    Talking External Intercooler increases

    I have a full stage 1 with a custom air intake turning [email protected] all day(73.1 best on the buzzer).I have a xs intercooler with all the plumming.How much of a performance can I expect for just adding an external intercooler(top end) ? I am also thinking about a 15\20R. So my question is it realistic to expect a 2-3 mph increase from just the intercooler or do I need a 15\20R to get their?

    i think you will need a sc wheel to turn a 15 20 go green on that..if you can wait save and go with the s3 charger and 42 injectors you wont b dissapointed... i am understanding the intercooler not only cools better,,, but flows better... as well ..so, you see more boost pressure..most skis w wheel and intercooler are 75 ish i thinks 3 wheel add up 2 5 more
