Lots of progress today on the Twin Engine GTP !
Huge technical issues figured out.

There was a geometry issue with the suspension, toe in/out alignment.
The suspension had way too much travel because of the very stiff preload on the spring/shock.
I wanted something safe, reliable. We could have done the simple cable mod to limit the travel but a failure of the cable could be catastrophic on the big end at the speed I'll be crossing the traps.
So I figured out a way to limit the suspension travel in a safe way. The car should be ready to test this weekend. Maybe not track ready but ready for initial testing.
Here's the suspension fix. The Geometry issue with the toe in has been figured out and will be fixed tomorrow.

We wired most of the rear engine. Front engine is ready to go (not turbo yet but S/C small pulley).
Rear engine could fire as early as tomorrow night.

Tomorrow we fix the toe in issue, install rear axles and complete the reinforcement for the rear engine.
Pictures will be uploaded in a few minutes.

BTW the suspension limiter is equipped with a kevlar reinforced belt to have some give and it's bulletproof and will not shred. It's made to drive snowmobiles.
