I was constrained by that requirement, and so settled on an AHS steel chassis with aluminum panels.

It turns out that your engine’s redline is actually too high even with CNC-milled parts - 9000 rpm is more than they can take in the long term even with so much strength. Moreover, my engine, while larger (by almost 100 cc), somehow manages to have similar economy, even more power, and a more immediate power delivery. On top of that, it is just as tuneable, and fairly cheap, since I set all engine quality sliders to 0.

If I’d have dropped the redline 500 RPM, I’d only have valves complaining. As for efficiency, power, and delivery, I never claimed to know what I was doing with VVL. I’m probably using a smaller turbo than you are, which explains why I have less overall power and yet a lot less of a turbo spike.

Ah, and I see another crucial difference: Look at our wheelbases. You’re using the bigger car, I went one down in size. My engine’s a bit of a squeeze lengthwise, but yours appears to be fine (There is a reason I run with colorblind mode on…) as far as I can tell.

All that power does bite you, though. Your service costs for the engine are a little higher than mine.

It’ll be interesting to see which of our cars places better in the end. A lot of similar design choices between them, but two different outcomes because of our own preferences. (Honestly, my original version wasn’t going to be turbocharged, but it just didn’t feel right without it.)

@strop Can you clarify the effect of suspension type on tinkerability? It sounds like (based on eng. time and PU) that solid axles would be the most tinkerable, and multilink/pushrod would be the least. This doesn’t make any sense, of course - solid axles can’t be adjusted.

The same goes for a few other things, such as the differential - an open diff has low engineering time, but there’s no tinkerability there at all.

the reason i used alu/alu was for eco-ness. pricing wasn’t too bad, as it’s still under 30k

i used a bit of slider and quite pricey bottom end parts though it is a more expensive engine.
because weight reasons

Hatchback or coupe that is the question.

1803

I knew as much; I was sure that my engine would not fit in the smaller version of the body I used. It fits in the larger version, though, but it is almost as long as the engine bay will allow, though at least it isn’t very wide.

Taking what we learned from the Hasira during the Barely Street Legal League, Normandy up and decided that what it needed was a direct competitor to Chevy’s Corvette, Ford’s Mustang, and Dodge’s Viper. In effect, it needed a Pony car. A modern, point and squirt, muscle car. The problem is… Normandy doesn’t like cars that perform in only one dimension.

So, at that point, Normandy had only one course of action. The boys in the basement were roused from their cocaine-addled, opium fueled, Thai lady-boy love fest (the end result of which will likely take a military grade decon team and a decade to clean), slapped on the back of the head, and set to work. What they created is as follows.

Presenting Hasira C. A toned down, slightly more manageable version of Interception vehicle that was key in the apprehension of those wanted speedsters. The primary purpose of this vehicle is modular-design. The vehicle comes with standard equipment, but has mounting points, easily removable panels, and on board computer with an intuitive design.

The body itself is made of Glued Aluminum. It should have been Carbon Fiber, but that would’ve added 20K to the final price. The body panels, however, are made of Carbon Fiber. The front suspension is double-wishbone, while the rear is multilink. There are mounting points for pushrod, should you choose to provide your own.

The powerplant is a 5.8L DOHC 36V V8. With a magnesium block ad Cast Iron heads. VVL and VVT come as standard, with Billet, Titanium and Lightweight forged internals. It comes with a Direct Injection fuel system, with independent throttle bodies and a race intake. As stock, the engine puts out 600 HP and 468 ft-lbs of torque.

However, modular design is the theme. Reprogramming the ECU to increase the VVL and VVT, increase the compression, unlock the 7k rev-limit, and bolting on some after market pipes, will easily net you upwards of 850 HP. Bolting on a couple of turbos and an intercooler, combined with some minor tweaks with the fuel, will easily get you 1200 HP.

A 6-Speed Manual AWD gearbox with a 35/65 diff comes standard, But a straight RWD gearbox is available. The sunroof, wing, front splitter, and hood are all optional extras.

Standard, adaptive springs come as standard, but Acive-sport springs can easily be fitted should you choose.

The interior is sparsely furnished, with easily removable seats, interior panels and steering wheel, so you may add your own personal touch. The infotainment system comes with Bluetooth, GPS and laser / radar guided automated drive.

Hasira comes with an assortment of driving-aids up to and including Traction control, Stability and Launch control. As well as four preset driving modes, and slots for two custom modes.

Carbon Ceramic breaks, and Carbon Fiber rims are available options.

All of this can be yours for a mere $90k

A few questions: How does Kai like Convertibles?

And how does he like these cars?

This is where you have to seriously think about what you’re making.

Would you put a solid axle in anything approaching a sport car ever?

I didn’t expect anybody to consider doing that to the extent that completely forgot to mention it. Don’t put solid axle in the car!! :joy:

1808

Well that was just an example. The real question is, are there situations where less eng. time and PU = less tinkerability? Because realistically that’s the case for solid axle suspension, and I’m wondering if there are other situations that would apply here.

1809

That’s a good question, let me think about it…

…I think solid axle is the sole exception as far as I can tell. I mentioned already that active wing makes little to no impact. The diff is important insofar as Kai can’t play with electric diff. A geared Diff is the most adjustable, yes, but an open one would be more amenable to replacement and upgrade (is my guess). I should qualify that kai has a good jack in his garage but a diff swap is harder to do without a proper rack, so the overall importance is probably, in retrospect, less than it seems.

@titleguy1 Kai isn’t used to open tops, but ultimately doesn’t care either way, as I said to Madrias. I’ll add he’d be ok with a hard top, not so much with a soft top. Both the Mazda and Honda look “ok” , but aside from the bias, Hondas sold outside the US look better than the ones sold inside it :stuck_out_tongue: This one has a fairly serious case of chrome monobrow.

So trailing arm > wishbone > multilink/pushrod in terms of tinkerability?

1812

@strop should I submit my car as soon as I have the main one done or would you be interested in viewing various trims (although with the main review being on a single one) as I already plan on doing this car with multiple trims.

Also I’m building something that fills in a very sparse sub-catergory of cars.

1813

But, but, but…

But the Shelby Cobra has a solid axle! He’s starting to contradict himself as he love’s the performance of the Cobra!
EDIT: (least, I thought it did, I need to check now)

EDIT:
I stand corrected, It was independent transverse mounted leaf spring suspensions on the earlier 260 and 289 equipped ones.

1814

I’ve managed to outperform the Mephisto in some aspects while still having some tinkerability. :smiley: Kai better appreciate the sub 7 minute Green Hell lap in a car he’s able to do a bit of work on.

I’ll either wait closer to the deadline to submit this (and not reveal my hand) or work on a daily car and maybe submit that if I think it’s better… Hmm…

1815

I also chose the larger body to have more passenger space (and hence comfort), but not too much of it. Besides, Kai wouldn’t want something that’s too practical for his tastes, and my car only has four seats anyway, just like yours. However, mine is over $10k cheaper, which means it deliver way more bang for your buck - a boon for Kai if he is forced to pay for the car himself.

And here I thought my entry was good enough. Lol
