    Mike,
    Cannot swear to what size vacuum line I use for the boost reference. Same size that would go to the vac can for the heater/AC controls. Seems to work fine. Braided line erases all doubts about the line though.

    I need help from those of you that are using centrifugal superchargers.

    I'd like to know what you are using for timing for boost levels up to 10 lbs.
    I realize there are many variables such as compression ratio, type of head,
    intercoolers, fuel octane, carb, EFI, ect..
    If you don't mind including your combination or any other pertinent information it would help.

    Thanks in advance for the education

    What kind of ignation system do you have?

    Some systems have a "plug and play" type of timing control.

    I have my Mallory system set to 24 * total advance. It does fine with the aluminum heads.

    In this particular case the car is not mine. I'm just helping out.
    However I'd like to know more for future projects.

    Will be using an MSD 7531 with a 2 bar map sensor.
    There is also a water to air intercooler.
    It will be mainly drag racing.

    Thanks

    In the middle of a cam change right now. Finally putting in the Scott Brown custom.

    Here are the specs. 462, 9.5:1, Poston girdled pan, Iron stage 1's mild porting, 4" front mount intercooler, 650 Quickfuel BAN carb. D1 Procharger. 5to 7 pounds of boost. I run a Mallory distributor, 6al box with MSD boost contoller. Timing is 22* initial, 10* centrifical with no vacuum advance. The disadvatage of the MSD boost controller is that it is really a guess as to how much timing is being pulled our. My guess is that it likes about 24*to 26* total advance at 5 psi. WOT afr is about 11.4. Still sorting it out. (like that will ever end )

    We use our leak down tester to check all our Racepak pressure sensors and any other pressure device.

    Make up a set of fittings so you can attach your leak down tester to the manifold line that goes to the MSD boost control unit.
    Don't forget to plug the fitting in the intake manifold after the line is removed.

    With the regulator on the leak down tester turned completely off start the engine and adjust the rpm so all the mechanic advance is in.
    Then slowly apply pressure to the MSD boost control unit with the leak down tester till you get to 5 lbs and check the timing with a timing light.

    Let me know if this works for you.

    A cylinder leak down tester fills the cylinder with air through the spark plug hole and indicates what percentage of air is leaking out of the cylinder.
    Unlike a compression tester you can figure out where the air is going, rings, intake valve, exhaust valve or bubbles in the radiator coolant for a bad head gasket.

    Since it has an air regulator and gauges it can be used for testing many other devices.

    Every shop should have one!

    I hope this helps.

    I have been reading through this thread with much interest. I am starting to get the "Itch" to try some form of boost, but having zero experience in this area, I'm seeking counsel before doing something silly.

    I'm wondering if those of you who have "gone before" would care to comment (Pro or Con) on the current supercharger kits being offered by TA Performance? Good buy for the money? A reasonable bolt-on project for a moderately experienced shade-tree mechanic? My '70 Skylark still has the original 350ci engine (9.0 comp. ratio, factory 285 HP, engine code=SB), with about 90,000 miles and running perfectly. I have added a TA Stage 1 intake with a Holly 4-Bbl, and a Mallory Comp SS distributor and coil. The rest of the engine is still untouched factory stock original, except for normal external replacement service items (water pump, alternator, etc).

    My goal would be a very mild level of modification - I.E low boost levels on a mostly stock (internally) pump-gas engine, requiring few compromises when used in a street-driven weekend fun car. The TA 1220H-1 kit (P-1SC supercharger + water injection, list price $5750.00) would seem to be suited to this type of project. What would be the minimum preparation required before adding this kit to my engine? Could I get away with using the stock internals? Can you still run power steering and A/C with this kit installed? I realize I can call TA and ask these questions, but I thought I would solicit some opinions here before I bother those guys. If it looks like this project would be way too expensive or complicated for my limited (financial and mental) resources, I'll just forget all about it and go back to day-dreaming.

    Any and all advice/comments would be welcome. Thanks.

    I would not Run much boost with stock parts.

