With e-throttle you could do some tricky cylinder deactivation to get not only more power when you want but more miles when you need.

Honestly when the information is as good as you’re giving us idc what the background is😂

[@ohcamsrazor1966]

So the humble LS 3 manifold is a bloody good thing. Especially $$ per HP.

[@crw3673]

Exactly! 1000+ dollars for 10 more horsepower and 20 pounds of torque.

[@asjmpickle]

The only parts I want to be bolting onto my truck motor is a turbo those individual throttle are cool for n/a show cars but like rich said they cost more than a whole race car.

[@ThePaulv12]

Yeah and the LS 3 curves are well curvaceous. More seriously you can see how much development went into it. The X Ram looks the business but who cares about the modest gain considering the cost?

[@asjmpickle]

@@ThePaulv12 a big high ram or mid rise ram with a single throttle body is good enough for me

[@ThePaulv12]

@nallen100 Look I'm hearing you. I have an old FJ40 Toyota 4x4 with a 350. It has an Offy X Ram on it. Totally ridiculous I know but I love it.

[@kwik440]

oh my god richard! Thank you for taking the time,and EFFORT to educate us!! I've dynoed plenty of stack injection engines, for sprint cars, etc. and the length of the inlet tubes is critical to the power curve, short ones, like you tested will lose bottom end power, but gain top end power, while a longer tube will do the opposite, also the bell on top of the tube is very important, with no bell it kills a ton of power all around.. crazy stuff for sure !

[@deanstevenson6527]

kwik440 : Way to Go RH at WTP. Yeah, stack length and 50 thou cam intensity works at odds, ITB Weber guys have reduced cam intensity and lobe center to maintain torque. One size fits all is the only way to compare. Mazdas 787B used variable runner length/telescopic tubes at Lemans, and you see a few guys making them work in racers. Ultimately, Italian Maserati and Aston Martin V8 Vantage style ITBs with proper air boxes and filters always work. It the time of fabrication and a lack of proper concept that inceases the cost of ITBs. See this telescopic IR trumpet system, typical of what some guys have been doing for years kzbin.info/www/bejne/gH65mqJ5Z716hZI

We were working with cross rams on early and late Mopars and Pontiacs back in the mid 1970's through the early 1980's. They worked extremely well. When adding a balance passage to the Pontiac, it performed better. The later Mopar's used the Edelbrock STR cross ram. It had different top combinations. 4bbl, 2 x 4bbl and 6 Pak.

[@TheProchargedmopar]

Hello Richard... great content as usual... got to love it! Regarding the Edelbrock duel intake manifold, it looks amazing but really..... do I want to spend a hole bunch of money to pick up a 10 -15 hp and torque. Then find out my alternator and A/C unit is right in the way of the sweet looking duel throttle body’s entrance. Then end up spending a bunch of money on relocation accessory brackets.... can buy a eBay turbo for less money and make a couple of Hundred horsepower more 😎.

[@rifleman7313]

What people fail to realize is the cost difference between the 'factory' LS3 intake and the edelbrock/down draft intakes. The Trail Blazer SS is just under the performance of the LS3 intake at a slightly lower cost as well (something that you covered in another video). What would be interesting is to compare performance gains per dollar (if all else is equal). Although this would take lots of research, time, and testing.

[@Dr_Xyzt]

The factory LS3 manifold has got to be the best factory manifold ever. Lightweight, low profile, relatively easy to work on, good design, good performance, sweet piece of hardware. If you look at it closely, it'll probably bring you a cup of coffee.

That X-Ram is a weird manifold. You usually don't see two "peaks" without VVT or variable runner intakes. The craziest part is it costs twice as much as the s475 turbo I just bought.

[@xozindustries7451]

Ya, no back drop is good, less call out words on screen better. It's great to have a talk dyno results on the speed parts, and like you said just because something picks up peak HP on a dyno doesn't mean that once it's in a car it's going to work the same, like putting air filters on the stack intake. Ask fining an how much power they usually kill. Great work on improving the videos, keep them coming.

[@azcamaro602]

You think it lost intake velocity with the ITBs? Sure those fancy manifolds made some more power but that long torque curve with a bit of a flat line for a decent 1000rpm i think is definitely the race changer.

[@ivorysoap]

I feel like the cross ram and ITB setups need custom tuning to get their potential. Otherwise, they're being run by an engine control unit that thinks a stock LS3 intake is in place and isn't tuned for all the extra air these two intakes are able to flow. Just my two cents.

