Re: Steve's 3.0 24v supercharged GTV

Another small custom part, this photo shows the original Alfa 164 alternator mounting bracket modified by carefully positioning and welding some extra metalwork onto it. It now carries out the combined function of lower alternator mount to re-use the 164's much larger 120 Amp unit, the automatic bel...

Re: Steve's 3.0 24v supercharged GTV

Hi guys, Grdi - the transaxle is the 3.0 75 box as I understand that has the largest pinion of the variants sold in the UK. 1.8t was never imported officially to this country so I must admit I didn't bother trying to source one figuring the freight costs would be high for bringing something that hea...

Re: Steve's 3.0 24v supercharged GTV

Choosing to use the 7rib pulley for everything meant I needed to alter the belt routing. Mostly this wasn't too tricky, except that the water pump pulley and crank pulley are very close together such that I couldn't get two thicknesses of belt in the gap without them touching. I had Elite make a cus...

Re: Steve's 3.0 24v supercharged GTV

No factory Alfa's have exhaust manifolds that will fit a 24v motor into the rear drive chassis, you'll either have to make some from scratch, or modify a set of 24v manifolds to fit. I tried to modify a pair, but it turns out I'm not skilled enough to produce an airtight stainless weld! For a second...

Re: Steve's 3.0 24v supercharged GTV

Some more photo's of the bracket from above, plus the SC itself in situ. No complex CAD/CAM activities were harmed in the making of this bracket, this was just a combination of careful measuring, cardboard and thin board templates and some iterative work to get it in the right place. You might spot ...

Re: Steve's 3.0 24v supercharged GTV

Early on in the build I made a few decisions that influenced everything else: 1- Needed the layout to be as compact as possible as there is not much room in a GTV6 engine compartment, a 75 would be much easier to install. 2- Intended to use the Alfa 164 factory 7 rib poly-v auxiliary belt arrangemen...

Re: Steve's 3.0 24v supercharged GTV

For adequate cooling I had the GTV6 radiator re-cored as I've read they are rather oversized in the standard car. Howewer, not feeling the standard fans were up to the increased demands of water cooled chargecooler plus motor I used the more powerful and efficient twin fan arrangement from an Alfa 1...

Re: Steve's 3.0 24v supercharged GTV

The car runs about 7.5psi max boost, 50kpa over ambient on the MAP sensor, making 4 psi from 1000rpm tickover and the full half bar by 2000rpm onwards. Exact power and torque are as yet untested, once I'm happy with everything I aim to dyno this autumn and I'll post the result, calculations indicate...

Steve's 3.0 24v supercharged GTV

Prompted by a conversation with Kevin on Saturday at Alex Jupe's open day I thought I'd add some photo's and write up my own GTV6 conversion. I tend to visit this site often, but generally lurking rather than commenting - much like many others I'm sure. I've learned a lot from people and comments on...

Re: GTV 's at Alex Jupes 2014 and 2015 Open Day

Great to meet you too Kevin, along with Alex and the others. I'll start another thread with some info on my conversion. I've a few more photo's of Alex's event, as you said a good turnout and lots of interesting cars, with a significant emphasis on modified and non standard when compared to the turn...

Re: Great GTV display at Alex Jupes 2014 Open Day

Annoyingly I managed to miss last years event, which looked very interesting indeed.

I'll definitely be there with the GTV6 on Saturday (now up and running 24v and supercharged)

Re: Side exhaust in UK?

Yep it's perfectly legal in the UK, see here: http://www.youtube.com/watch?v=4iEai0_pdgM Had that on for several years, passed MOT's no problem as not too loud when ticking over. Also never stopped by police either as it was a "reasonably" sane sound when driving slowly or legal motorway c...
