I was in Poland and for my 25th birthday my family gave me a track experience with a Lambo Gallardo. However the Gallardo unexpectedly suffered engine trouble  and was stuck in Vienna for reparations. So instead the driving experience company offered me Nissan GTR and 911 C4S drives as replacements, not as exotic as a Gallardo, but who cares it was amazing! They also have a KTM X-bow, and next year they are getting a 458 Italia. I'm already planning to go back next year    The driving instructor was such a nice guy, a true petrolhead.

Slavvy posted:Yeees, all this is true, but if you compare the firing order of an LS1 or 6.1 hemi or a BMW s60, it's different to that of an SBC or an old school hemi or a cobra jet or whatever. Literally the cylinders fire in a different order. Yes, two cylinders are switched. It doesn't make much of a difference in sound. 1-3-7-2-6-5-4-8 vs. 1-5-4-2-6-3-7-8. It still has an unbalanced exhaust flow.

Motronic posted:Really....being a Porsche guy I have to add that the 928 is the most expensive regular production car Porsche has ever made to date (inflation adjusted). The 944 is a Cayman in modern terms, with the 924 being the Boxster. The 928 would be closest to a current day Panamera (the 928 was slated to replace the 911 so it doesn't have a true current parallel as a true GT car). Owner of a Porsche 928, the one with the V8 it in it....

I can definitely tell when it's an LSx vs an old school V8, particularly when said LSx is in an older chassis. Not as much as the difference in sound between a flat-plane and a cross-plane, I'll grant you.

Some teams would run exits on both sides and when the cars went by on the track you'd hear one bank of cylinders firing. Some cars had the traditional American V8 rumble, others would scream by sounding like a European exotic.

I thought they still did 180 degree headers / something like it for the plate tracks, or am I crazy? And that Chevelle is awesome.  "Short shifter? Why would you want that?"

IOwnCalculus posted:I thought they still did 180 degree headers / something like it for the plate tracks, or am I crazy? Flat plane refers to the crank pins being offset by 180 degrees, whereas cross-plane V8 crank pins are offset by 90 degrees. Looking at the crank from the front, the crankshaft looks either to have a literal flat plane or like a cross, respectively. IIRC, cross-plane V8s are essentially two odd-firing I4's smacked together whereas flat-planes are essentially a pair of even-firing I4's. EDIT: also, flat-crank V8s are pretty much used in racing applications in Europe and Japan but are also THE V8 used by Ferrari. Cross-plane V8s are the default for production cars as flat-crank eights are expensive to design/make because they require balance shafts to prevent them from tearing themselves apart.

If Smokey didn't try them no one did Indy used them a ton, though, like the Ford Cammer.What I was referring to is a "true dual" exhaust, where one header was piped out on each side with dumps right in front of each rear tire. You'd get the impression of a big bore screaming four cylinder in the stands/on TV or in the garage because only one bank of cylinders would be firing at you.

VikingSkull posted:NASCAR never used 180 degree headers, at least as far as I know. If Smokey didn't try them no one did They've pretty much always ran an x-pipe pipe after the collectors, though. Helps with scavenging, keeps exhaust velocity up because they can run smaller primaries, and relieves the excess pressure from the uneven firing order. Seen here in normal NASCAR circumstances:

Whoa. Hold up. Where was that car show? Is that a red 67 Chevelle next to the monkey vomit green 72 1/2 camaro? If so, there should have been a SS 454 Chevelle nearby. If so, that Camaro was mine in high school. My dad's buddy takes them to shows all over. The 454 is my dads and the 67 396 will be mine soon enough. The Camaro is owned by my dad's buddy since I wrapped around a tree when I was 17 in 1998.

This may not be very AI to you guys, but it's pretty loving AI to me. Just picked this up yesterday:  Need to get a few things done right off the bat (fluids, filters, try to figure out where the gently caress the speedometer needle went...), but it's solid and runs really well. I probably start the big projects with it next year once the funds recoup a bit.

Boaz MacPhereson posted:This may not be very AI to you guys, but it's pretty loving AI to me. Well I figured out where the speedo needle went... It snapped off and was laying in the bottom of the gauge cluster. I've got it all apart, and the actual shaft that the needle attaches to is broken. I've got a little stump of shaft still stuck to the needle and the rest running down into the actual speedometer mechanism. All I need is the mechanism itself or at the very least a new shaft and needle. I'm having no luck at all tracking down anything less than an entire new speedo for $200+. Anyone got any ideas?

German "arbitrarily unique" requires you have a special type of socket that costs 10 times the part you're replacing, and/or deal with loving plastic cooling systems.

A lot of the seemingly outlandish poo poo BMW and MB do is actually just pioneering immature technology. Everyone thought BMW was mad putting alloy heads on production cars in the 60's, and the results were catastrophic. Now ever car has an alloy head. Practically every car now has a plastic cam cover, a plastic thermostat housing and so on. Every car has throttle by wire. Lots of cars have radar cruise control, every car has an ESC of some description, lots of cars have lane collision avoidance, practically every car has pyro seatbelt pretensioners, the list goes on. All of this stuff was blanket implemented by MB and BMW very early on and the perceived reliability of the vehicles suffered as a result. I can't excuse VAG though, that poo poo is whack.
