Impeller recommendation / Expected speed
Currently my stock 08 GTX LTD will run 66mph.
Soon im going to be installing an xcharger, injectors, 4 inch air and impeller to suit.
What speed should i get from this? will i break 70?
Also which pitch prop would be a good start?
Plans further down the track include intercooler upgrade, retainers and an ecu reflash.

Assuming you've done the other hull/handling freebies...the set up you're thinkin about with a 15/20 should put you at or near 74.

What freebies would they be? grinding the rear of the intake grate level and plugging ride plate holes?

Do the intercooler when u do the charger and inj......u will pass 70 right up. 15/20r

I wanted to avoid doing the intercooler at the same time as the charger because id prefer to spread the cost out.
If i go intercooler it also need: exhaust (either free flow pipe or rear air + opas block offs), rrfpr or ecu reflash (which would mean doing retainers) etc
