Is it possible to buy off the shelf some system to remove turbo lag. I've heard of an EVO that has an anti-lag system that keeps the turbo spinning between gear changes. I'm more curious than anything. Any info good/bad would be appreciated.

Please keep any info spelt out very clearly. I'm certianly not the most technical of people!

 

In a nutshell yes....

However it will cost you lots of money & eat your turbo

So unless you can live with thatjust rev it a bit more in each gear so you don't come off boost between gear changes

 

So there's the carrot! Thanks for that. Any idea how much and where you find such a system? Web links would be good?

 

Talk to G-Force Motorsport in Aylesbury, but bank on the odd new turbo ...

 

Shame it is such a destructive bit of kit. Love the idea of it. Thanks for the help.

 

Like C says it will eat your turbo mate and wreck it. However it will make all manner of sounds, pops and crackles and sound pretty good, might get a few flames also.

 

The rally car day last year at Castle Combe had some anti-lagg ecu tuners..

Go along and ask them what's the pro's and con's

(I have heard it kills the turbo)

 

Yep they sound great as well but your turbo will glow cherry red

 

just buy a gems ecu and u get anti lag free

 

Any free turbo's with that sir ?

 

With a GEMS The mapper can adjust how fierce the Anti lag is and its based on a on off switch so you decide when you want anti lag.

 

Same with motec

You can adjust the anti lag so it doesnt eat the turbo to much

 

Depends on the system, but for everyday driving it won't really help.

Anti lag is to keep the turbo spinning while you are off the throttle, so when you come back on you have instant response. What it doesn't do is keep the turbo spinning while allowing you 15psi boost while you are pootling around at 1500rpm. the main reason is the system normally screws with ignition timing so you ignite the inlet change as it exits the exhaust ports, rather than in the cylinder. Great for turbo spinning, not great for normal power.

If set up properly, it should have a time limit so it's not on for ages at a time, 4 seconds should be enough (4 seconds continuously on). It puts great strain on the exhaust valves, exhaust manifold, and the turbo exhaust housing. But used in moderation it can be useful.

The EVO system also has an auxilary air feed to the exhaust manifold, but it's only a token effort, and not enough for full on ALS. The WRC cars use a vacuum operated valve to feed fresh air into the manifold, this lowers the temperature of the ex gas while maintaining high gas speed.

givn the right model off turbo, some just remove the D/V to aid lag

 

Thanks for the effort... far too technical for me!!
