pulley kit and other basic mods comparison

Ok guys. That's all and discussion is closed from my side. I have better things to do than killing my time in a forum.

Yo, @ichitaka05, do you want to lock this thread now?

Thank God. I feel dumber from even having participated.

No you don't. Otherwise you wouldn't have started this thread after saying the discussion was closed in the other thread(s).

I seriously tried to help you with this using real engineering practices to prove or disprove performance gains by pulleys, despite your rudeness. Its funny that you continue to avoid any discussion that could actually lead to a solution, but would rather be inflammatory in your posting. In fact, with your posts about needing certifications in the other thread you hijacked, I found it even more odd that you claimed to be more technically knowledgeable than at least 2 real engineers.

The fact that you have ignored every legitimate challenge to your claims as well as questions for clarification indicates really don't care about the discussion topic. It seems that what you do care about is the attention by posting topics that will get the most attention by people who attempt to increase the understand of the community. We all know what to call that type of person.

The "this topic is closed" comment is part of that behavior. Perhaps you will come back, perhaps you won't. I just wanted to let you know that I had some amount of respect for you at first, but that is now gone.

Nah... Don't. He will be back soon.

It has been done numerous times and not only about pulleys.

I remember similar debates when the same people were questioning about different air intake systems. They were insisting that there were zero gains even after real dyno evidence. Of course, no one from these people would accept the more obvious thing that a different air intake could provide REAL gains just because it was manipulating the MAF readings and you could have a leaner AFR. It is what it is with stubborn people. They'll never change ...

Have you ever done a really simplified energy analysis? In first gear of your car, (mine tops out at about 15 meters/second) about what is the ratio of energy required to spool the harmonic damper from 2000 RPM to 7500 RPM to that required to accelerate the whole vehicle?


Do that and then let's talk.

serious.
but that would imply that the dyno would show that your car really puts down 198hp at the wheels.
but since that won t be the case...
people will just tell you "we told you"

about the intake thing it s a bit out of topic here, and anyway it s pretty obvious as you said that the gains are because of a leaner afr since you are talking of an aftermarket intake with NOT scaled maf
if you like to go around with a untuned car with random afr just to gain few hp is your choice, once you scale well the mar for that intake you would realize that actually the gains are gone and the difference from the stock intake are so small that it s just wasted money for a NA setup. So well..people were right against you also in that case

My simplified analysis of this thread is waaaay too much energy is being wasted

No, the best option is to collect data in a way that allows you to average it out instead of basing it on (likely bad) assumptions.

You can't make two pulls at the same time and all that stuff you mentioned could change between pulls in the same direction, and you need at least 4-5 to be able to find any significant differences in the data once you've averaged out the discrepancies.

Energy is never wasted it is just redirected.

I think this thread is the exception.

Shorter gearing transmits more TORQUE to the pavement, not HP. If you're measuring HP correctly it eliminates this by factoring in total gear ratio.
