The Twin Turbo Nova Project

So, previously I acquired a pair of billet 72mm turbos to replace the cast 67mm ones that died. Teardown of the 67's The Teardown: Teardown of the 67mm turbos showed that the passenger's side turbo was oil starved. Upon closer inspection, I realized that the oil feed adaptors I was using were actually oil restrictors. On top of that, the passenger's side one was clogged with only about 25-30% of the oil flow able to get through. I believe the source of that clog was from when my Fram oil filter came apart and sent parts of the paper element throughout the entire motor. So I am actually pretty impressed that the turbo lasted as long as it did. Most of the damage was to the bushings within the turbos, which ended up depositing most of the material onto the turbine shaft. The Rebuild: I wanted to save these turbos, as we are building a turbo LM7 to put into dad's 67 cutlass. So first was to see if we could get the turbine shaft back into spec. First step was to mic out the...

There have been a few updates we've made to the car recently that are turning out pretty nice.  First off, while driving home from a friend's house, I noticed a bit of a whine that only occurred under load. Along with this whine, I noticed that the car was not making much boost at all. Once I got home, I inspected the turbos to find this: The turbos we bought 7 years ago have decided to sacrifice their bearings to the gods. These were just cheap turbos we got off of eBay, and I really only expected to get ~10k miles out of them. Sadly, they made it about 2,500 miles before giving me the finger. So, I'll introduce you to the latest addition to our family: twin VS Racing billet 72/65's! These new turbos are configured a bit differently than the old ones. Despite having a larger compressor, I configured them with smaller exhaust housings. The old turbos were ar .86, these new ones are ar .68. This should bring a noticeable reduction in turbo lag.  There is quite a differen...

It has been quite a long while since I last posted. I do have a good reason for it too! Luca playing with Riley Shortly after my last post on here, I had my left shoulder replaced (though I was not even 30 yet!). Then exactly one month later, my youngest son was born. So the incision from the newly replace shoulder was not even yet healed by the time I was feeding, burping, and changing the diapers of my new hansom little bug. So working on the car was not going to be happening for quite a long time. During my down time from the Nova, I worked on all kinds of programming projects.... NovaOS for the Netduino in the Nova, LucaLimit (another netduino project that physically limits my oldest son's TV/Video Game time by killing power to the devices via a web interface), BabyTracker (a baby related event/data tracking system), and numerous other private and open source projects. The NovaOS project has come a long way though. The Bluetooth communication layer is complete (tho...
