Message: <blockquote data-quote="shiroitenshi" data-source="post: 3050144" data-attributes="member: 27518">It seems like most people thinks that the more powerful the car, the easier it is to launch.I'm not sure about anyone else, but when talking about more than 200hp, I find that commonly, the launch would more often be.Launch at various RPMs, then find the wheel slipping, let off throttle and/or half-clutch. Tires find traction, RPM drops, engine bogs, and well, you lose all the rythm for the next shift, and if the speed difference is too much, simply can't catch up, even if can only close the gap.Of course, that's because I'm very BAD at launching, so my opinion obviously doesn't count. Ha ha ha.But for purposes of drag racing, I'm in the opinion that a K20A is not very suitable due to the fact that most NA FWD drag cars has been traditionally high rpm small displacement machines, rather than cars with good low end torque but with poor middle to top end torque(i.e. B20 stock stroker)Even the turbo's realise this and utilize a two step for launching purposes.. But since the K20 supposedly solves this problem, it should be suitable, isn't it? but (based on reading Hytech's overview of the K20A oiling system)Due to the main issue of it's small oil pump, at high rpm past 8600, it cavitates and oil pressure drops. Since the VTEC is primarily oil fed, I leave that to the imagination of the forummers.But then again, there's the availability of the dry sump oiling system, which is used for most professional drag machines (close to 2G means the oil will really stick to the rear walls of the oil sump rather than close to the oil pump pickup)That could possibly solve the problem and make K20A a viable contender in the high rpm drag events.I still haven't looked at the innards of the K20 yet, except for the head, so I can only SPECULATE at the moment.But if talking about track cars, the K20A-R is king.And I also agree that gearing plays a part, because gearing plays with how wide or narrow the powerband needs to be, so have to select those that fit the powerband to be used.Then there's the length of the track as well. Imagine almost to the finish line in third, and suddenly you hit the rev limiter and had to release the throttle and watch as the guy without the rev-cut zoom by at the risk of blowing his engine. :P</blockquote>
