DONT BY PROFESSIONAL PRODUCTS INTAKES! - Third Generation F-Body Message Boards

customblackbird · 09-12-2009, 07:37 PM

bought my dad a professional products vortec crosswind intake (carb, vortec bolt pattern) for christmas. as well as there vortec high performance intake gaskets. we've both looked at the intake since then and it didnt seem all that bad besides some bad finishes on the surface the ports didnt look that bad etc, (intake comes in sealed plastic bag that isnt perfectly see through)

Now that i have no idea where the receipt is i decided to look at the intake, i took the vortec gaskets out and placed them over the intake ports and WTFFFF! the intakes almost a 1/4" off. I kno this bc my dad also has the modified vortec heads from scoggin dickey. the gaskets fit the heads perfectly but when i hold them up to the intake aligning the bolt holes the intake ports are off by 1/4"!!! Further looking at intake i saw some pretty bad casting flaws in the inside below the carb attachment. bad Pitting etc. not to mention the outside of the intake has wat looks like to be huge grinding marks(like they tried to clean something off the surface that was about 2" in DIA).

i just dont understand how the ports could be that far off, i bolted the intake to the head and the ports really are a 1/4" off. i took some pics. I have used there products before, i have there 58mm TB on my HSR (great peice) and ive used 2 of there balancers (both are nice) i guess they just suck on intakes. i will never buy there intakes again.

pics.
pic 1 is how far off the ports are when the bolt holes are aligned (dnt mind the etch i made)

pic 2 is how far off the bolt holes are when the intake ports are aligned

pic 3 is the pitting below the carb

i have the hurrican intake. mine is great. My ports were a little shorter like yours but i matched/ported them to my heads anyway. I ran this intake a couple times with no problems. I have yet to see the crosswind though.

the ports arent exactly shorter... but they were off by that much... which means now i have a 1/4" lip on the other side that protrudes into the intake runner which means now theres a 1/4" wall to distrupt airflow.

i spent and hour and port matched this as well but theres nothing i can do about the wall on the opposite side

I had the same problem. It was a hunk of ****.

Wow, maybe they had a batch of core shifted manifolds ran. That sucks man. Good luck.

You could weld up or easier epoxy the other side to fill in the open area. Sorry you're having such bad luck with that intake. I never buy chinese stuff, and certainly not proform and this is why.

Yeah close personal friend of mine works for Pro Products. Made in China says it all.

All of the airflow is at the top of the runner, bot the bottom. It looks from the picture that the runner is shorter on the bottom, which wouldn't matter because their is no airflow there.
