In my last post, I gave the results of my first dyno test (395 rwhp/412 tq on a mustang dyno). I'm not satisfied with them (go figure...) , and am looking toward future mods. I would like to drop a 100-shot spray into the picture, as well as have Stiegemeyer's port and polish the s/c and plenum. Long tubes and straight pipes are also in the near future. Now, my question is this - with these mods added into the picture, I am assuming that I will also need to go into getting new rods, pistons, crankshafts, etc...Am I right, or could I get away with not going that far (or just adding the rods)? Internals such as these are completely foreign to me, and I would like as much advice as possible.... Will I need Walboro 255's and some 60cc injectors too?

Any help is appreciated.

 

395 HP on a mustang is great but the torque seems low.
Not sure of your mods so it is hard to figure.

 

Right now, I have the following:

6# lower, CAI, SBTB, FTVB, Bassani catback, idler pulley kit/bracket, Predator tune.

Looking to add the 100-shot, long tubes/straight pipes, ported eaton and plenum into it...

 

If you go with anything more other than long tubes or ported heads or cams you are going to need a forged bottom end!! Thats my opinion! you're building alot of pressure and need to help that motor breathe! how about dropping down to a 4# and port the blower!

 

the nitrous and port is a good idea on the stock motor but start with a 50 and see what that does for you.
