Finally pt2! That sounds bloody awesome! 1.3bar at 1800, picks up really well! 😎👍
Goddamn, sounds like a war in there! Also im pleasently surprised about the temp drop. Thanks for sharing!
I don't think enough people realize how big of a deal this is. How many people have this up and running, because I cant find many.
absolutely. imagine all the potential powerband your car has in it, and start that from 1500 rpm and have it continue until you run out of springs/valves/crank lets go
Theres alot of Rally and RallyX Cars running this, but they don't really get shown
@@WaltonMotorsport where you taking the vacuum to put on the anti lag valve please the only question I want you to help me out
Sounds like A high revving bike as f**k N/A inline 4! insane! Need this on my 2jz swap E90.
I'm also working on a ZF 8 hp gearbox and ford 8.8 rear end conversion. All while maintaining an electric 12V air-con system, and keeping a lot of the interiors and sound-proofing.
This sounds similar to the prodrive "rocket" anti-lag used for WRC.
That method with the bomb worked well on Subarus due to their manifold design, however on traditional setups this methos is favoured due to reliabilty and ease of manufactuer.
@@WaltonMotorsport I think they achieve better anti-lag by designing a rocket nozzle fed by the fresh air bypass, that pointed rocket thrust directly at turbo inlet, thus spooling harder and faster. Sure the manifold layout is different but, still possible on other configs.
Walton Motorsport you can do rocket anti lag on any engine configuration.
Basically it is the same system
So badass🔥🔥🔥
bit late but did you ever get to work out how to get it to build boost statically? also i notice now turbosmart makes an eletronic version of the antilag valve, any experience with it yet?
craaazyy niceee
Dope
Hia lads, I’m currently in the process of building my big turbo r56 mini and I’ve got a tubular manifold I’ve already purchased, if I ordered one of these valves would I be able to send it to you guys with the manifold and have it plumbed in the same as you did in the previous video? And if so how much would it be please if I supplied the ALV40 :)
Hey, i guess im a bit late but these are the best videos of fresh air antilag ive found.... so question what ignition angle are you using and how much more additional fuel? I have a antilag project in process and sofar im just getting one loud pop and then its not spooling the turbo and my guess my ignition and fuel enrichment perentage or off.
We only make the hardware and leave the tuning to professionals so Im not able to answer those questions I am afraid.
@@WaltonMotorsport okey thanks though? Do you have contact information to someone we would be abbe to ask though
@@maikelniessen6621 if you need to ask it's not wise you do it yourself. Anti lag usually requires aggressive ignition timing and if not careful you can damage your engine.
Can this type of valve installation be installed in a standard car?
Can you make a flange adapter for the is38 direct mount so we can plumb the FA ati-lag?
Great 2 part about fresh air antilag, will be interested to see how you get on with tuning it to make boost at low rpm/idle. A couple of questions if I may -
1. I assuming you need some positive boost in the charge pipes before the cycle can start? Is there anything preventing manifold pressure entering the charge pipes if there is a lack of pressure and the ecu requests the valve to open?
2. Is the hot manifold the only ignition source or are you still retarding timing? I'm a way off doing this myself and have noticed my VEMS ecu allows 100% ignition cut when ALS is active
Thanks! Andy
So are we, we havent managed to get back to this project as of yet.
1. Sort of, to get around that issue we have the boost feed into the accumualtor tank via a non return valve. This is the pressure source we use for actually controlling the vavle. So you need generate a little boost before you can operate the valve. (a single rev is enough)
2. Not 100% sure, I will let you know If I can find out from the Tuner.
@@WaltonMotorsport thanks, really appreciate the reply. As I get further into my own setup I might have a few more questions, hope you don't mind!
Do you mean is there anything preventing the valve from acting as an EGR valve if it's commanded open and there is insufficient pressure in the inlet tract to overcome exhaust manifold pressure? That's how I read the question, anyway. The valve only activates on closed throttle, so exhaust manifold pressure (EMAP) at the activation time should be minimal, and if the valve opens quickly enough residual pressure in the inlet tract would easily overcome any exhaust manifold pressure. Once the system starts flowing it is self-perpetuating as the turbo is increasing the inlet pressure by virtue of the increasing EMAP spooling the turbo up.
As for ignition - I haven't set one of these up myself (yet!) but all information from Turbosmart, HP Academy, and other sources that I've seen says yes you still retard ignition timing.
I also notice that Turbosmart now offer a 6-outlet flange themselves, as well as an Electronic version of the valve which does away with the need for a pressure/vacuum source to actuate it. I did find your use of the pressure accumulation tank very interesting, though. For my own implementation I was going to simply utilise an electric vacuum pump as found on many modern engines. I'm also tossing up between the 6 individual pipes placing the air as close to the exhaust port as possible to get the best combustion (as per Turbosmart recommendations) or a single "rocket nozzle" style outlet in the centre of a 6-runner collector directing the stream directly into the turbo flange.
@@russell6167 I'm thinking if you're sat at idle and open the valve. I guess if parameters are set for say 0% tps and min 2000rpm then there should always be more pressure in the charge pipes than exhaust? Should mean that MAP vacuum should be sufficient to open the valve too.
i saw on a different video somewhere where they used a vacuum generator (?) off of a bmw to allow for vacuum to be utilized by the brake booster, is this something you guys have already worked around? i cant remember for the life of me where i saw mention of it; it could have been robert thorne's video on their rocket anti-lag on their S2K but i cant recall at the moment
Yes theres quite a few methods, alot of RX cars just use a 12v pump, We went down this method as its the simplest and easiest to fix trackside (in our opinion)
@@WaltonMotorsport awesome, thank you for the response
im gonna do this to my 2jz for sure
Did you get any further along with this?
the strategy in the ecu is the same as that used for the traditional als with the only difference that the throttle remains closed?
👀
Are you still running a bov? @walton motorsport
No, its blanked off with the Turbosmart part
if this shoot a fresh air into the turbine why that still pop out the fire.?
Its because we are not using the air to spool the turbo, we are adding the air plus fuel to create combustion in the manifold rather than the engine cylinders. This combustion is what spools the turbo and as a result creates flames.
@@WaltonMotorsport oww,,ok i understand..tq for explanation..
