Adamgp's Shelby Series 1 got high marks from me during Middleweight. Let's see how things go with this Heavyweight entry.
Speed
Top Speed:
149.3 mph
The engine's an all-aluminum
487 cubic-inch monster, which means (as we all know) lotso torque. Acceleration in 2nd or 3rd gear is a piece of cake, from just about any rpms over 2,000. But when comparing the engine to its gearmate, there are some question marks that are raised.
Honestly, I HATE the gearbox in this car. It keeps us shifting from 2nd to 6th gear (if we're to be staying near peak power, which is at
5,200 rpms). What I hate about it is it's simply too busy. It doesn't focus on the V10's torque enough. Instead, it has us dipping and blipping thru, like quick splashes into a wading pool. However, I'm not factoring my hatred into scoring. I'd prefer to keep this car in gear longer (especially 4th and 5th), but I'm not sure if there would be a true advantage by doing so.
6th (in my opinion) shouldn't even become an option at this track...it should be reserved for the super-long straights of Route 246, Route 5, Grand Valley, and the Nurb.
I would have prefered a taller 5th gear. I would have preferred to keep torque propelling the car, keeping that tach needle in the frying pan a bit longer in 5th, rather than needing that upshift into 6th. But, I didn't do a seperate retest with taller gears, because I just wanna get
Heavyweight done, and so does everyone else I'm sure. 💡
Now the good thing? There's plenty of flexibility to be had with gearing. Once again, we can leave tight areas in 2nd, or we can use 3rd. Peak torque officially starts at
3,700 rpms, but
useful torque starts well before this...more like 2,700. I could safely make eXtReMe torque grabs in 3rd gear from here. In fact, on what could have been my best lap, I made a mistake in Turn 6 and didn't shift down far enough, although I did turn-in nice and strong. Didn't matter, the Viper still maintained a workable lead over the ghost, walking from this turn in 3rd gear without a hitch. If I hadn't lost it in the upcoming esses, perhaps this would have become my Best Lap. Oh well..
The flexibility doesn't end there. Even tho (technically) an upshift into 6th is needed down the longest straight, in practice, I could keep it in 5th. Now, I didn't like to do this. The GTS gets too far from its peak, and starts
redlining. Speed drops off quick once you're on the down side of the horsepower slope, but it's
useful to stay in 5th since the RPM limit isn't met. It's useful...but actually,
it's better to upshift into 6th than stay in 5th down the longest straight. Confusing, so let me try to explain further...
** There was a lap during which I was rolling down Motegi's first straight. The ghost and I were exactly nose-on-nose. I chose to leave the car in 5th, while the ghost shifted up to 6th. I nosed ever-so-slightly ahead of the ghost since I didn't upshift, HOWEVER,
the ghost soon nosed slightly ahead of me, even tho I had kept full-throttle. But how can this be?
Well during the ghost's upshift, it lost a small bit of momentum, and I got ahead. But as the V10 motor pushes towards
redline, horsepower starts to vanish, and the Viper doesn't build speed as fast. Since the ghost is now sucessfully running thru its peak power area again (4,900 to 5,500 rpms), it nosed slightly ahead of me, even in a higher gear!
It just goes to show, there's alot of capability in this V10, if you shift
early. I'd typically shift about 500 rpms before
redline. No0bs usually don't seem to understand this stuff, and sometimes they think they're getting the best performance from an engine like the Viper's, even with an automatic tranny. They sometimes think there's no difference between MT and AT...that automatics are actually better, since they shift for you, which means all you gotta do is concentrate on steering, fuel, and braking.
No...you gotta shift early with an engine like this; which means use MT instead of AT.
Anyways, back on topic.
Rolling between turns 1 and 2, the engine again starts
redlining in 3rd. Thankfully, the RPM limit isn't met here. Luckily. There's a couple other spots where one has flexibility with keeping the car in 5th (or 4th), rather than needing an upshift, so there's some points gained for this.
So far as down-low acceleration goes, there's plenty of
traction, thanks to those massive 335 width tires and the weight of the transaxle between those rear axles. 👍
Compared to others in the Middleweight, Adam's Viper is rating towards the top, but hasn't got either the best Lap Time or the highest Top Speed.

Handling
I don't think Dodge named this car "Viper" just for something intimidating to call it; I think they realized just how
snake-like it can be in turns. The way Dodge Vipers coil and slip around as they're driven feels very snake-like at times.
The first and most-important thing to learn first when driving this one is to
brake early. Everything else falls into place if you just remember this rule: BRAKE....EARLY. Learn it. LIVE it.
