DNP Tubular header

[D's GS-T]

Quick question,
I was wondering if the DNP tubular header will work with a FP green, and if so is it worth the money, or are there better options.

 

[Brianawd]

It's "vAry obvious"? That's your proof? srsly? Very obvious based on what?

I give up.

We all know Shearer makes some of the best manifolds out there. Do you think he would design a shit manifold for FP. Come on. Give me a Fu-cking brake. Is the FP better than a tubular manifold? No. Is it better than a 2g or a evo? Yes. look at the collector on the fp manifold and a 2g or a evo. Witch one do you think will flow better. I don't know how much more strait forward some one will have to put this for you. RON SHEARER IS THE DESIGNER OF THE FP CAST MANIFOLD.

What's the big deal that I'm asking for some test numbers? If you choose to believe it's better simply because it's from FP therefore it must be better, then by all means believe what you want. I'm simply asking for back to back tests to prove all these unbased claims that are being stated as if they're proven fact. If it isn't fact, don't state it as such. Say, "IN MY OPINION, the FP is better because it looks so much cooler," not, "Z GUYS!! The FP is so so so so much better than a 2G manifold!! You'll gain like 900hp!!"

 

[Asimmons90GSX]

this isnt something to be proud of



And I highley doubt fp would put anything out there that is junk. They make quality stuff plain and simple.

as far as there manifold goes if you guys are trying to compare it to a ported 2g manifold your crazy... are we like 13 it is vary obvious that it is a much better designed manifold common srsly. And if you read about it you will find it is made of much better material as well. :rollseyes:

And why is that exactly? I'm not "proud" of it anyway. I was just saying I talk to a lot of dsm'ers and our cars kick some ass....sorry. I'm gonna stick with what works. Sorry I don't custom make my own manifolds and don't feel like fabricating everything....which is freakin retarded. Sounds like you guys hear ONE bad thing about a certain part and you automatically assume it's a POS? Please

 

[Asimmons90GSX]

Wow I just bought a DNP.. great

Your fine with that dude....trust me. It'll work great. If something happens to it just send it back and they'll fix it or send you a new one. But it won't anyway so your good.

Here is some info for you. Taken for a dsmlink log. But Would post up more but its like trying to talk to a pro like your self
There was a full second difference between achieving boost with the FP manifold vs the Evo3 (the fp being the faster of course). 5.21 secs to build full boost on the evo3, 4.13 on the FP race. Also, a 22 hp gain.

Sweet. Some actual info. Now we're getting somewhere.

So where exactly is the log and is that 22hp difference on a dyno or is that part of the LAMElink log?

Everyone stay on topic and quit the bi***-fests and flame wars.

Its part of the link log. There is a whole 12 or 14 page thread over on the link board about the performance difference between a FP manifold and evo3. But now you think link is lame. Just so you know there are lots of people on link that have put there cars on the dyno and the link log was with in a few HP of what the dyno read. So againe

Link, please (no pun intended).

I also know people who's numbers were 100+hp off from what the car was actually making so it's kind of a moot point. GTech can be accurate too. It doesn't mean I'd base a comparison test off it.

FYI, I'm not trying to flame. I'm simply attempting to weed out factual statements from fanboi cries.

Information needs to be relayed by rpm, airflow, hp/torque curves, etc. Measuring how 'quickly' something spools isn't the correct way to communicate information. 'seconds to full boost' is irrelevant because there are too many variables that determine these sort of things (i.e., 5.21 seconds from what? full throttle?); I don't understand why everyone is trying to get on CTP's back? The guy is asking for factual data, not a full scale investigation and report.

Do you have dsmlink? If not sorry its a private board

You've been around the DSM community at least as long as I have. You should know that questioning the common knowledge (which isn't actually knowledge at all, just assumptions treated as fact) always gets people up in a riot. After spending a good deal of time in the Honda community and seeing how things are supposed to be looked at I'd like to start sifting through the garbage in this community. Asking for proof before proclaiming everything made by FP (or insert name of other fanboitastic company) to be absolutely the best is a revolutionary idea. So is the idea of trying new things and being open to the fact that just because **** part CAN work doesn't mean **** part wouldn't work better. This community seems to take years to change it's collective mind on even the most obvious things. I remember when people swore that widebands were totally unnecessary for street cars and loggers were all you needed. Or when everyone thought an E16g was the perfect turbo for 350-400whp. Or way back when people though MHI turbos were the best in the world. Hell, there's still people that are lingering on those ideas and they don't even know why aside from the fact that "well, that's what everyone else does and this guy went 7's on a _____ (insert ridiculously inappropriate part)."

DNP manifolds are SSautochrome/XSpower EBay junk. The only difference is that they charge 4x as much for them so everyone thinks they're great. Proper tubular manifolds will not crack, however, 18 gauge steal garbage like the DNP's will most definitely crack in a short period of time. Not to mention the fact that the runners are significantly smaller than the head ports.

If you aren't able to buy a proper tubular, don't buy one at all. It'll only result in headaches.

So if they are junk then why are people making 700+awhp. My be you should so some more reading before posting info like you do.

FYI: "DNP" is a company, not a product. Everyone needs to be specific when referring to which product is known to fail, perform, endure, etc... CTP is referring to the DNP manifold made for Mitsu flanged turbos (DNP26-55). I don't have any experience with those, but not all DNP manifolds are crap. It's important to note exactly which of a company's product that you are referring to in a post - not just the company's name (which commonly misconceives that the entire product line is crap, and in many cases, is untrue).

