Well a few months ago I purchased a Ingalls Stiffy(engine torque damper).

Sold as fitting 03 to 05 350z. Turns out they don't fit the Rev Up motor. Speaking to Todd from Ingalls, they have been searching for someone with a Rev Up to use as a test vehicle. I think the deal is a free stiffy in exchange.

The sooner they get one in to test the sooner I can get the right brackets for mine. Here is the link http://www.ingallseng.com/parts/ETD/93035.htm

 

There must be someone in CO. near InGalls interested in letting them use your car as a test car? If someone steps up, please let me know the out come.

 

Just sent off an email volunteering mine...

 

Great, can you keep me up to date on your progress?

 

Robert_K has this on his car. said he could feel no difference. i wouldn't waste your money.

 

He must have it adjusted to soft. Check on this site and others and you will read differently. Smoother shifting, quicker launches were the most common.

My main reason for getting was that I have the Nismo exhaust and have read that they can break hi-flow cats. The less flex of the engine the less stress on the cats.

 

When I had mine it was set by InGalls. I was the orginal Z33 (VQ35DE) R&D car. Quality part for sure but usefull I don't think.

gr8scott: GL with them. Suggestion; Stay with your car! I dropped mine off and came back to donuts in thier parking lot. I'm not 100% it was from "my" car but I take it as a lesson learned about leaving my car alone.
