All angles were calculated with a 90c protractor, and home made bevel square and cutting jig. Cut with a Makita drop saw.

Machine Settings:
42amps max current on the foot pedal. 2.4mm 2% Thorated electrode, 1.6mm filler. 5mm stickout, 12mm stickout for the corners. Gas lense with a stubby nozzle. 12Lpm argon flowrate.

Will post up more pics soon

i just came a little.

makes you a cheap date..

Lol yeah. I always find it helps to post settings so others who are attempting the same thing have a bit of knowledge before starting. Cunts do it for me so I will do it for them. Does sound extremely nerd though...

[bogan]

Welds look pretty tidy, must have been fun getting right in those Vs eh!

Is the 90deg between outside headers good for gas flow? or does it not matter so much with a turbo?

number 4 torch tip seems to get most places for me, 35-40 on the floor tends to be a good setting for grunt..

Is the 90deg between outside headers good for gas flow? or does it not matter so much with a turbo?It'll go better with the turbo anyway, but if you google search , "tuned length turbo headers", you're likely to join Akzle in the after glow lounge.

Lol trust me mate its something I need alot more practice at.

Yeah I used and number 6 sized cup for this. Most of the time I use a 8 and hardly ever take it off.

Can you explain what you mean a little bit better? There will be 90 degree bends leading into this collector and they should be fine for the application. 6-7psi. I know crudely made log manifolds are good for up to 350 - 400hp but can be restrictive. If your pressed for space though they do tend to be the best option and you can build them very cheaply with basic tools and knowledge.

I will be welding this up fully before the weekend. I have a cast set of 304 sprigots and some lazer cut flanges to go on. Will tack it up to the bike and make sure it fits then weld the rest

[nzspokes]

Me Hornet will be going to see him soon. :drool:

Yeh good point. Had a mate who did equal length turbo headers on an integra, had like 40 different peices or something fucking ridiculous and weighed upwards of 10kg iirc; 3 or 4mm mild steel as its a bit hard to mig stainless :shit:. Was too convoluted to look good, but I think it made a lot of power, and burnt the paint of his hood cos the clearance was less than ideal... Wish I had got photos of that fucker.

As the gas flows in from the outside it'll flow straight at the wall of the opposite side, get a bit more turbulance than if the headers were pointing more in the same direction. Mind you with a turbo and short headers, there is probably going to be some backflow anyway.

Thank fuck your not a welder by trade.Thats shocking.:bleh:






Nah, looks ok I guess. Nice work.:niceone:

what bogan is getting at is the angle of the collector which is going to create a hell back pressure.. or wave refraction..
admittly on a bike space is certainly limited I have done twice now a four into two into one in a very short space

don't knock logs they do have uses..

[The Reibz]

You will find a well designed collector will actually help draw the gas through the tubes. As gas passes through the collector it helps suck the gas thats on its way through from the next cylinder. There is a real science to equal length headers and im studying up on it at the moment.

Plan on making a set of 4 -1 headers for my FZR1000 next.

You can MIG stainless bro but the wire is expensive. 5kg will cost nearly $100, same with tig wire. Welding aint cheap to get into but I love doing it

Definetly not knocking log manifolds mate. They do save space and you can weld them with a $100 arc welder from bunnings.

Is that welding acceptable?....I have seen better on Urinals.

[Madness]

You're doing well to buy 5kg of 316SST Migwire for a hundie. Because the diameter of Migwire is more critical than TIG filler wire, the filler wire is about 1/3rd the price of Migwire. Different processes used at 'mill.

:msn-wink:

[skippa1]

Yeah....not too sure about the weld finish. Not saying I could do better.....I wouldn't want that finish on my bike and tidying it would be a mission.

Yep definetely right bro. Last time I saw s/s MIG wire I think it was a hundy for a small roll of 0.9 mill 309. Costs me about 25 bucks for 1kg for 1.6mm tig rods. Same with 6061 Ali. Trying to to advance my skill so have started building more shit with my TIG instead of my stick welder.

[The Reibz]

It clearly hasn't been cleaned yet as it is still a work in progress

:killingme:killingmeThats the trouble with having a dribbler eh M to much time to look around,i gotta concentrate on the job in hand myself otherwise the cunt next to me starts complaining about the overspray....

[98tls]

Looks a thing of beauty to me mate and you have the satisfaction of doing it yourself,far better even at this stage than i can do.

