Remove all the internal fins inside the intercooler and it will significantly improve flow, but also decrease efficiency. There would be no way to see that mod with out a borescope. With the right fuel, the intercooler wouldn't be needed. OR.......use the throttle body coolant passage to spray methanol. EDM a bunch of holes through out the throttlebody to look like porosities in the casting. Block the heater tube inlet and outlet, and run the alky pump and tank in the heater box. Add a bit of green food coloring to the alcohol, and wha-la.....it is just anti-freeze (or red for water-wetter) if they tear you down. I considered running in NHRA stock eliminator back in 2000 or so, and had the alky system scienced out pretty well. Sure, it'd be cheatin', but like they say....."Those that don't cheat in Stock Eliminator.......Don't qualify!"Lots of ways to skin a cat. Gapped gaskets between the inlet bell, lightweight parts EVERYWHERE, then add ballast, leaking inlet hose (pin holes through-out) soak tires in VHT, But still VERY hard to compete with 565+cid big blocks.
