Stinger, Just south of you in Bowling Green, we have a company called Quick Fuel Technologies. It is just down the street from Holley. Tyler Crockett uses them all the time. They put together some carbs for me for my blower motors that worked flawlessly. They test and calibate all their carbs on a motor. They are small and will make you happy. They are also cheaper that anything out there. Having said this, from 2nd hand knowledge you might need to contact Dean Nickerson. Carb set up in the box is a different animal, that someone with a lot of experience needs to handle. The carbs from him will be expensive, but most likely right, which means you might save a lot of time and money before all is said and done!

Talk to Nickerson (215) 781-1370. His personal boat engine has our Rtech Supercooler (intercooler and carb box in one) and a Vortech V-4 compressor. It's a 498 with GM iron heads and a solid roller cam, making 1013 HP @ 6100 RPM. Dean knows what you need.

thanks tomcat, we looked at the rtech system when getting the m3, but had to put our intercoolers in custom locations because the hatch was too short, and wanted to keep the sunpad. does anyone have a website for nickerson? thanks

Do whatever you have to do to get blown, that's what I say.

Just to clarify for other readers, the Rtech box is the same height as the Procharger carb box but it carries forward farther so you have to check the hatch clearance near the front of the engine, not just above the carb.

yeah, our problem was not just height, but it sticking forward...thanks for the link

The carb in the box setup never worked right.