[@dennisrobinson8008]

When they tune they adjust fuel and timing maps. So the ve is what matters.

[@danielrumler96]

No backdrop style definitely keeps your hands busy... but I prefer when your not as close to the screen .... can you use a selfie type stick to film?

[@lukestrasser]

Richard, I prefer the non backdrop format. Also for the price of the IR or X ram setup, if you want polished pretty goodness, but a Polished 2.9L Whipple. It will make more power than all 3 manifolds, and look good doing it. Bonus, you can use an air filter with it too.

[@thehappytexan]

Don’t like the backdrop myself either. I’m curious how the x ram works with boost. Nelson has his own version and has made some really good numbers with a pretty mild camshaft.

*I'm gonna be honest the stock lS intake manifold is the best.

And he is in the ls drifting for more than 26 years. I will use the stock one. Although the X-ram looks much cooler but the Price to Performance is pretty much the same. So the stock one, is one of the best for the budget guys.*

Hey Richard, are we going to see some BBF stuff in the near future? Just picked up a '97 EFI 460 for my nephew's 1980 notch Fox stock suspension H-pattern drag car; going to get at least an intake for it, preferably something that will work with the stock harness so we can run it via Holly's new Terminator X plug n' play factory replacement ECU, but we'll likely throw a set of heads and cam/valvetrain on it while we're at it. The plans include a big single hair dryer sooner than later(yea, a turbo big block stick car on radials - we are indeed gluttons for punishment/plain ol' fools... but who doesn't like a challenge?), I suspect that we can get a decent lifespan out of the stock bottom end at ~700HP, especially with modern EFI to help keep the AFR in check/(hopefully)prevent nuclear meltdown. I would certainly LOVE to see some stock block BBF stuff though; or ANY BBF stuff for that matter(never know when you may end up being the owner of an aftermarket block...)! Loving the content so far, EXACTLY what I'm into! It's rare that you even get to see higher end, less common intakes like these actually compared to other intakes, let alone the other competitors of this market niche, it's nice to be able to SEE whether or not the 'bling' will actually pay off, much appreciated insight!

[@JobSpetter]

The IR manifold had too short of a runner for the intake port size and camshaft selection. You have to select runner length for a target RPM to get the maximum from wave tuning.

[@nocturnal0072]

This is true, but I imagine most (more that half) of the people buying stacks are doing it for looks. Edit: the short stack is probably why the power is all up top.

[@dewaynejorgenson1093]

Id really like to see the 8 o2 set up on this. Honestly that should be standard on all the tests from now on in my opinion. I never thought there would be such a difference in afrs cylinder to cylinder. Im trying to figure out the most cost effective set up to put 8 widebands on my car right now.

[@averageamerican4478]

The one thing about the edelbrock that bothers me is the drastic change in size from a single throttle body to two, maybe the engine needs that much air flow to breathe, but has anyone tried or manufactured smaller throttle bodies, I feel like their would be a loss in air velocity. In your opinion, do you think the engine is maximizing efficiency with the 2 stock throttle bodies? I was thinking about trying to ask a machining buddy to make an adapter that would be like a convergence adapter, maybe cut the inlet size to 60-70 per instead of 92 per throttle body. Or is it that the factory is just not putting a large enough throttle body on at the factory? My dad used to build race car engines in the 60-70s, and now he teaches students about jet engines and prop plane engines, we were discussing convergence and divergence, because I saw an article that dyno a set of heads that had smaller valves that pulled more power than a set that had large valves, in their case the smaller valves won out, to me that would mean the engine must have needed more velocity and less pressure, I am wondering if this manifold could benefit from the same? Sorry long question, I just love paper drag racing and living in the theoretical.

[@richardholdener1727]

Larger throttle bodies have no negative effect. A smaller throttle body does not increase velocity into the runner or combustion chamber. It only restricts flow if it is too small. If it is too large-not happens except over sensitive tip in

[@eformance]

So what you're really saying is that the LS3 manifold is the best overall manifold for this combo. I certainly wouldn't give up all that power under the curve for looks. The Edelbrock manifold didn't provide enough difference to warrant the cost IMHO.

[@paulguerrero972]

Great video Richard! I love how computer control has vastly improved engine performance. In my day, for street applications, one had to be careful not to over cam, carb, intake, headers, heads.....Speaking of intakes, have you run a dual plane/180deg FI intake? I'll assume, since stock intakes seem to use a single plane design, that there is little to no advantage of separating intake pulses. What say you.
