as for not feeling the effects Steve on a loose surface, you have never driven through a forrest at competetive speeds so .....................
for you 
it does make a hell of a differance in the forrest, makes the car alot more predictable on the loose, funnily due to the lack of lag
the noise and the heat are definatly the downsides, the heat build up under the bonnet takes some serious managment to keep control of it so i found. and the noise, well we all know about that
its banned on most single venue events for the type thats the norm on cossies due to the excessive noise/backfiring created, but for the forrests, there is no better sounds than listsneing to a rally car on full chat with als on in the woods
i should do more spectating rather than driving !

I already possibly have a great turbo for the job, the T34, but not if I cant use it anywhere, failing that i will have to find a GT series turbo that spools up as quick as an anti lagged T series

spools up as quick as something thats already spooled is a pretty tall order.
even more so at 200bhp per litre!

Chip is bob on, no turbo will have the same effect as properly effective ALS.
It dont even feel like a turbo car, its the part throttle stuff more than just no lag at full throttle, the throttle control is off the charts.

I've driven Escos equipped with race spec T4 and very agressive ALS - boost 2.2 bar held, 1.7 bar off the throttle on ALS, INCREDIBLE FEEL. I was just sliding all the time taking advantege of 3 uprated diffs and LOL'ing all the time. Engine response, sounds and the way you can extract yourself from tight corner is simply amazing. I would love to have ALS even on my way to university

And the noise it makes
- some people said after my test drive "it sounded like there was some distant battle in the woods"

Mike Rainbird you surely kow what you talk about but lok at the situation when you brake for corner for very long time let's say it's an haipin or something tight and you shift down all the way to 2nd or even 1st and then you step on it during exit, won't you have problem with lag then? Even my small turbo has....while ALS'ed car will just shoot forward....

.Seems most ALS'd T4 cars just have less lag, rather than the "real" ALS feeling.
Barring that one Arazel has driven
With a .48 T34 its silly, can stay off throttle for ages and the boost gauge is still showing 27psi

. Also as it will be no more effective on a .48 I may aswell keep the .63... - I wont be feeling any lag when switched on anyway, right?
This just means I need to know about Intake air temps while running ALS, will an RS500 style cooler will do what I need or are there still going to be temp issues?
A post turbo water radiater is a must in my eyes for the safety of the rest of the engine too.
DAMO, POST SOME STATS UP FOR US PLEASE AND PROVE? DISPROVE ALS ON A CIRCUIT/TIMED LAP
