The JefeFD - Jordan Innovations' LSA/YSi FD Time Attack Car

Sounds amazing!  GL with the M!  I almost bought one but it broke on the test drive LOL  Idles fine but went into limp mode for some reason.  Can't wait to hear more about the drivability of that COPO.  I really wanted one of those but ultimately built a 434 with a little more mild cam.

Thanks Kinger!

I’ve been around the Macs since 12C’s hit and have a few of friends who’ve been in and out of the cars over the years, and a couple that are hardcore into them - breaking on the test drive is hilarious (at the point you’re thankful it broke right then, right?), but things do happen and I’ve got a good group of people that know how to do everything.  Hard to avoid getting raped on parts costs, but they made thousands of 720’s so I’m bullish on being able to roll with the punches.

I’m more optimistic about driveability of the COPO engine after seeing it start+idle - I drove the race car these came from (Conrad Grunewald’s Formula D Camaro) a few times and wasn’t a fan of needing to tach it up to 4k rpm to get moving haha, but that car had a different ECU, tiny button flywheel and a spool read end with sticky tires.  It did rev incredibly quickly though and from 4k-8k rpm had a very fun powerband (especially with the n2o 150shot it had for some tracks haha).

I’m *hoping* mine will drive more like a normal cam’d v8 with my ACT twin-plate (~30lb clutch and “lightweight” flywheel) and a non-locked rear gear.  We’ll see today?!

Got my steering stuff in - needed a custom Woodward steering shaft setup that I’ll document a little later due to relocating steering rack a smidge to clear the LS7 dry sump pan, and it fits beautifully.  Going to put new rack boots on and get ‘er on the ground today hopefully!

I mean, I'd do it too, but I'm an idiot.

Update after some more time on the car today.  Finished putting rack boots on and bled the brakes, so wheels could go back on.
First fit-up of the new dry sump tank and booooyyyyyyy is it close to the tire (275/35/18's currently, other tire is a 295/30/18 that's very similar).  About 1/16" of daylight between the tire and the lower clamp, so will keep an eye on that as I start driving it.





Also had some fun with the power steering setup - I've enjoyed a Turn One pump and Variflow fitting with the blower setup (which ran 5th Gen Camaro accessories), and realized that neither the pump, reservoir, pulley, or brackets swap over haha.  So I bought a Turn One Corvette pump and swapped my Variflow fitting over... except I couldn't figure out an exit direction that worked.  Tightened all the way down it wants to point forward into the pulley.

Ended up hogging out the bracket below/behind the pump and making a shim/spacer so the Variflow fitting could tighten down pointing aft, and run a 90* 6an hose end down to the rack.  The pulley baaaaaarely clears the fitting, but it looks like it works and didn't leak (yet)!




Got it running long enough to warm up the oil and the water (takes FOREVER to come up to temp with the oil-to-water heat exhanger) and tightened down a couple fittings that looked like they might be contemplating leaking, and was thoroughly happy that all the accessories are on and everything looks good.

Wife safely filming the warmup - couple free-rev's in there, tiiiiiny throttle shoots up to 4k rpm instantly.  Sexy.

Exhaust looks terrible, but I've got some more 3" stainless and will hook that up next and try and terrorize the neighborhood a bit
