Default If you boost spike, how can you tell if you messed up your motor?

I knew it.....my homemade MBC.....dammit.

The years of ghetto engineering finally got me. I spiked pretty bad....near 30psi.

How can I tell if I screwed anything up? The car drives fine. I have forged internals, no aftermarket sleeves, and a blockguard.

You'd know if something was broken.

Homemade mbcs = bad idea

Alrighty. Thanks a lot for the quick replies. I was getting paranoid. My car hesistates, but I think it always did that.

I will now invest in a real boost controller. Know of any around $200? I'm broke.

Hehe, it's all good guys. I didn't feel any crazy power increase. As soon as I saw that gauge fly up, I got off the gas real quick.

It is definitely time to invest in some good turbo parts now.

My low-buck mbc didn't work that well either. It would spike when the spring was cold, and old less and less boost as it warmed up.
