Hi guys 

I'm in the process of getting my tail shaft modified to suit a big box (rb25) going into a r32 and the shop has emailed me saying is going to be cheaper to make a single piece as the car is track use only is there any cons to going single piece?

Cheers

Go 2 piece, its worth the $$$$.

I have a 1 piece in my rb25 sil80 and its always had a weird frequency issue. I have a new 2 piece in the race car I am driving thursday so will update then.
Some events require a tailshaft loop for 1 piece so easy to go 2 piece, one less hassle.

Also only need to do front half with a new yoke.

@34GeeTeeTee any thoughts about single piece motorsport tailshafts :rofl:

:rofl:

Yeah, Go 1pc they said... It'll be fun they said!

2pc is the only way to go in our cars, doesn't matter what the shop says... It is an expensive exercise to test their theory! Ask me how I know :P

I have no issues with my single piece driveshaft but I did muck about with my motor mounts to get a perfect +2, -2 degree's between trans and diff. Mind you, as I'm breaking my motor in amongst other things, I have not got over 120kmh.

Mine had no real issues for the first 4 rounds as most days were 170kmh max! Once I got over that and into the mid 200s it got scary! My engine and gearbox mounts are hardened rubber and the diff is solid mounted to a solid mounted subframe so I doubt angles or movement had anything to do with it. Will know for sure in a few weeks when I head back to test at SMSP before Round 6.

Only problem I have with the 1 piece is changing diffs, you have little to no room to side the driveshaft back and forth. Apart from that it’s a 3.5inch one and it’s fine, track has seen north of 220 with ease, car already makes lots of noises but driving it around town is no problem. Oh and dropping the gearbox is a pain but it’s the price you pay

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
