So...
Got the Brera Terracleaned yesterday.
To use a hifi analogy, first thing I noticed is the "noise floor" had dropped?
After the initial deep growl at startup the car seems quieter: that is...until you rev it.
Engine notes deeper, louder and it's growl sounds more powerful, noticably so.
Driving the thing; something that bothered me has been fixed just from getting the engine cleaned, and this alone is worth the cost of the clean.
At about 1000 rpm in first there was a hesitation and a judder before stepping up to 2nd. Progression through the revs is now smooth and rock solid now and the hesitation is gone.
Apparently this was a common issue with earlier pre 08 2.2 Brera's, so was a bit disappointed when my 08 plate facelift car seemed to have the same issue.
All gone after the Terraclean, seems it was the engine being a choked that was causing it, now sorted.
Car feels a lot more sprightly too, a lot more "shove" throughout the rev range and theres now a diesel torque style kick in the back when accellerating that wasn't really there before.
Driving feels more precise, revs stop and start in a way they didn't before and it drives a lot smoother, feels more powerful.
Goes down the road more than quick enough, point the car, press the pedal and it just...Goes.
Helluva lot of fun to drive, the improvement coming from a peachy engine working at it's best I guess.
Along with feeding it higher octane petrol, the Terracleaning has maybe given the car back more of it's "Alfa-ness".
The performance more matches it's looks now, which was the hope going into it so job's a good'un.
Thanks for the reccy Marco.
Wonder what a remap might bring to the table?
Probably not a huge increase in bhp, what I have is more than plenty, but if I can improve the driving experience in a similar way the Terracleaning has done, I'm all for it.
Some research required...
