do you guys see anything wrong with the way i have my timing set up? i was told on another site that im over advancing my curve and it will lead to ultimate failure...

so far it hauls ***, doesnt ping, and starts, runs, and shuts down when i want it to.

i changed the timing to 32* all in at 3000rpm and i didnt see any major changes.

Your set up looks good to me very similar to what i have mines set at. and it runs and starts perfect too.

I've got mine at 28* with no vacuum advance. This is going to change though when I get my motor back from the machine shop since the setup is changing.

Thanks it makes me feel better hearing this. I get a lot of flack from gen1 sbc and BBC guys about my carbed LS.

@ 39* I have no signs of detonation at all. Going to drop it down to 32* for a pull then jump it up to 36* and then to 40* on the dyno tomorrow night to see what happens.

F them, are they looking at your tail lights? That is what matters

DEFINATELY let us know what you find with the timing!

75 vette
2002 ls1 - stock heads with rocker arms
Trex Cam
Victor Jr manifold w/ msd ignition
Speedhound Headers-flowmasters with H-pipe
3.70 gears
TH-400 with 3000 stall

I been playing around with my timing curve and I think I am close to having it perfectly tuned. I originally was running 36* but was told it could be damaging the motor. I was not hearing any pinging but the car is very loud so I didn't want to take my chances. I dropped it down to 30* and the car felt much slower. I am at 32* now and it pulls very hard all the way thru my rpm band.

Current set up: 20* @ 1000 ramping up to 32* @ 2800 dropping down to 28* at 4400 ramping back up to 32* at 5400 and riding out to 7000.

I found that dropping the timing down at max torque made a big difference, let me know what you guys think of my setup. I wonder if I should try ramping up to 34* 5400-7000 rpm. I will probably end up getting on a dyno to find out for sure what curve makes the most power. I will keep you guys posted. If anyone else gets on a dyno let me know what your results were.

Ok so after 5 hrs on the dyno tonight i have made some really good improvements and tried a lot of differnt things. I tried several different timing curves and also we had a 2in. HVH cnc'd carb spacer with us so we put that on and tried some pulls with it as well with different timing settings.

With a stepping up curve to 39* was not the best power maker ended up 398rwhp and 338rwtq

2in. spacer 404rwhp 340rwtq but the peak numbers aren't really that impressive what is impressive is that once the spacer was added starting at 3400rpm's hp went up 30rwhp and 20rwtq from 3400-5900rpm's with peak numbers coming close at 6600rpm's. The throttle response was amazingly increased!

I tried 33* with the spacer and power and torque dropped a lot on low end and 8hp 6tq on peak

I tried 37* and got the best peak hp and tq at 406hp and 346tq but lost a lot on the bottom end as well.

We found that after testing several other timing settings stepping and bringing all in at 2000rpm's that 35* all in at 2000rpm's had the best curve most power and torque across the entire curve and only down a 1/2hp land 3/4lbfttq.

I ended the night happy with the curve at 35* being the best coming all in at 2000 with the hvh spacer that is well worth the money couldn't believe the difference that the spacer had made. Oh we only dropped the jet's on the secondaries on the last pull and it smoothed out the air fuel big time, The spacer made a major improvement on the air fuel consistency along the curve.

I left out a lot of info i'm sure it's late any questions i'm sure i have some data i could give to maybe answer some questions. We learned a lot tonight

So, you did not attempt to bring timing where it was at peak power on the top end back up like you could? Or did you just not care to do so?

And you are using a LS1 right?

No the over all low end power to the peak curve at 35* was a lot better smoother and ramped faster than at 33* where i lost 22hp and 13lbtq on average till 6000 then it peaked only a tad bit higher. We did make a pull just to see what it would do at 28* like an injected LS that was a wasted useless pass....

Also this was funny just for fun to see the difference the Alternator had on power we made 2 back to back pulls at 35* it made 405.86hp 343.91tq with the alternator on with it unhooked it made 403.12hp and 339.59tq. Not that that info is helpfull but we did it just to see the change made more power with the alternator on and spinning than with out it lol

Nice run and nice numbers...... with that th400 and the 9inch robbing power. But the track numbers should be very nice. What octane gas are you using? I dont want anyone on the forum running out to try 40* of timing on 87 octane LOL!

So your best curve was 35* at 2000 rpm and held it that high all the way to redline? I have the same set up basically so I want to get it right so I can give it a try. Also did you play with you MAP timing?

My timing curve starts @ idle @ 25* 800rpms, by 2000rpms is 27*, then by 5100rpms it goes to 31* and stays there until my 6800rpm. We played with it on the dyno goin to 34* and lost almost over 10rwhp and then we lowered it to 29* and once again lost rwhp. My car seemed to be happy at 31*. I have not really messed with the MAP AC. The earlier HP numbers is with a 750 edelbrock carb, only change was to a Holley DP 750. This is through a TH350 with a 4k stall

I'm not running a map on mine. With my set up the 35* was the best, but with different cams and heads, compression changes things some.

I just changed the timing program on mine from 18 [email protected] through to end, to 20 initial 0-600, 38*600-3500,droping to 35* at 5000, ramping back up to 37* at 6000 through to end.(If I knew how to post a screen shot I would)
My 9.5:1 compression LY6 w/ 227/235 comp cam, ABSOLUTELY LOVES the added low rpm timing. I programmed in a timing drop back to 35* at 5000 because a felt that at peak torque it didnt need as much timing, and I had it back up to 37 at top revs based on LS 10's dyno info that showed peak power being better with the higher timing.
My car drives WORLDS better with the added low rpm timing.

Ok, i had my timing at 12 initial, then ramped up to 32 by 2000, now i bumped initial to 20, was able to close the throttle blades to idle back down, added 89 octane and there is no more dieseling when i kill it and then i bumped timing up to 35 by 2000, then from 4000 it goes to 33 at 5000 then back up to 35 by 6000 on up. Hard to tell the but o meter if it is running much better, but it seems the Trex likes the timing at 35 or so.

BASE TIMING:
0-300 rpm - 10 degrees
300 - 1100 rpm - 19 degrees
1100 - infinity 27 degrees

MAP:
17 degrees from 0 to 9.0 ramping down to 0 degrees at 11.0 to infinity.

TOTAL TIMING:
Total timing at idle is typically 36 degrees and light cruise will reach as high as 46 degrees. WOT is 27 degrees.

In drag strip testing, my car slowed down at 26 degrees and at 29 degrees, so I choose 27 degrees although there was no difference in performance at 27 and 28 degrees.

Rev limiter at 7000 RPM
