Sportscar Prototypes & Grand Valley Released

[DaveO]

Speedsims proudly presents:












The 70s was the great era for Sportscar Prototypes endurance racing. There was lots of famous races that were run for 100-500km or even 12-24h all over the world. It was the time of big-engine high powered cars whose constructors had just learned how to make use of aerodynamics.

And this the era of the famous Porsche 917, who was the base and backbone of Porsche becoming a legend on every race track. The 917 was basically build only to make Porsche for the first time win the Lemans 24h - and it did. And more, much more. It did win that much races that

One of Porsche's fiercest competitors was Ferrari and its 512. Engineered even before the 917 came to life, it's more developed versions could sometimes beat the 917s. Both cars are outstanding race cars that represent the early 1970s endurance racing perfectly. Beautifully shaped bodies, with aerodynamics more been guessed than (like today) computed. Very high powered, running on incredibly wide tires, with almost zero down force - a challenge for each driver

Grand Valley:

Track facts: 2.8 Miles/4.5 KM This is a conversion by Smoke from the rFactor track by Ewan (Uzzi) Chalker, a scratch built track inspired by the track for Gran Turismo 1. This is the Long version of the prior Grand Valley East.

Check it out !

The Mod and Track have been a long time coming for Smoke and myself. ;D

It's one install for both the SCP and Grand Valley

Hope you enjoy it as much we did in creating it!!

Finally! remember the tires are big and wide but hard take a lap or so to warm up.

[grumpy]

Words can't describe this mod. Awesome Job DaveO!!! ;D

Smoke fantastic work on Grand Valley. ;D

Looks and sounds great dave! I think there is a problem with the template link.

It's gonna take some time for me to get used to the cars.

opps. Template link is now fixed.. Yea, it does take some time to get use to them. It's like the beast of the Group C cars, but the opposite with not that much down force. That's how these cars were built back in the 70's hardly any down force, and was left to the driver to figure it out. When starting out, add a ton of more rear wing, it helps.

Fantastic work Dave!!

[ucrdoh]

Just whipped up my own Ferrari. Lots of fun Dave.

[bover907]

All I can say is Wow, Dave! Those things are an absolute blast to drive!!!

I tried the Ferrari first, then the Porsche. I kinda liked the Porsche better. Seemed sportier to me. Took them both for a little test at Watkins Glenn, since it's my best RC track. Not much of a road racer here, but I did get down to a 1:05.878 in just a few laps!

Really great work! I love it! and that's coming from a purely stock car racer.

So... after doing a race in the Honda mod, I wanted to try the Sportscar Prototypes mod. A difference of day and night of course! Man these SCP cars are a blast to drive!

Me and Chris took the cars for a spin on the all new Grand Valley long RC track. Chris in the Porsche, and me in the Ferrari. These cars want you to push to the limit right away! You can tell they have alot of power. The mod is something different! I have raced, Group C cars, The Shelby, VTA's, Honda's, SCGT's, and so forth. But this is as well heaps of fun! I am looking forward to race the SCP cars in racing conditions.

The Ferrari seems like a strong competitor against the Porsche. I dont know yet which of the two I prefer. That'll require a bit more testing. But from the laps I did last night, these cars are a challenge to drive but great fun! A quality mod done by Dave. Big thanks to him for making this available for all of us to enjoy!

cheers,

Triz

Thank you all for the kind words on here and also @ TMS..

Smoke, has been with me on this quest since the very beginning. He gave tons of support, introduced some great car sounds that could be tweaked, and never lost faith that I could do this and see it thru completion. He saw my very first ever scratch model for this mod and watched how all the versions of the models progressed over several months , and was like a rock thru out this entire project. Also it is a great honor that he also wanted to release a track with my first ever mod. That in itself was a great honor to me, from our very own track master. Smoke thank you for everything. Plus as he knows Grand Valley is one of my favorite tracks!! Smoke, thank you!!!

The Guys from TMS Blaxman and Raybee, fantastic guys who never hesitated answering all my endless questions, and who gave moral support thru out the entire project. Those guys at TMS Rock!

Ron, who put up with all my endless questions. Hehehe Great guy and physics guru who taught me so much.

Cholerix, who came up with the idea to create this mod. Who also never hesitated answering questions on modeling, and giving great feedback in the earlier development of the mod. Miss yea on the track bud.

Spike, who showed me some great modeling techniques, moral support, and who kept me energized to keep going.

Triz, thanks so much for creating a brilliant video of the mod, your work is on equal par to a professional.

Most of all, to all guys at SpeedSims, you guys rock! Thanks for the support thru out this entire project.

okay enough of my babble. Enjoy the mod guys, and will be launching this mod with two other mods for some great online racing in March.

See you guys on the track!

Hello SpeedsimS guys,

It looks like nh will run on my computer from the next week on, too. Dave will help me and we have allready a date.

Those pics looks great and I can feel how proud Dave should be to get this work done very well to all the happiness of you. Will start testing it from next week on. Will check out the different car physics implanted in nh to rf. There I was riding the 512CL on LM67 track, Spa67 and Mount Panorama -Buthurst-.

Riding, I feel, is the better word. In rf it is no driving. You feel like the wheels are never on the tarmac. More like sliding on coal formed like an egg (called Eierkohle in German), and if I have seen your postings here, Dave was able to rebuild all the right mistakes those old cars could offer to the driver 1970.

