LMM / allison 6 speed in 30' sonic boat

[duramaxnate]

I had the pleasure of tuning this thing.

It has an lmm with a s475 over a Garrett 4094, built trans and a surface drive.

Spent the day yesterday dialing it in and making sure that we have a good idea how this combo performs. I had a lot of fun riding in this.

Here is a video of a run we did.

We have something fine tuning to do but we pretty much have a baseline for it.

We just need more real estate..

That engine sounds right at home from I could hear in the video at 63 mph(?) what RPM was it at.?

Neat. Sounds goods. Those sonics boats are quick, I redid a 46' with tripple 575's with tripple whipples, it was fun to say the least...

This was around 43 around 2600 rpm.

I will change my quote when I get on my computer..
