I need to do some rule diving again... moving the wing back might help, but C3 Corvettes get nose light - so moving the point where it's pushing down further back might not be a good idea on the track.... wonder if they'd notice if I swapped struts between the track session and the autox.... |
well, look what's back?
https://i.imgur.com/TBXMJg4h.jpg dark bronze https://i.imgur.com/70Syb4ih.jpg fuel cap too https://i.imgur.com/T2ebVsuh.jpg I like. a lot https://i.imgur.com/kJ9Hqhyh.jpg truly better then I expected.... I thought I went too dark https://i.imgur.com/CxdmyFPh.jpg with the wing in place https://i.imgur.com/olBY9k5h.jpg |
a bit done tonight
more fittings - most important is that stainless one https://i.imgur.com/tMf7JcDh.jpg the problem is I welded a pipe fitting for the return when I needed an AN one... oops... will use it as a vent https://i.imgur.com/zFIBeUah.jpg and welded https://i.imgur.com/lotX6oeh.jpg in other news, I'm a really bad influence.... the red Corvette owner has bbc plans :) https://i.imgur.com/BI0f9HEh.jpg |
I think you picked a good color with the rims :thumbsup:
|
Looks great!!!
What color exactly are the wheels? I'm looking for a titanium/bronze color for my centers. Assuming they are satin cleared as well? |

Spoiler is supported by the frame... I also put window glue in place to keep the warp and vibration transmission to a minimum
https://i.imgur.com/PBuKL2ih.jpg measuring done, time to make the tank support https://i.imgur.com/4VyOMYoh.jpg keep in mind I was about 150 lbs light for where I'm racing.... I'll probably gain 30 or 40 lbs in this... all on the correct end https://i.imgur.com/41BWO5Eh.jpg https://i.imgur.com/nk1HQETh.jpg framework installed https://i.imgur.com/MVeSTIuh.jpg not in love with the straps, however, I plan on supporting the defuser off them - so function trumps form https://i.imgur.com/wKSaKYkh.jpg up the tank goes - the metal duct tape was put in place to keep the fiberglass from sagging when I filled the holes for the luggage rack https://i.imgur.com/uzsDJASh.jpg very close - I wanted to make it solid but I wouldn't be able to get the fuel pump out if I did https://i.imgur.com/aOanwENh.jpg last test fit, next up with the fill neck, lines attached, electrical attached and rubber protection on the metal bands https://i.imgur.com/hlfDYEsh.jpg |
Splitter material... best source?
|
a little further
wheels with tires on them https://i.imgur.com/jeSZkNch.jpg cut down the fill neck so I can use a flexible rubber hose for the offset https://i.imgur.com/3EeXqeEh.jpg padding/rubber top and bottom https://i.imgur.com/zx8Tg4Gh.jpg getting close... waiting on a fitting and the fill hose https://i.imgur.com/zDH04cLh.jpg |
it runs again...
https://i.imgur.com/5BZ5wZ2.jpg interior is back in it https://i.imgur.com/PSWXy1m.jpg next up? front stuff https://i.imgur.com/zqSW4dl.jpg looks all buff in the back.... but more to do...thankfully, this isn't a take the car mostly apart deal https://i.imgur.com/YpF0RWP.jpg also need to program and do weighing |
time to weigh
https://i.imgur.com/QX3YgBkh.jpg oh and I'm done with this argument.... the weight of a BBC powered C3 Corvette... 7 gallons of fuel in the tank https://i.imgur.com/K6izgAAh.jpg - something cool, if you look next to the weight numbers, it tells you where the weight is on the tire... didn't realize that - outside has a hair less weight then the inside of the tire which does create a problem since 3200 is the minimum weight.... Optima weighs after the track sessions - the problem is 20 gallons is 120 lbs. - and without the driver (darn, my non-fitness program would finally pay off).... 30 minute on a track at high speed will burn more then 3 gallons..so I will be adding weight so with that bad news, I figured I'd fix my window alignment https://i.imgur.com/l3feqXOh.jpg is 'fixed' the window won't go up again with the switch? oh good lord. https://i.imgur.com/PSWXy1mh.jpg but it seems fixed as far as sealing - however, I'll be verifying this before I put the door panel back on that's enough for tonight *oh wait, cue dramatic music... the rack has a small leak - it owes me nothing because I bought it to use to mock up... it worked so it hasn't been changed. It might be the fitting but just one more thing.... lordy. |
