A while back I posted this thread
asking for opinions/information about some mods I was considering for my car.
I've had all the work done now so I thought I'd give some feedback on how it all went and the results.
(TL;DR version for the attention span challenged: Q2 good; GTA clutch good; unsilenced Ragazzon: loud, but good
My car was due a cambelt service/waterpump and I'd decided to get a Q2 fitted while it was in, but due to budget considerations I wasn't sure whether I could afford to go for the GTA clutch/156 flywheel upgrade as well. However, Alfatecnico gave me a good price for doing the whole lot together so it went in a few weeks ago.
I'll just get straight to the point: this is probably the best single upgrade you can do to a GTV imho. It completely transforms the cornering capabilities of the car, reducing understeer enormously and enabling significantly higher cornering speed. Whereas before throwing the car into a corner too fast it would just start to wash wide, meaning you had to start adding more lock or (if you're brave) lift off mid-corner, now it just digs in and hauls the car around the bend. The only downside is that it really shows up how bad the lateral support in the seats is as you get thrown around
Having a CG-Lock
on the seatbelt improves things quite a lot, but not quite enough to stop my bum sliding across the seat.
GTA Clutch/156 solid flywheel
Good thing I decided to do this as the original clutch was about at the end of its life. With the lighter flywheel the engine revs more freely now. The combination of uprated clutch and single mass flywheel means the clutch uptake is not as smooth as it used to be - there's a little bit of judder if the revs aren't quite high enough - but overall it feels a bit more positive and better able to get the power down during fast starts (not that I would participate in anything as uncouth as a traffic light grand prix
After the car had been to Alfatecnico it went off to the body shop to have the bumper modified to accept the quad-pipe exhaust. They did a great job - cutting out a new recess, plastic welding in a supporting lip and repainting the bottom half of the bumper. Unfortunately the paint on the bumper has faded slightly, so there's a mis-match in the reds, but I didn't have the budget to get the whole thing resprayed.
Ah yes, this didn't quite go to plan. I originally planned to get the centre section with a small silencer
and the quad DTM-style un-silenced rear section
. However, due to severe brain malfunction I decided this setup would probably be too quiet and I ordered the un-silenced centre section
Got the order confirmation back from Alfisti quickly and all appeared to be going well. Then the next day I had an email saying that there had been an error in their stock management system and the quad DTM wasn't in stock and would take 1-2 weeks to get in from Italy. However, if I'd prefer they could send me the standard 70mm quad rear section
instead as this was in stock. I declined and said I'd wait.
Fast forward two weeks...
I emailed Alfisti to see how it was going and they replied saying they were still waiting to hear from Ragazzon and it would probably be another two weeks. In the meantime I'd been wondering whether the DTM was the right way to go. They look great with the Autodelta rear aprons, but on a standard bumper I was having doubts. So I decided to take Alfisti up on their offer to send the standard quad version instead, which turned up two days later
Had the exhaust fitted last Friday, so it's only been on the car for a week and needs to soot-up properly to get the proper tone. However, there's one things I'll say about it: it's loud. Very loud. Some would even say obnoxiously loud and I'd be hard pressed to disagree. It's worse when it's cold - it's louder and the tone is more harsh. Once is heated up the tone softens and it gets very slightly quieter. But the sound is to die for
snarly and growly at lower revs building up to a wail at higher revs. Lots of popping and crackling on the over-run too. Sounds like a proper performance car now - just need to see if it shoots flames out the back now
Not sure how suitable it is for a daily car though. As I'm a gentleman of leisure at the moment it's not too much of an issue, but I have spent the past week commuting in heavy traffic to attend a training course and it was a bit anti-social
But cruising at 70-80 on the motorway it was perfectly civilised - just a moderate background growl.
I had the first chance last night to give it a proper outing on the A38 and it was just glorious. As much as the sensible part of me thinks that fitting a silencer would be a good idea, it would be such a crime to bottle up that sound again...
