It should not matter what the relationship is on inlet side since no carb will be mounted there... the oil feed and drain might limit the orientation.

NeedPart - #17 in diagram Trying to seal up the engine compartment during these hot summer months. The left side shield I have is rusty at bottom corner and seal pulls away from body. If you have one in real darn good shape, let me know. Otherwise I'll start calling our esteemed vendors. Thanks.

This graph is an attempt to demonstrate how the carburetor venturi flow compares to the different turbo intake sizes. Comparison is at WOT. The Carter YH flows just under 150cfm vs the F-flow turbo intake at approx. 430cfm. The classic Stromberg WW 2bbl upgrade provided nearly 320cfm flow for a nice increase in boost. Dick Griffin is credited with developing the Stromberg WW kit to increase b

Used this crude get up to remove an aluminum tube today. I have no defense for my actions except had no alternative on hand. The tube did not get scratched at all. Vice grip was finger tightened over the split rubber hose and only snugged enough to twist the tube (the vice grip was not pre-tightened and "clamped")... Then palm slap to pop the end out of the block.

The testing continued this past weekend with very good results except for this jagged kPa vs rpm curve under boost conditions. The video camera was set to 60 frames per second so I was able to see rpm climbing and record kPa. This just ain't right is what I thought. As the old saying goes... "two minds are better than one". My discussion with Kevin pointed me in the direction of t

Continued fine tuning has resulted in this new timing map... "the trench". This concept came about after reviewing some video where I recorded the kPa vs rpm during a few strong boost runs. After seeing the boost vs rpm curve the timing map was fashioned to keep 28*-29* along that same curve. If the rpm is below optimal when hitting boost, the timing falls off into the trench to create

That logic sounds valid... but I won’t try it though as I don’t want or need more than 40deg total advance under light loads above 4000rpm Not doing much cruising at 80mph these days

Specifically for the Black Box, the electronic dwell circuit can only provide up to 40* total timing for the 6 cylinder application when rpm is 4000 or higher. At lower rpm the circuit is ok providing up to 44-45deg total advance. The reference signal for the BB is 0*

This is the 'wild child' beta test version of optimized timing. This is based on the static timing curve from the Custom 18* distributor with a few degrees of timing added above 3800rpm.The solid bold line indicates base timing at neutral manifold pressure here at sea level. These unique characteristics can not be accomplished with a distributor or parameter based timing... only tabl

CB Performance sells the black box and has sold many to the hot rod VW tuners. There are at least 5 Corvair guys that have one as far as I know. The Black Box is selling for $199.95. It has on board MAP and wiring is straight forward

The standard distributor can be considered a 2 dimensional device that controls timing with mechanical advance based on RPM and vacuum advance or boost retard (turbo) to alter timing based on load. Here are a few factory advance curves to compare the start RPM and the rate of advance. Specifically for turbo engines, Dale Manufacturing created the advance/retard unit that added vacuum ad

Clay- It looks like your load kpa table for vacuum advance is upside down. Then adjust your max advance to be 40-42* at light loads and it might look better.

"Go Rich, Add Advance". You can try a more aggressive timing curve using another 67 distributor - the 1110330 140hp MT version. As you can see, the mechanical advance is all in by 2800rpm vs 4200rpm for the 95hp distributor. The limit of 18* mechanical advance on the 330 also allows you to set static timing a bit higher without getting above 32* total (regular pump gas).

Dave- This diagram (for '64) shows the individual parts that are used for redirection/control of hot air flow. sometimes they come assembled with all the parts, sometimes not. Lower shrouds (11 and 29) Exhaust duct parts (9,10,12,13 and 28,30,31,32) as well as the thermostats and actuating rods (6, 26, 27).

Revs will get you into the boost, but not much unless you go past 4000 and push up to 5000rpm or 5500rpm. Take a look at the HP vs RPM curves along with timing. Based on stomping gas pedal at 2500rpm to start developing boost, the engine will lose timing (when retard kicks in) until well after 4000rpm. and as Spyderman64 says... blowing out the carbon will help power.

Perhaps some insights from another early 60's marque will benefit this discussion. The 356 S-90 had a rear camber compensator. This description below is quoted from a long-time 356 race car builder/driver Vic Skirmants. The bold emphasis is mine. My '62 Spyder has a '64 rear suspension. Currently no front antisway bar is installed and it's fun to throw into corners. "
