Well after a few weeks of playing with collectors and designs i finally found the one i like the best. This manifold is going on a built Ls with a t3/t04e 60 trim with crower cams. I've been getting quite a few pm's asking if I "make a ramhorn" lol. Well here is my final t3 design.






These are the kind of quality welds you can expect from RMS








Next weekend Dunc is bringing his built ls/vtec 60-1 setup to me to get this manifold and my downpipe. He has already made pump gas #'s on the setup now so we will have back to back dyno charts for comparison.

Finally got the customer car over and mounted everything.

Beautiful welds. The collector is a bit wide, what angle is that?

 

not sure what angle but why are you asking that ? like its a negative. I make them wide so i can put good welds all the way around the collector.

 

How does that collector flow compared to a very low angle merge collector such as the other popular ones we see all the time?

looks like some very nice fab work btw!

 

any pics of the collector?

 

Thats def a ? i dont have an answer for. But no other honda manifold making company ports n polishes the collectors standard like i do either. Im def more worried about having good welds all the way around the runners. Im sure it makes 0 difference. Ive made many manifolds with both and i like this much better. Thx guys! Much much more to come.

 

Hey guys here are some pictures of the T4 divided topmount Ryan just finished for my ERL Performance GSR engine.
Very nice welds

sick as always

 

Looks good, but the shape on that divided collector doesn't look like the shape of any divided turbine inlet i've ever seen?

Also, just a note, from my past experience, making the hole in the collector smaller than the i.d. of the wg tube makes a significant impact on a manifold boost creeping. The pic of the first manifold is like that. I know the hole in the wg flange isn't as big as the tube, but i know for a fact that it makes a difference. Neukin's manifolds usually boost creep pretty bad and that's why. I think it creates somewhat of a vacuum on the wg tube as the air passes by the hole and has a dead spot of air between the wg hole in the collector and the i.d. of the wg tube. If that makes any sense. lol

Anyways, welds look great. I'd spend more time making the wg entry smoother than the collector outlet smoother, and if you're going to work the collector outlet, it's pretty important that it matches the turbine inlet shape/size.

 

Thats just how i have them made by my machinist. I do not mess with the external shape of the flange, just port and polish right up to the lip......as for the wg hole ive always made them that way and the last 2 cars i built manifolds for had 0 issues with creep. They held 8 psi and 22psi great. Also, thats the same way we do them at my "daytime" job(cant mention where) but we have cars running 8's all the way up to 12 sec street cars with no complaints. But def understand where you're coming from. I'm building a forward facing header for my street integra. Its getting a 1.01ar gt4202 so that and Boosted Igors car will be the real test. Stay tuned. Thx Tony

You know as well as i do that cars running 8's aren't the ones with creep problems, they're not running "low" boost. The cars with creep problems are T67ish street cars that are running pump gas and need to be able to maintain 8-10psi to redline.

Take this as constructive criticism, i've seen enough of this to know what works and what doesn't. If you think i'm wrong, that's fine.

As far as the T4 inlet flanges, this is what they are supposed to look like

 

Also, i'll save you about $400, don't buy a 4202 with a 1.01, the turbine housing is way too small. I would use an absolute minimum of the 1.15 on a 4202, but i would start with a 1.28.

 

That looks sick man! great work.

 

I wasnt arguing with you at all........thats just the way we do them and we've had 0 complaints. Thats why i said 12 sec street cars. Either way i took it as positive criticism. The barrels are much easier shaped like how i have them made and streamline a lot easier. The cars are making power that speaks for itself. Thx

 

Too late Tony. I already bought it and its going on. This car is strictly for racing bikes and the street so no running 40psi problems lol. I got it for an unbelieveable price too so im not complainin.
Thanks Boostwerks

Take a look at some formula one headers for merge angle.

What, you've never been on ebay??

Looks like the old t04b flange to me, the squared off deal is the newer style, likely to get the biggest A/R and flow as possible while keeping w/in the limits of the defacto t4 flange specs.

I wouldn't go that far. I've ported/polished every collector for every manifold I've ever made.

I can see through the wastegate hole that your collector doesn't even come together in the middle, what's the deal with that?

 

what is the deal with the 3rd degree in the fab forum? a little constructive criticism is great, but it seems that everyone who has ever used a welder has something negative to share about everyone else's work. there doesn't seem to be a whole lot of respect for others on this site... it seems that everyone is trying to cut each other down to try and make themselves look better.

i think the manifold looks fantastic. the welds are great, the polishing is definitely nice and the design will work fine i'm sure. would i put it on my car? absolutely. could i make one just as good? maybe if i had a lot of time, but most likely, no.

 

Good job! But that goes to everyone in this forum too. quality fab work indeed! Just wait til' were all 40-50 year old fabricator/engineers in our own respects (you guys, pro street fwd super-horsepower guys, me, off-road chassis guy) and we will be building stuff that we could hardly fathom now. Keep it up!

Lots and lots of manifold builders and potential manifold builders here. People who know their **** like Tony dont bother to sugar coat it.

so what you are telling me is: just because someone "knows their ****" gives them liscense to be an ******* on the internet? what about with their customers? should they talk down to them when they bring their car in asking a question because they "don't know their ****"?

i just don't think this outlook is acceptable from a business standpoint.

 

If you think someone was being an *******, thats your opinion. I didnt think so, the comments were specifically noted as "constructive criticism" something that is necessary for improvement no matter who you are.

 

If you don't want to hear opinions of your work, keep that **** to yourself. If you can't take constructive criticism then you're not going to get anywhere in life.

I can be and am an ******* sometimes, but i was not in this situation.

how can you say that? Eggum Racing runs a smaller turbine housing and i would say its working just fine.
