Priced out, cat delete - similar cost; full exhaust -similar cost; pulleys- similar cost; supercharger - a few hundred bucks cheaper for the 16V than the 32V, but not as much CLAIMED HP output. etc etc.... When it comes to supercharging, I question whether the 16V can keep up with the gains of a 32V motor.
Need hard numbers to back those claims up. Lots of theories out there, and info supposedly all over the internet, but not easy to find. Where are these elusive dyno numbers for these cars (again, bone stock)? Modified, all bets are off for BOTH engines....
Also would love to see info backing up claims that similar mods on 16V motor exceed 32V motor. Dyno charts there as well. No claims, or theories. Just facts.
Claiming that a 16V motor is the best motor Porsche ever made is an opinion, and certainly should not be discounted, because we all have them, but facts are facts.
The following link has some theories contrary to your explanation, but again, there is no hard evidence offered there either...
16V vs 32V Engines suitability for tuning? - Rennlist Discussion Forums |
I don't trust dyno numbers, but feel free to search for them. I could just tell you stuff, but I think that spoils the adventure of owning a 928. What speaks best is what I am doing for myself, and that is a couple of 16v motors, both will be based on a 85/86 US short blocks with Euro S top ends. One close to stock, one with a hotter than Euro S cam and a bored and possibly stroked block.
Initially I am using modified US 85/86 brains with custom chips, but next step is a sharktune or more, and next after that "maybe" is to adapt an S4 brain or at least maybe the ignition brain with knock detection and retard circuits. I tend to stick to Euro S 84/86 because the intakes etc. are already setup for LH injection and conversion to US brains.
