I have talked about this in the Past. We need some Funding for R&D This guy Brad Wise could Help us out check out his web sight and his New Head I new about his heads he was work on over a Year ago. Mybe i am blowing Smoke seem like i can never get a nuff Buick People to step to the front with any kind of R&D Funding needs to be a group to do this what do you Buick People Say?. www.wiseperformanceengineering.vpweb.com
Good luck Jeff if your looking for a group of individuals to fund a proposed project.. that's a tough beat these days.. I agree we need a better head, but am pretty sure someone is going to have to produce it, and fund it, to get it done. JW
I was under the impression that the Board member, Ken Betts, that once worked with Kenne-Bell, is in the process of developing a high performance head to be used with the new TA aluminum block.
Your right Jim have to try i do not no if we have a Nuff Hard Core Buick Racers to step up and Make this Happen. I am looking at a Head Looks like a Stage 2 Head but Flows 450 CFM + out of the Box. The T/A Blocks are out now we need Heads. Head Program is money $75,000 a Little Less than a Block Program. Is there going to be some people that step up and Help or is everyone going to wait for Mike as always?. Buick People Need to be open Minded we need something.
I think after Poston, Mondello and Bulldog people are leary about throwing money at stuff that isn't already packaged and ready to ship. If someone actually needs the heads and can make money off them than they'll show up. Until then people seem to be doing just fine with the current offerings. Could always nag TA to finish up them stage 5 heads.
Here's one for the Pontiac Crowd: http://forums.performanceyears.com/forums/showthread.php?t=684115 All it takes is $$$$$ and time.
See, here we go again, People are just happy with something that is not rt for their car and still complain because when they want to go faster, there is not enough cylinder head there to actually do it. I wish I had the money to fund this project because I'll have several top cylinder head developers out there helping the company to achieve the best cylinder head possible for majority of the street/strip and cylinder heads for the strip only. Yes there is a such head, it's called raw forgeing and you finish the head to your engine and not have 4 or five heads to choose from. Buick is the last of the American made engine's to have to have a good flowin head. Yes T/A tried but it does not add up to what some of the fast boy's want. T/A heads can not flow enough to support large amount of Horsepower in which their is alot of people out there that want a such a cylinder head. I'm glad I have people that can C.N.C. a cylinder head out of billet to my spec's for under 15k and actually work the way I intend it to work. yes pricy but it will beat any head that any manufacture has made and have room to grow if I want.:laugh: oh by the way that is complete heads, Valve's, keeper's, retainer's, spring's, roller rockers, Push Rods, and intake and exhaust flanges. Does any manufacture out there do that? My guy does. :laugh: Good flowin heads cost money period and if wanna go seriously fast it will cost you no matter what.
I didn't know they even had a stage 5 flowed yet. I was under the impression they had a single unfinished one sitting on a shelf waiting for a demand. I'm not really on top of that stuff so it wouldn't suprise me if I was a year or 2 behind.
Stage 5 - Square Port is dad's personal heads for the Wagon, 400+ cfm. Stage 6 - Super Port never got farther than prototyping, it's like 450 +- 15 cfm. These heads require a lot of special valve train components like offset lifters and rockers to achieve a big intake port.
Jeff, How much HP are you looking to make?? 400 plus CFM is a lot of air and if you plan on using any power adders then you will wayyy more than enough air. Mike, Tell dad he needs to get that wagon out and race it!!! Or he needs to let you take it for a ride!!
If You're Starting From Scratch, Why Not A Hemi Or Overhead Cam Design With Even Spaced Ports? Knock Those Chevys And Fords Off The Mountain !!!!
No power adders 500 + NA Engines need big Heads if your working on making 2.9 Hp for every Cubic inch so lets do the Math 500X2.9= 1450 HP I want run some N/A Class need better Heads
2.9 hp per CFM or 2.9 hp per CID? Either way... good luck!!! Lets just say it is 2.9 HP per CFM. My current cylinder heads flow 356 CFM. So 2.9 x 356 =1032.4 HP. I do not know anyone who has been able to get close to 1032.4 HP with a naturally aspirated engine. I think I have a pretty good engine naturally aspirated engine and I doubt that I make 880 hp. So 880 divided by 356 = 2.47 HP/CID I have heard some others say they are able to get in the 380s with the new T/A cylinder heads. So.. lets do the math 385 x 2.9 =1116.5 hp. Lets just do 385 x 2.5 = 962.5. Has anyone in the Buick world done this? Maybe Scotty? No one has with a naturally aspirated engine has used up the air we have today. An NHRA Pro Stock engine is 500 CID and make a bit over 1300 HP. This engine turns over 10,500 rpms and carry of value close to $100,000. I would like to see someone use up the potential of our current cylinder head before Mike or anyone else spends the time and $$$ to make a new one. Now, I have talked to Rod a few times and he claims that he needs a STRONGER cylinder head. He has a need for a new cylinder head!!! Good Conversation... I have talked to a few cylinder head porters and I think there is more potential HP in our current cylinder heads if we would stop worrying about overall CFM numbers and focus on velocity and runner volume. I would do this but I really need to get my boys through college first...ou:
I don't by the 2.9 HP for every CFM I have Stage 3's that flow in the 380's my New engine is Very Hi on Compression alot money and time spent on this Deal Custom Pistons Intake Manifold Camshaft Profile 500 + inches and we are shoot for 2.5 hp for every cubic inch so 500x2.5= 1250hp. You look around are heads are very small. I see small block heads in 430-475 cfm world. My Buick engine will not hang with 975 to 1100 Smallblocks with you say a 880 hp Buick engine
John these are the two most important things we are dealing with on the dragster.. We need to have alternating intake and exhaust to help keep the exhaust runner temps down so we don't have a blowout:error: . We will most likely be using a Chrysler intake as one is already available for our needs. The alternating exhaust compared to stock we do not see as an issue because anyone running at this level will be running custom headers. We will be running between 20-30lbs of boost, so as you say it is all about velocity and strength.
Jeff, To make that kind of power are you planning on twisting it to 9,500 rpms? NHRA prostock guys are barely making 2.7 HP/CID. My engine is 535 CID with 356 CFM. Custom pistons with exotic ring packages and a bob weight if 1684 grams. I have talked with Jason Line on how to make more power. He suggested 2.75 to 3.00 main journals and 1.88(Honda size, maybe 1.80?) rod journals. He thought smaller journals would make more power than a lighter weight crankshaft although at a certain point a lighter weight crank is necessary. No one at this time makes a 53 lb crankshaft. I have talked with Sonny Bryant and he wants 11K plus tooling costs to make 3 of them. You will also need a sheet metal intake with two dominator carbs or split doms. John, I would love to hear more about the "alternating intake and exhaust". What does this do? How does it help lesson the heat? Take Care...
John Pro Stock Motors make more than 1300 HP more like 1400 +HP there heads are way better than 356cfm Pro Stock heads are in 520 + cfm. http://www.youtube.com/watch?v=rKH2RWZdZhM You have a heads that flow 356 cfm is a Stage 4 you have alot more work to do. Your car goes how Fast and weighs what?. Not Bashing. We need better Heads and guys like you that says we don't never steps out of world of Buick Racing or Bracket racing. I want a Head that can flow make Power as well as some other Heads out there. I am wanting run some N/A HeadsUp Classes.
