07 rxt need advice on charger
Hi guys i have a factory rxt and i want to do some mods to it
i have the following parts brand new at home ready to install
fizzle xs intercooler
42 injector (might need to go higher)
rear rive exhaust
opas block off
new wear ring
i still need to get a super charger and maybe a stage 1 for the grate, wedge and intake and i can tell the seller to change the st1 prop for what ever one i need.
I was thinking about buying a x charger and i feel that basically what i am doing is making my rxt a rxt-x, i don't want that, i want to be faster so i am thinking about a 2rude or 3rude my question is i don't want to change ecu i want to keep my factory ecu and i want to know if i have to do the valve train upgrade for this chargers, also do u guys recommend this chargers and what speed should i see. Hopefully you guys can estimate my tops speed with this mods.

In FL heat w/stock ECU
X-charger, 42s, RRFPR, 15/20R 75-76mph
X charger is right around $700
Upgrade the x-charger "mini rude" $698 & will need 50s now and 15/22R Guessing 78-79mph.
2rude, 48s or 50s, RRFPR 15/22R 78-79mph
Have you current rear housing machined $100, SC bearings $100, metal washers $100 & 2 rude upgrade $675 This is what I did.

ET 68-140 all you would need is 50# and rrfpr and have your prop pitch from speedfreeks and a/f guage. You should be good 78/79 mph, plus this is a hell of a deal on et 140
