I "thought" I had good throttle response.

Until I watched this.

WOW that is cool!

[shaneschevys]

Cool

[kyull67]

I want one.

[Spray-Bomb]

That ain't no kitty, it's monster... Did you here it bark

I'm stealing one and putting it in my Volkswagen

[bryanw1968]

I just had to watch it again. When it's idling it sounds like a really pissed off dog!

[project1971]

thats crazy! quicker throttle response then my bike! holy cow!

[Spray-Bomb]

Just a little trivia

Some of the engines in those cars are so advanced that the team doesn't even own the engine

I think it's the Mercedes engine, the team can only lease the engine

[70rs/ss]

rotary engines with no swinging parts like a rod or a piston, turning in excess of 15,000 (yeah that many zeroes!). They have excelleration just like the throttle response. Just think the fastest rod/piston motor turns around 9,000 (Nascar and drag racing) 15,000 is insane, which is why it sounds like a chainsaw on nitro!!

[bryanw1968]

That motor is turning 19,000RPM!!!!!!!!

My dad used to work a dragstrip and there was a guy who had a 68 camaro with a smallblock in it, claimed to have about $35k in it(back in the 80's!), anyways supposedly the biggest tach you could get back then was about 12k, and this motor would bury the needle on it, so there guessing it would turn 14,000rpm, and it ran just fine and didnt miss a beat. He'd sit on the line with his foot to the floor and just dump the clutch when the green light came.

[70rs/ss]

I used to know a guy....




I think 9-10k rpm is the limit (Top fuel Dragster: Weight: 2150 lbs. With Driver: Wheel base: 296 inches: Fuel Capacity: ... ENGINE: Type: Keith Black Aluminum hemi: HP@RPM: 5000@8000: Displacement: 498 c.i. Bore/Stroke), but I might be wrong, heck I probably am since F1's don't run rotaries anymore right? Heck just ignore anything I posted its all wrong cause wilpedia says so. Well, I think that motor in the vid is a rotary, they may have changed (Not snotty enough to give two $h!t$ about F1) but the one in this thread is a rotary.

It might be a rotarty, I wasn't there. Just thought it was cool so I decided to post it. Definitely not a snotty F1 fan either. Just a fan of motors......
Geez.

Modern production sportbikes all have redlines well over 9k. My '01 1200 Bandit (which is classified as a standard) reds at 11,000. The 06 Yamaha R6; quoting Barry Winfield @ motosavvy.com

I don’t know about you, but 16,000 rpm (and the 112 rear-wheel horsepower that accompanies it) is perfectly adequate for me.

The R6 weighs in around 420lbs

motosavvy.com on the "06 R6

All piston engines.

To the best of my knowledge, (which regarding F1 ain't all that great) F1 has never used rotary engines. there was a FM (Formula Mazda class though)

I guess since we were talking about car engines I thought everyone would assume we were talking about cars, but I later mentioned v8, Nascar, and drag racing and threw in the part about bikes (aknowledging stock CBR's and the like spin to 12k rpm). A V8, V10 (not F1) maxes at about 9k rpm. If you can find me a conventional V8, v10, v12 (again not F1) that spins over 9K rpm then I'll be impressed. From what I got from the F1 stuff is that they are super small displacements (smaller parts means lighter) like V10-12's with 3.0 liters. Are they like 12 cylinder weed wackers? My weed wacker spins like 15-20,000 rpm X's 12 still wouldn't be impressive in a car. All joking aside, a V10 that dispaces 2 or 3 litres, the pistons must be pretty small and then that makes sense.

Fair enough, I guess since I own bikes as well as cars when talkin' engines I think all engines including weed whackers. although I didn't mention my Nova rossi nitro burning 2-stroke that'll spin up to 43,000.

By conventional I assume you mean a pushrod motor? Then yes, most top nascar and drag teams are are up around the ton and I believe they are still using pushrods.

