Rev happy cars

[TheInsanity1234]

I've got a Skoda Citigo and that seems to be quite happy to rev up to about 5750 rpm, after which it suddenly turns into a noise generator and produces absolutely no acceleration (which isn't an issue, as red line is 6k rpm, so I'm usually changing up around 5.5k anyway). It's a 999cc 3 pot. It's weird, it starts off simply humming until you get to about 4k, then suddenly starts making a tad more noise, but it doesn't sound strained until you hit 5750 rpm.

It's such fun to drive though, although being able to hit 60 mph at the red line in 2nd is also quite convenient when I want a lazy buzz up a slip road to merge.

A pair of twin cam.





You need to work the s14 to get the best from it.

320is running the s50/3.0 from the later M3 was another rev happy unit and made nigh on 300 brake.



A 2.7 m20 with a lumpy cam and triple Webers would rev with ease. (awesome noise too!)

Can we put some numbers to "high revving?"

IMO :
4 cylinder cars : over 7,500
4 cylinder bikes : over 10,000
2 cylinder bikes : over 7,500
v8s : over 6,500

The 6.2 in my CLS make peak power at something like 6,800rpm so that's pretty revvy.

My old Clio 172s suddenly came alive at 5,500rpm. Slight contrast in these cars but both love to be revved.

That isn't a particularly high number for a 4 cylinder bike. The old CBR250RR used to do 18,500rpm although it was a bit of an engineering marvel. Even my 19 year old 955cc triple Daytona will whizz past 10,000rpm.

I just last night bought a SportKa.

That thing likes to rev. It's also about as loud as a jet engine when it does it.

My old Puma 1.7 was even revvier, mind. I loved that thing.

I thought it was pretty well known that the Ka engines were breathless old Anglia derived engines. The Puma doesn't mind being revved but the 1.8 SRI Corsa felt much happier to be revved I thought.

The 1.3 was the old Anglia derived engine, and a horribly tinny tappet sounding thing it was too. The SportKa (and StreetKa) had a 1.6 Duratec engine. Although it only developed 95bhp so not sure it was particularly revvy.

True - I'm a bit tired tonight.

Big twins/4s : 9,000 / 12,000
Small twins/4s : lots

Better?

To me, a revvy engine is one that is happiest at the upper end of it's rev range, it doesn't have to be objectively a high RPM. For instance, many modern turbo engines prefer to operate at comparatively low revs, feeling breathless as they approach the limit, even if that limit is over 7000. In comparison, earlier generation 16v NA engines felt weak low down, needing the turbulent high airflow to be able to generate power.

We need more BDA goodness! I know it is cheating by virtue of it being a racing engine. But finding one still in road legal spec ain't easy

Edit because I left out rotaries. Never tried one but jeebus christ i would love to drive the st out of an FD.

I actually think that a standard FD isn't that rev happy. Smooth for sure, but the turbos constrict it at higher revs, and there's not much rasp to the exhaust note.

Lordy, the S54 delivers Peak Power at 7900 doesn't it?

The Coyote in this sings pretty good for a large V8


The Voodoo in the GT350 is properly mental though.
