Seems like there is quite a bit of conflicting opinions here ! first this top tuner Joe, 10 second street FG xr6 and guna unleash a 9 second monster! Last few days I talked to a few, who I think are top tuners , well they go round the world tuning race cars, and most of them actually own four bangers that do low 8s and 7s and incidentally I recall seeing Plazmaman at WSID with there own 2L turbo doing low 9s and that was 8 years ago! I asked one of these tuners which cooler would be best for my 2010 FG and mentioned that there is a PW guy saying his coolers are so much better! he looked at me and laughed! He said its all in the tune and that Plazmamans new tube and fin coolers work really well he has a 600 x 300 on a race car with 420 kw he also said if you think bar and plate is better Plazmaman sell them so now the technical stuff he mentioned to the dummies like me on bar and plate coolers measure the tube thickness the distance between the tubes and count the number of fins in one inch inside and outside and if they are the same its the same core! that is if they both have the same outside dimensions, he said there is not teck to a Chinese core! unlike the American and European cores that is why no race teams use them! I did some research and Plazmaman bare and plates are much cheaper than PW Hmmmm interesting I looked at this forum to get information and ppls options so when I make my purchase it is the right one for me, more investigation coming !
