Default burnout bfg drag radials

hey guys, i am preparing to head to the track in a few days. Car is a full interior 94 integra gsr . This is my first time going. I jus completed an all motor b20vtec . Power on dynojet is 224 whp and 156 tq . I have BFG drag radials 225/50-r15 inflated to 12psi on some heavy OEM rims. I was jus wondering , after rolling through the water , for my kind of power , should i do a 1st gear burnout or a 2nd gear burnout ?

i also have a question about the launch. I read about preloading but i still didnt understand what it means to feather. Do you mean to let go of the clutch slow ? , or does it mean to drop the clutch and play with the throttle of the gas ?

thanks

I used to run DR's all the time 16 psi is what i found worked. 2nd gear burt outs for sure. I slip the clutch until i feel the car move then soon as it moves let it out all the way. HTH Rob

16 psi ? what rpm did u drop the clutch at for the 2nd gear burnout ? .. is it still necessary to preload while burning out ? How much power were u making anyway when u were using the drag radials ? .. thanks !!

ive run around 30 passes on bfg's.


10 psi cold, goes up to 13 or 14 after burnout.

2nd gear in the water box with the ebrake up. do the burnout in 2ndd gear keep the revs up pretty good. release the ebrake to pull up to the line.

i never had any crazy 60ft's, but did cut a consistant 2.0 for the the second half of last summer. this was making between 300 and 330 whp

should be running the 205 instead of the 225's......

2nd gear burn out and heat them suckas up.. BFG's like it HOT....

what kind of advantage is there to use the 205's instead of the 225's ?

out of curiousity , do most cars , even like stock B-series do 2nd gear burnouts ? i mean , isnt it neccessary to be making decent power to do a 2nd gear burnout instead of bogging ? like blackeg is making 330whp doing this 2nd gear burnout , but i am only making about 220 whp. thanks for the replies

Don't make it too complicated, just do a LONG 1st gear burnout, and like mentioned before let the clutch out until the car starts moving then let it out all the way I only have the 205-50's and cut consistant 1.95 60's. I just think my car is a good launcher though. BTW this is on a 12.9 sec turbo del sol ( stock motor)

sorry to ajck your thread but i was always wondering how you are supposed to rev high while doing a burnout when you have a 2 step set in th lower rpm's using street slicks?

yes with a 2nd gear burn out you will run a higher MPH which will get the tires HOTTER.... the advantage of YOU running the 205's is that they are 22" while the 225's are a 23.9"......
ive ran both on my old 215whp hatch and the 205's were better for the 1/4..altho i was still getting 1.8's with both sets...

so just roll into the water box put it in 2nd rev it up ad let the clutch out the tires will spin due to the water and then just let it loose..... maintain it in the upper revs.... dont forget to jank that Ebrake up!

Oic .. well , i m concerned about the 1st gear burnout because i read feedbacks with people saying that it hits the rev limiter without actually spinning fast enough to heat up the tires or even smoke at all .

ahh , makes sense .. the bigger tires must have been heavier and gave u slightly longer gears which is probably why the 1/4 was slower a little.

i dont get it tho , u said roll into the water box ? .. do i do the burnout there , or roll out of it and then put it into 2nd ?

2nd gear burnout for sure. I did them back when I had 146whp.

oic .. is doing a 2nd gear burnout any more harsh on the drivetrain compared to a 1st gear burnout ?

on the water box , do i jus roll through it slowly and it ll be wet enough ?

thanks for the responses !!

im not 100% but i wouldnt think so. it would be easier to keep the rpms where you want while doing the burnout, therefore not slamming the limiter as much....

no it isnt since your tires are wet they will spin freely.....

what would be wrong with using the bfg's with NO burnout. Reason i say this is burnouts are bad bad for the drivetrain (as are the super sticky launches). but wouldn't the DR's still be better than street tires?

gsr crx at the track last weekend had bfg's (225's i think), and he didn't even know how to burn them out, just did a quick clearing, and still pulled easy 2.0x-2.1x 60' with wimpy 3krpm launches and no squealing btw shifts.

i went over an checked his tires out, they were sticky like glue, i could sink a finger nail in, and he had none of the DR rubber bits smeared all up the side of his car. ?

his best time that i saw was 13.69 @101.8xmph in a full weight crx w/jdm gsr w/early b16 trans/lsd, and no 'burnout'

yes u can use them without heating them up but if that was the case why waste your $ on getting BFG's if you can get 2.0-2.1's on any ol tire with a lil driving skill

how are burnouts bad for the drivetrain??? the car should loose traction almost immediately

i dunno. it just strikes me as not a real healthy thing to rev to car up to near redline and pop the clutch hard, and then just sit there wailing on it.

i've seen some stock looking newer mustangs, on street tires even, blow their trannies at the line following a big burnout. probably cooked somthing. can't be good. not that any part of drag racing is 'good' for the car

the added traction at the line following the burnout would hit the drivetrain and acels harder too.

i'm not there to break any world records, i just want to get the need for speed out of my system for a month, and have a little fun without killing my car, or my expensive tires.

well i've hit 2.1X 60' 3 times with my setup, once last weekend, but its almost a fluke, and i'm not getting better. to get better i'd have to beat on the clutch harder and perhaps try some powershifting....naaah.

I'm at the point now where i'm wearing down my street tires enough that i might as well get some 'track only' front tires and rims, and get some good milage/treadlife tires for the street. And if i go that far, i might as well get some tires meant for drag racing, but i still don't want to beat the snort out of my car and expensive tires any more than i have to to get some half decent 60's.

Easy 2.1 60', and no more breaking loose shifting to second and third would be mint. i just want to feather it out at 4500rpms and go..

bro from the sounds of it i dont think you are cut for racing if your that worried about "punishing" your car.....

i have been racing all my life and i have yet to break a axle,tranny off the line.... blown a few motors, shattered a few clutches but nothing i couldnt handle

hehe...

well, i like to have a little bit of fun a few times a year, but conservatively.

I just installed a brand new itr tranny last month because my gsr trans wouldn't go into reverse anymore, after simply missing a 5th gear upshift, while chasing down a wrx on the street. made me realize how delicate these machines 'can' be, and expensive

not really soft but they can take a serious beating....

when your in the water box the tires will spin freely unlike if you were to dry hop
