Hi everyone
I've decided to have some fun modifying my 997S. These cars are crying out for more power as the chassis is so capable! As many of you will be aware, there are a multitude of tuning firms out there offering a plethora of bits and pieces together with claims that vary from 'ummmm...' to 'you've got to be kidding'! So I've decided to assist a UK-based tuner (mostly by allowing them to use my car for development but also with some ideas) to evaluate and test various options and to come up with a real 400BHP package. I'll tell you who the tuner is once we've finalised all the arrangements. My goal in this is to end up with a 400+ BHP 997S and to be able to report back on the modifications and their effectiveness. The tuner's is to be able to offer this package, fully proven on the dyno and with independent magazine performance tests to back it up, to anyone else who's interested.
So what approach will be used to go for the 'Magic 400'? Firstly, there is no intention to look at forced induction - this is a 'naturally aspirated' project. So in the absence of a supercharger, there is no hope of reaching this figure simply with bolt-on bits. There just isn't that amount of gain left in the standard motor and any claims to the contrary really are B/S. The belief is, currently, that the following will likely be required - airbox / filters, bigger throttle body, cams, exhaust manifolds, 200-cell cats and an ECU designed specifically to work with the complete package. Sports silencers would be an option but the standard 997 silencers are not restrictive and should be able to be retained. The standard car will be tested and dyno'd, then the various modifications will be applied to evaluate their effectiveness both separately and in combination. The tuner is hoping to offer the modifications in stages, each of which will add a quantifiable increase in performance over the previous stage. Stage 3 will be the complete package giving you over 400 BHP.
The whole 'Stages' project will be approached without preconceptions as to what should work. For example it isn't currently known whether the best 'bang for buck' for Stage 1 will be intake, exhaust or whatever. Evaluations will be done to ascertain what works and the tuning stages designed to give an effective performance lift with each next stage.
I'm not entirely sure of timescales yet, but there are already a number of parts on order from Porsche Motorsports for evaluation.
I would add that I have no business interest with regard to the tuner concerned - I'm just looking forward to a faster car! They will simply be using my car for development (and I'm incredibly nosey so they'll have to put up with my presence too)!!!. I will report back as things progress.
