No ceiling in sight yet. We have been over 220 in experiments so far. I am very curious how many things from ND2 motor will bolt up to ND1 motor with supercharger. Perhaps the bigger throttle body? Perhaps the higher flowing head with bigger valves? All sort of untested potential.

Someone pointed out that you lost the tranny in your blue ND this weekend. Can you shed more light on the causal factors from your perspective?

Yep, at SCCA Practice event Saturday the trans 2nd gear went again. Typically about 12 runs on practice day, I got 5. Real shame, with each run I was setting and resetting Top Time of Day and it held all day if we don't count GoKarts. So, the car is working really well otherwise. Time for version 4, will start looking around the local yards and EBAY as time permits this week (also closing escrow on our new site for Good-Win Racing so that's about a million times more important at this moment).

I have lost two transmissions, same pattern both times. At the moment of failure full throttle and over 6500 rpms in 2nd gear, full load transition at the moment of failure AND steering input change from left to right on high grip tires (putting a lot of twist through everything).

I hear that ND2 trans internals not changed from ND1 version 4, but I also understand the case may be ribbed for less flex and those ribs continue into the lower part of the engine casting so entire unit of engine/trans will suffer less twist, which sounds like the right answer. This pic posted by FM's Keith at miata.net to point to some of the updates (like ND2 gets stronger engine case, upgraded connections to trans, and oil heat dump to coolant). My guess from pics is ND2 trans needs the ND2 engine, so upgrade to that ND2 trans will mean you put in the ND2 motor too. So, as soon as somebody has a line on first one to get crashed after release later this month, let me know!

Will the turbo you pulled out be available to be purchased in the bargain bin?

Are you breaking the case open and changing the internals with EMCO or OEM gears or are you changing the whole box?

What's the average time to remove a trans in the ND?

What other supporting mods were used to achieve 220? Is this to the wheels?

Over 220 was first experiment with E85 on otherwise stock Edelbrock install, done over a year ago. I never posted the chart and now I don't know where it is. But.....more on this very soon.

Interesting that you've chosen to go back to supercharged over turbo, even with the ND2 incoming - any insight as to why that choice was made?

That's what I get for drunk-posting...

UPDATE for AVO TURBO

Ross at AVO reports they found the purge valve leaks under boost a lot and can cause slight hesitation with on/off throttle and light throttle when the purge valve opens and shuts.

You will want to fit a one way valve as shown here.

[quote="Brian"]Ahh...proper seats!

Any recommendations on 'plug-n-play' seats? I need the 2" drop over the OEM seat, but this is still my daily and I'd love to find seats I can drop in for track days and HPDE events.

I like the sparco choice we have in the Blue ND, and I am about 2 inches lower. Call and talk to Ryan at our sales line for details.

Thanks. Struggling to find another ND on the local circuit to try some seats on for size.

Brian, any movement on the development of these "scoops"?

Brian wrote:Transmission cooling air scoop...for track users!

Tested with our turbo ND.

Coming to the site soon. Similar for diff also coming to site soon.
