@@Z-e-r-0 yeah but its strangely relaxing listening to them talk about the stuff, I grew up in a family owned speed shop before i started school, maybe thats why lolz
This was my favorite episode. The sheer joy that Frieburger showed when Brulee didn't flinch when he asked if he had more nitrous! Man I miss when you guys showed engine masters every two weeks. I looked forward to it. Then u went to subscription only. You guys have taught me so much. Thank you!
I respect a full episode every now and then. Thank you for releasing a fully. I understand nothing ain’t free nowadays but episode’s like this ill stay around. 😂
That was a joy to watch. So nice to see the genuine enthusiasm and pride as that monster cranked out both of 1500hp. Great video guys and congratulations!
A true testament to that motors assembly and parts. Throwing all of that at it and it kept taking it is unreal. Go 12:71 and 1700 HP is yours for the taking. Bravo Boyz!
There are no words for how grateful I am for the return to youtube. It stared back in the 70s reading Smokey and now continues. Ya'll have no idea the engine I'm going to build for my wife's Explorer. Actually she has no idea 😂
fast and furious tunes, gone in 60 seconds background jams, dyno guy looks like robert duvall....all while running a supercharged, nitrous fed big block. this is awesome!
I'v missed this show. Hopefully this is a sign they are coming back to TH-cam because unfortunately for them I havnt missed them enough to sign up to motortrend subscription 🤣🤣
I hope there's an engine masters revival with Brule retired it won't be the same. But this is the best show I can find, I just keep watching it over and over again
Boost level is also a measure of restriction, like said in this vid. If you do head work and increase flow efficiency, you can actually make markedly more power at lower boost level. It feels a little counterintuitive on it's face, but if you think about it further, it's really just common sense.
You guys are all miles ahead me in engine technology but I really enjoy seeing the results from the dyno testing. I don’t even come close to understanding all of the elements that go into making more power in an engine. Great series.👍👍🇨🇦
Awesome! Boost is one thing, and I think Gale Banks explains that pretty good. For this test, increasing the overdrive ratio of the roots blower, I think we see a twofold effect: 1) Increased temperature, so less dense air. 2) Severely increased parasitic loss just from driving the blower. Would have been interesting to see nitrous on e85 with the "happy hour" pulley setup. Roots is good for response, but for big power there are better boost techniques available. You have to decide what you want.
Yes I think people have forgotten what these superchargers were originally designed for and how long they have been around there is more efficient and improved designs on the market now maybe not so cool looking though 😎
I wish I could triple like this. You could pick up 20 HP if you polish the blower. I have the same NOS setup on my 6-71 blown Chevy I6 292. Thank you for your time.
I just seen a Hertz commercial watching your video and it reminds me back in the 60s and the seventies when the kids would go rent a Hertz car and go pull the hemi out of it and put something else in there and take it back and they wouldn't figure it out for months
Is this the best episode of anything on motor trend ? I think it is ❤️ What i would like to see is 10-14-/71 blowers compare to what you had right now.. blowershop makes those as well 😇
David. Do you bring the rpms up slowly to 1800 to see what the air fuel ratio is on gasoline to know what size the idle feed restrictions are. Then take it to 4000 rpms so you see what the primary jets need to be. Then during a power run. To see if it goes rich or lean as the secondaries open along with the primaries
This is also why I added a 75 HP dry shot on my 2004 Acura TL with intake, headers, exhaust, six speed manual swap. They make 270 HP stock with a 11:1 compression ratio.
Methanol is your friend! combined that with 14-71!! take a look at air temps after the 350 shot. that shows you how much N20 it takes to cool down the air temps. good stuff!
I'd say that whole deal there could be done for right around 25k! Just the blower setup alone with belt & pulleys is probably around 6-7k! Then the engine itself with the block, head's, forged guts, prolly around 15k! But you could save some here and there if you could find some used goodies. To go fast costs a lot of money!
The 8-71 is really only designed to feed 568 cubic inches at 3 psi. Therefore you’re eventually going to run into total flow limitations no matter how fast you spin the pulleys. The housing will only flow so much air overall and when you spin the rotors faster than the housing will flow, they just fight against the air. That fight is friction, friction is heat.
It's not changing temp because you are reading peak temp. You run up to 5k before you hit the switch. Temp drops after that, but you won't see it if you are only looking at peak.
Bigger blower = less overdrive = lower air temps = more power. This engine needed a 10-71 from the start. That's the minimum for anything over 540 cubic inches. It also takes more power to spin a blower quicker and that comes right off of the crank.
One idea for a show I have had is taking 3 motors; 1) very mild 100-200 hp, 2) 400-500 hp, 3) 1000-1500 hp - then dyno-ing them on the engine stand then in as similar cars as possible to demonstrate powertrain parasitic losses.
So, I heard one of the guys mention roots-style blowers are prone to building up heat. Are centrifugal blowers less susceptible to producing heat? It's my understanding that all forced induction systems will produce heat to varying degrees, which is why you should introduce a charged air cooling system, correct? Also, this was an impressive test in that my takeaway is: the NA motor made approx. 750hp, and the blown, nitrous, E85 setup doubled the hp.
I don’t have much experience with boosted applications but from what i under stand with a centrifugal blower you can run an air to air intercooler or some other cooler much easier than a roots style
Centrifugal blowers are more efficient and heat the air less. There is also less mass, along with usually not being mounted in the valley, so there's less heat soak with them. However centrifugal blowers don't make the boost and power at low rpm that a positive displacement blower will. At the end of the day there's pros and cons to all the different styles of forced induction. Just have to figure out what matches to the idea of what you want.
I wonder if they were running up against the blower's efficiency curve here. I.e. adding more pulley just wound up making the blower's power consumption go up enough to wipe out most of the gains. Which also raises an interesting topic: how would this play out at high altitude, e.g. on a Pikes Peak car?
I wonder if you had backed it down to 9PSI on the blower if it would have still made similar power with the 350 shot of NOS, due to even colder air temps. Either way, awesome set up. When you said Finnegan uses the same blower, did you mean brand or brand and size (8-71 vs 10-71)? I felt like Finnegan never revealed how much power the Blasphemi made.
man I had forgotten how much I loved this show, used to watch it a lot.
you have never watched this show lol its the same things every single season just in different context. watch season 1 and you have watched them all.

