I don't exactly agree.....it may not be "instant" but it will engage A LOT quicker than 30ft on a healthy clutch. Otherwise your clutch would be toast in only a few passes......actually in truth if it is already slipping for 30ft your clutch is already toast

The momentum of the engine spinning (5-6K RPM) is what keeps the car from stalling. You usually either spin the slicks or the RPMs will drop a little and then go up as speed increases etc.

Just my 2 cents.

 

Look at it this way...the 60' is basically all of first gear for most cars. If you're on slicks, launching from 5000rpms...and you hook and don't bog, eventually the speed of your engine has to meet the speed of your wheels (full clutch engagement), on a good launch, the speed your car is going when the clutch fully engages should be well into the powerband to avoid bogging. This would be about halfway through first gear for most cars. Since most cars travel through first gear in the first 60' halfway through first gear is.......about 30'.

I also disagree with the clutch being toast if it slips for 30' since on a good launch...this is just over a half second of slipping..which is very minimal.

 

But during that time the clutch has grabbed and is pulling the engine speed down...not slipping.

I guess it depends on the car....I'm not doing launches on slicks in my car (due to obvious rearend life issues) but my first gear goes waaaaaaay past the 60 ft...52ish mph.

 

try 11.008 @ 119 w/ 1.4 60 ft. vw's with half the power you have.


also you know the reason i have a "14 second vw"?

one, this is my daily driver. with 5 grand i can make 500+ whp on STOCK BOTTOM END.

two, i don't have 5 grand to dump into my daily driver right now

three, i'm 19, there's plenty of time left for me to mod my daily driver.

and four, i have a project car so look out!

it takes less than a foot for the clutch to be fully engaged. re-read my previous post. if you still fail to believe it, go ask some other well-known professional drag racers, since you won't believe my dad's information. if you want i'll even put you in touch with a few.

 

correct. instant engagement on a good clutch. spin, bog or stall. as i stated before.

 

Umm..if the clutch is "pulling the engine speed down" it's slipping until the engine speed matches the speed of the wheels. Simple facts here. If the engine speed matches the speed of the wheels almost instantly...you will either spin, bog or stall...leading to a REALLY REALLY sh!tty 60' time.

I don't understand how you guys think that a clutch FULLY engaging at ONE foot leads to a good 60' on slicks. It simply does not work that way. You'd have to pull out of the hole at almost zero RPMs...

 

A Z has gone 6's...what's your point??? Nevermind other people's cars..if you're going to make a point at least use your OWN CAR to make it.

So you don't have 5 grand and you don't have 500whp...so why is it even worth talking about?

You're 19, cocky, and ignorant....great combo. Shoot for the stars!

I'm a billionaire...so look out!

Daddy, daddy...some guy on the internet doesn't believe the stuff that you tell me. Please set him straight since you are the end all and be all GOD of all that is automobiles!

Read my post previous to this to see how much of an idiot you look like.

 

DING DING DING...and NONE OF THOSE LEAD TO A GOOD 60' TIME.

Reading comprehension OWNS you.

 

who's the cocky and ignorant one here? not i. i know what my car and beat and can't.

who's the one insulting the other? not i. as usual with people on forums, when you get tired of discussing the topic, you move to insulting someone with any information you can get about them. you probably wouldn't have even made the comment about my car if i had some 1/4 mile time faster than yours down in my sig.

i have nothing against you, i'm just stating how your information you are giving is wrong.

ANYWAYS BACK ON ****ING TOPIC.

correct. instant engagement on a good clutch. spin, bog or stall. as i stated before.

i left out something, it was late...the best launches come when you can completely drop the clutch, as i call it, the sweet spot, and no bogging, spinning, w/e. like raptorbh12 did. he just ripped out of the hole. depending on the clutch, amount of power, and traction would depend on whether or not the clutch slips. too much traction, too strong of a clutch and a decent amount of power? you'll blow something apart. most likely an axle or differential. the clutch and tires are not the only thing that gives. we're amazed raptorbh12 hasn't blown something out yet.

you think guys with a 1.0 60 ft. have a slipping clutch for the first 30 ft.? no. they have tons of runs perfecting their launches so that their clutch and tires aren't slipping/spinning and they get the perfect launch.

 

You started it when you laughed twice at my comments. Just giving a litte back.

How is my information WRONG since we are now arguing about two totally different things. I'm talking about a GOOD launch with FULL traction and NO bogging...and you're talking about bogging, spinning or stalling.

So how does this add up to a good 60'? First it was...a clutch engages instantly on a dump no matter what. Now it's "good clutch". You keep changing what you're saying.

I don't think you understand how a clutch works. If you clutch fully engages right off the line...you WILL SPIN, BOG or STALL. Which you agreed with. So now explain how you get a great, full traction launch on slicks with the clutch fully engaging instantly. Good luck with this one. And don't give me anymore of this "sweet spot" bullsh!t. I've launched on slicks plenty of times in different cars with different clutchs and I know how long it takes rpms to come down and then start climbing again after a hard launch.

You know that brings up a very interesting point.

First of all, cars that pull 1.0 60's do NOT have manual transmissions with conventional clutch setups so your comment holds literally no water at all.

Second, top fuel dragsters typically pull .8-1.0 60' times and they have a multi clutch plate system that slips the ENTIRE WAY DOWN THE 1/4 mile to keep the power right where they want it.

