The search for +1000 whp RB26DETT

Hi chaps! Remeber this beast? (The +1033 hp RB26DETT Skyline from Finland)

So, the owner had some more Dyno sessions. The car did fine, it held the boost time after time, the engine got some cam adjustments done for different torque setups etc.


After few dozen the dyno sessions the engine was opened and analysed for wear & tear. It was fine, everything as it should be.

So the engine is going for some more boost, as the latest dyno figures were disappointing for the owner – you might think, what the hell… Well the figures were just under 1000 Wheel Horsepower, 996,6 whp to be exact. He wants +1000 whp from 2,6 litre engine, hah.

The new plan is to run it at 2.5 - 2.8 bar boost. The previously used 2.3 bar boost killed the Nismo twin plate clutch, a new HKS 3-plate sintered version is swapped for the new challenge. The pressure bearing for that set up is custom made by Valtonen Motorsport.
The previously used Panta fuel was changed to VP Q16 fuel (120 oct).

Other additional goodies are the new carbon doors, boot lid, bonnet, front fenders, front bumper, mask and OEM style rear spoiler. The weight saving is going to be huge.
The new Cusco 1-way diff found it’s place at he front, so did the new 1.5-way LSD at the rear. This should help with the grip problems.

And like any hiperformance car – they should have in car entertainment. Period. The owner choose Alpines finest to keep him happy when the engine shoots it self to the million pieces – nice theory. He's comment was: "This way you’re always happy in you’re Skyline".

Here's the final Dyno sheet & figures. Pretty damn impressive!



Max HP at the wheels!!! (Wheel Horsepower)
733,9 kW (DIN kW) = 996,6 whp (DIN hp) = 982,97 whp (SAE hp).

Max Torque at the wheels
954,9 Nm (DIN Nm) = 703,54 lbf ft (Pound Feet) = 97,25 kgf m (Kilogram Meters).

The search for +1000 whp RB26DETT continues :D

The power of Holset – 1033 hp

Ok chaps,

So we live in Finland. In a land where winter is 8 months of year – it snows even during summer, hah.

During those long snowy winter months we hit our stupid heads together to create something seriously ill shit, like this.


In the belly of this satin black beast lies something truly insane…

How do you get 1033 horsepowers out of Nissan’s RB26DETT engine (yes, 2,6 liters)!?!

"– Well, hit the boost to 2,3 bar and a drop in a pair of Holset HY35 turbos."

To keep things happy inside the new power plant, a counterweighted and balanced R33 GT-R crank is the foundation of the bottom end. Also CP-pistons were added with Eagle H-beam conrods. Still running oem head bolts.
Upstairs has parts like, Tomei Poncams 282 with 12.8mm lift and Tomei cam pulleys. The other belts have Greddy pulleys. The Greddy plenum is feeding air to the head witch is fully ported by JR-Tehokansi. The 1,6 mm head gasket is by Tomei. To feed this beast, a Hestec Ecu is used (Tuned by Seppo Harinen), a heafty loads of boost is offered by Hestec boost controller. To keep juices flowing a set of two Walbro and two Bosch Motorsport 044 fuel pumps are used with 18 mm fuel lines. The Sard fuel rail with Aeromotive’s fuel pressure regulator will keep the 1000 cc MSD injectors happy. Sparks are delivered by Bosch Motorsport 034 ignition coils.



The 100 mm cooler has company of Koyo radiator, other coolers are custom jobbies as well, like the relocated Mocal oil cooler and totally removed/relocated water circulation. Oil and water are pushed with Nismo’s high performance pumps.
To handle all that torque – a 989,6 Nm to be exact, a Nismo Twin Plate clutch is barely taking it – it’s starting to slip so the boost is kept where is it at now.
Exahaust is a custom 4” job. With those monster Holset HY35’s, is a pair of Tial 60 mm wastegates and Tial blow-off valve.





The additional goodies are inside the cockpit. The Defi meters for water temp, intake temp and oil press. Greddy’s for boost, oil press, oil temp and egt. Vems wideband meters for both of the turbos. You might noticed that there were two oil press meters, well the oil press is metered at two different points.



