Misinformation!

 

The guy who posted before you is right. The 6 speed gear box is weak sauce and if you track the car, then you will break it. The high gears are small and thin and cannot take the heat and track load. For daily driving the 6 speed is fine, but for the track it is a POS.

I have read about at least 4 people who have broen their 6 speed tracking the MR.

The sad thing is that the Evo never needed the 6 speed. It was a marketing gimmick to compete with the 6 speed STI.

 

All I have to say, is. The Rally cars all have five speeds. The REAL race cars in WRC. So, I know that says a lot.

 

Ok.

But don't you agree that the 4th gear is too long?
(5-Gear-Version..)

 

That aren't even close to the production 5spds. That has no relevance to this discussion. Let me know when a production car comes with a sequential dogbox or whatever WRC is using these days.

 

Unfortunately there isn't much option for the Evo9, in the states...the effective gearing is pretty similar between the 5-speed & 6-speed; the 6-speed just has an additional ratio between 4th and "overdrive" (6th). Worse outside the US though I guess as you have no option at all

It would be nice if the Evo8 ratios were still available in the new cars without swapping transmissions.

 

You mean Mitsu isn't putting straight cut gears in their lancers? Dammit! I wanna sound like I'm in reverse 24/7.

 

Uh, no. The gear being longer permits me to run the 1/4 mile without going into fifth, like an MR. Thus lowers my E/T. Trust me, the MR is a gimmick. Also, if you look at the japanese site, they still sell 5 speeds on the GT and RS models. The GSR, which has the AYC, only has the extra gear because of the AYC, from what I've read. It allows the car to distribute the power better, somehow, with the AYC.

 

You sure about that? WRC requires the stock engines to be used, with only certain modifications, i.e. weight reduction, some intake and exhaust mods, but nothing really internal. That's why you must meet holomogation standards to BE in the WRC. Mitsubishi has to produce a certain number of Evo's to be allowed to compete. Secondly, it is the same gear box. The engines must be 2.0L also. Which is why the WRX STi in Japan has a 2.0L and the US version is the 2.5, which was made to sell to V8 guys who are interested in how high the horsepower is. Subaru felt the STi would out sell the Evo in the states by having a 2.5L, which has more stock power. Finally, this thereby proves that you must use the stock engine and stock internals in WRC, being that Subaru has to produce so many 2.0Ls in Japan, in their STi's. The Five Speed in our cars has been used with every Evo since the Evo 1. Its been developed, enhanced, and made to be a part of the Evo. This Six-Speed is a new gearbox that debuted with the Evo 8 MR. So, I'd OBVIOUSLY trust the Five Speed more, being that it's been around longer.

 

Misinformation.

1. The Evo WRC 04 gearbox is made by ricardo, is a dogbox and is a 5spd

2. The Evo WRC 02 used a 6 speed sequential (Xtrac or INVECS)

3. The Evo WRC05 is using automatic clutch and paddle shifters like most of the other WRC cars

4. The WRC motors on the Subaru and the Mitsubishi is not just stock with bolt ons. if you have seen photos of them, you would not say this. Yes, they have to be a certain displacement and are capped with a restrictor but thats about it. They have full standalones, different turbo chargers, different intercooler and routing, cooling, etc.

Now, Group N has a bit more rules but its still not using the stock gearbox:

that's funny since they shortened the 5-speed's gear's in the 9's and they are almost as short as the 6-speed. short gears make a much bigger difference in traction in high hp turbo vehicles or FF turbo cars. most evo's with 300-370whp don't have too many traction issues due to the fantastic AWD setup. if you mean having to go to 5th in the 1/4, add cams, headstuds, raise rev-limit, stir and enjoy!

 

don't evo's in europe and japan all come with the 6-speed, not just MR? i thought it wasn't a choice overseas? anyone confirm?

 

Not the traction issue.The point is the turbo can't make power at that rpm which is hurting also

 

in europe all evo9 have a 6-speed-gearbox.

 

i'm having trouble understanding. i hit full boost at the same rpm as a 5-speed and redline at the same rpm/boost as a 5-speed. doing a 4th gear pull on a dyno with same mods the 6-speed power curve will look almost identical to a 5-speed equally modded. please clarify.
