TR7 at Bathurst

Postby PeterTR7V8 » 20 Sep 2010 05:33

Now we know it takes about 3 minutes to complete a lap of the Mt Panorama circuit in a TR7 2L. Here's the proof. http://www.youtube.com/watch?v=mymtlkfjNVI

Anyone in Oz know this car/driver? This video shows the comparison between the 2L & the V8 on the track & it is much closer than I'd have expected. http://www.youtube.com/watch?v=1QEr_h6WCfM

TR7Racer is Jon, the current competition secretary of the Triumph Sports Owners Assoc NSW (TSOA NSW). His wedge is a Sprint running DCOEs, and the quickest of the Sprints in the club.

The dark V8 wedge that scoots away from Jopn at the start of the second vid runs a 4.6 on CUX14, Toyota Supra gearbox, BW LSD from a Holden Commodore, 5 link rear, and very big brakes.

The white Doli Sprint is turbocharged.

BTW, the second vid is not at Bathurst, but at Wakefield Park, near Goulburn.

That Bathurst stuff brings back memories.

Just for comparison, I dug out some of my records from the old days.

The track was a bit different, with murrays, & hell corner both much tighter, so low second gear corners, but no chase to slow the straight.

My Morgan +4, with 5"rims, & road tyres, [probably Pirelles], required by the regs, did;

In 63, with 79BHP at 4600RPM at the wheels did 3.20.9. I won the 1500/2000 class of the Le mans start 8 lapper. Flying 1/8Th 124.4 MPH

In 64, with 92BHP at 4700RPM did 3.06.2, which was a new lap record for under 2L Improved Production Sports cars. Flying 1/8 124.6 MPH.

To put that in perspective, My Lotus 20 FJ, 1100cc pushrod in 66 did 2.42.5 & 133MPH flying 1/8Th, & finished 3Rd outright in the Bathurst 100 [miles] Formula 1 race.

My F2 Brabham, 1100cc in 67 did 1.36.1 [a lap record never beaten] & 142MPH. Also finished 3Rd in the Bathurst 100 F1 race.

In the Scuderia Veloce Brabham Repco 2.5L formula 1 in 68 did 2.15.5, which would have been the first ever 100 MPH lap of Bathurst, if some bloke called Kevin Bartlet had not done it a few laps before me, & a couple of tenths quicker.

Still, he broke his car, so that year I won the Bathurst 100, second only to the AGP in importance back then.

68 was the first year of the Holden Monaros. We & the Ford GTs were doing just under the 3 minute mark when flat out, & running around 3.3 or 3.4 continually, so very similar to that Triumph. My Monaro was getting 128 MPH down the straight, but the quickest were getting 133 MPH. I think the Triumph was a bit quicker than that

A real comparison is the climb up from the cutting. In the Monaros, we were on 6" rims, & XAS Michelins, & I could leave it flat [but only just], from the cutting right to skyline, so that Triumph must have some poke.

These guys are having waaaaay too much fun. Those concrete walls are a bit unnerving but better that than hitting a tree.

Yes Spyder those walls do kind of spoil the look of the place, although it is much safer. It used to be one of the prettiest race tracks, as well as one of the best.

We used to be able to look out over the town, & the whole valley to the left, as you came across the top. Skyline was much more daunting, as sky was really all you could see as you came up to it. The wall now shows you where the road goes.

In much of the 60s the only thing between us & the spectators was about 15 ft of grass, & a barb wire fence. We used to pull into the pit area with no fence between it & the track. Blokes were changing wheels, & brake pads with cars going past at 100MPH, just 15 ft away. A bit silly really, but still, I don't remember any mechanics, or spectators getting killed, only drivers.

You really have to do that run across the top of the mountain to realise how good it is. The car goes light & heavy loosing & gaining grip, as it goes over the waves in the road. The feeling is incredible.

I raced there for 8 years, & never got a single scratch on the car, but it really did sort the men from the boys.

My first thoughts watching the video was a comparison with the Nürburgring Nordschleife. Which is still the best track I've ever seen.
That steep down hill section looks awesome [:)]
