Re: Average fuel consumption

Interesting comment but complete crap. The throttle exists to make fuel-to-air ratio combustible in petrol engines, which is in a fairly narrow range compared to diesels. My car has an electronic throttle and I know it quite well as I pull it apart and service it with love and care and sweet tender...

Re: Active Safety in Cars: What's good?

I really don't think you know what you are talking about. It certainly isn't impossible to get that kind of precision out of a big turbo engine, it's just a lot tougher and likely runs the price even further up. That's why I said "almost". As a feat of engineering, it's cool to see that M...

Re: Active Safety in Cars: What's good?

I feel like there's something wrong with me saying this, but... for a high-performance car, wouldn't a supercharger be a better idea? Sure a Turbo isn't always-on, but fuel economy for a Corvette just seems like a lost cause compared to dealing with turbo lag. For something RWD at the kind of perfo...

Re: Active Safety in Cars: What's good?

It's a cool engine, sure, but raw performance isn't everything. How much does it cost? What's its life expectancy? How much fuel does it burn? How many opportunities do you get to properly use its abilities? If you ask me, the most impressive piece of engineering on display in that video isn't the e...

Re: Average fuel consumption

Some TBWs get it down to where it doesn't feel obviously wrong, but IME it's still around the bad end of mechanical throttles (with oversized intake manifolds, that kind of thing). At the good end of TBWs, I can see it being personal preference though; between a non-eccentric mechanical throttle, sm...

Re: Active Safety in Cars: What's good?

Last time I really had fun driving, it was this 142-horse EJ223 in a 2800-pound car, the engine isn't in top shape and is definitely not actually capable of 142, and I still hardly went over 4000 RPM.

Re: Active Safety in Cars: What's good?

It's much more fun to drive a slow car fast than a fast car slow, but small turbos are still great, because who wants to have to go to redline for power when it could be available much more responsively at half that? If I ever get around to doing anything custom with a turbo, it'll be the smallest t...

In defense of semi-binary throttle use ( not power use), my car's BSFC map looks like this , and it isn't too far out of the ordinary .

My R7 1700 and GTX 960 (on Win10 for this) at 1440p high/2xAA can't quite manage 60, and suffers momentary drops to sub-15 when particle effects get heavy.

And yeah, 1.165v was right at the edge. It never was able to do 4.4GHz at only 1.160v. That's probably not worth worrying over, then. Even if it accelerates and degrades that much every 6 months, it'll still have many years of useful life left in it (and the real degradation could have been only 1-...

You may want to double-check the data from a variety of sources again.

The 8700K only...

Re: Would it make sense to replace a GTX 560 Ti with GT 1030?

PCIe bandwidth only matters to high end cards running at low resolutions where the framerate is very high and there are loads of frames to render. This does not sound like a scenario for an entry level card running in an old Phenom. Even if you were to get a GTX 1080 and run it a PCIe 2.0 x4 over a...
