4 rotor *Flames* 8 Throttle 26b Testing @ Defined Autoworks Mazda Rx7 Rx8

[@rickcupola6262]

I'm curious if direct injection with rotaries is viable for the performance rotary scene, since Mazda implemented that technology in their range extender rotary engine.

[@Luminous65]

Whait, 4 throttle for side port and 4 throttle for perifferal port?

[@GTORx7]

You got it. Staged at 50% throttle

[@hong1ru]

@@GTORx7what’s the purpose of this intake system as opposed to a traditional peripheral port?

[@mexicodelcorazon]

My dream car is a 4 rotor fd similar to yours and the body kit I’ve been into Mazda because the rotary engine and their race cars I will one day order a 4 rotor from you guys and a similar body kit to that of a jgtc rx7

[@deleter1823]

id spend on a 4rotor anyday hopefully i come back here with that soon idk a year maybe

[@fabianfranzmann541]

Will it have one big airbox or just an open intake or two different sized airfilters?

[@s2o527]

Insane!

[@bobdavis2807]

make video of the build

[@GTORx7]

Coming soon, just need to upload

[@josephstearn3393]

P51, like the plane?

[@Johnwalter1044]

I'm interested, is there any gain to include variable exhaust lenght or diameter? Like how it's important across the rpm range for making power and torque with intake, maybe such a system for the exhaust could improve performance as well?

[@FukU2222]

Yes but actually no (probably not really worth the effort considering the amount of engineering//materials needed//weight and complexity)

[@FukU2222]

There is a 'book' (more like an 'infozine' if that makes any sense? Not exactly a book, it's about the size of a traditional 'magazine' (albeit a bit longer) but in the format of a text-book per-se?) called; "Street Rotary" by Mark Warner - it goes quite in depth into designing intake/exhaust runner length(s) if you want some more info.

[@dantinhoorienter]

Hello, can you inform me if your RX7 FD3S has short life in engine? By what i know, japanese RX7 FD3S does not waste the engine. Is your upgrades in engine lasts a lifetime?

[@GTORx7]

Very long engine life. I have ran it almost 9 years before recent rebuild. Inside condition showed that it could have gone much longer.

[@Moto_]

Oh my!

[@Deep42Thought]

what's the point? don't get it

[@FukU2222]

4 rotors, 8 ITBS - straight through, P51 style exhaust. What's there to not get?

[@babisotonggg]

wooooo

[@Coffe-]

WHAAAAT did you say!? Sounds like a v8 almost

[@Deep42Thought]

you mean like sh*t ?
