Intake comparison - just knock offs??

[GUGS102]

I am in the market for a single plane intake. During my research I keep seeing the Porfessional Products manifolds and am curious if any one has run one, more specifically run one back to back against a "very similar" design from a reputable company on a motor or flow bench, dyno etc.
I know you get what you pay for and I've paid enough so I thought maybe I can get by with a different approach this time. Let me know your experiences and perhaps we can discuss the details.

Just seems as though they are really close. I called the company and they said "well you know there are only so many ways to make a single plane intake..."
I asked if they did a 3D scan and re-engineer the parts and their answer was "no" So with all the aviable info and choices, what is a guy to do??
19' hallett 1800lbs (weighed it last week) 489 BBC solid roller 246 .622 single pattern, 9:1 and a 950 HP DP,air gap manifold, no spacer. Thru transom rewarders. Currently pulling a worn out pump to 5400 at 75 on radar, with the water breaking just behind the dash...(don't worry, pump and set up are next)

GOOD QUESTION, P,PRODUCTS MAKES SOME NICE LOOKIN INTAKES,THEIR POLISHED INTAKES COST WHAT A SATIN ONE WILL FROM EDELBROCK. :idea:

[396_WAYS_TO_SPIT]

I was wondering the same thing...

[superdave013]

ask this question in the gear heads fourm so Cstrub will see it. He'll know the scoop in those intakes and give ya the straight up answer.

[YeLLowBoaT]

I remember reading in some car mag that they had drasticly diffrent CC and flow rates for each runner. Then again It might have been a Diffrent knock off company....

[GUGS102]

Good info,
I do know they say they use a permanent mold rather than a sand cast which depending on how good the tooling is should have less descrepancies in manufacturing. I'll also post in GH and see if we can get some assistance.
Thanks,

Ran a e-vic jr. on pump gas 540 727hp with no mods and an 850 mightymarine
Ran pro products with same combo but different engine, same dyno, 730hp
Port match to AFR as cast was worse than e-vic,spent about an hour and a half on it to get it balls. Very happy with the results
Pro products man+port match = Box stock e-Vic jr. :boxed:

If you havnt noticed I do alot of comparos of bolt ons. Keep em com'n

[GUGS102]

Machine head,
Thanks for the info. Sort of what I was wondering for the cost savings and a hour or two porting, to me worth it. I still think the dart will out run it even ported, but the dart is about twice for satin what the PP is polished.
Thanks,

IF YA BUY ONE GUGS LET US ALL KNOW WHAT YOU FOUND AND THE PERFORMANCE.I'VE BEEN THINKING ABOUT BUILDING A LITE LAY-UP TUNNEL WITH A SMALL BLOCK.THEY HAVE A NICE POLISHED VORTEC HEAD MANIFOLD THAT'S ONLY @120.00.I WANT TO BUILD A 500HP ON THE BOTTLE MOTOR AND DON'T WANT TO SINK A BUTT LOAD INTO IT IN CASE IT SCATTERS! :idea:

P Products Big GM intake is the exact same as the Hardin Marine single plane intake.

[sleekcrafter]

ST, you think??? Maybe it's Hardin selling Performance Products intakes for lots of extra coin! :crossx:
Sleek

From what I have been told the Hardin Marine intake says Hardin Marine on it, but I have not bought one just to see. That would be CP Performance selling the Hardin intake and any other product with the Hardin name on it.

I've heard they are good performers at a fraction of the price of Edelbrock. The early ones had some fitment problems as I recall but that was many years ago. I've looked at them in detail at SEMA and they are looking really like good quality stuff. The co. is owned by Jim Davis, former lead guy at B&M for years. I've met him a few time seems like a straight shooter no bs kinda guy. I wouldn't hesitate to use one on my own engine. Their polishing costs as I remember are hard to beat too.
The above is all I can offer. Never have used one personally or seen a side by side dyno comp. vs similar Edelbrock.

I have no idea about the true origins of this "pro" company but from a tooling aspect don't fall for it. If it's "loads" cheaper, sucks in performance comparo's and looks very well the same as your favorite big name intake beware. Most likely it's one of many cheap look a likes. It's very easy to stick a manifold in front of a BS tooling crew and accomplish something that looks like the spenso stuff. Proofs in the puddin' though. Don't ignore the dyno reports. If you've ever looked at the un finessed products from this company and compared to the real thing you'll see the crap effort at copy cat work.
Just my observation. I saw this company's crap at PRI a while back and had to laugh.

[Rexone]

They are from China (the cheaper factor) but from what I've seen they are a far cry from crap. They look really good. And Professional Products has been around for many years. Usually crap can't claim that.
But like I said I have seen no dyno reports on them in comparison to Edelbrock.

I hate to say it, but I'm still waiting for someone to knock off these valve covers.

Ya... At the end of the day it's in the eye of the beholder. I wasn't very impressed from the tooling stand point. They are look a like which is the real issue. Once an individual begins to "work" something like this the original engineering work of the original probably goes out the door but the castings are drasticly different in quality and intent from my eye.

[TIMINATOR]

A blower intake is a single plane....... TIMINATOR

[MACHINEHEAD]

Post #7, Im convinced. The casting that I got was a little looser
(more texture) than anybody else. If your that worried about looks
have it polished in house, dont have a local do it because he'll charge extra for prep! These will definately go on all my 540 engine packages, pollished of course.

[Tim_T]

Ive got professional products single plane on my bbc and i havent had any problems at all. its a nice piece in my opinion. And for $200 polished you cant beat it. Just my .02
