How to build a Superlite that's actually super-light

OK, sure, 2500 pounds is pretty light for a production street car, but it's pretty heavy for a race car.

I'm wondering how light one could build an SL-C?

Horse-power can't make up for weight. I think Colin Chapman had the right idea back in the 60's with the Lotus 23--1,000 pounds and 150 horse-power, or 6.7 lbs/hp. Jim Clark absolute killed those Porsches and Ferraris at Nürburgring in 1962. Then they banned them from Le Mans!

Most of us can't come close to effectively using 500 hp around a race track. I know I can't. I've got a Formula Ford that I race with the SCCA. 1100 lbs with driver, and 110 HP--10 lbs/hp. And I'm still trying to learn how to use that. I couldn't use even a fraction of, say, 500 hp in a 2500 lb car. I'd probably just kill myself!

Maybe I could eventually learn to use 8 lbs/hp. That'd be 312 hp for a 2500 lb car, or 250 hp in a 2000 lb car. Something like a Lotus Exige, for example (2,060 lbs, 260 hp).

Could an SL-C track-day car get down to 2000 lbs? How little would the engine and transaxle have to weigh?

What light-weight engine could be used to produce 250 to 300 HP?

  • Flat-6 from a Porsche Cayman?
  • Something from VW/Audi, like in the Nemesis? V4 turbo or V6?
  • Subaru flat-4?
  • Other lightweight V6's?
  • Super-charged V4's?

I think I wouldn't even mind the noise of a racing gearbox, but I probably can't afford it. Sequential paddle-shifters on the steering wheel sure would be nice though. What gearbox can do that?

Besides the engine and gearbox, where else can one remove weight from an SL-C?

  • Wheels and tires. What size?
  • No sound-insulation.
  • Unfinished interior.
  • No AC. No audio.
  • Gel-coat only--no paint.

Of course, I would want full safety equipment for the track. A cage, racing seats, 6-point harnesses, fire system, fuel cell.

Cost matters too. Could I do this for $65,000?

I appreciate any thoughts on this.

Thanks,

Greg

Re: the importance of weight over power

To illustrate the importance of weight, I've gathered some lap records for various SCCA racing classes at Thunderhill. This is taken from San Francisco Region of the SCCA. You'll notice an entry for the SL-C (record by Michael Skeen for Team QRP). This is sorted by lap times.

And here is lap times plotted against the weight/power ratio.

laptimes-chart.GIF

What's interesting is that the SL-C, while having a fantastic weight/power ratio of 4.9, can't make up for the fact that it weighs twice what the other cars weigh. For example, Formula Atlantic (1230 lbs), while having slightly more weight per hp (5.1), is over 8 seconds per lap faster than the SL-C. The SL-C is turning laptimes closer to Formula Mazda (1350 lbs), which has a ratio of 7.5.

A similar case is the Porsche Cup car (2775 lbs), which has a ratio of 6.7, but is 8 seconds a lap slower than a Formula Continental (1200 lbs), with a ratio of 7.3. In fact, the Porsche is slower than a Formula Ford (1100 lbs), with a 10.0 ratio. At least the SL-C is faster than a Formula Ford!

At the other end of the scale, there's the DSR, which only weighs 900 lbs with driver! With it's 1.0L motorcycle engine (definitely lacking in torque) making only 200 hp, it kicks the ass of everything else here. 11 seconds a lap faster than the SL-C, but a similar weight/power ratio (4.5 compared to 4.9).

All this just to illustrate that 525 hp can't make up for a 2550-lb car. You're better off taking off weight than building a bigger engine.

Which is exactly what I want to do with the SL-C. After all, it is an incredibly sexy, well-engineered car, plus it seats two, which very few race cars do!

Ernst--

Yah, motorcycle engines make a lot of sense in a 900-lb car, like a DSR. And they have a sequential gearbox built in. They also sound really great at 12,000 RPM!

I don't think they'd survive in a 2000-lb car like the SL-C, though. And they're low on torque compared to an automotive engine. I also don't want to try to fit a chain drive to the SL-C.

Thanks for the suggestion. Keep 'em coming!

A nicely trimmed SLC is around 2450-2500lbs, that's AC, electronics, plush interior,, yadda yadda. The Kit itself with a G50 transaxle weighs 1750lbs (IIRC), and that's with a lot of stuff included. Check out here (http://www.gt40s.com/forum/rcr-forum-rcr40-slc-p4-mkiv/29839-how-light-superlite-coupe.html), it has a good breakdown of part weights.

2000lbs is very doable, if you really pay attention to stuff, you have to start thinking outside fo the box to get lighter than that.

