whats your timing when running more than 10 pounds on t25

[Rekless KA]

i have a t25 off an sr, 255 walbro fuel pump, stock ka injectors, 91 cams... i am currently running stock boost of sr, i would like to run between 9-12 pounds. whats your timing set at?

Get some injectors first man and something to control the fuel.

rule of thumb is .5 degrees for each pound of boost. I dont know if the t25 can even put out that much boost over 5K. That is a little much to take out at the dizzy though. Need some other way to control timing. You probably could but will defintally lose some mpg.

Timing will be more or less the same as something with a larger turbo, since we are speaking of pressure, which is what will cause the ping, not the flow. You would want to be at about 16 BTDC on the Dizzy. But you really need to think about some other method of control, like emanage or BTM.
