Hey guys, I am about to purchase a new converter from Chris but I would like to know what it is like to daily one of the looser converters. With my setup and nitrous I was recommended a 3C. Nitrous is only a possibility, I may leave it N/A. I was recommended for better N/A E.T to get a 5C. I am sure either way I will be getting a quality unit but I am afraid a 5C will suck to drive on the streets. Most commuting around here is highway and streets are usually not crowded. I dont want to leave performance on the table if I stay N/A and get a 3C so maybe I should meet in the middle and get a 4C?

This is a heads/cam car making 400rwhp and 370rwtq. The car has 3.70 rear gear and a 26" tire. Chris told me I should see around 2500-3000 RPMS to keep up with traffic with the 5C converter. I would assume the 4C would see around 2200 RPMs and a 3C around 2k, but I am speculating. Of course, I can always restall it. I have TD dumped exhaust so 3k RPMs draws attention. If I go with a 5C, would a BM 70264 Supercooler be enough or will I need something better? Maybe get a fan for it as well? I understand that higher stall speeds will be looser on the streets, I just dont want it to be unbearable. I am probably just worried about nothing.

Any insight would be appreciated, you dont have to run a circled to give me your opinions but I wont be convinced to go with someone else, Chris is my go to guy. Thanks!
