Two huge builds are reaching tipping points in the GT-R world this week with big news from two prominent tuners that the 1000awhp barrier has been effectively reached. In one case it’s even been poked with a sharp stick.

First up from Switzer was the announcement that their R1K prototype build has reeled off a 1005awhp dyno pull at 32 – 34.5 psi of boost running VP C16 fuel. To get this level of power the R1K package will feature custom manifolds, and a pair of big Garret watercooled turbochargers fitted with external wastegates. Switzer are also quick to point out that this tune is not right on the ragged edge. Conservative timing and boost settings are deliberately chosen for durability.

Hot on the heels of the R1K update, SP Engineering announced that their SPE1000 build has bumped its head against the limit of it’s ID 1000cc injectors at 997awhp (886 lb/ft of torque). They ran 30psi of boost for the pull on C16 fuel. ID 2000cc injectors are due to be fitted shortly to sort that and back on the dyno to make it an official round 1000awhp … or more…

So yes, it’s huge news and it won’t stop coming any time soon with AMS set to have their own 1000whp Alpha GT-R demons on the dyno in the not too distant future.

Right now it’s a little too close to call who will win down at the track and that really is where the where the winner will be decided. Can’t wait to see it!
