Here's a couple of teaser pics. I'll bet my buddy Joseph wishes his motor was assembled to this level of precision. Links to hundreds of full resolution pictures below.

















Now there's going to be another 3-4 month delay while we redesign the blower assembly and design our own dry sump. We believe we can design a dry sump that will retain the air conditioning -- something the Dailey dry sump doesn't offer (sold by Turner and VAC). So this will probably take another 3-4 months to get done. We plan to offer the dry sump design for sale through one of the bigger BMW racing companies.

Hey PencilGeek! It's been quite awhile since we've exchanged emails and what not. Great to see some incredible progress with the build!

I am VERY excited to hear more details about the dry sump. Is it safe to say that this will be the CRAZIEST Boosted E92 M3 out there?!

Keep up the great work!

It will be the most powerful built S65 motor :goldcup:

Thanks Alex.

I was ready to give up on the dry sump idea and even told the guys to put the stock pump and pan on the engine. But after we got all of the accessories mounted, the race shop looked it over and is very sure they can design a dry sump that will keep the AC. Even better we "think" we can keep the retail cost to about $5k, instead of the $7k of the Dailey dry sump (that Turner and VAC use). This shop has designed many dry sumps -- maybe a few dozen -- so this isn't the type of thing they will start and find they are over their heads.

I'm just out to do my project the way I want to do it. Will it be the craziest boosted E92 M3 out there? Maybe for a while, but of course that will only last until the next guy comes along and does a turbo. We're pretty sure we will stick this thing on an engine dyno to tune it. That will be another first for a boosted E92 street car. Stay tuned and we'll see what happens.

This is really great news Robert! I know the project has been long in the making, but there is no doubt you and everyone involved are achieving things people could only dream of.

Engine Dyno would be amazing!! No doubt going to be a first for this type of application.

I remember at one point you had the RDSport Headers. Are you back to stock headers or do you plan on doing anything different to address the exhaust side of things?

I have a new set of RD Sport headers. The originals were a preliminary design during the stroker motor development. The new ones remove one set of connectors, making them two-piece instead of three. But they still retain the same basic 4-1 long tube design. They are also 2mm larger tube diameter than the originals.

The exhaust for the engine dyno is mounted in the opposite direction of the header direction. On most engines, this isn't a problem because you can just reverse the direction of the headers by swapping left-to-right. That only works if the head/headers have a bolt pattern that is not uni-directional. Of course, the S65 has a uni-directional bolt pattern on the heads/headers. So that means we can't swap left-to-right without making an adaptor. It's easy enough...just anouther 8 hours of time...that's all.

The racing clutch I'm using was designed with a standard flywheel bolt pattern. We checked this for the dyno and we can see that the clutch bolt pattern will bolt right up to the dyno without having to make an adaptor plate. So that's not a problem.

The biggest problem getting the engine on the dyno will be the wiring harnesses. We believe we have a very interesting workaround for this, and if it all works out, then that will be another first. If this works out, it will be another sellable product that has much farther reaching applications than just putting an engine on the dyno. But this is all many months away...so I'm not sure how much of it will work and how much of it won't. We'll just have to see when we get there.

Looking forward to how the stroker behaves with tonns of boost. I'm sure it'll be great.

Gintani just made 770whp on an S65 with a slipping clutch and a base tune. I was unaware if this was a stroker or not though, but good god almighty that's 200mph texas mile power

The Gintani car at Bimmerfest wasn't a stroker. It was a sleeved block with 18.5 PSI @ 7500 RPMs. At least, that's what Alex told me at Bimmerfest. He didn't tell me the displacement, nor did I ask. But I'm told it's 4.0L. It was also MS109, not pump gas.

That would definitely be a 200 MPH Texas Mile car...no doubt about it.

Here's the entry it made in the s65 dyno database:
[email protected] Dyno Results: 773 HP @ 7500 RPM

Thanks for sharing all these details!

Considering I have this obsession with sexy headers, I can't wait to see your finished setup! :cheers:

Hopefully the build is continuing to progress successfully!

I will be working on the project tomorrow. We're at the phase in the project that we can't post any more pictures for a while. The stuff we're working on right now will be sold as separate products. So until the time is right, the photos are taken, but not posted at my photo site. Sorry about that. :(
