now im just asking this out curiousity and i dont know much about transmissions, how hard would it be to convert a regular 5 speed pattern to a dog leg pattern on an fc? what kind of work would have to be done to make it happen?

not sure what you mean but changing shift patterns is out of the question unless you feel like fabricating a whole new transmission basically.

whats a dog leg pattern?

ViperDude152

You mean changing the gear ratios basically? To stay with-in the power band when shifting?

You mean german style like volkswagens? Anything is possible, that is, if you want it bad enough.

no that would be

Anything is possible with enough money - so yeah......you could do it

edit: oh I see why he asked about this, the website he linked says its on many "notable performance cars".........whats the matter, having trouble crossing the gate from 2nd to 3rd?hehehe

Ok, in that case... why are you asking? Or, why would someone want to?

"Dog leg pattern gearboxes are usually found on performance and racing automobiles. This is because in road racing it is rare to shift into first gear other than for the initial start or exiting a pit lane."

that'll be the first mod I do when I build a NASCAR FC

i see many of you do not know how transmissions are built, you cannot change the shift pattern period - unless you redesign the case and shift forks.

sure anything is possible with money but you would be much better off just replacing the transmission with the desired pattern and have a bellhousing adapter plate and input shaft made.

You want the least important gear to be the offset gear for an "intense" application. For most of us, that would be 5th gear, which is an overdrive. Most of us road warriors and autocrossers want an easy to use 1st gear. Road racers would want an easy to use 5th gear (for most tracks).

i saw one at 7stock last year, i believe it was at the mazdatrix booth?

cool_as_crap

when the hell would you want to hhit 5the gear on a track? how many road courses do you hit over 120mph?

I don't hit any. But, that's the logic.

I always saw the "dog leg" as more of a European thing. Considering just about every european car sold here with a Manual uses that shift pattern. While I've never seen a Japanese or US car with that pattern.

Ummm, at the track I've gone to you could hit 170+ in a high power TII with the right gearing. For refernece, a Ferrari 360 Challenge (roughly 420-420 FWHP) I rode in got close to 180 on this track.
I've seen very few recent cars that use this pattern, mainly because most that would have used it are now 6-speeds. The point of that pattern was to have 4 and 5 aligned to allow easier shifting on the high speeds of the Autobahn/Autostrada. With a 6 speed, 5th and 6th are now aligned using the normal shift pattern.
As Karak mentioned it would basically require an entirely new transmission to be swapped in to accomplish. You might as well just get a 6-speed.

iv always thought road courses wouldn't have that kind of straight distance.

im trying to find that tranny i saw at sevenstock, but doesnt look like its on their site

Secondmessiah

seems like the simplest way would be to just buy a dog leg gear box and put it in, because i dont think you could really change anything within the transmission to do that, unless you basically fabricated a new transmission
