I am pissed i bought a performance products intake manifold from 909 Raceparts on ebay. I recived it today and am very unhappy. talk about a junk manifold. this thing is pretty much useless without extensive porting. here are some pictures Im sure this has something to do with the quality

.

"MADE IN CHINA"

That about sums it up.Some things used to be made in Hong Kong or Taiwan and the quality was marginal, but nowadays every ****ing thing is made in China and the quality is dogsh1t! I'd throw the thing back through the window and demand a refund.


Note to self:I must calm down when a fellow gearhead gets done over.

Well at least 909 RaceParts and Professtional products have good customer service, at least they are going to refund my money. I hope all others stay away from this junk. I have learned a valuable lesson today, You get what you pay for.

EDELBROCK!!!

GO WITH BIG E!!!

Send it back to friggin China...............

oh hell yeah im thinking polished air-gap

You did buy this on Ebay though.

With a grain of salt, many ebay sellers aquire factory 2nds, then sell them as 'new' on ebay.

They can look like they are underselling reputible businesses, but in some cases the quality of the product might not be as good as you would expect.

I am not familiar with this line of manifolds myself, but I thought I would mention this, since this manifold has some ok reviews in the other thread

Maby i am picky unlike some other people, but either way the pictures tell the story. I just hope i get my money back soon.

I run into this problem ALOT! Nearly all sand casted parts will have "gas" in them. Gas basically is air pockets traped in the alloy when it cured. Theres no way to fix this problem in any part, other than melting it back down and attempting a recast. Usually when you sand it just gets worse and worse.

I just polished an intake similar to the one in your pics. It was a heck of alot better but it too had a few small spots of gas as well.

damn dude.


mine doesnt look nearly as bad as that.... have you emailed the guy and talked about a exchange or anything?!?

I wish the picture on the intake ports came out you thing the above view was bad. I e-mailed them first and then started to get pissed i called professtional products and asked for their # threw them. I called and the guy answered "mustang depot" and i found out they were also 909 raceparts or whatever. He didnt sound to happy i was returning the product and wanted my $ back. Im not going to exhange, i think i will stick w/ parts made in america.

i personally dont see any problems with that manifold. it looks like every other one i have seen before. i have seen most with casting "bumps" all over. can someone point out to me what exactly is wrong with the intake in this thread?

Theres a difference in casting slag and casting bumps. What you see in those pics are a very low overall quality casting, surface has lots of gas in it and the ports have some horrendous pitting to them. It could have been a poorly made core that would cause that or the foundry had the aluminum way to hot when it was poured.

does that really hinder performance for something so little?

By no means is the following to demean, or reduce your review of this product. Without a doubt this product is no weiand, holley, or edelbrock. It is a intake manifold which has been available and used by circle track guys since before they were ever sold on ebay. For years "Speedway" in Nebraska sold them in thier giant catalog along with many other products that help make claimer motor racing famous.

I have no doubt that thing would flow closely to a victor jr on a flow bench. I don't say this to prop up that shoddy intake or to put down edelbrock. I say it because the intake is not as critical at our levels or in this size of runner possesed by both intakes. when talking about single plane straight shot short runner types. Now it is likely it will have more turbulence that is a given. But I think it would be acceptable. If not you could work it out your self.

For my example I will use the Haltech/Force/Holley intake. it has huge protrusions cast into each runner for the injector instead of "added" raised ones like on all of the other manifolds (including the stock tpi). even with this huge protrusion the intake reportedly still flows 300 cfm. thats within a few CFM of the victor. I got rid of mine on principal alone. If that is what you are doing here then fine. But my AFR 195 heads only flow like 268 cfm.

Haltech/Force/Holley intake

Haltech/Force/Holley intake
If you look closely you will not see a raised "boss" for the injectors. Instead if you look closely you will see they are machined deep into the runner where they should have "broken through". The reason they don't is there is a huge lump of aluminum on the inside of the top of the runner.

I have no doubt one of THESE <--(link) professional products intakes would be very complimentary to a L31 head if that is what you are using. It would definitely outflow them regarless of flash and roughness. I held one at the super chevy show from a vendor there and almost bought it. I would like to try building one of these home built EFI setups and think that this cheap manifold would make a nice cheap sacrificial lamb. But bear in mind when you purchase you are getting what you pay for. KillerRS thank you for your review.

whats getting me is this... look at the inside of the runner... you can see how there were gas pockets.

theres a large chance that his manifold is porous... i dont mind a lil flash or roughness around the edges... they are cheap.


but to have it cast wrong.... heh..:lala:

I'm glad I didn't order one of their intakes....I was about to and then come across a deal on the Holley intake I bought.
They're not supposed to be sand cast, they're supposed to be cast in a steel die, or at least that's what their ad says.

Get used to inferior quality guys....as the blue collar class is stamped out and we are groomed into a consumer nation and build an economy of "service industry", you'll start seeing even more made in china, mexico, etc. And to think I used to bitch about Japan....at least they're craftsmen!

And ominous_87 you have a pm.

I bought one of the big single plane pro product intakes from a machine shop in my home town it is like a super victor my machinist and I are good friends and he has told me that this intake will actually outflow the super victor not by much but it does I am more than happy with mine

Ill tell you thow even the big companys like edelbrock can suck sometimes i had an air gap on my 355 when i first put it in but didnt have room with the stock hood so i bought a cheapie edelbrock performer and it leaks and the alluminum is now ugly unlike the polished air gap so ya you get what you pay for more money usaully better product once you find somethin that waorks well keep it

I'll stick with parts made in the USA unless I have no other choice. I prefer quality over price and you should too. Since you only pay for it once if it's good stuff. If you buy crap you'll be paying for it a LLLLLONG Time!

Stick with genuine American parts.

Hmmmm.....interesting. I have thier "Crosswind" intake, and I have no complaints, especially for the price.

I've had my carb off before, and the casting looked fine. Now, granted - the outside looked rougher than what you get with an Edelbrock or Weiand intake. Which I've had on other engines.

Overall, I'm happy with mine. The rough surfaces inside the runners are no problem. There's a reason you don't polish intake runners. The rough surfaces actually help atomize the fuel as the A/F mix passes through. So even the pits in the casting are'nt hurting anything. Port match, and their fine.

But I'll also admit, mine didn't look that rough......

I've got the crosswind too and I don't have any problems with the casting. It is a little rougher than usual like everyone has all ready said, but that is about it. The only thing I wasn't really happy with is the center bolts that hold the intake down. They come oval so if you have vortec heads, you can use the adapters they give you and it will work fine. But if you have regular heads, they don't give you a filler or anything, so you end up with these big elongated holes. So unless you have big washers to cover the holes you are kind of out of luck. Just my experience.
