Update on me, I took it to get the start/VVEL issue looked at and dammit if the fuel pressure wasn't 20psi. I don't know if it's a pump install related issue or what but I talked to Seb and change is coming. I got a Radium surge tank, and I'm gonna go with twin 450s and run a single Stealth 340 into that. Also I already have bigger 1.32ar turbine housing that I have to get coated. So I'm guessing I'll be passing up that 670rwhp pretty handily next time on the rollers. Also having the Wacetrac, diff bushings and subframe bushings done at the same time.

Nothing to offer in the boost conversation, but I can certainly attest to the C2 cams making some real noise. It's nothing like a Hemi/LS big cam chop, but the car definitely sounds different at idle, especially on my E85 map. Driving is no different if you're just putt-putting around town, but about 3,500 they start to sneak in there and then by 4k, they certainly make their presence known. Could be like hearing the intake growl before putting exhaust on, though. I don't have the whistles and whooshy noises to cover the cam sound up.

I don't know what to say. Mine just dont sound all lopey to me at all. The C1s in Matts car don't either. What I was talking about is the chatter they make in the valvetrain. It's definitely more than stock but the C1s are noisier to my VA disability ears anyway. I'll upload an idle clip to my YouTube.

Can't hear it. Too much Yappie Yappie going on. LOL I would not expect to hear much of a difference in the idle. It doesn't help
being in the garage.

Any way you put it , it's just not much of a difference.
