Use A 420 Megablower

[Gr8ScatFan]

If you have around 3000 dollars or more you could have a 420 Megablower setup. It is better than a street 8-71 or the Holley 144 Powercharger. It is just as much as the other good ones. If you have a fully done Buick engine that is bored and stroked to the maximun with the highest horsepower possible for just the engine and want to have a complete racing engine that will put your GS in the low 8's high 7's this setup is the way to go. It can make around 800 horsepower on most engine including the Buick engine. But you need to invest the time and money in the blower and engine to get it up to 535 cubic inches and send it away to get built up. Earick Racing Engines and TA Performance will do these things. Earick had associations with Gary Paine and his race car Great Scat and TA Performance has a good reputation for their work. You can see all the cars they have had associations with on their website www.taperformance.com. Some names include Jim Weise and everyone knows Mike Tomazewski with his 9 second wagon. I hope this has helped people a bit with their racing engine and if you get it up and runnig take it down to the Nats.

[BlownNailhead]

So what is the point?

Slow down and think about what you write.........

[Gr8ScatFan]

Okay this one will be clear. This is more of a recipe for a very powerful Buick engine. But however its more for someone who can spend money on having a Buick with such power. Rod Hendrickson has the silver Skyhawk with the blower on it. It's best time to date is 8.16. I believe it uses the street version of the 6-71 on its engine. Now since this is the Racing Engine forum I'm assuming that many people here want a good engine. The first step for the 7 second Buick engine is to bore and stroke the engine. The biggest Buick engine is a 535 which is pretty good. But if you can get your engine to that step at a low compression you are ready for the next step. Again this is more for millionaires than an average person. A 420 Megablower setup is a very effective setup capable of making 800 horsepower. As far as I know only one big block Buick engine has ever been in the 7's which was in Scotty Guadagno's 88 Regal. But this setup will put a Buick in the 7's if nothing fails. You can find the blower in the Jeg's catalogue. For this it might be good to have someone else do it. I hope this post was more clear than the other one up there. If it didn't make any sense just reply and I'll try to clear it up a bit.

That's some good info and I thank you, but if people knew who they were speaking to, they may be more inclined to reply. We like to keep things personable here so most folks post their signature. Thanks

[gotbuick]

You are talking about BLOWERS and your a FAN of those racers you posted. Mmmmm, I can feel the breeze...:o

[dpcp66]

I have been putting a blower motor(6-71) together for my brother and the intake is the key. The blower you talk about has adifferent manifold then that of a 6-71 or bigger. Guys like BDS and Hampton have intakes that are not custom made for the motor. The are cast just like a performer or a SP1,etc. The 420 mega blower would require a custome bilt blower and pully system. That means the price is over $3000. The blower my brother and I are into is a 6-71 and a complete kit from hampton was only $3500 complete ready to ship. He reallt wanted a 142 blower and NOS on the car. But ran into the problem I just mentioned. So we found a rebuilt 6-71 and plan to buy the rest of the kit from Hampton.I still thing adding a power adder like a blower,NOS,turbo is the best way to get low ets in our Buicks. The idea of doing it naturally asperated is a great idea but to run some one that has a power adder and for us not is more often then not a loosing race from the start. I have raced guys with power adders and won. So its a cool feeling to beat someone without using it when they are. But when it comes time to race a guy that you might need a power adder for and you have one. It makes the out come something to watch. Not to mention it makes for a cool kill story. Man I wrote way to much down.

Nitrous is cheaper and faster, until the bottle is empty:Dou:

Roots-style blowers are cool, if you don't mind cutting a HUGE hole in your hood. they are also notoriously inefficient.

Belt-driven centrifugal type superchargers are much more efficient, and they fit under the hood! They also allow intercooling :Brow: :TU:

When it comes to real boost though, turbo(s) are the S**t!:jd:

That's the boat I'm in :Brow:

I used to think Turbos made the best HP boost wise too, until HotRod's test last month. The compaired the roots, Centrifical, and a Turbo setup all on the same motor. Nothing changed except for the power adder........... And to my suprise, the Centrifical made the most HP. All of them were ran at the same boost level too. It was a really good read. If you have a chance, check it out.