It used to be dope
We need more full engine masters full episodes here pleasee
never going to happen. spend $5 a month on motortrend
Im not in the US...
Yeah not in us can't even use a VPN because they want a us based address and banking

That moment, I can only describe as Too cute😂❤
I love the full episodes!
Boys , remember to like and comment on these videos ! It’s shows the value we see in this stuff and hopefully they’ll keep it coming !
No. Trash motor trend for taking this content away from us. Just like roadkill.
Love how they all got so excited it was like kids on Christmas! Keep the full episodes coming motor trend!
Hmmm.... losing a bit of power... but having flames come out of the exhaust pipe... seems like a fair trade.
The recklessness was absolutely awesome.
how much money for that assembly = $45,000 = i would never want one - just a race motor !
Please, don't stop doing these events. The three of you are great.
I love all your Engine Masters shows, but i'm thinkin' this one is my favorite !
I was waiting for Freiburger to pull a "Finnegan" and say "best day at work, ever". Good job guys.
Seriously love these guys. They and Powernation are the last of a dying breed of real gear heads.
I noticed the manifold temp dropped to 138 degrees F with the 350 hp of NOx. Awesome! I can’t believe that didn’t end tragically. So Awesome!
Sometimes I think that I'm ready for the future with electric cars, but then I see an engine like this.
the sound of the pull chain light switch still gets me every time=
I respect a full episode every now and then. Thank you for releasing a fully. I understand nothing ain’t free nowadays but episode’s like this ill stay around. 😂
it was about time you broadcast whole episodes on youtube!! Love it!!
Yes! So happy someone is doing testing with nitrous and high octane fuel. There’s no one else who has tested methanol or e85 with nitrous
That was a joy to watch. So nice to see the genuine enthusiasm and pride as that monster cranked out both of 1500hp. Great video guys and congratulations!
A true testament to that motors assembly and parts. Throwing all of that at it and it kept taking it is unreal. Go 12:71 and 1700 HP is yours for the taking. Bravo Boyz!
My centrifugal C6 Corvette is at 750 wheel, has been for years. This video makes me want to do something stupid, thanks guys!

Awsome episode 👌🏾 i loved the : wow hes fearless with your engine comment 😂😂😂😂 😆👍🏾

Thank you MT. Ready to pay from EU for full broadcast, whenever is possible.

good to see a full episode
lmao thats 3 years old now.
Finally they realized that posting full EP on TH-cam is a better idea
Gale Banks is screaming at his screen saying “It’s air mass! It’s air mass!”
I think the dyno needs a Banks charge density meter and data logging for it.
@@danielkruger4305 charge density meter is just marketing gimmick. It used to be called charge temperature.
Man, that's a loud engine... I love it!
I LOVE ENGINE MASTERS. THE FACTS SPEAK FOR THEMSELVES.
I love these Engine Master sessions!!
I'd like to see what yall can do with a Steve Morris SML or SMX block and heads. Beast mode!
If I'd be closer, I'd offer to help out. Montreal Quebec here. Job well done.
Is this the best episode of anything on motor trend ? I think it is ❤️ What i would like to see is 10-14-/71 blowers compare to what you had right now.. blowershop makes those as well 😇
I'd like to see a carbed vs efi 10-71 to see the power difference and power curve.
Lets quit messing around and dump a 14-71 on it 😏
Or whipple 8.3 💪
You guys are great!!,good info, you're funny you keep me interested , I always learn from you guys.