 

i meant a good clutch as in a healthy clutch, not some extreme high performance clutch.

yes i know about the multi clutch plate system, one clutch is engaged, the others are slipping, you let out the clutch more, it engages the next, and so on.

but you know what? this thread is bull**** now anyways, i don't know why we're wasting our time. you won't change what you think and i won't change what i think so what's the ****ing point now? so i'll just step down because i don't feel like typing ****ing essays anymore.

 

I'll give you one last chance to redeem yourself, because you so nicely avoiding answering my MAIN question, which was:

If you clutch fully engages right off the line...you WILL SPIN, BOG or STALL. Which you agreed with. So now explain how you get a great, full traction launch on slicks with the clutch fully engaging instantly.

Answer that and actually make some modicum of sense..and I'll shut up.

 

in raptorbh12's Z, the best launches come when he chirps, or a slight spin of the tires and the transition from spinning to traction are completely smooth. it's the only way to pull out of the hole that hard.

if you have a spinning problem, such as i in my lil 14 second fwd vw, riding the clutch and letting it slip cures that. but the clutch doesn't just slip for 30 ft. on a hard launch unless it sucks.

you are THE ONLY person to claim this. since this thread i have personally asked about 2 dozen people, mechanics, other racecar drivers, and car enthusiasts and no one has the same belief. you can't honestly think that all those people i've asked are wrong.

anyways, since i wrote another essay....god dammit...

 

Fastest daily drivin Corrado in the country supposedly resides in Cincy, Ive seen it... personally its a big $$ pit. It looks sweet with the custom twin turbo setup, he put down ~400 rwhp on a mustang dyno thats something like 480 dynojet. he ran a 13 @ 129 because of a little friend called traction... this is a street car and last i saw he had about 12K into the motor and was def. not stock bottom end... however the fastest corrado in the world as im aware of runs a 10.3 @ 145 and he doesnt live in the USA something like PR.

this is the corrado vs my buddy ryan in his supra...
1st run supra has car in his lane and wasnt trying...
supra not brake boosting & car in his lane vs. corrado
2nd run with the Supra actually trying and brake boosting...
Supra trying vs. Corrado

m not flaming on you car just relize that with that much money it takes alot to build a car that fast specially a VW...

as for the supra has about 10K in it ran 11.4 @ 135 on DR
and produces almost double the power... 675 pump 805 on race gas

 

I don't believe the 1.5 60' one bit. Until you video a 1.5 60' in your car with the slip, I call BS. Not enough power, gearing, and not the right suspension to do it.

 

i know the twin turbo corrado you're talking about, however it's definately not the fastest or most powerful daily driven one, i don't even know who owns that one, but it's definately not the fastest, i personally watched a 680whp supra get walked by a black turbo corrado this year at H20 in ocean city. however, it was a shops car, not a daily driver.

there's a guy around me who has one pushing a tad over 600whp at high boost and it's his daily driver. he pulled off an extremely low 11. totally forget the mph or 60 ft. though, i'll have to ask him next time i see him. he also only put about 8 grand into the setup and is still stock bottom end. the fastest vr6 in the world is on stock bottom end.

i'm not going for the fastest corrado. i figure if i turbo my car it'll just turn into problems, hence why i have an older style GTI that i'm putting a turbo VR into, still not going for the fastest unless i have a true sponser, it's just not worth it, but beating up on those damn hondas at MIR will be fun!

the 11 second car i'm talking about is an old vw beetle. just about 10 grand into it, 2.0L naturally aspirated. 230whp.

the key to building a fast watercooled VW though is put the engine you choose to use in the lightest model you can find, and turbo it. simple as that. which is what i'm currently doing.

btw...there is a time slip, it's been posted before but everyone claims a track error.

 

Forget the technical babble...whatever sounds good when you type it....right?

um...ok..I don't see how your 14 second street tired VW compares to a slicked up 350z...but you're the boss.

I asked 150 people and they all agreed with me.

If that's an essay, then you rode the short bus to school.


PS - YOU STILL DIDN'T ANSWER MY QUESTION.....

 

Close, it was a 12.98! here was the post a long time ago - Click Here

It was on MT ET Streets.

MI 35th never really specified what he considers street tires.

Although the ET street is DOT legal, it's generally accepted as a slick i guess. The new ET Street Radial is supposed to be very comparable in launching capabilities from what i've read, but I don't have the cash to go out and buy a set just to see if I can equal or best my time. Does anyone here have any experience with them? Do you guys still consider a drag radial a street tire? Just curious.

A 12 second na would be difficult on a plain old street tire, but I have seen member done12many2 cut sub 2.0 60ft's. With all bolt ons including cams i do think it is possible. Difficult, but possible. Not sure what his fastest time ended up being before he started spraying though.

I won't get into the whole 30/60ft/corrado launching argument...

Weather is getting cool down in Texas though so it's time to start hitting the drag strip again. Time to test out the APS plenum and new 5Zigen miracle exhaust!

Good luck to everyone racing this winter. Headed to Motorsport Ranch in Dallas this weekend for some road course driving but will be hitting the strip in the next week or two for sure. Hope to have some half decent results to share with you all.

 

15inch et street drag radials hook hard, but i went with these. I did a few passes last night with a 16psi in them, and pulled some 1.7s. i need more gear but im sure there is a ton left in them launching higher and harder. I have seen a few guys with the drag radials and they dont hook as hard from what i have seen with the 17" set up
