Any views welcome on upgrading the 3.2 V6 on the Alfa GT.
Really looking to change exhaust and filter to improve flow and remap engine.
What figures are people getting on the rolling road before and after modification and any opinions on Alfa specialists like Angel Tuning, L&M, AH Motorsports, Autodelta.......
Will be getting this done shortly and post results of the equipment I've purchased and before and after figures.

Thanx in Anticipation

Hi there, Serb,

I made the following mods to my GT: Angel Tuning re-map, Novitec exhaust and BMC CDA kit.

Not entirely certain of the individual power gains attributable to each mod, (as I never had the car dyno'd before I did the work) but I'd estimate thus: exhaust (10bhp), remap (15bhp) and carbon induction kit (5-10bhp). Since it was all completed, the car has been dyno'd at 272bhp.

It changes the entire feel of the car (I also fitted uprated front discs and springs) - makes it feel like a more serious drivers car, with much improved throttle response and a fantastic sound!

Hey that's great 4 the quick reply.
I was thinking of using Angel.
I guess you had the exhaust fitted then the BMC CDA and then the remap.
Which springs did you opt for?

Thanx

Erm - you got me there! Your suggestion would have been the logical sequence but I in fact did the exhaust, remap then CDA. Ideally should have a new map to reflect the different breathing characteristics post CDA but in truth, Angel said it probably wouldn't make much difference and it seems to go just fine!

Re. springs, actually had Autodelta's coil-over spring/damper assemblies - cost rather more than a simple set of springs but I've made the mistake in the past of just stiffening/lowering a car with spring upgrade, then being unhappy with the handling. These are adjustable and having had a few fiddles, I think I've got a pretty good balance between ride quality and body control. Transformed the car, actually - the power is substantially more usable now.

Hey, finally got Alfa Nige to fit a CDA and remap the ECU on my GT 3.2 V6, also did a friend's 147 2.0TS during his visit. Much more torque in the mid-range and very lazy to drive, leave it in 6th thro' the City.
Going to have Koni FSD dampers fitted with Eibach springs to improve handling, altho' apart from the understeer, the motor handles very well.

I'd be interested in any gains in feel and/or actual recorded bhp on the same rolling road under the same conditions as the same car tested before the mods.

I don't believe for a moment that if you change the intake, exhaust, and have a remap, you can just add the individual bhp claims together, and I'd expect the remap to have the biggest single effect. Different filters/exhausts by themselves often drop bhp... Perhaps on the 240bhp 3.2 versions you can get the 10bhp back easily at the expense of the emissions.

I don't want too loud a sound for a car used every day and for business miles, but I'd like a bit more induction roar under full throttle and think the car could run a bit cleaner to the red line, so would consider a remap and intake kit at some stage. The standard mapping is so good in terms of driveability from below 1000 to 70000rpm and throttle response, I'd be worried about spoiling it in some ways...

I'm too thinking about a remap and possibly a ragazzon silencer but am a bit worried about a reduction in fuel economy (from remap) and dont want the exhaust noise too loud (from silencer). Anyone had these upgrades and if so what was the outcome? Also.. did you up the rev limiter? Mine hits the limiter about 500 RPM before the red line!
Thanks

I have had a GSR induction kit, Full supersprint exhaust and a remap and now have a dyno figure of 311.5bhp. the indution kit was still in the prototype stge and this gave about 13bhp over standard dont know how much the rest gave but would do intake, exhaust then have a map written for your mods.
PM me about the induction kit

If you want to hear the sound of the CDA kit under full throttle, go to 12 min into this movie It's my 156 with the 3.2+CDA on stock GTA exhaust. In everyday use, you dont hear any induction noise, it's only when you apply a heavy right foot. Dunno about added performance, but it does sound really good from the cabin too.

I've decided to go with chippeduk for my remap, but my stock exhaust still looks fine and sound's nice too,
would leaving the standard exhaust on rob me of valuable bhp ?
The car as an autodelta filter fitted,i'm just wondering because i could save some pennies.

So I've finally got Koni FSD dampers fitted with Eibach Springs over the original GT 3.2V6 damper/springs, fitted by Lyles of Newcastle (aka Italian Connection), supplied by Alfa Shop, and what a difference.
The understeer at low to moderate speeds has completely gone replaced by a confidence inspiring neutral handling.
The ride over bumps and pot holes at low speed is softer than the factory fitted damper/springs but when pushing the GT hard the ride really firms up, best of both worlds really.
I would really recommend this upgrade as I feel the factory fitted suspension doesn't really match the performance of the engine.
I used to want to belt the motor round long sweeping bends but instead would be fighting understeer.
The Koni FSD really perform, a soft ride on rubbishy pot hole marked sleeping policemen dominated British country roads but firm and accurate on long sweeping bends and carriageways.

whats the 0-100km/h on a remapped 3.2?
I've timed mine at a bit under 6 seconds but that was before I had the Scorpion exhaust done so I'd say a bit quicker now (but if not it sounds way way faster:lol:);) This was with myself and my dad (official timer) in the car and running on fumes:) I must say its the mid range that really impresses though not the pace from a standing start.

Hi, I had the same conversion - Koni FSD & Eibachs (plus Q2 diff) on my GT 3.2 V6, but since then am getting a groan on turning left or right. I was wondering if you have experienced any problems since your car was lowered?

Thanks, Graham Barlow
