This morning I've been watching a repeat of the Grand Am Watkins Glen 6
hour race.(thanks Speedvision)
Several of the cars run a V-10 Judd engine. I think that used to be a
Formula 1 based powerplant. It sure sounds like what I traditionally
associate with F1 engines. The modern Ilmors and Ferrari's and BMWs, while
certainly powerful, sound tinny. The Ferrari 'used' to scream back when it
was a V12, but now the high pitched whines, espeicially from the Ilmor
Mercedes, are almost distracting.
In kinda of a side note...the IRL cars, have changed somewhat, they used
to have a deep braap sound, now they resemble the Turbo cars of Cart
somewhat.

Really?
All I can hear is the rev-limiter.

Hi Dave,
Most of the IRL engines are now using flat (180-deg.) cranks, which changes
the engine 'note'dramatically.

note too ,much higher pitched then when they started.You ever noticed how
the different the McLaren sound's compared to the rest of the V-10's?

That's more to do with the exhaust setup than the crank order. There's
an excellent article at
http://www.speedvision.com/pub/articles/racing/01formula1/010502a.html
that explains what McLaren is (probably) doing. The article is by Steve
Matchett, ex race mechanic for Benetton...

I dunno 'bout that... When I was at Indy last week they sounded about half-way
between a Cup car and a ChampCar.
When the IRL first started it was using 4.0 liter motors, but have since
reduced displacement to 3.5 liters. I'm sure that's got alot to do with the
pitch change as well...
Warlock!
Yes, when you go to a 180-deg. crank, it changes the firing order
completely, which means you need new exhaust plumbing.

introduced at the 2000 Indy 500, where some cars had it and others didn't .
HUGE improvement in the sound of the cars.

All F1 engines have a flat plane crank, he meant the Ilmor engine sounds
different to all the other V10 flat plane crank F1 engines because they
plumb the
exhaust up in a different way to everyone else.
That article is quite interseting BTW.

Try at least going to a real F1 race before giving an "expert"
assessment of it's engine sounds. TV does not come even close to
being able to demonstrate the outrageous sonic power of these
powerplants. When you're on the circuit the engine has a booming
lower end which combined with the screaming wail of the higher end
overwhelm your auditory senses, get under your skin and make the hair
stand on the back of your neck. In no way does it ever sound "tinny".
The only thing that does is the sound of the car engines for the
junior single seaters and GT series that usually run as a prelude to a
F1 race.
