Power Curves

[VinceM]

Thought I'd share the results of my power run at SRR at the weekend. Graphs should be fairly self explanatory. Bottom graph is the flywheel figure - question I have is that this is meant to be around 100 over at the wheel figures, so which one of these is more accurate - I guess the "at the wheels" figure would be as that's what's being measured directly.

Recap of set up/mods: 2004 LS1 Monaro VXR wortec cat back with 100cell cats and 1 7/8 LT headers, VCM intake (not OTR), MAFLess remap, MF heads (LS2/6 5 way CNC ported), 222/226 (0.605" lift) cam.

Curves are very smooth as you can see, some final tweaking to the mapping needed which should be done this weekend.

So my question is, does this look about right (I guess it does, I'm asking for an opinion) and what more can I get in the future? No funds for FI, so am thinking FAST or similar with 102mm TB. I like the way the car drives now, save for some slight roughness at cold first thing in the morning.

Thanks - I did have a base line figures of a standard VXR LS1 with Wortec cat back and K&N panel filter with 2 hole mod and that was 316bhp. That is at the wheels.

Yes the afr is a bit wild but hopefully that will be resolved soon.

Thanks for the comments etc. Whilst I think the intake is the next logical step what is the thinking behind this? Is it from experience or is there something in those graphs I'm not seeing. My learning curve is a fair bit steeper than that power curve lol

Definitely needs a decent intake, or more accurately a bigger TB. Stock LS1 TB will be holding you back.

TB on it's own or the intake and TB combo?