sight and sounds

time for some CAD work
https://i.imgur.com/49uG6qvh.jpg half and half? https://i.imgur.com/tUEP5kwh.jpg there are times when I want to troll... this picture is for those trolls https://i.imgur.com/zose38hh.jpg and more of the left https://i.imgur.com/oVwLSplh.jpg on the other hand https://i.imgur.com/rv49PI8h.jpg |
tonight's fun, working with aluminum and plastic
https://i.imgur.com/joNCvMlh.jpg HDPE https://i.imgur.com/3oBvwQRh.jpg it is Plastic Fantastic, after all... |
onward
time to start fitting https://i.imgur.com/Mmzwanvh.jpg easy so far https://i.imgur.com/LbXb37Hh.jpg now getting harder https://i.imgur.com/LXKOSjZh.jpg look at the top edges, as I start making the spoiler follow the side-to-side changes (it goes flat in front of the tire) that pulls the top in.... I also have to radii the part which follows the wheel opening. I suspect there will be more then on attempt at this.... and all of this to get hate from tracks because it has neither ABS no traction control... and as a bonus is not quiet.... ah well, if it were easy.... |
narrower
https://i.imgur.com/b0vtQcVh.jpg reality is I didn't like the extensions - so I narrowed it https://i.imgur.com/8oB3qhzh.jpg welding mounting tabs https://i.imgur.com/CriMSylh.jpg there is a danger to being on the ground.... https://i.imgur.com/J4yAcnQh.jpg not sure how much of this I'll use https://i.imgur.com/AhZyYfMh.jpg mostly held by tabs https://i.imgur.com/483jLKFh.jpg in other news, another BB for another C3 https://i.imgur.com/8r83f3Ph.jpg and aluminum heads https://i.imgur.com/ir89Jech.jpg I know this is sacrilege in some circles, but if you can fit a BBC, you can make remarkable, NA power for relatively cheap. Not just that but ocean flat and ocean wide torque. LS is a fantastic motor, I have one in Buinicorn, but if a BB made sense, I'd even swap it for one in it (I have one, just not for it) |
getting there
https://i.imgur.com/W6r5B8bh.jpg then comes the make it stay https://i.imgur.com/cg7mq35h.jpg |
blanking plate to direct air to the radiator
https://i.imgur.com/rVsICXhh.jpg metal https://i.imgur.com/hNlb0cCh.jpg installed-ish https://i.imgur.com/oBoncneh.jpg welding aluminum is so easy https://i.imgur.com/NFWreN7h.jpg getting closer https://i.imgur.com/kmu1wkRh.jpg https://i.imgur.com/JgdE3tah.jpg now to decide how much splitter... the blue lines are potential cut lines https://i.imgur.com/fzEMOQhh.jpg https://i.imgur.com/NN4fcC9h.jpg |
for now, the splitter portion stays off.... I want to test like this - I also have a few other things to do to help with air management and rear brake cooling
and more fitting, but this time with a grinder https://i.imgur.com/csAEuvph.jpg it will be black when it's done - but I still have a bit more welding to do https://i.imgur.com/UXVlWOCh.jpg |
brake air intakes
https://i.imgur.com/el72wdvh.jpg here they are.... not going to use them https://i.imgur.com/9W4JkTOh.jpg the issues are too wide and they aim down.... and take up a lot of room https://i.imgur.com/dxhA2Glh.jpg so just holes https://i.imgur.com/ebafiowh.jpg was planning on these at the wheels but they'll work quite well here https://i.imgur.com/NYeA1NGh.jpg some 3" tube to aim the flow at the rotors https://i.imgur.com/y7QzAekh.jpg paint the blanking plate https://i.imgur.com/Osbd8Hfh.jpg https://i.imgur.com/BugloQCh.jpg |
another track day completed.... I had the Cadillac airborne.... so much fun (and yes, I knew I'd go airborne)... did a nice 100 mph 4 wheel drift... nothing to see here, moving along ;)
