Our sheetmetal blower manifolds are not just Pro Stock manifolds with a plate welded on the top. Although the Pro Stock manifolds work well in non supercharged applications the design of the blower manifold is different to accommodate the environment under the supercharger.. Another consideration is that the Pro Stock manifolds are usually 2 or 3mm wall thickness which is OK for that application if you a reworked Pro Stock manifold on a supercharged application the first time that you "sneeze" the blower the port runners will bulge out and you lose all the excellent flow characterises of the manifold. KLRC manifolds are only made for supercharged applications, we do not make Pro Stock type manifolds. We are the experts in blower manifolds. Some of our manifolds have removable top plates that allow changing of the blower type and blower position as well as internal access to the ports.

Chevy Tools -----------------------------------------------------------------------
89800-00825 System One oil filter wrench
This wrench wraps around the filter case and grabs a fin to help spin the entire filter case off the filter mounting. Using this wrench instead of a screwdriver will protect the fins from breaking off the filter case.

89810-00891 Wrist pin checking tool (check for straightness) dni dial
The single biggest cause of rod bearing failure after an engine has been over revved or stressed is bent rod bolts. When you over rev the engine the big end of the rod goes out of round for a moment and when if does causes the rod bolts to bend. The aluminium rod wants to return to shape but the rod bolts being steel want to hold their new shape and are bent holding the rod out of round. When the rod is out of round due to a over rev the sides of the rod big end are held in and out of round by the strong steel rod bolts this reduces or eliminates the normal bearing clearance. This lack of clearance will cause bearing failure resulting in a burnt bearing and eventually a hole in the pan and block. Usually this failure is falsely attributed to oil, the oil pump, the bearing or the rod bolts breaking. If the bearing is burnt the rod bolts did not break first though they may have caused the problem. The destroyed parts are no longer available to check and the true cause is never found. Check your rod bolts and eliminate problems. An easy to check the rod bolt to see if it is bent is to use the KLRC rod bolt checker. Save yourself a lot of money and check the rod bolts.

See the list of other race car tool available from KLRC ask for a tool sheet and we'll send you one.

Header flappers for collector headers -----------------------------

34252-35001 Header flapper 3.5" collector
34252-40001 Header flapper 4.0" collector
What do the flappers do on the collectors? Stop the rocks from going down the pipes when the engine is off and the car is being towed.

Header mufflers for collector headers -----------------------------
34387-35001 Header muffler 3.5" collector .
34387-40001 Header muffler 4.0" collector
Why would you use mufflers on your DYO car?? If your opponent can not hear you coming then he may try to save his dial in and get off the throttle early and you nip him at the finish. This also allows you to start the car at home without upsetting the neighbours.

Exhaust components --------------------------------------------------------
47125-00001 Exhaust thermocouple probe bung 1/8" npt
KLRC can install them on your headers

Header covers for Zoomie headers ----------------------------------
34195-24502 Big Block Chevy header covers 3mm aluminium to suit KLRC headers
34195-25502 Big Block Chevy header covers 3mm aluminium (custom)
Why do you cover your exhaust on the return road? If you don't the sticky tires will pick up rocks and throw them down the exhaust and the rocks will go into the engine. The 351 Cleveland is nearly the worst engine for this problem. Only the SBC is worse due to the angle of the exhaust port mounting.

Electric Water Pump

The KLRC 12 volt water pump is a powerful light weight turbine type pump that pumps enough water to cool any drag race car. We use this water pump on our 500 cubic inch modified dragster and drive the car all over the track because we do not need the tow car to help keep the engine cool. The pump is quiet and draws very little amperage which saves the battery The pump weights less than a pound. DYO racing is about consistency. One of the items that you must keep consistent is the engine temperature. If the engine is too cool or too hot the performance will not be the same causing the car not to perform on it "dial in" and causing you to loose the race.

40577-00001 Radiator

This radiator has aluminium core for better heat transfer and less weight, 1 1/4" inlet and outlet connections and mounting brackets made on the radiator for easy mounting..

40578-10001 Radiator mounting
 
for LOWE radiator on rear engine dragster.  This radiator mounting lays the radiator down over the top of the transmission and hinges up for easy service to the transmission. We have this radiator and water pump combination on our A/MD with a 506 cid Big Block Chevy and the car is driven everywhere at the race track. The advantage here is that we control the heat and this allows us to control the consistency. Another advantage is that is you could go racing completely by yourself since you really do not have to have someone tow you around.

Electric fan
 
40251-10001 12" electric 12vdc Plastic cooling fan with rear guard

40577-00002 Trans cooler

The KLRC trans cooler has -6 hose ends on the connections for the cooler that allows the use of -6 high pressure hose or braided hose for a more leak proof connection. When used with the KLRC radiator and radiator mounting and the fan as a package it makes a tidy easy to service package that swings away for easy transmission service.

Expansion chamber and return connection

Overflow tanks and recovery systems --------------------

KLRC recommends you plumb the cooling system overflow as a coolant recovery system. This will keep air out of your engine which causes hot spots and causes variations in engine performance . As the engine cools it takes the expanded water back into the engine always insuring no air pockets and keeping you from overfilling the engine and letting it leak on the starting line because it is over full.

Weld Nipples 1 1/4" --------------------------------------------------------

These nipples have a rolled "barb" on the end to prevent the hose from slipping off.

These weld nipples can be used for fuel tank connections, water tank connections, or crankcase vent connections. Can be used with the 1/4 turn QD crank case vent fittings. Click here for more info on tank hardware.

Due to the design and jig construction of KLRC race cars we can supply CNC machined engine mounts and engine plates. If you have a KLRC car and want to change the engine type just call and order the new mounts and bolt your new engine in the chassis. If you are building a car order our engine mounts to build your new car to and then if you want to change later you can order different mounts. If you do not have a KLRC car and want to install a new engine in the chassis then make arrangements with us and we can custom mounts for your car.
