Tilton has always been regarded as the most lightweight, best clutch hands down for the Evo application. With 3 varieties, Hybrid Organic/Cerametallic, Twin cerametallic and true Carbon on Carbon there is a clutch for every application and budget.

Due to the lightweight of the tilton units, engine harmonics are more easily transferred to the spline and disc hubs (per Tilton). The disc rattle a bit at times and make some noise on decel. These are just part of owning a Tilton.

In rare cases the harmonics from the motor transferred to the disc splines can accelerate wear and damage the splines, requiring disc replacement sooner than expected. Some have experienced the P0300 (random misfire) code from this vibration.

Larger camshafts, stroker motors and slightly imbalanced motors are all candidates for accelerated spline wear as the increased vibration can be transferred to the input shaft on the transmisison.

ATI has released a SFI and NHRA approved super dampner that MAY help in all of these areas.



I am offering up a discounted ATI Super dampner to a TILTON owner that experiences any or all of these symtoms to see if this Super Dampner will reduce or eliminate some of all of the symptoms of excessive engine harmonics that can be transferred to the disc splines and input shaft. My best hope is that is solves this rare issue as well dampened the harmonics enough so that the P0300 code does not set of the CEL light.

If anyone is interested in a discounted ATI SFI approved harmonic dampner, please send me a PM for pricing.

This is not a profit source, this is an attempt to find the answer to dampening the harmonic of a tilton equipped Evo to cure potential issues and annoyances.

Thanks!

 

PM me with the price, hopefully it's less than the MSRP on the ATI website. I'm going ot be needing one for my new build.

 

$425 is our retail pricing.

If we can verify you puchased a Tilton from us, you will get cost pricing with the agreement that you will test the unit and provide feedback as to the results combined with the Tilton application so we can use this information as a benefit to other Evo owners and evolutionm.net's information archives.

 

man i would try this but i really don't feel like doing any labor hehe

 

Actually its just 4x 12mm bolts on the crank pulley and it comes off. The serpentine belt needs to be popped off also.

 

It's a five minute job! I'm interested to see how this works out myself...

 

don't I have to put the timing belt back on?

 

No Joker... The TBelt is on the inside of the cover, the crank pulley is on the outside of the cover. The are independent, but both turn on the crankshaft.

 

what...

"ATI has designed a 6.325” damper -- Part # 918250 -- for the Mistubishi Evolution VIII & IX 4G63 for high horsepower street & race use. This new design is a direct replacement for the stock OEM damper. The heart of this unit is the tried and true “damper within a damper” design that has put ATI ahead of the rest. The outer shell is machined to utilize the factory serpentine belt set-up and mounts to the factory crank via a custom hub which replaces the stock timing gear."

look at the pictures on the site

you have to remove the stock timing gear so the timing belt has to come off.

 

Well will you look at that, we are learning already...

So you add another 10 minutes to the install

 

no, if it is the same procedure as for the DSM's (which it sounds like it is), then this will add a couple of hours to the install as you'll need to remove the timing belt covers and essentially do a timing belt job to get the part installed.

 

I think you missed the joke dude.

 

I stand corrected

I thought is was a direct replacement for the OE crank pully

I'm sure it is a grade A peice, but that would make it a pain to install. I can swap my Perrin pully off and on quicker than most can make up their minds... and that was what I was thinking.

 

I run this combo on my car, ATI w/ tilton Carbon/Carbon, I would say it's the best combo of parts out there.

 

Doesn't look like you can run balance shafts with this either...
