This is so much worse than the Santa Fe. I've already pulled the engine and trans twice as well as built the engine twice.

I found a broken vacuum line inside some loom that was causing the EGR code. The coolant temp was working but the connector was a little loose so I crimped the connectors a little and that took care of that code.

I emailed Steve this morning and just heard back. I have an appountment to have the Cobra tuned tomorrow at 1pm. I'll post up the results tomorrow.

So I have good news and bad news. First the bad, we were not able to complete the tune due to maxing out the MAF at about 5200 rpms. I have an 80mm Lightning MAF and need to go up to a 90mm. Luckily Guy had an extra 90mm housing so I already have that. I just need to get the elbow and filter adapter for it.

Now for the good news. With Steve stopping the pull at about 5400 rpms the car still made 455rwhp. It made peak torque at 4300 rpms which was 474rwtq and at 5200 it was making just over 460rwtq. Steve said there is still some more in it because he's pulling a lot of timing out above 4000. He thinks peak will fall right between 470-480 on the pump gas tune and thinks that it will make 520rwhp and 500rwtq on race fuel.

I quite literally live in a sea of mustang parts :/

Now if you can just remember where you put everything.

Shaolin Crane 03-19-2013 09:41 PM

I have a loose recollection of where everything is.

I have an issue ever since I put the engine back together that it has been using oil. A lot of oil lately, like a quart every 700 miles. I thought that maybe the intake gasket was leaking because I reused the gaskets. I was going to wait until I finished Andy's car before I tore it down only because I am also going to be installing a new cam but I decided to start on it today. I started pulling it apart and the intake gasket was leaking which I'm happy for but I also found sludge built up in the rear water passage on the head. I reused the head gaskets as well and I think they were leaking too.

I needed to finish lapping the valves on Andy's heads so that I had room on my work bench to put my heads. So I stopped working on the Cobra and finished Andy's heads this afternoon and then went back to pulling the Cobra apart. I finished around 7pm tonight but didn't take any pictures. We're supposed to be getting the crank, bearings and rings either tomorrow or Tuesday so I'll be building Andy's engine at night this week and then installing it this coming weekend. After that I'll get the cam changed in the Cobra and then pick up new gaskets to put it back together. I also have every thing I need to install the 90mm MAF except for an air filter so hopefully once I have it put back together I can get it to Steve to have the tune finished.

I have an extra 4" filter if you need one. Do you mind if I have your old 80mm housing for the race car?
