Lots of talk around about turbo upgrades and HP numbers. So I will go about my build. Built by ECC Canada and tuned by Slav.G. Mods are spool performance intercooler along with there LPFP&HPFP. Carrillo rods and pistons custom made. Modalworks hybrid turbos. Downpipes, ECU TCU Dyno tune running on e50. Car put down 612/560 WHP. Hot day and high DA will get better in the fall Not to bad. The 1/4 will improve as we are making adjustments to the tune. Car is shifting in auto at 6800 rpms and we are working on writing a tune to make the shifts point to 7100 and more boost out of the hole. We would like to run 10.3 10.4 on the street.
I'm sure the turbos from Modalworks gave you some added efficiency at higher boost pressure, but I ran out of fuel system long before I ran out of turbo.
I'm going to see how far the stock turbos and block can take me with a fully built fuel system first.
