Exclamation "Wide Open Throttle shifting"

A buddy of mine taught me about "Wide Open Throttle shifting."
Now does this cause harm to the car and why would you say so. The reason why I am asking is because you are under constant boost through the whole way, but you are still depressing the clutch when you shift, so the clutch should be okay. Let me know your opinions, I am sure others are curious to know.
For those who do not understand what WOT Shifting is: Basically shifting at redline and not releasing your foot off the gas while you are shifting into the next gear.

Also called powershifting... I personally think its dumb, because as soon as you miss that shift, bye bye engine.

Hah, yeah, we know...it's called No-Lift Shifting (NLTS). I've shown a few in-car vids recently of me doing this at the drag strip. IT can damage your synchros, or if you miss the shift, you could overrev and cause problems.

It's not recommended for most people, especially not on the stock clutch. It's also not easy.

theres a thing called a rev-limiter . your engine will be fine if you miss shift, but the problem is the transmission takes a beating when you do this, and espically if you miss a gear it hurts even more.

helps improve times tho

people have different terms for the same thing. Powershifting, NLTS, WOT shifting are one in the same.

Yes the transmission gets damaged... no matter how well you can do it. You are slamming into the synchro's at the highest level possible. Think of the synchos like a braking system for the tranny. They are designed to match the trans speed with the engine speed. When you hammer the car into the next gear those synchos get severly wacked. Now think of what the poor clutch has to try to hold on to. 9k rpm dump into 3rd or 4th gear.... yeah its gonna slip. Now, just imagine the shockwave going through the transmission when you drop the clutch into the next gear... the engine is trying to spin it at 9k but the road speed is 4k rpms slower... its a big bang.

Missing shifts wont do anything bad (Unless you hit a lower gear instead of the higher one... like hitting 3rd instead of 5th or 1st instead of 3rd). The rev limiter should be in a place where the motor can easily rev in that area.

It will make your car much faster. It is not difficult at all.... you hold the gas down and pound the shifter into the next gear. It is extremely easy. Yes it damages lots of parts on the car.

I know the rev limiter doesn't stop the engine from a 'mechanical' over rev. Such as going from 3rd to 2nd instead of 3rd to 4th. It will however stop you from going to high while in a gear and under load. But would stop the engine from spinning with the clutch depressed or while in neutral like when 'powershifting'?

NLTS

On Wednesday, I'll be at the drag strip all day with pretty much unlimited runs, so I'm going to both try to hit good times and do many camera angles. I want to point the camera at an angle so that you can see my feet and my shifting at the same time.

For ***** and giggles, I'm also going to point the camera backwards to watch my opponents fade away, haha.

Yes... it cuts ignition and/or fuel at a certain RPM. It doesnt care if the clutch is in or out.

Quite the opposite, imo. It's very difficult to make a powershift at high rpm unless you have a good clutch combo. I could only do the 3-4 with my stocker and with my ACT, but now with the Exedy, I can do every gear with ease and no fear of ever missing a shift.

Well than it wasn't "hard" your hardware just couldnt do it There is a big difference.

I used to powershift with my ACT through every gear (Hence the reason I burnt it up so fast). I powershifted with the stock clutch the one day I had it at the track. I power shift with my current clutch. Some cars I have been in dont work very well... but then it isnt difficult to do it... the car just couldnt.
