907ps at under 7000rpm on Endless-Racing RB26 2771cc engine

This 2771cc Rb26 is no ordanary stroker kit, its a full HKS Hideck drag racing engine, the very same that is found in HKS R33 GTR that ran 7sec passes in the early 2000s. This Dyno results below was the first time endless-r wound up the boost to 2.5kg/cm, the result is an astonishing 907ps (894hp) @ 6564rpm. Trust helped organise the dyno to test their T88-38GK 22cm turbo to get an actual power reading at its 2.5kg/cm limit. While all was going well, suddenly there was a huge bang....Sugino san knew exactly what had happened, we had blown off a boost pipe. (no problem he muttered, prepairing to re-tighten and make another run, however the local police thought otherwise. And I had to say, I would have complained also. The muffler on this car is soo noisy, no back boxes etc and has something like a 6" tail on the end.
The location of the dyno meant that the houses at the rear of the shop could hear everything, and sadly dyno operator and trust called it a day. But still what a power result, in 1000rpm it has a 600hp powerband! and thats wheel hp folks. Dynapac say a correction of 1.20 will give flywheel hp, that makes this car push out 1088ps (1073hp) at the flywheel. Although Sugino san and Trust were shocked at the power, I couldnt help think that any more RPM and this turbo will be into the choke line. Trust previously provided me with turbo data for the T88-38GK and the max PR is 3.5 (which we were at the limit) giving 14.7psi = 1bar. So great reasult, but I am sure the engine needs a bigger turbo...hmmm T100-R shi-yo-ka? :)
