[@ronn147]

Alright I know this video wasn’t directed at me but it sure answers a question I had and something I said a while back on one of your videos. I’m running a performer rpm dual plane with my procharger on my bb mopar and I thought I might be leaving a lot on the table without a single plane but this shows most likely I’m not. Thanks for another great video and tech help!

[@evilinside5984]

@ronn147- Depends on your RPM window, that you utilize. Example: If your setup would like to be shifted between 7,500 to 8,000 Rpm, if it had the single plane, & you had a 6,000 Rpm tq. Converter, then yes, you would be leaving a lot on the table. But your cylinder head runner volume, & your camshaft would also have to support that Rpm range. Most setups on the street are not that high strung. That is why the Dual planes are usually the best choice on the street, for there average Hp, & Tq..

[@ronn147]

@ well said and right after I posted that I forgot to put that I only run mine up to 7000 rpm. You’re 100% right if I was running it to 8-8500 I would definitely be losing out. I watched the video and thought oh look about the same rpm I use! And I forgot to put that lol.

[@TheReinoPaasonen]

Finally you have shop for parts!

[@jasonbirch1182]

Oh ive been inspired! Thanks. Ive been trying to figure out how to create a good port shape for a custom Mercedes v8 intake manifold. I love the lsx runners. Im going shopping for a set momentarily. Plus the cross ram inspiration to use two of the restrictive v mounted plemums hanging over the valvcovers. The throttle body openings will be pointed right at each other so a y pipe will be perfect for the single throttle body and CIS K-JETRONIC airflow meter. Ive been talking to a foundry about casting a carb manifold too. Id love to see you pull a 420 or 560se/sel m117 v8 and run it on the dyno. Im almost complete a HEI distributor conversion too.

[@BigEightiesNewWave]

GM did the same for tuning back in the Eighties, with the long-tube TPI intakes.

[@BigEightiesNewWave]

My Lingenfelter box ram on my 383 did same, best of both worlds. Early 1990s

[@randallsavage3795]

I thought that performance design intake was supposed to be the newest best thing that didnt sacrifice low end for top end. I currently run a long runner lsxr102 and would need to see 30 -40 hp to justify the expense of switching

[@grpweld]

You just don't see many good results from the P.D. XS intake. I have one on mine for a bit now, runs great at wot but never had good luck with overall drive ability. Even would stall at times coming off of idle. I'm going back to my stock rod modded intake

[@krusher74]

@@grpweld when a big throttle body open it makes huge cfm flow suddenly and you engine does not get enough flow, runs lean for a second and stalls, it called tip in, you need to add extra fuel at that moment. "You just don't see many good results" because people don't know how to tune out probemsm juest blame it on the part!!!

[@JamesCopeland-i1j]

ITB is the way to go. You get better throttle response, and just swap horns/ducts for the best result.

[@C5Z06CarGuy]

Another interesting intake manifold test would be to put oxygen sensors on each individual exhaust runner, to see how each intake distributes airflow between cylinders. According to Brian Tooley the Equalizer and Trinity do that much better than most LS intake manifolds.

[@richardholdener1727]

see the nitrous distribution video or the single vs dual plane vid

[@Drunken_Hamster]

I would think that some sort of crazy "180-degree" cross-ram intake manifold would do even better than that, much like how 180-degree headers improve scavenging. It's always those two damn cylinders that fire back to back (90 degrees) from each in the same cylinder bank other causing problems on cross-plane V8s.

[@driftergonewild]

When will you test Texas speed Titan instake! 😊

[@bcbloc02]

I assume the fuel injectors were at the head end of the edelbrock cross ram. I wonder how it would run with the injectors closer to the plenums?

[@richardholdener1727]

if we moved injectors farther up the runners toward plenum, they often make more power

[@yeahididit9054]

That Edelbrock intake is Bad@$$ Did it change the way the exhaust sounded?

[@grandpagamer697]

You should do a test on the new Summit "Max EFI" cast intake manifolds. They seem really nice for how much they have them listed for (under $500). I'm considering getting one for my ls3, but there aren't many reviews on them.

[@zztop7306]

Have you ever tested a Harrop ITB set up? I've always thought it was a slick set up but the price is hard to swallow

[@richardholdener1727]

they do look cool

[@KZ-se4ik]

Was really fascinated by the NA vs. Blower manifold comparo. While the trends were the same the single plane manifold lost a lot less torque (absolute and percentage wise) down low when the blower was in place. I guess the extra air mitigated the sacrifices of the single plane.

[@richardholdener1727]

incorrect

[@ChurchAutoTest]

@@richardholdener1727 Help me out Rich. Are you saying KZ's rationale is incorrect, or the observation? Just eyeballing the graphs looks like the NA setup had the single plane drop from over 340 lbs-ft to under 310 lbs-ft at 4400 rpm. And when boosted it went from about 425 lbs-ft to 400 lbs-ft at same rpm. I mean the losses look pretty close (without knowing the actual numbers), but that would make the percentage drop smaller on the boosted setup.

[@johnclary729]

Still hoping flr that long-duration cam on the long runner manifold test. People keep telling me a long duration cam won't work, but I can't find any tests where anybody has tried it except for that TPI manifold shootout Richard did several years ago where he cammed for the short runner manifolds but ran the long runner manifolds on the same cam. I noticed that the long runner manifolds carried power well past peak power without a lot of drop off. I would like to see running a really long 280-290 intake duration at .050" and even more exhaust duration and see if peak and average power come up and carry well past peak torque like what happened with the ported TPI manifolds.

[@richardholdener1727]

it would idle and drive terrible with a 280 @ .050 cam

[@rocketsurgeon11]

What were the runner lengths for each of these?

[@craigpennington1251]

All depends on how you drive it & what it's in.

[@krusher74]

How about running some CFM flow numbers on the heads. if the head is flowing 200cfm, doe it make any difference if your intake can from 220/250/300? you can offer he engine more air thought he inlet but if the head can flow it I would expect it to be pointless.

[@chriswise1232]

Looks like we might be money ahead to port a TBSS vs buying a FAST.

[@Kstang09]

There's not much meat on the bone porting the stockers...

[@chriswise1232]

For real. The colors used to be the same on each engine combo. Now the hp/tq on all the combos are the same. Makes it a bit more difficult to read between the lines