To keep all the power on the track, a set of Mickey Thompson 275/40/17 street radials are used. For the street use (yes, this car has license plates) 275/30/20 TSW’s are under the arches.
Ride height is taken care by K-Sport suspension and the handling is improved by poly bushes all around. Safety cage is an improvement as well. The brakes are under upgrade at the moment – something big with loads of force to stop this beast.



Oh, yes and that Dyno sheet.



All measured with Inertia Dynamometer (at Special Tuning Harinen).

@ 2.3 bar (max 8800 rpm)
• 1033 hp (DIN) [759,77 kW] / 1018.85 hp (SAE) – Panta 115 oct fuel
• 989.6 Nm / 100.88 Kgf / 729.36 lbf

@ 1,95 bar
• 890 hp (DIN) [654.60 kW] / 877.83 hp (SAE) – Shell V-Power pump fuel.
• 820 Nm / 83.59 Kgf / 604.72 lbf

And for those thinking "one lucky dyno queen shoot"... the cars been on the dyno close to 50 runs - more than some drag cars can take. Every time pulling figures like this.

More to come, carbon – alots of carbon!

-----

Update! (the dyno sheet is from the first runs, running a limiter at < 8000 rpm - now it's past 9000 rpm).

Alien2nrs in japan - Car shop day 3

Are you ready for this? The car shop day 3!

Me & Juhis headed to Machida City, located in the western part of the greater metropolis of Tokyo. Home of the greatest tuning shops...


We had to take 5 metros & Trains to get there...

First stop was at Monster Sport.
Very clean & professional shop. Famous of their Suzuki Escudo Pikes Peak car.



This Evo is called Maziora V2 Champ RS - it was also in TAS.


Show room had Evo 6 & Sti.


On the yard was this beautiful Tommi Mäkinen Evo 6.


In the shop they had their Rally Evo...


...lots of Monster parts, Race Engines etc...

Next stop was my favorite - Bee*R (Bee Racing).


The shop.


Toyota Athlete Crown, a D1 car driven by Masayoshi Tokita.

The D1 Crown has a 2JZGTE engine from a Toyota Aristo. The 2JZ is stroked to 3.4L using HKS kit. It has HKS single T04Z turbine kit, Holinger sequential transmission with an ORC clutch and a TRD LSD. The car is pushing around 700hp.


Some customer cars as well, like the R34 Nismo S-tune and R32 GT-R.


Bee*R's famous charged S15...


...SR with Super Charger & Turbo!


D1 B324R, driven by Tsuyoshi Tezuka.


GTROC sticker :)


Yokomo's B324R RC-drifter...


The RC-drifters detail is very accurate. GTROC should be very proud of this!


An other B324R drifter. You can spot the difference between the cars, look at the mirrors ;)


Bee*R B324R type-II, non widebody. Using R34 hood.


With this kit, you can also use OEM R34 bumper.


This BNR32 belongs to certain JGTC driver. +800 bhp!


The apprentice and the Master Imai-san.

Used & Outlet - Wheel Proshop Yokohama Garage-kan was next on the line.

As the name says, it's a shop for used wheels. Representing the quality brands.


The front yard looked very promising...


... and it didn't let us down.


Gram Lights.


Trafficstar Riverside - SFR.


More wheels on the yard...

That's for the wheels for now.

It was time to go where few have gone before.


The street sign giving up some hints.


The Tomei HQ & pro shop.

After the office tour it was time to see the research & development line.


VQ35 cams, heads, ect...


New Evo turbos, custom built by Tomei.


Engine dyno room nr 1. (Tomei has 2 of them).

The production line...


The camshaft master. This man is the only man who makes cams at Tomei.
He's been making them since '68! We saw cams for new Lambos, Nismo, etc.


These Titanium headers where just mockup models :o


Test bench BNR32.


Tons of goodies to ship around the world.


Fairlady 350Z was still sporting the 3.5L engine. Other cars in the same Z masters -series where running the 3,8L. This car was still hard to beat. It's all about the power band - not the horsepower said Tomei.

Last but no least we hit the aftermarket & used parts paradise - The UP-Garage!


Wheels waiting to get checked in.


Toyota Mark II sporting Work Emotion XT7's.


SSR - Star Formula!
