95 TT turbo question

[FST4RD]

Drove my TT SW down to Dunedin on Friday, driving round the hills I could hear the turbo spooling up extra loud. Normally I can just hear them spooling up, this was much louder. Although they still boosted right up properly and there was no smoke. Drove the car back to Chch today and no odd noises.

Going to check them out, ie take the intake pipes off and give them a wiggle to see if they are slogged out or anything.

Anyone had this before?

Also I'm not after power, car's fast enough as is. (fully factory).

Want I want to know is fuel economy wise and reliability which is best, single turbo conversion, twins in series, twins in parrellel?

Car has just turned over 170k's so I was thinking that if the turbo was on it's way out I might pop them off and get them recond.

when you was driving was it at night? i found my spool noise quite loud when at night on an open road.

as for fuel economy. to save some gas just lift off the pedal a bit.

my single turbo bg5 guzzled the gas but it has the wrong ecu at the moment.

someone that has done the conversion will know tho.

There and back I managed to get 9L per 100k's which I thought was pretty good.

One thing I do like about the twin turbo is when the second turbo kicks in and the boost gauge shoots up from 10psi to 15psi.

There are some pretty steep hills in Dunedin so it could have been that.

Other thing was that water from the washer bottle kept on spraying up onto the back window going up hills? Not sure what this is all about?
