After to many conversations to remember with various board members including Rich from the GT Team, and then finally Jack at Muscle Motors I decided that a pulley swap is in order for my gal too; the only twist is that I decided to have it pre-installed on the new 3.3 Whipple Super Charger.
Initially I openly shared that I likely would not install a smaller pulley however based on my experience with many a supercharged gal (cost no object mind you) I remain convinced that the larger super charger will allow for lower discharge temperatures that will in itself afford a much stronger and longer power curve not to mention the numerous design benefits of the Whipple as well.
There is no doubt that all FI gal’s respond best when the air is crisp however the performance will fall off significantly during the heat of a summer day. This was one of the reasons that (for me) the idea of a smaller pulley was not a draw card because I know that within the design of the OEM 2.3 supercharger the results would be measurable increase in discharge temperature. Now let me be clear; I remain convinced that the smaller pulleys that are being installed are likely the single greatest performance “BANG” for the buck this is why I qualified my comments with the statement; “cost no object”. To a gal I am certain that an increased power curve and resulting HP number is successfully experienced by “ALL” that have the smaller pulley installed. Now add to this there in “NO” doubt in my mind that the heart and supporting drive-train components of these gals can comfortably be pushed into the 7-800 horsepower range with little or no concern.
So; to summarize; I feel that the ideal situation would be cooler air at the inlet (the radiant heat developed as the result of the OEM muffler is phenomenal) which was addressed on my gal by replacing it with the AccuFab exhaust that I completely wrapped with the Thermo-Tech product. It is as the result of this that the IAT (intake air temperature) remains much lower and therefore the IAT sensor itself that communicates with the PCM will likely not respond by pulling timing/power. Now add to this being able to reduce the super charger’s discharge temperature will afford the gal’s heart to produce a measurable increase in power (even at the same boost levels) however as the result of the 3.3 Whipple super charger’s design an increase in boost can also be achieved while still reducing the discharge temperatures.
I expect that with the combination of these pieces the operation of the gal will remain well within the design constraints of the OEM heart and she will be very happy and endure a long relatively painless life hovering in the 700 plus RWHP range.
Once again Jack at Muscle Motor’s was a pleasure to work with.
All the best
