I figured i would post a new topic to get right to the results.
Original thread https://honda-tech.com/zerothread?id=2158536


**********263 whp 173 wtq DYNO VIDEO************



Ok the results are in!!!!
The graph i posted in the begining of this thread was the car with 525 miles right off the street, tuned on the street with a 19" intake and filter, but i ran it for that run with a 34" intake with a V-stack which made the graph originally posted. Here is the results with the actual intake used in everyday driving, 19" long 3"diameter with a filter.
The car as of this morning has 1,000 miles on it. Until we changed it today the throttle body was a stock type R.

All runs on this graph were with the Type R manifold and 19" Intake with a filter.
Blue line is best today right off the street
Red line is dyno tuned




Every graph below here has the 64.5 mm throttle body!!

The next graph is mailbox vs Type R
Blue line is the mailbox
Red line is the Type R



Type R vs Performer X
Red Line Type R
Blue Line is PX
If your good you will notice the PX has efficiency spots at lower rpms than the ITR becuase the runner length on the PX is longer than the ITR.



Best graph yet by itself!!!




Mailbox



Performer X




Performer X not fitting again!!!!!



HEADER TEST

Ok boys here we go with some more pump gas graphs.
We dropped the full exhaust off the car and made a 2 foot exhaust to bolt to the DC header and the SMSP B20 vtec header. Both headers were tuned with the 2 foot exhaust. We kept the type R manifold and the same exact intake as the other test(19" long 3" diameter with cheap filter). Here are the results.

DC header with exhaust vs. No exhaust



DC header no exhaust vs. SMS B20 no exhaust



SMS B20 no exhaust vs. Dc with exhaust



Pro3's vs. Pro2's with SMS B20 header no exhaust Type R manifold




Pro 3's with typeR intake manifold vs. Pro 3's and a Victor X




Pro 2's typeR (Blue)vs. Pro 3's type R (Green)vs. Pro 3's Victor X (Red)



More graphs we finally got done testing the pro 2's with the victor X here are the results
Red line Pro 3's
Blue line Pro 2's



We made another intake manifold called the mailbox#2. It has the same upper plenum as the original mailbox featured in the original thread(see top of this thread). The sides of the plenum were tapered to funnel the air better into the runners and the runners were shortened 1.5" in total length. Here is the mail box#2 vs the victorX. Both have pro2's both with the b20 header, tested within two hours of each other.


Red line Mailbox#2
Blue line VictorX




The best TypeR Pro2 vs. Mailbox#2 Pro2 both with B20 SMSP header
Redline mailbox#2
Blueline TypeR




Here is the Mailbox#2 with Pro2's vs. Pro 3's and the VictorX




Here is the comparison Jenvey's vs Mailbox2
Red line Jenveys
Blue line Mailbox2







Here are the results that we ended up with that he will be driving for awhile.

Type R manifold DC JDM header Skunk2 Mega power R exhaust



This is the comparison from Greddy 60mm exhaust to the Skunk2 Mega power R 70mm exhaust
Red line Skunk2 70mm
Blue line Greddy 60mm

 

strong engine
good to see the difference in street parts verses race parts(powerband comparison)
great info

 

nice test!......... im assuming the ITR mani is stock un-ported, correct?

The type R intake manifold was only opened up to 65mm to accepth the bigger throttle body. Stock runners

 

damn the type r manifold is kicking *** in these test, suprisingly over there performer x

 

honda does there R&D for sure

Although, the ITR manifold got its *** kicked by the Performer X on 1.8 liter VTEC engines. I don’t know what to think anymore…is nothing constant?

Good tests though.

 

I would say X out performing Y depends on a lot of variables. For some set-ups, performerX is a better choice.

 

i thought the X would do REALLY good on the 2.0, looks like the R is doing pretty well

Hopefully it works really, really, REALLY well on nonVTEC B20’s with Crower 403 camshafts.
Mine was installed last week, will hit the dyno end of the month.

 

Looking good Mike.

Keep us updated, I'm curious to see how the VictorX does.

You will love the Pro3's. Big difference between the Pro2's and Pro3's on my 2.0L

 

Pro 3's vs. Pro 2's graph posted above!!!!!!!!!!!!

 

another difference in race verses street/strip(cam choices)

 

would that mailbox work better with the pro 3 cams? i wonder

Another nice test from Mike.

Mike, I suspect the B19 header would make comparable numbers up top while helping the torque curve over the B20. B19 headers are good for upwards of 260-265 whp. Plus they are better for the street.

I thought that myself, having had one for awhile and testing it on multiple cars, but someone sold it

 

point in case. performer x is a 1.8 liter manifold..not a 2liter.

 

great tests; saves me a lot of hassle for this season on the cam issue

and i know how you feel on that issue. i miss my OG header. BUt this new one is certain to make new memories.

 

Thank you for all your time for the tests!

couldnt agree more people will be using this test as a reference for years to come..

 

Thats a whole lot of testing. Looks like I should try Pro3s

 

Damn, you've been busy lately.

Another great comparison, thank you so much for sharing all of this.

 

More data for calibrating the sim.

Thanks

Could you explain this Furyof4????

 

Those are some interesting results. Great tests dude. Keep up the good work.

R manifold holdin it down.
