Hi Guys
OK with my limited "software" tuning experience I have played around quite a bit with my turboed A4 now and once I acquire my S4 I would like too obviously squeeze as much potential from that awesome v8 as possible. Now when tuning a turboed car its mainly about achieving extra boost and that with optimal timing/fueling gives great increases in power, so with a NA motor whats the best way too tune them?

Not much really. For one, aim at going richer and getting "best power" AFR which is around 12:1. Secondly, advance timing to a bleeding edge of what motor can take. That's it. And no, V8 is not that awesome (only saying since I have V6 with turbos  ) |

Build a RS4 motor. DTM-style intake, larger intake manifolds, port/polish of cylinder head, lightening and balancing of the bottom end, dry-sump oiling, pulley reducers, lightweight flywheel / balancer, camshafts, valve-springs, fast-velocity headers, titanium exhaust, built fuel system.
Build a RS6 motor. Heavy-duty clutch, lower compression ratio and connecting rods (?) re-build, rs6 turbo headers which probably dont fit thus requiring custom exhaust plumbing for the turbo, single versus dual-turbo decision, inter-cooler plumbing, water-meth plumbing, ecu reprogramming, etc.
Buy the APR Supercharger kit for $15,000.
Buy a Stage 3 B5 S4 Avant for $15,000.

Sorry. The NA v8 isn't very responsive to tuning. Even with an SC it really isn't built for higher cylinder pressures.
Get an audi with a proper motor.

Moral hazard man, moral hazard.
I was looking for proper Cayenne 18Z rotors and wound up on the B6/B7 AZ forum. Racingbrake apparently is making some bolt-on rotor and upon realizing they were planning on building it for the B6/B7 chassis, I wrote on the post: "You should really make this rotor for a non-POS chassis. This thread sucks." LOL... sorry OP. TBH, I'd LOVE to build up a new 3.2 V6 into a single-turbo monster to be put into a B7 RS4 body... <drool> |

A pretty ignorant statement.... Honda's weren't built for higher cylinder pressures either, but they work VERY well. And an Audi with a proper "motor" would be an I5 vehicle. Hope you weren't hinting at the inefficient 2.7tt. |

I5 >> 2.7tt > v10 > 4.2tt > 3.0sc >> 2.0t > 1.8t > ..............................
way way down at the bottom somewhere is the NA v8 used in the S4, RS4 and S5
honda motors work just fine with high boost; you just have to build the motor.
2.7t and I5 don't need any internal work. stock block + internals are just fine.
I think we can all agree the I5 is definitely a proper motor.

Your list is right on spot with what I'd say! I just don't understand why the V8 doesn't seem to repond well to boost. Usually, engines that make decent power in N/A form have significant gains from boost. Maybe it's poor tuning in their case? Not sure. As far as The Honda's go, internals are certainly advised however my friend had a bone stock 170k miles GSR with a GT3076 slapped on it and made 501whp. Then went to the track and ran back to back 11.1's @ 129mph. Who knows how long it would last like that though. I <3 my I5! |
