which power kit do I get

[Jake Raby]

Yet again we are talking generally here.. Some systems DO give some sort of gain, but the question is how much each one of those additional HP costs.

I sourced a set of expensive headers for my Wife's 996 Land Speed Car (that holds 4 records) and installed them.. I did back to back dyno work and no matter what I could not get back the 6Hp that they cost me, until I removed them and went back to stock. Using the data logger (DL-2) the 0-60 and 40-80 ETs substantiated what the dyno illustrated.

How much is 5Hp worth??? I can get 5-7 (RWHP) with a 225.00 pulley!
