The Death of Speculation



Perception of an unfamiliar product does not equal reality. Although sometimes unaware, many of us have probably been influenced by the opinions of others who don't have all their facts straight. This is a problem that runs amok on internet car forums.

It all starts out innocently in our 10w30 powered corner of cyberspace- Data for a new vehicle is released, and people react to it. Based on that, opinions are formed, lines drawn, sides chosen, and finally, the cannons begin to fire. I’m sad to admit I have partaken in this by sometimes commenting on vehicles I had absolutely zero real life experience with. One such car was the Nissan GT-R.

As any thirty-something who was a product of the Gran Turismo generation, I have an affection for Skylines. Nevermind the fact that I’ve never driven one and have only seen a couple in my life, I love them. They’re highly tunable, twin turbocharged, rev happy inline six cylinder cars with a robust all wheel drive system that demands respect. So imagine my skepticism when the first iteration we see for retail in this country loses its traditional style manual transmission, gains a good degree of heft, and gives up its proven straight 6 for a V6.

Ah, the internet forums were ablaze with words like “pig”, “autotragic”, and “bastardization.” You see, when formulas deviate and don’t conform to what we deem as right, we might sometimes grow arrogant and believe we know better than the engineers behind the scenes. We sometimes might proclaim failure over something that could be sheer brilliance. Different, mind you, but still brilliance. And such is the case with the new GT-R.

I have a friend and fellow car enthusiast who works for Nissan corporate. This lucky schmuck has driven a Nissan GT-R on more than one occasion, so please realize that my name calling has more to do with envy than anything else. Said schmuck morphed immediately into superhero during a fifteen second phone call yesterday when he asked me to come outside, because he was bringing a GT-R by my office!

Fast forward a few minutes, and I’m standing outside my building, waiting for aforementioned chariot to come visit. I didn’t want to look too excited, but some of my friends and co-workers knew what I was up to. So we did not all look like starving, wide eyed pigs in our pen, I placed them like well camouflaged snipers in various places, lookouts where they too could see the GT-R, but not where they would interfere with my turn to roll in the mud.

I heard him before I saw him, the GT-R sounded like an aircraft on final approach. A moment later it arrived, a black on black example that had a mighty curb presence, with all the subtlety of a stealth fighter you might happen to catch a glimpse of while in a military hangar. The yellow Brembos shone out of the rims in stark contrast to the rest of the car. The Bridgestone tires were massive and war torn from serious use. Although the car weighs in at around 3800 pounds, it was smaller to behold than I expected.

My friend offered me a look in the cabin, and I was impressed. I found the materials in the GT-R to be of substantially higher quality than what you would find in an Evo or STI. The seats, the digital dash, and the steering wheel are all quite upmarket in comparison.

And what I thought was the climax of the story turned out to only be the beginning. My friend came along with a couple of his co-workers, and one was a gentleman who had some track time in this car. At this point that I was informed that he would be taking me for a quick ride!

So here is where the fun starts. The torque this engine produces is just senseless. It starts pulling relatively low in the powerband and then never relents. Weight is much less of a negative factor when you have ample power to offset it.

One thing that a person who is new to the GT-R will notice right away is the transmission. This is an unapologetic racecar with a transmission designed for performance first and comfort last. The shifts are lightning fast, often violent, and you find yourself already rocketing forward in the next gear before you could have completed an upshift in a traditional manual car. I have never been a fan of these newer style transmissions because they isolate the driver from the full experience of man and machine interface, but there is no denying that they are substantially faster. I guess that Nissan engineers asked their product planners if they want to have a slower driver actuated clutch or they just want to go fast. Voila. We got the racecar transmission. Don’t pout, it is awesome and perfect in this application.

This car handles well for a big car, but the real beauty is the point and squirt nature it has. It goes something like this: Setup for corner, enter corner, stay on line, stand on throttle earlier than you would dare in most other cars, blast toward horizon like freaking rocket. This car’s balance is not upset by its abrupt power. It just gets there faster… A whole lot faster than you’d think physics dictates it should.