I actually learned something new here thanks guys
"He is completely fearless when it comes to your engine!"
All these guys are Clarkson-level National Treasures.
That was a fun show.I have an intercooler a/w under my TBS stage 3 8-71 at 10% OD 446" 9/1cr so I can relate to this episode very much.
This is also why I added a 75 HP dry shot on my 2004 Acura TL with intake, headers, exhaust, six speed manual swap. They make 270 HP stock with a 11:1 compression ratio.
Methanol is your friend! combined that with 14-71!! take a look at air temps after the 350 shot. that shows you how much N20 it takes to cool down the air temps. good stuff!
I’m glad they justify my opinion on E-85. All I have is an F-150 with a regular 302 that run on flex fuel. Sucks in mileage but fun to run!
Would love to keep seeing these videos on my feed again!
need those headers just pointing directly out the side of something with the blue flames just peaking out. Thats great
Awesome episode! I would love a parts list & cost breakdown!
I'd say that whole deal there could be done for right around 25k! Just the blower setup alone with belt & pulleys is probably around 6-7k! Then the engine itself with the block, head's, forged guts, prolly around 15k! But you could save some here and there if you could find some used goodies. To go fast costs a lot of money!
Nice to see a full episode. And it was a fun episode
Great show thanks Please keep them coming.

I'd like to see a comparison between methanol and ethanol fuel with all else remaining equal, great show btw
That was awesome. Way to step up the jets without thinking twice, that’s when magic happens!
You've got to put that crazy beast in the impala, American Muscle music to are ears 🇺🇲
I love the fact they are using the A/F ratio with E85 and what Lamda or what ever it is. To me it’s easier to comprehend.
I love this show, roadkill and hot rod garage, but because of the app I can’t see it anymore over here in Belgium.
holy cow, I'm speechless and that's saying something my BBB 455 needs boost immediately...
Bigger blower = less overdrive = lower air temps = more power. This engine needed a 10-71 from the start. That's the minimum for anything over 540 cubic inches. It also takes more power to spin a blower quicker and that comes right off of the crank.
My Dream Motor for my Monza Towne Coupe is a Blown 540 Big Block Chevrolet. ❤❤❤❤
Hey guys, You should check out Interchillers. Using A/c to cool the intake temps. I guess it could help you push that diminishing return curve back
One idea for a show I have had is taking 3 motors; 1) very mild 100-200 hp, 2) 400-500 hp, 3) 1000-1500 hp - then dyno-ing them on the engine stand then in as similar cars as possible to demonstrate powertrain parasitic losses.
Thanks again for the episode 👌👌
Soooooo good! Team work makes the smiles work....
I watch the show all the time. I wish I could see some shows and testing on some Oldsmobile engines
E85 is readily available in the Inland Empire now, David. Not as much as gasoline but like 2-3 pumps per city.
A free episode oh wow it's a miracle

Best episode I've seen sofar keep the mates and fun in it
Boost is post-supercharger backpressure.
Boost pressure rises with nitrous because of the expansion of the nitrous as it absorbs heat.
yeah crazy no one talk about the intake temp on the last pull. 138! that's a cool temp!
I wonder if they were running up against the blower's efficiency curve here. I.e. adding more pulley just wound up making the blower's power consumption go up enough to wipe out most of the gains.
Which also raises an interesting topic: how would this play out at high altitude, e.g. on a Pikes Peak car?
The results of the switch to E85 is EXACTLY why I run E85 in my high power turbo Civic.
And bring the episode when finnegan and Tony win the hot Rod drag week with blasphemi from roadkill pleaseeeee
I want to see that go down the strip in your 31 model "A" Ford
Would like to have seen what methanol would have done for the numbers
Oh man!!!! Love this full episode!!!
Man, this was a great episode
59 seconds into this video and I'm like oh this is gonna be good!!
I hope that we get to hear it idle with that monster cam!
I wonder if you had backed it down to 9PSI on the blower if it would have still made similar power with the 350 shot of NOS, due to even colder air temps. Either way, awesome set up.
