PULSE COMMAND TM
- SPACER -

U.S. PATENT NO. 6,595,175
MADE IN THE USA

Tooltech Systems is proud and excited to introduce our fully C.N.C. machined "Pulse Command" carburetor spacer. A design so unique, it has been granted a U.S. Patent.

As we all know, balancing the plenum to create harmony among the power enhancing components of an engine has always been a difficult task. With our advanced concept of protruding below the intake manifold mounting surface, as well as the blended scalloping above it, we offer bolt on horse power.

In dyno testing, gains of 15 to 25 H.P. are common place with highs reaching as much as 35 H.P. The power band has also been stretched to start at a lower R.P.M. and peak at a higher R.P.M.

The fact that we first developed this spacer in the early 1980's has afforded us many years of feedback from the racers themselves and has led us to the following conclusions:
     In drag racing: Quicker E.T.'s and higher M.P.H.
     In round track: Faster qualifying speeds, more power off the corner and overall better drivability.
     In boats: Quicker planing and more top end.

Note: Discounts are available for purchases of 10 or   
more of any spacers. Please call for more information.
