Thanks again Kerry. I ran out of time today. Will check with them tomorrow. Craig it is truely a small world I moved from Fuquay varina to Texas in 95. We lived in a sub division that was across from a well known.Machine shop that was off of 401. The name escapes me They said he was good but he didn't know much about buicks back then. I dont miss those late night drives from RDU airport to Fuquay. My wifes mother lives in North Raleigh 7 miles from Wake forest. We visit from time to time would love to come by and meet you. And see your car.
If you can't find the plexi,Keep in mind it could be made of any plastic,Maybe a pvc fitting or something you could cut up. You could even use MDF or any ''dense'' plywood......
You are right about the part, John R. and I both found out the hard way. Just give me a call 919-656-0469, would be glad to have you over. Hay, I even went to Wake Forest High School, graduated in 1981...
Gary thanks for the options. I must be slow but what is mdf? Craig thanks for the offer. And it was nice talking to you. Kerry I finally got to go to the glass shops that carry the plexi glass. One wanted 26 dallors for the 3 1/2 by 8 inch piece. The other said they dont take orders under 100.00 bucks. :shock: Then I started pricing routers and bits. ou: so I was wondering how much would you charge to make one for me? Thats if you had the time.
Terrance...Looking around I found a 3 1/4" X 14" piece of the 3/4" plexi. I'll PM you and we can go from there...
Hi Kerry, These are the pics I told you about in my PM. These are my first attempts. but as you can see I have plenty to play with. I have a question how do you determine the length of the slot? And is the second slot so you can us it on the other head? Still building up my nerve to start the slots. I dont have any intake gaskets here. so it's taking longer.
The bottom one is my first attempt notice I forgot to center it. Thanks for the idea Kerry. And thanks for the other options Gary Kubisch. :TU:
Hi Terrance, Looking good!:TU: The dual slots are needed for going from one set of siamesed ports to the next set or pair. If all the intake bolt holes were in line then only one set of slots would be needed. An intake gasket is essential IMHO to accurately lay out your bolt slots in relation to the ports...EXTREMELY hard to do it without I would think. I basicly measured the extremes of the edges of the ports to the bolt holes and then slotted accordingly. Good aluminum porting burs (ball-head cylindrical) helped for the final fitment for me as there were slight "tweaks" needed. My slots are slightly oversized so I can raise, lower or whatever needs to be done to perfectly align it with the port then tighten the nuts hand tight and it's ready to go. Basicly make yours with a 1/2" bit. The intake bolts are 7/16" so that gives you some play there. About 1/4" all the way around the port opening I trimmed and left the paper backing on to serve as a leak-free "gasket" as to not induce any possibility of turbulence at that point. Hope that helps...
Hi Guys, I haven't spent a bunch of time lately on these but I flowed them again Saturday and have almost completely eliminated the "hick-up and drop" problem. My most current flow numbers for my TA Stage 2 SE's are: ...........Intake..............Exhaust (w/o pipe).....(with 2 1/8" X 4" pipe) .100 .... 75.0 .................... 69.0 ........................ 70.0 .............. .200 ... 157.3 .................. 128.1 ....................... 135.1 ............. .300 ... 238.1 .................. 176.5 ....................... 187.0 ............. .350 ... 274.1 .................. 202.2 ....................... 213.3 ............. .400 ... 304.6 .................. 222.4 ....................... 236.3 ............. .450 ... 329.3 .................. 239.4 ....................... 255.9 ............. .500 ... 346.7 .................. 250.9 ....................... 272.6 ............. .550 ... 358.9 .................. 257.4 ....................... 284.6 ............. .600 ... 360.6 .................. 263.0 ....................... 293.6 ............. .650 ... 359.5 .................. 264.2 ....................... 301.4 ............. .700 ... 360.3 .................. 265.3 ....................... 304.5 ............. .750 ... 364.2 .................. 265.7 ....................... 305.2 ............. .800 ... 367.5 .................. 266.0 ....................... 306.3 ............. w/open 377.8 .................. 274.6 ....................... 310.8 ............. Notice that between .600 and .650 it ever-so-slightly "hick-up'd" and lost 1.1 cfm. Then by .700 it was only down from .600 by .3 cfm. I won't be happy till I identify and completely correct and eliminate the problem.:grin: But, it is a heck of a LOT better than the 15+ cfm drop when I first started. BTW....I have noticed other various flow sheets posted with an 80+cfm .100 number on the intake side. Now...I was getting the same thing with a 81-82 cfm reading but then I noticed that our SF 600 was actually overcoming the test spring and actually sucking the intake valve open on it's own to about .110" lift. That's where that number was coming from for me. I started holding the retainer with one finger to make sure it was not opening any further than it was supposed to and giving a false .100" reading. Just thought I'd put that out there so others can make sure their bench is not doing the same thing and giving better .100 numbers than what that head is actually flowing.:TU: Please note...this was the ONLY point in the valve opening I found that this was occuring...I double-checked at each and every lift point! I do believe that my Regal is going to be quite happy with these heads!:3gears:
