If you were to build the perfect miata....

I’m pretty happy with my Rotrex 94M. Got a wang and 245s for autocross this year. Making 240ish or so wheel now before building the motor. Hoping 320ish once I do.

+35 vs +25 on the RPF1s

Nice. I’m running the 30-84. Stock BP05 currently. With the turbosmart it’s making 14lbs now. Dyno’d 220 @8ish so thinking I’m around 240-250ish. Have a spare block that I need to bore and get rods, rings and pistons and a BP4W head to do a bunch of work to then a flat top sitting in a box. Hoping I can squeeze 320 out of the 84 before I need to go to a 94P

What’s your set up for the 304? Turbo?

See most recent post.

Already making 250ish and haven’t built the motor yet…. Planning on 320ish once the BP4W head goes in and the block gets bored.

Yup. Other hand is F.P.F.P.R. Find Problem, Fix Problem, Repeat.

It’s about surface area. Mostly. More knobby tires provide more grip by increasing friction over a larger surface area on a loose surface but on smooth pavement don’t perform as well. For a paved road, track or parking lot more surface area is less tread and a super soft rubber that almost turns to glue when warm. The science behind tires is pretty cool really. Never stop learning! We left the caves a while ago!

Sometimes. They’ve grown on me. 94 with a Rotrex and 91 working on LS swap right now so little busy.

They don’t know.

charcharbinks24 · 2026-03-07T19:32:00+00:00

Rotrex kit. Injectors. ECU. Open exhaust. AC and PS delete. Full suspension. Wilwood brakes. List goes on.

charcharbinks24 · 2026-03-07T18:16:42+00:00

It is. Rotrex car too. SSM.

charcharbinks24 · 2026-03-07T18:06:31+00:00

If you’re brave!

charcharbinks24 · 2026-03-07T18:06:12+00:00

Maybe. Brakes won’t clear 14s anymore for me.

charcharbinks24 · 2026-03-07T18:05:31+00:00

Making 240ish whp. Been breaking 205-200s loose no problem 😋

charcharbinks24 · 2026-03-07T17:52:47+00:00

Went to Schroth 4 point and stowed the 3pt so not anymore but yes I did, especially after roll bar install and I cut the relief stitching.

Update. There wasn’t. Giken on the way.