Will need some days (or weeks) to get comfortable with those beasts, but if you are planning some races in March, I'll be inside.
And will try to get the 3:21.122 in 2nd race lap at rf LM67 CSGTmod with F512m in your nh mod (check out the "racingsportscars.com" for origin results and lap times under..\gallery pictures\all sportscar races\site 10). This site is a best use for myself to check out my bad or good speed in rf.

I was riding 70s cars not only with rf. In Germany, I was used to the slot-racing as well. At first with the smaler size 1:32, but more interesting is the scale 1:24, mounted on metal chassis. There you have to get a setup for each track as well. And, you drive on different track material like wood or plastic tracks from Carrera. Tires are smoothed on turning lathe or a smal turning lathe tool used at home and again on the race day (the plastic Carrera need to polish the rear tire with 2000 to 4000 corn paper for grip). Different rear tire material is used on wood or plastic tracks (PU on plastic - sponge rubber on wood), chassis and housing separated with springs with different grade, front and rear axle turning in ball bearings and much more.
Houses are used from Tamiya, Revell, ... till some small batch series factories (mostly resine).
For all are interested in check out "scaleracing.de". Ok, its in German (don't know English is possible), so use google for slot-racing US, England and Australia.
This hobby is not the cheap one, but funny. And a Japanese factory was realysing the houses for 917, 512S cc, 512S cl and 512m for the 5 Litre, different 908 and Alfa Romeo for the 3 Litre prototypes.

Back to Dave's work and some historic.
My office window was placed on an incoming main street in Stuttgart, Porsche town (and Mercedes). The Porsche 50 year anniversary get me jump to the open window as Hans Herrman was riding its 917 LM#23 to the Schlossplatz, where the party was going on.
Sound? Don't ask.
And it was visible, Hans Herrman still get problems to keep that beast on track!
All this and much more about the Porsche era is written in the book "Porsche 917". Porsche, the small car company was ready with the needed 25 cars for homologation.
More late was Ferrari with the 512S coda corte (coda lunga used at LM like P LangHeck -LongTail). Ferrari must sell some company percent to Fiat, to invest that money into the 512. And, Ferrari was one year to late. Porsche get running the 917 in 1969.

Porsche don't use a company team. They get teams like John Wyer, team Salzburg, Martini and other. So Porsche was free to construct and upgrading the 917.
Ferrari neglect its customer over years. Could sell cars to NART and other, but start with own team SEFAC. All this need time and manpower, not to keep quiet the Ferrari inhouse problem .
Maybe all those things come together, Ferrari could win the 12h of Sebring, only (outside the WSC70 Kyalami). Porsche wins all.

And more.
Porsche still was set up fine with the 3 liter 908 in different modifications, Especially on tracks like Nuerburg Ring and Targa Florio, the 908-3 kick all the big ones. The 3 liter Ferrari could not face the 908 and the Porsche 917 driver riding the 908-3 instead.
So Porsche easy win the WSC70.

Also we shouldn't forget the Alfa Romeo Tipo 33. On short and tight tracks this car was all the time a number and ready to eat points, Ferrari need to get a chance in 70s.

Ferrari was pressed into a corner and need to get better cars to face the 917. End of 1970, on the Salzburg 1000 kilometer race (Dave, races limited to 12/24h or 1000km mostly), Ferrari comes back with the upgraded 512S, the 512m (modificato).
The 512m shows up predominant to the 917, but again loose the race (Ickx/Giunti) with electric generator problems. The next race, 1000km Kyalami the 512m wins with 2 laps in front Siffert/Ahrens.

1971, Ferrari didn't use the 512m as factory team. Ferrari was busy with the new reglementation for 1972, when the 5 liter is kicked out of the WSC, because the Alfa Romeo Tipo 33 shows off in 3 properties, the 917 was beatable! Again Ferrari neclected the customer teams. Only Roger Penske could pretty face the 917. Penske upgrade its 512m (Sunoco) itself. But the Penske 512m often kick the race with technical problems (LM71 - Donohue/Hobbs), mostly in leading position.
Again a year for Porsche.

1972, the Ferrari inhouse problems grows up (Enzo's word was godmade), Ferrari loose Penske, Penske start at CanAm with Porsche's 917/10. Again a two year era for Porsche.
Remember Marc Donohue and the 917/30: A car only gets enough power, if you are able to pull a black strike from the end of a corner to the next braking point!
Those words are sign to Porsche.

Dave, I don't will tell you something or teach you. The pics here shows of great cars and all the guys respond you have well done a great job. Next week it should be my time responding you. I only was in historiy.

A little I miss the 512S cc / cl. Maybe, you will teach me a little in modding, and we get the allow from the CSGT-guys, we could use the rf 512S in nh, too.

In respect to all the guys, spending there spare time to get us such mods, tracks and cars.

Steve

thank you for your short history, and yes it was a very different world than racing these days. Technology levels were quite low then. i had a chance to talk with one of the drivers of the period, i learned that the 917 did not get into a wind tunnel until late in 1971 when it was almost retired. they learned at that point the air behind the rear window was stalled and all trim tabs, and wings in that area were almost totally useless. we did try to duplicate into this mod "feel" of the cars as in that period. just you and and some big tires and big engine against the track. By the way my roots started in slot car racing also.
ron.

[Blaxman]

Yeah!! Nice and interesting story, Stevewarson!!

I also had my days on slot car racing. My pro stuff was all sold a few years ago and the trophies got sadly lost on a moving, but I'm still have some vintage slot car stuff in good condition at home. ;D