The greatest fault with this car are its brakes, no doubt about it. Again, with these default Muscle Car Garages front brake settings.
Grrrrr...
I may have been able to make solid
1:21's, instead of the 1:22.6xx I had settled for. But the good news:
get your braking done nice and early, and everything else falls into place. The MC Viper GTS lends a helping hand too, since it trail-brakes to a limited degree. 👍
Here's a tip. Braking usually can start
before the skid marks on the track into Turns 1, 6, and 8. In other words, as you approach the skids which lead up to any of these Motegi corners, start braking just before these marks begin. Into Turn 2, the backwards-bend, and the final hairpin, I could brake just where the skid marks start, instead of a hair earlier.
This one turns-in gracefully, and with a very solid feel. The steering works. It's definately useful, but it's also
very heavy. You gotta
prepare as you turn-in. On the other hand, the front-end is quite predictable. There isn't too much grabbing, and it's also easy to find where the land of understeer starts so you can avoid it. There's a safe window in-between grabbing and understeer, which I found easy to work with lap after lap.
The Muscle Car Viper isn't truely inflexible (so far as steering-in goes), but neither does it have a true sports-car feel. The Viper GTS is
miles and miles away from the Miatas, S2000s, and Solstices of this world, folks! While the front-end's ability to steer-in is useful, it is a tad too slow for
hot-lapping at Twin Ring East.
But if you find that racing line, all is good; there is some variation and play involved once you discover it. There is a window. You're
not just stuck with one solid racing line like you are with Jonn's Mazdaspeed, even when pushing the Viper to newer and newer heights. Just make sure you've heated up those brake rotors first. 💡
What else is there...
lift-off oversteer. The GTS lifts-off about as much as it trail-brakes; which is just enough to be useful, but not over-excessively. I'm glad the limited-slip's Initial and Decel ratings are at minimum....I think both these settings allow the
Muscle Car Garages GTS what flexibility it has. 👍
And when powering out of corners, there's plenty of traction (like I mentioned above in the Speed section), and the car throttlesteers if you want it to. Again, it doesn't throttlesteer excessively, but just enough to be useful. I found that there's lots of racing lines that this car can use
out of both of Motegi's hairpins. But when powering out of the esses portions, there's some throttlesteer, but there's also the risk of understeer (or at least, not enough of a steering angle) which can show up. Launching this car out of esses therefore takes a bit more care than launching out of hairpins.
Over the funble strips, the Viper rarely gets upset, partially because it's a heavier car with wings, partially since it's got a massive footprint (huge tires), and partially because Adamgp didn't set those sway bars and coils too strong. The times when I found the rumble strips to be annoying were the times when I wasn't in the racing line I wanted.
But it's the little things (other than those soapy brakes)that also hurt the GTS, even when the racing line is 100% solid. The moments (which feels like an entire week going by) between letting-off the brakes, and true lift-off taking over.
...The moment (as the Viper finally locks into its groove) where you can't do ANYTHING with the gas. Don't even
look at it! Even when stomping on the gas after a good wait, there's still not a guarantee there will be enough throttlesteer to carry you out without rolling over a rumble strip or even some
grass. But it's also possible to
find the exact moment to let the Viper strike. Once you find it, it's alot easier to employ than in some other Heavyweights.
So the car is predictable. It's got
some flexibility once you start to nail it. But also muscle-car worthy brakes, heavy steering. Be patient, and the car works with you (while pushing harder).

Versatility
Warming up, and driving for fun, there's LOTS of versatility to be had, even while punishing the BATTLE MONSTER. When I did a Family Cup race at Twin Ring East, I tried a bunch of different difficulty ratings: from +3 to +10.
Oddly, the +3 race felt about as challenging as the +10.
Anyways, the point is clear--it didn't matter where I set the Difficulty slider, the Viper can conquer all. My main competition ranged from Pagnanis, to Saleens, to the Honda NSX-R Prototype. When racing the
Muscle Car Viper GTS (rather than just driving it on an empty track), it becomes even clearer where its true plusses and minuses are.
The front-end is limited while braking (we need a long distance to slow), BUT the Viper lets us trail-brake to a degree. 👍 So while racing, I found I could trample some Ai in every category EXCEPT braking-in, unless the Ai driver happened to really suck at braking, and started even earlier than I did.
When leaving corners (driving casually on an empty track), there's alot of experimenting to be discovered out of hairpins, and to a lesser degree out of the esses. From hairpins, we have plenty of moments when the rear-end just gets
slightly drifty....you can feel the sideways motion...you're countersteering to correct this, yet you maintain the drift a little longer anyways, just cuz you can.