    Maybe three pounds at the most. Although with a 350, you may get away with five pounds.

    If I was you I would run a Twin Turbo Kit from Burton Machine. You can not run AC but you can run power steering with the turbo kit. There is supposed to be a single turbo kit coming out that will allow AC. I am currently adding this kit to a stock 70 Buick 350 like the one you have. All we added was ported heads, and a single plane intake the stock cam, pistons, etc are in place. This engine will be pushed on the street, dyno and track before the good Buick 350 is swapped in. I am using some thicker head gaskets to get the compression to about 8.6:1 down from 9:1.

    I see no reason why you can not boost 7 PSI to the stock engine, and if you did hurt the engine you could find another 350 that runs great for about $200 and then add some forged pistons... The only thing that really needs to be upgraded for higher boost on the Buick 350 is the pistons. At the 700+ HP range we are adding stronger connecting rods as well.

    Here is Jay and his car with the twin kit using a basically stock engine:

    http://www.v8buick.com/showthread.php?t=168371&page=16

    Here is mark Burton who builds the kits, he has been boosting a worn out stock 350 for years now:

    Sean,

    Thanks for taking the time to post a thoughtful reply to my question. I have read all about the twin turbo setups on this forum, and they are "more" of everything than I wish to pursue. All I want is something simple, that I can bolt on my existing engine in a weekend (ha, ha), and have it quickly running on the street without needing to be a Rocket Scientist. I don't need a race car, I just want a little more power than stock, and something that will look good when I pop the hood at cruise night. That's why I asked about the TA Performance blower kit. "Kit" implies easy install without a lot of parts chasing or custom fabrication. The water injection should help it run with pump gas and my stock compression. But since nobody has responded with any specific info about the TA supercharger kit, I must assume it has not attracted a lot of buyers. I have some other projects keeping me occupied at this time, so any mods to my Skylark are pretty much on hold. Meanwhile, I'll keep reading and educating myself on the options. Thanks again, Chuck Avery.

    I've been running on a bone stock shortblock since day one (about 6 years now) mostly at 8psi. I actually ran it on 87 octane with no intercooler for a while, but had to take a lot of timing out. it takes 28 degrees of timing on 8psi with no rattles or sputters on 92 octane. Pulls 20" of vacuum and cruises super mellow. I would not consider doing another car without turbos. Best of both worlds, smooth cruising, great power.

    Rick, I will for sure give you a call some time. I tried to look you up when I purchased the car but came up with a lot of dead ends. I burned the trans up at the GS Nationals this year but was going to replace it with a built 2004r out of a 9 second GN anyhow. Will also be adding fuel injection over the winter. Should be a real beast in the spring! Thanks for chiming in.

    I started at .038 . It ran alright until I upped the boost. At over eight pounds it started to blow out the flame and had to make it smaller.

    The engine likes 0.030 at 10 pounds of boost.

    I figure my Buick might fit here.
    1970 Skylark. I bought it with a Chev 350 in it; then replaced with a Blown 350, then a blown 406.... blew them both up.
    Bought a 455 for it a year ago, put a 4 speed in it... and it has an oil leak that was the result of fixing the low oil pressure issues it had.

    So... I'm building a new motor for it... and as I don't do well with the words stock, restoration, or reliable... here's what's coming

    462 Buick, forged Speed pro pistons
    Edelbrock aluminum heads
    stock crank, rods
    girdle
    custom TA performance roller cam
    twin GT 35 turbos
    Fuel injection - although I haven't decided which FI to run yet - leaning towards MS... but haven't bought it yet.
    I'll build my own sheet metal intake and headers for the turbos.

    expected HP is 700.

    let it rip!!!go all the way or dont do it at all..MS is great setup if you are good with programming and tunning yourself. this is a picture of the turbo headers i built.. if you need any advice i be glad to tell you where i made mistakes so you dont make the same. i built a set out of steel first and mounted and mocked up the turbos and than built the next set out of 304ss i am going to send them out to be coated but motor is apart for rebuild so that is on the back burner.
    best of luck