in other news, painted the spoiler https://i.imgur.com/FIiGfdWh.jpg https://i.imgur.com/zykoG1kh.jpg and installed the block https://i.imgur.com/eGP43Hch.jpg Soooo, next Friday, I'm doing a Track Night in America at Portland International Raceway.... but forecast has snow in it. Granted, it's supposed to be 'just' rain by Friday (the weather witches are just guessing) - however, that's not better because rain cancels.... and honestly, that 2 1/2 mile track would be nothing but standing water and stained underpants if it was doing anything but mist..... I really want to do this track night for a couple reasons - 1) it's where I'm doing Optima this year - thus it's like a free practice, but then 2) noise. I want actual data on noise. I think I have it solved - but the 'if it's not' is I'm building new sidepipes with a far different design... and that will take a solid month to build... I plan on doing this next winter - it will have oval exhaust because Chad (old timers know this story).... but the benefit of new headers is I think these 4' primary pipes destroy power... next winter I plan on building headers/sidepipes that make power for the revamped motor. Also put on port EFI.... now is 600 hp, next up is 900 but more importantly, a wider power band (more rpm) - which pretty much demands custom built headers. I know this might surprise you, but I've built more then a few sets of custom headers - I actually really enjoy doing it. |
it looks nice
https://i.imgur.com/sBVEI6dh.jpg https://i.imgur.com/Qcvs3Jih.jpg too bad it's too low https://i.imgur.com/tGJ2D5Vh.jpg ugh. https://i.imgur.com/r357rQ5h.jpg https://i.imgur.com/IoMX1t4h.jpg so, it's opportunity. The holes in that valence are a problem for aerodynamics - and it was rightly suggested I block them.... so I will the calculation for cooling is you need 1/3 the radiator surface in grill opening... worst case scenario is I put a vent in the closing panel... the problem is it will be hard to create access for the bolts.... and a bit shorter spoiler.... 3 1/2" was not enough.... the other choice might be to make it flexible with reinforced rubber.... That said, $100 later and the tank is full with - bonus, it's not leaking or smelling.... capacity is 25-26 gallons. oh and we're moving .... this should be fun (3 hours east) |
dangling brake cooling lines
https://i.imgur.com/SC3YBMBh.jpg a start to a new setup https://i.imgur.com/3fM5MIyh.jpg the biggest problem is the spoiler can't hang more then 2" from the angle https://i.imgur.com/FQEfZSOh.jpg laid out a new plate - then the shear wouldn't start.... https://i.imgur.com/UFWarT5h.jpg I'm going to try something... according to what I've read - you need an air inlet that is 1/3rd the size of the radiator. https://i.imgur.com/0RxvHe5h.jpg so basically, I'm going to eliminate the under side holes - however, if it doesn't work, I can simply pull the plate and get flow back.... |
spoiler v2 cont.
https://i.imgur.com/XeiljrQh.jpg what that doesn't explain is I had to diagnose and fix my shear... https://i.imgur.com/4NAsQrAh.jpg tomorrow's goal is make this look less hardware store https://i.imgur.com/72qiKlfh.jpg I should explain that plate comment. C3 Corvettes have terrible nose lift at high speeds (they also have big problems with aero with the vertical rear window - the air actually goes backwards as it tumbles off the targa). If you look closely at any of the race C3s from the day, you'll see a number of solutions to 'fix' the problem.... but the worst part is that air making a change from horizontal to vertical - it literally lifts on the bottom of the hood... not optimal. This is why people delete the front license plate or even put the 80/81 nose on their older car.... for completeness, the tumble issue is why most racers used convertibles - no sail panels, no tumble.... |
|
did some work on this today...
