Unicorn II update....

Well, she's running.

Basic break-in tune, pretty conservative was 411hp/428tq at 9psi/pump gas.

Went back after break-in and made another baseline. It was 438/461 at 9psi/pump gas.

We started turning the boost up a little. At 12 psi, it went to 492/615-pump gas. But, we started getting pig rich up top and Blake was tuning less fuel in. We got an 18 psi spike and she blew a head gasket on #8.

I'm glad it blew actually. Come to find out, the exhaust valve guide on #5 was dumping oil in the cylinder. So, very possibly, I had a weak chamber on #5 as a result. So, at the moment, the heads are getting clened up and new valve guides installed.

Hopefully an increase in hp numbers will follow at the same boost levels once I'm not interupting the combustion process by dumping oil in #5.

I'll try and update again when she's back up. We plan to go much higher with the boost level

But, there's just so much that little 60-1 can do. It's falling off pretty good at the end.

Whenever I get my sick computer back, I'll post up dyno graphs.

Cool Brad! I was wondering where you have been. I'm sure it will be a monster after you get the bugs worked out.

Way to go. It's more than enough for a street car.

I'll make sure to do that......I actually didn't take any new pics once it got running. I was too busy enjoying it I guess.

I actually drove it to a show in Chattanooga and it won "Best Engine". I don't even have any pics from that show either. I just dropped the ball I guess.
