It’s alive (again)!

A little while back, I blew the engine in my 06 Solstice (toy track car). A vacuum / boost reference line running to the wastegate worked it’s way loose (I really need to buy stock in LocTite), and, in an episode of spirited driving, the turbo went full-boost.

That means about +30PSI, as opposed to the +7PSI that I’m targeting.

And, the result:

Good times.

In the process of replacing the engine, I installed a full set of DDM braces (strut tower, rear cross member, backbone/driveshaft closeout panel), a Spec aluminum flywheel, and Wilwood 6-piston, 14″ front brakes. (The rear 4-piston FLS set will wait until I figure out a parking brake solution.)

It’s still blowing white smoke out the exhaust. Since I’m not losing any coolant or any other fluid, no leaks, etc., I think it’s just burning off what’s left from when the original engine blew.

Word to the wise: check your harness grounds! We spent the better part of a week chasing what turned out to be a loose ground in the engine bay fuse block.

 

It’s alive! Alive, I say!

We finished up the Werks Stage 1 turbo install over the holiday break.

Holy crap, this thing is fast.  HP Tuners is showing 23 PSI max manifold pressure, or around 8-9 PSI of boost (given ambient atmospheric pressure of 1 bar or 14.5 PSI). I had a CEL for a day and a half, but it’s since disappeared.

The (otherwise stock) car now spins the tires under WOT in second gear, at just about any RPM. HP Tuners shows a 0-60 time in the 5 second range, which is a huge improvement.

Fun part: when we started the car for the first time, it revved to redline for about 30 seconds, then almost died, then revved back up, then down, and eventually settled on a rough idle around 2k RPM. My best guess is this was the ECU trying to figure out how to deal with the larger fuel injectors. Of course, after reflashing the ECU with the tune I received from Performance Autowerks, it calmed down quite a bit.

There’s still some pretty bad hesitation when going from cruise to WOT, and I’m in the process of iterating the tune with Dave @ Performance Autowerks.

(BTW, Werks is a great company – very helpful, responsive and professional. I recommend getting your next toy from them.)

I’m planning on taking it up to the dyno in McKinney once the tune is a little more dialed in.

Engine-driverBack to work!

Solstice 2.4 Werks Turbo Install

I picked up a 2006 Solstice 2.4 NA a few weeks ago for use as a track and autocross car. It’s a great car – light(ish) weight, awesome suspension, 5 speed (6 would’ve been nice), and, of course, it’s a convertible which is always good.

My only complaint is that it is a little underpowered. The stock configuration only makes about 177hp (or about 140whp), which is just unacceptable. Having to shift from 5th to 3rd to pass on the highway is annoying. My daily driver – an 06 G35 coupe – makes a little over 300hp at the crank, and it’s my kid hauler.

So, what to do?

TURBO TURBO TURBO MUAHAHAHAH

(I’d rather to an LS1 swap, but that’s going to have to wait until my toy budget is replenished.)

So, I picked up a second-hand, but never installed,  Performance Autowerks (aka, Werks) Stage 1 300HP kit  from eBay for much less than retail. Between the price of the car and the turbo, I’m still many thousands of dollars ahead of where I’d been if I bought a stock GXP.

My Dad and I spent last weekend tearing the car apart and getting about 90% of the way through the installation. Unfortunately, I left the instructions at home in Dallas, and his shop is in Oklahoma, so we just winged it.

Here’s the car, sans some components:

Our last child, and the first girl. Hopefully she’ll wind up looking *something* like me, unlike the boys.

Hopefully this explains why I’ve been so busy, and the blog has been silent.

Also, Wyatt started kindergarten yesterday! We basically dropped him off at school at 7:30AM (remember when school started at 9:00? WTF?), went back home to grab a few things, then headed to the hospital for the delivery.

Crazy day.

In other news, since getting RIF’d from ARM at the start of June, I’ve interviewed with:

Google (I am NOT moving to California, and the Chapel Hill office is small enough that hiring is rare.) (Note: PLEASE do not ask me about the interview questions. They were nice enough to fly me to Mountain View, so I figure I should respect the lengthy, excruciatingly-detailed NDA I had to sign pre-interview. Also, I have no desire to be sued.)

IBM Watson Labs (well, kinda – there was a lot of portfolio talk and I got to interact with some seriously smart people)

… and a local game company that shall remain nameless until I receive the results of the seven hour(!) interview I had last week.

This is actually a great time (personally) to be unemployed. I get to pick Wyatt up from school, spend a lot of time at the hospital with Audrey and Gwen, and, in general, do all the things I want to do.

Life does not suck at the moment.
