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).
