For me the solid rear axle works great and has been very reliable and lighter than an IRS. We have learned a lot about IRSs over the last 8 years and they are better if you have the time and money to tune one.

I have driven a few traction control systems and (PTM) performance traction management systems and so far I've been faster without them. I can say that many less experienced people are faster with them. If you know the track, torque curve of the engine, gearing and have a very good tire model the PTM system is faster. But that means you need to tune it for each track and tire. I have been drivening big power cars with street rubber on them for many years and I’ve been able to calibrate my foot to get a good launch. But for 0-60 AWD is the way to go. Last year at OUSCI I had a near perfect launch for the Speed Stop deal hold about 0.8 G acceleration until 80 MPH on that dusty pad but the GTR still beat me with just WOTing it. I’m traction limited for now so adding any more power is not going to help me for the Speed Stop deal. And my braking is also nearly maxed out with the tires we can use for OUSCI.

In MI it is either snowing or above 90 degrees so I stay in the shop….

My buddy Ryan Kuhlenbeck is in town to help me get the wiring done on the ’67. He has helped me on the last 3 cars so we have the wiring for the LS9s sorted out. It is also much easier now that GM has a GMPP LSA harness to start from.

We have another version of the LS9 blower inlet that is opened up more than the one on the Red Devil. We hope to see some power gains out of that also.

Do you run the stock Tremec shifter we see there Mark or is that just for mockup?

Hey Mark, what clutch and brake pedal set-up are you using in this build? I know you've switched it up before in other cars. Thanks

I'm using the Tremec shifter. I'm using the stock '67 pedel set up with a 2002 F-car cluth slave with a DSE adapter bracket.

So how much longer?? Summers going to end!! Mark do you have to qualify for Optima or do you get in because of past winning?? If so where do you plan to qualify?

what clutch master cylinder do run in your cars?

The Optima guys already invited me. This car will be in the Optima battery booth at SEMA and in the OUSCI event. Now all I have to do is finish it....

Wiring Update
 

We are finishing up the wiring... Big job on a complicated build.

We keep a Excel spread sheet on all the wire, connectors and pinouts.

We will loom it all up when it is done.

Looking at all that wire makes my head smoke and my right eye get all twitchy...

A whole nother level of incredible engineering! Just amazing. :thumbsup:

What you can't just order up a new harness?? :faint: :faint: :faint:
