Hey, I think finally made a manifold that really works for our cars. It took a lot of screwing around with. I had to convert to a side mount tb for clearance reasons. I have not dyno'd this think but its def better. I am waiting for a turbo kit now so I expect way better than stock with F/I. All the parts are cnc'd the ports inside the plenum are radiused. It uses the factory injector flange and gaskets. I dremeled the ports smooth after this pic. The paint job sucked but I was in a hurry to try it. a built n/a motor would love this manifold. However it is very labor intensive to build and Im sure that the $1700 price tag will seem rediculous to almost everyone therefore I doubt I will try to sell them.

OMG you made that. Looks amazing, and what material is that?

 
Rep Power: 297

Its aluminium. all runners are equal length just a lil shorter than stock. Plenum size seems a lil bigger than stock. Its hard to get real numbers as far as measurements go with the stock mani so there were a few trial and errors and this one seems like i hit the nail on the head. I am only using a stock size tb, if I went bigger I think it would be even better. I run a small metal fab shop so this is about as professional as you are gunna get.

That is so lovely
nice smooth, decent length runners, smooth ports OMG just nice
after all of that work you have to dyno that thing NA.
Much props for all that hand work. And for the innovative runner design.

Thanks man. Im sure someone on here will try to put it down,hehe. But I know in my heart its all good.

 
Rep Power: 351

put that down hell no! that is the best design i have seen yet for our car. now if it gives power thats up to the dyno. but from what i see looks like it will give a nice gain! much props!!! if you pull good dyno numbers you should try to sell the design to a big name company so they have something to go buy. make your self some nice chump change . and gives us a new intake mani good luck on the dyno hope it pulls good numbers.

Damn dude!! Good job. All you need to do now is dyno it.

 
Rep Power: 297

I will try to take a day off in a couple weeks to go to the dyno but we are jammed with work right now. I think if it tryed to sell the idea they would just steal it cause I cant afford to get it pattented.

That is fawcking Awesome! I wish I could afford to get one for my car. Loos like alot of work. What type of intake are you gonna use since it's side mount? I assume you coud use an intake from like a 99 civic ex or si.

Right now I cut/hacked a Short Ram on there. I could cut a 7th gen CAI to fit but Im not gunna ruin one as I only have a lil bit b4 i get my turbo kit. With the SRI it still seems to have mad mid range torque. It pulls harder almost all the way till red line falls off a bit around 6500 which is still better than stock. Im def gunna bore out the tb now. I know Ill see better gains that way. I have done no tuning as of yet. I left the cam timing in the stock position all a/f mixtures are stock. I have advanced the ignition timing on the emanage 7 degrees, I dont dare to go higher yet, good difference with that. Its amasing how weak the VTEC is with the d17 you can barely hear/feel it. It is there though. Gimme some time to play, Ill have this thing rippin it up in no time. FINALLY ITS DONE!!!!

damn man!! thats awesome. i wish i could build something like that

 
Rep Power: 289

thats crazy!!!
good job

 
Rep Power: 811

You advanced timing 7 degrees! Isn't that a bit much? Glad you're feeling a difference with the new mani. If you want, maxbore.com will do the TB for $100, but I'm sure it's something you'll do yourself. Mad props to you for that IM design. You should be working for a company designing engine parts. I bet yours would work better than anything out there.

That is definitely something to be proud of.
My hat's off to you man.

What type of welder did you use?(i.e. was it MIG, TIG, etc.)

man that is a sexy manifold ur a good at fabin metal awsome job@@@@!!!!!!!!

 
Rep Power: 0

That is hella nice, i wish i had the tools to make something like that!!

 
Rep Power: 297

Most car manufacturers Turn back the timing 3 - 5 degress from optimal performance to compensate for crappy fuel and such. I always use super so it will be fine. Any more without a dyno may be pushing it but I dunno. Of course once the turbo is on I will hafta retard it.

 
Rep Power: 297

Its all tig welded. Its way more precise. We are upgrading our machinery and expanding our shop very shortly so maybe I can cut some costs. I'll see. If someone is near Middleborough, Mass I would build them one for cost of materials and machine work and help them install it just to see what happens on a car with basic bolt-ons. My car has been totally rearanged so much its hard to compare. For my set-up it works awesome but I dont know how it would be as just a bolt-on. My email addy is GJ77Camaro@hotmail.com if ur close by. I will only deal with someone who has a real good understanding of modding cars and someone who is looking forward to benefitting all 7th gen civ owners.

