I think if I remember right, that specific course had a tight slalom into another tight 90* turn. It was killing a lot of the ap1 s2000's. I was having a hard time with the msm and it's 5400rpm blast of boost in 2nd. Trying to be light but firm on the gas, it tends to kick the rear end out if I push too much.

I still haven't really hit my stride with this car and autocross. I think once I get engine management and smooth out the powerband I'll have a much easier time. I hate hafting to drive it like a Honda, as in keeping the revs up high to make it move. I'm also still on stock suspension, once I lower it a little and get some sway bars with links I'll be able to tune it to how I like over just dealing with it. Next season should be much better.

 

By the way Oliver, You need to make a order with garage star and relocated that front license plate!

 

I've got a Thompson disappearing plate. It folds in at speed, fooled a few popos already bhehe.

 

I've seen those, don't they just flap around at high speed?

 

I doubt it'd flap, here's a pic at autox speeds, its pinned to the top. More speed should only pin it harder. Also, I think it divert a bit more air to the rad.

Bump an old thread

 

Well i have a Mazdaspeed miata. An inexpensive improvement you can do is to port the stock exhaust manifold.

There is about a 3mm lip on the exhaust manifold inlet port. I removed it on mine. Removing it made a substantial difference in the surface area of the port.







The next thing I did was made an electrolysis tank using a battery charger, water, super washing soda, & steel wire to remove the rust from the inside & outside of the manifold.

Then I ported the inside of it & polished the outside. I ported it with a rotary tool I bought at Northern Tools for about $50 that came with a flex shaft & all the stone, sanding, wire, & polishing bits I needed.







This improvement should flow much better spooling the turbo up sooner faster.
