Hello everyone, I found this on turbobuick.com. It could be a good answer to our turbo charging needs. This kit is for LS1 comaros but if it works for them i know we can make this fit our cars with only running about 5 to 7 pounds of boost, One thing is for sure it will be much cheaper than the way i am considering with custom hearders, and i will be able to keep the A/C here is the link i hope it works: http://www.ufba.org/forum/index.php?board=16;action=display;threadid=3476;start=0 Robert
i believe i saw pictures of the camaro in question. had the exhaust merged into a single pipe, with a return pipe going back to the engine up the opposite side. turbo behind the rear with a filter on one side a very short exhaust pipe on the other. seems like it wouldn't create much boost, and can you say turbo lag?:eek2:
yep that is the car yes that is the car in question, i couldn't post them though it said they were too big, anyway.. if you read through the posts the maker of the kit answers just about all of the questions they threw at him.. i don't think lag would be that bad considering i have a huge front mount on my GN and it spools well, even still it might work with minimal effort on a car like ours and we have way more room than any f-body would Robert
lag lag lag look like it would have plenty o lag plus all the dirt off the rear wheels into air filters.maybe one good smokey burnout..what if oil line blows . it could sound like knock knock knock not too thrilled but i was at the junkyard today and they had a small chevy with a paxton blow thru the throttlebody. i really wanted to give that a try. mines not worth .02 but i said it anyway andy:TU:
Sorry, but I think that this concept is borderline rediculous. There is squat for exh velocity that far down the pipe, etc etc. I won't even get into it. It's too silly to even consider. Fugedaboutit! Andrew
nah sayers Granted, It looks a lil crazy at first but if anyone reads the entire thread it seems to be the real deal and the guy is pretty good about everyone else questioning how real it is. I just say give it a lil time and see what happens p Robert
I know how to fix all that mess. Roots type Whipple blower, belt driven. Or, take the exhaust scroll and impeller off that turbo and belt drive the inlet side, like in Vortech. And, mount it where it should be mounted, on the engine, not on the trailer behind the car being supercharged.
I had that idea for a while but I would put it in the passangers seat. so its just a bit past the Y pipe and it should make it possiable to run without a waste gate or an intercooler. Matt uzzled:
Stick some mini hood scoops into the body on the back near the side. [like a pantara] and have dual ram air scoops feeding the turbo.
Uh, just out of curiosity... since there is PLEANTY of room in the engine compartment of most Buicks that came with 350s... why not just put it there instead if IN harms way and so far from the exhaust gases? Thats a long way for air to travel...
Re:New LT1 Camaro Turbo Kit Reply #11 on: May 22, 2003, 09:28:49 pm Cool we got lots of interest in the Turbo Camaro. It is way fun to drive. You guys can call me and come by the shop if you'd like. We are just off 8th north and the freeway in Orem. Like to see some of your stuff. As far as big time lag, you have to understand how turbos work (not that you don't know how they work) but there are lots of things going on besides just hot exhaust going real fast. First of all, if you took a turbo off of a conventional system and put it in the back you would definately have big time lag, mainly because the turbo is sized for the volume of exhaust gas produced by a specific engine size at a specific exhaust gas temperature. Our turbos are sized to operate with a different exhaust temperature (about 500F cooler) So, turbo housings are smaller - which increases the velocity of the gases. Cooler gases are denser-driving the turbine wheel more efficiently. Extreme example would be trying to drive a fan with air under vacuum (real thin) with lots of slippage vs. driving a fan with a water stream (real thick) with very little slippage. Or, imagine an airplane propellor (prop pushing air is alot like air pushing prop). At 20,000 feet the propellor is not nearly as efficient and has to spin lots faster to produce the same results that it more efficiently produces at sea level. Geez, what was the question again? As far as long intake tube, if you look at the length of tubing it takes to go from turbo down and around in front of the radiator and through a large intercooler then back around and up to the throttle body, it isn't much different than our systems. You also need to look at the volume of air produced by an engine making lots of horsepower. Good generic formula is HP/10=Lbs/Min of air. So an engine making 400 HP moves about 40 pounds of air per minute. When you send that much air down a 2 1/2" pipe it takes a millisecond for it to travel 10 feet. Hope that answered some questions. Sorry to bore you with the essay. Speed safely! Rick @ STS 801-979-6554
I heard mention of putting geared downed big buick smog/air pumps on a v6 for 5 psi. BS or hmmmmmmmmm Matt uzzled:
I, for one, do know how a turbo works, even a supercharger, having prototyped quite a few systems on motorcycles and cars, and I do know one thing, that one ain't worth the effort of changing the A/R all over the place to get boost at a reasonable level/rpm time. Like I said, hack that exhaust scroll and impeller off and drive it with a belt, in the engine compartment.
well until someone makes a template for a supercharger or some turbo headers this idea doesn't seem so bad, or unless someone is willing to give me 1000 for some coustom ones :laugh: , really what would be nice is a bracket that would make all the accessoies as they are in my GN ... Anybody have anything on the drawing board yet? Robert
Seeing how the accesories and bracketry will swap between a 231 V-6 and a V-8, how come the entire set-up off a turbo V-6 wouldn't work on a 350 Buick.I understand the V-6 is injected, but, you could even use the inner-cooler system from a GN. Seems like this would work out real simply....o No:
Remember that turbos run off exhaust gas, so you would have to modify the headers/manifolds. I don't even know if simply welding in another tube would work because the 350 has a higher deck height and I believe the port arrangement is different (beyond the obvious fact that there is one extra port per side). I've thought about it too, but I think it would jsut be too much work.
Long ago, when chrome-plated, octane-guzzling giants roamed the earth, there was a turbo on the little 215 V8, the engine that was the australopithecus to the 3800 V6. Buick sold Rover the runty 215 in '63. It became the Rover 3.5, and if you want to turbo your 300/340, the brit's have been making screaming turbo cars with the Rover 3.5 family and sell the turbo exhaust manifolds. Somebody around this site has pix posted, look it up. (Sean Etson's single-plane intake is also a modified brit/aussie piece, just to show you what others have done with the predecessor to the 300). You won't need to expend as much research or effort if you go with a Vortech, Novi, Procharger, or Powerdyne as with a turbo. But to see how evenly the turbo stacks up against the Novi , just see this month's HRM. Did I mention that you can get a professionally rebuilt T04 for under a grand, versus the 2K+ for the belt-drive centrifugals? How about sequential twin turbos, one from a scrapyard turbo T-bird, one from a junk Mitsu? How about for less than $700? Of course, eliminating the feedback oscillation from the boost controller loop....
part two: I think the particular location and routing of the turbo setup referred to in the pictures sucks. Were they trying to hide the turbo? No visible air cleaner, and the blue pressure tubing leading back and down gives away the fact that something is afoot at the Circle K. Best hidden turbo I know of was inside a '72 or '73 Pontiac fender, near the cowl, out of sight. The ducting was factory black air intake duct over the pressure tubing, leading to the fender, where the intake was on that car originally. The air cleaner box looked factory, and was a modified original part, amazing that the little 1/4-20 stud was all that was needed to contain 12 psi of boost. Sure, if you looked closely, you could see the exhaust crossing under the engine, and the lines to the butterfly shafts on the Q-jet, to keep boost and fuel from spraying out the ends. But it was a lot less obvious than the Camaro in the picture. Gee, just think what you could do with a capacious Buick and a small pair of blowers! Incidentally, could you run a Paxton off a flywheel? Would the ring gear stand up to it? Wouldn't that be a cute place to hide a centrifugal blower? Quite a drive ratio, too.
