ive changed my 500 cooler for a jap one just got to get it to fit ,ive just purchased the erl 2d water injection mf2 kit and will be fitting this too.so with the changes carried out it will be going to the rollers again when i bring her out.it was dyno'd at 396( cant remember if charge temps were on the print out)a month before i hibernated her so im hoping to see a slight increase with these cooling mods when its at the rollers for a set up in april.
