SBE JUNKYARD TURBO 4.6L vs 4.8L LS (FORD VS CHEVY)

TWIN TURBO MOD FORD VS LS, CHEVY VS FORD, 4.6L VS 4.8L, 19PSI! WHO MAKES MORE POWER, A MOD FORD OR LS? CHECK OUT THIS VIDEO WERE WE COMPARE A MODIFIED 4.6L 2V TO A MODIFIED 4.6L 4V TO A MODIFIED 4.8L LS.

In the 80s, we thought the manufacturers were going to kill the V8. Now, a smallish displacement V8 can hit 1,000hp with off the shelf parts relatively easily! It's a good time for engine performance!

[@midnight347]

The 2v does fine for a 281 cube motor from the 90s. It makes as much or more power than the old 302 h.o. and torque stock or modified and when it comes to modified forged internals vs forged internals the mod motors can make way more with stock block than the old 302. Idk why people think the 2v sucks it's just as good as the 302 in every way and for big power builds it can get there easier and cheaper than the 302.

It’s a tuff one to figure which one makes the best gains. On one hand Chevy got that beautiful hp and tq curve that wins races and would eat Ford 4.6 na all day but then when boost is added the 4.6 benefits from the extra rpm even though the curves are not smooth through out. Also it had an air to water vs air to air in a stationary spot so might have better gains from the air to water on a dyno. In either case they are great good video man.

I've seen 500rwhp from stock SC'd PI 2v mustangs. Risky because the weak pistons and rods but impressive nonetheless. Been in a new (at the time) terminator Cobra with a blowzilla w/ 667 rwhp (again engine totally stock), owner blew the tranny at 11k then the engine at 16k. He never fixed it, sold the car as is with 16k miles (he was the owner of a mustang shop also). The power was literally tearing the car apart, the interior trim pieces were falling out of place, everything in and on it rattled and shook under acceleration. This is why I always modified the "big" cars instead (Mark 7, Mark 8, Thunderbird, Cougar).

[@midnight347]

I've never heard of people's terminators falling apart from 667 rwhp nor have I seen too many terminator engines going at that power level at that low of miles it sounds like your friend and/or his tuner didn't do the car any favors. They're pretty good cars and they can live easily past 800 wheel many have done it.

I'd be interesting to see you put prices on each of the engine upgrades/modifications both Ford and GM and corresponding HP/TQ levels, what peoples responses would be. #nobrainer

[@midnight347]

It always comes down to cost. That is always ls guys arguments and the 4.8 prob does cost less than a 4v 4.6 theyre alot more common its to be expected but if you have a mustang there is alot involved in swapping an ls that wouldn't be necessary keeping the mod motor so that in and of itself offsets alot of the cost. Ls are great engines but I cannot stand them to be swapped into mustangs especially mustangs that had a badass engine to start with (like the 4v 4.6). No reason to swap anything. As far as the cost to do the mods the only thing that is going to be significantly higher is cams because there is 4 and not just 1. Outside of that cost isn't as far apart as what you'd think. The ls has been literally beat to death God I am so sick of them. I wouldn't swap one into my mustang if it was given to me. I'd find an s10 for it to go in.

The 2v can make power. It just takes a bit more boost. 1100 wheel hp is definitely doable. I have even seen 1000 hp on stock ported heads. It's definitely the harder way but it can compete. My little 2v isn't very impressive at mid 500 wheel hp but that's not the motors fault. That's because I need to build my trans before I add more boost

The coyote smoked the 4.8 or 5.3 it took the 6 liter to Match or exceed the power output of the gen 1 coyote and it had full aftermarket heads cam intake where the gen 1 coyote had a boss manifold, ported stock heads and cams. This was a gen 1 coyote when they first came out he tested. It's pretty obvious the 5 liter owns especially when boost enters the equation lol. The old 4v was badass and the coyote is just a newer iteration of the same thing with more displacement, rpm, compression, headflow and tech. It is an animal.
