the gt series is rated to handle 950 degrees, which means they should handle mild antilag, but you will eventually get above 950 degrees.
What power figures are you looking at?
ihi wrc turbos are up for the job, but the cost is ridicoulus.
Also aggressive als will put all affected parts under such restraints that they will need short overhaul intervals, which again is causing ridicolous expenses, and then again.... ITS NOT WORTH IT!
unless you are entering some sort of competition.

and how quickly do the temps rise?
i'm estimating 3secs of full throttle ALS for boost to rise then normal engine running for the run?

ahh so you are just going to use it as a launch control?
dont use als then.
You dont need launch controll or als to achieve full boost on start.
When i launched with my 4x4 i held the handbrake, revved the engine and let the clutch far enough out for the driveline to be tensioned and the boost to build up to 1.2bar.
uses some clutch though and wont work on a sinter setup.
not shure if the launch controll will let you build boost as there is not enough resistance in the engine only when revving, but it will allow you to just keep the throttle floored, not thinking of kepping the revs at a certain speed.

cant you buy a launch controller for 80 quid?Im very interested in them as all they do is just hold the revs and allow the boost to come on, clever and cheap but i forgot who and where make them
any ideas??

Lee you'll probably need to look at a custom spec. It'll want a marram shaft thats for sure but the old t4's wont flow as much as 35r, quite possible the t4 will flow close to a .86 30r.
ALS has got bad news written all over it imo
Just set the launch control nice n high and dump the clutch.....i'm sure the txb will be fine

Ask yourself this....
Do I have enough traction ( and a strong enough drivetrain ) to launch at full boost, circa 5000rpm ????
If you do...Im already impressed !!!!
Unless you have huge amounts of traction, you dont need to launch with a lot of boost.
A mate T34 Cossie can launch WOT at a tad under 5000rpm, and really get off the line. No bogging, and no massive wheelspin ( not that it would have enough power to anyway ). It only makes about 2-3psi doing this, but it works very well every time.. No ALS, just an auxiliary rev limit.
You dont need ALS to get off the line well.

first off all, you wont get any ALS function with the throttle full open, it only kicks in when throttle is closed a certain amount(tuned in). On my GrpA escos it kicks in below 65% throttle and has different amount of ign retard through the revtable, the lower revs go the more retard to keep turbo running. I have not seen any rallycar having full boost on ALS, it usually just keeps the turbo rolling so when throttle is applied it boosts up immediately. You could propably go full boost, but there is no meaning cause the car needs to decrease speed when throttle is closed, else you will either burn brakes, turbo or both.
WRC IHI turbo is too small even without restrictor to flow more than ~400bhp its made to be optimum for 360bhp. Those cost LOTS and repairs cost almost half of the turbo, same thing as GTs you need to replace the core when bearings run out.
Only MarM 247(superalloy) shafts can take the abuse of full ALS what i know, used in GrpA t34s for ex.
You need launch control as the gentlemen here adviced you about, even latest WRC cars use it.
Regards

I bought the launch-control from demon tweeks, tried both micro-dynamics and omex, kost about 90quid
Works PERFECT, nothing else to say.
Works like an custom rev-limiter, nothing to do with als, and is an WOT-system.
Launched at 6500rpm, held the throttle at about 2-3sec and gave me about 0,7bar off boost.
RECOMANDABLE

Look in the rev limiter pages, its built in to most of them, as all it is is an second, lower, rev limiter
6500 isnt too high on a 4wd.
But on a 2wd boost on the startline makes launches even worse unless you got MEGA grip, trust me, i could launch in 2nd n still go nowhere at all by using ALS on the startline.
But if you got the grip, 2wd or 4wd, 6500 could be way too low, its all about grip.

with launch control you will have your foot to the floor.
higher the rpm and longer it is bouncing off the rev limiter the higher the boost will raise.
its eaisly possible to get full boost like that if you wanted.
and it sounds like bouncing off the rev limiter does, but at a lower revs, so papapapapapaapapapapapbangpapapapapabangbang etc etc.

depends what turbo, but set fairly high revs on the launch controller and keep your foot planted while using it for 10secs or so should do it.
and then watch the car just sit there doing a burnout (or break the rear diff
), as it sure wont grip!

so what is safe boost for launch then a stage one cossie. I have 8x18inch Goodyear F1's at the back which should help a bit
