5speed shifting challenge.

Anybody with a quarter horse and a 5speed want to have a 5speed shifting showdown. Corey and I were comparing shifting via quarter horse logs.

I guess we need standardization for the challenge. And I think 1-2 should be the most important shift so we can use that unless you guys want to share 2-3 shifts.

Anybody interested?
 
Put the back end of your car up on jackstands, run thru the first 3 gears as fast as you can bang the shifter, and then post the log.

Tightest peaks on the graph wins bragging rights...

Not quite. Real driving..
 
It does not really matter. Whatever your car is capable of.

The Quarterhorse has a counter/timer as you log, TB voltage should be logged so we know when you let off and went back on the throttle.

Posting the time and respective TB voltages, Rpm and MPH. The fist and last time of the tb in the closed range can be subtracted. To come up with your shifting time. Just an idea. You don't need to go out an do this over again if you have a log laying around from a track run. Its just a friendly challenge. Just need to implement standardization. Like the amount of data QH is logging off per second.

RPM matters. Anyone can shift fast at 3500rpm. Need to have a standard and the higher the better (within reason). I hear people complaining all the time that they can't shift @ 6000rpm so I think that would be a good #. ;):p
 
my car with brass blockers isnt' exactly fast shifting from 1-2 even with a ripper but I can still get it to chirp the tires. it makes me want to swap in a lentech aod.
 
I say 5000rpms and take the average the 1-2 and 2-3 shift on the same run up through the gears, that way even a stock SC can compete, and making it 2 shifts on the same run will help show who is consistently fast instead of someone just getting lucky with one good shift and going with that.

I've had a five speed Sc for two weeks and can shift at 5k no problem with a stock shifter I guess I have mad skills or a really good transmission .. :)
 
Jacob save the smack talk for the actual results. �� I think he said 6k but stock valve trains cannot that that abuse.. I don't want this to be a reason for broken blockers or valves. It be just good to see what the cream of the crop can do with a m5r2.

It really shifts descent for what it is no worse than a t45 with a stock shifter. Let me get my ripper installed and I will see what kinda numbers I can get :)
 
5k should be good for all cars stock or otherwise. What if you don't lift on a shift?;):cool: Mine really sucks right now cause its cold out.
 
Throttle lifts are deceiving and can't be used as a true judge of shift time. A simple spreadsheet could tell you when rpm/mph indicates the time spread between lockup in one gear vs. the next.

I will start another thead to only post results and order the from fastest to slowest.

I cant drive my car for a little bit but here are my results the RPM rule needs to be a little lenient I think no less of 5000rpms if you choose for more it only gets harder to shift anyways so you arent to get penalized.

Here are my results and the parameters to use when reviwing the data.

What do you agree should be the interval on my shift change logs?
 
I was hoping someone would jump in and say "I can make that spreadsheet!"

It's hard to tell from the data above because of how VB displays it. Someone should be able to just take a .csv datalog and copy/paste the data into a spreadsheet that calculates gear ratio based on rpm and mph. Then you could see exactly when 1st gear was valid, and when 2nd became valid., etc.

All that would be needed is ET,rpm,mph.
 
I think both 1-2 and 2-3 should be calculated. Both are critical and both are quite different to execute.
