Random drag racing question

Just curious. What is the fastest 1/4 mile in a manual transmission car with a traditional shift pattern that you know of?

my guess:

http://www.2jzpower.com/timeslips/toyota-supra-mkiv-sw-7-91-pass

but apparently the 7.91 pass was made in '09, so...?

Lenco plantary manuals have been around since the 70s...so, 6.455 in 2015.

Boosin' s Red Demon DSM has been running mid 7s on an H pattern gear box.  

In reply to Appleseed :

Lenco isn't really considered traditional shift pattern...

James Kempf's SpeedFactory Honda has been 7.585 / 206.16 mph...

That is mind boggling to me. 7 seconds while rowing gears is hugely impressive. It is ea$y to build a fast car, but to launch and shift something and do it that quickly... I can't wrap my head around it.

I’ve seen some 7.80’s out of c6 vettes.

In reply to Ranger50 :

in an 1/8,   that's two shifts.

In reply to GTXVette :

No full quarter.

Also a good way to make drag racing more interesting to watch:

- Require standard transmission with normal H style pattern

- No trans brakes, bump boxes etc.

- No wheelie bars

- No super super sticky tracks.

In reply to aircooled :

I've been down the track a few times, and that is exciting, but I generally find watching drag races pretty boring. Manual H pattern and no wheelie bars might make it more exciting for me. 

I just can't get that interested in auto cars with trans brakes and wheelie bars. Just wait for the light and hit the gas. (Yes I know it is more involved and technical, but I just can't make myself care)

Good luck with that. It isn’t fun to watch a smokeshow/pedalfest. Btdt. I still greatly dislike it, but Radial vs the world type class racing is awesome to watch. 315/60 radials with 4000hp running 3.6’s at 220... 

While I applaud the h pattern shifting, I can’t in good faith get behind needing $2k clutches either every other pass or third pass... This is why you see automatics when you get faster than 10.0’s... I can easily get a race weekend, 10 passes or so, accomplished for a pittance with an auto vs a manual. And that’s given you need a device to connect the engine to trans and the trans itself for both modes. Again, btdt.

This is the honda mentioned earlier in the thread, dang..

The boostin car, wow.

I dunno. I like $ caps. There are hundreds of ways to go fast on any type of equipment. I like to watch (and race) cars built for cheap. $ is the great equalizer.

Some of the best stick shift racing on the planet is the NMRA's Coyote Stock class. Factory sealed $6700 435hp 302ci NA crate engines on spec gas and spec tune. H-pattern shifters and diaphragm clutches. Automatics are legal, but i don't know of any in the class. Wheelies pretty much every pass, at 3100lbs, they are running 10.0 @ 129!

As far as I knew the rules changed and slipper clutches and non diaphragm clutches were allowed. You might get 4 passes before changing it out for another fusible link.

Yes, no autos, yet. Trick is finding a converter and trans that will tolerate 9k+ launch and  shift points with the given ruleset. C4’s quit about 8200... AOD’s... HAaHAHaha.... And no you can’t use the Joel’s on joy “Ford” powerglide....

In reply to weedburner :

Gen2 coyotes are $7200 and the tune is suckier. Lest not forget a Long G101a will cost you 6500$....

Coyote Stock has a 7800 rev limit as part of the spec tune, diaphragm PP's are required for manual trans cars.

A couple years ago, 3 or 4 passes was about the limit for what was then a state of the art clutch setup. Then a couple of the guys starting using my ClutchTamer and all that changed. When they tried to amend the rules to make the ClutchTamer illegal, there was a near mutiny as the guys did not want to go back to pulling the transmission every few runs. They ended up writing the ClutchTamer into the rules the next day.

I have a customer that runs in Factory Stock, which has pretty much the same clutch/converter/transmission rules as Coyote Stock. He ran pretty good last year with a state of the art C4, but this year he switched to a manual with an off-the-shelf SPEC diaphragm clutch controlled by a ClutchTamer. So far this year he has won 3 out of 4 events, and was runner-up in the only one that he didn't win. Last week he brought home $4700 from the rain delayed last couple rounds of the PA event on saturday, another $5000 for the Ohio race on sunday.

I don't know about that.  To me, much more interesting then the equivalent of watching two cannons fire.

The way I see it, the more difficult it is to do, the more chances of mistakes, and the more likely they are, the more interesting it is to watch.

Replacing a lot of clutches is an issue.  Of course, depending on what class you are talking about, they are effectively repairing the cars between runs anyway.

BTW - I am not really a drag racing fan in general, but I do appreciate the extreme automotive / engineering aspects of it.

I love small tire racing but could care less what transmission they run. My favorite manual trans car too watch is the black coyote swapped Capri that 1320 featured a few times. Running 8s with an h pattern driving it too the track is impressive.
