PHR Billet Intake Manifold DYNO RELEASE!

[nateTT]

SUPRAMN do you mean the fuel system is different in the 2 setups so the 18hp gained could just be duel to a slight fuel system change and bigger injectors etc?

certianly looks like an impressive bit of gear but i think aesthetically its a long way off the more curved JUN style plenums from hypertune, JUN and VW.

The only thing changed is the injectors as they would not fit both rails. The injectors used on the hypertune are very high quality 1000 cc injectors so way more than enough to handle the levels they were tested at. Dumping more fuel in it would not make the car run well at all let alone gain 18 HP.

Just so I am clear on this too. I did all this dyno testing totally independant on my own and paid for all the dyno time and back to back labor out of my own pocket so that i could get a true test.

Everything has been very fair and there were no tweaks or changes to make the PHR manifold look a little better on paper. I have nothing to gain from it so that is why I paid for it so there are no questions that the tests are not accurate.

what sized tb was on the hypertune, what size on the phr manifold?

Trying to ask the important questions here = )

[SUPRAMN]

90 on both

[Daniel]

I have 2 independent fuel systems. one rail feeds my pump gas and the other rail goes to my race gas tank. It is easier to tune on the map with all injectors being the same size instead of 6 injectors being 1000 and 6 2000.

Back to back was done with a Garrett GTX 4202R

Pictures have a comp turbo as that was put on after the dyno as I am doing some testing on that turbo.

Congrats on Hitting 1K with the 76mm
Nice to see that Comp Turbo on there and looking forward to seeing the results Against the Garret...It Should be a Fun Test..How soon for Updates??


joeatPHR-Im Very Interested in the comparison with the Veilside Intake.I'm Sure yours will produce more HP since it seems that the Veilside is usually at the bottom when compared to other Mani's these days but im interested in just how much the Difference is.

[REAL JDM]

sorry misinformation jonathan. For clear things up.. both intake manifold WERE done with ID2000. that was only way to do the test without wiring up another injector plugs. since ID2000 injector use EV1 or equivalent, therefore, we made sure it is same injectors on both intake manifold test. And main reason so less variable.

test were done with garrett GTX 4202.

just testing result, PHR, hypertune, jun, wv, alll aftermarket intake manifold can increase the potentional of its set up. however, how to effect on how much torque, and makes power at where and how much powerband its very different by the length of intake runner, as well as its volume. but knowing that PHR is the only company that went in to R&D to come up different runner design than most other intake manifold. For that matter, its very worth of money although its not cheap but controlling/adjusting fuel/air mixture equally which makes better for motor not just a number of the dyno graph.

Veilside is being done here on Dustys car. - V8 Killer

Thanks,

Cant wait to see some more data on this thing. Looks like a nice piece

Thanks for clearing that up. I thought you had used the previous injectors that were in the hypertune. Doing both with the same ID2000 injectors is best and takes any doubt about adjustment in fuel system as a factor for change in horsepower.

[Powerhouse Racing]

The tests were 100% accurate with no inflation. I didn't handle these tests at all just told him that I wanted a back to back comparison. If the #'s weren't better I would have been disappointed but Jonathan would have still posted them up.

awesome,Thanks for the update

[Northstar]

Awesome results.. grats to PHR on making a very well designed intake mani.. I look forward to the other dyno results.

[Jstaats]

Will these newer Wison TB's line up to a 90 mm Accufab? I need to get rid of my leaking Accufab and Hypertune is $$$$ and not sure it will even work. Please let me know.

They are the same bolt pattern. I've lined up one of the 105mm wilsons to my 90mm accufab.

[Jstaats]

Hell yeah. Need to call power phr on monday. Thanks

[Powerhouse Racing]

Let me know!

[SUPRAMN]

Here is the race gas dyno. This was not done on the Garrett. This was done on a custom Comp turbo with a quick spool valve. 31 LBS was max boost on this we will go for more when I change wastegate springs

[Daniel]

Did u dyno the Garret on High Boost as Well???

[SUPRAMN]

No

[Hukhuksupra]

I guess you let off around 7600-7800rpm?
Why not rev it out more?
Great power on the unit. Can you please post whether the compressor is in the 70's range or the 80's range since you cant say the exact specs?
Thanks

[REAL JDM]

its pretty much equivalent to gtx4202 and keeping that size will make fun street car .

I did not know you change the screen name sorry mate.

how is your car coming along.

Cam selection was specifically designed and picked so jonathan will have more pick up power on street, and transition/response. we could easy pick up more power by putting larger duration/lift of cams, and degree it so it will make a power. but GSC s1 cam is not design to flow over 71mm turbo which I know the fact but we picked the S1 cams just because simply in my book best street cam there is available.


To make more power, and more overlap, more lift .. bigger turbine, housing ,,, that is easy part.

next time around we will change set up after jonathan gets to ride in car little, and enjoy the car, and then we will have set up ready for Texas.

let out of early on rpm because if you notice, HKS crank has longer stroke than regular brian crower, which I dont really remeber how much is different. but keep it rev at 8000 is where it should be.. it should be fine with 8400rpm some times but we were told by hks to keep it around 8000ish. plus cam is not operating efficiently at the rpm which is why I didnt go pass 8000 many times.

[2j1988supra]

damn awesome results..

[Daniel]

No

That wouldve been nice to see how much HP that Garret did at the same 31psi..so,Since the car did 733 on the Garret on pump.
What did the Comp do on pump?? It would be nice to see how much More OR less HP the Garret made over the Comp.

btw What were the Flow Numbers for the PHR Intake Mani??
Here is the Veilside Numbers below:

[REAL JDM]

daniel. you pay dyno time, and my tuning time and labor to do back to back then, we can do garrett high boost set up on jonathans car. but I dont think that is going to happen. and intake manifold back to back was pretty pain enough. lol.
But back to subject. PHR intake is really nice and very well engineered unit, definitely better overall product then 15 years old designed veilside manifold for sure. besides the cost difference.

[rwppowerful]

I think Ill just save my $3k and make that kind of power off of the stock manifold and still have no drivability issues....after I hit up SP with the pro efi that is....


Forgive me but by the looks of it it is made of flat sheet aluminum which doesn't take much talent to make in the first place......so yes as stated above PLEASE PASS THE GOOD STUFF THAT IS BEING SMOKED IN THE SHOP!!!
