Quote » The engine is built to handle probably whatever boost i want to give it but we didn't refine the air/fuel mixture. i've got an upgraded MAF, FMU, 370 cc injectors and a Walbro fuel pump, but he said it still wasn't safe for high boost. (All that was just to get my daily back on the road running until we finished it up.) And yes it's running rich if you were wondering....[/quote]Ignoring the FMU.... the setup should be good for like ~10psi safely (since we don't know what rate the FMU is). I'm wondering if you're running rich because of the FMU though.... if there is fuel control for the 370's, the FMU should not be necessary. Anyways, if you have an upgraded ECU, just pop the molding off the passenger side where the ECU is and take a look. If it's a JWT it should be marked.

I'm running a T04E at 7 psi daily, but it's nice to know you can crank it when you want. and having gone through 3 engines i would rather build it up the first time.
Not trying to argue, just voicing my opinion as well....If you run a good enough fuel system (lol... jokes on me with that) that at a "measely" 7psi there isn't such a great danger of blowing the engine up.
I ran 9psi for a while daily with no harm done, ran 7psi daily otherwise since I installed my turbo earlier this year. I've also run at 12psi, but with such a small turbo (TD05 12B) I was definitely over the limit of my turbo. I know 2 other KAt's personally who run 7psi daily with no probs on stock engines, one with a Garrett T04 S/O .84 A/R, the other with a huge *** KKK. No problems dealing with boost.
