Hi im looking into parts i want to put on my buick 350 and i was wondering can a blower be put on a the Buick motor? If it can amazing if i cant bummer but just a minor set back. Blake
well people seem to be able to blow just about anything they want these days. the trick seems to be finding the right manifold from what i can tell most of the units ive seen are custom jobs and in my case were cost prohibitive if you want the through hood all out setup. if you are more interested in going with a procharger type setup,its again tricky to find bolt on, but is far easier to man. the mounting hardware than have a manifold machined when i was looking into that ages ago i think they make a kit that bolts onto a latermodel century but was supposed to fit engines with 350 ci displacement,so thats a lead at least,and am sure someone with more knowledge than myself will chime up if given enough time as you are in the right place after all. oh and to satisfy my own selfish curiosity while on this post would be interested in finding out if anyone has dealt with these newer almost one size fits all electric units that show up everywhere on the cheap and are supposed to provide UP TO about 5 pounds more boost for under 300 bucks,although i feel theres a good chance youd probably have to run two to get anywhere as from what i have heard but not confirmed they seem to overheat easy and so would probably have to toggle between the two if it were for anything more than an occasional straight stretch but would be without turbo lag or any parasitic effect turbo guys always argue traditional chargers have(think they may be jealous)and also have no idea how much power(whoops electricity is what i meant my bad,power here is usually measured in lb ft or hp)they drain,and if so what additional upgrades would be required to run it effectively in that regard as well short of a complete output upsizing or running duel diesel cells interested in knowing if its a sign of things to come or just some gimmick.
well can sorta answer my own question at least looked into it a bit more and would probably have to run two simultaneously on anything above 5.0 liters to get the power output desired anyway,and yeah looks like they do heat up too quickly for my taste and if wired to a heat sensor,could result in a loss of power when is inconvenient,so dont think the tech is where it needs to be yet to be considered on anything other than imports or domestic ffs other than maybe on a pre 87 brick nosed mustang you can still get on the cheap,and wouldn't feel bad about rigging up as a cost effective runner. although if you were to run three of them.......you may as well just get a turbo for the money at this point although a triple bank of electric snails would look pretty cool(0r 4).and i suppose if cooldown time was minimal or could be augmented by an electric fan and or addition of cooling fins could rig it so one or more was always on. at this point would you consider it a hybrid?
Do you want a blower with a carb which will stick through the hood or a blower with EFI that stays under the hood? Paul
There are ways to setup a blower on a stock intake: http://www.v8buick.com/showthread.php?142707-budget-blower-for-a-350-buick&highlight=blower Better yet a Procharger, here is a 600+ hp Buick 350: http://www.youtube.com/watch?v=zktYYQhCtqU Or in my mind even better is a trubocharged Buick 350: http://www.youtube.com/watch?v=UgEdT2jdkd8&feature=endscreen&NR=1 http://www.youtube.com/watch?v=XLRfK6l-aRc
Yea im pretty set on going with the carb blower kit, ive had my mind set on this for about a year. im really glad that i could possibly find the blower for 450 bucks cuz when i was looking supercharger usa i was cringing at the prices
No i don't have it....i don't have the money but i was looking at the blower kits from supercharger USA and was not sure if they could be hooked up to the old Buick 350's.
Don Hampton will most likely be building a 350 supercharger intake for me this winter. He built our 6-71 Nailhead SFI intake for our Nitro Nailhead dragster. I can see what it will cost if you want? This won't be until some time in January though.
Yea ill take a price on it. Im trying to figure out my whole budget out in the next few months so i get stuff done and get the car on the road.
I have a procharger on my 455. I run 5-7 psi boost, and it is a handfull:3gears: I am using a powerjection 3 throttle body fuel injection too. This makes tuning a lot easier.
There is plenty of room. Main concern is no power steering. I will figure that one out. When this drivetrain goes in my other can it will get A/C too. The whole combo is really coming together. I have a 2004R trans in there too. Nice to drive with a lockup converter and all. Mileage has probably tripled since I first got the car.:Brow:
yea i was thinking about a 455 swap in there. Power Steering might be an issue. But A/C i dont that thats what windows are for. ---------- Post added at 10:53 PM ---------- Previous post was at 10:50 PM ---------- I know a lot of guys boost their Buick's. I'm not looking to turbo it....Sorry guys who put a turbo on...no disrespect. But if i could here from guys who supercharged their motors it would be much appreciated.
