Question about the Weiand intake...
So, is it true? I need to know because I might be purchasing one.
Thanks!
The volume of air is so great that the air really doesn't have much time to collect heat. On a 500 hp motor you *might* lose 3 hp.
I've got the polished version and the price has been dropped from $8xx to $5xx. All the factory stuff bolts up perfectly. Plus I felt a little boost in low rpm torque and same performance up top after replacing my LS6 intake for the Weiand. You will have to make a blockoff plate for the egr if you have an '01-'02 car. Mine is made of 1/8" aluminum and one bolt hole for the hold down. It took me 1 hour to make the plate from scrap metal using a Dremel cut-off wheel and then I polished it to match. I would do it again in a heartbeat. Here's some photos of my intake and a closeup showing the egr blockoff:

Or the LS6 is better?
IMO the LS6 is the best for $/hp. But suprisingly it only really outperforms the LS1 at high rpms (~5000+rpm) so if you don't drive the car hard you may see little real world gain with any of the alternative intakes.
The Fast 90/90 setup always appears appealing but for me it's just too expensive. The route I'd go is TPIS, they offer an oval 90mm TB and a modified LS6 intake manifold with a 90mm opening. In tests this performs very similar to a FAST 90/90 setup but for less money.
Either that or say sod it and save for a turbo.
A stock motor with only a catback, tune and a turbo (TTI, GMR) should easily see 400-480rwhp on a Mustang dyno.
So there would be no need spending money on headers, Y pipe, pulleys, lid, intake manfold, TB, filters, cam, heads.

Not sure where you're reading your info at but it's comparable to the LS6 intake.
And I've seen similar things before also.
Have you got any info showing it matching an LS6 intake?

I'm talking power gains. As far as my "info", look at dyno numbers from people on here...look what people said that actually OWN the intake...not far off the LS6 #'s. I never said it "matched" the LS6...I said it was COMPARABLE. Plus you're going to trust an article by a company that has it's own product in there?
Also they compared the intake to a "modified" LS6 intake.
No, seriuosly you asked "is it worth the $$$"
I replied that apart from looks I don't think it is and I also supplied links to a test carried out by a magazine not a manufacturer.
You don't have to beleive them, but hay don't shoot the messenger. As for people who actually own them, well I've never made a study but I can say I've never seen anyone claiming they make more power using them when I have seen on more than one occasion people saying they noticed no gain over a LS1 intake and after they swapped to a LS6 from the Weiand they did pick up power.
Take it for what it's worth - information.
The choice is yours to make and quite frankly doesn't affect me at all because I will evidently not be driving your car around will I. So what gain would I achieve by getting you to purchase either setup.
Oh BTW - if that test was so biased why where 80%+ of the products tested NOT from TPIS and how come their setup didn't beat the likes of the Fast setup if it was such a one sided comparison?
You show me where someone swapped a Weiand intake and DIDN'T make more power than the LS1 intake. The fact is there is no one out there unless the unplugged one of their spark plug wires.

I'm sure you can find them if you're interested, although SEARCH is not working at it's best so it does make it difficult.
But like I said it makes no odds to me what setup you go for, I was just providing info (plus a link) to allow you and others to make up their own mind. I have no interest or time in researching and searching this forum just to prove this point but the info is out there if you want to look yourself.
However if you do go for the Weiand I would be very interested in your results with SOTP & track, as I am constantly looking for new info and comprisons as this is how we gain knowledge and learn.
So please keep us posted with what you do (and pics
)Where you thinking of getting the polished variant?
I'm not sure when I'm getting it, I might hold off for a little, I might go another route(not intake wise, just mod wise).
