we went out saturday and tested the twin turbo tx20, started out at 23lbs of boost and it was turnin 7800 with 60psi of intake pump is tight tight, new ss amt aa-cut impellor in it, aggressor 9 vane bowl. at 15lbs of boost, its turnin 7500. so it looks like a aaa-cut or uncut hihelix is needed. you guys should feel how this thing leaves and pulls, its just sickkkkk just on 15lbs of boost, it pullls super hard
anybody have a chart to show 7800rpm on a amt aa cut? wonder were hp is at.
also need a oil cooler if anyone has 1, oil temp gets high after each pass.
