Not with DCOE's. Ill be getting the 50mm OER/SK sport Injection kit to go along with the 3.2L kit I have on order.

So going to run E85, we will see what happens!

You think E85 would change things at all?

I know a few modern day cars that run 12:1. I assume this must come down to a more efficient combustion chamber design or something then. Talking to a few people (who don't run carbs) said not to go higher than 12:1 for pump gas.

Well it might be an interesting test to take my Kameari intake manifold and rough it up with 80 grit, and re-dyno the setup and see if anything changes. I already have a baseline and everything properly jetted from when it was done back in December. According to my tracking info, Slovers will be receiving the head on Tuesday, so I dont really have a lot of time to have a proper decision made only from what my V8 friends tell me and what I have read online. From everything I read, having the walls a bit turbulent when its fuel/air is a good thing and it helps break up that laminar flow along the edge. The idea is that at the surface walls, the wet air moves more slowly than when its not at the surface. Venturies and carbs are always smooth, because its BEFORE the air gets mixed with fuel. That goes back to the fact that when its dry you want it polished/smoothed out.

I still need it to run on pump gas... I dont have good access to race gas.

So talked with Slovers a bit, and he is going to leave the intake side rough for now. Once he evaluates the cylinder head more when he gets it will go from there. But for now the intake side will be roughed up with 80 grit and the exhaust side will be polished. Not going to do the combustion chamber, as roger mentioned, I think it would load up on carbon deposits rather quickly and negate any positive effects. Slovers said they saw early detonation when it was done that way, which contradicts what the article above said. But im not going down that road anyways. This is going to be a monster head, 12:1 CR, seeing 9k rpm. Big ports, big lift.

Yeah it doesnt seem like anything new, it was that I just have always heard of a polish job whenever someone quotes me. I have never heard it "rough' so to speak. Anyone see it done on an L6 cylinder head? Im shipping an N42 head out to Slovers today, and may have him do some changes in lieu of a polish job...

I've always seen cylinder heads with a "polish". However, I was just turned onto an alternative from some v8 friends of mine who are drag racers, which the port is dimpled like a golf ball or roughed up with a carbide bit, on american V8 engines. Doing the intake manifold rough up the same way with carbs installed, I am told allows the air/fuel mixture to better atomize since the fuel droplets are bigger rather than if your ports are smoothed out. Their is debate on the exhaust side since its "dry" not wet like the intake side is with Fuel. the intake port has to deal with wet flow which can cause fuel to stick to the port walls. dimpling or roughing up the walls coaxes these fuel deposits to continue to flow through the port or evaporate because of the turbulence it creates. From some research online there seems to be varying degrees of what should be dimpled and what should not. Has anyone experimented with doing dimples on the cylinder head or intake manifold on an L6? Article I found on v8 engines: http://hotrodenginetech.com/pipemax-creator-larry-meaux-on-race-engine-head-porting/ "I took one of my old chipped up and slightly bent Alumina Burrs and rough ground just the entire intake ports on a big block Chevy Dart head all the way to the bottom valve job angle cut. Back on the dyno the engine gained almost 15 HP on a 950 HP engine. We kept going with the rough carbide finish everywhere in the intake, exhaust ports, chambers and intake manifold from that point on. So far every engine has responded with 15-25-plus horsepower increases, a wider power curve, sometimes 100 to 300 higher RPM point of peak horsepower, less fuel consumed on the Dyno ( lower BSFCs ) and dryer exhaust ports. On the flow bench, basically no flow gains I can measure from roughing up the entire heads/manifold surfaces. On the dyno and down the dragstrip, we consistently see more HP and quicker ET/MPH times"

So I saw John the other day picking up something from him at Ztrix, and your hood was about all boxed up when I showed up. I did get a peak and it looked pretty awesome. Cant wait to see it installed on your ride....

so when do the youtube vid's come out? =)

ztrix.com may have something. He doesn't list all of his parts, give John a call.

I run it. Bought it from TEP as well. Here's the thing about them.... he's a salesman. He's super nice and informative about the stuff he sells. Just dont call up and ask him for help or questions after the sale. He is really short, and wont give you much help. He isnt very technical from what I gather. The electromotive guys are super nice, and easy to work with at the manufacturer which is where I had to go with some questions I had. The electromotive stuff is a very solid product. Just a lot of people dont use it due to other alternatives. There is a lot of history around this product. Once all their patents were up, then everyone else was doing it. Its a pretty solid system, easy to work with, and very easy to install. Just not a lot of help out there if you need it..... Any tuner shop could probably help you out, mine was able to figure it out relatively easy. Instructions are very easy to understand and follow. It comes with all the clips, plugs, and stuff so you just wire up what you need.

yeah someone recommended them for something Im looking to do. Doing some internet searches on them, they have some very interesting L6 engines in there from the paul newman days.I was more curious if anyone had actually used them before, since its not a name I have heard around here before.

Anyone use these guys before? I find it interesting that Frank Honsowetz is the GM, who is also the same guy who wrote the book on "How to Modify Your Nissan and Datsun OHC Engine".

This guy is not too far away from me. He can make any kind of ultra low drag/ceramic bearing you can imagine. He doesnt have anything on the shelf that fits the datsun timken parts. But his price list covers custom part numbers based off the bearing number. Sounds like the real deal. Ill have to reach out to him and see what he can do. "Performance Bearing offers direct replacement ceramic bearings to replace almost any steel bearing. All we need is your bearing Part Number and details on your application to fix you up." http://www.performancebearing.com/bearinglist.html http://www.performancebearing.com/

http://rt-performance.co.uk/ Guy said its 235 euros, shipping would be about the same I suppose. Im still waiting on shipping, as he said it was only 35 euros locally (London). May hit up Ztrix and see if they can make something similar.

really like the looks of it, very cool with the side pipes. I was looking at this universal splitter. Used on quite a few cars from the sounds of it. Someone was posting that they even got banned from using it. Looks like it could work with some minor modifications. I like the channels that are built into it similar to how @Heavy85 had his in page 3.

I saw that posted up on Ztrix.com's instagram the other day. Is John making that hood for you? It looks pretty aggressive, I like it.

I saw John@ ZTRIX.COM post this up on Instagram this morning... is he making it for you?

Thanks jamal. I'll get with you. I believe I still have your number in my previous pm with you.

Hey Jamal, Any info on it?

Sweet looking ride! Do you have any other pictures posted?

Looking for two N42 cylinder heads. One can be just a bare head, but I also need one complete. Let me know what you got. Ported or un-ported is ok.

I just posted the tape info on their time from the video for those who didnt watch it.
