Amazing! Impressive results. What a way to close out the season after putting so much work into the car.

Thanks! And yes, you do indeed. Having trouble narrowing that down. Have played with different MC sizes and rod lengths. Going to need to drop the subframe/engine/trans here again and take some precise measurements of TOB range of motion relative to clutch fingers, etc. to figure out what's going on.

Haven't scaled it at this point but based on the last time I did and some fairly detailed notes I keep on anything that goes on or comes off the car, I'm estimating 2275 with me in it. There's more weight to be cut for 2018.

I just watched the video - torque for days! I love how infrequently you need to shift.

CONGRATULATIONS!!! What a pay off for all that hard work! Well Bloody done.

Our first Superlap meeting of the season is in 2 weeks, competitors look tough this season. A 20b powered FD and a Caymen Gt4 amongst others.....The Rwd drive win seems a touch out of reach this year for us but we'll see.

Great news for you, imagine the potential laptimes in your car!!

Official results are up on the GTA site. I've just noticed this car beat the entire Limited AWD class as well, GTRs and all. Quite pleased with that.

Amazing!

I love that the guy who drives for "hoonigan" was 5 seconds behind in last.

Also surprising that all 3 unlimited FWD cars bested the whole field of unlimited RWD.

Yeah not sure why that M3 was driving around in reverse....
The Unlimited FWD class has had a recent surge forward in prep level among those three - spurred by their competitiveness with each other. Those cars are very well prepped and running more power than nearly any of the URWD cars that ran this year.

He doesn't "drive for" hoonigan. He is an employee there that enjoys track days. Still a slow time, but he's not a paid hoonigan driver or something.

Showing up and putting the business you work for as your title sponsor effectively makes you "driving for" them. But yeah, that is an Enthusiast class car from the looks of the prep, probably only ran in Limited due to wanting to run certain tires.

Sure. But Hoonigan also employs professional drivers, of which he is not one. He gets paid to do social media things at hoonigan, and drives for fun.

Car is an M3 with a supercharger on like BC coils or something. Not really in the right class.

Agreed. My point is just that if you put the business name on the entry, now you are representing them.

Fair enough.

Car looked awesome and fast, anything you are going to change? Or stuff you would do differently? Other than more aero and things.

Yes.

Priority one is refining things from here. I think we've established this is a great recipe now I need to dial in all the details. My observation is that this is really the major difference between a traditional time attack approach - where the car is ran infrequently and so even though it's fast the team is never really extracting its full potential - compared, say, to a higher level road race approach which is ran almost every weekend and every detail gets optimized and the car is doing more than you'd even believe if you looked at its specs on paper. That takes seasons to develop though, so there's some work ahead of me!

Got wind that Speedventures is hosting a weekend out at Chuckwalla Valley Raceway this coming weekend. after the success - and also all the stress and long hours - of SLB, I figure it would be nice to finish the season off with a fun no-pressure event. Could even get some early 2018 testing in, plus CVR is just a great Miata track.

The plan is mostly to just roll the car out there in the same trim as it ran at Buttonwillow, but first I did a post-race inspection. Superlap wasn't easy on the car, there's several things that took some damage and need repairs, and a couple of those things need addressing before going to CVR.

First, the front upper ball joints decided to try to remove themselves from the upper arms. Going back through notes I realized V8R recommends tack welding these in to the arms to avoid this. Clearly, that would have been a good idea.



Took this as a sign it was time to improve the front upper arms. Switching to the V8R X-Lite front uppers. Spherical bearings throughout and track-side quick camber adjustment via shims. Also, 0.95 lbs lighter than the arms they are replacing (each).





Second, the mounting tab on each of the shorty mufflers broke. The safety wire was the track-side fix at SLB. These were made with really thin material to cut weight, clearly just a little too thin. Remaking them with thicker material today:

Ryan, consider using something that allows some movement on those exhaust tabs. Bolted with a spring etc. They need room to grow and move a bit IMHO.

Look forward to future endeavors. You've got one hell of a machine there!

Flying out to PRI tomorrow morning. You can bet I'll be doing some research for Hyper while I'm there.

The last two weeks or so have been refreshing, have been going home after work instead of spending long nights in the shop. It won't last though, dreaming up lots of improvements to get started on soon.
