Besides the fact that I'm being cheap right now, I've been wanting to
see how far I could really go with my early 85 for the same reason.

That's what he told me, anyway.  I trust him ;-).

I just get that from doing the horsepower calculations for my weight.
If you're running a heavier car, you'll max them out at a lower speed.
I was also being a little conservative.  For my weight of 3270, 96mph
is 230hp, and 99mph is 253hp.  Somewhere in that range is where the
30# injectors will max out, but you've gotta have an air/fuel meter
to know exactly when you're done...any smart person would just go to
bigger injectors before this point, but I'm curious ;-).  Yes, I've
holed a piston before, but it was the TFIs fault, not my fuel system.

At any rate, the 30s will give me enough power to run a 13.99 if I
can get a really good takeoff.  I figure that would be cool to do...
speaking of cool, I'll probably need a serious intercooler, though,
to accomplish that.

I agree.  Retarding does help a little, but it would be much more
cost effective to just put a different cam in than buying an
adjustable cam pulley.
