@ Super8: That's kind of cool that some race cars from the 60s are road legal.


User avatar

Super8  8y ago

@ Shaggy: Yeah. I did not expecting that too. It probably because they had race car equipment. But they still road legal thought.

@ Super8: Quick lap times for such old cars, and the fastest is the Shelby Cobra Daytona Coupe.

I got another laptimes. It's for Suzuka. In Suzuka all the cars the slow in Tsukuba become a king in this tracks.

@ Super8: I'm pretty sure Shelbys are track monsters for their day, the late great Carrol Shelby was a road racer, after all.


User avatar

Super8  8y ago

@ Shaggy: If yo think Dodge car is impressive at tracks, then you should see Shelby cars. They tested both 1967 GT500 and 1965 GT350R in Tsukuba and the result is amazing. Six Pack Challenger might be fast but It still had some over steer on tight corner. But when I saw Shelby cars running... I simply amazed. It's very tidy even for an American Pony. The driver said, it's feel like driving European sport cars in same year. Not too easy but not too hard.

@ Viking: That's why I chose the 440 6-Pack for short, tight tracks. ;)


User avatar

Viking  8y ago

@Shaggy
From the videos I have watched, it appears that Tsukuba is a pretty tight track. I would guess that on period style reproduction tires (not grippy much like the O.E. rubber) that lighter weight and balanced handling will yield the better lap times. I think that while the Hemi is more powerful, it adds maybe another 100 or so pounds to the front of one of these Mopars compared to the 440 Magnum.


User avatar

Shaggy  8y ago

@ Super8: On drag strips and long tracks with long straightaways, I'd still choose the Hemi, on shorter tracks, the six pack so I wouldn't be spinning wheels for half the lap.


User avatar

Super8  8y ago

@ Shaggy: Yeah, Six Pack Challenger still considered as the best handling chracteristic first gen Challenger. It's not too powerful engine make the car agile on the corner. Six Pack is your wepon on track race.


User avatar

Shaggy  8y ago

@ Super8 & Viking: Maybe the Dodge Challenger with the 440 6-pack is faster around a track than the Hemi Challenger because the 6-pack is easier to handle/drive the 426 Hemi still remains one of the most powerful engines ever put into an American production car.


User avatar

Viking  8y ago

Yeah, I completely agree. Groovy comparisons would be possible. Gotta go to bed, it is nearly midnight here in California, and I have another wine tour to lead tomorrow. Good night. :)


User avatar

Super8  8y ago

@ Viking: Also, If you noticed. There are 3 Dodge Challenger in that lap time. 2 are restored by my father's friend while the other is my friend's car. If you notice, 440 Six Pack has faster lap time than Hemi also it close to Cobra 289 S/C. It can be really great if we can compare that on compare section so we can really know who's better on tracks not just on straight line :D. And if you noticed, most of Shelby cars are great on tracks. GT500 has same laptime like Nissan 300 ZX on Tsukuba and even GT350R is faster than both of them. It's really fun and also prove that not all old muscle cars has bad track performance.


User avatar

Super8  8y ago

@ Viking: I also thinking the same. The source that I got is only the year when the test is did. It's not recorded on official Tsukuba, Ebisu and other tracks record and decide to not published. They keep the record for their own. So, it's a big deal to get another proof besides people's eyes who were there. But I assure you, this lap time is really happen. Like you've been said, yeah it's cool if we can compare it to the newer cars or simply compare between 2 legend like Shelby Daytona and Ferrari 250 GTO. But I think for this time, I better post the laptimes here on comment to avoid some spank or evil critique.


User avatar

Viking  8y ago

@Super8
I have frequently checked up on cars that you have added, and I consider you a reliable source. I think it would be great if those lap times got added. I don't think we will find another source for accurate lap times for these classic muscle cars. I wish that I could think of a way to make the lap times verifiable to the admins. If they do get added, it would be cool to compare these classics. :)


User avatar

Super8  8y ago

@ BR2+: I agree and I already said that before I add that lap times.
@ Mental: Cool ain't it? That car already fully restored with modern 440 Magnum engine with more accurate power rating and modern 6 bbl carbs designed to look like original Challenger carbs created by Holley. So, it has real 390 hp and 490 ft-lbs and also more agile. That's the reason why it can beat that 300ZX Turbo. Also it faster on track than the Hemi model. Just like most people said. More power not always better. Enough power will bring you fly.

If we can add Porsche Laptimes, we should be able to add yours.

However, its only hearsay, there is no shred of proof whatsoever beyond word of mouth, If were we to add your laptimes, what would be the difference in other people just saying they did laps too? I could say I ran my Nissan and my Mazda round the Ring in 6:42.5s, and it could be added without a source beyond what I say. I say we should add them ONLY because we can add Porsche Laptimes or other manufaktur claims, but I also say we cant only because of no proof what so ever.

Member or not, company or not, I think proof should be available for every lap regardless of claim.

Mental  8y ago

I believe Super8 with those laptimes. I think the site would get even more exciting if the laptime database was wider for classic cars. Nice to see some the best supercars of the past taking part in that competition. Ah, if there were also sources confirming that, would be excellent...

"1970 Dodge Challenger R/T Six Pak: 1:11.29 (Original and Restored. This is the fastest old Dodge in here)"

Oho! That's impressive! I did not expect a heavy old muscle car to be faster than much newer Nissan 300ZX Turbo.


User avatar

Shaggy  8y ago

@ Super8: I don't see any problem with those lap times either, you're a well reputed member and have always added honest specs and lap times, heck, some of the things I learned about American muscle cars I learned from you, and you're Japanese I'm American, your knowledge of American cars is impressive, especially for someone as young as you are.


User avatar

Super8  8y ago

Unfortunatelly, admin just delete every single lap times I add earlier. Admin here doesn't like a lap time with no source.
@ Viking: I've been told you before. None of them will ever believe. They're to skeptical to believe while most Japanese always "closed" when doing something and keep it for their own. They don't like to share.

Ebisu

1967 Toyota 2000 GT: 1:20.87 (Original and Restored but had different tires than original)
1991 Mercedes 190E EVO II: 1:10.75 (Original. Driven by my dad)
1969 Dodge Charger R/T: 1:14.65
(Original 440 Magnum. Restored)
1969 Dodge Coronet Super Bee: 1:14.33 (Original 40 Six pack Restored)

Viking  8y ago

Yep, I still think these are legitimate lap times. Original and restored should be fine (at least as reliable as some factory lap times I think). Reproduction parts used in restorations are sometimes better than the original, but they are made to original specifications. Sometimes a "good" manufacturer was able to make their parts as good as any modern reproductions, so I think the restored cars should be fine as long as they are done to stock configuration.

...If we can add Porsche Claims, don't see why we cant add those..


User avatar

Super8  8y ago

@ Shaggy: My dad is a mechanic and most of his friend were also mechanic specially for restoration old cars. Before they sold it, usually they test it on tracks mostly at Tsukuba. But they also test it on other tracks like Ebisu or somtimes Suzuka. All of this car is restored and had original modern part so a lot of them can set faster laptimes than the unrestored one. But the problem is, it's impossible to get any other source besides people's eyes who were there because they doing it closed. But, I ask Viking yesterday he said it's OK as long I can explain it. So I might gonna add it here.

@ Viking: This is probably the chance to see rare car laptimes for everyone. One event that amuse me very much is when they test the Amilcar CGSS. You won't see any other laptimes besides this even it's only replica. Also, the one that amuse me so much is when they test both Ferrari 250 GTO and Shelby Daytona. It's really fun and amazed to see the legend goes battle again in modern era.
