Big LS motors really are savage in a lightweight car, had the pleasure of driving a c6 Z06 pretty extensively. Nothing prepares you for how well they breath past 5500rpm. Looking good.

After a few months of dividing myself from anything car related, back with a quick update.
First off, I changed the format of my website because keeping a blog style was too cumbersome. The new style will let me post my usual updates in a quicker fashion. The old website is archived but many of the pictures in this thread will no longer work.
Grand Mighty
Switched out the Autopower roll bar for this Samberg piece over the Winter. I had them give the piping a semi-brushed finish on the lathe before welding. The roll bar was then clear coated to maintain that raw metal look. Welds were done in stainless.
Next, got the car dyno tuned.
Video of one of the pulls:
Dyno results:
After a meticulous 2 hour tuning session, the car pumped out 427 RWHP and 429 lbs/ft of torque. Not bad for what is essentially a stock, factory engine with only an exhaust and intake.

I always love your updates. The roll bar looks amazing. I was gna contact Larry at the Raceshop in the future about a bar but may be contacting Samberg instead. I assume they can make another with that jig they've got.
nice numbers too.
Off topic but Do you have smaller rear wheels on the dyno?

Probably won't hear much about it, since I'm too lazy for that kind of stuff

Quick update...
Changed the ignition switch because the car was having some click, click, start issues.
After the change, starts are immediate most of the time. One time the old issue did come back, so I'll need to see if it still persists and then start investigating the relay.
Changed the oil:
And more importantly, I brought back my website and plan to refocus on updating it.

Yeah that shop is spotless. Everything in there was brand new, including that Hunter rack! In floor would've been cool, but the guys had a set of extension ramps that made driving up easy.
More updates hopefully soon. In other news, I redid my website: Grand Mighty

Finally, with the heavy lifting done, attention could be turned to the smaller stuff and working out the bugs. Goal is to get the car driving and performing at 100% without issues that could be passed off as "quirks".
I brought the car back to Marcus Fry Racing Enterprises to get these ironed out.
The priority item on the list was to resolve the clutch’s feel. There was a dead zone at the beginning of the clutch pedal’s travel and the engagement point was too low for my liking. Marcus played with the bore and pushrod of the master cylinder and re-bled the system with the car tilted at a severe angle.
This worked because the difference was night and day. ZERO dead zone and the engagement is near the top. Resolving this really transformed the driving feel of the car.
Next, the holes in the rear wheel well left behind by the old Auto Power roll bar were welded up.
New fuel line and brake line holders to replace the stock ones underneath the car.
Old:
New:
A combination of overzealous freeway runs + crappy California roads led to the flattening of the driver side headers. Patched them up with SS plates.
