Huh ? Who said anything about pump gas ?

But since you asked ScooT FD3S

13B PP Turbo with a HKS T-51R

1300Nm ?????

Is this 2Fast2Furious torque ?

So the RB25 Engine stock makes more Torque at the wheels than a 700hp Super GT Race car does?

I think your figures are wrong or more likely someone doesn't know how to load a dyno ?

Uncorrected torque is meaningless, unless you post the diff ratio, tyre size (if appropriate) and gear ratio.

(i bet i could make an rb20e make that torque stock, if i ran the right diff ratio and in first gear..)

Maybe we should test my Cefiro. Its a Hybrid RB20DET I think a goal of 1300Nm would be easy if we modify the diff settings :P

4th gear (1:1 ratio) std 4.1 rear end
As per any car without a speed cut.
Measured at the hubs


BTW, 600Nm at the engine is piss poor for 515kw..or is the kw figue 'corrected'??
A GTR with filter, exhaust and 1.1bar will make over 550Nm at the engine with 265kw atw.

We all know Dyno Dynamics correction DOESN'T work.
We had the sales rep blubbering for a reason last year as to why the power figure changed close to 20% when a different gear was used even though the unit knew engine rpm and roller rpm and could hence 'calculate' (if you can even use that word) ratios for flywheel correction.
Both pulls done 4 times, each under his supervision and loading...
Doesn't stand too well when they're trying to sell you $200k worth of gear..

The GTR stock corrected Torque figure is 332Nm for those who care.

Glad we're talking stock cars here.....

Back to my original post: No RB20 makes OVER 1300NM at the wheels from 2800-6600rpm or 225kw atw on a std turbo
:D

Don't quote me on this -

I would believe that torque figure, if it's on a hub dyno.

Rotary, wasn't it a 20B that won Lemans????

I think the R33 didn't finish Lemans because of gearbox
problems, I think it was similar in specs to the 400R.

From what I have read, the R32GTR won the 24 hour at
Nurburgring, said to be - "the beautiest and hardest track
on earth", I think took 25 sec out of the Porsche's lap time,
for I think it was a production car.

If a stock rotary can win a 24 hour race at Nurburgring, that
would be something special.

The 20B was out of the Cosmo.

The 787B (1991 winner) was powered by R26B quad rotor.
There is a really neat video clip of the variable length intake runners in action.. pretty cool for (now) 15 year old technology

I don't wanna turn this into a Rotary Vs. Piston debate cause the truth is I own both and respect both engines for what they are..... Both great engines.

But here are the answers to your questions....

The LeMans Car used a R26B 4 Rotor Engine

654cc x 4 = 700hp + 600+ Nm @ rev limited 8500 rpm

The FD RX-7 won the Bathurst 12 hour production race 5 years in a row. Beating Porsche 911 & 968, Honda NSX, Nissan GTR, EVO & WRX, and Maseratti just to name a few.

Ah I see, learnt something new, thanks dudes. :)

They are both good engines, but I haven't heard
of a stock rotary winning the 24 hour at Nurburgring,
would be awesome if there was one.