Comp eliminator sportsman drag racing engines turn 10-11,000 rpm. They are 331Ci and less and put out close to 900HP.
NHRA pro stock engines 500CI run at or above 10,000rpm. These engines are naturally asperiated and must run carburetors on race gasoline.

To keep raizing the bar of performance, with all of the limits of the class,the only way is to keep spinning them higher and higher. With the invention of better materials and machineing it allows them to keep pushing the limit of RPM's

[kenm78]

Whos got the marshmellows its smores time cook it on the exhaust.....

[84_4x4]

that was pretty cool i would love to see a rotary engine run in person we've got one at school but it don't do nuthin but sit there so kinda hard to see how it works

[bryanw1968]

I'm pretty sure that is a V8.

Here is what wikipedia had to say about it:

2006

For 2006, the engines must be 90° V8 of 2.4 litres maximum capacity with a 98 mm maximum circular bore, which imply a 39.7 mm minimum stroke. They have two inlet and two exhaust circular valves per cylinder, are normally-aspirated and must have a 95 kg minimum weight. Previous year's engines with a rev-limiter are permitted for 2006 and 2007 for teams who can't obtain a competitive V8.
Pre-cooling air before it enters the cylinders, injection of any substance other than air and fuel into the cylinders, variable-geometry intake and exhaust systems, variable valve timing are forbidden. Each cylinder can have only one fuel injector and a single plug spark ignition. Separate starting devices are used to start engines in the pits and on the grid.
The crankcase and cylinder block must be made of cast or wrought aluminium alloys. The crankshaft and camshafts must be made from an iron alloy, pistons from an aluminium alloy and valves from alloys based on iron, nickel, cobalt or titanium. The complete rules are available from the FIA Formula One world championship regulations. [4]
This is leading to a power reduction of around 20% from the three litre engines. For example, Toyota F1 announces an approximately 740 hp output at 19000 rpm in its new RVX-06 engine [5], but real figures are of course difficult to obtain.

I might be way off here, but didn't the guy who invented the rotary motor try to get Honda to put it in their cars?

[RetroSBK]

Thats no rotary, and its WAY past 19k...

We have worked very closely with Del West (the guys that make most of the F1 valvetrains) and the current F1 engines turn over 22k. Im told that Honda has a motor they can run on the Spintron to over 27k but current fuel wont burn past about 24k. BTW, no valve springs, all air baby, and the greatest gains they have made in the last 5 years have been from the reduction in friction... One place that limited rotary technology besides the wipers.

We spin our supersport motors to 18k (600cc and about 125hp) Superbike motors are 15k (240+hp and 1000cc's) Our motors are FAR more square than a F1 motor.. think that the v10 engine is only 2.4 liters, and has a SUPER short stroke... we have 4 cyl and 1000cc

But you couldnt even imagine the cost, even to build a superbike motor...

Rods are $1500ea, pistons are $1k a set, without rings or pins, Crank is 5K, radiator is $8k... But the real expense is in the electronics... Our Motech traction control system is about $45k, but also has 128 channels of data, although we cant use telemetry during racing, only testing.

Thats nothing....look what these guys do now

This is throttle response.
http://www.youtube.com/watch?v=XR7aF4hY9rU
(Watch the last half of the video).


Nothing goes 0-60, 0-100, 0-200, 0-330+ faster on land.
Top Fuel Dragsters are amazing.

I must concur though - the RPM's at which Forumla 1 turns is amazing. It is so much more amazing than Nascar in my mind in terms of engineering. People talk about how advanced a Nascar engine is - it is not much compared to those.

I'm a big fan of ANY type of motorsports, whether its roundy round, left-right, straight-line, pavement, dirt, water, air, ect. I have the highest regard for the engineers and crews that maximize the dynamics of these vehicles, giving the tech restrictions imposed.

NASCAR engines are forced to meet a very strict engine formula, and while they may not have the latest tech advances incorportated, I'd rather not say that they are not as highly engineered as any other race motors.

F1 and Top Fuel engines are amazing, but let's see 'em run 200 mph for 500-600 miles at Talledega or Atlanta...
