VTEC TURBO TEST-HONDA B16A INTAKE TEST-STOCK P30 VS EDELBROCK VICTOR X-WHAT WORKS BEST UNDER BOOST? 

This is what I’ve been waiting for my whole life

Excellent knowledge .... Honda did their homework here. I am building a 2,3 Ford OHC and I plan to carry this knowledge forward.. Thanks Richard

The graphs are zoomed in too close, so the edges showing the scales are cropped out. Noticed it in the previous video too.

These engines are so efficient and to think they were designed in the 80s , when most domestic v8s were making 250hp from the factory .

Love that you put a test like this up. I’ve gotten away from imports more and more over the last half decade or so, but back when I was building my boosted Hondas I always wondered about the Edelbrock manifold. A ton of guys were running them and but I never personally used that piece or tuned a build with on bolted on. I typically stuck to Skunk2 manifolds and even always had good luck with some factory Honda units but the Edelbrock was always something I was curious about.

Richard, I own a del sol with a JDM B16A SiRII with a P30 intake and I can tell you this - this engine is incredibly well designed. Who tries to change the stock intake, camshafts etc must know very well what is doing. As it is as stock, it's perfect.

Also, I know many people who went with the Victor X manifold on their turbo Honda drag cars, but I always went with a Skunk2 manifold. I have a fully built LSVTEC turbo that makes 709 whp with a Skunk2 3.5L Ultra Race manifold with a S2 90mm throttle body.

everyone loves a lil 4 banger! even if they say they dont

I have this same engine in my garage with Wiseco 9.8:1 pistons, Eagle H-beam rods, and a Cylinder Support System installed into the block. I have the matching PR3 head and Integra GSR cams for it.

Richard thanks for doing this test, it confirmed what I thought about the two manifolds. I used the stock manifold for my build. boosted vtec B20.

This test is alligned to my interests! Happy New Year! 🥳

Happy NYE, thanks for the great content!

Thank you Richard for the great content you give us you have a happy New Year as well.

Happy New Years Richard Keep the Good work going 👍👍💯

B series cam test 🙏🙏🙏🙏 I'm wrapping up my b16a2 build should be about 400-450whp in a 88 crx! Excited!!!!

You’re the man Richard!!

Should have posted up the IAT differences between the two manifolds. From my experience going from a 70mm throttle+skunk2 pro, which I think has a 1.8L to 2.0L plenum(long runner) to a 90mm throttle+ skunk2 ultra race with the 2 litre spacer giving a total of 5.5litre plenum(short runner) there was an IAT drop from 40°c/104°f to 30°c/86°f with the bigger plenum. But you're right the motor felt sluggish on the low cam but boy did it haul ass switch'n over from the 190°dur to the 270°dur, 12.7mm/.500 lift. What I found in the logs was that it wouldn't reach above 100%VE (98kpa) till the vtec point (101kpa) 5200rpm so I did some research on Helmholtz resonance and the relationship between large plenums and tiny(bottle neck) openings. Found out that going such a large plenum of 5.5 litres required a much smaller throttle opening, hence there was a larger "AIR SPRING" with a larger plenum. So I got a pvc plumbing reducer that was 90mm to 65mm in diameter but the 65mm section was only 2'inch long with 1 foot of 65mm diameter pvc pipe, as I read somewhere that for peak torque at 6000rpm you need a ram at least 13'inch long and going 1.7'inch shorter would push the tq peak higher 1000rpm and obviously 1.7'inch longer would bring it on 1000rpm earlier. but I wanted to shift that higher so you couldn't feel "the drop off" so I ditched the ram and just left it with the 65mm opening. which I hid in side a 100mm aluminium heating duct(my cold air intake lol) and viola! I picked up 7kpa (105kpa) from 2500rpm all the way out to 9500rpm. I couldn't believe this thing was naturally boosting it's self with 0.5psi of boost lol. And the injector duty cycle% 310cc injector and 55psi on the fuel regulator.(AFR) had to be corrected 7% at cruise, 18% partial throttle and from 76% to 97% at 9500rpm WOT. Which was a 22% increase in fuel required at the peak. Which tells me there was an increase in 22% air flow at the peak given the same AFR. 14.2:1cr,skunk2 tuner3 cams, b20v, 93octane, pro manifold was 211hp> 240hp same setup with the larger manifold with the IAT drop and the help of Helmholtz boosting.👌

Love the honda vids

Bro I knew when I saw you uploaded a Honda video we would hear R-Tech kick in lmao.. the other videos as well.. saw them just didn’t comment 👍👍

To the new year and beyond!

Hey Richard, Kinsler fuel injection makes a cross ram ITB intake for the LS7, it looks like they have as much runner length as the cross rams from holley and edelbrock, and I think it's worth a test!

Happy New Year Richard!

Please do more 4 cyl. turbo stuff. We don't want to be left out.

