105 v Alfetta v 75 Track Times. Whats better?

[vin sharp]

::)Good GpS historic Alfettas and 105s will do 1.54secs and under at Phillip Island, with 60+ year olds driving... That's with a Nord engine on carbs, 185/60 treaded race tyres and standard size solid brakes and calipers, and all steel body. An equally set up 75 would match that or within tenths.
How many very modded, stripped & lightened Alfas ever get near that potential?   

Remember when sub-2 minutes was considered quick?  Is it tyres that have improved this much or?

It's a bit of everything, nothing stays static. Drivers in particular learning how to make the best of what they are limited to within the  historic class.   Shows what can be achieved with what is a relatively mild allowance for changes from the production car.

That's still a lot faster, it wasn't that long ago that the very fastest club cars were only around 1:50.  I'd have to go back and check times from 10-15 years ago to be more specific.

Further to Vin & Aggies point about time never stands still, well apparently that's true in 2 litre  Alfetta land as well. A quick but by no means exhaustive search of Natsoft results shows that around 2000 . Joe Ardi was the man to beat in  Alfetta's . A 1.58 at Philip Island in Marque Sports. A few years later in early Group Sc in around 2007 Phil Baskett was again doing 1.58. (different class / different rules) . 2021 Hugh Harrison in group SC had lowered the bar to 1;54 Secs. (Sorry Vin i was unable to access their birth certificates)

Joe Falcone mentioned earlier that a twin spark Alfetta GTV would be the way to go. I tend to agree as i have a road registered one in the garage. I haven't been doing any club sprinting for a couple of years now , but when i was Joe had a reasonably well sorted road registered Alfa 75 TS ( apart from undersized torsion bars ) . Over 3 years there was never more than a second between us at PI , Sandown or Winton.
Your also mentioned you tube clips. If you want some real excitment look up Steve Aarons in an Alfetta Twin Spark at Philip Island . The 100mph power slide through turn 1 at PI wasn't bad . Or spinning 360 degrees and pulling up straight going down the main straight in torrential rain after an innocent enough gear change ( i was behind him for that one and had to close my eyes , i couldn't watch) . That boy will never die wondering.

Yes Paul smile factor and Marcus's lap times would favour our point of view

[Colin Edwards]

Yes.  Difficult to compare apples with oranges. 
Most things being equal, the Alfetta is around 100kg lighter than the 75, however the 75 would have 10% more power.  The 75 is about 30mm taller than the Alfetta, while both have a similar track.  The 75 would likely have a higher CoG and transfer more load, however the 75 being a later design "should" have a torsionally stiffer chassis.  Then again the 75 is more aerodynamic!
  Decisions decisions.

Both are very collectible - the Alfetta more so, however the 75 is catching up!   

A 1.4 Multiair equipped Mito would be way faster, and safer - and for the moment, less collectable!

Joe Falcone "Yes Paul smile factor and Marcus's lap times would favour our point of view"

Right again Joe and apologies to Marcus Gordon 1min .52sec . in an Alfetta GTV TS sports sedan . ( does make Hughs time look remarkable) . Pushing the envelope a little further Peter Beninca's low flying aircraft Alfetta based sports sedan 1min 39 sec at the Island.  Nearly forgot the ultimate expression of Alfetta . The Tony Ricciardello Chevy / Alfetta. 1min 29 secs at the Island

They just ought to start making Alfetta's again in kit form. Just tick Chevy for engine option

[Beatle]

Think of this as pub talk rather than science .

OK, given this is pub talk, and we've now introduced Chev V8 engines...    how's about actually building a car.  A spaceframe chassis with mid-engine 3.2V6?   Or Alfetta transaxle-based RWD V6.  Might give one the opportunity to 'correct' any geometry issues with the road car chassis (roll centres etc) and should be significantly lighter than any 116/160 RWD. 

[GTVeloce]

There is a company in Switzerland (OKTech) who is producing some amazing stuff with mostly GTV6's and 75's. Certainly his engine work (almost all N/A V6 related) has to be up there. I couldn't find the video I wanted but this shows a 75 race-car he has produced that, in the right hands, should be quick.

Just for the record

December 5 1999 Aroca club sprint i achieved a lap time of 1:54:84 in this 2 litre alfetta GTV
