Can I get 500 hp NA out of my 03 GT? If so what would I need to do? I assume a 5.1 Stroker would be the start. It has to run on 91 octane by the way.
00s281sc368 said:500HP N/A means 110HP/liter...
Smaller blocs like the M3 or S2000 get that, but that's also with a 8000rpm or 9000rpm red line... higher compression and 4V/cyl of course...
I get the same 110HP/liter at only 6000rpm with my stock 4.6 2V block and the help of little boost not to mention the higher torque all the time!
Just stick with you plan B and get boost !
ponysarepretty said:A curious thing is if your power were to peak at 6000 RPM and the Honda were to peak at 9000 RPM, you would have to make 50% force (ie torque) to have the same amout of power as at 9000 RPM.
At 10500 RPM, if you had a 300 lb/ft motor, it would be making 600 hp there

like everyone said it would take alot of cash to do that if it is possible

just wanted to pass along toms knowledge that was handed down to me.
EDIT: on a side note... you do realise that the cost of this is just slighly more then the KB... you get the power, AND a built block though.... VTs recommendation on this block was the spray the hell out of it (their exact words) to get whatever more power you wanted..... NOS direct port anyone?
