As for E85, I get it, but its one of the main things that makes the unit useful to me, that's why I asked.

Hot start

Thanks for the videos. That does seem pretty good (ie not much longer then stock)! The M3s definitely seem to crank longer then that.

Btw, I think I've figured out the reason why the M3 videos seem to take longer to crank - E85. Both videos I had watched were running E85. You are running normal gasoline, and thus crank times are normal.

Just wanted to say great job on the build, I remember your other thread asking about building your own kit and everyone said you would never make it, well you showed them! Congrats

He has done a great job.

I don't remember exactly what I said, but I generally don't say a person can't do this, just that most don't follow through with their intentions due to many reasons. As I'm sure he can relate to now, the costs are much higher than people understand, both with time and money.

This is a rare achievement.

bimmerguy, i'm sure you've got receipts for everything somewhere, but just a ballpark estimate, how much money would you say you've spent to get the car to where you are right now? something else worth mentioning, how many hours would you say you've invested between research, building, tuning, etc.?

for the sake of everyone here, keep up the great work and keep pushing the envelope, this platform needs all the help it can get when it comes to knowledge on turbo setups.

My comment wasn't directed towards you, you seem to always give good advice or constructive criticism. It was directed to the people bashing him for even thinking about doing this project because they think they know everything.

Thanks! Yeah those people just have no respect, and In fact, It just helps me continue to go against what they say.

Agreed As you know its costs in time + money from doing your own R & D thats what gets me.

Thats a good question. I've gone through several configurations, I can estimate in parts I'd say around 6k for my configuration. Thats not including my time to fabricate, and the R & D, and trial and error.

Like i mentioned earlier, I did my own route to set out and build a turbo setup cheaper than technique tuning and in the end I DID. In fact, my setup is better. Now If theirs at least some one out there who reads this and is inspired to turbo or even mod their car because of my project, thats pretty cool, and more power to you. I hope to continue to see more individuals turboing their car, as I go to numerous car shows/meets its hard to find those kind of people whom are motivated and driven to do things.

I will continue to share information, but I wont spoon feed (thats where "google it" comes in)

As far as the future for my project I come to a edge of the fence. If I want anymore power, it will cost a decent bit. My ultimate goal is to have a 10 second car, but realistically, i'll be happy when I have enough power that I cant use it fully on the streets, but only a track.. Now I know M3's have gotten there, on some stock parts. I now look at it as whats the least path of resistance, to buildup a non-m to be "I believe" one of the first to reach 10 sec in a non-m (w/non-m motor) in a e46 oooor start out with a m3 and build that up.

I'm doing a great bit of research on which way is really cheaper to go faster. We all can say well the m3 has a LSD, revs higher so bigger turbo can be used, no oil pump exploding etc, but when building a m motor and the aftermarket parts needed, seams to be where it gets interesting.

Here's the thing - most don't have access to the resources or skills to do the fabrication of pieces though. How many hours would you estimate you have in fabrication time of the current setup, and how many hours in tuning (probably 100+ overall if you are like I was with a friend's calibration years ago.)?

What exhaust manifold did you end up using? Edit: Nevermind, I see it was a SPA manifold.

The upside is you have a literally unique car.

Your right Matt. As-far-as hours I truly don't know. If I was to guess I'd say ~ 80 hrs with the fab/install and about 30 hrs getting the CAN bus to talk to the EMS, the tune, then problem solving sporadic idle, running rich all the time, and boost spikes.

SPA manifold is ok, but the WG hole was smaller than 38mm! I liked my TDC manifold (that I'm still selling), better quality cast. Next manifold will be a custom tubular

Yes the car is unique, I love the sound especially, it sounds like a mix of a supra and v8. If I end up going to a S54 motor, I would hope i don't get that notorious raspiness, reminds me of a Honda with a fart can on it.

so today I decided to up the boost. according to my log im at 26PSI (over what my boost gauge can do) and an estimated 539hp. Just need to find a dyno with a good rate!

car gave me chills the first 2-3 pulls. losing traction at 80MPH in 4th gear!

see the video clip

running crappy 91 octane. compression is slightly lower than stock I'd say (10.4:1) since I put in a .04" MLS HG

You are a bit beyond playing with fire. As a reference, we are usually knock limited on an 8.5:1 cr s52 with 93 octane fuel at around 18-19psi on a ~62mm turbo. One single knock event can and will break the ring lands in a stock cast piston.

just like his sig says, "without failure there is no success". this gentleman is an asset to the community and he clearly has no problem with seeing what the limits are on a stock block. i hope he continues to evolve and improve his project so that the rest of the community can finally have some knowledge on how to turbo an e46. this platform is already 14 years old and still barely has any options for FI so any help he can lend is certainly appreciated.

Mike,
Remember I' have very conservative timing so, I have yet to get knock. Now your reference, what is the timing up top like? what is the specs on this engine you talk about? I have taken the tactic of running more boost and less timing As I'm sure you know that would equal less combustion cylinder pressure --> less stress on parts.

If I'm "beyond playing with fire" why can a continually run 20 psi on crappy 91 and high compression? especially as my Daily Driver?

Thanks daemonicus for the support. I'll admit its ballsy to be DD'ing those limits on crappy pump gas, yet alone stock internals. Only the few has taken on the challenge to do FI, most do it for profit to sell it as a "Kit" Even OEM can only get a ballpark of safe tune, therefore every car is best tuned individually as EVERY engine as a slightly different foot print. I personally know a couple people with stock ECUs whom got it "flash tune" that have had multiple issues. It has been challenging to pry information out of others whom know what works and what does not. After obtaining the experience on the non-m, I now see the other side, but refuse to continue history for at least the e46 platform to not share the raw truth.

It would be great if it took off like the tuning software on supras, DSMs and even hondas, but it seams like money is the route of all evil to create a editable software (shark edit never came through). There a a handful of individuals in the US alone who can decipher the BMW DMEs (pacifically e46 versions) so they can tweak the data, yet they chose not to share info; some made a kit, while others saw the profit potential, and made a service to do in-house tuning. that leads to users tweaking out of it. hence a GAP for the true DIY'er to go on a tangent to do a one off, that in it self can be overwhelming and comes to a brick wall then it comes to tuning.

A real help to the community is to take the DME editing knowledge and get programers/developers and make a tuning UI, then sell that to the public. I guaranteed you see more F/I projects, I would respect and support them!

The 500+ hp, is that with the 60lb injectors you mentioned earlier in this thread?

Bobby,

It is, they are at 78% duty cycle with the turbo pushing around 54 lbs a min.
