How would a failed WG blow the motor? Wouldnt you have to not notice the high boost?

Is your wastegate pipe dumping or routed back to exhaust?

Not like you can't hear it opening or something. I guess it's a matter of how quick you react to a nonfunctioning EWG. There's not much to 'em. The spring either works or it doesn't. Worst case it leaks and bleeds off too much boost.

It's a dump, so in my case, it would be hard to miss. However initially I had not planned it that way. I have seen wastegates stick (bad design and actually a BEGi wastegate for that matter) and the results as motors spooled past 20 PSI. Now do I think it would happen to me... nah, but originally I was planning to route the wastegate back into the exhaust. I guess I could have saved $150 with a cheap wastegate.

I'd imagine the TEC III has some sort of overboost cut.

Cool project, very interested to see how it holds up. Are you planning on taking it to some track days or anything like that?

The wastegate was spec'd before the engine management. I had some original ideas that were very different than the final implementation.

Dammit Mark,

Man, you really screwed up with that wastegate. Why can't you get it right the first time instead of changing your plans in the middle of your project?!

Ok, here are some real numbers datalogged from a 3rd gear roll on at about 70 MPH.

5 PSI at 4500
15 PSI at 5000
20 PSI at 5300

Street tune on pump gas. Yes, you can roll into the throttle and break the Falken Azenis loose in 3rd gear (six speed tranny with 3.636 diff.)

Seems that we hit the injector limit due to the factory rail at 20 PSI and 8500 RPM with a duty cycle of 90%. This is with the 880 cc/min injectors and walbro 255 HP pump. 11.2:1 AF Ratio, texas 93 octane.
