OK lightning bros.sis i have some serious questions which everyone can have a say this can benifit us all. with out going inside of engine adding all of the mods on outside of engine you want. how much horsepower can be produced by adding these mods. now this does not enclude changing injectors but you can change plugs valve bodys.

 

I'd say with just bolt ons around 450hp.

 

how long does the engine have to last?

I'm running about 475HP at the flywheel on my daily driver (stock blower).

later,
chris

 

442 rwhp with bolt-ons
But...........

should be a little more after the next bolt on

 

428 RWHP with a 2lb pulley....and a couyple other things, but all bolt on.
