It was simple to bypass. Simply disconnect the pipe from the rear exhaust manifold and block off the manifold with a plate. Then add a small filter to the open pipe so the EGR is only pumping in fresh cool air. That worked for me for a couple of years.
Now I have the PCM code removed so I now have the entire EGR system removed.
(one of the tricks that keeps me ahead of the pack in the competition
even though Bill will never admit it )
That 15 F is a big difference. I have run all my cars for the last 30 years with 160 F stats.
Everything lasts longer....hoses, oil, gaskets, ...
It'* just enough to allow the use of one size smaller SC pulley. That'* good for 10 hp.
By itself, it does not improve performance but it raises the potential for making more power.
The old rule holds. 1% more hp for every 10 F drop in air temp.
