we got the Exergy 10mm pump in today , its exactly what this turbo setup needed , low boost fueling substantially improved spoolup , and up top it gets it much harder. i haven't tested it with too much fuel yet, but just testing the tyrant 1900us file , it was night and day from the stock pump. we made 579 with the stock pump ( prolly 620-630 on stock tires) , it will be interesting to see what we can do now. prolly end up with a hole in the block, guess we will start pushing the 17' to see what it will handle .
Good to hear that a pump and turbos can make a nice result. I am hoping the new rods can handle more than this. Looking forward to the dyno numbers.
