Streetport & Timing ?
Just thinking about timing a little and Im not really sure if timing should be advanced slighlty or retarded slightly when running a streetport, I know a streetport is just another mod like a DP so if you were to retard timing for a streetport (like im thinking should) then you would also retard timing for other mods such as that, Right ?
Sorry bout the stupid question but a yes or no is all im looking for...
Thanks

From what Dave Barninger told me with my Power FC map and street ported motor (plus other mods), he had split the timing and retarded the ignition. Not sure what that means. The experts will need to chime in

I dunno: CAUTION DUMPING
Dump warning: I may not answer for any questions but my fingers are typing, dumping out part my brain so I can re-allocate the space in the noggin'.
Every porting job is different in terms of the increases in flow. The adjustments are thus different.
I view the air flow as "the whole" stream, from entry to exit. You can turn this into an equation using some basic laws and equations.
How and when you ignite is part of that equation. Where you advance and why are good questions. I don't have definitive answers, just opinions formed from my and others experiences.
I refrain from talking about what I don't know, or don't believe sharing would have any benefit to the intended target audience: read non-experienced tuner.
Knowing where you car makes power is esstential. Road tuning is the best, but throwing the car on a dyno and baselining it is very valuable, too.
Most agree that advancing timing after you torque yields increases in HP.
Tweaking the split within the limits of your ingition system has positive effects too.
Taking the split into negatives (trailing firing before leading...maybe this what some people call "split tuning") is a bad thing.
Ignition amplification has immediate positive results.
Adding more ground connections between key areas of the car clears up problems too.
There are no shortcuts to a slow and methodical approach to tuning your car: the short cut is doing the right way, in small steps.