Ok - it looks good. But before you become another DH racing, "awesome" is defined only by how you think it works. Get some concrete proof that it was R&Ded, and that it works, than we'll talk.

 
Rep Power: 297

I would never sell something that wasnt tested and proven. This was my 4th try here. Lots of time and thinking went into this. I worked with various freinds that are great engineers. I started this 4 months after I bought my car brand new so its not something I just slapped together. I have not said much untill now in fear of becoming another kms or dh racing. I did this for my own car, not to make money. If the numbers show positive gains as Im sure they will then maybe I will make a few. Im not trying to be a jerk I just want ya to know where I'm coming from. The manifolds are designed a certain way from the factory, trying to beat honda's engineering is probably impossible. However, the stock manifolds werent designed for max hp/torque they were designed to be environmentally friendly. I would make one for free to try on someones car but it honestly cant afford it right now. I will gladdly take constructive criticism/new ideas to see if there could be anything I have overlooked.

I was wondering how the mani was coated. The more heat you repel, the better. Stock is plastic because it doesn't get hot as fast, and that's where most of the performance comes from. Still, I would definately buy one if you can show that it gives good gains on an NA car. I already have the head port/polished with header, and I'm sending out the TB to get bored. The only thing left is the intake mani basically.

 
Rep Power: 312

Excellent. I can see you did your homework by keeping the runner length close to stock - our wimpy D17s need all the help they can get torque wise, and that is a step in the right direction....

Can't wait to hear more.

 
Rep Power: 297

Right now i just put paint on it. I am looking into having it teflon coated after I dyno it. Someone told me it may flow better that way.

WTG man, looks nice. I know steel prices have trippled, not sure on aluminumnum, but I wouldn't doubt it at all if you see any gains. It may be a few horsepower, but who knows. Im not too far from where you are, so PM me and give me some figures, I don't have any mods on my car right now.

 
Rep Power: 297

Well here's the deal. I went to the dyno tonight. It was 90 degrees and like 95% humidity. The fan at the dyno was broken. I brought up the midrange alot, and gained lots of tourque. 112 hp to the wheels (can get more under better circumstances) and 116 ft/lbs! advanced ignition timing 3 degrees. the car was running rich after 4500 so i cut back some fuel and holy crap. On the highway it just keeps pulling now. The HP gains werent as much as I expected but the torque is so sweet. From 4000 up to 5700 it has gone up drastically from the stock intake manifold, thus producing a bigger power curve. The intake is sooooooo loud. This is gunna go so sweet with the turbo!!!!!!!!! I'm going to the track tomorrow now. Ill let you know how I do. Later everyone.

Nice work, care to share the dyno chart?

 
Rep Power: 297

I only got a laptop with no scanner so I guess I really can't prove it but I give you my word that what I say is the truth. I know thats not much these days but some of us are still honest. Actually im not extremely impressed with the hp gain but its still positive and it just makes the car so much more fun to drive. I am very very happy with the results though and I doubt i will change anything on the design. It works great and I say if it aint broke dont fix it. Also anyone using e manage dont go past 5 degrees on the ignition timing lol it just barely starts detonating when ur lugging it in fourth or fifth.3-4 should be mint though.

 
Rep Power: 286

looks slick, i hope it will gives some nice power gains

 
Rep Power: 811

What model of car do you have? It seems like you got good gain from it. Usually, NA mods like that won't do much. I have the head ported and can't really feel much either. Once you start doing more, it will all work together. www.maxbore.com does throttle body porting for even more airflow.

I have an EX. HP header, Full 2 1/4 exhaust with no cat, e-manage, return FS, no a/c or ps, clutch masters clutch and flywheel. Im curious what these cars put down with a cat and a/c and ps, anyone know? After I tuned it the maniold made the motor sound and feel like an older gen but with more tourque. It felt ok b4 the dyno, now it really rips. Im gunna put another one together and prolly give it to someone on here that can use it just so I can prove to everyone that it works good.
