I do have to admit, it's how I feel every time I go to his website.

Default 2012 T25 dyno

Now that Crusher has been sold and we're not likely to ever contest PTC or E1 in a Miata again, I thought I would share some info. This was the winning config we took to T25 in 2012 for E1.
We were allowed 170whp so that's what we tuned to. This was on Sunoco 100 unleaded.

85.5mm pistons, 10.5:1, stage 2 Integral cams, BP6D head. Square top, RB header and 2.5" exhaust. Same porting and chamber work as our CNC heads.

Now that you are spilling beans, what exactly did you guys do to that muffler that was under Crusher for the T25? I knew better than to ask at the time, but was very curious as to what was going on in there. Someone spent a lot of time sitting over that thing with a TIG

Nothing tricky. Eventually blew out the packing so we opened it up and repacked it. Added more than it originally had to help it last longer and be quieter. It was f'in heavy when it was done but the weight was down low so OK.

For all of our PT cars, we have "PTx map" and "hi-power map". The one we race with and the one we goof of with at HPDE's and ride-a-long demo events. This is the hi power map from original engine we built for 2011 T25 in E2. That motor had coated everything. It ran so cool that we ran a stock radiator and still had to block part of it off. Keith Tanner was one of the team mechanics that year and was flabbergasted by how cool it ran.

It made 174whp on CA91 in October of 2011. Probably capable of a bit more with additional tuning but we weren't after that. This engine in this dyno was capped at 148whp which we made from about 5400 to 8000. We set the fuel cut at 7600 for the 2011 25.

HAHA! Ok, that's cool. I don't remember why but I had to pull that thing off the night before and then benchpress it back into place by myself with limited space. I don't remember who (probably Keith) was under there with me giving me crap while I struggled to get it on the hangers. I remember thinking "Jesus Christ, this is the heaviest GDMF muffler I've ever had to wrangle." I feel slightly more manly now

2011 T25 was 2250 IIRC. 2012 PTC nationals was 2260# with A6's. NASA added weight to that config (closed the loophole we drove crusher through) so we reclassed to 2205# for 2012 T25 but had to run without the splitter. Not enough points for our A6's but they're too soft for T25 anyway. We ran R1R's for 2012 T25, SM6 (R6) for sprint races. Moved some weight around, made some tuning tweaks and ended up significantly faster than it was at Mid-O nationals so a win-win.

edit: 2250# for E2 in 2011

Ha... that was me. I don't remember why the exhaust had to come off, but I do remember that thing being a bitch to get back on!

Emilio, how are you pulling so much power out with just tuning? Timing, vvt, or both? My car with diypnp and BP4W head is the only thing I've ever tuned, and I struggled to pull 5hp out to make my reclass. My timing numbers were getting lower than I was comfortable with without knowing EGTs, and adding fuel barely changed anything. I had a couple friends just do VVT swaps and their tuner said he struggled to detune their motors too, even with VVT.

That shall remain proprietary. Even Andrew doesn't know how I do it. If I showed you Super's PTE map you'd be upset. Keep thinking outside the box my friend. Sorry about mega muffler.

Didn't we have RRs last year? It was fun keeping the snoopers out of the trailer and the R1R endcap on the rack was a brilliant move!
