End of an Era...Which Gearbox/LSD combo

well said Ratty

at last, yes your S with the ATTS deleted will in effect be the same as the A8 which is faster as it is not dragging round the weight of the humongous ATTS

and charged aswell

holy hell

Yes do it mate, I'm removing a type s engine atm and the atts is a pain in the ass to work around. I wanted to swap it for a lsd box but not allowed lol

Will the passenger driveshaft be ok? I'm not sure the bolts for the carrier will fit anymore?

How much are the Greddys usually?

Pete the conversion plates are Comming from the US. Then all I need s a standard passenger driveshaft and it has to be modified very clightly to clear something. Very easy to do....apparently.

Then you just slap on your choose of box lsd.

Greddy ecu are usually around £450 plus £150 for the boomslang plug and play harness.
I'll be selling my combo for £360 when I get round to it.

What bhp was your car running before you started the huge overhaul of supercharging? See. I'm not fussed about going so far. 250ish bhp would be more than enough for me. I'm just guessing I'd need a Greddy ecu to support any further minor performance mods I did.

Well opinions and arseholes and each to their own of course.

Now that it is at least finished and running, is it not worth at least getting it tuned to see how you get on with it like that and have a bit of fun with the car while you buy all the other bits before you take it apart again?

You might find it is actually tuned/powerful enough for you after all?

Sorry to hear about all the problems

Would be a bit of a shame to ditch the ATTS in persuit of a bit more power. What kind of power are you looking at once the supercharger is up and running? Is that gonna be significantly more than you have already?

I guess you have already weighed up these questions and that's why you are going down the route you have chosen. I am thinking that an Lsd equipped Lude won't be significantly slower round the bends than ATTS?

Also interested in your Greddy Emanage when you sell up

Oh, and the ATTS badge too

The problem the supercharging and turbo charging is the amount if fuel cut or boost and or ignition timing you use. Too much forced induction on piggybacking tunning on an na ecu will cause the stock ecu to fight the piggyback and cause the tune to drift and loose power. On an na setup it will work fine or on a car that us already turboed ecu.

My tuner basically said he wouldn't guarantee the tune would stay and I'd loose £400 spent on the tune.
For my application standalone will be better.

Before the supercharger I was at 227bhp ish untunned. Add a euro r intake manifold and a greddy tune is hit 240-250 ish. But the supercharger should be taking it closer to 300. This is all flywheel power not wheel power. I'd be happy with 250whp.