Engine/Transaxle Weight Savings (100-180lbs)

If you went with a lightweight V6 (4cyl is out of the question due to lack of power), you could save around 100lbs vs the LS V8, VQ37 weighs a scant 315lbs. The lightest transaxles can weigh just over 100lbs, so maybe 45-80lb weight savings, though you'll only have a 4 speed.
-



Body Weight Savings (30lbs?)

You could save a bit of weight if you had "mad skills" and could mold the front and rear clam shell and make them out of CF (the material itself would not be too expensive as carbon fiber prices have dropped a lot), you could probably get enough CF to do it for 3-5grand, but to be totally effective, you would need an autoclave to vacuum and heat it. (30lbs at least)
-




Chassis (20-40lbs?)

Replace front windsheild with lexan/polycarbonate (10lbs?)

Fabricate and replace roll cage with Chrom-Moly (can be made a bit thinner, though not sure if it is race-legal. Or you could try to replace the 6point roll cage with a carbon fiber shell, though again, not sure about the race legallity of it all. (10lbs?)


Replace the rear engine brace/crossover with chromoly (5lbs?)

I guess you could save a few lbs if you replaced the suspension with hollow tube chrom-moly.(2-3lbs)


Replace all the single piece rotors with two piece w/aluminum hats (10-15lbs)


Replace stainless steel cooling pipes with aluminum (2-3lbs maybe?)


Litium/Ion battery vs drycell (10-30lbs - depending on what you are replacing)


Find the lightest wheels and tires you can get, yes, tires can vary by 5lbs each as well, being that you are going that light, you could get away with narrower wheels and tires, which would further reduce your weight.


After that you would have to get very drastic (as if those above in most cases weren't..lol),


The chassis is very beefy. I found that out when drilling through the front to make the holes for the brake reserviors and electrical. I felt like I was drilling to China, the aluminum is VERY thick (1/4 inch), which may not sound like much, but compared to most cars, it's build like a tank.
 
Body Weight Savings (30lbs?)

Last thing you forgot regarding "body weigtht" : put the driver on a serious diet, or/and on gym program, you'll save 20 lbs (depends on the driver's stature !)
Cheap, and good for your health, if not easy...:devilish:
 
A turbocharged 4 cylinder such as a 4G63 or 2.0 VW can easily put out 400hp and 400 lbs torque with off the shelf modifications. It's a route I was considering taking the SLC.

Then the GT-R came out...
 
Another way to reduce weight is to run lighter brakes. My SLC is one of the older ones, and came with the original Wilwood brakes. Like the current ones, they came with a one-piece rotor. Just by moving to 2-piece rotors the car dropped 20 lbs in front, and around 12 lbs in the back, IIRC, and all of it unsprung weight. And the new front rotors are actually thicker as well, for increased mass, which typically helps modulate peak heat in the rotors.

IOW, lighter overall weight, reduced unsprung weight for better handling, and better braking. And all it cost was more money! :)

The current cars with the larger Brembos have even more to gain from a similar approach.


I think it is possible to build a 2000 lbs SLC, but the drivetrain will likely have to be a light 4-cyl, or a super exotic V8 like the Hartley, which weighs only 200 lbs but is no longer in production.

And everything you add to the car will need to be weighed and considered. For example, on a really light SLC you might be able to save weight by swapping out the stainless coolant tubes for a lighter-weight aluminum. Transaxle choice matters, as there can be more than 50 lbs difference between the typical choices, and even more if you cast the net wider.

I'd echo the wheel and tire weight as well. Most everyone understands that lighter wheels are Good, but there is also a substantial difference in tires as well. There is a substantial weight difference in Hoosier R6s compared to say, the standard Corvette GY runflats.

Wheel diameter also matters. There is a reason that the DSR cars run 13" tires and wheels- all things equal, they are much lighter than say an equivalent 15" diameter wheel and tire package.

Battery choice and location also makes a big difference. My own SLC, despite a relatively light battery, still pays about a 20 lb penalty over a Lithium battery located in the back of the car.

Even "small" things like alternators can shave off a considerable amount of weight. For example, most GT teams in the Tudor series run a $3000 alternator that is race specific- and very light, probably 10 lbs lighter than a "regular" one. Even things the front engine dress matters. I have a custom billet front dress that is probably 10 lbs heavier than a simpler, not-so-cool variant might weigh.
 