And so my ride came to an end as fast as it began, but left me with a real opinion to replace months of internet bile. And I am left to conclude that the GT-R is an awesome, serious track car that is not to be trifled with, an affordable supercar that can slay giants more than twice its price. I'll even go on record as saying its the best car I've ever ridden in. Godzilla is finally here in the States, and it hasn’t been watered down at all.

Project 135i- Engine performance




With a smidge over 1200 miles on the clock, the Vishnu PROcede installed, and more seat time, I'm ready to talk about the performance of the 1series.

The engine is a peach. As you can see from the graph, power and torque are up globally. Low end torque is softer than my 335i, but the overall mapping is much nicer across the board. At wide open throttle tip in, it just pulls harder and harder to the point that getting in trouble in a hurry would not be an issue. The tires will lose traction and rip on the 1-2 upshift, and again on the 2-3.

There is some concern about the high RPM puke-n-die. I spoke with Dustin at Vishnu about this, and he said it is intentional for hot air correction. I've revved it just beyond 6500 on the street, and I have not felt it exhibit this behavior at all. Looking at the shape of the dyno graph, this power reduction would be really easy to detect.

I'm satisfied with these numbers, particularly since they were attained with only 860 miles on the car. With 200 pounds less weight, nearly 20whp more, less mods, and a superior area under the curve, this car would humiliate my poor little old X in a contest of speed.

Project update 12/22:




Intakes and corresponding mapping picked up a ton of power on the dyno.

Project 135i- Initial review



I've had a few requests for a 135i review. I can accomodate that, but only partially, because the engine isn't fully broken in yet. So far, I haven't spun it higher than 4500rpm. I have a Vishnu PROcede en route and dyno time scheduled, so the power portion of this review will have to be saved for a slightly later date.

The first thing that struck me about the 1 series was its fit and finish. This car was screwed together much better than the Evo it replaced. It also has higher quality components than the Evo: Instruments, dash, seats, body panels, headlights, paint, etc. This lessens somewhat when compared to my 335i. While the instruments and seats are the same, the dash plastics and materials are visibly downmarket from the 3 series. I guess they have to have a few solid reasons to justify the price difference.

I am loving this transmission. The notchy shifter in the Evo X was one step from making me go completely postal; the shifter in this car is like butter. Slow standing starts on an incline couldn't be easier thanks to the hill holder feature, which also helps to minimize clutch wear. The gearing has allowed me to return better fuel economy than the Evo, even with two extra cylinders and another liter of displacement. Since the powerband is wide, the somewhat taller gears are not a problem.

This car is more nervous than an E90. Again, I haven't really had the chance to really put it through its paces, but it has less poise than the E90. The wheelbase is suspect, as well as the small front tires. The car can go from understeer to oversteer with throttle lift, but it pushes way more than I would like. This is not to say the car does not handle well, but its a pretty convincing downgrade when coming out of an SAWC Evo X.

The drive by wire on this car is a bit laggy. The engine and turbochargers are NOT laggy, building boost strongly from 1400rpm, but I never thought I'd say the throttle mapping on a Mitsubishi would be so superior to a BMW.

The powerband of the BMW's N54 engine is lucious. I have awesome passing power in sixth gear from low speeds, something you'll never see in a turbo four. With this car weighing in at 200 pounds less than my Evo X or my 335i, its gonna be downright nasty-fast with the PROcede installed.

The runflat tires are garbage. This is evident when you hit a pothole or especially an elevation imperfection. There's one such spot on the Interstate I hit going home everyday that makes me feel like I am being uprooted when I strike it. Really bad.

The open differential is cheese, and I'm sure I'll notice that more when a few miles pile on.

This car shines at just being a great vehicle. Its quiet as a church mouse, its comfortable, the leather is of high quality, and the ride is fine if you aren't testing the runflats over bumps. The standard hifi radio is even good, even though I had my heart set on the premium unit. I upgraded the tweeters from some leftover Focal Polyglass componets, and they sound brilliant. Even at 25x4 on the main speakers and 40x2 on the subs, it seems to have plenty of power.

