Default Proper launch method for my kind of power?

Hey ya'll. I"ve never been to the track but I want to be prepared before I go. I'm running street tires (195/50-15). I have a 96 hatchback with a b18c1 engine, i/h/e, and a zex nitrous 65 shot. i'm prolly makin about 250 hp with the nitrous. how should i burn-out (should i even?) and how should i launch?

do a burn out to heat the tires for optimal traction. On my turbo b18c DC2, I launch from 5k rpm. Traction is pretty shitty in 1st and 2nd but then from there it hauls ***. Thank god for the boost controller.

Doing a extended burnout on street tires is useless. Do a short burnout to clear any rocks and water off the tires and to build up a small mount of heat then stage.

i doubt you are around 250 w/a stock gsr and a 65 shot......just do a lite burn out and then stage and dump it around 5500 or so.just to get you over the hump,then jam them gears and see what times you can lay down....good luck?

1 pull in the water box"do a lite haze on the tires and roll out"

2 roll up to the tree slowly and wait for the first light to come on,then just barely roll forward till the 2nd light comes on"then you are fully staged"

3 yellow lights start"leave on the thrid light as it gets to it's brighest point" key to a good reaction time.....or you could just wait till the 3rd light comes on and say 1 and then go.

there are also other ways to get better reaction times,but i don't think your ready for that yet.


let me know how you do.

What type of tires are you using?
if you are using true street tires, doing a burn out will not help at all... This will just wear out your tires... you will need to launch at a low rpm or you will loose traction... you will have to find the sweet spot of your car for launch rpm...
If you are using drag radials, do a burn out but not too long... Probrably a 5-6 sec burn out will do... with drag radials play with the tire psi and rpm to find your cars sweet spot...

5500 Rpms if your on drag slicks, otherwise thats way too much... plus you dont want to just dump the clutch, that will cause extreme shock to the drive train and eventualy break transmission parts and/or drive shafts... if your using slicks, you want to do a bigger burn out, around 10sec long or so...

r u launching ont he juice?? You may be better off just launching at 5,500 or 6,000 off the bottle and trying for about a 2.1 60ft. Then just spray going into 2nd gear.

Also, if u are launching on the bottle try not to bog out at the line. (shouldnt be a big prob w/o slicks)

you don't want to instantly hook tho....you want to spin just a little then go.
as far as dumping it....."pre engauge" sorry about that.

5000-6000rpm on street tires is asking for no traction... well that is unless you only have 80 whp...

I understand what you are saying, but with that low hp, as long as you pre load the transmission, you shouldnt have to worry about breaking parts if you hook right off the line.. plus, reving to 3000rpm will give alittle spin off the line, especialy if he is sprayin off the line...
remember he said he is on street tires, most likely low profile tires or stock sized tires that will not hook up that well...

i guess it all depends on track conditions.5500 may be just a little to high...but you do not want to bog coming off the lie.


we have a ek hatch back w/built b20 w/gsr head...spraying 300,and we spin a little and we pull 1.6 60's.....and that is w/24.5 slicks.but it is sure is fun to drive and it's a hand full.i can just imagine what my 2.4L f24 w/t72 bb and nos pro race fogger is gonna be like.

thanks for da help guys. so to do a PROPER burnout you: lock the e-brake, have it in first, rev to ~2000 and dump da clutch then go to full throttle?

BTW: wut is "pre-engaging the transmission?"

5000 to 6000 is not too high for launching that motor if u slip the clutch instead of just dumping it.

1, even if he did have 250 hp 5000+ rpm is way too high with his 195/50-15 street tires.
2, I have the exact same size tires on my commuter car, with a stock motor that has 98whp at 3500+ rpm it will spin the tires like nothing...

Just watch a few people stage to see what they do, thats what i did. To burn out just rev to like 7k and let out the clutch and keep the revs around redline.

i said launch off of the nitrous, and w/o nitrous 5,500 is def not too high for a b18c1 to launch at.

W/ the nitrous on I cant begin to speculate but i agree thats probably too high.

1. dont go through the water box.
2. street tires are not supposed to get hot. dont burn off at all.
3. stage
4. go
5. see what you trap because you won't pull a good 1/4 w/o slicks in a one tire fire FWD car.

do not use water box with street tires. water get into treads and get water on the track, which makes it suck for the guys running slicks.

You havent been to many sanctioned events then have you?

to clear things up, I said around 10 sec., i aim to sit in the water box for 10 sec. each burn out i do, and usualy ends up being around 9 sec, plus how ever long i carry out of the water box...

Default Re: Proper launch method for my kind of power? (Tippyman98)

are you planning on sprayin off the line?? cause if so, good luck! it takes alot of passes to get the launch right, with street tires that is. Last year my setup was civic eg vx b18c1 baseline 153whp@7600
i/h/e
jg edelbrock im
skunk2 stage2 cams
supertech valvetrain 188whp@8400 132tq@6600
zex dry 75shot
(hondata tuned,mustang dyno) 262whp@8400 210tq@5300
best 60'ft. on street tires (205/55/15) 2.2sec
best 60'ft. w/20" slicks 1.85! and thats w/ 20"slicks! i would spray off the line and the slicks would just pull me through. i couldnt break into the 13's for nothin on street tires, my best was 14.1@101. On the slicks my best was 13.3@100 times seem slow im 5500ft. above sea
but if your running street tires, i suggest you flip the switch right when you shifdt to 2nd.