[The Reibz]

Cheers pal, and yes it is satisfying. Discolouring in stainless is normal, it cleans up with pickling paste to bright shiny metal. Or just a flap disk, and autosol from supercheap

Hey if you're happy, all power to you man. Sweet job to take on

[The Reibz]

Took on some of the advice from the other day and realised I didn't like the direction the project was taking. Collector looked rushed and I did a test fitup with it this arvo and wasn't happy. The manifold was to long for the large-ish turbo and I would have had clearance issues. Its in the scrap bin now, on the way to a better place.

Spent a few hours in the shed again with the drop saw and the welder and this is what I have currently come up with...

285135

Will tackle the rest of this tomorrow.
Autobend wanted 180 bucks for a lazer cut flange. Told them to fuarrrk offfff and am going to cut my own one out now. Hopefully first try

[macka77]

its a mig weld point an shoot not flash, a tig weld is smaller, smoother an can look trick if done well

[The Reibz]

Did a bit more work today, this is the stage im currently at, camera doesn't really do it justice. I pretty damn happy with the welds.

Also did a quick plate of fluxcore Mig earlier in the week...

[AllanB]

HAve a look at this USA site - they will ship to NZ but that's a few bucks. They have a set of preformed collectors for 4-1 layouts. If you have room the two on two set-up may be better than the layout you are presently proposing in respect to flow.

[The Reibz]

Some nice looking stuff there. Unfortunately it is far to long and will have the turbo dragging on the ground. I want this stuff hand made anyway, adds to the learning experience alot more.

I dont know how well this will work but it looks nice.
285373

Pretty sure this wouldn't fit behind the radiator
285374

The manifold I have been using as a base is the RCC Stage 1 and 2 Kit.
285375

Bear in mind mine is entering into a standard subaru turbo flange which has a 2' single entry. RCC designs theirs for Garrett t28s and the square t3 flange

[The Reibz]

Spent a good couple of hours helping NzSpokes today with his new Trioval Yoshi stubby can. Looks bloody on a 900 Hornet. Hopefully he will be along to post up a photo soon.
Also have a couple of the young ones from the NASS crew over tomorrow to get a GN125 Pipe put on a 125cc Chinese speed machine!!!

Haven't been working much on my own projects but I will start again shortly. Might even sell the Manifold I have made to fund some good pistons and rods. Hopefully someone on trademe will be interested in made to order Busa turbo manifolds.

[nzspokes]

Was an epic day today. Reibz went the extra mile on the Hornet. Great job done.

Sounds like a GP bike with revs on now. :laugh:

Cheers Mate.

[nzspokes]

Photos of me bike, very happy with new pipe.

[The Reibz]

Choice! Looks like it turned out really good. Glad your happy with it!

[TLDV8]

I miss a little shed welding action. :yes:

Did this up for a hornet 250 today. Sounds good. Rode behind him for a bit.
Anyone need anything done? PM me

[nzspokes]

Thats a long Yoshi. But they are begging for a better muffler. He may need a rejet though.

[The Reibz]

Yeah its long but it suits the bike. You should see the inside of it. Its like 3inches. Practically a straight pipe but it muffles it surprisingly well.
Hows your one going? Still holding on there I hope lol

[nzspokes]

Its great, love it. Its the packing that shuts em up. mine is quiet at 100kph even being so short.

[The Reibz]

Been working on some new shit. Won some money at the TAB and funded another 5000l of Argon.
Also been playing around with sketchup.

[bogan]

Neat!

Are you gonna weld up a bonnet scoop with exposed throttle butterflies for that MR2 :innocent:

[The Reibz]

Its my brothers car ay not mine. Runs pretty good but Im way to big to drive it, pedals are to close together and my big feet are clumsy.
Just waiting on the tips now from the states and its good to go. Started it up and took it for a burn last night. Very loud

Less than 70,000km on the clock. Not to bad for a 1988

[unstuck]

Im way to big a cunt to drive it

Fixed that for ya, cunt.:2thumbsup

Fabing up headers again. Been a while since i've done anything with my welder but getting back into it again

[bogan]

Preefab collector looks good, decent price?

You gonna grind the welds back to flat or leave em exposed?

[The Reibz]

Collector was around 60USD from memory and the flange was 100.
I'll be leaving the welds on. Polishing and grinding flush is a waste of time when its going to discolour on the first use. Guy im doing it for is happy with that too.

Looks good already and its only a 1/3 done
