Did you do anything to the lower motor mount and transmission mount? Looking forward to anything you can share. How light were you able to get it before you started adding weight back?

Rick, the main trans mount had to be fabricated with a combination of the OEM trans mount and original rubber part, which sits on an aluminum tab that's part of the engine cradle.
The OEM (r) front engine mount remains intact but we added two solid ones to the trans case .One in the left front behind the starter, and one where the right axle exits the trans.
The transmission will sit firmly in place while the engine is out of it.
About 2930 with no ballast.

Bob, I'd love to see that , but you'd have to get in line...

Re: Dime Rocket- DNQ

Update here:
We got all the permanent weight for DF/S mounted up front and added a small weight box where we could easily fine tune the scale weight. Have to say , it didn't help much with the traction though. We're hoping it will be somewhat better at a national event prepared track, in the daytime
We haven't really done anything with the suspension yet.
I'm going to have to research the availability of an adjustable front strut or at least a stiffer one. Then maybe fool with the camber and toe in.
Still need to do something about the steering rack. We need to replace it with a manual one or maybe one tooth less on the pinion?

Anyway..Last night at Wild Horse:
90 to 100 degrees
4000 to 4600 da
28.5 baro

All runs between 1.09 and 1.14 under NHRA index for sea level tracks.

Re: Dime Rocket- DNQ

Somebody said a while back that some cars just have to be built.
Even if only a few of us care.
Thanks, bro

Is there any other kind?

Mark, BMR suspensions has suspension pieces for your car. Also, there is a company that sells a traction bar for controlling the front A-arms during acceleration and there are also aftermarket mount for the engine and transmission that replaces the gel filled OEM mounts. After looking at the BMR pieces, you might be able to replicate them.

You can use the KYB AGR adjustable front struts.

Re: Dime Rocket- DNQ

Thanks, Joe
I think we could use the struts.
The rest has already been addressed or lists only the 3800 (Buick) engine.

I'm thinking we need to change the top of strut swivel to something of a spherical bushing nature. That in itself ought to help with the hard steering problem.
Do you think we could find something close, or time to fab something there too?
You know anything about the rack/pinion tooth count deal?
