DEVO Tuning driveshaft.
evodan, last time Trent drove the car was at the racetrack 3 weeks ago. We had about 40 psi then and today the boost was only at 33-34. No, he could not feel a difference. When I tested brake rotors that were lighter the car gained around 5 whp if I remember correctly. This is 11 pounds lighter, some of that is from the carrier bearing. It is also rotating weight but I think will have a larger effect on WHP than the rotors because of removing the extra u-joint and change in direction of the shaft. I can tell you from past experience changing a long driveshaft on a F650 we built to a shorter shaft had a huge effect on HP, extreme case of long and shorter though.
nightwalker, what you suggested is always the case. Then you have to look at what you are saving and what the effects of your actions are. Here you have a company, DEVO Tuning, who took the time to have this made, offers it at a very low cost compared to anything else out there and supports this community. Yes, you can have it built but who is going to help you in the future with your EVO or other new products, "Billy Bob's driveshaft shop" or DEVO Tuning? I could have had this built after seeing it, but I respected DEVO and got it from them.
Support the good EVO shops, if you don't they won't be able to survive, especially in this economy. If that happens you will be buying all your parts from "Sum-ting-wong EVO Parts" on Ebay."

Well put David, well put.
Adam is trying to get as many together at a time to help make the production go more quickly. Seriously dont waste your time with some other shop when someone has put the time and effort into coming up with this idea already. Ive had this for two years now on my car and i routinely goto the road tracks around the midwest. I drive the car there race all weekend and come home with no issues. Dave is right and this should have been factory.
I'd be willing to place money Mitsu did it because they had a drive shaft that was already tooled for they could simply adapt instead of spending millions retooling their factory to pump out drive shafts for 1 production model...
The cost of re-tooling to build a two piece shaft would be offset by the savings in the u-joints, carrier bearings and extra piece welded to the underside of the car quite quickly. I do not have an answer why they did a 3 piece shaft. Sometimes things are for noise and vibration when dealing with a mass produced car, that could be the case with this.
your joking me right??? lighter rotational parts make a difference. do a little searching and you will see a few cases of this being proven. im not gonna go into this again.
edit. its not about just droping static weight. witch is where your milk jug theory was headed
