Throttle body spacers
« on: February 13, 2011, 12:03:12 AM »
Neither Hesco or Poweraid specifically mention GCs ....Yet do state I6 engines and they do work coz Ive got one on me TJ...

Is it cos the GCs are configured for more power?

the vortex twists the wrong way on  a gc so you would have to get the correct vortex spacer from the states

I may be wrong here but my understanding of them is that they reduce what is called as fuel stand off, the theory being that when an engine  is running there is a point  at which the fuel air mixture has no where to go as all the inlet valves are closed but there is still some residual mixture in the manifold ,so when the next firing sequence begins the fresh fuel squirted in  to manifold  and forces this back past the throttle body . By steping the throttle body away from the manifold it reduces the amount of fuel that does this and hence inproves throttle response and smoother tickover,well thats the theory anyway. I have seen a carbed engine where you could place your hand above the mouth of the carb and get petrol vapour settle on the palm, so that does happen.

longer intakes generally move power & torque up the rev range, not something you want offroad, and pulse tuning of an intake is an exact science, not just a case of sticking a lump of ally in as a spacer.

I have had one, took it off, it moved the shift point on my 4l auto xj, went from going into top at 40 to 50mph, bloody irratating. Anyone got a link to a before & after dyno run?

Any 4.0 engine from the same year will use the same TB spacer TJ/XJ/ZJ (at least the years in question, late 90s).

I have one on mine, it changes the throttle response a bit but if I'd be annoyed if it had cost me a lot - I think it worked out to be about £26 when I added it onto a big Quadratec order and the exchange rate was ~2 to 1 (those were the days  :icon_sad:)
