    • RB N54 GF (Game Finisher) turbos set pump gas 93 octane record at 583 whp and 681 whp on E85

      Great results here for the RB GF (Game Finisher) N54 hybrid turbochargers. You will be hard pressed to find better hybrid results as the 93 octane 25 psi figure shows 582.9 horsepower to the wheels which to BimmerBoost's knowledge is the N54 pump gas power record.

        Nice results so far!

        Plan on pushing these a bit further?? Seems like they have a little more left in them.

        E85- 681 wHP, impressive +99 wHP gain with only additional +2psi boost!! E85 rocks.

        Yeah definitely more left in them. That being said, no I do not plan on pushing any further. It is a stock motor car so pushing it a bit far as is. I do plan upgrading to a larger IC, a aftermarket fuel pressure regulator/return line, and maybe a aftermarket exhaust.

        Kick ass results, power curve looks amazing, car must be a handful. Glad to see some "Average Joe" 3rd party results, too, not an often occurrence with results like these and as you stated there is no reason why anyone could not get the same results as you all day everyday. That 93 dyno too, wow, it is not often do you see figures like that, has there ever been any comparison to that in the platforms history?

        As for pushing things further we do suspect at his current E85 boost targets that the pre-turbine backpressure is still quite reasonable with these seriously upgraded housings- possibly where other smaller housing setups are in the 20psi range for example. This said it could be that the BP ratio looks very well even north of 30psi, but we really need to get that data before we speculate that much. As backpressure is a killer of engines and turbos, in the interim we had advised a good place to be would be is where he is at now if he wants to play it safe. Can not emphasize enough how far away these results are from "Glory pulls" filled with bunk information and tremendous aggression for marketing purposes, which is all something this market has been riddled with for years.

        Lastly we rate these turbos in the 650-700whp range so happy to see he easily got there on his own with a 1st or 2nd revision tune and basic supporting mods and completely stock engine the first time out. Once we get some RPM and BP data on these units we can determine just how hard they are being worked at these ranges, alongside power output our desire to keep things efficient so the units last, there is no point in making turbos that make good power once and then blow up the next day.

        Helix seems to be still working. Certainly would upgrade the cooling system first then design the new intercooler around that. No Setrab oil cooler? Surprised you could not get enough gasoline through the DI system. I wonder what the limit is without PI?

        Well done!

        Not sure if any ST cars have ever bested these RB GF pump only results, but it doesn't seem that ANY twin setup (even a FULL STAGE 3 GARRETT GTX on a Vendor car) couldn't even match them thus far. Good work blaster3500 and congrats on the record (relatively low effort one that that!).

        Thanks! Helix is doing well for its size but I get a decent IAT on multi gear pulls. Just the factory oil cooler. On 93 PI is not needed. That same map (582whp) on the street rail pressure is in the 1600-1700 range so starting to reach its limit.

        Thanks! It was great working with you and glad I waited for these. Definitely was not looking for any records and as you know far from a max effort setup. I can't wait to see others results from these. Hopefully in the near future I will have some vids of friendly pulls with a 6266 speedtech car. Should be interesting to compare.

        Congrats on the results. Can't wait to see more of these installed!

        582 whp on 93 octane is really nice, spool seems to be good too!

        I would be real happy at 500+ RWHP on 93 at 19 psi. Engine should be able to live there for quite a while.

        Thank you for posting.
