I captured some audio of 5.7 L "engine noise" that you all are free to sample. It is at idle (warm engine), towards the front of the car, and near a hard reflective surface (to really enhance ticking...

If you have an exhaust that kills v8 drone (i.e., the stock exhaust), then it's not likely you would hear mds mode. The anti-drone essentially attacks the same frequencies that would tip you off to...

I don't think that is what the OP experienced, anyway.

Suffice to say, if you are stuck in a situation with one wheel's worth of traction on hard launch to race a Mustang, you aren't going to win...

Under normal traction conditions, there is no reason for one wheel to be spinning all by itself on this car on hard launch.

All I can say is...don't believe what I said up above, go and try it for...

I'd almost say I'd take the noise over the alternative. ;) No need for it to have to be a straight-cut gear set either, right? I'd think in this day and age it would be possible to come up with...

Given the context that made this discussion topic possible, chain designs can be just as vulnerable, it seems. The real issue is the "interference design" which is not uncommon in engines over many...

Roy gee, I don't think traction control would have made a difference for you either way. It was your launch, plain and simple (not to bust your balls, but I think that is what you need to hear). ...

Yes, I believe that is how you would leverage higher hp...but it has to be the type of improvement (more torque going to work) that is actually increasing your trap speed. That is what will burn...

Fwiw, the 1969 426 Hemi Charger 4-spd did indeed use a 4.10 axle. The modern day Tremec is not all that different from the A833 4-spd from that era, as far as those first four speeds. You could...

The only advantage of ohc is to exploit an extended redline. If you don't hit the extended rpm, then you don't get the benefit at pk hp. Given that context, a properly leveraged ohc engine seeks to...

Certain misconceptions seem to always recur in these Tesla discussions.

The suspicious side of me wondered if that rebate offer only applies if you buy them in the individual quart bottles, rather than a 5 qt jug.

Well that is certainly true...there are multiple ways to approach a dyno test, for sure. Are you doing it more to get a crank hp estimate out of it, or to be more comparable to other "standard" dyno...

The 1:1 being special is a mystery to you? Really?! It's very simple. The absence of gear reduction (1:1) means the mechanicals are locked together as a single unit. Hence, there can be no loss...

You make a good point! I could swear I've seen it below $25 before. That's why I was "waiting". I suppose $26.60 isn't so far away, if you really get down to it. I guess I get too...
