This is looking awesome!

 

Almost forgot

 

Yip, certified badass. Nice work. As far as track car ND's go this one's on top for me.

 

Wow. I totally get why Mazda welded those hoops that way and I'm sure they'll hold up to a typical street roll-over, but damn. That really reinforces for me how inadequate stock roll-over protection is for any serious track use (pun intended).

 

Bit of delay on the engine. Moroso oil pan hit the oil pickup tube. Keegan had to make a 1/8" spacer, like an thick aluminum gasket. In the car, SPS tune loaded, fired up, system checks. Pan had a pinhole leak from a cold weld. Argh. Pan back out, sent to our welder for repair. Definitely a 5/7 :(

Hoping to get it all back together in time for MTTC round 1 at Buttonwillow in two weeks. Not likely, but we'll certainly try.

Regarding the power estimates, SPS was quoting PS. Once I got a few more data points to correlate to SAE whp on our dynojet, I come up with an estimate of about 195whp. That would be nice. We'll publish results of course.

 

Fitted.

These are 18x9 forged magnesium 6UL-MF test wheels with 225/35 A052's. If these were standard aluminum 6UL's, the weight would be about the same as 17's. 18" tire a bit lighter, 18" a bit heavier so a wash.

The 225/35/18 A052 tread measured at 232mm. The 245/40/17 RT660 measured at 242mm. Both on 9" +45. The mag is 14.4lbs. Interestingly, the AZ80 magnesium alloy has a much lower modulus than A356.2 casting or 6061 forging aluminum alloy. To match the bending (cornering) stiffness of our existing 17x9 6UL, we needed to build well past the JWL/VIA standard load of 530kg. We ended up at 650kg load rating as a good balance between weight, stiffness and fatigue life.

The flipside is that AZ80 has a better fatigue life per unit volume or mass. So we could build a VIA 530kg 18x9 mag at around 112 lbs. It just wouldn't handle as well as these beefy protos do. Crazy to think a 14lb 18" wheel is overbuilt.

So yeah, looks even better than I envisioned. If track testing confirms my hypothesis, we may offer this exact wheel in our standard tilt cast-flow formed aluminum 6UL at about 1/4 the price of the mags.

 

Hell yeah. 4 lug only for 5 lug availability too for the boat crew?

Y'all are gonna make me make bad choices. Lemme flat spot a couple more of my 17's then I might move to those 18's later in the season or next year.

Purdyyy

 

OH jeeze, those would look HAWT on my FD.

And LOVING how huevo looks, what an ideal seat time TT build. Killer.

 

I Love this car.

That is all.

 

From MTTC round 2 at Streets of Willow yesterday. Testing a bunch of prototype bits: 18's, brake ducts, suspension bits.

 

More pics from Streets of Willow at MTTC round #2 today.
17's look funny to me now.

 

Ooooof. 18's look like they belong on that car

 

 

Damn, great lap! Love how after Phil Hill you can see the car in front of you almost lose the rear end. Probably thinking "f*ck, f*ck, f*ck, f*ck, that Orange Miata is gaining on me." Lol.

Didn't realize you guys were revving that thing out to 7,800. Must be an absolute riot with the new cams haha.

 

It's fun. Not making much more power yet. Not sure if its the tune or header choice. Handling is super fun though. So agile but just stuck everywhere. Been making some changes, tweaks. Playing with some new valving on the shocks, diff tune, few other things.

 

Kick ***!

That Buttonwillow lap video jogged my memory of this clip from that day. Meant to post it back in January lol. First session out, myself and a few pony cars get stuck behind this 'Vette who was just sitting in the middle of the track, not letting anyone by, and then running away in the straights. I was still feeling my car out so I was complacent, but Emilio wasn't lol. All of a sudden, the orange ND is in my rearview elbowing through the pony cars, then he's past them, then he's past me

 

The w2w racer in me. I pass now.