20 lbs for the driver ha. most guys are 30 to 50 over weight. so stop eating and save that weight. my two cents on this. is if your goal is to change the complete car then its not the same car you started with. so start from scratch and go from there. the Slc is a great car as it stands just like the GT40 are for what they are. if I was the builder of a car and spent my life work on it and someone started telling me how to do it I would get bothered by it maybe Ron doesn't so all it good. when my car is in the shop and a guy walks up and looks at it I will say its my car nicely and if you have ideas to make it better keep it to yourself. this happened after one day my car was being worked on in a shop my car is a 69 mustang that does 11.5 quarter mile. the guy walks in and says my car is faster , so I have to ask what is it, he says a boss 429 stock. I say no your wrong its not. this happened for a few minutes until I told him nicely he's an idiot and go away. so end to a long story, it is nice to dream out loud but don't stomp on someone else dream.

If you're after a light-weight track day toy, why not get a Nemesis? It's be cheaper and and better suited to a light, motorcycle engine and gearbox.

Going much below the typical weight for a track SLC is going to cost quite a bit, unless you want to pedal :)
 
Yup, its all in the details. Save a little weight here, there, and everywhere as you build the SLC.
  • You will feel savings in unsprung weight the most. In particular, the unsprung spinning bits have the greatest impact, such as lighter tires, forged wheels, and 2 piece disks.
  • If you don't mind a 4 speed, the 930 transaxle will take V8 power and save 25-30lbs vs a G50.
  • The LS motor is still a lot of power in a small package. Its lighter than just about any other V8. Its even lighter than the Porsche boxer 6. Other alternatives are the Subaru WRX STI (motor & trans), Audi (motor & trans), Ford Eco boost 6 from 2014 F150, Ford Eco boost 4 from 2015 Mustang. After seeing the Buzzy SLC youtube video (Garry Buzzelli), I have a whole new respect for the 3 rotor Wankel as well.
  • Use aluminum rivets instead of steel fasteners where ever appropriate. The difference in each fastener isn't that much, but add up all the fasteners and it's a notable savings.
  • Fabricate brackets from aluminum instead of steel. I'll bet I've fabricated less than 5lbs of steel brackets. All the rest are aluminum.
  • Use sound deadening materials sparingly. Its easy to add 100lbs in materials like dynamat, Mass Loaded Vinyl (MLV), LizardSkin, acoustic foam, etc.
  • Use a smaller AGM battery vs a tradisional wet cell lead acid battery. An Odyssey 925 has plenty of cranking power and weighs just 25lbs (vs 75lbs).
  • Stereo! You don't need no stinkin' stereo!:drummer:

Hey Jack, that data is really helpful. Could you attach it as an .xls file?

Oh, never mind. I see your data is the same as Dave Lindemann's (which is available as an .xls file), with the addition of 400 lbs for an LS3 engine.

According to Dave's spreadsheet, with a G50 transaxle, he's at 1735 lbs, leaving 265 lbs for an engine, if the target is 2000 lbs.

I don't know engines--is there such a thing as a 265 lb engine that produces 250 HP, and is reliable/long-lifed?

Thanks,

Greg

Greg,

If it's the same data as the one Dave Lindman did, it is attached on the link I posted a few up. Go to my post and click on the link. It's a link to How light is the superlite here on GT40s.
 
20 lbs for the driver ha. most guys are 30 to 50 over weight. so stop eating and save that weight. my two cents on this. is if your goal is to change the complete car then its not the same car you started with. so start from scratch and go from there. the Slc is a great car as it stands just like the GT40 are for what they are. if I was the builder of a car and spent my life work on it and someone started telling me how to do it I would get bothered by it maybe*** Ron*** doesn't so all it good. when my car is in the shop and a guy walks up and looks at it I will say its my car nicely and if you have ideas to make it better keep it to yourself. this happened after one day my car was being worked on in a shop my car is a 69 mustang that does 11.5 quarter mile. the guy walks in and says my car is faster , so I have to ask what is it, he says a boss 429 stock. I say no your wrong its not. this happened for a few minutes until I told him nicely he's an idiot and go away. so end to a long story, it is nice to dream out loud but don't stomp on someone else dream.

Ron??

Not sure what the Subaru EZ30 6 weighs, but @ 185kw/250 hp for the R 3.0 version its in your ballpark. The 3.6 version now available in the Tribeca etc might be more, worth a look. A few outfits doing straight cut dog box internals for the Subaru transaxle as well. Check out the Saker stuff to compare.
 
The EZ30R from what I heard is about 240lbs (that dry weight, not dressed). I wouldn't mess with the 3.6, IIRC its just a really long stroke, and they used offset connecting rods for it to clear.

A buddy of mine was wanting me to put a EZ30R in my SLC, yes, it sounds awesome, and is silky smooth, but you will spend a fortune to get any more power out of it. Though there is a guy that did a turbo on it on NAOSIC (or however you spell that website).