worked on the spoiler https://i.imgur.com/3KX6Zjph.jpg cut the block plate and spoiler out of one piece of aluminum https://i.imgur.com/UFrtzbMh.jpg the bottom inch will be rubber.... https://i.imgur.com/hqqfAT7h.jpg also fixed some cracks because it was finally warm enough to use epoxy https://i.imgur.com/F6vwULuh.jpg |
considering if this is what I want
https://i.imgur.com/un45WgJh.jpg or this https://i.imgur.com/LC6cJ5Kh.jpg in other news, painting inner liners https://i.imgur.com/IaurbmDh.jpg and wiring the reverse light https://i.imgur.com/OIXryvxh.jpg all while waiting for the epoxy to fully dry https://i.imgur.com/wn01q32h.jpg |
beta version etch primer
https://i.imgur.com/JGhUAjEh.jpg installed https://i.imgur.com/T2GkYRfh.jpg rivet the rubber spoiler on https://i.imgur.com/onAagNeh.jpg https://i.imgur.com/RuZonUth.jpg install edges https://i.imgur.com/2jMZiy8h.jpg it's also bolted to the frame through the bottom of the radiator cladding also, rather then hard attach to the fenders, the rubber stoppers will keep the metal in place but also allow it to give if I get too low.... https://i.imgur.com/C7uqcsRh.jpg fun fun https://i.imgur.com/9mPOZHBh.jpg spoiler - wider and remove the lift from the nose (no catfish nose lift) https://i.imgur.com/duNdTcUh.jpg what's left? reverse lights and figure out why the lighter plug isn't working... then it goes in the garage to await its first racing of the season (mid-May)... and that schedule is Spokane May 15ish, and PIR May 27.... Also, need to finish up some things on the motorhome but it's close... oh yeah, and buy 2 houses, a commercial property then move 300 miles --------> way oh and get a puppy this weekend. and commute to Idaho for Buick parts. |
dangerously close to the object I imagined 4 years ago - well, 2 years ago after that Randy Probst guy totally upended what I planned
https://i.imgur.com/seiXluWh.jpg https://i.imgur.com/nkCX8ymh.jpg inner fenders done shop empty. Monday, new project https://i.imgur.com/PlNRxNCh.jpg |
reverse light
https://i.imgur.com/KWyrK7Lh.jpg of course I don't have the nuts for these... ugh https://i.imgur.com/SQ7bbzLh.jpg and more wiring https://i.imgur.com/THDInnIh.jpg |
reverse light plug.... same as any other t-based trans (t5, t56, tko, tkx)
https://i.imgur.com/hC6QzuLh.jpg |
It was a busy night for Trio, had to hide Luigi's ball
https://i.imgur.com/XPmsDjY.jpg yet they are peas in a pod... there is a 6 or so month age difference https://i.imgur.com/bNnCNIjh.jpg back to C3 content I can move the exhaust pipe towards the car. Granted, it's no longer parallel, but I have a thought https://i.imgur.com/55W9iWmh.jpg that it will help deflect noise https://i.imgur.com/DmQK43mh.jpg I'm close, within 1 db... |
I thought mistake, nope... works out to $2 a tube so I'm happy
time to refasten the sidepipes https://i.imgur.com/HMS6v6Eh.jpg even the trim is in place https://i.imgur.com/UBcv7sch.jpg |
autox weekend.... the motorhome, it's beyond slow
and I need to fix the trailer brakes - developed a short on the trip https://i.imgur.com/Nks8bbsh.jpg https://i.imgur.com/fBIQxAzh.jpg looking for a short - and need to replace one tire... https://i.imgur.com/L24lWNTh.jpg I also took the opportunity to repack wheel bearings - this trailer is going to get a work out over the next few weeks... |
wow, the impossibility of getting a rebuilt steering rack for a C5 or C6 is pretty remarkable.... I bought another used one, figure I'll get my current one rebuilt (maybe?)
I only post this as warning - in case others figure 'they'll just pick one up'.... yeah, even my parts guy is coming up with zeros.... |

cold lap the faster laps - well, I need to learn to turn the camera off after each run so the battery was done after this run best was 52s in a really built LS Miata, 55 in my class mine was 61 |
if it weren't for bad luck
this isn't the problem https://i.imgur.com/IG82xHPh.jpg this is https://i.imgur.com/x55Xge0h.jpg if you're missing the issue - the mount tab is broken off.... wasn't in the box. |
It's time to get ready for practice at Portland international raceway and Optima
by fixing a bent bracket I think I may have touched a tree with the spoiler... oops https://i.imgur.com/oc7AoI3h.jpg bracket had to come off (not fun) https://i.imgur.com/HvZsJMrh.jpg and got a repaint https://i.imgur.com/x6wZnQSh.jpg the guy I bought the house from owns a shop with water jet - so he's going to cut out brackets for me. I want the spoiler to move back, but Optima requires that the spoiler be no taller then 8" above the highest point of the deck.... so two brackets https://i.imgur.com/whiQbWeh.jpg measure the highest point with a box top https://i.imgur.com/B4bxzHyh.jpg so these two bits... https://i.imgur.com/c2uYFHQh.jpg |
