Quick walk-through of that car show. I'll have 1/4mi race prep and in-car footage put together soon.

Got out to the track last month. Ran in street trim, and on slicks, to get the dust off. Been 11yrs but got back into 11's, for now. Video with details should be put together eventually, but been busy at work.

Made a prep video just talking thru as I got it ready for that Test N Tune last month. Some random tips/notes sprinkled in as I narrated my thoughts along the way.

Race video will be edited together from GoPro in-car footage this week. (more entertaining than this stuff, but I'm sharing the steps along the way)

Fresh 2004 GTP engine in after spinning a bearing at 7k rpm in the 2006 block during the May track trip (picked up the engine the next week, but got busy this summer). Videos uploaded last month or so.

Added (either due to oil issues, or to improve runs):

• ZZP oil pressure kit
• ZZP 3500 stall (was 3000)
• CX T72 BB .68 A/R T4
• ZZP lifters (LS7 style)

T72 T4, T67 T4, T66 T3/4

Video will be made soon, but I realize I didn't post the last couple, so feel free to see them on the channel link.

Hoping to hit the same track in 2wks, then maybe a couple more outings before the end of the year.

Got the car running, and just putting some local miles on it (commute and store trips), so I can work the bugs out.

Wanted to hit the track here in VA tonight, but rain delayed that idea, so I'll get more ready with higher boost tuning for the next chance.

I guess the new setup was too much for the flex to handle...

I knew it was a little loud, and I feared that a weld on the new 3" Stattama pipe/wastegate already cracked (see my Z7 kit that had this common issue among stainless turbo stuff that gets hot). Changing the engine angle with the shorter dogbones for lower coilover use, and cradle spacers for hood clearance may have played a big part, too.

That also explains why my Wideband O2 6" below this flex is reading lean everywhere but full throttle. Oh well, guess I'll have to set aside some bucks for a replacement downpipe, or this is an excuse to track down a local fabrication shop that does TIG for a new flex on this and the repairs for the Z7.

Guess I haven't updated for a while. Was busy overhauling the GXP and F-150 before moving cross-country and getting into a new-to-me house.

Latest update is that I've driven the Regal a bit, but it had a high idle/squeak, and needed some DIY alignment adjustments after I messed with the coilovers a bunch.

After doing a homebrew smoke test, it looks like I need to reseal the intake or injectors, so I decided to swap back to the L26/HV3 setup. (Really just wanted an excuse to prep the Holden intake for cool appearance mods.)

Also doing some tweaks on the vac lines and intake pipes for clean-up to make it easier to work on and look a little nicer.

Also, since I'm back in the Midwest corn country, I may finally do the E85 conversion (only 91 here, too). Currently have a Walbro 255, 60# Mototrons, and a 4.0bar Bosch regulator that loved going up to 26psi on race gas. We'll see how much that setup can deal with on E, but I'm guessing I'll be upgrading beyond that system soon.

Ya, a few hours SW of you guys. I'll hit up some meets/events your way eventually. 1320's Ice Cream Cruise is here in 2 weeks, though.

It's pretty weaksauce. Haven't turned it all the way back up in forever, either. Maybe the corn will let me crank the dial and leave it, rather than tap-dancing between 93 and race gas settings.

 

[dezldave961]

It's probably going to be stupid hot here (95-100+), still, so I'll skip standing around an asphalt track to stare at cars this weekend, unfortunately.

In the meantime, I've just finished swapping back to the L26 UIM setup. Had to space my N* TB adapter 3/4" further out to fit past Stattama wastegate, and still had to remove cruise for now.

Runs alright, but chasing a small vac leak and A/C isn't happy, yet. I can tell the good torque (Holden) vs. top end (L26/HV3) difference immediately with the butt dyno. This is meant to be used at the track, though, so I'll save the other intake for when I decide to leave it back in street-only use someday later.

Thanks, it's been a good distraction to overhaul it the past couple years. We built it nice in 2009, and I finally got the chance to just keep making it more like I want for a finished product.

Still bugs to work out before I get to start putting many miles on it for the coming years, but it's close and works for occasional work commutes at the moment.
