh TR6 plugs.
Step-by-step on what I did on my run:

1) Drove through the water pit
(probably should have driven around it and reversed into the edge of it)
2) Put it in 2nd, compressed the brake and did my burnout for 5-7 seconds
(i know, install a line lock to save my rear pads/rotors)
3) Put it into 3rd gear and drive up to the starting line.
(in 3rd i personally got better results than in Drive)
4) Prestage lights, rev up to 2700rpm right before the tires begin to spin
5) Tree lights go down, mash the throttle and away we go spinning tires.

I'm happy that I improved with every run in every aspect....but I'm unhappy with my 60' times as they should be closer to 1.65 or so i figured. Any ideas on what i could have done or could do to achieve that goal in my 60' with my current setup of mods?

I did install the TR6 Plugs before this run as I was planning to run nitrous but chose not to since I can't even hook up properly. I think i need to spend A LOT more time working on that then adding more power. Could the TR6 plugs have hurt my performance as well versus using the TR55?

 

I stay out of the water completely.

 

i'll try that next time too. thanks for your reply

 

dude mine was the same way but yeah stay out of the water i ran 12.84@114.92 i really need to work on my launchs dont sweat it too much pal it will just get better with time

 

At some tracks you pretty much have to go through the water. I always go through the water spin em alittle in it get out then start burning them when they say go for it. Maybe the track you went to was wasnt prepped well that day or something. From your description it sounds like your doing everything ok. I usually use the et street slicks opposed to the drag radial version. I did drive my buddys car with the et street drag radials and I burned them up alot and it seemed to hook better. Here is a one of my track vids with a burnout I start out in first gear tach it up to 6k then manually shift to 2nd and hold it in 2nd for awhile then when im done I let out and throw it in 3rd and get ready to run. http://www.youtube.com/watch?v=wb5qetBBVfw

 

Our track has the ability to drive around the water pit so i'll be sure to give that a try. I thought maybe my D/R's at 255/50/16 were a little too small given that my daily 315/35/17's sumitomos spin for days. Granted the 315's dont have the sidewall the D/Rs have.

 

I just dont understand how you are running so slow. when my 99 ws6 had nothing but a vig 3200 stall and some 373 gears and m/t et streets. i was running 8.2-8.3 at 83mph with a 1.7 60ft. you should be running much faster with all your mods. do you shift the car your self or just put it in drive and go. because if i manually shift my car i run about 8.5 or so.

 

its called no traction outta the hole........ thought that was obvious.

and as stated in my first post, i leave it in 3rd gear and launch, no manual shifting, and my shift points are set at 6800 rpm due to my cam.

 

next time go around the water pit you will get a better time, your" 60 Foot Time : 2.122" you spining out of the hole

 

Definitely avoid the water, and i know you said et streets, but with my nitto's, you really got to heat em up. I made sure i had a good bit of rubber in the fenderwells, and i always launch better. Make sure they're warm, and since i haven't gotten to play with a stall since the good ole IROC, i say line it with about 3500 if it's a vig 3700!. You could definitely use some bigger DR's though if ya want. Just rememberm your 10-bolt is already screaming NO NO NO

 

Try leaving at 1300 rpm and flash the converter. This keeps from preloading the suspension and allows the rear end to squat and plant the tires. Adjust how hard you hit the gas pedal to match the track conditions. I regularly get 1.65-1.67 60fts on my 275/40/17 nittos.

I heat my tires leaving it in OD and get the mph to 70 mph for about 5 seconds. (Works with the nittos anyway) Try to back into the water if possible. Realise that some days the track conditions will just suck and you will not be able to hook. Avoid whell hop at all costs. Some days its just better to pack it up and go home before breaking something.

Practice, practice, practice.

Have fun.

everything done right except, i would not do my burnout in 2nd, these trans are built to start in 2nd when put 2nd, and burn them longer and get some gears 3.73. you may need a smaller wheel like 15' for more side wall.

 

i really appreciate your comments/suggestions and will apply them on Feb. 24th (the next time the track opens)

and gregsss, should i put it into 3rd or "D" for my burnout then?

 

Ya if you get some good tires cough slicks end cough and go back i guarantee you will be in teh 11's.

 

check my sig, dude...i had a 2.13 60' on my street tire run, also.

first off, i would suggest getting some mickey thompson et street DRAG RADIAL tires, not the bias ply as my experience with both is that the DR tire is MUCH better for an auto car.

a 5-7 second burnout is weak when you're on ANY kind of sticky tire. get those bitches hot. i would start my burnout and look for smoke in the mirror, when i saw smoke i would then hold the top of 2nd gear for 10 more seconds or so. on an unprepped track (street night at ICErp - any of those who have attended IRP can vouch) on street night, which always sucks for traction, i managed to cut 1.66-1.70 60' every pass on my m/t DRs.

on street tires i did a quick clean off, no water, then off the line i blipped the throttle to pitch weight and eased into it. it still wheelhopped a little bit, but ran a decent time nonetheless.

on a side note, that car seems to be trapping low for the given mods. i trapped 111 with a bad spin off the line, and consistent 109-110 with an *almost dead hook. (1.62-1.64 60')...w/bolt-ons @ 3,600 lb raceweight.

 

What was your tire pressure? Did you have like 30 lbs of air in those bad boys or something??

 

I am using 275 40 17 mt dr's right now. I have 19 lbs of pressure in them right now. I do have a little bit of trouble getting them to hook, but I can back in the water and spin them one turn and pull up to the edge of the water and power brake it for about 5-10 seconds and then let the car pull out while spinning. I pull 1.55-160 60's on motor and some high 1.4's launching on the bottle. I plan on getting some 255/50/16's...............................i think you will be ok, just heat your tires up enough. If the track prep is shitty you will have to waste more of your tires to hook.


Don't know how you launch, but it seems to me that if you torque up as much as you can you will hook better than if you torque up to 1200 or so and then flash. try both.

I did have on the Mickey Thompson ET Street Drag Radials. They are not the bias-ply version.

"What was your tire pressure? Did you have like 30 lbs of air in those bad boys or something??"

if this is directed towards me, you need to read my entire first post.

thanks

 

Whoops I totally missed that part of your post im sorry. Well anyway, how much tread are on those drag radials??? Are they beat to hell or something??? Something is deffentialy a miss with your time your trap speed is really high so that means its not a power problem its your 60' thats killing you. Was the track not prepped??? Were other cars having trouble hooking as well?? Its hard to see an auto with 255/50 drag radials having trouble hooking.

 

hey kaleopapa, what track u go to? mine opens up feb 24 too
