PHP Intake Spacer Dyno Results

[Double"O"]

Alright i hope this helps all of you who are trying to decide on whether buy one of these.

i didn't loose any power up top but i did loose a consistant 3-8 RWHP from 2k up to 5700 Power did increase from 6400 to 6800 but +3-5

I lost 4 TQ at peak and a 4-9 RWTQ from 2K to 6800

My A/F stayed pretty good


My car now hitches at 2k in each gear and has backfired a few times as well

In short i am pretty pissed about it

Hmmm.


that's not consistent with other reports i've seen... sorry to hear that dude...

 

[RioRed4v]

yea..not consistent with what i've heard also.

any reason why it might be running like that?

 

[Double"O"]

I don't know what the hell is going on with it

We torqed the bolts to specs and everthing sealed properly.

The guy the owns the dyno said another 01 Dynoed with the spacer and pinged really bad. Mine didn ping but she ain't running well with it

 

[AzDropTop]

Weird? A bummer really. Sounded like it was a good cheap mod for a little HP? Seems others were talking about gaining HP and TQ down low? Keep us posted...

 

[RioRed4v]

yea..i heard it was nice mod for some low-end power.

i was all set to pick one of these up, now i'm a little hesitant.

OMG! I was planning on ordering one today. I would have ordered it on Friday if I wasn't so lazy. Now you have me thinking about this. Machs have reported good gains so maybe it's due to the differences between the way our intake is and theirs. I have no idea, it's just a guess. I don't even know if it's different. It's a guess on the way they have a shaker hood and we dont. :shrug:

I'm glad you did this. Some people think it's stupid to waste money on dyno after doing a little mod that you weren't going to get huge gains from anyway. You never know what a mod might do.

I saw that mod on Paul's site and nothing but major doubts crossed my mind about it....I dont find anything enticing about it because the spacer in the wrong area to even be affective, basically too far from the air fuel mixture....My advice stay away from the tornado as well:-D ...J/P..DA snake boy!!

 

[GreyAsp]

What's the supposed reasoning behind this mod?

In theory, its supposed to give more plenom volume and a more effecient fuel intake charge, basically what a phenolic spacer will do for a GT40 intake on the 5.0 push rod stangs....basically more torque is supposed to be the end result, and a little more big end rpm...DA snake boy!!!

Even though I can't use it on my car, when I first saw it I thought it might cause problems for most cars depending on mods. I think it looks promising for cars with forced induction, but I think that it would decrease intake charge velocity due to the way that the intake is designed. The 99 and up cobra intake pretty much just rolls over top of the runners from the throttle body side over to the opposite side. All I see this thing doing is taking away the smooth contours of the intake and making turbulence. I could be wrong, after all I haven't studied the 99 and up intake that much yet. I look at it like this. Say you have a 1 inch water line going straight up a 1000 FT hill, and a 2 inch line going parallel up that same hill. Both are being fed from two identical pumps that flow the same rate of water. At the top of the hill which one is going to have the most pressure, or velocity I should say. the 1 inch line of course Now double the charged output of the one feeding the 2 inch pipe, and not only will you have more volume, but quite possible more pressure. I look at the way our intakes flow the same way. They will do only what they will do until they are either ported polished, or force fed. Until then their efficiency is about as good as you can hope for. The days of slapping a spacer on you 351's intake and gaining serious hp are over with the engineering that we are seeing in cars today. JMO.

 

[01BlackSnake]

What about all the cars that have gotten power from it?

 

[Double"O"]

I saw the spacer yield gains on a Mach a few weeks before i ordered mine. Thats why i ordered it, apparently my car doesn't like it for some reason.

 

[HISSMAN]

As I said, it depends on what you have done to it. If you increase the volume of air feeding the system, AKA CAI or something else, then you might see gains from it if your car is set up the right way. There are just a lot of variables to take into consideration to put out a blanket statement and say that it adds HP to everything. I have talked to about 8 people that have used it, and 2 saw gains, of wich 1 saw great gains of about 8 hp and 5 tq. 4 saw no difference, and the other 2 which do not include anyone in this thread lost power, Of wich one of those had to remove it because he wouldn't hold idle and had no way of tuning it. It all depends on the car. Cars are like people these days. They are all different.

Hissman,

My car is idling a bit higher since the install, and it runs very rough at 2k.

On a side note i did spin the dyno to 160mph at 6900rpm lol

What about this mod and a ported/ polished intake?

ya, what about this mod on a p/p intake manifold? hmmm, now im a little hesitent about this mod. i was very interested in looking at it. but i was waiting to hear power gains.

This give and take is really interesting. I'm using the PHP spacer, and outside of the problem with the EGR fit in getting it installed, I haven't had any of the other problems mentioned. And while I haven't had the engine dyno'd, my seat of the pants impression is that it has increased the torque from 2K on up. I went with it originally because of the results posted when it was dyno-tested on the Mach 1 with similar mods as mine. That makes me wonder if certain mods do actually cancel out possible benefits if they don't work well with each other? In my case, it seems to be fairly cheap mod with real benefits.

Double O, have you taken the spacer back off to see if the engine runs better without it? How 'bout the vacuum lines? Are they all hooked up? Any splits inthe hoses? I only ask because I was surprised at the number of vacuum hoses running to the back part of the intake, and a couple didn't come off to easy.

Good luck with it.....

 

[HISSMAN]

I think that this is a mod that would work best if the intake was Ported and polished. A nice blower wouldn't hurt either. That is what I want to see. I want to see the gains of a before and after run with someone that is SC'd.

 

[Double"O"]

Vinnie,

All of the hoses were hooked up right and none of them had and cracks in them or anything

I'll see if can scan my dyno sheets to show you guys what happened throught the RPM range
