ive never had a problem with the dnp manifold and neither has anyone that I know. Do you know of anyone that have cracked dnp manifolds?? The reason why im asking is because im making well over 600awhp with over 30psi on this manifold and hasnt showed 1 sign of cracking.
Yes, the cheaper tubular manifolds, specifically the DNP, are known to crack on Evos, and they have already been tested to not make as much power as a ported stocker. You don't seem to want to listen, so I don't think I'll bother trying to help anymore.
warrtalon, im sorry you and I didnt get off on the right foot and i hope we are past that. But, im the type of person that likes to see proof. I dont just listen to 1 persons advice especially about cars. Because I dont know you, or anyone else on this site very well, i would like to hear others peoples views and thoughts, and actual proof that the dnp manifold cracks. And also i would like to read about the test or article that says they dont make any more power than stock ported manifolds. How do i know that ur not some idiot that doesnt know too much about evos??? Im a new member... so unless you give me answers and information that proves what you say, im going to second guess you....hey whos knows... maybe someday i will start asking questions saying, "warrtalon, what should I do?"
I am with you on that one. I always demand prof when people make claims. For example, I purchased an ssautochrome exhaust manifold for my 03 EVO back in the day. Everyone told me it would not make any more power than a ported stocker, and that it would crack. This was also back when people said you couldn't make over 400 wheel HP on the 16G. I was making over 400 wheel HP on the 16G and never had a crack in my manifold in over a year of use. Will everyone have the same results I did? Nope. Did anyone claiming my manifold would crack ever provide a link to a thread related to a manifold failure? Nope.
Looks over performance is Warrtalons "button" and when it gets pushed he sort of loses track of everything else in a thread, and can't let it go. Just let his comments slide, he does not own the site or control the content of members posts. We are not hear to brain wash people into doing things one way and only that way. There is always a place for parts that look good as well as functioning well as long as you realize that they will probably cost more and are willing to pay that extra cost. You obviously have the means to reach that goal
this thred reminds me of nasioc.com
not gonna lie im kinda afraid to ask if you can run a 50/50 bov to reduce the rich condition between shifts but still have the sound.
im not saying i want to im just wondering because on the subaru MAF setup you could run a 50/50 bov and never have any problems.
evo9er im with you and turbolarry on the packages. when i get my evo and when i go to mod it i am going to follow the warrtalon package path but im going to build the package the way i want it with the parts i want.
i like a balance of looks and power but power>looks. ie when i upgrade my ic piping its going to get powdercoated lime green to go with the theme of the car i have planned out.
ok so what are all the problems with VTA besides the richness between shifts/throttle lift.
how much tuning does it take to convert to a MAP setup. i have a plastic VIII bov and i need to replace it and i would like some sound at least. the MR valve is availible and i know that.
dont get mad about what i prefer for my car im just asking a question im not saying im going to do is. ive noticed that about this site people are a lot quicker to get angry about someone wanting something different. subarus are super touchy you probably know that keith since you own one and with a 50/50 bov widebands have shown a very miniscule afr spike and there are no idle problems.
You get that beloved ricer sound when you install the intake. You don't need a VTA BOV in order to achieve it. My 100% recirculating Forge RS is _annoyingly_ loud in conjunction with my Buschur intake @ 26psi. Going VTA throws off the AFRs due to the metered air being expelled, and it leads to idle issues as well as stalling when coming to a stop with the clutch in (vaccuum issue). There is no benefit to using one except for when you have a big turbo with a speed density system (MAP as you mentioned). At that point, the VTA causes no negative effects, and it can hold big boost...assuming we're talking about a purpose-built performance BOV, such as the Tial, not just something created to make sound.
The cost to switch to a speed density system would be the cost of a standalone ECU like AEM EMS (~$2k) or a hybrid setup using the MAFTPRO. It's a LOT of money and trouble just to run VTA...
