Bumpers and the other misc. stuff is painted and back on. Stripped the car down to race trim and threw the slicks and skinnys on. Weight of the car is 2453 lbs with a half tank of gas. Ready for the track and the grudge match with the old man's Z06!


that's sick.. your car is lighter than my blue car and made more hp.. I think I need to change the turbo and a diet soon.
Love the car.... Big thumbs up!
Btw I was stationed at goodfellow AFB back in the day.
I went to the fire academy...Are you military?
This is one heck of a build it was so great I showed my father and he loved it even, and he's a hardcore bow-tie dude. Most unique thing I've ever seen, I applaud your creativity and craftsmanship.

Nope, I'm not military. But I lived about two blocks from the base.

I posted this over on the Nova message board. I'm interested to see the reaction. It looks like most people think it's pretty cool thus far.

Not yet. Hopefully I'll get to the track by the end of January. In the past couple of months, I've cranked up the boost to 22 psi and have added a water/meth setup. I've also tuned closed loop boost control and closed loop O2 control. This weekend, I'll see if I can't add some pics and results of the recent upgrades.

I've been horrible about posting lately, so here goes some updates.......
I finished the rear interior panels. Nothing fancy, but I think they turned out pretty nice and add to the interiors, minimalistic/brushed alluminum motif.

I've been somewhat obsessed with EGTs lately and as a result have done a number of things to even them out between the front and rear and to reduce them overall. To that end, I made a new intake elbow out of a Rotary Works elbow that includes an internal divider.

I also added an AEM water/meth kit to reduce EGTs. I'm running a 50/50 mix with two 315 cc/min nozzles progressively from 11 psi to 25 psi. That's not much compared to some folks on this forum, but my intention is not to be able to fun pump gas, it's a small EGT reduction when running C16. The nozzles are placed, one on each side of the TB elbow's divider, so rotor distribution should be pretty good. At 22 psi, with the air fuel tuned to the same as before with no water injection (11.5 AFR), I'm seeing a solid 55 deg F reduction.
The setup is pretty cool and I have it on a toggle switch (the blue one, red is high/low boost). I have the "boost-safe" line of the AEM controller wired into the haltech, so if there is a problem with the system, or if I accidentally flip to high boost without the water injection being on, the Haltech will switch back to low boost mode.
No water..........

And finally some miscelanous stuff........
Closed Loop Boost Control is working. It's pretty nice because my dual wastegate/single boost control solenoid was pretty sensetive to temperature fluctuations. It also lets me use the low boost/high boost switch and Water/Meth safety switching to low boost, which is pretty pimp.
I also made a new mount for the line lock / launch rev limiter button. The slicks will hold a 5000 RPM on the street, but starts to roast them when you up it to 6000 RPM........hehehehe! It hooks pretty hard. Can't wait to go to the track and launch at 7000 RPM! The tilton flow control on the clutch line seems to do a pretty good job, allowing you to just dump the clutch without shocking the **** out of the driveline.
Closed Loop O2 is working. This feature is pretty cool, and allows wideband O2 feedback to trim or add a bit of fuel when cruising. A nice feature for a bridgeport, where the thing only pulls -9 in/Hg at idle. Not many cells in the driving range!!!
Some track #'s are coming pretty soon. Hennessey is right down the road and rents out there track for a pretty reasonable price. I'm thinking about getting my old man, and my brother together for a little heads up racing. I suppose I could just take the car to Baytown, but I don't see much track time, so it makes me nervous and rushed in the hussle and bussle of things. Having a little private track time sounds pretty good for the shakedown runs. Also, that way when it blows up, I can deny it! HAHAHAHA!
