Logical item to replace. It spins, it's heavy, and this is lighter; no brainer.

 

and a lot cheaper then the driveshaft shop one too

 

I read the thread title, and thought "wow, that HAD to be expensive AND a pain to install". Much to my surprise, it's quite sensible. I'd love to see if the dyno proves anything, but 15lbs of drivetrain weight is fantastic.

 

:+1:

 

Nice review :rock: most definitely I need to add this to my list. How about some pics?

 

I will post some up later today

 

i didnt even know they made one. I am interested to hear if you picked up any power.

Is there any type of warranty on the product?

They just started making them and I was fortunate enough to get the first one (guess it is because I have been bugging them so long to make it). I would be willing to bet that it makes power because the older Evos are picking up 3mph in the 1/4... so the gains are definitely there. As far as warranty, I am not sure what it is but, if this is ran on the Bad Bish, Ricer, and AWD's RS, and I believe the Bastard too, I don't think there is much to get warrantied (pretty solid part).

 

Too bad you didn't do some VDR pulls before and after.

Also did you notice a change in spool up?

Did you have to send in your front shaft to be balanced or you just got a core?

Spool seems the same.. when I slap some more e85 in the car I will do some logs to see if the spool changed (don't have logs on pump).

The whole shaft gets sent to you and you send yours back. The front section is different from the factory unit because it has a damper/chassis mount on the first section of AWD's shaft.

 

yes sir... limited down time is awesome

 

edited the first post with a side by side of the oem vs aluminum driveshaft... I might grab some installed pics later today if I get a chance

 

that is one nice piece.

 

Thanks for the pic..that bad boy looks awesome :rock:

 

i'm curios of how much power can it hold compare to steel. anyways, nice product regwrdless.

 

i usually could care less about parts, but very nice!

nm, i reread first post

 

I edited the first post with a picture of it installed... don't mind the dirt/carbon from my O2/dump downpipe...lol

 

Great writeup!! I want one now

 

Damn. I kinda want one now too.

 

I wonder if these is any disadvantage from going two-pieces to one-piece design, clearly there is a reason Mitsu put a joint in between.

 

I wondered that too.

 

Ha! I'm glad to see I'm not alone. I was wondering what the joint is for?

 

Flexibility maybe? I don't know, I'm curious too. Because ~20whp is really a good gain.
Beside, any downsides for aluminum vs. steel?

 

is it hard to install?

 

It's easy to install and the evo9 guys have run them for years.

 

This is on the list of things to do if you really want to separate your car from your average bolt-on car making good power. Reducing rotating mass is like 10x as effective as reducing unsprung mass.

Great mod, good pics!

 

I wish AWD was on here. For those of us that DD ours especially in winter I am just curious how it will hold up.

I know there are cars making 2x as much power but i wonder about longevity.

 

I would be more concerned of the vibration that 1 piece design may possibly create, you loss the connection joint which allows two seperate rotation so obviously the driveshaft was not designed to spin in a straight line. There must be a good reason for Mitsu to come out with this design,.

 

The whole assembly is balanced.... no vibrations with it. Mitsu may have a good reason, but there hasn't been any issues with AWD's shaft on the 8 and 9's... so I would say it has been proven to take abuse with no drawback.. or harm done to any other parts

 

The DS ones, despite their price, are top-notch. They are used on some seriously fast cars.....1000hp Mustangs and such.

Thanks for the review though. This is something that the Import scene seems to overlook.

 

looks like a real nice option to try out next year..to gain another few whp on the mr's would be real nice..anything to bring our whp back to normal! 750 for 20whp possibly = a good deal to me
