How to Launch your car perfectly using a Clutch Release Valve - Jay's Tech Tips

- Consistently launching your car perfectly every time can be a difficult skill to master. The hard part is that you can break a lot of expensive parts while you are learning the sill, so the learning process can get very expensive and unaffordable.
Launching too hard can break parts or spin the tires, launching too soft will ruin your race.
Using a hydraulic valve between the clutch pedal and the slave cylinder on the transmission can control the speed that the clutch releases, and do it at the same speed every time, regardless of how your foot comes off the clutch pedal.
There is a mechanical version that slows the clutch pedal release in every gear change, or an electronic model that can be configured to only slow the clutch release on the launch, and then allow normal clutch operation in the following gear changes on your pass.
Using a clutch release valve can take the inconsistency out of your launch, which will give you more confidence to win races.
Didnt know that existed. Thanks guys
Love these tech tips!
I love these tech tips. Thanks for putting your time and effort into them making these videos!
Loved this one. Thanks Jay.
I knew this thing existed but never fully understood until this tech. Thanks guys for informing me.
plane simplicity at its best!
What's the name of that intro song??? btw love the tech tips.
I'm not a pro drag racer but, when I do start with my friends (on road without incline) while in neutral, release brake... clutch down, while putting it in first gear, I at the same time press the gas pedal to 2000 RPM, +/- 100 RPM, I keep gas pedal in place because I lean my right foot on the side wall so I get consistent rpm, drop clutch till the release moment, when it starts to move I press more gas and drop the clutch fully in like 0.4 seconds, so I don't stall or burn it. Anyone with manual car can do it, all you need is to practice a few times till you feel the car.
P.S. Audi A6 (C5) Quattro 2.5 TDI 180hp
P.S.S sorry for not the best English.
Pretty good English dude !
+Vlad Mitrofan Yeah, but this is aimed at cars with a lot more power (think 600Hp+) which are way more harder to launch than a 180Hp car.
Yeah that's fine for your 180 crank horsepower car. But tell me that works consistently with 800+ wheel horsepower.
This guy is so dope, I wouldn't mind meeting him in person and working with him in the shop for a day!
That's neat, never seen one before. keep em coming Real Street! !!
that's a cool little device! take care
That's sick! never knew that existed!
thanks for the great tips jay, keep up the great work and amazing cars
The factory mechanical ClutchDelayValve (CDV) was one of the first things I removed off my BMW :-D (recommended!) You don't want the delay in every gear change. It also makes daily driving quite uncomfortable..especially with cold fluids.
But I get why it could be useful in drag racing for getting off the line although I'd only get the electronic system.
Great Video REAL St.....!
I wonder if they installed one of these on the TRC Supra?? that car launches hard on digs 👌
Cool, never heard of that. Maybe next time have a link to the product but great video!

+Mark H always check out the real st. website
ɷ Heeeey Friendss I Have F0undddd W0roking Online Hacck Visit : - t.co/DpGBarCUaA
do those powerglide gearboxes have something like this built in?
excellent vid!! more of the same please!
you learn something everyday
Where can i buy it? Link to the product please?
Awesome vid'
Will this work on a motorcycle with a hydraulic clutch?
I never knew thank you
I sure could use one of these..
what would u use to clean the intercooler fins on the outside?
can you use these on cable clutches or only hydraulic
Awesome pure awesome
hi i have a question!! sorry my english to bad!! this module if i put to my car helps to protect the axle from violents launchs when y drop the cluch?? i have an subaru impreza sti type ra jdm with he stock axle and it to hard to find the parts for the car i live en paraguay south america
You guys need to run that Colt on the streets once you have it all dialed in.My ears are still ringing from the Dyno video!
Two thumbs up!
thanks
Will this fit in my Honda?
What's the name of the instrumental played in the intro?
What car was that in the video
How much?
The problem is shifting through gears while going down the track
Does it work with double plate clutch?
yes.
Interesting
where can you order these parts?
Any one else is seeing the bug at 1:37?
Fuck i wish i saw your comment before i wasted my precious time making a comment about the bug lol.
Can you fuse your clutch if you set the release too slow?
Probably
Talk to me about hitmaster!
Launch control for manual cars!
That Dsm left fucking hard damn
I think these still wont get you the best times like knowing your car and getting it fine tuned with foot than valves, I think the delay is half a second and for some its alot + if you change clutch change drive shaft too so it wont break. 1000+ hp cars that drag race have aftermarket shafts and no clutch valves, BUT I REALLY like it since I drive automatic I can use this in a manual for my future cars.
I gained "magic foot" by simply buying a clutch rated at way more house power then the engine could produce. Admittedly I did kill a couple of drive lines. Magic foot is not free.
Isn't this going to wear the clutch out real quick?
slipping the clutch will always shorten it's life but it's better than shocking the drive train, breaking differentials, etc
Or you can just practice launching a few times a day....
+cory lepire The risk of breakage is still there every time so you are only playing a numbers game and speeding up your time for breaking something. The valve once set will have you consistent in the correct way. To each their own. Of course my comment is towards someone who isn't very good at launching only.
if spent 15 to 20k on a build you don't want to risk blowing things up.
+cory lepire No one is perfect, regardless of how much you practice there will be differences in how fast you release every single time.
song name on begining?
Good way to avoid burning your clutch... well kind of, lol.
Driver mod is way cheaper though...
Driver mod lol
at the end drivers will watch their cars race by their own.....damn..where are we going..
Am I the only person that focused on the bug crawling on the wall in the background?
or, you could just make your car drive itself and watch from the sidelines.... ummm NO WAY! I'd rather be in control. I understand the benefits from a racers stand point but still, where do you draw the line?. own it
It's called a fuckin damper. 240s have them stock, they suck!
if you own a GTR you don't need to watch this video
or just learn to drive a fucking manual like nearly everyone does in england. it takes practice to do as its not really easy or everyone would be drag racers
+The Channel of Stuff that's fine and good until you're making like 750+ hp (599 kw) to the wheels like most every single car Real Street makes. No matter how good you are you will break something eventually.
+The Channel of Stuff There's a big difference between a 100~hp econobox with a sprung, solid disc OE clutch and a 700+hp race car with an unsprung 3/4/5/6 puck clutch.
i'm not on about high end dude. like the car he tested it in, people will use it in their hondas
I'm from the UK and i have a mr2 mk2 that i use for track days and sometimes events at santa pod...
+The Channel of Stuff The car they tested in this video makes over 800hp...
so talent doesnt count any more...win races by wallet then..

This is why i subscribe these are cool to watch. Those 1,000hp supra vs gsxr are pretty boring. Or girl reacts to 1000 gtr.. Yawn.
what would u use to clean the intercooler fins on the outside?
