260rs Lacking Power?

[DRKSKY32]

Hi guys just got the 260 dyno'd the other day and its running 154awkw, its fairly stock apart from apexi filters and some cat back stuff ( removed 1 muffler and replaced the other stock 1 with a new 1 )

but this seems really low for the RB26 I did a bit of a search and guys r running more power out of the rb25 with hardly any mods

any help would be great cheers

Sounds about right for a stock RB26 to me... Assuming you were on a 4wd dyno?

Remember that the car is awd, so the drivetrain will sap a fair amount of power...

yea I guess ur right only 1 way to fix it $$$$ also it was running a bit lean too so I cant even touch the boost till thats sorted, big fuel pump and adjustable reg will probably be the next step

They're not that fast from stock but the potential is there. Yep get a big (new) fuel pump but to fix the afrs you don't need an aftermarket fuel pressure regulator but a Nistune chip so that you can tune it. Next a 3in exhaust and a good boost controller and then turn up the boost!

There is little difference in power readings on a 4WD dyno over 2WD.

Yeah sounds about right, was it a hot day? That allways kills the power.

Mine dyno-ed 159awk stock with pods & exhaust so yours sounds pretty much on the money.

Cheers GW

yea 32C probably didnt help either

Sounds about right to me too - I'm at around the 150awkw mark with some mods to the '25. Tuner was estimating that the engine power was 200-210kw.

As Bob said - get a turbo-back exhaust at 3-3.5" with big mufflers and it won't be obnoxious, Nistune the ECU, add a couple of psi boost and see what a 'stock' 26 can really do.
