Antilag for drifting?

It's like anything. You don't NEED it, but it's a decent advantage if working right.

It's no surprise 99% of the top cars now either are big V8s or run nitrous as well as the turbo. And that's for one reason only, the instant massive response. Which is the sole reason for ALS.
 
I agree, but honestly, I think a small NOS shoot is a great solution and is not as hard as a proper ALS on the engine and turbo, and you can also choose when you spray, depending on your need. But it also put another system that could be an issue in the engine bay, so not a great solution from my point of view, but it allows for a bigger turbo to get more power in the top end and spray in the low revs to get it on full boost faster.
I plan on putting a supercharger on the LS if I need more power down the road!
 
The nitrous is a quick and easy solution, and deffo better than without it, but it's not as good simply as it does nothing aside from at 100% throttle; they're never regulated to spray more depending on throttle position.
With ALS at least you have the same throttle adjustability as you do with N/A or supercharged.
 
Oh, really thought it was also possible to spray on part throttle, but anyway, you're right, the ALS will give better results for the adjustability.
I would love to try a proper ALS on a drift car, should be interesting.
 
Personally I think a well set up ALS in drifting can only be a good thing. I have used ALS but its always been for show really. Problem with my car is getting air passed the throttle body's, so what we did was just wound the throttle cable up a bit and held the butterfly's open a little of throttle. Problem with this is you never have a good idle and you can't really run aggressive ALS. So now we have put a electric jacker on, and we can now run aggressive ALS. We are on the dyno next week to set up the ALS with 2 Settings, first will be for show just flames and noise but the second we are going to run really aggressive ALS. Will take some vids of the boost gauge to see the difference.
 
That guy is a fucking pimp man. Pony tail, mustache and a badass turbo E46.
Me like.
 
Fuck all to do with drifting. But this is what I'm talking about.

Bless you with your cute little Bee-R rev limiters, welcome to WW3

 
Here is the guy's latest video, from Round 3 of King of Europe in Spain. He broke a driveshaft in his first qualifying run, but he borrowed an almost stock M3 E46 in which he qualified 31st. He fixed his car overnight using some parts from Baggsy, and the next day he went on with clutch issues all day, but he managed to finish the race in 4th. At the end of the video there is his raw battle in the semifinal against Francesco Conti in the M3 E92 GT4. Next week he is competing in Greece, Thessaloniki!


 
Cock all to do with drifting, but a good video to show what properly working ALS can do.

Little 4cyl turbo engine pushing out 900bhp, ie ridiculously unresponsive normally.

Skip to 3min5sec for the rear view, as you can clearly hear the throttle position and see the response, and he spends fairly long periods off throttle. Absolutely instant V8 like response, can't even notice the thing come on boost, as it already is.

 
That above video is Pats 10000ft high altitude test and the first time pat has driven the car since its rebuild. Now has better performance and a new sequential gearbox with paddle shift. When we flew back from Finland i asked if he excited and he said no, he is shitting himeself and cant wait until the event is over haha. The car was 900hp before the rebuild, i have no idea what it is now or how much he looses at 10000ft. This car is far far beyond group b standards... far beyond!!
 
Fucking savage that car is, must be incredible to drive. Revs like a bike.

Big balls mannnnn.

a great example, with the blow off valve reacting under the antilag boost:


i think its a member on here too.

If the bov is working the anti lag isn't working properly.

If its running throttle bypass ALS there would be no vacumn post throttle to open the bov, and tbh even if he running egr ALS letting the air out of a bov instead of feeding it to the turbine goes totally against how to make it work properly.

I'm probably missing something here, but why is that? If the als has to maintain, say 0.3 bar off throttle and you close the throttle at full boost, say 1.3 bar, what happens to the extra 1 bar? I thought that the bov would let the extra pressure out until the als/ecu stops it at 0.3?

Don't forget, saying that is like saying what happens to the boost when you close the throttle and you haven't got a BOV. You don't stay on boost do you :)

The BOV don't let it out. It will go through the ALS valve, as that's part of how ALS works, it feeds air/boost to the turbine side.

Remember, BOVs are opened by vacumn, so it don't matter if the car is running 8000bar boost and the ALS is only capable of giving 0.1bar off throttle, if it don't get in to vac the BOV won't open.

No race cars running ALS have BOVs, as they do exactly what you don't want to have ALS that works well.

In some circumstances (you don't hear it on videos, but in the flesh you do) with ALS on you get an almost constant slight turbo chatter as the turbo is supplying more air than can be forced through the ALS valve. On my Cossie I could drive down the street slowly with the ALS on and it would be quietly chattering non stop for 30sec or whatever.

the unwanted air is used to keep the turbo spinning on an air bypass system like tibuc.

Imagine if you took out the dumpvalve and replaced it with a throttle body that is controlled by control unit. the throttle body is connected to the inlets after the main throttle body/bodies. This air goes through the engine, mixing with fuel on the way, and ignites in the manifold. Thus keeping the turbo spinning. The boost created is used to keep the turbo making more boost, ready for when the main throttle bosy is opened.

You need an ecu that can retard the ignition so far, when the main throttle is closed, that the air fuel mix doesnt ignite and also need to add fuel when the main throttle body is closed

no idea about the ALS stuff but thats not strictly true about BOV. Some are open naturally and closed by pressure then open again when you let off ( eg bailey one's which is why they are shit ). Others are closed normally and it's the sudden vacuum which opens them a la HKS which is better

so in theory a shit BOV could be slightly open which is counter productive to what you are saying ALS does in the same way you were saying you can get slight turbo chatter when using als for a similar reason ( not enough pressure escapes through the als valve so has to go somewhere. )

that may all be utter bollocks if i'm not understanding it correctly
