high revving engines

[mikey19]

just curious, what are the highest revving engines currently in production cars?

plz dont count race cars, motorcycles, or cars with motorcycle engines.

I know our S65 can do 8400rpm. The Honda S2000 can do 9000rpm? but I think it is out of production now?

Rx-8's wankel can rev to 9000, but its cheating bc its rotary.

do u guys think our cars have the highest revving engine then? esp for a large V8.

Ferrari 430 Scuderia seems to develop peak power at 8500 RPM therefore at least 1 V8 Revs higher. Nice company to be in though!

[farbarg]

Audi R8 5.2 V10 8700 RPM redline

[devo]

Porsche's MY2010 GT3 (3.8L boxer six) redlines @ 8500 RPM and makes max power (435) @ 7660 RPMs.

4L is actually somewhat small for a V8 as far a production cars go.

As for highest revving engine, I'm pretty sure their are a few track-toy type cars (but production cars nevertheless) using small displacement V8s that hit 10,000RPM or so.

Edit: Here is one example:

Now, admittedly this motor does make the S65 V8 look like it has a large displacement. Also, I realize that RS Performance builds this car, but I believe it is something of a partnership with Caterham.

Lamborghini Gallardo LP560 - 8500 rpm 5 Liter V10
Lamborghini Murcielago LP640 - 8500 rpm 6.5 Liter V12

I guess most is at 8500rpm. I bet our S65 can hit 8500 rpm comfortably too :P
interesting how BMW M chose 8400rpm as the redline

[Lemans_Blue_M]

Farbarg, got it right.

It's the new R8 V10. (8700 rpm factory redline)

This the currently the highest revving street-legal production car. (for now)

I assume the OP wanted to exclude extreme track cars like the Radical.

Caparo T1
575bhp @ 10,500 rpm
3.5l V8

^^^ Another good one.

Here's Ariel's entry:

As an aside, this has to be the highest revving motor with forced induction ever in a production car. Too bad M won't build a V10 or V12 like that.

Oh come on now guys...

Those are extremely limited-production (and very expensive) track/race cars masquerading as street cars. No fair!

Still cheaper than a Lambo though

True, these are extreme. But the OP did say "production cars". And these are not motorcycles or race cars. True, I think some of the V8s borrow motorcycle architecture. But these are definitely no motorcycle engines.

+1 there was no stipulation as to how civilised and by the nature of the question there were always going to be some extreme machines. Also the latest version of the T1 has a button for raising the nose to get over speed bumps so it's practically a Golf

Bottom line the M3's V8 is a fine mass produced engine that's getting close to exotic cars' max revs. The new RS5 will be up there too.

And vale S2000: bit of a bargain and too bad Honda hasn't got a 2nd gen out.

What I find more interesting is piston speed over max redline. When you compare the S65 on that basis there is not much else out there that is higher. In ft/sec the M3 motor is almost identical to current F1 cars.

The Audi V10 has got to be much faster if it is hitting 8700RPM, right? It has a 92.80 mm stroke vs. the 75.2 mm stroke of the S65 V8. I think even the 8250 RPM R8/RS4 V8 would have a higher piston speed given it shares the V10's stroke.

Yep the R8 V10 has a maximum piston speed of 26.9 m/s, the R8 V8 or RS4 is at around 25 m/s. For comparison maximum piston speed of the S65 is 21 m/s.

LOL I agree, haha.
I have never even seen these cars in the US. But yeah I guess they count since they are "in production"

how about narrowing it down to more regular looking production cars with doors and normal car body lol.

What engine will the RS5 have? a new V10?

you guys think our S65 can do 8500rpm or even 9000rpm w/o blowing up into bits?

dude 2.4L V8, sounds like trying to go for a F1 engine. that thing is crazy. If BMW can make a turbocharged I6 or V6 and have it rev to 9000rpm and put that in a M3, that would be a killer. engine reliability would be a problem though i would imagine.

Not sure about 9000, but aren't a few tuners raising the limiter to around 8700?

Thanks south.

For you next homework assignment , what would the RPM of the S65 be if it had a piston speed of 26.9 m/s (Assuming it did not self destruct )?

And Formula 1 engines spinning to 19,000 rpms with a 39.7mm stroke will net a maximum piston speed of 25.14 m/s.

39.7 mm×2×19000 rpm / 60
