STL engine builds?

[mossaidis]

Mickey wondering if STL is some deep seeded urge and "secret" way to get other manufacturers other than Honda and *maybe* Miata to produce small displacement, higher hp, freer breathering engines in the US. hmmm...

Also, remember that rods, vales, valve springs, flywheel/clutch are free too.

Riddle this to me regarding the BP Miata;

A SM can make 131 WHP through 41mm restrictor.

I know of ITS Miatas that have made north of 160 WHP with stock cams and .5 increase in compression ratio.

How can a major increase in cam shaft, compression, lighter flywheel, lighter rotating assembly, stand alone engine management, not make atleast 180 WHP?

Chris - you are contributing to the theoretical noise. We don't know as much as we think we know, starting with the power and legality of those ITS Miatae. If you play the game, everyone else will be allowed to play the game, and you suggested above that we should go racing and complain later.

Damn you for making sense!

Because nobody has done one. A well known builder up here had ideas on what an ITA motor COULD make given what he saw from unknown engines and SM 'data'. Guess what? SAME NUMBERS as I make and have been quoting. These things are just not linear. The ISC cars make ~ 155whp on a 'regular dyno', not the optimistic one they use to tune. I am not sure what is possible because I have never done one but I can tell you that traditional upgrades don't take effect like some other motors. Stand alone engine management is the big HP bump in these motors and it's included in the IT number already. Build one. I can't wait to see the results. If it makes the number, you have a second legit choice.

Run the math, in order for a Miata to be equal to a 185whp Honda on paper, what will it have to make?

Lots of truthiness going around today...

....I have never done one but I can tell you ...

Damn. And you had me at the first sentence...

[Andy Bettencourt]

The whole point is that even IF the Miata proves to make the power (those of us with actual IT build experience know those limitations) it will still only be one of two choices.

OPEN UP THE CLASS to the 13B and older chassis with modern motors. This will at least get people interested in exploring options. People looking from the outside in see that they need 185whp in a FWD car and at least that out of their RWD to be close on paper.

Yikes.

I agree but 40-50 posts ago it was explained this is a "< 2L Tuner class". It is an arena for <2L FWD cars to race and compete.

Funny, 13B is 1300cc's.
