Re: Steering wheel diagram

65 corsa here. Anybody got an exploded view of what is under the wheel when you pull it off? Manual says something about a spring and centering hub. Arent there. Also, column shakes at top. Sent from my iPhone using Corvair Forum mobile app The 65 model year is confusing since the manual shows the ...

Re: 1963 Turbo ( stock) Spark Plugs

Brad suggestion won't work, unless I missed something. Hooking batter voltage to the coil "+" and grounding the coil "-" will simply show a 12.33 drop across the coil - one load. (if the wire gauge is too small you might get some voltage drop in the wire). An experienced electrical person would inst...

Re: 1963 Turbo ( stock) Spark Plugs

I have to admit I'm not a 64 expert. I do know the Monza harness used a 1.8ohm resistance wire. As you said it's difficult to verify with a standard meter due to poor resolution. Figure if the wire were 1.8 ohm and the coil 1.4 ohm the voltage drop through the wire from 12.33 would be about 6.94VDC ...

Re: Differential

Dan is a great guy; he built my 4 speed and diff. He too can be difficult to get in contact with because he only has a land line and certain morning hours that he answers the phone (I think 8:30 to 10 am). Have to let it ring because no way to leave him a message but it would be worth your effort. ...

Re: 1963 Turbo ( stock) Spark Plugs

OH - you have a 64 wiring harness!! Well that explains a lot. If I recall correctly (folks feel free to correct me). The 64 Spyder wiring harness eliminated the earlier ceramic ballast (special on the earlier Spyder Turbo cars) and went with ballast resistance wire in the harness like the Monza. WIT...

Re: Question: Temp gauge accuracy and proof..

Unless you are going racing the the Corvair oil cooling is not an issue - assuming you have a clean functioning stock oil cooler. Oil lubricated turbo's do tend to have an issue with oil "coking" at the bearing. A common practice is to let the engine idle for a few minutes after a good run to cool t...

Re: Differential

If you are in SoCal check with the folks at South Coast Corsa. Member Dan Drommerhausen does trans and diff work and may have a lead.

Call SCC Prez. Chuck Rust at his business and see if he can help - (310) 679-7443

Re: Question: Temp gauge accuracy and proof..

A few folks have "characterized" the gauges - they don't publish specifics since they use the data to develop modern drivers they want to sell - understandable. What has been stated is the Spyder (EM) and Corsa (LM) gauges used the same thermistor, BUT the Spyder gauge had accuracy limitations and w...

Re: Undercoating

I looked up RAAMat reviews and it is cheaper, BUT - folks complained it was very sticky/gooey and after a few months it came down off roof and vertical panels. Dynamat Xtreme DOES NOT come loose after it sets onto a clean surface - about one day to set . I installed it on my clean and painted roof a...

Re: 1963 Turbo ( stock) Spark Plugs

Your story seems familiar - I run into so many incorrectly configured Petronix installations. The Petronix Ignitor (I) will malfunction if you don't have a minumum of 3 ohms of input resistance at the coil - this is the same input impedance regular points require. The stock Corvair turbo system used...

Re: Undercoating

The Home Depot roofing material has been used INSIDE the car for sound reduction and folks complain about the smell. Cheap, but stinks up the car. The Dynamat pads are expensive, but you only use them once and I've never had a problem with them. There are other sound mats sold that try to compete wi...

Re: Cylinder Head Temp Gauge - 66 Corsa

Glad it all worked out. The gauges are "damped" or put another way the needle armature binds a little. This prevents needle bounce due to car vibrations and with the fuel gauge it keeps the float bouncing in the fuel tank from causing the needle to swing. Sometimes the gauges loose damping due to we...

Re: Cylinder Head Temp Gauge - 66 Corsa

thanks for the info...so it seems at least that I have continuity through the gauge. So I tried what 63spyderd suggested and ground my gauge from that same wire to the battery, and turned the key to on...the gauge jumped to 300, but didnt go any further, and it doesnt go back to 200 now either when...

Re: Cylinder Head Temp Gauge - 66 Corsa

Hi there, So I am having a similar issue with my head temp gauge on my 65 corsa. I took all the advise here and applied it :) The thermister seems to be working fine registers between 1920 and 1550 (there abouts) cold...warmed it up a bit and it goes down to about 620 (just letting it idle in the d...

Re: Cylinder Head Temp Gauge - 64 Spyder

Brad did a great job of covering the circuit and component location. Note that the Spyder temperature gauges weren't as accurate as the LM Corsa guage and the thermistor drifts with age. Bottom line - figure out where the needle is during normal operation and if it start going up - beware. By the ti...

Re: NOS cylinders in GM Boxes

I don't have my parts book handy. The GR 0.30 is the GROUP number. All Corvair pistons were std. AFAIK. DO BEWARE - GM matched piston weights in opposing pairs NOT as a set of six. The NOS pistons (in the cylinders) should have an INK number on top of them for the weight category (not the actual wei...
