20+ Horsepower from exhaust

Does anyone know the valve diameters or port areas for these cars? If we can find those, we can calculate the theoretical and most likely HP limits of these cars (without doing any serious engine work first).

Insite,
Good stuff, man.

Fletch,
Custom mapping will yield the highest gains for sure. But even then it's still minimal gains. Dyno charts are great and all but you need to know the facts behind the numbers. Showing gains on 94 or 104 octane gas means nothing since we only have 91 in CA.

Why only 91 in CA? I live in $hit hole USA (MI) and I can get octane up to 110, which I run in my bike but not my Porsche

You just have to look for it. You can blend to get 93 or 94. Try this blend chart if you need it.http://members.aol.com/SteveL1994/public/OctaneChart.xls

Well, I can get 104 octane down the street at the local 76. But at almost $5/gallon I'll pass. I'm just suspicious of tuning for OBDII cars. Even Jim Conforti of BMW tuning fame said that OBDII is a ******************** and that getting 5-6hp is about it. Of course he's talking about a different car (E46 M3) but since all cars since '96 have OBDII I'd guess that we're in the same boat.

Remember in CA, the state govt has fiddled with EVERYTHING! Wouldnt be surprised if 92 and up was illegal!

Richard -

when i get home this evening i'll run a workup on the 3.2's mathematical likely / theoretical limits with these change.

[Richard Truss]

i look forward to hearing what you have to say.
