not sure on the boost needed but with the camms i am sure it will not max out the blower even with stock heads

as far as the fuel goes in the long run i am going for the cobra tank and pumps but i want to see how far the bap and svt can take me before i need more fuel

i am going for reliability over performance as this car is my daily driver so i dont want to push anything to its limit and keep it there

example if svt and bap max out at say 510rwhp then i will dail power back to say 460rwhp until i get the tank and pumps

Yeah the blower will be fine till 600whp or so. What MAF are you going to be running? A lightning maf will peg before 500whp usually, so that's another couple bucks to think about for an SCT maf.
 
That will be a hell of a sleeper. 500RWHP out of a 2V GT car. Nobody will expect that! They pull really hard with big boost. I rode in a 10.30-10.50 car. 1996 Mustang GT conv with a 4R70W and 15-16psi...WOW!!
 
the S trim isn't big enough to do it with the restrictive stock PI heads and cams.

Tim has made 600RWHP with the stock heads, but using his cams. Ofcourse it had a built block. (Im pretty sure it was an S trim....but i could be wrong)

Im pretty sure just a set of cams and boltons, along with a small pulley would get you to 500. Stock bottom end should last a while as well.
 
With a 5spd you could get 500rwhp with an S-Trim

My car made 430rwhp on a Mustangdyno and only revving the car out to 5500rpms and I normally rev to 6750. This was through a messed up auto that was definitely sucking power. That would be about 460-470rwhp on a dynojet, I’m sure it would have made an extra 30rwhp if I would have revved it out all the way and if the tranny was up to par.

This was with the mods in my sig except for the T-Trim.


I'll have new numbers within the next two weeks, weather permitting, with my T-Trim and new auto.
 
Yeah, the nice thing about 4.6's are the strong blocks too! I am amazed at what these cars do with boost, lol.

edit: This also makes me wonder why you would need a stronger block. :shrug:

The blocks themselves may be tough as nails, but the internals inside them are about as rigid as tinker toys. A new block alone is only worth about $200-$300, so most companies sell them complete and assembled with the needed forged components to save you the hassle of having to put it together yourself.
