I havent made one yet, on the last dyno sessions I had a air box on the p-port ITB's. The slide throttles are just for testing, otherwise a filter would have been there asap.

Thanks Rice

I for one am very impressed you got this power from a 3 rotor N/A, and I know 100% what it must accelerate like.

p.s. I had a first gen RX7 running S5 turbo engine with T04 at 20psi that registered exactly 472rwhp on my local dynapack dyno that thing was 1070kg and it flat out hauled!

Haha that is a good comparison for sure. Mine is 1077kg, cant get much closer than that.

I like dynapacks they take out allot of variables and just work better than most. I know when I see a figure from them I can believe it

Do you have any more vids? I'd love to see one flat out hauling through the gears

Yeah I like the dynapacks the best. Plus they are made in new zealand

I have some more vids but they are not good, and at the racetrack. Been kicking myself for not getting a gopro and doing a few runs. This spring there will be plently!

P.S. read through your website, its pretty awesome. I love how you tell it straight up. No homosexuals.... lol. I wish there was more actual competition here in the u.s between companies. Our goal is to kinda "nudge" other shops and create what japanese builders do. Use a little trash talking combined with racing to improve the rotary engine ultimately.
