    Question 4-tec with 300 supercharger

    Just curious how many people are on here with this setup . Has it been reliable ? What impeller pitch are you running ? You using map tuner or something else ? Iím in the process of getting this setup built and Iím just curious if anyone else on here is still running this setup ? More curious on the tune and the impeller pitch and how much boost your making 🤷🏻. Just seeing if I can get any tips on a tune and dialing this setup in ? I really donít want to blow another motor lol

    I’m really just curious about people that have a 260 motor and put a 300 charger on it

    I've been running 300 charger with ET135 on my '12 PX for 3-4 seasons now. Not a single issue related to the conversion. Highly recommended for performance and reliability.

    Nice what are you doing as far as a tune ? I’m locked in the riva world and I just got the new data logger from maptune. Also I’m curious about your impeller and pitch . Also how many hours are you at on this setup ? I’m told I should be making mike 16.5lbs boost at 9100 .. that’s on the stock 300 wheel ,, for now lol. I’m also getting a block guard .

    You have a 300 charger on it ? I’m really thinking and hoping for that matter that this is a reliable fun setup .
