M42/M44 ITB Kit Design

[Rockiii]

Hey Lambertius,

as said via PM in bimmerforums.com...

I absolutely follow this Threads as i'm going to build up my own itb's.
my idea with the 35mm ITBs wasn't that good, so now i'm heading forward to create my own ones.

But there is one simple issue at the moment.

My intake manifold is in my garage, 50km away from me and i'm not willed to go there in the next weeks.

So could anyone please give me an exact measurement of the port face and the bolt distances at the head/intake flange?

Thx in advance!

Hi Guys, just bumping the thread to let you know I'm still alive!

I had a simulation crash when I was trying to do a good animation, but I've been running it again over the weekend to show you what we've decided to go with. Heads up, it isn't perfect, but it really isn't feasible to get it perfect. I would feel confident saying though, that it is a better than typical setup.

The casting is apparently due back from machining mid-December, so I may even receive the kit before Christmas. No promises, but here is hoping!

Those are the dimensions for the port face, good luck! As I said before, 35mm ITBs are far too small though. They will choke the engine, they have a smaller area than the port itself!

This kit will definitely be the go to kit when its done. It will be far better than the Dbilas kit! You won't ever get it perfect, but you actually did more than slap some ITBs on and connect them with a manifold so its already better than the current commercially available options.

Ramas site has lots of good information on it. I am confident he will produce a great product!

The airbox is a nightmare to be honest. Every combination that flows really well is unreasonably difficult to build, or impossible to fit. We have a 'best resort' option at the moment, but I'm still working on designs to see if I can get a really good option under the hood!

Also, on a completely unrelated note, some of you may be aware that I make some car videos with a friend https://www.youtube.com/channel/UCWUP1B1CN0WXN_tALe6RzGg That is my channel there. We only have one camera, sometimes other friends have helped us or we borrow gear, but we don't have much. My mate who does the filming with me has entered a competition to win $10k by making a car insurance commercial http://www.justcarinsurancereeldeal.com.au/view/5482f806edfc18ec40000052 that is his entry.

We have some cars lined up for next year, and we're trying to organise some sponsorship for equipment, but it would really help us out to win the competition as well so we can get some new gear and make some better videos. We'll be making a video on my car once the kit is fitted, so that is one of the episodes due for next year! Anyway, I would appreciate it if you could like his entry and help us win! You enter by liking it on facebook so it is pretty straight forward! Oh, and subscribe to us on youtube!

Are you guys going to 3D print the airbox? 

[Jasonixo]

Great work so far!  I'll be following for my M42 2002 swap & M47 crank upgrade!

lambertius- What power range do you see your setup accommodating?  If my goal is essentially 2/3rds of a Euro S50 motor (200hp), will 42mm breathe enough considering the intake optimizing you are working on?

[lambertius]

Just an FYI - things haven't stopped though it has been quiet!

Things slowed while we were waiting for things to get manufactured, and I've been in the process of relocating from Sydney to Perth. I've got a massive write up for you guys once I get a chance, but it is still a couple of weeks away!

In the meantime, here is a teaser for you guys

Any plans on these reaching the US?

Any plans on these reaching the US?

With the Australian dollar taking a nose dive, it will basically be 50% off after the conversion rate and all you have to do is pay for shipping. http://www.racehead.com.au/ That is the guy who will be selling the kit when it is done!

Sydney to Perth is a big move! Unfortunately there is not much inbetween them east of Melbourne from what I hear.

Hope the move goes well

Any updates?

Any updates?

Yeah, real estate agents in Perth suffer from pretty severe NEVERCALLYOUBACK Syndrome...

And CEVA logistics damaged my girlfriend's car and then refused to pay, even though (I'm not making this up) they documented the damage in their own transport logs...

But I'm pretty sure you mean, with the kit... Well, we've got a lease on the horizon, which means odds are I'll be back in Sydney in 2-3 weeks to finish this up

I've also written a 5 page monstrosity that summarises all the stuff I've learned along the way that has influenced the design (rather than the disorganised ramblings of this thread, where I'm like 'oh! check out this new thing I did!'). I won't post it yet though. I want the dyno results, and to collect some simulation data on specific scenarios to match the dyno. Hopefully I'll have a few suprises for you when I get there!

So yeah, Rama is coming to Sydney in ~2 weeks, so will I and we'll get to work finishing the kit and running it!

Cool, I might be up for one of these when they are ready?

Have we organised a pre-order / group buy yet

Sorry to hear about your moving troubles. That stuff never seems to go smoothly and damage to your stuff is to be expected. Hopefully it all smooths out soon and its not a bother anymore!

Good news about Rama coming to Sydney. Looking forward to any progress you make!

Brief update guys:

I'm back in Sydney and met Rama today. I've seen the kit and it will start getting fitted tomorrow. First thing in the morning I'm heading to a dyno to get a stock setup power run, and then to Rama to get the ITB kit fitted. After the kit is fitted I will get an exhaust fitted as well and then the car will get a tune.

I wanted to go Power Run>Exhaust>Power Run>ITB Kit>Tune but I can't afford it  The tuner I'm going to is overpriced - but they have a hub dyno which is more accurate and more reliable - especially since I will be coming back at a later date for the comparison run. They are also set up to tune the OEM ecu directly which the cheaper dyno places aren't set up to do. So instead of $60 for a power run it is $220! I'll try and negotiate with the guy a bit more tomorrow to see if he will come down to a round number for the whole lot, but I doubt it. So far I've kept costs on my car very low by striking deals that any work performed would be featured in a video for my youtube channel. Brintech and RHD liked the idea and have been helping me out along the way, but I haven't been able to find a dyno to come onboard.

Its a bit of a setback that we won't see the ITB kit run on its own, but we will be able to see an overall result!

Anyway, if someone knows a tuner in Sydney let me know asap otherwise I'm off tomorrow to get the power run and the install started!
