LV3 Chevy V6 Race Engine Dyno Testing

[@Cuhhmaromello]

That 4.3 is a bad ass little engine

[@Sdpartscenter]

The 6-1's sound awesome, but that's some excellent data. Making some solid power now! Thanks for sharing!

[@elirenigar9357]

4.3’s will always be bad ass no matter what model they are. Even the stock 20-teen era V6’s make great power! My brother has a 16 Silverado with a 4.3 and it is absolutely no slouch! Chevy knows they have to compete with fords ever-impressive ecoboost engines and I’d say they’ve done it! Especially in terms of reliability.

[@DoubleTrouble-580]

I built our 2014 over Christmas week and they're no slouch at all, I'm still in the process of finishing it but it's also a daily too

[@MrNeildrake]

Thank you. The distributor does create the need for external water pump. I’ll post a vid sometime on how I adapted it. The crank pulley is a stock one with damper cut off and machined down.

[@martintorres4566]

did you post a vid by any chance? very interested in seeing that distributor set up

[@C0rvette454]

Why couldn’t u run the ignition box like the carb ls with coils

[@MrNeildrake]

@@C0rvette454 That MSD box is only configured to run a V8. I've contacted the folks at MSD and they weren't willing to change it to run V6. On my other LV3, I run a standalone computer from Performance Electronics called a PE3-IG2 to fire stock coils. I run that with carb.

[@rascle29]

@@MrNeildrake where did you find the Coil Wires? Or just modify the OEM wiring, everything I’m finding online are for the v8’s, and I’m under the impression that the V8’s coil harness won’t work for the v6, it’ll cause misfires. Unless I’m wrong?

[@Tombstone_Actual]

That would be awesome recently got my hands on of these motors for free just needs a couple things wanna run it in a squarebody s10 i would love to see a video on the distributor setup as well

[@andrewfromphysics2921]

If you gain power because the oil is chemically less viscous, then it also stands to reason that the pump has an easier time pushing it through the engine. Less viscous friction losses through out the journal bearing surfaces, oil galleries, and pump itself would mean less back pressure and thus less measured oil pressure. **** assuming oil volume flow rate is the same ****

[@MrNeildrake]

Cam was timed to 110deg ICL. Lobe Separation was 115deg. Hope that answered your question.

[@torquetwisted4294]

I love this little thing... I think it's awesome with a lot of "outside" the box thinking. I really like your distributor setup and would love to build a similar setup for my aluminum 5.3 as I hate the MSD box with a passion and I am so over it failing. A couple of questions if you don't mind... 1] Where did you get the harmonic balancer that you are running ? 2] Any videos on you building the distributor setup ? I think this little ripper defiantly has some untapped potential. Looking forward to your adventure discovering it. Take care

[@billbaskin7904]

Could you please do a video on how you adapted a distributor to the engine. That would be very interesting.

[@TraysComedy]

You should build a boosted lv3 and try to get to that 1000 hp bench mark

[@kalebkloppe6193]

So, correct me if I’m wrong, but it looks like your header collector isn’t “clocked”. Meaning, the primaries don’t enter the collector sequentially, based on firing order. Track Day Classics pointed out that the firing order has a big impact on sound in their 8-1 header video.

[@MrNeildrake]

You are correct, I did not clock it sequential. I don’t think it would have helped the hp. I don’t know how much the sound would change. It’s an awful lot of work to go find out

[@syntropy3020]

Since 90 deg v8 it isnt even pulsing so I don't see any benefit of a 6 into 1 collector. Keeping the two headers separate with equal length runners will give even pulsing on each bank thus better scavaging for the desired rpm.

[@artjomslivenskis429]

I like the sound sooo much!!!

[@codyduncan6161]

So the question is. Where can I get one for my single cab Silverado??

[@lukemaxwell5375]

Awesome video, any more information about ls intake manifold swaps onto these v6s? 🇦🇺🇦🇺

[@copisetic1104]

The eldelbrock carb is more tunable. The equivalent of the holly If the friction was reduced in the engine to make an extra 2+ HP and Torque. I think the reduced friction in the oil system was flowing with reduced friction so the oil pump trying to pump oil thru out the engine oil pressure was reduced to the oil gauge.

[@middleclassthrash]

Those make more torque on e85 don't they?

[@artjomslivenskis429]

Which cars (platforms) LV3 can be easily swap into?

[@billballin6948]

Was the oil temperature the same before and after the oil additive? Hotter oil will make less pressure and more power.

[@nickperricelli4100]

I want to swap an LV1 or 3 into a Porsche 914. Where would I get the carb intake and what options would I have for a distributor? Or do they make a stand alone controller for coils like the kit for the LS?

[@veejay120793]

Did you ever put the engine in the scale?

