Should be a nice combo!
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Just got off the phone with Modern Driveline. They can do a brand new T5z with a 2.95 first and a .73 5th for a little under $2300. That sounds like it's going to do the trick.
Well, I could have saved myself a lot of time, but I guess that's how you learn. Everything looked great with the transmission, so I read up on people adding some Luca Oil Stabilizer to the ATF in their T5s. I put about .5 quart in, and I'd say the noise has been cut down by 50%. It's completely liveable.
My buddy?s cobra trans sounds like it has no fluid in it has sense it was new...great build
looks great! I noticed a very large difference at 70 mph with my 122 when running an air dam. Without it, it was very loose, and you could feel the front end lift if you pointed it into a headwind. With the dam on, its worlds different, still gets light, but no where near the extent.
Good to hear. I was talking to a 60's Mustang driver who had the same experience when he put a pretty small lip on his car. It would be nice if it felt more planted.
I think Fredrik Hilman has a mold for the 140 airdams, might hit him up.
When I put the airdam on mine (one of the IPD ones from way back), it made a BIG difference in stability from about 50mph on up. It still gets a little light at speed like everything, but the difference between stock and with the airdam, it's WAY more stable, definitely pulls down a good bit now.
I forget if you tried a yoke with the balancer, but that might help even with the new trans.
Is Fredrik on Tbricks? I've never met him. I heard back from that Swedish company. It would cost $260 to get that airdam shipped to California. Not outrageous, but enough that I'll want to think about it for a bit. I definitely need to get something on there before the next big roadtrip.
As for the damped slip yoke... I wanted to try something like that but the driveline guy at the shop said he hates dampers and didn't stock anything. I should have insisted, but I was on a tight time line. My vibrations seem more RPM/ger selection based than wheel speed based. I took that to mean it was happening within the gear box and not the driveline. Though I guess the damped yoke would effectively damp gear lash too. I'll look into that.
I hate to say this but you are probably on point with it being in the gear box. Did you set the input shaft preload properly?
So...my 140 has an RPM specific vibration as well, not vehicle speed dependent. Input is preloaded at .006", counter at the same. Swapping in the balancer yoke changed the dynamics of the vibration a LOT, reduced the severity and rpm range of it by a pretty good margin. Makes no sense, but it helped. On decel it would start at any rpm over 3k, any gear, and shut off hard at 2700rpm. With the balancer it is gone if you decel over 4k, still there from 4k down to 2700 but about half the severity.
Yeah, Fredrik is on here from time to time and on the TB FB group (Fredrik Hillman).
Honestly I'm going to just buy a new T5z with better ratios and call it good.
You know how 'long' 5th is in those, right?
