Here's Some Cylinder Head Porting Giving A 91bhp Increase In Power
Cylinder head porting is perhaps a lesser known form of tuning these days, but it can be an incredibly effective one. As we’ve detailed before, it’s all about smoothing and re-profiling parts of a cylinder head, removing any defects creating in the casting process while optimising and enlarging the inlet and outlet ports.
This gives an increase in the flow rate of fuel and air, leading to an increase in power. It can be done in your own garage with fairly simple tools, but you really need to know what you’re doing, or have a ‘disposable’ head to practice on.
If you do know what you’re doing, and are willing to put the time in, the results can be dramatic. The extensively ported cylinder head and inlet manifold combo seen in this latest episode of Engine Masters is seen giving the small block Mopar V8 its sat atop a massive, 91bhp increase in power. All for free.
Impressive…

Good to know. So you can get past the 1/4 hp per cubic inch without spending too much.
So that’s 1/4 times the amount of cubic, oh wait that’s still 0. I don’t have a car
will this work on a tesla ?
Yep, just get one of those laser things and point it at the batteries
Just ad some +5HP stickers
90? Bruh that’s more horsepower than my car makes
Same here. Only makes around 66 bhp on my car
42 hp and 630kg for my daihatsu, NA three-cylinder.
ZERO HP.
FIGHT ME NOW.
my bicycle makes 1 human power
That’s a whole VW lupo haha
To be fair, the cylinder head on a Lupo is probably much smoother surffaced and optimized than this.

Next month will be the benchmark for this being COMPLETELY done with the 350.
Wow, I knew it would make a difference, but not that big a difference. Must’ve been pretty crap from the factory
Agreed! The fact they got that much out makes me wonder about the quality of the heads. When u port a Honda b series head we only get 10-20 out.
197 bhp, to a possible 288? Jeez!
That’ll be one powerful Toyota if I did that.
Do it. It’s tedious…but so damn worth it.
Uh no… the gain is proportional to the engine displacement, boost, fuel ratio… and other various things, do that on your Toyota will probably get you about 15hp-20hp.
The old man reminds me of Clint Eastwood in gran tourino
So, this or 18 stickers?