Thanks for sharing

You know me I love the B series stuff curious if you have anything on the Performer X vs the P30 or Victor X

Richard great video. But we can't see the left scale data

I just found out today nissan has twin screw superchargers available for the qr25 engines made available by the new qr25der supercharged hybrid found in infinitys and nissans. They rate the supercharged 2.5 qr engine at the same horespower as a 3.5 vq. You can find these blowers affordably online and it should bolt on to any 2.5 altima, sentra, or other nissan/infinity vehicle.

Any honda J35 videos?

Could you try and do a Toyota 1grfe v6 on the Dyno

Dyno pull sounds please???

What are the comparative runner length and volumes? Just curious.

@richardholdener anyway we can get throttlebody comparison of the new icon 102 throttlebody against the nickwilliams and fast 102mm theortlebodies?

How about 4g63 stuff? I have a Magnus on mine, but never seen a comparison with Mitsubishi stuff.

Are you using something with duty cycle for a boost controller. Change your boost/waste gate adjustments it should bring some of those curves into a different curve.

To be fair, your using an intake manifold design that's more ideal for peaky big turbo, 600+ HP motors, with a turbo kit made for a much more linear, lower HP. Same thing happens when your taking running say 2" hot side IC piping and 2.5" cold, vs the guys that run full 3". Unless your running massive massive power, there's no need. The pressure drop and extra time to fill the piping and manifold before you start getting positive pressure is drastically increased, and therefore, laggy.

I know it's a little different but you should try to get a hold of a olds 394

B-Tech! B-cause, Everything is B-etter with B-oost!!!!!

I’m currently making 611whp with a p30 intake, I can attest to how effective they are.

I knew the victor x was killing power but I put one on because of the cool factor 🤣

2:27... because Honda... Short runner intake manifolds are for upper rpm ranges..trying to get power down low will not work...

Do you can any testing with the Mitsubishi 3.8L v6 when adding a turbo??????

Sweetttttt

I know it’s totally the wrong size engine, but would would something like a mini bike with a small 212cc motor have such a “short” intake runner? The carb is slapped directly to the head with maybe 2.5” to the backside of a valve. Most mini bike engines without heavy mods won’t be revving over 5k. So wouldn’t they want a longer runner so they can make use of that torque? Perhaps it’s merely for packaging reasons. Idk a bit of a tangent but I’d love to see how it would work out for our budget DIY people that use mini bikes and motorcycles as our engine building

Have you done much staggered vs same lift/duration cam testing on dual overhead cam engines. We often run same lift and duration on RB26, but I haven't done enough real thought about it to know if that is the right way to go.

Any 4g63 1g and 2 g and Evo 4g63 as well

You should follow that up with a cam to match the intake then you will see the added power from the vic with stock cams it cant take advantage of the extra flow!

Hey richard would the same thing apply to a tubro b20b16 head itr cam rev limit 8000 9 psi, im trying to decided if i should keep the b16 intake or upgrade

Richard you don't leave much to the imagination your so through. You ran 91 and 100 octane you usually run e-85. Are you able to get pump e-85 in California? Can you elaborate on the scarcity of e-85 coast to coast and it's future? As always thanks for your hard work.

Hi Richard, have you ever test on dyno which one is better, high compression ratio with retard timing or lower compression ratio with more timing? For example, lets say: - Honda B/K series engine - 11:1 vs 13:1 (similar piston weight, because lighter piston make more power) - Same internal engine (rod, crank, valvetrain, etc.) - Same fuel (98 RON/ 93 US octane) - Same ECU Thanks

being a stock engine and a b-series I'd assume this engine will detonate very soon? with those power figures, boost numbers and stock internals I just don't see it lasting long. I have to ask are your engines built to handle the numbers you show, or do you just give it all she's got on the dyno,then detune it for longevity?

Lol I've known this all along, I've been tryna tell people. It's the same with the big ass magnus and ams intake manifolds evos guys run. Skunk2 and oem is better every time for street setups

Do a K-series vs 4G63T 6bolt need two blocks one for how much they can make stock blocks vs built

How do dyno shops handle blowing up a motor? Do they cover the cost via insurance or do they just have the customer sign a waiver absolving the shop of liability?

Srt4 engine would be nice

I am having crazy boost creep,I have a gsr / b16 head fully done super tech head,gsr cams ,ram horn , 44 mm wastegate ,1300cc injectors , hondata v3 , an only happens fro 5 to 8 thousand

What size throttle body was used? Or did i miss it being mentioned?

Can you do a b18a1 turbo and then a ls swap on the b18a1

👍💪

Amazing to think Honda could put a warranty of these little screamers. Happy New year to one and all 😷😂

You said it was running on 191 octane???

Have you boost a coyote before?

Mopar 2.2/2.5 sohc engine that came in everything from k cars, lebarons, Daytona .

Hey Richard, I think the power dip around 5200rpm may be negated a bit if you bumped up the VTEC engagement point. Do you think the Victor X would come alive with a higher output turbo motor or is it really suited for high RPM only?

Are you the guy from Pinks the tv show?

VTec Yooo

What’s this “the best cam” I hear about you testing 😃

Richard I gave you a thumbs up but the Honda crap is not interesting. FWD is PoOp.

Happy New Year's

Personally I blame squirrels
