I know a 10.5 racer that used all three types of power adders including twin 88 MM turbo. Intercooling using race gas is mandatory to keep the motor out of detonation. He chose a water to air intercooler (it was twice as big as all the other racers in his class, he won that series every year he raced in it including when he used a Pro Charger ) with ice in it and he said to use the biggest one you can
That was a real high $$$ maintenance motor though, short parts life
