BANKS high ram vs. stock?

[OPoole]

is there any power gains or EGT loss in the banks high ram vs the stock air horn? on a 24v what are the gains of it

 

[Bob Wagner]

777Mechanic lost 15Hp on the dyno vs. stock airhorn

thanks Bob for the input i am a new TDR member my first post

 

[Bob Wagner]

glad to see you here

I run a Banks hi ram and I've heard all the stories, so next Saturday the 24th I'm going to dyno both the stock intake and the Banks. I'll post the results.

 

[Bob Wagner]

thanks jarhead

Like Bob I have heard you lose a bit of HP. Makes sense to me. When you allow highly compressed air to expland a bit then cram it back down just before entering the intake manifold you're going to lose HP. A better design would have been consistent ID all the way through IMO.

THANKS for all the input don't need to buy something that is not going to help. truck dynoed 472hp with edge drag, DD super mentals, AFE MF, ATS, kwik spool B1B, put it all to ground with DTT and 3. 54 1/8 mile 8. 50 82 mph going with F1 EDM nexts

Here is the proof the the High Ram gave me a 11. 28 HP loss vs. the stock air horn.

thanks for the proof!!! money is going some where diff.

What a great company!

anyone ever contacted banks

be interesting to hear their explanation...



i believe i saw a post from them about the record setting dakota



well banks? are you listening?

be interesting to hear their explanation...

I'd bet you will not get one...



I would be willing to bet it the runner size kills air flow speed and with the restriction on the manifold already the last thing you want to do is slow the air down more or disturb it in any fashion... . Andy

11HP is 2% of your 522 max. No atmospheric changes? No error in the data acquistion system? How many times did you repeat this test? Why were you able to get 7mph more out the Banks plenum?



Inquiring minds want to know?



I wouldn't spend my money on it because there isn't much bang for the buck regarding the pressure drop of the Banks vs the stock one and on a boosted engine the turbo makes up for the margininal dP loss present with the stock elbow.

because whoever was in the truck held the #2 pedal down a little longer...



expanding out and then necking back down does nothing but introduce an unecessary restriction.

 

[777 MECHANIC]

If you will look at the graph, it shows the times that the runs were made. As you can see they were 45 minutes apart. No temp change and no pressure change, no data equipment difference.

Forrest has it right about the pedal held down longer.

I also want to note that High Ram also lost 1 psi in boost.

I'd like to see more than one data point... ... .



The fact the operator held the #2 pedal down longer leads me to believe there are other variables that are not accounted for in the test set-up.



Banks claims something like a 50% reduction in dP for the High Ram. I've interviewed at Banks and I worked at Garrett with one of the engineers at Banks - they know their stuff. The fact that you lost 11 HP & 1 psi (measured how?) on one dyno run isn't a definitive answer. The fact that the High Ram expands then contracts to maintain the stock manifold interface isn't a huge issue.

have you ever run a dyno? unless you're some kind of robot, it's tough to kill it at the same speed... also, you're not looking at the readout screen most of the time, you're just sitting in the driver's seat watching the tach... at those speeds, a hundred RPM makes a big difference in MPH, and with those numbers, the revs were probably coming up fairly quick.



I'm not saying the Banks intake horn helps or hurts, but it doesn't look like it'd help much if at all...



Banks can claim all they want, it doesn't make it true... The people who sell Tornado Air claim a lot, but real world testing usually shows that those claims are unfounded...

Forrest,

I did my engineering co-op at Garrett Turbo and I spent 5 years at Honeywell Aerospace - I don't recall ever witnessing or conducting a test where we didn't repeat results or we relied on an operators 'abilty' to shut off at the same speed on a dynamic test. We usually tried to achieve a steady state condition and then record the data. No I have not run a chassis dyno. And quite honestly I don't hold a lot of faith in a test set-up like that seen on these chassis dyno's.



There is a huge difference between the claims of the Tornado Air people and Banks. Please don't insult the engineers at Banks by making this comparison.



Brian

 

[Forrest Nearing]

how would you recomend testing if not on a chassis dyno?



winding it out a little farther isn't going to magicly change the rest of the parameters... who knows, maybe they wound it out a little farther because the curve wasn't falling off, so they wound it out a little farther to see if it WOULD fall off... I've done that many times.



all I was saying is that "claims" are just that untill they're backed by independent testing, and all the testing I've seen of these intake horns haven't exactly backed up the claims...
