I'm interested in more info. Is he running ITB's? What compression?

 

No he's not running ITB's, and no he won't tell you anything else. It was plainly secret in the 25hr thunderhill thread. And although a little disappointing, he has his reasons I'm sure.

 

Anybody know what the most powerful N/A VVT engine is? If 170 is doable w/ bolt ons then I'd imagine 200 would be doable w/ IRTB's, full exhaust, and a good 93 octane tune.

I remember this too. I asked him if he knew where the thread was but he didn't know. Something makes me think it was in the ramble on thread, too bad.

 

I highly doubt Emillio left any power on the table. Maybe he sacrificed a few for reliability in a 25 hour race, but not 30.

 

I was assuming that he was not allowed to make whatever modification he wanted, and the IRTB would net a little power, not 30, but some.

 

Spending money on an NA Miata?

Bone stock
NA6 90 whp
NA8 102whp
NB1 112whp
NB2 108whp

Give or take, that's what they make. Healthy junkyard NB1 and NB2 motors with I/H/E and ECU will make 140-145whp without too much trouble. A bit more compression, square top manifold and minor head work can bring that to 160whp. Lots of compression and mild cam up to about 175whp. Big cams, IRTB's, E85, 200whp+

Race reliable 25% power increase with bolt-ons is often enough for those not looking for only straight line thrills or drag racing.

 

Yeah... The Maruha/GarageOneHundred car.

If you're not talking an all out race car, Chikara Motorsports has cracked 190whp on a dynapack with a 1.9LVVT motor with all the fixin's.

 

Well I stand corrected. I'm guessing crusher "only" had 170 (right?) due to rule and reliability restrictions.
