Thanks for the compliments.

Pulse setting varies depending on what part of the plenum I am welding, as does the wave balance as some parts need more or less pentration than others. I'd say just turn it on and try at a level which you are comfortable at travelling. Certainly helps with consistency.

NYTSKY - I was only speaking to Shaun the other day, he does some seriously good work. Certainly one of the best around and miles ahead of me in weld quality. His manifolds for the Gen 3's have been compared to some of the top names in the states, certainly a very good compliment.

Not sure on the silicon content of 5356. I use 5356 due to its larger resitance to cracking with its high magnesium content and suitablilty to 5xxx series sheet I use..silicon is usually only referred to when discussing 4043 rod.

you are correct of course :( i just hadnt worked with 5 series alloys yet.

i decided to investigate - here a good little guide i found that might be useful to others

interesting fact about the 150F extending heating they mention in regards to the 5356

That's a good find which keeps it nice and simple.

Considering 150F or 65C is not often reached for the extended periods of time these guys would consider "extended", using this filler is not to be seen as a concern for anyone looking at fabricating anything for their projects using 5xxx material.

Just to add some comfort, I have never had a plenum crack due to fatigue, I do have plenty of plenums out there on cars which have been doing the rounds for some 5 or 6 years still going strong. Correct design and welding process will ensure fatigue will not happen when using these materials/filler rods in combination.

Happy welding :D

  • 3 months later...

It has been a while since I updated this thread, so here goes.

Another busy weekend...finsihing those ones from the last weekend and then completing two "Street" version CA18's. One for making it's way to Sweden and the other into a previously Zoom featured 1200 ute....oooh how I miss my old 1200 ute.

I think this weekend has definatley been my best welding weekend ever!! I have gone through a complete large size gas bottle in 5 or 6 days of work.....at nearly $300 a pop, the guage definately moves too fast.

Cheers,

Ariel

Coming up CA18 and ITB SR16VE :domokun:

im working 2 be doing an ITB + rear wheel drive + turbo inlet manifold for a SR20V soon

ill be using BMW M3 throttle body's

plan on cutting of the flange and welding on the SR20V flange str8 onto it then put a plenum camber on the other end of it

I ended up using gti-R throttle bodies.....perfect port spacing no hassles what so ever....just had to drill a couple of holes on the itb's and make the bellmouths to suit. It was for an NA circuit car with limited engine space and runner design due to class regulations.

I actually just sent one off on Monday...they are $1400 + delivery. I would also need the standard runners to do the job.

As for a rating, I'm not really into quoting a max hp, even though they are all flow tested and in the case of the XR6 plenums it will be well in excess of 1000hp, it is more about the benefits they provide and what they do for an engine to perform as efficiently as possible.

Cheers,

Ariel

nice job...did you end up finsihing your engine with one of these heads?

yep

ive got my engine together and its fitted into the car along with the fabrication work

mines a big mix and match of parts

the cylinder head is taken from a X Trail SR20VET

cam shafts are taken from a P12 pimera

exhaust rocker arms are taken from a P11 SR20ve

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
