BirdmanZ Posted June 26, 2008 Share Posted June 26, 2008 This was a baseline pull on the APEXi base map for my PowerFC. AFR's were leaner than I would like to see. Boost peaked and held at 10psi. Engine is a stock RB26 with a PowerFC D-Jetro and full exhaust. Brandon Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted June 26, 2008 Share Posted June 26, 2008 That sure seems good for 10psi, though having to wind it out that far for the power kinda stinks. Tweak that tune and I'm sure it will be very nice, even for a stock turboed(?) RB26. Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted June 26, 2008 Author Share Posted June 26, 2008 I was very surprised by the power it made. I believe the turbos are stock on this engine, I have no reason to believe otherwise. As far as the RPM goes, I actually rev it to 8K on the street I just decided to shut it off early on the dyno, the RB26 loves RPM!

Careless Posted June 26, 2008 Share Posted June 26, 2008 I'm surprised too, you may have N1 or R33 turbos (is it an R33 engine?!) Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted June 26, 2008 Author Share Posted June 26, 2008 It was an R32 engine. I didn't find any other goodies on the engine which led me to believe that it was all stock. Even the clutch appeared to be a stocker. I had the turbos off and they had all the markings a set of stock turbos has. Either way, made some pretty impressive power for just 10psi!

stony Posted June 26, 2008 Share Posted June 26, 2008 After my first motor was all tuned at stock boost it made 352rwhp on a dynojet dyno. open face turbos 680 cc injector 3 inch exhaust and stock intercooler using SDSEFI. it made 392 at 15 PSI with the same setup. this was on 93 oct pump gas. The rb26 is an awesome engine with lots of potential... keep on it :> Quote Link to comment Share on other sites More sharing options...
J Taylor Posted June 27, 2008 Share Posted June 27, 2008 It says flywheel hp on the graph. Is that correct or is it actually wheel hp? 385 rwhp definately seems like alot of power with stock turbos at 10psi. 385 fwhp would seem alot closer to where I would think it would be. Never seen a dyno spit out fwhp #s though. JT Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted June 27, 2008 Author Share Posted June 27, 2008 It's horsepower at the wheels. I have no idea why it says flywheel power graph on top. The Dynapack software is funky like that, it will actually allow you to drastically alter the power number with that TCF number if you want to. We've had hundreds of cars on this dyno and it definitely measures power at the wheels. Brandon Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted June 27, 2008 Author Share Posted June 27, 2008 BTW, I have this setup for sale here: http://forums.hybridz.org/showthread.php?t=131635 Quote Link to comment Share on other sites More sharing options...
J Taylor Posted June 27, 2008 Share Posted June 27, 2008 Those are definately good numbers then. Hate to see you have to sell it. JT Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted June 27, 2008 Author Share Posted June 27, 2008 I'd really like to see what it would do with a proper tune at 15psi. But, yes I am trying to sell. These times are rough and the toys are always the first to go. Brandon Quote Link to comment Share on other sites More sharing options...
