I'm interested in seeing some credible claims from sources who use correct scientific method and proper physics, if they're going to use any.

Scientific methods?

Who's going to give that info? Credible claims are only claims that are accepted by someone. It does not mean it will be credible to someone else. Everything is up to debate and any claim can be questioned. Sorry I couldn't find a correct scientific method and proper physics from a source. That is asking for a lot though. Good luck peeps!

BTW: I just came back from the Dyno shop, testing. Nevermind why I was there....not enough scientific data.

There was Turbo magazine that I was reading up on and low and behold...a modified Subaru was in there. Nothing new here but the owner of the Subaru had a custom driveshaft made for him since his stock unit was obliterated. The company's name was 'Front Range Driveline'.

I just got off the phone with 'Front Range Driveline'. Jim there stated that in order for a custom driveshaft to be made, he needs one measurment. He needs the measure of the stock driveshaft from end to end (Spline end of tranny to where the face bolts up or something other). I am no tranny expert. Jim does not make carbon fiber driveshafts. The Front Range Driveline shop makes aluminum ones though. The cost of the modification is $450. Jim stated that I can expect the aluminum unit to be 8-10lbs. This is a possible 25-27lbs savings in the drivetrain.....guesstimated.

So I ask, can anyone please provide Jim of Front Range Driveline with the proper measurement(s) of an SVX driveshaft? The companies contact and location is below. If someone that is knowledgable about the SVX driveline can please call them and let us know we need to let Jim know, so we can get this show on the road. I already took the first step. Thanks for any help on this.

BTW: TomsSVX....if you are reading this...perhaps when the XT6 is done and this becomes possible, I can do another car swap and get a driveshaft put in. Imagine that!

a one piece driveshaft was made for a 5mt not that long ago. The angles are too intense for a one piece. It will create vibrations that will not only be an annoyance but it could potentially destroy your transmission ie: blow apart the rear portion of the trans... So, I would recommend against ANY 1 piece Drive shaft. Thats why i always use customized SVX shafts with new universals

Kevin: You don't need to hurl that at me. I'm not looking for strife... I'm only offering why those two sources are questionable. You may wish to choose your links more carefully if your signature will carry, "The weight behind the statement made, directly depends on the evidence which has been presented." I'll leave it at that.

This is all in good natured fun. That is why I put the smiley faces in. I don't need to choose links more carefully. It is just info. Some will accept it, others will not. Everything is up to intepretation. I stop trying to prove stuff years ago and do modifications that I feel are worthwhile. Then report my findings. It's the curiousity and wanting to know that keeps me going. That's all!

No argument from me. I understand that the links that I provided are not suitable for you (and I am sure others as well). It suited me just fine. We agree to disagree. You are still cool with me though.

Let's try to have some fun with this shall we.

Reading tone in text is always a crapshoot, and it's a drag when confusion ensues. We're good.

...even if you don't agree with me. Hehehe!

YT, You ignorant slut!

j/k
I would only install a one piece driveshaft IF there were correct/corrected angles created to make it work first.

It's been about 2 years since I went there, but they did quote me at $200 for an aluminum drive shaft.

Wait, wait... we're messing up a perfectly good tech thread.

sorry.

I'll go to my room, now.

The scientific fact to be considered here is the relative distance of the reciprocating weight from the central point of rotation. In respect of a drive shaft, it is bugger all; pulley very little; flywheel significant.

There can be argument only in respect of cost/affect, strength/affect.

Driving a modified sports car, I once sat very close alongside a whipping and vibrating drive shaft, having to resist temptation and hold back on speed during a race. It was not a good feeling.

Tom is dead right in respect of his reasons why a one piece shaft is a bad, bad.

So, with all the information you have thus far, will you be going forth and trying out a custom driveshaft? Or will you not do it?

tubbstcg · #58 03-03-2008, 07:04 PM

I'm going forth into the night...if i can get the money together I think there will be a lot of gains with just improving the drive line and no one has seemed to go all out with it so i am going to try to be the first.

I'm hoping to have the wheels 5spd and drive shaft by around early summer late spring is where I'm shooting for

Looking forward to reading about your results. Thanks!