Although this review is a mixed bag, I think this car is a way better canvas for performance than a 335i. It is a couple hundred pounds lighter, after all. The brakes are just massive, and should be amazing with better pads and a good aftermarket fluid. The understeer could be helped with wider front wheels and tires to match the sizes of the rear. A rear swaybar and a hot alignment should help a ton as well. None of this stuff is expensive. All that with the aforementioned PROcede should make this one heck of a run ride. Add all that in with the fact its a RWD car with an almost 50:50 weight distribution, and things are looking good.

As a total package, I have absolutely no regrets going from the Evo to this car.

More coming soon...

Project Evo X- The trouble with 10

As many things that are outstanding with the Evo X, there are some negative issues that are worth mentioning:


1)Weight. This is the Achilles heel of this platform. A two liter four cylinder engine is just too small of a powerplant to move around a car that weighs 3500 pounds. For an Evo X to be able to accelerate like an Evo IX, it needs more power, to the tune of 25whp. With the stock turbo on this car, there is just not as much potential in the forward thrust department unless you have a larger financial outlay for modifications.

2)Transmission. I’m not going to mince words, the gearbox in this car is not really good. It is compromised with a shorter final drive than the IX to make the extra weight a bit less obvious. The downside of that is poor fuel economy and high RPM on the interstate, making for loud and buzzy travel, particularly with an aftermarket exhaust. The other thing about this transmission that is unacceptable is how notchy some of them are when upshifting to second and third gear in normal driving… It was a borderline gear grind in my first X, but my second one is a lot better.

3)Paint. The overall shape of the sides of the X are concaved like lots of modern cars, but this one allowed tons of pebbles and road debris from the front tires to spray the sideskirts and rear sides, causing several small paint nicks down to primer. Mud flaps in the front and a 3M clear repellant skin were the best workarounds for this. I have Rally Armor flaps only on my current X, and it has seen no damage. My prior X looked sandblasted on the side from the rock spray without these flaps.

4)Interior rattles. I don't expect this out of a Japanese car, especially a new one. There is a glove box door rattle (really common in these), an ash tray rattle, and door rattles.

Project Evo VIII- History


The first Lancer Evolution for sale in the USA was the Evo VIII, and I was an early adopter. Having previously owned a second generation turbo Eclipse, I knew the potential of this engine.

Back then, I had a 2002 WRX with modest upgrades, including an ihi vf30 turbocharger. A lot of us had jumped from Hondas into the WRX camp. When it was announced that Mitsubishi was finally bringing the Evo here, we were buzzing with endless speculation, most of it guesswork based on absolutely nothing. The general consensus among our group was that the car would be dumbed down for US consumption. One of the leading thoughts was that the US Evo would be neutered of its 16G and instead receive a carryover T25 turbo from the Eclipse.

Boy, were we dead wrong. The VIII with only a few negative changes hit the US with a vengeance. I knew I would probably do something stupid if I saw one, and avoided Mitsubishi dealerships altogether for a couple of weeks. This did not last. I went to our local dealership to see the car in person and took a test drive. Within ten seconds behind the wheel, my WRX morphed from a tuner wagon into a relic from an ancient civilization in my mind. The Evo didn't have an impossible to service boxer engine. Instead, it had a proper inline engine, razor precise steering, gearing that wasn't hijacked from a truck, a huge stock turbocharger, and bright red Brembo brakes that looked like they could stop a train.

Shortly later, I went to another Mitsubishi dealership and promptly traded my WRX in on the Tarmac Black Evo VIII you see here. I'll never forget the homecoming, pulling it into my garage the first time, and dragging my wife outside to see.

"What do you think?", I asked excitedly.
"Man, ricer wing!", she replied casually.

Every man should be so lucky to have a woman like this in his corner.

Two days later I brought it to work for the first time. One of my co-workers and friends who knows and shares my automotive tastes saw it in the parking lot and ran upstairs to tell me: "Dude... Black turbo Mitsubishi. Brembos, rims, hood vent... In our back parking lot. Did you see it?!?"

"I'm pretty sure the keys are in my pocket.", I replied.

And so began my time with Evos. Its been a long ride, and I have miles of stories to tell.
