S54 Dyno Database

Recently got my street build on the RK-Tunes dyno for a custom Alpha-N tune. Mods:
- Karbonious CSL airbox
- 280 272 Cat cams
- SuperSprint V1 Header, SS Catted section 1, SS oversized resonated section 2, SCZA muffler
- TMS pulleys

After Jordan doing his thing we ended up with 350 WHP & 261 Torque. Pretty happy with that.

plugs had maybe 10k to 15K miles. Is there a guide to perform a VANOS test? can it be performed with the schawben scan tool? Thanks!!

Plugs should be fine w/those low miles. I believe that a Schwaben will perform at least some of the tests, but not all? I've always used a GT1 type tool, but there are other means of running a VANOS test. Maybe search in the Coding/Tuning section for other recommendations.

How many miles on your plugs? Might want to perform a VANOS test as well.

Kassel thought it was plugs being a bit old. I replaced them but will not be able to get back to them for another run.

Why is it nosing over at 7,000rpms? Have you performed a VANOS test recently?

So what should I do next for more NA HP? Is the next step cams?

Yep. Though, I think that the current setup is solid as is. The funds might be better spent on a few DEs or track days.

Nice numbers man!! What BW turbo are you running? Turbo manifold?

Thanks! It is a maxpsi e85 kit with Spa manifold and the BW 364.5 sx-e

I’ll update mine, ~770 whp and 700 ft lbs. The BW maxed at 25psi, I’m planning on ordering a xona rotor hopefully. The afr was lower by .5 or so on the wideband in the car but still looking a little lean.

Wow, those are some big numbers!! Your car certainly goes to 11

Thonas Congrats bro, really nice numbers. Excited to see your torque figures as I'll be going SS stepped and oversize dual throughout. Im at 325/250 whp/wtw on dynojet now (turner csl map, oe euro header, scza) , a little more oomph in the midrange never hurt anyone.
