MY 500rwhp NA 2v
4.6L block 2v NA. This is on a mustang dyno so trying to find a dynojet which seems to be the numbers everybody likes to go by. Should be about 525rwhp on a dynojet.
Watch the video to the end, numbers are at the end.

F***ing amazing. I thought they said it couldn't be done? There was a thread here (lifted from somewhere else, iirc) a year or two ago of a guy who made almost 400 with an n/a 2V but he had to have around $8K or more into it - think he had a 5.0 Aluminator block and everything necessary inside of it, TF heads n' cams, high compression (11.5 or maybe 12ish), which while cool is def not cost effective power.

I'll take it to the track when it opens for the season up here.
I have about $6000 in parts for this build which is less than what it cost to supercharge and build the block to handle 500hp. But to be fair I do all my own work from machining to tuning so the cost for me is lower.

Very simple engine build
Stock bore, 3.75 stroke, 12.5:1 CR
ported 38cc TFS heads
Custom grind cams (top secret)
Ported edelbrock intake, 6061 plenum, 75mm TB
1 3/4" ARH longtubes
90mm maf (almost pegged)
42lbs injectors (had to raise rail pressure to 50 psi due to reaching max duty cycle)
A/C deleted, electric water pump, deleted power brakes but kept power steering
The key to the power are block prep, balancing and the cams. When I machined the block I made every cylinder and exact copy of each other. Had to send a few pistons back to manley because they were not within my specs and they sent me the correct ones. Same with the heads I ported them to all flow the exact same numbers and made sure each chamber cc the exact same. You would be surprised how much high dollar parts are off. When I balanced the rotating assembly I weight matched every piston and every rod and then balanced to within .002 grams. I designed these cams to work perfectly with this engine. I won't let any specs out but if you know anything about cam design and function I'll give you a clue. The engine is 12.5:1 CR, has 32 degrees of timing at 7000rpm and runs on 93 pump gas.
Most people say 500rwhp is not possible with a 2v because they buy off the shelf parts, throw it together and make crap power.
I was very meticulous when I built this engine and I had the car strapped to the dyno for almost a month making sure the tune was exactly perfect. Luckily I have pretty much unlimited access to a dyno.
