How fast will the "Target 550" car go???

Bub 7 crashes at 300 Valerie OK

Video out now makes it look pretty bad......is the chassis a museum piece or can it be repaired?

nobody ever responded to my question about married or divorced drivetrain----

I went to the GG awards shindig yesterday and got my question answered  my suggestion would be to UNCOUPLE the  front and rear drive trains let them run separately   do not know if they are running a spool or not but if so go to a Torsen unit.

Is there a Torsen style diff that is strong enough? I have a Quaiffe That has been mostly reliable but I only put 300hp through it in a sports car. The thing that concerns me with a Torsen style differential is the handling change that will occur which is dramatic.  I think you will induce a spin much easier.  Am I wrong?

[Crackerman]

What about a slipper clutch type coupler? If the engines are close to hp and torque, something with as small as 200 ft/lbs ought to provide plenty of drive, but slip enough on shock loads? I don't know if it can recover the torque after slipping, but a spike ought to be eliminate.

I have run over 900 through a stock 7.5 unit out of a Camaro with 28 splines--I felt like it helped my old car go much straighter.

Sparky...I believe there is a "line shaft' that runs along side the engines and couples the whole affair together..I guess if they wanted to, They could run it with both engines and make it rear wheel drive only. Or front drive for that matter. JB

I use a Hewland Mk9 open diff with OK results against 342 HP and 195 ft lbs of torque. I have a Torsen diff planned to replace the open unit. The idea is to balance torque application just like your Quaiffe. Not sure why you think the Torsen would induce a spin??

JB  that is what I was told-- that is most likely would be a matter of just removing a belt coupler to set it up where they could run seperately

For those not familiar with the drive line.

   Tom, I just watched about a thousand pictures of Marlo's car build.  Thanks to your post I now have a blister on my finger. That car is as complex as my wife.

Thanks Tom   That  let's us cut to the chase

George,

Sorry about your finger, but hope you enjoyed the pictures.

Sparky,

Your welcome. Yes sometimes pictures are worth a thousand words, and there are more I just did not have time to find them all.
