How Much Timing To Pull For Boost

You don’t use a single line table to “pull timing per psi of boost”. You have a Base Timing Table that has both an RPM axis and a Boost/Vacuum axis. Just set the timing the way you want it in that table. You can program both the X/Y axis with the values you want as well.

The additional 5 degrees of ignition timing (from 18-23 degrees) resulted in a jump of over 50 hp at 6,000 rpm with the boost and relative power gains increasing with engine speed. You will notice that each successive step up in ignition timing increased the power output of the turbocharged 4.8L.

You will notice that each successive step up in ignition timing increased the power output of the turbocharged 4.8L. Starting at 18 degrees, the turbo 4.8L produced 539 hp and 502 lb-ft of torque, but stepping up to 20 degrees increase the numbers to 551 hp and 507 lb-ft of torque.

Ignition Timing for boost. How much to pull per psi?

Jun 6, 2022As extra trick you can try to stabilize idle with timing: Move the lowest column just below the idle rpm, like 900rpm. Set the next column at your target idle rpm. Add few degrees on the lowest column. This way the timing advances if the rpm drops below your idle target and that tends to drive rpm back up. Ignition Timing for boost.

How much timing to pull per pound of boost? | Ford Mustang Forums

14 initial and set dial to 3/4 to 1. with 14 psi you would theretically get you 16 deg total timing at max psi. and 3/4 you would theoretically see 20 deg total at max psi. 1982 Ford Fairmont Futura H/C/I, fuel injected and turbocharged 10.67@128 W wick Registered Joined Nov 12, 2006 986 Posts #3 · Dec 30, 2007 I set mine on 2 and work from there.

Boost and timing – Ford Mustang Forums

time for math: if you are running 8psi of boost and there is no reason to pull timing for the first two psi, you have only 6 pounds you will be pulling timing from. 6psi X 2* per psi = 12* you need to pull. 30.25* stock timing – 12* = 18.25* total timing. 18.25 is ultra conservative on your combo and therefore the minimum timing i would run.

How much timing with boost? | LS1GTO Forums

Well that’s exactly what I’m running is 18 degrees with 11’pounds of boost. However I was running 23 degrees using meth but with less boost. Now we only use the meth.for cooling instead of timing but I’m running 105 octane fuel in the car right now and thought that 18 degrees was real conservative with that octane.

what timing retard with boost? for safe tune – Don Terrill’s Speed-Talk

For pump gas and a low compression ratio engine (8.5:1 or less and 8 psi boost you want the timing to retard to about 27deg (26 to 30deg) when its under the full boost (8 psi) . The amount of timing retard rate is programed relative the the boost increase rate. degrees of timing retard per pound of boost.

How much timing I should I pull running 18psi? – HybridZ

Ok I have read different theory’s but none reguarding non-crossflow 2 valve per cylinder engines. Right now my total timing is 39 degrees from 3500-6500. By 19psi it drops to 16 degrees so roughly 1.1 degrees per psi. This seems to fit most people theorys on how much to be pulled, but when I think of it as 16 degrees at 19psi that seems alot.

Timing vs Boost for making power with road tuning

USA. When I tune I look at what the car can hold in terms of TQ. My car can do 350 TQ before things start to get weak or break. So what I do is start by having a base line timing map like Andre talks about in his video. Then start the boost at 15 – 20psi and watch the TQ climb. The formula for HP = TQ*RPM / 5252.

increase boost ? Pulling timing? – Dodge SRT Forum

Timing was pulled boosting that high. Especially on S0, however it has been said that S0 give you the most aggressive timing curve beside the other Staged PCMs. That’s why you see most going back to the S0 PCM. You gained little at all by kicking boost up to 20 psi, just because I can bet you the PCM pulled alot of timing.

More Boost or More Timing Advance? – DSMtuners.com

A larger spread in boost will make more power then timing alone (like 15 psi with 19 degree’s of timing will make more power then 16 psi with say 14 degree’s). But your talking about a 5+ psi difference then boost wins, if the tune is correct. Jayson GVR4 630/2000 1992 Plymouth Laser RS Turbo Manual 1988 RWD · Automatic Street Build Aug 12, 2008 #6

What is ” Boost Timing” ? – HOBBYWING North America

As an example, boost timing is 20, start RPM is 6,000, and timing punch is 300. Using that, all the boost will have been applied by 12,000rpm (6,000+ [300 x 20]=12,000). So from that, you can see that using a bigger timing punch value will result in the full boost being applied later, which makes the application smoother, and generates less heat.

What should the total timing be on a car at boost. – NICOclub

So for 15psi, you’d pull 10 degrees based off of “Structure’s” reccomendations (.75 degree per psi)… 15psi – 2 = 13 13 x .75 = 9.75, or -10 degrees. So you’d want ~18 degrees of total timing for 15psi on pump gas, on a KA motor. That’s about right, from everything I’ve read. – Brian Thats about sounds right to me.

Nitrous Tuning. Timing retard determined by shot size or…

I would still pull timing from the boost only map on a 50-75 shot unless your are running a stand alone with race gas. … You get an idea of how much timing you can run on boost then do the basic 2deg per 50hp of nitrous. But with proper plug reading you’d be surprised what these motors can take with good fuel and a good tune.

Boost vs Timing on pump gas? | SVTPerformance.com

I dont think to many people have gone over 15-16 degrees of timing on pump gas with 20 plus psi though. Keep in mind when running lower timing your EGTs are going to be higher. Also, since you are running more boost your IATs are going to be higher as well then those of a car with less boost. Apr 3, 2014.

Every tuner is different. 20psi and 16 degrees of timing will make similar power to 18psi and 18-19 degrees of timing.. Here is how I see it too. The computer is going to pull timing at a certain point or Temp.. Boost doesn’t retard.. It will always boost 20psi.. Feb 1, 2013 #5 JRS03 Whipple FTW!!!!

boost and timing question? – River Daves Place

on my blown 572, im running around 12 pounds of boost with 100 octane low lead through an intercooler. my compression is set at 8to1 and my distributor is locked out. i usually run the timing locked out at around 24 degrees but i want it to run better while its not on boost. i was thinking of running a boost timing master from msd that will pull 1,2 or 3 degrees of timing out for every pound …

timing vs boost for traction – Dodge SRT Forum

Ok the best way i can explain it would be to keep lower timing in first and build a nice steady ramp on up in the power band until i reach my goal overal timing… which at the moment is 22 total degrees at 23 psi… For instance 15 degrees ramped to 20 in first 20 ramped to 23 in second and 23 on in third..
