2014 Mercedes Cla 45 4Matic Amg Vs Hsv Gen-F Gts
brettenator replied to timetaker's topic in General Car Talk
20% power loss from flywheel to wheels sounds about right, it's what my car got. -
You will need to know the diameter of the dyno's roller. Apparently they're usually about 218 mm or 273 mm, so that would be 872 Nm or 1092 Nm. As you can see, the torque figure isn't very useful, as it's distorted by many components along the chain; roller, wheels, lsd, torque converter if it's auto, and the gear selected. Derived torque is something that resembles the source.

Lower Grill With Small Holes
brettenator replied to brettenator's topic in Interior & Exterior Workshop
Apologies I didn't see this sooner. It's just a cheap generic one, from Repco or something, needed cutting to fit. It's not one of the Ford ones you see sometimes. -
Hi guys, I was curious if anyone has any experience with these tyres, I'd really appreciate hearing some. Thanks, Brett.

Best Wheels For Big Power - Traction
brettenator replied to The Kerb Warrior's topic in Wheels and Tyres
I need 4 fresh ones, thinking of sparing no expense on the rears and getting something like Michelin PS2s. Can I get away with something really cheap on the front? Like Achillies? Also what's the max width the factory 18"s can handle? Cheers guyths. -
It's called kipping and it belongs in the trash also
-
Done that a fair few times lol I was asking because the majority of the pros do wide stance squats. They preach wide stance for box squats and free squats and being the stronger method, and also the one that develops more muscle. It is a bit home-o to have a bicep/tricep day, but nothing wrong with sneaking in a few curls just to be safe haha

Top Gear Australia - Renault Clio Rs Vs Fpv Gt

UK version is OK show but absolute snoozefest during those segments where one takes public transport, the other drives to a certain destination. -
To Oil Pump Gears Or Not To Oil Pump Gears...that Is The Question!
brettenator replied to Pazzo's topic in General Tech
What's the point of having the cold and hot viscosities of multigrade oil then? -
To guys like Goliath and Adamski who are squatting decent numbers, could you describe your technique? Are you doing wide stance?
-
I'd say most likely he's using a machine with a number of pulleys that has 50 kg selectable via a stack. Sounds stupid to assume that someone would think a machine is directly comparable to free weights but I've heard it happen before.

Unless you're entering a bodybuilding competition or your calves are freakishly thin there's no point to doing them. For hamstrings, the best exercises are Glute Ham Raises, Leg Curls, Romanian Deadlifts, Good Mornings, Pull Throughs, and 45 deg. Hyperextensions.

That's a nice time for 380 hp. But from what I know (not a lot), changing the stall speed shouldn't affect the power over the RPM your transmission stalls at.
-
Just a guess because I obviously haven't seen you bench, but it may be wise to change your form so the bar touches lower on your chest (towards your stomach), and you tuck your elbows in more. It's very common to injure a shoulder bench pressing with flared elbows (upper arms at ~90 degrees to the body). You may not be able to lift as much weight like this but over time you'll get used to it.

Unfortunately not mate, but add him on facebook, there almost definitely will be some.

The funny thing is he used to be like, anorexic skinny.
-
He's a mutual friend, I think his name's Jay but I don't really know him. Why you ask?

It's important to keep warm, especially in winter, as blood will be drawn away from your extremities and muscles towards your organs. You'll often see videos of pros doing, for example, a clusters sets of squats in a sweat soaked hoodie.
-
Nice one, didn't expect to see anyone doing 531 here. 220 1RM ain't bad, what did you get for the 5+ set?
-
His torque and motive force numbers don't correlate at all... Unless the dyno used had a roller over 2 metres high, 2444Nm has to be a typo... The motive force is ridiculously low as well
-
It's nothing to do with distance traveled, it's the force (in Newtons) that the tyre applies to the roller (that has a radius in metres). You multiply them together and you get a torque value as a result. Clearly, a larger roller gives more torque. Think of using a screwdriver; if the handle is really thick, when you use it you are generating more torque than you would with a thinner handle. This is evident in that the decrease in effort needed to loosen a tight screw is proportional to the increase in screwdriver handle thickness.
-
Sorry mate I forgot that I wrote in here. I don't really need to contribute, others have already given accurate responses (e.g. groper), but there are a fair few posts that seem to describe the misconception that torque and power are two separate ways a car can generate forward movement.
-
Interesting that they advise against doing this 'mod'.
-
You have a peak torque of 859 rwNm at 116 km/h (or 3136 RPM). This is assuming that peak derived torque and peak roller torque occur at the same RPM - I can't think of a good reason why they wouldn't, but maybe ratter could lend some insight.
-
Unfortunately this is not correct. Torque and Power are not two separate characteristics of an engine that independently affect the way a car performs. They are both a description of the force that a motor applies to a crankshaft. The greater the force on this shaft, the greater the acceleration of the shaft's rotation (it will gather a higher rpm in less time). This force is the only thing that makes the crankshaft spin so therefore both power and torque figures describe the same property of a car.