During these moments, there's
hardly any tire-smoke or squeal! Fun times.
The
Muscle Car Garage Viper GTS feels confident passing cars while throttling-out on the inside
or the outside (assuming there's enough path on the outside of the track to save the Viper from some
grass. During these moments, if the path you need isn't immediately accessable, you can possibly explore a different path on-the-spot, assuming there's no brain-dead Ai driver ahead of you. Like I said, the main thing that really hurts are those "muscle car" brakes.
For instance, as I was leaving a corner too
hot out of 2nd gear, I could upshift into 3rd, but let the car coast a moment. I didn't get all I could get from 2nd because I had upshifted earlier than I normally would have--but once the front-end stops pushing, I could use the extra time I had needed to shift up into 3rd more efficiently, if that makes any sense. ...Basically, it's better than exiting in 2nd, encountering understeer, backing off the throttle till the Viper orients itself, but then powering back out using 2nd again. By shifting into 3rd early, I've saved a bit of time for a later upshift. Which doesn't matter in the long run since the V10 feels confident powering-out in 3rd.
When going for Best Lap, the MC Viper GTS only keeps about 10% of its original versatility, so here's where the score gets hurt an extra point. On the other hand, there
is still some versatility left, as well as predictability in keeping those lap times consistent, so you get that point back. BRAKE EARLY, is the main rule.
Overall, things are looking good, but there's still some things hurting the score. Mainly those brakes.

Car versus Battle Monster
It took me a couple laps to bring the MONSTER down...and let the Viper savor some roasted Skyline meat.
The first lap was all bumbles and scrambles, as I struggled to figure out where and when to brake & turn-in and stuff. In the second lap, I decided just to brake early
everywhere, and it worked. The GTR was now history.

---------------------------------------------------------------------
Improvement over Stock
Power between a stock Viper and the Muscle Cars version is just 8 horses in difference, which really makes for a truer comparison between stock and tuned in certain ways; especially so far as braking and powering out are concerned, since both cars have the ability to tap approximately the same well.
One can't ignore there are other forces at work, though. Especially when comparing lap times between stock and tuned. With the tuned car, I was making consistent
1:23's with speed running towards 147+ mph down Motegi's longest straight...1:22's when I nailed it better. In the stock GTS, it was
1:29's, with Top Speed at about 141+. So
something has been improved here.
Gearing is the first obvious improvement. The tuned Viper assumes
all of those gears (except 1st) come into use. As demonstrated above, even 6th is required down Motegi's longest straight. A stock GTS needs just gears 2 thru 4. Although my heart prefers the stock box (love them torque grabs), it IS too tall for Twin Ring. So that's the first improvement. There are weight reductions, too. 👍 All 3 stages. I'm awarding 2 points for this, rather than one, since there's lots weight removed:
574 pounds of it.
The stock GTS has staggeringly BAD brakes...really awful. All my brake distances needed to be even longer than in the
Muscle Car GTS, which slows down at little better, but still could use improvement. It's the
wings that really help the tuned car. I'm thinking that wing kit (the airflow resistance that is being created by having wings) helps slow the car more than Adamgp's actual brake settings. Both cars trail-brake to a limited degree, so no improvement possible there.
There are some improvements in the tuned version's cornering behavior, which is gonna help Adam alot.
I noticed both cars turn-in while braking, but the stock version wallows and dips alot more; in ways that
aren't helpful. All this extra movement creates small wobbles in our racing line, which doesn't matter when you're driving casually, but when Best Lap is being hunted, you'll want your Viper's chassis/body relationship to feel more controlled. I was thinking that the stock version might grab into corners better, but this turns out NOT to be the case. Both cars have about the same amount of front-end grabbing once those brakes are off. The tuned version actually understeers a little
less mid-corner, matter of fact; courtesy of the maxed spoiler up front. That was a smart move putting the Initial and Decel settings at minimum, Adam; letting the Viper you tuned keep what flexibility it has.
The Tuned version is a little more affected by rumble strips than the stock one, but doesn't get bothered enough for me to remove a point. While powering-out, both cars have loads of traction, but the tuned version displays a little less understeer than the stock one--odd, since the stock car hasn't got an aftermarket limited-slip installed; so it must be something in Adam's tuning that's helping here. Adam's remake locks-in with mild to moderate throttlesteer which feels more confident. 👍
So lots of improvements here, some expected, and some unexpected.
