1982 GTV renovation

[Anth73]

A few more engine bay photos. Dyno tuning throughout next week at Melbourne Performance Centre to finalise the Motec setup in a variety of cold and hot start / running conditions. Aiming for at least 180hp at the wheels and a nice strong torque curve.

Short video in the comments of the car being driven for the first time since Jan '21. Very happy with the sound!

Dyno tuning has started!

Engine bay looks awesome!
Will we get to see [& hear] her in the flesh at Spettacolo next weekend?

Well the dyno numbers are in and I'm very happy with the results for a build that targeted a fast road setup with usable power/torque. Dyno number are 125kW / 230Nm at the wheels (not sure why 190Nm is quoted as the max torque), so perhaps 150kW or a little more if you believe the 18% driveline losses typically quoted for a GTV6. Every dyno is different so who knows what it may actually be. About on par for a warm 3L 12V given the SZ was quoted at 154kW.

The power and torque curves are really nice though, good torquey midrange with sustained top end power to 7400rpm.

Back to Rankins Panels for final fitting of the new bonnet and hatch, a couple of minor things to tidy up with Monza Motors and then off to Spetaccolo on Sunday to mark the end of a 22 month journey.

Nice one.  Solid numbers.  Would have been nice to achieve your aim of 180hp atw, but for a street car, the numbers are a bit academic when you're not driving on the rev limit very much.

Pity I can't make Spettacolo!

Some interesting feedback regarding the flat power numbers from 6400rpm, suggesting a lack of airflow. I opted not to enlarge the plenum throats and intake runners despite these being pointed out in Jim K's book as being inadequate for a tuned 3L. Looks like I've got a date with some flapper wheels in the future.

Great to see it up and running! Well done on a big achievement.

Like you, I suspect there might be a little more to be had at the higher end if you can get it to flow better.

I'm also surprised to see peak torque at so high an RPM but I'm no expert. The SZ had peak power at 6200 and peak torque at 4500 but that was running Motronic with AFM. Did RJ give you an idea of curve characteristics of his camshafts? And if so, does what you have match?

[Anth73]

I went with C&B "road max" cams. Though the torque peak is higher in the rpm range, 90% is available from 3000rpm. Hopefully that translates to a good midrange. The engine is still quite new also, expect it to loosen up over the first 1000km.

Christmas came a month early with the present being a 3lt busso to drive home. I'm still smiling from the experience! See you at Spettacolo on Sunday.

Some pics from early morning at Sunday's Spettacolo. It was a great turnout with plenty of 116 Series cars on display. My GTV6 conversion attracted plenty of onlookers once I felt comfortable leaving the bonnet open despite the threatening grey clouds.

Well done to all who came along and to the organising committee. There were so may well presented Alfas it would have been a challenge to pick the Show 'n' Shine winner.

Thought I'd provide an update after a month or so of getting my GTV back on the road. As you'd expect there were a couple of minor teething problems to resolve. Firstly, on the drive home from Spettacolo I noticed a trickle of water on the footrest and realised we'd forgotten to connect an AC drain hose to the back of the evaporator box. My GTV wasn't an AC equipped car originally, so it lacked the hose and the pressing in the floorpan was still blocked off. Thankfully Monza Motors had a spare AC drain hose. Secondly and more seriously, I had power steering fluid on the garage floor. After getting the car towed back to Monza Motors they diagnosed the leak was caused by a poor fitting clamp on the power steering hose near the pump. The rack and pump were both okay.

Also annoyingly the reconditioned 120A alternator I fitted isn't charging sufficiently at low rpm, causing the battery warning light to glow for the first few minutes of driving. We had to fit a slightly larger diameter pulley so the alternator drive belt would clear the crank angle sensor but it should not have made too much difference to the alternator charging. We'll look at that at the 1,000km service. One last niggle is a slight driveline vibration caused by the front donut cage. The tailshaft was balanced however not with the donut cage fitted...there's a trap for the unitiated!

I also had Santa deliver a couple of very nice NOS parts. The odometer on my speedo wasn't working and the speedo itself always read 10-15kmh too low. I managed to find a NOS GTV6 speedo with "00008" on the odometer. The parts label on the original factory packaging has a date of 14/02/85 so I have no concerns about its authenticity. I'll also know exactly how many kms my newly built 3Lt V6 has travelled other than 200km or so going to/from Monza Motors and to Spettacolo. It also reads within 4kmh of my GPS speedo I was using as a backup.

I also decided not to fit a radio and instead sourced a NOS GTV6 blanking plate with the original parts label and packaging dated 30/03/94. I'll fit a bluetooth receiver hidden under the dash, amplifier in the boot and speakers in the rear door cards as per factory fitting.

Overall I'm really enjoying the V6's extra torque over the twin spark previously fitted and the noise from the 3Lt is an absolute delight!

Thanks to Mick Aarons I now have further historical record of my GTV. The photos below were taken at Monza Motors on 15 August 2005 by Mick using his 3mp Canon digital camera.

Whilst he was capturing some gorgeous looking parts for his turbo Delta engine, parked next to the famous yellow Ignis GTV6 is my GTV with it's freshly installed 75 2Lt twin spark motor. The zender body kit and Simmons B45 wheels are still to be fitted. Whilst I'm very happy with my Borbet Type A wheels now on the car, the B45s looked great on the GTV.

If you're considering an indoor car cover for your GTV / GTV6 I can highly recommend the cover I bought from Victor Parts. It fits like a glove and is flock lined to prevent scratching the paint.
