I'm planing to turn the boost to 20-22psi. what you guys think? is it going to be safe to do that ?

 

this is where im a n00b but is it good to turn up the boost if your car is pulling timing? or is that such a small amout that its ok?

 

why is the timing in between your cylinders so inconsistent on the first run?... 4.5 degrees is not a lot but a decent number

you really aught to check out your egt before turning the boost up, for performance, one should use volume, not pressure to make power.

 

ya thats what i was wondering why on the first run its not pulling timing on cylinders 1 ad 4 but it its on 2 and 3?

 

second pull kind a going up hill, if it makes any different

what do you mean by EGT ?

 

exhaust gas temperature, you want to keep it down, you have a big turbo that pushes a lot of volume... too much pressure will raise the temperature of the turbo and heat up your intake charge, nevermind that you have to retard the timing so far, and the exhaust being so hot will melt things you never thought possible... which would obviosly cause problems... its quite a large part of tuning, helps keep the intake temp down, which makes more efficient power, and the heat will mess up your air/fuel ratio.

 

is there any number that is the lmit for the high or low temp ? I'll log that too see what is the temp of intake and exhaust.

 

i think like 1200 is a slightly high, but ok running number, 1400 wont do too much, 1600 will melt your windshield haha, just kidding, but that is as high as the autometer gauges go, so you can just imagine...

 

you will have to check around to see what is ok for these cars... and i dont think that the car can read the egt, so you will have to get a pyrometer kit to check it, but if i were you id check around to see how close you can have the timing with a safe amount of boost instead of blowing all the work and $$ you dumped into your car for a few months of fun. if you want an autometer pyrometer, i have a distributor account with them, prices are a bit better than normal. its like 129 + shipping for it.
