I wonder which chassis this car uses

Fran you never cease to amaze me, you have your fingers in to more things then anyone I have ever known. How many fingers do you have, I am going to start calling you Hecatoncheires.
 
I think the SL-C looks great but not sure if it's too my liking, I'm reserving judgement untill I see it in person as quite a few people have said photos don't do it justice.

Question is, how to make an SL-C loose another 350-400lbs without going to extremes.... I've driven 900Kg cars my entire life, anything more, even 1000Kg just feels like bloat to me.

The SL-C / RCR have continued to impress whether it's the SL-C setting records proving itself or RCR's continuel involvement with other projects where people have come to Fran.

He must be doing something right.

When I first saw the SLC in an issue of Kit Car mag, I thought it was good looking, but nothing over-the-top great. During that time, I thought that the GTM looked great. The first time I seen an SLC in person was at the SEMA show in 2010. Seeing it in person??? HUGE difference. Seeing the GTM in person??? HUGE difference. The SLC in person is automotive porn.sTud suspension bits, carbon cross brace, LS376 and Ricardo trans in a very clean, well finished, engine bay is beautiful. Seeing the competition??? It's bloated, has a very "kit carrish" interior, and has massive overhangs front and rear, as well as a bunch of other issues. The GTM is just massive.

I'm just babbling at this point, but the SLC is what it is. It's proven on the racetrack. It's proven to be a relatively simple car to build. The factory support is excellent. The car is simply the best. FACT!

I think you can build a 2000 lb SLC, but it will be a pretty spartan car. Fran was talking years ago about doing one just to show it could be done.

Alternatively, it may be that the problem is that the "even 1000Kg" cars you have been driving just don't have the dynamics that the SLC so clearly does. You should try it first, then decide. Pit Row Sports actually rent a track-day SLC with an LS7, and you could try that out before committing to a car of your own. It's the same one he says saw an indicated 194 MPH at Daytona.

If low weight is the only criterion, maybe the new LMP Cadillac RCR is building, or even the SL-R, might be a better choice. The SL-R is still around 1500 lbs, even with a relatively heavy car engine like the Mitsubishi. A lighter drivetrain could easily drop that another 100-150 lbs. And then you could use smaller wheels and tires, another source of extra weight, etc.

As to looks, you really do need to see a finished one in the flesh. It has a presence that few other cars, street or race, have. Once you've walked around it, sat in it and made vroom noises, then you can decide if you like the looks.

The next step is to actually drive one to see if it has the dynamics that you've been missing in lesser cars.
 
Ben,

back in 08 you were asking me about installing a 5.4 Mod Ford and Ricardo....no way that was ever going to under 900kgs...:shocked:

What kind of powerplant do your "under 900kgs" cars have ...surely not an America V8/transaxle.?

You are welcome to come by anytime but lightness costs money....so bring your cheque book.

Yeah, that was 3/4 years ago, I know better now.

And you are thinking waaaaay too big, I never said the cars I drove were powerful ;)

The first car I drove for years was a Mk1 Fiat Punto, the second (and current) is a Toyota Aygo, both of these rustle up massive 60bhp but weigh next to bog all (around 900Kg).

Clearly the go wasn't a priority for me so much as the stopping and cornering (not that these cars were ever considered good handling). What they lacked in good suspension/chassis, they made up considerable ground in the fact that they weighed virtually nothing.

Admittedly I did own a Jaguar XJR for a while (the aluminium bodied X350 variant) and that was a mere 1.8/1.9 tonnes, it was surprisingly quick in a straight line, certainly faster than you would think given the weight but then 4.2L supercharged V8's do that. Where the weight was EXTREMELY apparent was when braking and even MASSIVE Brembo brakes which were in perfect working order and good pads was worlds apart from braking in the Aygo weighing in at probably HALF the amount the XJR did.

Sprinkle in some experience with Lotus Elise's hand having owned/ridden numerous super sports 600's and you can see what I'm getting at.

On the flip side I'm sure Will is absolutely correct in that the 'larger' cars I have driven will be severely lacking in the agility department where the weight (and most obviously how it was shifting around) would have been more apparent.

Let's be honest, driving a 'hyper car' such as an Enzo or Mclaren F1 will be WORLDS apart from anything I've ever experienced, even the best of handling cars I have ever driven/been in and they would blow my mind (I noted a while back that an Audi RS5 really was quite impressive and that isn't exactly lightweight).... but if those 'hyper cars' would blow me a way and an SL-C is seemingly more capable....

So it's not that I'm aware of the differences....VAST differences in what I have driven compared to what the SL-C is capable of.... It's just a preference, with my money I'd head down the lighter weight route Vs. more power.

Stock LS3 and maybe a ZF-Q transaxle or how is the Griffin weighing in at compared to the Ricardo? I'm sure that would go a long way towards a goal of < 1000Kg.

Like I said, I need to visit RCR/Fran and talk some cockney rhyming slang.
 
And not the V6 in the current Mustang? Seems like a pretty good lump to me, not sure how much it weighs though.

Sounded pretty nice even with stock exhausts.
 
I was thinking of going with a VQ37de and turbo it. The VQ is 330lbs, add a couple of lightweight EFRs and intercooler and you might be bumped to 375lbs or so, The LS is 460lbs, so you are saving at least 80lbs or so. The VQ can do 500whp on stock bottom end. If you look at the torque curve, its pretty flat

That would be quite unique and killer. How much money would such a set-up set you back?
 
Triple rotor rotary? Not cheap, not that reliable, not as much low down torque but going to be very light (and small) for the power.

The rx-8 twin rotor with everything on is I believe just over 120kg and 250 ish bhp (in jdm spec)
 
Yeah. Even if it says it has the same chassis as the SLC, which it doesn't.

It's actually a specific chassis for the Falcon, but with a lot of the usual Superlite DNA.

But any PR is good PR, right?

I hope the car does well!

Yep and they link directly to the Superlite site instead of another of their stories/articles so at least that was nice.

I imagine the site is seeing a fair increase in traffic right now!
 
Again, y'all seem to be glossing over the fact that you guys have a seemingly very good V6 already under the Mustang hood which I bet can sound just as nice with the right exhaust.

And whilst the 370Z's V6 makes a little more power I wonder how the rest of the specs compare and more importantly, which company is willing to sell you their V6 in crate form and at what price (granted only if you want brand new).
 
Not too sure on the Ford V6,, but the VQ37 is

- 330lbs (that's crazy light) (I believe die not sand casted)
- VVEL (Variable timing and lift,, not just cam phasing)
- Forged Crankshaft

I'll have to look up specs on the Ford engine. I do know there is a lot of aftermarket parts available for the VQ from forged pistons, rods, valvetrains upgrades,, ect. The engine has been around for a while. In fact I think its only downside might be that its an open deck,, but even with that people have been pushing 700-800 hp out of those things without a hickup.


Did find one fact,, the ford V6 is 430lbs,, 100lbs heavier than the VQ.

Sounds like a it'd find quite a cozy home in an SL-C... although anything other than a LS has yet to be proven.

An auto enthusiast could hear a 370Z with an exhaust drive-by and call it ricey; while if they saw an SL-C fly-by then the note immediately enhances into exotic :D
 
Ryeno...we have Ford Coyote...TT Lexus...SBF....SBC 410 sprint car engines in SL-C's... and just recently a supercharged Honda 4 cylinder engine package was chosen...and thats not to mention the diesel engine....
