What to get: 2006 Z06 or 2006 911 S?

Never.  The teams only are allowed 8 engines per season.  They are sealed and can't be serviced.  There are 17 races in the championship so each engine must last two race weekends.  That includes 3 practice sessions, qualifying, and the race.

Edit: The drivers do complain that there is distinct lack of power toward the end of an engines life.

soo, 10 runs in the life of the engine...how many hours is that?

point being,  they are ringing the engines up to 19,500 RPM but they don't need to last a hugely long time.

2000 Silverado and I DIY'd.

I was doing the front brakes and while I had it on the lift I decided to investigate why my AC wasn't working as well as it should.  I found the melted belt laying on the pulleys.  Thinking the compressor seized I walked right out and bought the compressor (you can see how I learned my lesson) as I already had an AC charging manifold on hand.  I took it to over to my buddys house (Corvette nut and one of the guys I fly with) since he had a better workspace.  We took the compressor off and went through the hard part only to find that when I was mounting the new belt that the old pulley had gone to hell.  Doh!  Called up a couple stores to find one in stock and 30 bucks later we were done.  Turns out I didn't need a new compressor but what the hell I have a new one now.  2-1/2 cans of 134a later I had plenty of cold air to help combat Die Hard's hot.

Easy enough to do and total work time was less than 2 hours not counting running out for parts.  Afterward we BBQ'd and watch the meat bombs fall from the sky at Cross Keys from his porch.

aaahhh.......that wasa the one that had the 4x4 light on too, right?

what fixed that? was it the switch?

[CAP1]

Reminds me of the time the water pump went out on my Subaru.  I got the water pump and a manual.  Then a realized the darn thing was driven by the timing belt.  

I was able to get the job done.  Took me about two hours....times three.

subaru timing belts are gravy. i could do them all day long....and i HATE doing timing belts.

Ford designed and built it fairly recently, touting it as the tech platform for the next couple decades of ford motors.  Sounds to me like they made it as advanced as they could.  The SOHC version goes in more vehicles, the DOHC is only in the mustang, and at first it was only in the cobra.

look At the SOHC 4.6, and a SOHC 427 side by side.

they're a LOT alike.

Yeah, but why are they doing that if torque is all that matters and RPM means diddly? Huh, CAP?


HP = TORQUE x RPM /5252

although it;s nowhere near the power output of those f1 engines, my 5 liter that used to be in my 89 mustang(it resides in a fairmont now) is still un-rebuilt from 1989, and will still run 12's all day long. and i can drive it anywhere anytime. and it will  cruise the highways very nicely.

they are using rpm to make up for lack of size. there's no way a 2.4(i think?) v8 can make the power that a 5.0 or a 6.0 will. there is no need to run em that high.

most winston cup teams make in the ballpark of 750. they do it with 358 ci engines....usually below 8,000 rpm. they haul 3400 pound cars around all day long at close to 200 mph. if the sanction body would let em run without the restrictor plates, they'd easily top 200 mph on the super speedways.


torque is what moves your car.  you know it, and i know that you know it.....you just refuse to admit it.

Yep.  New switch, 2 minutes and no more problems.  Thanks again for the informaton.  BFR still on me.

i tried that on my dyno..........but my dyno isn't for rating horsepower...it's for emissions testing. i got a little over zealous shifting.....i slammed 3rd gear at about 5800 rpm......blew the belt right off the dyno. 

[CAP1]

Yep.  New switch, 2 minutes and no more problems.  Thanks again for the informaton.  BFR still on me.

that is much appreciated sir.


i'm actually just glad i was able to help ya out, and save ya some money.

i shoulda thrown a chevy in there too, but as usual, i was/am multi-tasking.
i can't put a dodge in there, 'cause it'd be a viper....and they make the most annoying bbbbzzzzzzzzz

[straffo]

i know that.

but the combustion process does not create kinetic energy. it does create something, but not kinetic energy.

sorry ?

Remember Mayer and Carnot.

You missed the part where energy can be converted .

I think they put between 1,600 and 2,000 Km on the engines over the course of it's life.  The drivers have complained about a noticable lack of power when the engine is on it's second race weekend.  So no, not very durable at all.
