16 psi......








For about 10 minutes [xx(]

 

lol 16 psi horse power waterboy ? I have heard tales of SPI's turning around 125 to 150 HP at the crank thats about all I have seen.

 

hmm alright..... but damn 16 psi is not badis that even with allthe bolt-ons?

 

I heard the max is about 225-250whp would be the max with stock internals. But I would stay under 250 if you don't have custom pistons and rods.

 

how do you get that much horse power[???] [???]

 

their is only 2 ways my brother and that would be an all out race engine or a Turbo which is your best bet. But its going to have to be all custom. Their are no turbo kits out for the spi. And it need to be tuned properly or even at 200hp you can blow the engine.
