GT cloverleaf technical q's
Couple of questions re: the set up on the cloverleaf GT diesel:
1) Sport button - I know this changes it to 170 BHP but exactly happens? does is do anything to the swirls? does it sharpen up throttle and the manifold and EGR work in the same way? Reason for asking is point 2.
2) Inlet manifold - my (limited) understanding is that the inlet manifold was uprated and is the plastic manifold that is on some of the other alfa models using the same engine unit e.g. 159s. I currently have an 06 GT which suffered swirl problems. to dispatch the problem and get the car running properly, I had a new manifold fitted - still the ally one but with uprated swirls and bar. As such, I have the "old" manifold lying in a box in the garage. I would very much like to have the manifold swirls removed on this unit, the holes blanked AND welded and then have this fitted to the cloverleaf, whilst retaining the operating arm for the swirls (connected electrically but the arm disconnected for the swirls).
First off, is this going to be possible (replace plastic manifold with ally). And, secondly, I assume the sport button wouldn't have done anything to the manifold swirl settings to create an issue e.g. eml lights or anything else untoward? What would be the practical implications? I assume there would be more power off the bat with having the swirls removed (i.e. more than 150 without sport button depressed) and then having the sport button depressed would give more than the 170 you would get with a normal manifold?
Do the clovers suffer with manifold problems? A bit of a pointless question because if point 2 is possible without any problems, I would probably have it done in any case!
3) Suspension - What is with the mass turn off with FSDs? My (again, limited) understanding led me to believe that the FSDs were/are **** hot but there appears to be a change in this thinking?
All responses gratefully received and Damien, I think you tried both suspension set ups (?) and that is why I look to you.
