How to properly launch FWD
 
fairly simple post what and how you do to properly launch honda/integra or just any fwd. how to launch with drag radial ,slicks, and street tires. any knowledge i guess is better then wat i have(rev and dumn clutch:()please shed some light on this for me...thanks

On street tires it helps alot to feather it out. Dont' just dump it, and don't redline to launch. You just have to practice. Don't be trying to feather it out on a stock clutch though, it'll be gone in no time. Launching really cant be taught though, needs to be learned. Every car/engine/tranny setup will react different.

get a staging brake and preload the clutch

If running a turbo what I do, is a nice 2nd or 3rd gear burn out, have boost by gear and launch out of first with low boost and also have a two step so you can build boost before your launch, then dump the clutch and take off.

i launched my civic a little too hard a couple weekends ago and destroyed my final drive gear/counter shaft...it launched good but had wheel-hop...just as i was about to lift *BAM* too late...using bfg drag radials...i was hoping for a broken axle...those Raxles are pretty strong i guess.

**i would definitely "feather" the launch**

next upgrade will be some sort of traction bars...

Preload?????

Dead Bird 12-20-2008 01:21 PM

moparfan i had the same problem in my DA integra.
except my differential gave out at the launch.

Stock car.
Shitty Street tires.
5,500 launch cuz i was hopping at 5.
wanted to try it.
wanna get to the track and see what my numbers will be with the new setup.
anybody have a fire jacket i can borrow? pants too probably?

ICD 12-20-2008 10:03 PM

exactly why i need some good pointer before i go back to the track with something new and dont wana break.. just tryin to get pointed in the right direction

johnb20 12-20-2008 11:56 PM

get some 23 or 241/2 slicks put the air presure at 10psi do a good burn out and lunch at 7k and hold on!

ICD 12-21-2008 10:04 AM

^^ not going to be needing slicks just yet...mainly just d/r

CAPTAIN CAAAAAAAVEMAN 12-21-2008 11:39 AM

just get out there and practice, you could get all the tips in the world but they make any difference til you see what everything feels like....

when i used to run weekly at firebird your launches would have to change with how well or not so well they prepped the track.

its kind of like the road race/autoX fellers woud say, no replacement for seat time.

that one guy 12-21-2008 01:21 PM

one word: Preloading

ICD 12-22-2008 01:22 PM

Preloading=???
And to mr caveman I get way your but just tryn to get pointed in the right direction. On here alone u got already 3 different techniques which I will b tryn.just tryn to get out the rev And dumb

jdmhoe20 12-22-2008 02:35 PM

well just start to ease out of the clutch then once you feel it grab dump it and you wont spin as bad with any type of tire its just like all wheel drive cars and normally helps if you have 2 step or line lock whatever you wanna call it depends on if your older or not

2fst4door 12-22-2008 10:23 PM


know someone that does real good traction bars for cheap. pm if your interested

Mop 12-23-2008 01:39 AM

I think i read a while back about preloading. Before you light the staging lights, let off your clutch until you feel it grab. Keep your clutch in that position. Pull up your ebrake once you light up the staging lights. You can guess the rest.

michalo187 12-23-2008 02:53 AM

:you rock: this is almost exactly to what I do, I have launch control with my hondata build up some boost take off and shift to second when its burning out and keep the tires burning. At the light I pull the handbrake then pull the clutch out until i feel the car move a bit an then take off at the 3rd yellow light because by the time everything reacts it will be green and you will have a good reaction time, it works everytime for me. I ran bf goodrich 215/60/14 drag radials. Click on the link on my sig to see the video of my run, once i get it running i will post a video of my burnout at the track hopefully by IFO.

Also watch these two videos they give great demos.

whats preloading

bumpstick 12-23-2008 12:37 PM

all the shit everybody else just said. you know how you can hold your car on a hill or at a stoplight, with a little bit of throttle and letting out the clutch real slowly? it doesn't go forward and it doesn't roll backwards? That's how you do it. A pound of pressure less or more and your car will roll back or take off.

ICD 12-23-2008 02:22 PM

:thumbup:

johnb20 12-23-2008 10:17 PM

if your not using slick for drag racing your was your time.its almost impossible to not peel out on a fwd.if you feathering your clutch your burning it up bad!! full throttle all the way!! no bs feathering here

JDM Jon 12-23-2008 11:33 PM

just depends on ur car and motor man
and lots of practice

preloading is key like everyone else said
pretty simple

Hopeless EP3 12-24-2008 05:59 AM

I actually have a question about preloading so I yank the ebrake up and find the sweet spot with the clutch right... so after that do I rev it to my launching point which is 5000-5500 rpm or what do I do? wouldnt my car start moving even tho I have the ebrake up??


Noob question but I wouldnt know the answer unless I ask

michalo187 12-24-2008 08:19 AM

you gotta keep the clutch half engaged if not yes it will start rolling, so you just gotta find that sweet spot.

bumpstick 12-24-2008 10:52 AM

you shouldn't rev that high if you're on street tires, cuz when you dump the wheels are just gonna spin or you're going to hook up and break an axle. it'll be a bitch getting home without a spare. everytime you are at a stoplight out on the street, practice preloading and figure out at what rpm does your car pull forward without smoking the tires or bogging down. granted this rpm point will change when you're at the track cuz it's a different surface but it will give you a good starting point.

Thank you good info right here

moparfan 12-26-2008 06:55 AM

pm'd you...

redwidow 12-26-2008 12:49 PM

if you have a twin disc clutch and 2 staging with 22 psi i recomend not dumping the clutch:) or do and just have axels on stand by..i sheard the DS axel by the rubber boot closer to the intermediate shaft..chitty

michalo187 12-26-2008 03:18 PM

:cool: that must have be crazy
