My set-up is nearly exact to another Member who's 700-plus RWHP, and my low-side is starting to drop, even though my high-side is yet to drop much if any. I haven't been able to get to the track yet, and my runs don't get much past about 4th gear, so perhaps I'll see the high-side start falling a little more by the end of the track. Runs that short don't tax the fuel system too much at this power, but what remains to be seen is what happens making a full pass. I'll be logging when I do make it out there, so I'll be watching, and can make a better decision based off data I collect.

I've seen Members here and on HPT say conflicting things. Some say as long as the high-side doesn't fall much, the low-side doesn't matter too much, to a point. It seems the consensus, though, is after about 700, you have to get into the fuel system. There's some tuning you can do that might help a bit (with the stock fuel system) at that level, but you're really at the end. I'd plan on a low-side when doing the cam, just so you're not back in the shop right after getting the H/C treatment.

Some of this will depend on your usage, too. Since you're not going to road course it, you might be able to get away with a booster for a little bit (at your Phase I), but while many have had good luck, I'm not sure how much faith I'd leave in it much past 700. That's a lotta' money on the line to trust a booster. If you're on the street or strip, your runs will be relatively short, so maybe a booster will be "okay", but I'd be careful. That's just me though...

I'll say on OEM tires that this power is not unmanageable, but I'm not making much use of what I have. I can't go WOT until I'm just before the 2-3-shift. It's still spinning after that, but I usually have enough momentum. It's been too cool (until this week) to really run the DRs, but I'll soon see how traction is with them on.

JMHO.
