Paging Audi2ptzero...(repost from the main forum)

Octane · 02-01-2005, 12:22 PM

And anyone else who may have knowledge on this. Cars in the shop getting its 60K maintenance done. So I decided to throw on couple other things while they were in the neighborhood. I had the mod bug and decided to get an N75J valve since I needed to buy something for the car. I figured that since I have the upgraded injectors (310s) w/ the 310 software that I really wouldn't run into issues like overboosting? Just looking for your thoughts on this. And since I don't have a VAG if I did hit limp mode I can just disconnect the negative terminal on the battery and put the old N75 on and that will clear limp mode right?

since boosting in winter would be 14-15psi and summer could have the potential to be 24psi. I am currently at 21psi in the summer. I know the winter air is denser than summer...do you foresee it being an issue...or really the same difference?

Problem might be in that the adv timing will be too high for 24psi unless you feel like running higher octane. Also have to watch out for the IAT's since they will also increase with more boost.

That will get higher as you increase the boost level.

than 93 octane.

which means you can check block 026 during wot and see how high the voltage gets. Max is around 26 so if your near that right now with the setup you have then you will need higher octane if you push the boost even higher.

Max is around 26 so if your near that right now with the setup you have then you will need higher octane if you push the boost even higher.
