Ported Heads Before & After (measurements + dyno)

I finally received my stage 3 ported cylinder heads from Livernois and in this video we go over: what is porting, why it makes a difference, and what kind of power gains we can expect.

[@denniss4951]

could always build the engine and put a blower on it. I think you can get somewhere around 630 horsepower or so if you do it right. I want to do it some day but my father doesn't think it is a good idea. There's been a lot of 3V back in 2005-2006 I can remember with superchargers putting out over 400hp.. it's been doable for quite a long time. And yes, I can afford ~$16,500 upgrades to the engine.

[@wiselinkmarque3947]

Mine doesn't perform like an 'underdog' and it is still stock. People seem to be spoiled with what is available today and forget how much power you really just need on the street. Not everyone lives on a race track or a 1/4 mile drag strip. At least, I don't and I never will. Also there were already Chevrolet LS V8 powered cars way before the S197 GT came out in 2005 that would outrun it.

[@loganweisz8948]

wiselink marque yea all the new production cars coming out have an insane amount of HP especially for daily driving.

You’re one of the few people keeping the 3V alive. I’ve been contemplating on saving for dob kit trying to keep it around 500whp for a Decent daily.

Dayyyyum dude! Very cool to see this route instead of the typical FI power adder

[@gforce_117]

Edit: I got porting done. All done by hand by someone with many years experience. They did it per my application. Gains we’re 25% average on intake across valve lift range and 48% average on exhaust. Actual cfm gains at .600 were 212 up to 268 intake, 145 up to 212 on exhaust! So it performs between a LS1 and coyote head. Great flow for 4.6L. OP: Building one of these too, talking about porting with engine builder right now. Turbo application. Crazy part is the gains N/A are multiplied under boost. Let's say you gained 75HP N/A, thats worth 150HP at 15psi! Insane!

[@michax175]

If you port head doesnt it mean that you will lose more velocity? Remember when you deleted butterfly valves. If I m right that means you will lose even more low end torque. And putting turbos on top of that instead of somethink that will give you low end torque like supercharger... idk man. My guess is that you will have loads of power at top of the rev range but low end is gonna suck. *Correct if I m wrong* PS. Love the build either way. Keep up the good work.

[@Beep00p]

Extra displacement will add some more bottom end

[@michax175]

@@Beep00p Yeah you are right but how much? you said "some" but will it be enough for money that he spends.

[@Beep00p]

Here's a link to an old article with some dyno numbers comparing stockish 4.6 3v and these stage 3 heads with comp stage 4 cams. Peak torque was higher in the powerband, but their numbers show more torque everywhere. www.mustangandfords.com/how-to/engine/mmfp-0812-livernois-motorsports-cylinder-head-upgrade

[@michax175]

@@Beep00p Thanks!

[@Beep00p]

In theory what you're saying about flow and velocity is correct. There can be shifts in the powerband. However, there may also be overall gains from increasing the efficiency of the engine. The heads do have higher cfm ratings and larger ports after being reworked, but that doesn't mean they'll lose bottom end (though some can.) There may have been something in the passageways that was technically adding velocity, but overall impeding the combustion process. The initial head architecture and porting work makes a real difference. For example, if someone just takes some heads and opens them up as big as possible they could lose power everywhere, yet only minor port work may result in bigger gains. Blah, blah, blah. Other supporting mods and tuning will also effect the end results and can change them one way or the other significantly, so lots of variables and can't say for certain how this exact combination will work out for him. Just my few cents, who knows! 🤷‍♂️ I'm excited to see the results myself

[@paladain55]

Wouldn't trust the Livernois numbers. They are bad about lying about inflated HP numbers to sell parts. A stock 3v Makes 350bhp on the engine dyno with headers and bare minimum accessory drive. Heads will normally add 30bhp on the engine dyno. Convert to rwhp I say stage 3 heads on your setup will add 25 whp. I say this not to be a dick. Looking forward to seeing the results. It will be hard to decipher the hp gain on these as you will be adding these to a motor with boost as well a drop in CR. The drop in CR will reduce hp by about 10-15 by itself (NA), but won't matter as you will be making too much horsepower when you boost it. Thanks for putting out the great content man! Make sure you get boost cams in the future. NA cams in a boost motor will make less hp than the stock cams under boost conditions.

[@JETZcorp]

There is little difference between rough and polished intake ports in terms of max flow. But!! At lower flow rates, such as low-mid RPM or when the valves are just barely off their seats, rough ports have a MUCH better aurflow velocity. The rough texture creates a large boundary layer of still air which progressively collapses as airflow becomes greater. This effectively acts like small ports at low flow regimes, and big ports for high flow. The best of both worlds. The grooves left by a CNC machine are close to ideal, which is why the dark art of manually adding grooves to intake ports has disappeared. That used to be a thing, albeit relatively obscure.

Springs, shocks, anti-roll (sway) bars, Watts link in the sear suspension, better sway bar end links, higher quality front control arms, and like your GT a 1 piece driveshaft.
