[s-cars] urS4 chipped boost level?

[Taka Mizutani]

You mention only 340hp with RS2 stuff- what is your take on the claims by
several
tuners of 370hp on pump gas w/ full RS2- EM, turbo, MAF, injectors,
software?

I've driven full RS2 cars and I don't think that 320-340hp is a proper
assessment- my
chipped 200q was very conservatively a 260-265hp car, possibly 270-280 and
full RS2
cars are waaaaaay faster- I would estimate far more than 50hp, closer to the
90-100hp
gain judging by the difference in acceleration. They will run away from my
old 200.

Normally aspirated Mustang Cobras ('99 & '01) can rate a decent 320hp with
about 3300-3400 lbs.
curb weight, will pull about the same as a full RS2 car, maybe a little
stronger, with a good 500lb.
weight advantage.
