ALS on MS

[worldhazard]

Got this crazy idea in my head while @ work today. Using MS, can you make an ALS (anti-lag) setup? Consider running via stock gtx setup theoretically...

I've done a little diggin but anyone who asks about it on most forums gets super flamed. It's not the best for you turbo and it would be pointless on a VJ-20. There was an old MS version out there that had a crapy anti-lag but it's old and for real als you really need to get air right into the exhaust mani.

Pic is way to big...

That+a bunch of fuel+a crap load of time retard=boom in that manifold.

The best ALS systems can keep maybe 5 psi between gears, but that for WRC teams that have a restriction to breath thought and can afford a new turbo every race.

Ya well attempt to flame away lol. It serves the purpose if done correctly in motorsports (rally) application which is where my research is going. No doubt it's bad for the turbo. The goal would have some extra turbo's lying around to swap out for when they do go boom.

Curious why it would be pointless for the vj-20..? I'm lookin at the subaru turbo swaps more for a serious application.

If you want a flame just hook you the flat shift mod. Anti-lag is for turbo's that lag... I like with a restoration or big turbo. The VJ-20 has just about 0 lag between gears. Something the T4 that I'm running doesn't even have that much when you shift.

when it comes down to the turbo itself, i'll be looking into what combo eventually, but right now it's only research really... And.. i'm not looking for a 'flame' lol... i can just throw a spark plug back there. Depending on a setup, and the size of the turbo... ALS could be beneficial.

note: this was only a crazy idea that popped up completely randomly today. Who knows if it would be an honest pursuit

[worldhazard]

so... can someone explain this 'flatshift mod' thing? it is a megasqurit thing too right? from some reading and youtube vids, you can apparently keep the accelerater down while shifter (with clutch still?) and the cpu holds the revs at where you have it set, and continue going... you just don't drops revs while shifting...?

is this only while the accellerator is pressed, so you can still downshift like normal?

Flat foot shifting is a way of cutting spark to the engine during gear shifts. Your foot is on the gas 100%, even during shifts. You still push in the clutch and shift normally. The purpose of this mod is not to lose time by coming off/on the gas during shifts.

Yup time or boost. I have mine set up on a clutch switch. Push the clutch down, cut spark, shift, clutch out rev limit goes back up.

VJ20 doesn't need antilag. VJ23 could use it, as could even a gt28r. But vj20 and the like aren't moving enough air to see any gains, and thus aren't losing enough flow to justify it.
