Hi all, I just built a Predator 212 and am now trying to fine tune it. Idles great, very snappy off idle and mid range, but at WOT it gets to around 4,200 RPM pretty quickly but then hits a wall. When it's on the stand it will hit 6-7K.
My main question is around expectations...should I be able to reach 6K+ RPM under load?
Here's the specs:
- Predator 212 Hemi w/ governor & oil sensor removed (stock piston & rings)
- Billet connecting rod & flywheel
- Mod 2 cam
- 22lb springs
- Mikuni 22mm carb (Japan version)
- 140 main jet
- Needle is 1 notch off the lowest option
- Connected to a TAV2 / Comet torque convertor
I did a WOT run then shut it down to see what the plug looked like and she's still clean as a whistle. Probably too clean (although the whole setup has barely 30 mins on it).
I suspect I need to jet it up quite a bit but wanted to get some input from the more experienced folks before opening the wallet up further.
