EDIS Adapters for B21/23 Engines

For the Volvo enthusiast that plans to convert the fuel system on their B21 or B23 powered car to electronic control utilizing a system such as Megasquirt, Avalanche has developed an adapter that enables one to mount an EDIS trigger wheel on the front pulley. As with our wheel spacers, these adapters are CNC milled from 6061-T6 aluminum alloy. They too are available anodized or bare.

$125.00 USD anodized.

Underdrive Pulleys with EDIS Adapters for B20 engines

 

More from necessity than demand, we have developed an underdrive front pulley with an EDIS adapter ring machined into the front. We built this unit for the '67 122s project car as we are running a Megasquirt system to control fuel and spark. Obviously has the performance gains realized by utilizing an underdrive pulley but also gives one the option of running programmable spark control. Machined from billet 6061-T6 aluminum alloy. Can be anodized or bare aluminum.

$125.00 Special order only

$200.00 Double Pulley, special order only.

B230 Underdrive Front Pulleys With EDIS Adapters

In conjunction with developing the B21/23 EDIS adapter, Avalanche has developed an underdrive front pulley that also doubles as an EDIS adapter for B230 engines. While many buy this item to adapt an EDIS trigger wheel to enable programmable, electronic control over ignition, others are buying it simply because it is an underdrive pulley and they recognize the advantages of running an underdrive pulley even if they have no plans to modify the ignition system. This pulley is also milled from 6061-T6 aluminum and comes anodized. Because it works as a pulley, the anodizing serves as a protective layer from the abrasiveness of the belts and ensure longer life expectancy.

$225.00 USD anodized.  In stock.

Short-Throw Shifters for M46/47 Transmissions

We modify stock shifters to mechanically shorten the throw. Typically the throw can be shortened from approximately 6" to approximately 4". Actual results may vary depending on the condition of the various bushings related to your shifter. New bushings are still available through the dealer and are relatively inexpensive. If you are replacing your stock shifter with our unit, it is strongly recommended that you replace your shifter bushings as well. Because this is a short throw shifter, nothing above the pivot ball is modified, meaning the reverse lockout still works and the standard shifter knob remains.

$75.00 USD.  In stock.

Adjustable Camshaft Gears

We have developed a process where we take a stock camshaft gear and drill additional holes to offer the user a variety of settings. The standard adjustable gear is available in a 6 degrees advance to 6 degrees retard range in 2 degree increments. For users wanting more advance, a gear that offers as much as 12 degrees advance can be custom made. We are also able to drill 16v round tooth camshaft gears, although our supply for those is limited. 


$60.00 USD for square tooth gears.

$70.00 USD for round tooth gears.

$125.00 USD for a pair of round tooth 16v gears.

Round and square tooth 8v gears currently in stock.

A-cams and K-cams

We try to keep a small supply of factory K-grind and A-grind camshafts in the shop for resale.  The A-cam is a wonderful upgrade for cars equipped with an M or a T grind cam.  It has a nice broad powerband that works very well in both turbo and naturally aspirated 8v Volvos.  The K-cam is much bigger and better suited to people who want a higher and stronger powerband.  Typically they begin to make power above 3,000rpm and hold it very strong until the factory 6k rev limiter, or even higher if you choose to go there.  An adjustable cam gear clocked at 4* or 6* advanced brings the powerband down to a more streetable level. 

$85.00 USD for a K-cam.  $125.00 for a K-cam and adjustable timing gear.

$65.00 USD for an A-cam.  $100.00 for an A-cam and adjustable timing gear.
