I just recently had the tranny go out on my truck and its actually gotten me really paranoid about blowing the engine now. I'm runnin 510rwhp with 140,000 miles on her. My race tune runs up to 30* of timing with just barely a haze of smoke out the exhaust. Now my question gets a little complicated. Is this timing pushing it a bit much safely or for longetivity? Would there be a better direction to go? More fueling with less timing at the risk of higher EGT's? Or would that just create the same cylinder pressures and be back to square one? I know I'm walking on thin ice when I ask for 500+hp and 200,000 mile longetivity but just wonderin if there are any small tips to help out in the long run.

Thanks,
Dustin

you want the motor to last a long time, turn the power down. You want to run high power, plan on motor repairs.

I have a tune in a guy's truck that is over 200k. We are running more timing and a lot more fuel, but I am not sure of the hp. ;)

I guess to be a little more clear what should I focus on for a 'cleaner' tune? The large amount of timing is sorta bothering me cuz I know thats about max I should be running. But would running less timing and finding another way to get the power back be safer?

i think there are people that are running alot more timing than that. i am pretty sure that pat runs abou 40 to 42 degrees

DONT run 40+ degrees of timing!

If it were my truck, I would back the timing down a little bit from where you are at.

How much pw do you run in that tune?

If you have a single cp3 you will be fine. that lb7 is tough as knotty pine.

remember you can set your max timing value as innsurance that you dont over advance. I think 25 is plenty, i dont see a good reson to go more than that for a daily driver.

30* should be perfectly safe as long as that your maximun timing table is set to that as well. As for longevity, any peice of equipment you bag on is going to fail earlier than one that is not. And if you've run for as long as you have with no problems one is not magicaly goin to appear due to your timing all of a sudden. I wouldnt push her much past 30* though. Thats what my max is

I have this on my DSP2 switch so its used rarely for the weekend hotrodding. 90% of the rest of the time its just on my 100 horse tow tune Nick gave me. I have my max timing table set at 30 and in my logs it will just barley touch it at redline. My max pulse width is about 2500us. Single CP3 with just a lift pump.

For only 2500 pulse width I think you could use a little less timing, for pw's over 3000 is when I use around 30* but this is just me everybody's truck's are not the same. If this is a 500rwhp tune your pw's should be around 3000+ though unless the rail psi is cranked but still 2800+

K I may drop the timing down a tick and throw in a bit more fuel. Thanks for everyones input.
