Surplize modapuckers lol

This happened today, driving back from work like a normal person. Doesn't happen when I drive like a complete knob, or launch it at 4k.

Anyhow tried off and turning it off and on, that didn't help ?

So headed out to pick up the missus in this shit box, and spanked the limiter, she didn't like it.

Typical German car

Lol yeah but considering it's not even 1.5 years old with 17xxx kms on it, it's a joke!

Modern German cars have a system built into the BMCs and CAN that turn on one of a set of random errors each 18 months for the life of the car to ensure you get rid of it and buy a brand new one just after warranty finishes.

It’s why as cool as I think the golf r is I’d never own one, I’d look at either an sti or the Hyundai i30N

Man my back is sore lol. A fixed bucket seat, semis, several solid suspension arms, rock hard suspension but yeah ended up doing over 450km today. 1.5 tanks of fuel later ?

Good drive with @PLYNX and my mate in his R33.

Okay, admittedly it was pretty fun and first time I've actually stretched the new setup with a lousy tune. Shoots flames, 11:1 afrs, lazy 10 to 12 degrees of timing but it is wanting to light up 255 Nankang AR-1 semi slick tyres. Still need to swap out thr gate spring to a softer spring, running a 4 port solenoid and with a 1bar spring there's very limited resolution, kept spiking and hitting engine protection.

I'm sorry I missed the run.

 

I've spent the day yelling at people and driving back from sunny Singo

 

Glad your beastie got to stretch its legs.

 

What's next for the 33, back in the garage for a spell?

Umm no idea to be honest, I said I'll try go once a month with @PLYNX but knowing my life, even that would be hard to achieve.

 

And here's a dose video and some gate, wallah swear to god I didn't use the photo illegally (didn't talk or text or use social media) lol

What spring are you planning to swap to and what max boost are you chasing? 

0.5 bar and will run up to 2 bar.

At the moment trying to command 1.3 to 1.4bar is very challenging. Every 1% to 2% change in duty cycle is jumping 0.1 to 0.3 bar of boost. By dropping the spring you end up with higher resolution. Just some idiosyncrasies with running a 4 port. Running a 3 port but across both ports on the gate is a simpler solution which allows decent control too, but I wanted to try out a 4 port setup, so here I am lol.

Can't for the life of me think why it would be showing signs of fatigue or damage ;) 

Well it's there to use right? lol.

"The brightest candle burns twice as fast" 

That's why people run boosted engines, to get twice the atmospheric pressure :)

Another solution I've come up with for another car I tune which granted, we've not tested yet - and I don't know how flexible the Halaltech is with settings and available outputs, but we're running 2 MAC valves and running one of them against a fixed PWM look up table to "bring up the base pressure", then use conventional boost control to drive the second one as an effort to retain 3-port style table granularity but give a 4-port style boost range.

Interesting, is that similar to how anti-phasing works? I hear that terminology thrown around a bit however given we aren't in race cars or F1 cars I've never bothered to read further nor investigate further.

4x port was already going into another level for me haha...

    • 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/
