John.. :moonu: Wait till we put the technology you guys use, on a big motor.. and it's coming.. JW:laugh:
and also you get to hear the famous " Is that antifreeze that I smell??? uzzled: :grin: :grin: Sorry, just coudn't resist taking a crack at that one Jim & John. :laugh:
Beleive it or not, but the chevy crowd is very glad that buick exists. The reason is what John S. has stated, the V6 camp and I have met a lot of other brand racers that do know about the ability of a milder buick V8. The turbo camp has kind of put buick on the map and now the technology that they helped develop is going on to bigger and better things. Conley is still using the technology from the V6 days and has brought countless other off branders to the turbo camp. Now a serious V8 buick turbo effort may be able to be completed without fear of $20000 worth of parts being scattered from here to next week when it lets go.
Jim B, I missed your announcement Jim, I somehow missed the discussion about your block. I applaud you for being willing to undertake the challenge, and know that you have the knowledge to see it through. Never forget that the first guy to the finish line is the one remembered. Too, if your block comes on line first, you will get the sales. A bird in the hand, etc. I assume it has a very beefy bottom with 4 bolts, o-ringed deck, etc....The cutting edge racers will be lining up to buy it. I can see the GSCA trying to protect the iron blocks, though. This should be interesting to watch. Dan
Technology JW Lets see.....Since the Buick technology has been out there for many years (Over 20) and many different people have already tried to adapt this technology to the existing 455 anchor, what's your point. I can read the headlines in the 2007 issue of the "BUILD SHEET". 880 CI Titanium Alloy Blown Big Block Buick with Stage 24 heads wins first heads up Super 16 @ BPG Nationals. :laugh: I hope it happens sooner. Maybe we could have a Super 16 Heads up race at our 2004 BPG Nats. By then, we will have a wide variety of BB's to chose. This could be lots of fun. Maybe we can get a new, bigger CI V6 Stage 2 Block off the drawing boards. Just a thought! PS: All that green stuff under the hood was antifreeze.:gt:
Ya' I know... you brought me a defective car.. but even so.. I made it run 11.50..:spank: You know as well as I all the only thing standing between a 500 ci twin turbo Buick V8, and the racetrack, once the blocks are available, is $$$$$ Lots of it. Heck.. what am I talking about.. who needs to stroke it.. you could run a 400" motor, and mop the floor with the V-6's.. "There is no substitute for Cubic Inches" Carol Shelby :Brow: JW
Talking about a Buick, and quoting a Ford & Mopar lover though ..... :shock: :laugh: :laugh: I'll start my own quote " There is no substitute for Buick power" :TU: Buick power = (chevy * ford) / mopar * 1.5 :Smarty: :laugh: creative math 101
The Substitute for Cubic Inches is Cubic Dollars......:laugh: With turbo technology nowadays a big single can make more than enough power on a small cubic inch V8 to over power any chassis short of a pro mod/nitro coupe chassis. Look at the Pro 5.0 cars, 2000HP out of a 350 CI Motor. Now that we have 2 "new" blocks to support major HP, to bad we don't have Cranks, Rods, Heads and Intake Manifolds to support them..... Keith
At least in the aircraft piston engine world it is understood that one big turbo can be built for more durability than two smaller ones --at least for a given level of boost. Plus by having one you cut in half the chance of a failure of fittings, turbine blades and bearings. At least on aircraft when those turbine parts get ingested into an engine a terminal case of indigestion quickly ensues.
Thank goodness I've been spreading it out over the last 10 years! :laugh: Only a few more to go! I think the flood gates are set to be flung wide open. :TU:
For the guy who wants to save weight, this is the way to go. I would have to guess that the block will cost around $4500-$5000. If you had two identical engines one with a cast iron block and the other with an aluminum block, the cast iron block engine will make more horsepower. Why? because with the aluminum block it wont hold the heat in like the cast iron. This is a serious peice, good luck with it guys.
That's what my engine guy was saying......more power w/iron. So the weight savings could be a wash and the only benefit to the aluminum for the extra money is the repairability factor. It is also my belief that there will be a long wait for the release of the aluminum block.
???? Last time I checked for a turbo supercharged application the amount of the cast off exhaust used to drive the turbo was limited by the max designed turbine inlet temperature(a/k/a TIT). Above the TIT you will perhaps get permanent deformation of the metal in the turbo itself and ultimately failure of the turbo. To help avoid this intercoolers are often used to reduce the temps of the intake air before reaching the turbo. If an aluminum engine as a whole is radiating more heat energy it would seem to me that there is less hot air out the exhaust, all other things being equal, and more cooler air for more boost. More boost available equals more power.
I am excited I think the main point is not really the weight savings or the heat dissipation, but that now guys can build 800+ HP motors and then push a button and shoot another 400 HP down the throat of their 535+ CI AL motor. You guys are probably right about heads and cams, Some more R and D will have to go into future heads and cam grinds that can make some redicoulous horse. Hell, I think I hear a 10-71 calling my name.
Ummm...Nope...The intercooler doesn't cool the exhaust gases...The intercooler cools the incoming air between the turbo and the intake...The turbo, in compressing the incoming air, heats it up pretty good(like over 300 degrees!!!) and the IC cools the incoming air charge...Actually, hotter exhaust gases help the turbo spool up faster, but only to a point...That's why a lot of guys tune by EGT temps pre-turbo along with WB O2 sensors instead of the more crude narrow band O2 and knock sensor...
You are so correct . Made that correction. What is your slant on the advantage of iron versus alumuninum and the holding the heat in argument? Jim Lore
Dumb question, but... Is an intercooler the same as a aftercooler? I was talking to a guy I work with and we were talking about turbos and whatnot. Everytime I would say intercooler, he'd repeat my question and say aftercooler. I thought he was being an @$$, but maybe I'm wrong. BTW...can't wait to see what the big boys do with PAE's iron block this year, and what they'll do with TA's the next. I wish I made more money!!!
