Was it a noticeable improvement over your last setup?

And I thought it used to pull hard.....HOLY ****. We were limited in the ability to go full throttle many places.....but when we did.....it pulled from .87 to .91g accelerating through 2nd gear. That's pretty cray cray in a Miata on asphalt and Autocross tires!!!

That thing lifts the nose on real man spring rates like Pats car does on stock springs.

What did you end up with for weight distribution after moving all the stuff towards the back?

I don't know yet. I haven't had it on the scales yet. Hope to have that done in the next week or so.

I liked your reactions to your car, especially the giggle after shifting into 3rd.

I was wondering about your S/C intake/throttle body setup. I saw that you have a 75mm TB, and that looks like a custom adapter from 75mm to the squoval whipple flange. Have you tried a larger/smaller TB back to back?

You changed your intake tubing length to the front of the car. Did you get an A/B test for the short vs. long? I assume you moved it for intake temperature reasons, but with the intercooler is that noticeable?

I was thinking of using a GT 500 throttle body and a custom "Plenum inlet" for my setup. In an academic sense (fluid dynamics and vacuum across an aperture) it should help a lot, and from a marketing perspective it has helped Kenne Bell. Any thoughts?

I have but not on this specific setup. Based on the amount of air the setup is flowing, the Throttle body doesn't pose a significant restriction.

I didn't do an A/B test. I actually did it for weight, "general neatness" under the hood, weight distribution from left to right and heat. The heat post IC is way down but that is due to the more efficient 1.6L supercharger vs the old 1.2L. The heat going into the blower will, however impact the life of the supercharger.

I was thinking of using a GT 500 throttle body and a custom "Plenum inlet" for my setup. In an academic sense (fluid dynamics and vacuum across an aperture) it should help a lot, and from a marketing perspective it has helped Kenne Bell. Any thoughts?

I consider that setup as well, but for my specific setup there wasn't enough room. You want the throttle body offset slightly to the side of the female rotor and as far away from the rotor pack as reasonably possible.(I have verified that with testing) At this point...the car is already making more power than a Miata chassis could effectively use in competition without active traction control...(and it's borderline making more than it can use WITH the traction control.) So I won't be making anymore power bumps until I can somehow make a Miata put power down like a Lotus.

It's a nationally competitive car.

Not too shabby... 1.5g sustained, looked like spikes past 2g!

Still incredible how the lotus cars are seconds faster than this in the same class.

Seconds faster? Where are you getting your information?

The Fastest Lotus has only ever been 3 10ths of a second faster than this car. And the gap was only that large once.

Most of the time the two cars are separated by THOUSANDTHS of a second.

Oh, i must have beenlooking at a few years ago.

Is there anywhere to look at your current standings? I think that would be fun to follow you.

I have. I have it working really well for Pro Solo. In Wilmington we cut a 1.801 and 1.803 60' times. On unpreped virgin concrete, A7's and the suspension set up to turn....that's pretty baller. It was the fastest front engine Rear drive car to 60' at the event.
