Tunellcram
 

Keith Eickert tells me Pro-Filer will be coming out with a unit that will have the injector bosses built in .....but of course that news is a bit late for me.
Here`s the progress on mine.

That’s bad ass

Last pic, is it an illusion or someone doink that tapered seat up?

good eye,its damaged,can be fixed and then lap in the fiiting to it.

ya , someone along the way hit it with a sander or grinder .. going to try and sand it smooth and definitely pressure test .

so,,when you get these heads,,what are you doing w/ your old tR?asking for a friend.:D

She`s a tall B itch

:drool1: :cool-smiley-011: Butifus! That's some serious cram.

getting into Pro Mod territory, I dig it

HMMMM, :cool-smiley-011:
Wonder if anyone has one for a rear feed Whipple?
BTW That belt is too short. :drink:

That is cool. The only two downsides I see are the 1000 lb lead keel required to keep the boat from being top heavy and the fact that the intake charge is at 1000' MSL. :D

J/K, keep up the great work.

Looks great.

Still waiting for pics on air redirection things people make in plenum to distribute air from rear exit whipples.

this was an issue on these motors too, right ?

Looks like fun

:)

I thought it was but I have no proof and my plugs were always evenly colored. Seeing the one video with the clear intake and how the fuel and air gets all crazy in there I don`t think it`s an issue.. but to make sure I have even distribution I put the extra injectors in the runner.
a 12 02 dyno will tell me more.

nice valve covers
did my shipping guy send you a foam block too ?? Lol

Tunnel crams have been shortened and ported (well one so far since November) and I can start putting everything back on my longblocks.
I now have around $3600/intake into these, I could have just bought a custom sheet metal intake so kids don`t be a dummy like me and instead of having Tunnel Rams modfied for port injection and then shortened because they are too tall , just custom make one, thanx .
Learn from my mistakes.:cool-smiley-027:

On a good note....yea you have a ton of money in them but at least you will be the only with them and as usual with everything you do they look absolutely b!tchin!!!! Would have been cool to do a back to back dyno pull to see what you get out of just the intakes alone......

So did they simply milled down the plenum a good amount, they did NOT cut runners off and reattach to plenum, correct? If so, how tall was plenum before, how tall is it now, thanks, Smitty

The top got milled and retapped , ported the intake .
It was 10.75 tall and now it`s 9.5 ..

Of course this dildo hogged out the intake port too much :cool:

Nothing a bit of Z-Spar can't correct. Just be sure to coat it if your running alcohol.

:picard1:

it's hard to see in the picture. Is the bottom of the intake and head lined up? Or is the intake higher?

The bottom lines up..
I`ll address and port match it next time, sending it for now .

be careful with it misaligned like that. fuel tends to hit the port and stop being atomized with the air. then it starts to drip off the edge causing it to load up at an idle. when you clear it out, air velocity cleans it off and it gets even richer. it wont be something you can effectively tune out of it.

Oh great , I just keep getting more and more good news with these damn intakes.
You can see the injector hole.. 50% thru blower 50% thru port injection.
I guess Ill find out how that works out, thanx for the heads up. when it`s rich at idle I`ll know why at least .

What a $hit show. I should have jut kept my old intakes but nooooo, I had to try something different .:argue:

:(
that would drive me insane

I can`t see it, it`ll be fiiiiiine
:whistle::D

Interesting read on the subject.

You or the guy that modified the intakes?

The only thing IMO about that article you linked that makes it sort of irrelevant in your case.
You're way above an average street engine and the margin for error diminishes the higher you go.
^^^ Splash Zone those dudes up.

Dan,

Just a thought.....

Get some Dykem spray layout dye, and give each intake tunnel a shot or two, making sure to sufficiently cover the mismatch. Let it dry. Remove your intake. Scribe a line around the perimeter of the Dykem. With an 1/8" carbide end mill in a Dremel and a steady hand, carve away that mismatch and forget it. A little bit of lacquer thinner and the Dykem overspray is gone. Yes, you will have to be very careful to avoid getting any aluminum chips into the nooks and crannies, and very diligent in removing any that manage to get in them.

Dykem Spray Blue

IMO that's the worst thing you could do.

Under,

Why is that?

Always up for an education. Really.

Thanks. Brad.

If you start grinding a taper on head intake port, that would probably affect the air flow into the head and make it very turbulent and flow less. It will also kill the value of those heads. You would never be able to sell them, if he wanted to. It's a shame the intake was ported so much. It looks like it is ported larger than even the gasket. The correct way would be to fix the intake. Years ago i had a friend helping me do some work on my house. He started doing something and i said, "that doesn't match the other side of the house". He said, "you don't match something that is wrong. You fix it correctly". Sucks the op is having these troubles. But i certainly know how he feels. It could be my life story. 

But without testing it may or may not, have the heads been ported before? I think the reason he isn't is that the heads are on and not coming off, those little chips would get somewhere not wanted.

Under,

All fair points, pretty much what I expected, and I wouldn't disagree with any of it. But....

In an absence of any engine building experience, I try and rely on the physics involved, which I do have a pretty strong grasp of. Not to suggest this overrides real world empirical knowledge. In a NA build, a less than smooth transition from intake to head would likely be more problematic. Obviously, a restriction inducing contour would be far worse, which this wouldn't be. But, in a boosted build, such as these, I wouldn't think it would matter so much, even if less than ideal, and it would certainly be better than that square corner the oncoming fuel/air has to navigate. Hell, just knocking that square shoulder off at a 45° angle would be better than what he's got now. At least then the fuel wouldn't collect on them. I don't see any gasket exposed, so doing this work wouldn't compromise anything that isn't already compromised. I don't see any fixing the intake. I would never trust JB Weld or any other filler material. I've seen way too many chunks come loose in our model boat engines over the years. With the heat, vibration and fuel, that would be a hard no from me. Welding it would be a potential option, but that would mean a FARQ-TON of welding to achieve anything near a smooth transition, and that would warp the crap out of the gasket faces of the intake, requiring machining, putting him back in the same spot. I also don't think Dan started this build with resale in mind. That said, it is of consideration that, should he decide to abandon the intake for whatever reason, this work would, in fact, render the heads to the scrap heap, as well. If I were into this project as far as Dan is, I'd work the heads to make them as smooth a transition as possible, assemble the engines and run them until they blew up (hopefully a good long while) and start over with the wisdom he's acquired to this point (learning from his mistakes, as he puts it). From what I've gathered talking with him, I'm betting he'll be building the next engines in his head as he's running around with these under his butt, pretty much from the time they get wet the first time.

Dan's obviously got some things to consider. I'm really hoping he gets these beasts running right. He's promised me a ride come PokerRun weekend at Cumberland. :ernaehrung004:

Thanks. Brad.

Wildman,

Indeed. Chips get everywhere. And I mean EVERYWHERE. I would never even consider doing this with the heads in place. Which is most likely why Dan said he was "sending it for now". My only reason for making the suggestion is that NOW is the time to do something, if you're gonna.

Thanks. Brad.

Lol I read that whole thread and thought well look at that maybe I`ll actually make more power with a step in the air flow ..lol

Brad the heads and all valvetrain is installed.
I hate going backwards, and I need to start making progress if you`re getting a ride ;)

Cheech, the dildo is the guy I had shorten the intake..

Dan,

Just so your priorities are in order. :ernaehrung004:

Thanks. Brad.
