i am just waiting to see a strap break in this new trend of dyno racing
ehhhh, not sure I would feel too comfortable doing that :eek:
Jeller
i’d need a ton of open room infront of me to do that just incase i got free
Or just really stupid.
i wonder what would happen if you just slammed on your brakes on one of those things, while at 100+ mph? would it just stop, or would the rollers try to throw the car back?
Those straps are extremely strong and can handle HUGE loads. That webbing is also very good with sharp, shock loads. You will probably not see the strap itself break, perhaps the ends, but there are straps that can certainly handle the load the car applies.
However, what concerns me is that where they connect the straps to the chassis. It’s putting massive loads on parts of the car that were never meant to see it. It’s only a matter of time before we see a video of someone doing a launch on a dyno and tearing off part of their car.
Also, people who leave comments on youtube are fucking retarded. 90% of youtube comments need :picard:
anti-lag^^

What sounded like spooling right before his launch?
(brakestand? dyno spooling?)

it’s antilag. In a true antilag the ignition has a massive advance so that it actually ignites after the exhaust valves are open. Then, instead of using all of the combustion pressure to force the piston down in the power stroke a portion of the generated pressure then exits into the manifold and spools the turbo. It’s pretty hard on parts, too, especially manifolds and turbine wheels.
There is also a more common antilag, that’s a 2 step rev limiter. Here there is no advance, but what happens is that in order to keep the engine from revving past a certain RPM, it cuts the spark. The unburnt fuel is then pushed into the exhaust manifold. By this time, the engine rpm has dropped a little bit and now the spark plugs fire again. Well, this time when the exhaust valves open, the heat of combustion ignites the fuel that was pushed into the manifold and that secondary explosion spools the turbo. This isn’t the “real deal” antilag, so to speak, but it’s simpler .

that CANNOT be good for a turbo

I’ve read that it’s actually more detrimental to the manifold.
i was thinking that as well. when the explosion occurs there is definitely a lot of heat and pressure generated of which the manifold is defintely not designed for.
YAY for flames out the exhaust! Says the kid in the background…lmao He made the vid. worth it.

Antilag uses timing retard, not advance to burn fuel later in the cycle so it partially ignites in the exhaust manifold. I know you know this and you just typed it backwards by accident, but just to clarify for everyone else… It also generally involves air injection.
Also a 2 step is a rev limiter and is totally different than antilag. It can be spark cut, fuel cut, or a combination of both as well as cutting single, multiple, or all cylinders at once depending on how you set it up. This isn’t designed to burn fuel in the manifold by altering timing, but if you’re cutting spark and not fuel on one cylcle then some of the fuel gets pushed out on the exhaust stroke and on the next cycle that fuel will get ignited in the manifold.
You are correct about the straps. As long as they’re not beat up they can hold a lot more than you’d guess.

Yeah, i meant retard. i’m a… fool…
And that’s why i reffered to the 2 step as “antilag… but not really”
bang.
Like I said buddy…I know you know what you’re talking about. I just don’t want others to be confused by what you said. 
Those were decent bangs. Skrapper and I have seen better.