Regarding your request for more discussion and info on supercharged Buicks, I have a bored 1970 Stage 1 455 (481) with a Hampton 8.71 blower. It is set up now with 8 psi boost. I'll attach a couple of photos if the attachment works. I had more boost originally but blew a piston top, even with 8.5 CR. Now have stronger Diamond forged billet pistons of 8.3 CR (custom) and cut the boost back to about 8 psi. Don Hampton built a Buick supercharger intake manifold for me in about 6-7 weeks. It looks and works great. See photo. I run two Edelbrock 750s and a TA roller cam with a supercharger grind (extended exhaust). Dave Harrington Troy, MI
So your supercharger just bolted on or you had to get that intake manifold custom made to fit the supercharger you wanted?
It was a Hampton kit with 8.71 blower, intake, crank and blower drive pulley set, top mounting plate for carburetors, tensioner and belt, but the intake configuration geometry is standardized for the roots-type blowers. All of these blowers in the series were originally designed as scavengers on big, stationary Detroit Diesel engines, with one blower per cylinder. The blower outlet ports location, gasket and 8-bolt mounting locations are the same for 6.71 and 8.71 blower designs, and are the same even for 4.71 and 10.71 blowers I believe. You should be able to get a roots blower from one source, and a manifold from another. (If you had to for some odd reason). If you are truly interested in setting up a roots blower on your engine, there are some important considerations that I will list. (Some of these I learned the hard way)! For purchasing a kit, your usual options are 6.71 or 8.71, rebuilt blower or new, natural, chrome or polished chrome finish and belt-tooth and pulley spacing (1/2 inch or 8 mm). For fuel control, the usual decisions that you will have to make will usually be Carter or Edelbrock, double or single pumper, one or two 4-barrels, and electric or manual choke. A fuel injection system (Hillborn or other) is usually not practical unless you have a really big budget. When you get your carburetors, also get the A/F metering adjustment kit for each one at the same time, as you will want to play with jets, springs and metering rods to optimize the performance. I would also recommend a wide-band A/F meter. Regarding throttle control, you will also need a complex throttle linkage lever system to operate the elevated carburetors. Such a linkage is readily available for either linear or side throttles, but will set you back another $170. An adjustable, progressive throttle control is recommended, and will cost you about another $70. If you have an MSD ignition system you will need a 2-bar or 3-bar MAP sensor also (2 bar if under 15 pounds boost). Finally, you will generally need a long but not wide air cleaner (that will fit through a reasonable hole in your hood), and a hood modification. Its better to know all of this in advance of any blower purchase, because all of these necessary extras can surprise you and easily add up to $1600 more than you anticipated for the full blower kit. Believe me, it does. Dave Harrington Troy, Michigan
Thats a lot to take in Thank You, But when you buy the blower kit, i noticed they don't come with the top air catcher thing (i don't know what its called), they go where the air filter would be for the carb....i don't know if that just being placed over the air filter or just does just straight air into it. But where do you get those?
See my first engine photo (three replies above). That air cleaner with the three flapper valves is a good looking one, and is available from Summit racing. It was about $220 as I recall, and works with either one 4-bbl or two 4-bbl carburetors. It comes with two replaceable air filter elements inside, and you can also order washable, semi-permanent filter elements for it. There are many other air-inlet designs for supercharger carburetors that are available at racing supply companies. I listed a lot of considerations in my message above, but forgot one important one. If you are adding a supercharger to an existing engine, you will very likely have to replace the pistons. This is particularly true if the existing engine is using any CR over 8.5. Don't get cast pistons; get forged racing pistons and stay under 8.5 CR. Locating such pistons is a minor problem, as I found out. Most piston manufacturers have designs for their forged racing pistons that WILL NOT accommodate 8.0 to 8.5 CR, especially the lightweight ones. They are designed for 10.5 to 12.0 CR (even 12.5 to 13.0 in some cases). They can't give you enough piston dish volume to lower the CR to 8.3, which was my target. I needed 34 cc of piston dish volume, even with thick steel head gaskets. After many calls to piston manufacturers I found out that Diamond pistons can do it, but it is expensive. So, in general, add the cost and aggravation of rebuilding your engine with a new set of expensive custom pistons to the cost of all of the items I listed above. If you don't do the pistons up front you will regret it, as I did. As the old oil commercial said ... "you can pay me now, or pay me later". Later is even more money. David Harrington Troy, Michigan
