You and I both. Flow sheets would be awesome. Dyno runs also. That would be cool.
Exactly. High flow through small ports is nice to a degree. The W2 will flow in the high 2’s low 3’s with a larger port and that is just simple more air and fuel which equals power. A no brainer.
RAMM ROD and YELLA BELLY ROSE... chill dudes. You both are a wealth of knowledge. Lets just see how good the TF heads are when they get out to the public and stop calling each other hypocrits please and thanks. Or cage have a cage match and settle it like mens LOL
Its really not that hard to hand port a head to flow better than a cnc'd head if you know what you are doing. cnc'd heads are ported to a safe level by whoever they hire to port one for a cnc program. Good or bad it is what it is. A good hand porter can port a head personalized for each custumer.
I started to follow this because I am interested in these heads. They are a step up form what I have and are better quality. I like to experiment with things and make my own decisions. I use to race back in the 70' and 80's, we had a Pro Stock car. I have built several cars and do restorations now on a private bases. I do not claim to know everything and expound on it. I am not a self proclaimed expert and have to reply to all threads and tell them that they do not know what they are talking about. I know that technology has change over the years and has moved on pass what I have done. I just have a street car that is fun and that is all I want and to play with it.
First of all, I never said what I thought of the new TF offerings because I've never seen or touched a set. YR can tell from a picture that it won't equal or exceed his W2/W5's which flow 355 BTW. But precedes that with "flow isn't everything" Now i'm not confused by this but some would be. If I were releasing a new product I would be pissed that I didn't hire a guy like YR to design it because apparently it's all wrong. Wealth of knowledge? Dunno about that, but I do know I actually contribute with REAL information in REAL build threads. I've yet to see ANYTHING substantial/factual or relevant from YR. Heck I'd settle for mildly interesting at this point. J.Rob
Seems I've posted about my W-5 junk many times, because many said you can't get a 2.100 valve in one without moving the guides. But you can. It would be better with a 2.08 though, unless you use a 1.500 exhaust valve.
You can't look at the pictures posted here and see what TF did? What they always do? It's a marketing trick. Always has been. Pay attention. I Didn't say what the TF head will flow and I don't care. It could flow 900 CFM and it won't make the power of a 1970's designed W-2 head.
The flow sheets went with the heads when I sold them. There were probably 25, maybe more as I don't recall. And that was only the tests I took results from. The heads were on the bench so many times I could never count. The dyno sheets were in the file that went with the car when I sold it in 2007. Didn't know that until I moved in 2008 and I was looking for some pictures I had of the car. They all went to the buyer. That buyer sold the car. It been in several hands. Last I heard, it's about an hour from here. I can't verify that. All the rest of the flow test I did went with the flow bench when I sold it. There were some really nice heads in that folder. I should have at least kept copies. The guy who has my flow bench is in Seattle. Haven't talked to him in years, but if I thought about it long enough, I may remember his name.
I know I can hone a cylinder and port a head. It ain't that hard.
Once again, relax, sit back and relax. Not for nothin but your jumping in this guys shit like he has a hard on for you and I don’t see anything like that, not one bit. But your jumping on him. RELAX!!!!!! The more you fire back the worse it gets. Stop making mud in an otherwise good thread. Good GOD MAN! RELAX!!!!!
I see this thread has gone awry in a hurry, so all I have to offer is some additional info. First, fully CNC ported refers to the intake and exhaust ports, as well as the combustion chambers being entirely machined with a CNC mill. It does not mean max ported. Even an RPM head could be called CNC ported because of the port entry being CNC gasket matched. They are definitely not fully CNC ported. The Trick Flow big block 240 heads are fully CNC ported, but the 270s are fully CNC ported bigger. The flow chart sent by TF, says 293 at 600 and 301 at 700. For 190 ccs and a 2.02 valve, that's respectable for a stock replacement head. Exhaust is about 240. From past experience, Trick Flow won't even sell a bare head until about a year after they are released. They want to build a reputation for the head before they offer them to guys who will modify their work. They don't care if someone makes them better. It's the hacks that they are afraid will ruin the heads reputation before it has been given a real chance.
They did with the big block heads, so the final production version will likely have lots of room for pushrods.
Is that vane actually curved over, or just an illusion?
YR has nothing to prove, Ramm has nothing to prove. or do they? maybe a build off with the new unproven Trick Flow small block head. say 420 cubes!
It is actually curved that hard.
Yep. Agree. The cnc they are going to offer doesnt appear to be a max effort type deal. Just the name “ street port” kinda says it all. That said, for what i want to do, if those are good numbers and the head “ works good” it should suit me as is. I posted those numbers on your thread on Moparts a while ago.... lol
Yep it's curved. They do that to because it looks good on a flow bench. I don't force air to cross the back of the valve from the long side to the short side. That was trick in the early 1990's. It's a waste. That's why I asked about an unported casting. It will take me just as long to fix that as it would to just do my own port work.
No way would I use that head on 420 inches. Not. Nope. Nada.
I hope TF made the castings able to accept a W2 type port layout in oval and rectangle. Would be nice to see someone other than Indy offer an aluminum head in that configuration. Consider the number of big inch small blocks out there these days, a reasonably priced quality head easily capable of making 600+ HP OOTB is sorely needed.
Why couldn't you get a 2.1" valve in without moving guides? A quick measurement and simple math tells us valve guide spacing is 1.875" =/- .002" a nice nominal number. So half of the valve diameters added together better be less than 1.875". I get 1.85" with a 2.1/1.6" which should leave .025" between valves--your valve guides better be good and valve train stable. W2/W5 OEM heads all have the same spacing. Also most off the shelf pistons barely have room radially for a 2.08" . J.Rob p.s. See YR, it's not so hard to add actual information. I even added a picture for you.
Like is said before TF should have put you on the design team-no telling how far you could have taken them. J.Rob
Looks kinda like GM's LS7 and some of AFR's offerings like their SBC 235. J.Rob
Ramm bored and HONED my engine and the rings sealed instantly so I know first hand he can hone a cylinder .
Tempted to make a run up there this weekend....