Personally, I will be ordering a DNP-60 later this week. I have done a great deal of research on this manifold, and it is designed differently and built with different materials than some of their other manifolds. So, it's fair to say that not all DNP products are created equally, thus important to not categorize all of their products as "crap".

Thank you for clarifying. I wasn't aware they had expanded their line.

I just went to their site and checked out the new offerings. It's hard to tell if some of the manifolds are cast schedule piping or thin gauge steel tubing. It appears that the T4 might actually be schedule, so that's an improvement. The welds, however, still look horrendous. The welds on the tubing manifolds are still the same SSAC/XSpower EBay pulse welds that have zero structural integrity and could be made to LOOK good by even a kindergartener, especially after the manifold is polished. The T4 that appears to be made out of schedule (due to the fact that it's made entirely of 90*'s, 45*'s, and straights) has equally terrible welds.

Compare the best I can find from DNP to a proper tubular like a Full Race or SLS:

DNP:

SLS:

Full Race:

Granted the Full Race isn't comparable because it's robotically welded, but it's pretty easy to see the difference. Even the SLS isn't anything to write home about, but it's still worlds better than the DNP. "Yea, but the SLS is more expensive, booo hooo." So what? You get what you pay for.

 

[99gst_racer]

I've seen some beautifully crafted schedule 10 manifolds crack within weeks, and I've seen some OBX manifolds last years, crack-free. A thousand dollar manifold is not necessary for everyone that wants/needs a tubular manifold.

Can the DNP-60 be improved? Probably.
Does that mean it has no value? Nope.

The selection of T4 manifolds under $1000 is slim. Have you noticed?
Whether the welds on the DNP-60 aren't the best or not - it's still holds together. Remember; not everyone needs "the best". Tim Zimmer is putting down 740 whp on his 9 second 2G, and has yet to see a crack on his DNP (as far as I know). And, even if I had a tubular manifold that cracked, it wouldn't be the end of the World. Tig welders are a dime-a-dozen, and time is endless.

What is the debate in this thread, again?

Sup fellas, my name is Jimmy. I have a speed shop with a dynomite eddie current dyno, and a 90 talon tsi awd. I have had personal experiance with the dnp header and LOVE it. I noticed the increase right off the batt. I have had the DNP dsm header on my car for about 3 years and no cracking or problems of any kind. I have been messing with the dsm's for around 8 or 9 years give or take, and have tried alot of products that are out there. So far, DNP is #1 in my book for dsm mitsu header. DSM LINK is #1 in my book for engine management for dsm's. (engine management that makes sence). I have tuned many dsm's in this area, and the DSM LINK has been by far the easiest, and most responsive user friendly ems today still. The DNP header, and DSM LINK played big roles in me breaking a stock 6bolt HP record on sept. 6th 2007. I am still on the stock 6bolt motor. The only non stock internals are HKS cams. Alot of boltons, including my DNP header, flowing exhaust nicely from the motor being controlled by my DSM LINK. Need proof? Call mike at SLOWBOY RACING, or robert at FP. This record was achieved using roberts FP3055. Thanks, Jimmy @ Spooled Motorsports columbia s.c. and CTAinc.

 

[kittay]

^ Do you happen to have before/ after dyno or logs?

 

[jlucas05]

From what i have seen the DNP is a great manifold, i mean how many manifolds do you find that add 40whp to a stock evo, i would say thats pretty impressive, and as far as quality i havent ever heard of any people having them crack, if anyone has actually experianced that then please inform the rest of us...till then no one has proof of any kind of flaws

 

[CTAinc1]

^ Do you happen to have before/ after dyno or logs?

Nah, didnt have the dyno at the time. Felt the difference right off in the seat. My guess would be in the neighborhood 30 or so HP if i had to guess. Havent had much time to do comparison dyno runs, dyno stays too busy for my own car,.

What were the numbers from the last dyno?

 

[Brianawd]

So who ever started this thread. Sorry to F it up. Go with a DNP or a FP manifold. Both are great and you will be happy with what ever one you pick.

 

[99gst_racer]

Knock it off guys, and quit shitting in this thread.
I just deleted 24 off-topic posts.

Stay On Topic!

I will be the first to say that I am not a fan of dnp

but you are obviously in not position to be determin weld quality

first you cannot compare it to the full race because of the machine welding and you stated this.

lets compare it to the weld quality of the sls. You can see that there is many more start/stop points in the sls manifold.. it may be a little harder to see on the dnp manifold but if you look closley you can see that the welds are not cleaned up on the dnp manifold they are simpley polished or chromed or whever they did to them.

Start stops often have porosity in them I know because I perform radiography and ultrasonic testing for a living as well as working on aircraft. I have seen more trapped poristy in start stops than anywhere else also sometimes you will find incomplete penetration... (when making more than one pass) on schedual pipe you tend to find that.

on the dnp manifold I can see some undercut when is permissible to an extent in many welding codes... where as porosity and ip is much more undesirable than uc

WTF do I know.

 

[gsx951]

EBay pulse welds that have zero structural integrity

What makes you say that? Are you a CWI?

 

[gsx951]

Start stops often have porosity...

Post flow for the win.
