Site is up now. www.syntectopshop.com also you can look at the other engines that are in the competition. SP engineerings monster! 1000hp RB26DETT

URL Fixed EDIT...Sorry guys it has been a rough week.

 

Thanks! You're link above needs some work though...

Let's keep this between us so that our odds of winning increase.

 

Yea I think they took down the site shhhhh

Chris

 

I always thought these were some insane N/A setups. They even give a breakdown on parts.

I personally want to do something like this ^ when I hit 100k.

Yeah it will be just between us....hell I'd even take SP RB engine and work the engine in my Z..Lol.

 

The All-Motor VQ35DE - Top Shop Challenge

Ever since we had the opportunity to drive Endless Racing's Z Car Challenge 400hp naturally aspirated (NA) Z in Japan, building the same engine here has topped our list of geek obsessions. The only reason we never went ahead with it was because Project Z had already been committed for turbocharged power and the cost of building such a fully prepped engine gets pretty outrageous, not to mention an engine like this only drinks 100 octane. But automotive karma works in strange ways.

Castrol invited us to face off against our sister magazines (Super Street, Modified, Eurotuner, Import Tuner, Turbo, Lowrider) by teaming up with a shop of our choice to build a no compromise engine in its Castrol Syntec Top Shop challenge. The competition would be based on peak horsepower and torque per displacement (displacement is multiplied by 2 for anything with forced induction), total horsepower under the curve, a 30 minute endurance death match (all tests will be administered on an engine dyno), and a engineering challenge to impress a panel of engine guru judges. All of which sounds suspiciously like our USCC rules.

While everyone else might be building a dyno queen engine, we're looking to build something real world that might one day end up in some lucky raffle winning schmuck's engine bay (the winning engine will be given away to one lucky member of the public).

Picking a naturally aspirated engine to go into a horsepower battle with turbo engines might not sound like the smartest thing to do, until you look at our rules and consider real world performance. For example, if we chose to build a 3.0-liter Supra motor targeted at 1000 bhp, the numbers would break down to around 166bhp/liter since a turbo motor has it's displacement multiplied by two. A 5.7-liter small block would really suffer even at a wishful 1500bhp. That would land it somewhere around 131bhp/liter, just a little more than Honda's out of the box S2000 engine.

Even if we can't make the most power per displacement with a NA VQ, there's another side of the equation, power delivery or area under the curve. If you've ever seen the power curve of a big turbo, small displacement 1000 hp car, it's essentially useless until the last 1000 rpm and undriveable, regardless of the engine speed. For most of the power band, the engine will be struggling to make a fraction of its peak power until the monster turbo, needed to flow this amount of air, finally spools and skyrockets the power at an uncontrollable rate. Do the math and the area under the power spike won't compare to the steady power coming from a NA engine.

The Engine and the shop
So we decided on Nissan's VQ35DE as our base engine platform. It's the ideal combination of displacement, rpm, fundamental design and flow capabilities, not to mention a respectable amount of low end torque. Add on the 100 octane gas that everyone will be using for the competition and we'll be able to raise the stock compression ratio to a respectable race engine standard. Our aim is to build an easily replicated, street usable, 400bhp naturally aspirated VQ35DE. Several respectable tuners like Tomei, Nismo, Cosworth and Jun Auto already have extensive research and racing programs based around the VQ.

When it came down to picking a shop among the notable VQ tuners, we decided on Cosworth Engineering for several reasons. Namely, they spoke English (even though with a strange accent at times), the US headquarters was right in our back yard here in Southern California, most of the parts we would be using in the build are sold off-the-shelf and, mostly, because few organizations have the engineering capabilities, expertise, and experience to rival Cosworth.

I like that Cosworth's blog reports preliminary testing of some new NA cams on a 11:1 3.5L engine are making 370hp on an engine dyno, and that their stroker VQ should surpass 400hp. I especially like the part about all the components developed for this engine being available for purchase.

They should be able to hit 400 bhp without much effort if they can flow enough air...which I think they can using their intake manifold and the air supply from the engine dyno. My car's best dyno was 316 rwhp which I would estimate to be around 370 bhp and that is with some rather mild 272 degree cams. Using bigger cams and enough intake flow I'm sure they can reach their goal.

 

Wow.....that was painful to listen to his engrish.

 

I personally just want to see what they do to squeeze the max HP out of the VQ.

 

They finished in 6th place out of 7 contenders. I wouldn't blame Cosworth though...SCC brought an endurance motor to a dyno challenge.

Results:
360whp/290wtq
(438hp/359tq crank)

 

^link?

 

The results were just published in print so they typically take a month to make it online.
