getting ready to head back to the dyno to do some back to back pulls w/ the stock mani vs skunk2 vs euro r

bump to the top to get some more viewers

i would think alot of you guys would be interested in seeing this test performed, no?

 

bump, good stuff!

It's been done before, but another test can't hurt. Surprise us.

 

Euro R>Skunk2>Stock

I'd be curious on atleast one run with Stock if you hook up the secondaries properly or to Vtec with a sol. to see what the torque would look like...

 

yes, normally the resutlts we have noticed in the past would seem to suggest that the euro r works the best, especially on a stock internal motor. the skunk2's larger plenum and longer runners cause a loss in velocity im sure and this is most likely the cause for the midrange loss'that is so very noticable on the street.

i have every intention of using the euro r after this test which is why im installing and testing it last. i already know it works the best on a stock motor but we figured since i am going to the dyno anyway we might as well test out the skunk while i am there to see the exact differences

my application is strictly drag race only, so we want to see the exact differences in the upper half of the graph where it would matter most. i still believe the euro r will be the best choice for my currently stock motor but i wouldnt be surprised to see the skunk manifold make the most peak whp given its larger volume. the question is at what rpm will it crossover and beat the euro r?

if there is a decent peak gain, i wouldnt be surprised to see it even more so on a fully built motor needing more volume. i am planning on building a 300+whp h motor soon and am curious to know if the skunk manifold will be worth my time testing on the new motor.

we also have another prototype manifold which we are working on that will be tested on the new motor, but i dont want to put a hundred dyno pulls on the fresh motor before it even goes to the track so the testing will be limited to most likely 2 manifolds. if the skunk 2 shows promise i may choose it over the euro r to test on the new motor along w/ the prototype when the time comes.

as far as the iab's in the stock manifold are concerned, yes they will provide the best low end drivability on a stock internal motor dd. however they are an obstruction to air flow at high rpm and hinder peak performance. the h22 already has plenty of low end tq and this is why we always delete the iab plate from the stock manifold whenever we do an h swap.

 

 

I have an ENDYN ported Euro-R intake manifold that I wouldn't mind putting to the test against ANY intake mani on an H N/A or N20 setup. When are you testing randy?

that sounds like a nice manifold. i may be testing as soon as next week, i will know for sure later this week.

Let me know when. Are you tuning at tempest or PSI?

 

i always go to tempest. i will be giving joe a call later this week, then i will let you know.

 

I wonder if anyone will test the BTP3 that I run....I would love to see a comparo with it against stock and a EuroR

 

here are some pics of something else we are working on as well:

 

Damn! that's crazy!

 

wow those walls are thin.

any way you gan get a blacktrax manifold involved in this? i got a stage 4 for boost so i dont think you would want to run that.

Cool. Hey will prelude header work ont he H2B hatch setup? I know there are clearance issuses. I have my Hytech spec II Header also ( dunno if your current motor has enough ***** to utilize it though J/K ). I am going to be swaping out that manifold and header on the street car this week so depending if I get it done or not you more then welcome to them both for testing


P.S. I have this also:


Before you ask you know how I am H23

it depends how long the exhaust manifold extends past the rear of the oil pan. it most likely wont work for my swap. i have been speaking w/ john about making a tri y for an h2b, maybee i will have one next season

o ok gotcha I am getting a skunk 2 intake mani friday so i'll have the euro R off the car next week forsure. Id like too see what it would do vs a stock Euro-R and other manifolds.

 

Dyno appointment was today at 4pm

His original baseline (in his sig) was 216/166.

Randy just sent me a text.

Little bit hotter out today.

Same setup made 213/166 today.

Skunk manifold made 5hp more than that after tuning.

Euro R Peaked at 220hp and gave more mid range, but the Skunk carried the power longer

I'm sure he will be on later giving the full update

 

yup, the testing is complete!

the results are in the original thread here: https://honda-tech.com/zerothread/2351032 check it out for pics and graphs

and to sum it up the skunk and euro r manifolds both peaked at about the same whp/tq however the skunk manifold carried the power longer but the euro r had alot more midrange power.

so it looks like its going to come down to track testing these manifolds back to back to find out wich one will get me down the track quicker stay tuned

 

Told you to keep the Euro-R on over that Junk 2 . Good passes

i was able to change the lamda settings to a/f and pull the logs. turns out the a/f was in the low 11's the whole pass lol. i will be track tuning each manifold next time

That what they all say.... Just imagine how good the Euro-R will be with a few more tweaks.. I still think it's the mid range torque between the shifts thats keeps u going and got you the 12.0 pass atleast on this setup maybe on the "new" motor the bigger primarys might work better just not a big fan of Junk2 . But we can still test it against my euro-R on the big motor

 

I love the euro-r's
