With your camshaft and heads and everything in your signature.....your guess is as good as mine.
what should i run my timing at on my 351W? im not sure whats its on now we jsut set it by ear because there was no marks on my balancer, but i just picked up some msd timing tape...thanks!!! also what should run my total advanced timing at for the drag strip!
I adjusted my timing on the dyno with 89 octane in the car. My car didn't ping even with 20 degrees, and made the most power at 18. I didn't just play with timing and guess, I did it on the dyno, and also run 89 octane because thats what I had in it that day, I could probably run 87 and be fine!
I FINALLY checked my timing last night.......2 degrees. I couldn't believe I've been running 8-10 degrees retarded for this long. In any event, I reset it back to 10 degrees and the thing feels like a whole new monster. Throttle response is back AND my car doesn't backfire in the low rpms anymore.
I can't wait to get off work so I can get back on the highway and let 'er rip. Now my car doesn't fall on its face in the high rpms. Matter of fact, feels like she'll make power all the way up to 5500. ****, she feels like she'll make power past that.
Oh well....I'm going to bump it up to 12-14 and see how she runs, hopefully she'll run even better.
I noticed when I was under the car that I have a Pro Street harmonic balancer. Is this a badass harmonic balancer or not?The ****ing thing had 3 sets of numbers. It took a minute to figure out which hash marks to use. What the hell are they all for?
I believe Dave set the timing on my Capri to 14. I'm all like...... now...
So than it IS a good idea to bump the timing up to say 12-14?
You want to run as much timing as you can without detonation....so toss in some 93 octane, bump the timing by a degree and take it for a ride. If you don't hear any pinging, bump it another degree and go again.
Keep going until it pings and then back it down two degrees. Every car is different. Some cars can go to 16 degrees without pinging, while mine pings at 14 degrees.
Also keep in mind weather conditions can play a role, so you may find it still pings on really warm days requiring you to knock it down a degree again.
Basically whay i'm saying is you'll have to stay on top of it.
Ummm......I believe it defeats the purpose to advance your timing to the point of having to run a higher octane. The theory behind it is to advance your timing enough, but not TOO much that you have to run a higher octane. If you have to run a higher octane (which is usually due to spark knock) than you're defeating the purpose. You shouldn't have to run a higher octane on a LOW compression car. Apparently, our engines weren't built to run a high octane. Matter of fact, higher octanes in a low compression car can sometimes lead to unburnt fuel on the cylinder walls and you simply don't want that.
As far as I know......11 to 12 degrees on 87 octane should be perfect....but I could be wrong.
Well that definitely makes sense, but I would think that increasing even further and running high octane would only improve in somewhat of a perpetual fashion. I know with increased timing and Underdrives I ran a 14.2 at 400 ft elevation. First time to ever drive a car down the quarter. Certainly helped me! Also, now that I have my S/C and chip I have to run higher octane, no choice. I know this is commonplace, but same engine and same internal components...
But I thought you didn't want to have to go to a higher octane when bumping the timing.....I thought you wanted to keep the octane low and the timing as high as possible without detonation?

It also has a lot to do with where you live and the quality of gas your area is getting.
