yes it was... against an Evo IX and Evo X GSR. I think it was one of the edmunds inside line tests if the OP does a quick search he could probably pull it up. I assume because of the quick shifting time of the MR.

 

I thought I was gonna see some real, "back to back" lap time results.
I guess we will never know..

So in other words, upgrading this thing WILL be very difficult, bummer. One of the guys around me has an extra GTR tranny that he picked up when he bought his new tranny in case he blew his out when he is tracking it, kinda funny, theres an extra 35grand, lol. If the tranny is enclosed, how do you go about upgrading it? can it still be done, havent looked into it much, all i know is that it is a lot harder to mess with even for basic service.

 

I think the problem is most of the Xs you see going to the track you see are GSR. I do not think there is a MR doing super lap battles or putting down the horse power to be involved in any of the tuner mag comparisons. I would like to see some lap times of a tuned MR as well.

 

They used to say the same thing about turbochargers a few decades back.

 

I wasn't saying it can't be done, I was asking a question, I do not know how it's done. I picture enclosed as meaning that the tranny is kinda one unit, like it doesn't like to come apart. Which is why they replace the GTR tranny if anything goes wrong, since it's enclosed (not sure if thats because they don't trust people to take them apart or not). All in all, I was simply curious how you upgrade an enclosed unit, I know people tune the tranny controller for more power and do clutch packs, but honestly I don't know what clutch packs are, since like I said I haven't bothered to dive into learning about it since I wasn't interested in buying the product myself.

 

It's just a collection of castings and internal parts with lots of bolts, studs, nuts, & screws holding it together. I've not seen any service manuals on it, no available internal (or external) replacement parts or filters, etc - except for the oil it uses..

That just means it's new. There is nothing magic inside.

 

Obviously there is no magic, you didnt tell me anything i didn't already know...Anyone else perhaps, who knows anything about this tranny?

edit: actually forget it, this is getting way too off topic, back on topic for me.

 

I read a review where the guy who designed the evox specifically stated the mr would be faster around a track.

 

The Mitsubishi Process for dealing with a damaged/misbehaving SST tranny is to replace it with a new one and send the old one to Getrag. The SST Tranny is a single enclosed unit just like the GTR. Whether people can actually open up these single units using blowtorches etc and reinforce internals and put it back together for track use is a whole different discussion.

As for the original post about which one being quicker, stock for stock, the MR is quicker on the track for a novice to intermediate driver. For an expert driver, the GSR definitely holds better prospects due to lighter weight and continuous ability to slip the clutch as needed. As soon as you take "stock" out of the discussion, the GSR handily owns the MR even for moderate drivers. Both are great cars, and until the MR gets a decently strong transmission (aftermarket or stock), I do not think of it to be a fair comparison performance wise. But for Daily driving, the MR is a better fit due to its no hassle driveability.

Another way of looking at it is from the financial standpoint. The MR is considerably more expensive than the GSR. If the Difference is spent on a GSR, you'd have one hell of a better performer.

 

I still cannot understand how shifting a few tenths of a second quicker (by the ECU in an MR) equates to quicker lap times. Especially considering the softer suspension, the added weight, and less power. Just comparing the majority of MR and GSR dyno numbers shows us the power is significantly down in most MR's. This is backed up by 1/4 and 0-60 times a few tenths slower in the MR. Is the Getrag SST that good? Or are the majority of drivers that bad?

 

Significantly lower? not sure where you read it from. The SST tranny is basically a manual tranny electronically controlled by the ecu.

BM did a quarter mile run between the MR & GSR, the MR came faster. This is debatable as some magazine have different results. I assume a lot of them didn`t know how to use the launch control and wasn`t using the S-Sport mode.

Its not only the shifting that is quicker, rather the difference between 6 speed vs 5 speed. Closer gear ratio and more gears gives you quicker accelerations.

 

That must be an old article or something, because again, anything i have seen shows the MR loses at least 5% more power through it's drivetrain and also is heavier, so I do not believe that it will be quicker in the quarter mile, and I think 95% of people will agree, and if you look at non MR owners the number is probably higher (accounting for people defending their cars)

 

murlo: you seem to be "out to get" the MR, as in, anyone who says the GSR is faster you instantly jump on and say "YEAH! See, I told you so!", but when other people in this thread say they have seen reviews that say the MR is faster, you instantly call BS. Try to have a slightly more open mind, I see that you own a GSR and naturally you want to have your decision to purchase it over the MR reinforced with performance numbers.

Remember, for 95% of us on this board, who are nothing better than average drivers, that SST transmission will make a big difference on the track. You never miss a shift, the car blips the throttle for you on downshift, no heel-toe action needed, keeping both hands on the wheel for better control.

So why is it so difficult to believe? Just because of the minor weight penalty the MR suffers over the GSR? Remember, it's not only weight that is a big deal, it's where that weight is located, so just because the MR is heavier, doesn't automatically mean it's going to be slower.

You are correct that the GSR is a more modification friendly car, but there are buyers out there like myself, who won't be doing any more mods than a nice titanium exhaust system, intake, some coilovers, and sticky rubber. For us, the power holding of the MR's SST isn't a big deal. With the MR, I can have a relaxed, comfortable daily drive to work, but then (barring overheating issues) have some fun on the track every once in a while.

If you are going to be competitively racing your Evo, or building a dyno queen, or big horsepower drag car, than the GSR is the obvious choice. But if you aren't looking for any of that, the MR isn't a bad choice as a practical performance sedan.

As far as the magazine tests go, remember, different drivers will yield different results, so of course there are going to be variations. You say you have no proof or links to all these articles you have read that say the GSR is faster around the track, but a couple links, and a video reference (Best Motoring) have been posted showing that the MR is faster. Support your argument, people might tend to believe you more if you do.

 

Like I said, reliability aside, if TC-SST vs 5MT is the only variable on a stock vehicle on a track, TC-SST should win most of the cases due to gearing and shifting. In Japan you can have a GSR with TC-SST, and you can have the 'MR (GSR Premium)' with 5MT, so there is no suspension, rotor and weight discrepancy, and the SST is only a 44lbs penalty.

However, if I were to get an X, I'd choose either the RS again or the 5MT GSR for the obvious reasons. I'd probably wait for an XII though, when all the 'downsides' are fixed OEM wise and have many cookie cutter builds at a cheaper price.
