FD RX7 with 570bhp and 590lbft without a V8 or 2J in sight.

Apologies if this has already been posted.

Crazy car, there is a few cool build pics online too, Not really an rx7 is it :s

[StavFC]

I\'d love to see the build pics if you have a link

[turbo boy]

sounds like a 4 cylinder cossie

[Grant Monkhouse]

Not a rotary can\'t help but love the pop bang whistle of the engine turbo setup

[re japi]

It has Nissan 2l turbo(4 cylinder), Skyline gearbox and 4wd drivesystem and Mazda rear diff. She does sound amazing and goes like mad.

Valtonen Motorsports has been building it. He has done trackcar from FD with similar engine. Dont remember how much power she had, it was like 750hp...

[festa]

the guy doesn\'t use the clutch alot only seems to use it when changeing up at full power?

[CharlieP]

Well I am disappointed,the title couldn\'t have been anymore misleading after all lol

[StavFC]

Not a rotary

No, a little 2litre SR20 I\'m afraid.
 
I\'m not sure if 13Bs are legal in rallycross supercars, but to be competitive with the big boys you need around 600lbft of torque or more (this car has 590), the top guys have almost 700lbft.

[Grant Monkhouse]

Is this stav I was talking too on FB about rotaries and torque? If so mate if you want to see my rx4 turbo, check out my build in the old skill section;)

That torque is just mental, I wonder what it would be like without the inlet restrictor?!

[StavFC]

Oh yeah. I\'m presuming by that last discussion then that these rallycross guys are idiots who cant drive, and they just need to learn to change gear rather than needing that torque to be competitive, lol.
 
RX4 looks v.good, I like old skool rotaries.

haha touche. cant agree more about having torque TBH but getting 3 bar into rotaries might not be so easy holding it together but would reduce the necessity for porting and keeping the power lower down.
 
I know Rice Racing is pumping close to 2 bar on stock ports pre turbo WM50/50 etc and hes close to 650 hp by his in car equipement, or there abouts.

[Will66]

Stock ports on AI with a huge turbo would give reasonable torque.  However if you want more torque, go 20B, imagine a 20b turbo with AI!

[oyvindjs]

The only way a rotary can give more torque than HP, is if you run 35+ psi and stock ports etc....
Rotaries are HP engines, and HP is what wins races, simple as that!
Whatever engine you talk about, around 5000-5500rpm,  the HP curve cross and pass over the torque curve. After that, its all about horsepower...
And lets be honest, how often do you drop under 5000 rpm when racing?

Why else would race-engines, racebikes, formula-1 cars etc have tons of HP and 37,1lbs of torque?
Torque makes you weel spin of the line, HP wins races..
nuff said.

[turbo boy]

In long distance racing torque would be more useful than hp. (le mans 24hr)
