Anyone else want a Fiesta ST Anti-Lag system?

Like the title asks, is there anyone else who would like an Anti-Lag setup for our cars?

Now before you throw things at me, I know that our Turbo spools up real quick because it's so tiny, but come on, admit it. You totally want that sweet sweet flame spewing goodness that everyone else gets.

It just crossed my mind because I know that a local guy that lives near me has one. (kicked my ass on a red light pull...)

I also began to look up what an Anti Lag system essentially is and what exactly it does. There are couple methods to achieve this and there are also a few risks added by using this. Unless you do some supporting mods and put a bit more money in the engine, you may run a higher risk of engine failure.

I was watching a few videos as well that really helped explain what it is and why it's used.
I myself would love to see an ALS made for our cars hopefully with options to add some supporting mods like a stronger exhaust manifold and some ways to try and cool the turbo down more. Probably those heatshield things I see on Supras and R34 at shows.

Just in case you don't know exactly how an Anti lag works or why it would be so great:
How a Turbo Charger works
What is Turbo Lag
Anti Lag system: "IGNITION DELAY"
Anti Lag system: "BYPASS VALVE"

Wikipedia link on Anti Lag Systems
Article from Rallycars.com explaining Anti Lag systems

I figure if we're gonna squeeze all the power we can out of this tiny little rocket we might as well go big or go home. Right?

Please what are you opinions?
Are you opposed to it, if so, Why?
Would we need more mods to help support it? IE: Exhaust manifold, different turbo, ECU tweak, wastegate change?

I made 354ft. Lbs of torque at 2950rpms on a stock turbo, that's not enough? Lol.

Sounds exciting, it is:)

But, we already have the flat foot shifting option which will help keep the turbo spooled and it costs nothing and weighs nothing.

The more stuff added the more maintenance and more to go wrong so things like this are far more applicable to race cars or cars seldom actually used, just tweaked and tweaked and talked about.....

If you wanted it more for blowing out a bit of flame when you shift that would be easy to do with just a little fuel injector in the exhaust, clutch switch taped into, on off switch easy to reach, simple controller...I was considering a flame thrower mod for my Studevette pro tour car build , just for the fun once in awhile, likely would not do it, just the thought was pretty fun:)

Awww, so no takers?

Maybe some day in the future.

Forged Pistons, reinforced exhaust manifold, better IC, ect. It'll be a hefty project but I suppose not this day. Maybe next year.

Cute picture:)

Not sure who would want to invest so much effort and cost into doing this with so little real gain for a street driven car or class rules for a race car. I have one of the most highly modded street/track FiST's and would not go there but it is really cool, just not enough need for it, would be fun of course to have it:)

This is way down on my list, but I want it as well. The research I found so, buying reinforced headers is a must. And you posted all the engineering explained videos. When I am finally ready to contact atp for a different turbo, I will ask about it, but this is years down the road.

Aside from the 'fun' aspect it would be pretty useless on the FiST OEM turbo. Get a ridiculously laggy turbo and there would be some function to it. Flames are fun though.

I want to upgrade to the deadhook GTX450R kit then do the anti lag, we are talking years though.

Real anti-lag systems reduce turbocharger lifespans to minutes.

If you are made of money, go for it.

What I want to do is borrow some partial hybrid alternator/starter/motor technology to make something like a KERS system to fill in some low end torque that I lose with a big turbo. That would not decrease engine life and I think a system might add less than 50lbs to the car.

The main problem is it takes a lot of engineering.

Well that is what I am going to school for and working with an electrical engineering student. And really? Minutes? After seeing builds on you tube that is a lot of money being thrown around.

It's been a while since I hopped in on the forum.

I also question the logic of minute lifespan turbos.

If it was the stock turbo and we have absolutely no groundwork of support for the system and yes, I could see it happening I suppose. Something melts/breaks, flies into the turbo and shit hits the turbine.
But like Klink said, there are setups that have money poured into them and they added anti lag measures so why don't we see or hear about them exploding their engines and turbos due to shitty engineering?

Also, why do rally cars have it then? They get thrashed like no other cars in competitions and they manage to do fine. I don't see them exploding their turbos all over the place.

Now do I claim to be an engineering genius? No, I do not. However, after going to school and seeing this stuff hands on, I am still determined to see this happen. I just don't have the resources to do it. If I was made of money like you said, me and DHM would be really good buddies right now.

I still stand by my notion of flames. I want flames shooting out the back of my Fiesta. (no I am not talking the way of the Pinto)

I'm on the same boat, I want flames and muscle car guys crying. Just the simpler things in life

The next question is making it switch on and off, I seen in rally cars, there is an anti lag switch, now every build I find that has anti lag shows the outside of the car (for obvious reasons). So is there a way to set it up as switchable on and off, to prevent wear to everything when is not needed. This is gonna be my daily still, don't need anti lag for every occasion

Race cars like GRC Fiestas have turbos that need a rebuild after one or two heats and their anti-lag systems are only on for a few seconds before the start, restarts and maybe hairpins.

Real anti-lag works by burning fuel in the exhaust manifold and some of it burns in the turbo. The temperatures are extremely high which is what makes the lifespan so short. The manifolds are probably Inconel and thick so they should last a while but the turbine won't last.

From what I remember (I'll have to rewatch the videos) you should be able to do a switch.
It will just take a bit of wire, some ingenuity, a switch of course, and knowledge of electrical systems.

I'll definitely be looking into it some more now and re-watching videos concerning it and how to make a switchable mode for it. Or maybe I am completely wrong and I need to go back to school again.

So after some research, I found that it can have a system where it is activated when the engine sets over a certain RPM. So it stays off while city driving, but for launches and hard driving, it will activate, seems like the best balance for maintenance while having Anti-lag, also contact whoever you are getting the turbos from (company wise) and inform them that you want to run an Anti-lag system. Some will change the internals and the manifold to handle the ALS better. It may cost a bit more, but not as much as a second turbo!