[@Levisnteeshirt1]

Try Pro Blend oil treatment,,the engine will run cooler and make slightly more power

[@colinbowman8816]

That 6-1 had an interesting sound. Do you have some idea why it was lacking? Could be made to work better with a different primary dia or length? Would it work at a higher RPM?

[@MrNeildrake]

A few things hurt this header. The primary diameter was only 1 3/4” whereas my long tubes are 1 7/8”, there’s some pretty tight bends(and a lot of them) to get to the collector, some of the primaries are in excess of 40”, and then the inside of the collector where the merge is has a pretty low cross sectional area. In a rear or mid-engined car, like my Porsche 914, I’d give up some hp to keep that sound though.

[@colinbowman8816]

Interesting. I'm still confused about merge collector sorcery. Why doesn't an equal length, symmetric 3-1 on each side (making a 3-2-1 overall with the left and right systems being mirrored) get you a very similar sound to a 6-1? The exhaust pulses into the final tube would still all arrive equally one after another. Fabrication and fitment would have to be easier, and you could get shorter primaries, which helps move power to a higher RPM (do I have that right?) 300+ WHP from a torquey NA motor would make a 914 scoot for sure. It would outrun a lot of modern stuff on a track. kzbin.info/www/bejne/fneoeZWcr7ukq6ssi=C7RSJYHLOIG0V23Z @MrNeildrake

[@MrNeildrake]

I run 3-1 on each side then x-pipe on my El Camino hoping for similar effect but I think that last 2-1 needs to be closer to 3-1 to get that sound. In a front motor, rear drive car, that packaging is hard to achieve.

[@colinbowman8816]

kzbin.info/www/bejne/iaCoeZ15e5d3rpY Would you say this LS7 is making 'the sound'? Because it's 4-1 headers with a X pipe just a few inches beyond the end of the headers. It kind of sounds like a 8-1 as Mike points out. @@MrNeildrake

[@MrNeildrake]

@@colinbowman8816 I think so too

[@Mudlobsta]

What lobe centerline are you running?

[@ralexander9495]

Is this going into a vehicle?

[@solidfuze99]

What if the additive had something to do with thinning the oil a little which would allow the motor to Freer probably not last as long but what would give me the 2 horsepower and the speed pound of torque

[@MrNeildrake]

Yep, maybe. The stuff comes out of bottle pretty thick.

[@sergiodpk]

The oil additive didn’t make more power…you guys heated the oil temp that’s why it had less oil pressure and gained power…you say you guys cooled it back down to match the coolant temp as the previous pulls but the oil temp didn’t cool down…Hot oil + Cold Coolant = Max power

[@jamesmalloy9626]

100 psi plus oil pressure..? Lol

[@C0rvette454]

How much for an engine like this

[@matt81z28]

The numbers you're saying don't match up to the screen on the dyno pulls. Why??

[@matt81z28]

3rd pull matched up

[@MrNeildrake]

The final Dyno printout is averaging points for every 100 rpm. Display might momentarily flash lower or higher number.

[@matt81z28]

@@MrNeildrake ahh I see

[@jamesgoodman7603]

What year 4.3 will those heads work on

[@MrNeildrake]

2015 and up

[@Arrozconchopsticks]

I need that in my Jimmy

[@blkcoupequattro]

Little higher oil temps will often give more hp, that said not an entirely scientific setup, but unless the engine was broken in for 500-1000 miles your dealing with splitting hairs there, obviously you did some break-in on the dyno? How about running those same test on the exact min-sec startup and dyno run after sitting over night, an then pray in the morning the atmospheric pressure and air temp is the same as the previous day.....

[@MrNeildrake]

Engine had a few dozen Dyno pulls and break in prior to those. I think you’re right on the oil temp.

[@blkcoupequattro]

@@MrNeildrake engines sometimes with 50k miles and not broken in yet lol…

E85

[@TheRealTurboJesus]

Don’t know the exact number of thousands of dollars you spent to build this, but I have an idea, and I’d be utterly mortified if I spent that much on a motor that makes less power than a stock late model junkyard v8. Without boost this motor was an utter waste of time.

[@MrNeildrake]

Sometimes a v8 is just too big for some car swaps. This was a $500 core engine, $200 cam regrind. The heads were a development deal with FED and myself. Just a lot of my time, but I enjoy it. Thanks for watching

[@TheRealTurboJesus]

@@MrNeildrake I’m not aware of any scenario where you can’t make a v8 fit with a little fabrication.

[@OBSityproblems]

@@TheRealTurboJesus buddy of mine swapped an lm7 into a nissan hardbody and he had to alot of fabrication to the firewall in order to fit the 5.3 I think in this scenario the lv3 would be perfect shorter and 200lbs less makes same power

[@TheRealTurboJesus]

@@OBSityproblems whuuut lol put a smaller weaker motor that sounds like ass in cause you don’t wanna do more fab? Sounds super lame…
