So with those specs your driveshaft speed would be 8,733 RPM @ 200km/h or 125mph.
Critical speed calculations don't match up with that but don't know the full specs on the driveshaft yet.
Calculated:
13,923 RPM Critical Speed
6,961 RPM 1/2 Critical Speed
Using:
40" length
.125 wall thickness...
Well put.
If the vehicle was mainly stored in a milder climate such as Chicago for a majority of its live vs. Arizona that could change things significantly.
It might be in great shape, but does the price justify it?
Depends on what people value.
Just the interior color alone is enough for me...
What are your tire sizes to determine wheel diameter?
Also what vehicle speed do you typically notice the vibration?
This could help pinpoint where its coming from.
Easier to back calculate driveshaft RPM from wheel diameter and final drive ratio.
Carbon fiber will pretty much negate any...
That's an interesting piece of information.
If it didn't spend a majority of its time in the southern heat, components might be in better condition than I initially expected.
Somebody post up what this thing sells for, in case I miss it.
Will be interesting to see what the market values...
Yep.
Would rather get one that was well maintained.
This one while appears to be in great shape visually will end up needing lots of work.
All rubber components are likely degraded and or dry rotted.
Tires
Subframe bushings
Suspension bushings
Ball joint control arm boots
Steering rack bellows...
Haha.
Wow.
Has the hideous red interior too!
"THE ONLY THINGS THAT HAVE BEEN CHANGED ON THE CAR ARE THE BATTERY AND THE THREE-PIECE BBS WHEELS WHICH WERE ADDED WHEN CAR WAS NEW"
Based on the color of the fluid in the brake reservoir I wonder if any fluids were ever changed.
Could be a nice...
Have you used the calculator I created yet to see where your 1/2 critical speed is with your driveshaft / final drive ratio / transmission ratios / wheel size ect...?
I tried estimating with the limited amount of information you gave but its probably not accurate.
I would guess you are...
Wouldn't make an impact.
You are going to need a new company to oversee the entire US distribution of Tokico products.
Mport says they are not that company any more, before that it was Motovicity.
I was told that Hitachi put this product on back-order indefinitely.
So you would likely need...
Yeah there is no chance for these Tokico shocks.
I have exhausted all avenues for finding any more of these parts.
Only needed 1 more front shock!
So unless someone has a set on hand NIB, they are gone.
We lost our US distributor for Tokico and Hitachi paid their fine for price fixing - 12...
Yeah the feature list for these EFR turbos is very appealing.
They really allow you to simplify and downsize the extra ancillary components usually required to control a turbo.
Great for cleaning up the bay and packaging.
The internal wastegate sounds very capable on these turbos as well...
Agreed.
When you think about what it took to make it and what it would take to duplicate it again.
Yes it is sad to use it sometimes.
Even more so in the MKIV world, where TRD parts are going for thousands of dollars.
Its nuts.
Yes, you could be hitting the 1st or 2nd harmonic.
Have you used the calculator to check this?
Also what are your driveshaft dimensions?
1 piece / 2 piece ?
Aluminum? Steel?
Diameter? Length?
Spoke with B.W. on the topic for the 7M 3.0L Engine.
For a power goal in the 500RWHP+ range they recommend:
- B2 EFR Frame
- Minimum of 7670
- Twin Scroll .92 A/R
B1 Frame is too small for the 3.0L.
Need to move to the B2 frame, otherwise on the top end the exhaust flow for this...
I have started collecting parts to get a new turbo setup in the mid to far future.
Given up on CT-26 upgrades or the strange Mamba setups that may or may not have longevity issues.
There are much better options available now. (Actually the B.W. EFR series has been around for some time, but I...
