Love the simplicity!
Brake booster vacuum is provided by the cam driven 997GT3 vacuum pump. All the EVAP stuff is deleted, hence no #16 check valve. This is why all you have is the FPR vacuum/boost line at the top of the IPD plenum along with a boost sensor line and one for the diverter valves. Fuel tank is vented to the atmosphere same as on a Cup. All the emission stuff is gone.

Hopefully in about 45 days or so. I am having a driveway replaced at my house and it's going to take them 4-6 weeks to complete it. They are starting tear out tomorrow. Until that's done I can't get my trailer out. We should be at the dyno next week for tuning and then there are still a bunch of details to wrap up.

The only things i gathered are:
1. No A/C... ouch, but at least you're not in the southeast
2. The exhaust alone sums up your goal for Power, simplicity, and always going +1-up (1/4 wave pipes)

in all seriousness, you can easily create a tv show or fun book (Chronicles of a staged street car), with a plethora of information AND background as to WHY each thing is done, which speaks largely of your transparency... Bravo!

We are using coolshirt system but I'm really eyeing the Chillout system which circulates coolant thought a shirt eliminating the need to continually swap out ice water in the cooler. It's a pretty slick set up.

Very neat, and it only weighs 11lbs.

oh wow, that's interesting! Looks like a packaged unit, you just need to supply power and adapt drain/condensate line... passenger compartment, behind you I assume?
Does it create much heat, or does it act like a compressor on an EV (since it's all electric)?

Dirty but buttoned up ready for tuning.... Tons of room around the engine bay now. Looks stock for the most part...

Default Interested in headlights, can you send me a private message?

Thx.

With the said, I have a mint condition set of OEM Xenon light assemblies for sale now...

Not exact yet but should be right at 2750 with fuel, give or take... We are in the process of dyno tuning right now and then a few more details to tidy up before I put it on the scales for an alignment

That is solidly into bike power to weight ratios - that is going to be really fun to drive.
