the manifold from hell begins

[themadscientist]

I think i watched too much Wile-E-Coyote as a kid. In retrospect most of what I do has that wacky design charachteristic. I don't use Acme products though so I should be ok.

around here we've been making our own turbo manifolds forever using weld ELs, mig(fluxcore) or stick.For the flanges we simply shave them from whatever stock manifold, turbo or non. I dunno anyone who purchased flanges tbh.Never any of these 'cracking' problems so many seem to have.Certainly not 'pretty' like a stainless header.... but neither does it need to be since its hidden under a heatshield (preference) anyway.Should it work ? Probably not, but I ain't complaining or changing until it stops

[ch187]

it would also be wise to have the pipes back-gassed while whoever is welding it welds it. welds are some 65% stronger. please? for me?

[Myetball]

Just to clarify, MIG=Metal Inert Gas. Solid wire with gas shielding.

Flux=flux core wire with no gas. (should be avoided except for the most basic of jobs)

Many machines are capable of doing both MIG and Flux welding, just have to switch polarity depending on which you're using....and switch wire.

I 100% agree. Any compitenet welder working with pipe/tube will backfill the tubing/pipe with argon/nitrogen/co2/whatever the material requires.

The back side of the weld will oxidize and become very porus unless the innerspace (good movie ) is purged with the approperiate innert gas.

[float_6969]

Doesn't argon pretty much cover anything you'd weld? I'm not a big Nitrogen CO2 fan. I wasn't aware that you really couldn't use argon on anything.

[ch187]

yep. at least i use argon for everything. mig and tig. miller recommends it for all types.

oh my

looks like i decided to drop back into the ca-forum at the right time.

twin 18g's?! have fun!

[MeanGreenS13]

mr madatnico you have mail, please respond asap. thanks

[iliketocrash]

only reason for this is the "wow" factor. Like adding a throttle body to the other end of your intake or wiring in 4 more spark plugs etc.

you may find manifold pictures of this tt 4cyl mitsu setuphttp://www.doitbig.org/coltboostin/pics/4GX7/done/Two ebay $150 T3 turbos hit 560hp atw breathing thru a $30 stock junkyard hyundai(DSM) head. 24psi @4800rpm he says, 2.4L.

Just one 18g/td05 in a 7cm exhaust housing would make a responsive killer street ca18, with impressive high boost capabilities to boot.Obviously not what you're after here tho.

i actually know the owner in person. real nice guy and i can verify that the rx7is quite the beast. although i have to say that the colt he had before it was definetly a rocket as well. he dynoed about 708hp at the wheels in the colt on just the 2ltr mitsu turbo motor.but it was wrecked and he moved onto the 7.

[dash]

yeah, colt was nutz. http://videos.streetfire.net/s...1.htmInteresting projects. Dunno the guy. Many chasis frames, suspension parts, roll cages, etc. fabricated without back gas.... and these are stuctural components.Obviously wont' see the extreme temperature swings of a turbo manifold, but the weld el manifolds certainly get the job done for lots of us d.i.y. ers. If I asked a competent welder if it would work, he'd probaly say no.I'd just smile and walk off

i saw this car at the dsm shootout. that "header" he made was crazy... a lot of jimmy-rigging going on there. interesting project for sure.

[NUT-CSE]

Im diggin what your doin here, im always runing different projects thru my head aswell. I planed a twin turbo setup but i planned to use a setup like this in the pic. Where i have a smaller turbo feeding a bigger turbo.



Let me know what you think of this setup?

[ch187]

[themadscientist]

I thought about that but the added complexity was not desirable. I also had these turbos laying around. I would never go out and buy a set of turbos for something as silly as this. I am pretty pissed that according to the pic someone has already done it; it takes most of the fun out of it for me.

Isnt it better to see someone who was crazy enuff to attempt it and has it working already? I cant find any specs on that setup in regards to power and so on but i know its from Sweden or Norway. Looks you get the best of both worlds with the setup, no lag with big big top end!

[themadscientist]

no. I like to be original and I now see that I am not. Oh well

[ch187]

i have a better idea. you could run a sequential setup like rx7s and supras. find a butterfly out of one and setup it up to run off your standalone. like how you get secondary butterflies to work with standalone. same concept. i think you would have less lag problems and would be original and would be more baller. . just an idea..i know it sucks.

[themadscientist]

My original plan was to have #1 and #4 go into one turbo and for #2 and #4 to go into another larger turbo along with the outlet of the first turbo. The piping would have been rediculously complex and I decided to just go parallel and keep it simple.

[float_6969]

I've got it. Put a T66 on it, and use nitrous. ONLY, don't run the nitrous through the motor, inject it directly into the collector on the turbo mani!

Now THAT would be different!

We do it all the time on diesels...

BTW, Joe's "diesel from hell" dyno'd out at 768whp and 1500+++ ft lbs the other day.

Lots of fuel and some water/meth.

Killjoy...

[r34 gtr]

You're the killjoy, baby.

[ca240sxcoupe]

sorry to post at the end but that doesnt look wankel in that rx7........so what the hell is it????

[themadscientist]

looks like a 3SGTE

[ca240sxcoupe]

what a waste of a good rx7......rotary engines are amazing.....

[float_6969]

Until you own one and have to pay to maintain it.

Not saying they're crap, just high maintenance.

[Bwana]

Ryan, is there a good reason you're not on aim right now?

[float_6969]

No

[DeXteR]

and putting a bastardized, twin turboed 4g63/64 engine is more reliable and less expensive?



i would have liked to talk to the guy about it, but everytime he was in the pits he was working on something in the engine bay.
