Many others, including myself, have pushed stock cams and heads on a 3.0 and I think the wall was around 600AWHp 650 TOPS depending on dnyo.

But that is due to the air flow stock cams and heads can flow. There is a limit. But I sneak in MORE air via a HIGHLY oxygenated fuel. You can see however that past 6250 power starts to take a dive due to this. Turbos are still pumping out the same if not even higher boost, (probably higher psi due to restriction increasing at higher RPM) but power is dropping. All due to the heads and cams running out.

I am almost done with pushing this 3.0L stock head/cam setup. Have some track visits to do to complete it.

And basically stock heads, CXracing intercooler. About as simple td05 setup as can be done. Amazing results.

E95 is magic juice!

Good cams and heads will be interesting.

I do have hi rev springs in the heads as I did a lot of testing with cams, then sold them and went back to stock cams to get some bottom end back. And to see how far I could push stock heads and cams.

Still never answered my q about the spark plugs

I always have it set to smoothing=2 as default, SO here it is with smoothing=1

Can't see the Champions hurting a low power car, but really don't think they would help either. They are really for high HP race applications.

Thanks. Eliminates the needs of indexing tho im sure no one does that these days.

Even with a twinpower on a brand new OEM ignition (PTU, coils, and wires) I had breakup with E85 at 32+ psi. With Denso Iridiums (which I'm a huge fan of) it was horrible. Went to the non projected plugs with a tight gap and it improved but my logs still showed significant back steps in RPM at peak torque (IE peak cylinder pressure). Went to flat electrode plugs like these:

...and it further improved but the $10 a piece plugs I was running were discontinued and the only plugs available now of that construction are ~$34 a piece which is F'in ridiculous. Ended up doing some research on plug attributes/characteristics and settled on the Champions. I'm no fan of the brand but they work great. They are one of if not THE only option out there with an off the wall contruct. Maybe if we continue to keep a demand on the part number it won't go away.

Big take aways of the surface discharge plugs are that they're very resistant to blow out and fouling. They're not rotary engine specific either. F1 used to use em back in the day.
