150BHP NOS on SL55

[James Taylor]

I was looking to add Nos to SL55, looking to have it installed by Wizards of Nos.
Has anyone heard of it been installed to SL55?
Does anyone know of any negative sides to installing it, would only be used on road very infrequently?

A mate had over 250hp increase through this on his RS6 a few yrs ago. They do a good job but it wont be cheap. I've also done it on an old GSI Vectra, that ended up destroying a piston and head and block... you get the idea.
Just make sure its well setup with some safety features built in to stop Nos running without fuel etc etc.

Was the Gsi setup by wizards of nos?

No - it was set up on the dyno though, the issue was the stock non FI pistons which gave up when it got hot. Yr has FI forged pistons standard so it wont be an issue so long as the fueling is good.
