maskmanLS6 Posted May 31, 2012 Report Share Posted May 31, 2012 Im gonna risk getting scalded and ask a question thats probably been asked 100000000 times on here. I have my timing set at +4 with a Dune port and 140 psi compression, I have heard several different opinions on the benefits of advanced timing and the risk. I would like to hear the facts as to where the power gain is at in the power band, Im hearing from some people that the gain is on the bottom end but i always felt more gain on top end. Any input would be cool. Quote Link to comment Share on other sites More sharing options...
rodneym Posted May 31, 2012 Report Share Posted May 31, 2012 Dont worry. I have a timing plate and havent used it yet. Ill like to see what some of the guys that know say Quote Link to comment Share on other sites More sharing options...
maskmanLS6 Posted May 31, 2012 Author Report Share Posted May 31, 2012 I know that slower burning fuels can require a timing advance,, im running 93 pump gas and just using the advanced timing for some extra ponies. I would just like to know where the benefits are with pump gas. I understand that race fuel is more suited for higher timing and will deliver more power but where at ? Top end or bottom end?

Coupelx Posted May 31, 2012 Report Share Posted May 31, 2012 Usually gains you the 30 MPH you need on the topend to break 100mph Quote Link to comment Share on other sites More sharing options...
maskmanLS6 Posted May 31, 2012 Author Report Share Posted May 31, 2012 Usually gains you the 30 MPH you need on the topend to break 100mph I noticed a gain in the top end, not sure about the 100mph though. Considering bumping up compression and running some 100ll and trying +6 on timing to see what gains are in that, should be a good jump in power i hope.

rodneym Posted May 31, 2012 Report Share Posted May 31, 2012 im not sure. i need to put my timing plate on. I just bought it beause everybody told me it was a good gain. I would like to know where the power gain is. Quote Link to comment Share on other sites More sharing options...

I would like to know where the power gain is. Advance timing normally gives you power in the Higher RPM or top end. I know you already do run high octane but the more you advance the hire octane is required. Quote Link to comment Share on other sites More sharing options...

james berry Posted May 31, 2012 Report Share Posted May 31, 2012 I will correct myself here and post the facts. This is on a Dyno dyno days show that there is a correlation between advancing the timing and an increase in low-end torque. In general, each 1-degree of additional advance seems to bring the torque curve back by around 100 rpm. By advancing the timing by 4 degrees it has the effect of delivering torque at 2,600 rpm that would normally be realised at 3,000 rpm. Of course, it has also been noted that top end torque is adversely impacted in about the same ratio The result can be pinging cause by premature detonation. That is why higher-octane fuel can be good insurance if the timing is advanced. In hot weather when the air is warmer the amount of oxygen atoms in a given volume of air will be less that in cold air. This leans out the air/fuel mix. Once again, higher-octane fuel in the summer is good insurance. Similarly, in lower altitudes the air is denser and the stoichiometry (ratio of fuel to air) moves to lean so a higher octane fuel may be beneficial to avoid pinging. So if you have advanced the timing and go for a mid summer drive down to the beach you might like to take on a tank of 98 RON. I want to credit Reher-Morrison Racing Engine School for the information I have noticed personally more power in the MID TOP end range Partially due to wheel Spin Quote Link to comment Share on other sites More sharing options...

Coupelx Posted May 31, 2012 Report Share Posted May 31, 2012 Pre Detonation strikes again http://en.wikipedia....Engine_knocking read the whole thing. http://en.wikipedia.org/wiki/Ignition_timing this too. 30 seconds on google to find this.

twistingixxers Posted June 1, 2012 Report Share Posted June 1, 2012 Just buy one... install it and set it at +3 or +4 and enjoy going faster...I did..lol Quote Link to comment Share on other sites More sharing options...
