Micah......Stop teasing....We want to see 10k rpm and with heads, intake and throttle body that can flow like a beast...

Soooo....this thread is still pointless.

I agree that saying there is no point to a 2.34
when u have a 2.5 is a silly point, it's physics. They will be different, undoubtedly.

the motors will behave differently and some may be a bettar fit then others
i'm building my own with other peoples cast of parts in my bedroom

Well, I really can't, literally. I have NDA's with all of my old development engines. I will be sharing some of the stuff that I have with guys from this year. I imagine you guys will have something to stare at before April is over.

I fail to see how the thread is pointless?

They are out there and have been for a while. It's just no one with them are posting much about them here is all. I don't think even Dom has said much on this thread about his 2.34 but you can and will find plenty of threads full of information.

And Micah:

Damn NDAs

Well at least give us some info that the NDA doesn't bar you from telling. Like do you expect to hit those RPM numbers without a dry sump? If so how? What provisions to the heads are there for such a high spinning motor? How about harmonics? How about who do you have this NDA with?

Hopefully at least one of those aren't covered under the NDA

Man does this sound like a prelude into some nasty April fools joke....lol

Etos, I do strongly believe in what a 2.34 can do, I am more saying that I trust in what dom and micah have been doing, it's great...but giving people Ed the ability to say it's pointless is possible because there simply isn't enough data yet and now more people are keeping their 2.5's alive(e85 and more knowledgeable tuning is doing it IMO)

His nda means that he must have found something that he doesn't want to share yet because others will copy it and take his hard work. Kind of silly to ask him about that, also it could be unproven so it's just not time for him yet.

I think a lot of new stuff will be down to hardening parts like sleeves and, pistons, and bearings with shot peening or Wpc treatment on parts that can't be shot peened (pistons, bearings, etc. Possibly even rings) while holding those tight tolerances. His pistons are probably just reinforcing the lower pin height, I would guess.

you would be achieving the same powerband without, with more tq and essentially faster response by not needing to be as high up in the RPM range to make power
because you'll be in a shorter gear.

how about word on those 77mm cranks that i know at least dom was trying to get sorted?

last i saw he had a manufacturer lined up but they were inconsistent in even their OEM spec 79's and so forth, so he cut them loose.

That company lately has been more than willing to make things right, and doing a lot better with thier cranks and have apparently resolved the rifle drilling issue.
so maybe in the future we will be having 77mm cranks made.

Are you in some sort of a race series, have no issue swapping blocks on a regular schedule, have a good understanding of your engine and making in the realm of 500+whp for your events?

Yup, had my lawyer draft them up after two shops tried copying the design. The other reason is all the engines have been an evolution in design tweaks...now the aluminum piston models are available to the market with no NDA. Actually have a group buy order going out in three days.

I actually need to catch up with Dom. I know Scat will do them at regular pricing if you buy 5+ of them. But then again that's a Scat crank.

Micah,

I am not in a race series no. I didn't realize that was one of the requirements. I am just ready to build my block to a 2.35L or your 2.43L destroked from my 2.5 2011 STI....

I am a street sweeper persay....The guy that drives it everyday and races as much as possible every weekend....

I can give you a real world take on daily driving your combo at decent horsepower levels....low 500's for daily driving and much more for weekend fun....Depending on your build and internals I would love to run nitrous on it as well....

I completely understand if that isn't what you are looking for....

Well the biggest part is you're going to need to be able to rebuild your engine every 4-6 weeks and send the old pistons back to me and you cover the rebuild related costs...that and my wallet for freebies is empty.

id be willing to test parts and pulling the motor often is no problem. Id want a deal on parts though. Not 5 finger discount just help. Still on a 2.5 though myself.

Micah,

Let me look into the actual costs of the rebuild. Is there any benefit running this bottom end with the stock heads or do the heads need to flow and rev to 9k rpm?

Well i see that some people haven't seen much data and proven performance and so on but i have been using a 2,34 motor now on my RS witch has a motor built by myself (i know this thread is about maxwell blocks but i think mine is very alike those they build

So i am just gonna throw out here my experiences on the motor

So it has a Pauter x beam custom 134,5 mm rods
Darton sleeves 99,5 bore
O ringed stainless wire
Custom 10.0 compression manley pistons with the wrist pin 2mm higher in the piston
stock head gaskets
ej255 heads not ported not even portmached
cosworth 278 cams avcs unused and dual springs and ti retainers
Stock ej207 crank
ACL race bearings
arp L headstuds 11mm

I raced the whole last season on it using mobil 2000 10w40 oil
Multiple 9 second passes 20 plus
and clocked best 9.85@145 and best trap of 146 miles

I have the Oem 10mm pump 2extra shims
i reeved it past 9500 in every gear
the bearings and all looked very good after the season
I have a s366 borg warner turbo witch it makes full boost by 4300 rpm in 4th
the motor saw 40 psi and no problems at all
Looking forward to the next season with a few mods like s3 gsc cams and more


here are some more info and all i can say is i would recommend this motor to anybody anyday best option for everything and makes awesome power

Pictures of the build http://www.facebook.com/media/set/?s...1473018&type=3

sorry for the thread jacking

^^^what a great public endorsement to hear. What did you do about the .5mm missing from the rod and piston total length? did you leave it in quench height, take it out of the deck or run a gasketless setup?

As for the S3 cams, I've spent some time talking with the guys at GSC and I'm looking to test a set as well as their ovate beehive springs...shimmed a good bit for the RPM we're seeing. I'm hoping they don't relax like some others I've been pushing.

I am sorry the rods are 134,5mm not 134

and what Rpm are you planning on reeving with the s3 cams

I don't see why anyone is shocked that the 79mm crank make more torque at a lower rpm than the 75mm.
As for what the big deal is with the destroker, I would say that it provides another option for our current gearing. If we could change ratios on a whim like the v8 guys, then a widely spaced gear set combined with a torque monster makes sense. I think a destroker might be a valid option for 04-05 6 speeds. The destrokers have the same curve as jdm v8s and they have the same close ratio mentality. It's just that I haven't seem much data in terms of ignition timing and fuel requirements. Id also like to see a destroker tuned Evo style, 4 psi up several degrees timing pulled back. FWIW high rod ratios help crappy exhaust ports, so I'd think the engines would respond similarly.

If you look back at DSM and Honda drag racing, they made the powerband fit around the gearing for a long time since that's all they could do. Their strategies changed when custom gear sets got cheaper, and you started to see more strokers.

I think the question is to compare setups. Would a 2.5 paired with 07 gearing be faster than a 2.34 with 04 gearing? I just know that I'd prefer the 07 and the wider ratio on the street. I never thought I'd say that I'm getting tired of shifting but I am. I'm old.

I'm guinea pigging with them. We're going to run their springs, shimmed pretty heavily and see if the springs will stay alive at 10k for road course duty.

That'll free up some hp if the springs survive vs. duals.
