Its not making 1100 hp without the intercoolers.... Look at the proof tab where it shows dyno results.
Their 1100+ hp figures are on 100 oct fuel and intercooler since its taking 20 psi to do that.
91 oct non intercooled it only gets to 650-ish hp which is about right. Its only seeing 9 psi! 100 oct non intercooled can see 800 at about 14psi.
Assuming 75 deg air inlet temps, 50% humidity at atmospheric pressure, 9 psi is already at 174 deg F at 82.6% efficiency
Most turbos are no where near that high....something like 70-75 would be more realistic. 15psi at 80% eff is something like 233 deg F. its gettin hot quick

There was a buick guy who made more HP without an intercooler but was running 3 or 4 nozzles of alky to keep the temps down. I think he was running 20psi as well.

If its a custom designed wheel, for the boost range and motor requirements, I can see a high level of efficiency but I doubt its any higher than 80's % Even at that, you will have hot temps on higher boost levels. Alky is your friend if you dont have room for intercooler

that basic banks twin as been around for 15+ years...probably 20. Think 3rd Gens. Its a fantastic cast log that will never break...but because of the age, it was designed around a carb or TBI set up which would have an inherently cooler intake charge (fuel in the air charge vs. at the port). I have always wanted this kit with some 60mm in a 3rd gen with a CSU blow-through.
