Has nothing to do with the DP. It will be likely to crack - it happens all the time. You didn't know that all USDM Evos had twin-scroll turbos or that all manifolds fit each year, but you are arguing about the fact that it will be likely to crack? Not wise...

You had already been given the answer to the question. I gave additional info in case you were not aware. I hate to see people buy things without having all the facts, because they end up regretting it.

 

I haven't had my Evo very long, so I didn't know. I spent my car modding time learning about engines, turbo systems and such in general, so specifics about the Evo are a little foreign.

I wouldn't assume that everyone knows the differences between an AWP, AWW or AWD 1.8l Volkswagen motors, and I wouldn't try to discredit them for not knowing.

I'm sure that anything thats bolted to a car, heated up, then put under stress could possibly crack. I also know that if this product is poorly made and/or put under excess stress it will be more likely to crack.

It has been my observation that alot of aftermarket downpipes for the Evo do not have a flex section, and would therefore put extra stress on the components attached to said downpipe AND the motor (which, of course, will try to move independently from the exhaust components). The flex area in the downpipe is there to allow components past it to move independently from those before it. This effectively reduces stress on the manifold that can now more easily move simultaneously with the motor.

I think it has a little to do with the downpipe.

 

Warr, is there any tests that show gains from the ported manifold (isolated)?
I have never seen anyone test it against the stock item.

 

And you think that is some kind of excuse? How dare you come on this forum and ask a question!

 

Yes, David Buschur did all the testing with dyno proof. There's a huge thread showing all the gains (or lack thereof). The winner was the stock ported manifold and Ebay SS o2 housing. The only thing that beat out the stock manifold was the Full RAce manifold, and it made 4 more whp without losing torque, but it costs a ton.

OP, fine, suit yourself. YOu think you have it all figured out already, but yet you didn't know even the basics. If you think the DP is the whole reason that the manifold will crack or not, then be my guest...get what you want and ignore years of experience and testing.

 

Kinda what I was thinking ...

Ya Warr ... I've got it all figured out. That's why I'm here asking questions ... I guess I just wanted you to come in here so we could debate.

As I mentioned in the previous post, I know that anything that gets hot and is under stress has the potential to crack. It is common sense. I guess that when I make a post here about my tubular manifold cracking, you can hop in and say "I told you so." If that happens, I'll agree and probably say that I should've just listened to you in the first place.

I'm honestly sorry that I started a debate, but I was slightly offended when you assumed I had never seen the Megan manifold on a car and that I was basically clueless. It was quite immature of me.

I'll most likely be getting the manifold. If it cracks, so be it. I will have learned my lesson. However, I haven't stumbled across too many "My Megan manifold cracked" threads. It seems that many more members have had no problems.

You have informed me that my descision is an incorrect one if I'm looking for the most power from the car, and that there have been problems in the past with these manifolds. Thank you. That is useful information and I should have taken it as such from the beginning.

 

If you're a baller get the full race manifold. If you're on a budget and want to be stealth about it just port the stocker.

 

I read that thread. It has good info but it does not compare the ported manifold to the stock one.

The cars that I know from the shop with ss manifolds and intakes make slightly more power than me on the same dyno and we all have the same mapper... I didnt go that route as its a toss if it will crack or not. My friends hks cracked before but the other with JIC is still running strong

 

I wish I was a baller ...



...


I wish I was a little bit taller ... I wish I had a girl who looked good I would call her. I wish I had a rabbit in a hat (something something) ...

 

Why do you act like such a jerk to people on this forum?

TouringBubble, "Drifto" saw gains using a custom fabricated header. I believe it was in the 15hp@wheel difference over the stock manifold.

 

LOL...that song is great.

 

I think that Warr has his opinions and thats great, but the condescending tone that he takes in nearly every post just makes people want to do the opposite of what he says. And when he has a piece of buschur's reputation in his hands, you'd think he would learn to be a little nice. I guess some people are just wired different.

He seems to hate on everyone that doesn't buy parts for 100% FUNCTION ONLY. I had told him about buying a Greddy Ti used for 600 bucks and he flamed me saying that his whole exhaust new was 600 bucks for TBE and called me a "sucker". But see thats the thing Warr, not everyone is scraping for every dollar. Some people want performance and looks at the same time. I'm not saying that the megan manifold will make power, because I have no experience with it, but I dont see why you have to hate on people just because they spent more money on something than you.

I mean for example do you buy shoes from Payless? I mean they do the job right? Pure function as long as they are comfortable??? Gimme a break dude, thats fine to try and advertise products and companies that you are sponsored by, but that doesnt mean you have to hate on everyone that has different thinking than you.

If you really cared that much about hp/$ then you'd make everything yourself. You'd have done a custom exhaust not bought off the shelf. But you didn't. Makes people kinda wonder if you take this tone with everyone in real life.

 

+1 Thanks.

That's a pretty big gain. Was that with stock turbo as well? I was hoping for something like 5-8 WHP over most of the curve, and a slightly faster spool.

 

Don't mind Warrtalon...in his mind if you don't mod your car exactly how he sees fit, then you are wrong.

Go with what ya like, do the research and make your own decisions. The LICP from AMS will indeed bolt up to the IX's and is stated on their website. If you want to maintain good looks under the hood I recommend either Classic Coatings of Jet Hot and give that manifold a little bling. My AMS tube-manifold was coated by Classic and even though it's dulled out a bit there are no other colors showing up...

 

Can you share one example of a cracked Full Race manifold for us? You can be an opinionated jack a$$ all you want but don't spout off pure BS. There are many vendors that make great products whether their name is on the side of your car or not. FR makes a great product that is expensive and time consuming to make and it cost reflects that. It isn't for everyone but that doesn't make it a bad choice.

Yeah, I own a FR and had a ported stock manifold before that. I just never told anyone not to use the stock manifold or to waste my valuable time making me read about them porting it...
