rotary engine rule size

[immortal_omni]

can someone please hlep me, i would like to know how a rotary engine is classified under ALMS rules or any roadracing rules. i have heard in japan, a rotary engine's nominal displacement is 1.5x its displacement, but i've read online that the mazda 787b was rate at something like 4.7ltrs which was like 1.8x times its displacement. does anyone know what it actually is.

I thought they were outlawed after the 787B and its four rotor rocked every other car so hard, they were like, oh shit, we need to run, so they did, and then the rotary was outlawed, and then God was like, wow, that could take me on, I need to find away to stop it, and then God built the LS1.

Wow, I totally just didn't answer your question at all.

I think they are outlawed in that series, but I'm not sure. I would suggest google, but since my lawyer is sueing google, I wouldn't recomend, so try Yahoo!.

1 rotor is equal to 1.3 liters, which is why in the 13b you see 1.3l X 2 so in actuality it is equivellant to a 2.6

Also for your reference 1 rotor is equal to 3 pistons so 2 rotors would be a 6 cylinder and 3 would be 9 and 4 would be a 12

A.) 1 rotor is 654cc, times equals 1308cc. a rotary engine's output is comparable to 2.6ltr.
B.) you still haven't understood my question, so allow me to rephrase

in terms of what size restrictors are given, a rotary engine is rated different than a conventional engine. in a series like FIA GT/ALMS, anything under 3000cc gets the same restricotr size so it doesn't matter there, but for insttance a 2000cc rotary engine.

in japan, a rotary is designated at 1.5x its displacement, so the rules see it a 3000cc, and not its actual 1.3/2.6 ltr.

according to the information i have found on the 787b, it was calculated at 1.8x displacement, which would make our 2.0ltr a 3.6ltr. in ALMS, that would put it into the 3.5-4.0 ltr class, which a lot different the the <3.0ltr class. thats two class up. now if they go by its actual nominal displacement, it would fall into the 3.5-4.0lts class, thats if the calculations were exact at 4000 cuz 4001cc would make it the 4.0-5.0ltr class.

now my question is, is it 1.5, 1.8, or something totally different.
