MONZORA redux: ‘65 Corvair + ‘94 Corvette mashup for 2019 Challenge

Looks great!

In reply to preach :

I will Google the PNs and see if they're available over the counter. This specific set was liberated from an early prototype vehicle when the production headlights became available.

EDIT: dang, $300 apiece?!?!

Ouch!

Guess I'll have to remove them for the Challenge!

Scope creep is real.

me: sweet! RH headlights are done!

also me: battery would fit there if I cut the back out of the headlight enclosure and trimmed upper rad shroud.

also me: dang, I don't have any angle to make battery tray.

also me: now I need to make longer B+ cable

also me: I'm out of butt splice connectors.

also me: dang, where am I gonna put the kill switch?

also me: dang, I need to make hood strut brackets.

so I'll leave you with this:

So at about 5PM today, this happened:

I guess at this point, with 6 miles under MonZora's tires, I can say something about the driving experience. The modern (lol 20 years old instead of 60) seat is, well, modern, so the days of riding an undamped metal sprung couch are no more. Sedan seats don’t tilt as far as coupe seats, but they slide forward a mile. The huge diameter and thin rim of the 1965 steering wheel are a little odd paired with the 2.5 turn rack, but I appreciate the extra leverage since there's no power assist. Brake pedal travel is a little longer than a stock Corvair, but the master (from a 2008 Impala) is feeding eight 40mm pistons so that is not surprising. Calipers and rotors are mechanically much larger than this car needs, so pedal effort is reasonable even without a booster. Clutch hydraulics are a matched set from Audi A4. Take up is easy to modulate, and effort is far lighter than stock Corvair cable setup.

Car is actually pretty docile around town. Since I revised the cable pull angle coming off the throttle body cam, I'd say the tip-in feels pretty C4-ish. Clutch takeup is better since i tweaked the pedal a little. Shift throws are perfect. Effort is a little high but very direct feeling.

It's not perfect though. Center armrest needs rounded corners and a little bit of padding. Front of seat should be about 1/2" higher, but thigh clearance would be tight on entry and exit. I should have figured out how to keep the parking brake. Currently using a 12" length of 2x4, placed and retrieved from driver's seat.

Datalogs show I haven't exceeded 3500 RPM or 25% TPS. Taking it easy til I have more confidence.

I updated white board last night. It's so satisfying to see zero show-stoppers on the list. 2024 Challenge is going to be a blast.

The 25% max TPS usage surprised me. I thought I cracked it at least 50%.

In-dash tach doesn't work. Add OBD splitter, android tablet, and ALDLdroid app to whiteboard.

EDIT: currently descending into San Antonio TX for an industry conference. No garage updates til Friday. :-(

In reply to maschinenbau :

I mean he's got all the sparkplugs in tight now so it prolly feels like he is...

I hereby challenge you to burnouts in the hotel parking lot for manual transmission gm engine honors.

have you checked that pedal geometry actually GETS to more than 25% open? my duster cannot get above 70% with current pedal geometry for some unknown reason. 

WFO at the pedal may not actually be WFO at the engine.....

Also, wfo for the computer may be anything above 50% and then relies on map, maf or afm.

That's how the 3500 in the racecar works fyi.

Datalog with key on and engine off shows TPS goes from 0% to 97% IIRC, so the only issue is I need to grow a bigger pair.

And no burnouts until after I have a drag time in the books!

Quasimofo was so right about you.

In reply to preach :

Well ..... that is sketchy and scary!

AC:  How are you doing on suspension plans and how the car hiked the inside wheel at the '23 Challenge?  Seems like the car is really coming together.

At 23 I had stock C4 front bar and no rear bar.

I can disconnect front bar.

I can lower rear ride height 1".

I have narrowed the base C5 rear bar.

I'm going to take narrowed C5 rear bar to JY and look for similar shaped bars in larger diameters.

Then I'll have a bunch of combinations to test.

Mad respect. \m/

Driver's side headlights mounted:

It's past noise curfew, so tomorrow I'll cut the back out of the driver's side bucket, same as I did on the passenger's side. Then I'll splice all the wires and back it outside to ghetto aim them against my garage door.

In reply to AngryCorvair (Forum Supporter) :

Lowering the rear ride height should increase body roll, the roll center falls faster than the ride height does.

It will be an interesting experiment, definitely worth it to me to evaluate all options and combinations if time allows.

Are your socks labeled "L" and "R" too..... ;) ?