[grant455gs]

I was trying to goad you into responding here Rich!!:Brow: :Brow: :laugh: :laugh:

Yes I read that Hod Rod also:bglasses:

I still think turbos put out more hp for the boost.. I wonder if that article is part of a conspiracy to sell more centrifugals:Do No: :laugh:

No honestly I have always been impressed with centrifugals, always wanted to put one on my Buick, you just beat me to it Rich!:spank: TOO MANY REASONS!!

P.S. Rich, QUIT trying to lower your boost :spank: :spank:, and make it work with the 8-10 psi!!:TU: :TU: :TU: :TU:

Hi Steve !! Welcome to the V8Board

I think its cool that a 14 yr old like yourself is into Buick Power and knows his way around the motor compartment and who the fast guys are and have been.....Nice job on the homework:TU:

I've been to the Nats a few times too and always enjoy watching the "Big Dawgs" run the fast cars. That Supercharged Skyhawk is KILLER !! Its got the nasty-ist sounding idle I've ever heard....not to mention its song all wound out at the end of the track !!

The guys here are pretty much at the forefront of trying to - and succeeding in Supercharging and Turbocharging the Big Block Buick - and only bigger things to come will result from their effort.

Its still not very popular - not only due to cost, but also because there has never been a "Bolt On" kit offered by any vendor - with all the pieces needed to make either type of X-charging work, out of the box.

There is also issues with the block itself. Its only "so" strong and the guys that already making 740-850 HP would blow up their motors by trying to apply another 200-400 HP by using a "Power Adder"

In just alittle more time this will be taken care of as 2 different vendors will be offering Replacement Blocks that are brand new, Beefier than the 30+ year old originals and capable of taking whatever anyone can throw at them.

This will be an amazing thing to watch as things never before capable will start to be done for the first time. Its only a matter of 1 or 2 years before 1,000 HP V8Buicks will be pounding the dragstrips......

Its going to be AWSOME !!

Indeed!!:TU: Hopefully not quite that long though.. and the 1,000 hp, that will be without power adders!:Brow: :grin:

Hey Grant,

Believe me, If I had a 8.5 or 9 to 1 motor, with a girdle and aftermarket rods, I'd leave it at 8 to 10 psi in a heart beat. At this point I'm just trying to go as quickly as possible with the current configuration on "Pump Gas".

I can't wait until I have something that will allow 12 to 15 psi :Brow: This motor just isn't it unless I want to pick up the pieces after a run :(

[Gr8ScatFan]

Thanks 69GS400. I have learned a lot about the Buick 231 Turbocharged engine and the other day my dad bought a 455 to put in a Skyhawk so now I can learn more about it. I can only credit most of the stuff I know to reading the GS Xtras and the other books plus down at the Nats I'll talk with some people about their secrets with the big block Buick. I never realized that the 420 would require a different manifold. I guess just a huge motor and some NOS would work or a 231 with a turbo. My dad owns a GN and his combo is working good. But this is V8buick.com so it should be mostly about the big blocks, like this one.

Steve

[69GS400s]

Steve - I saw the wagon do that several times !!

Next to watching the Space Shuttle liftoff, its about the most exciting thing I've ever seen :bglasses:

In later years, Mike T. - owner of that 68 Special wagon and also owner of T.A. Performance - tamed down the wagons' launches by using , i believe, a Jericho transmission. The Wagon went faster but those bumper-standing launches were gone.

I Asked Mike once what it was like sitting in the Wagon when he put the nose to the sky ( I did alittle math and calculated his head to be over 7 feet in the air !!!). He said it was both thrilling and scarry at the same time - He cant really see where he's going for a few seconds and looks out the side windows to judge if the wagon is launching straight down the track !!!

Rumor has it the Wagon may make a rare appearance at the Buick Performance Groups' National event next August !!

I'll be there with PLENTY of Video Tape in my Camera !!

[Boozoo]

If I remember reading that one correctly, the particular roots they chose wasn't capable of running the same boost as the other test candidates which hurt its results.

I always thought the roots has its place where it dominates, but primarily that place is on a serious bad-ass drag racer. Am I far off? :Do No:

[grant455gs]

Most if not all of the FAST "doorslamers" have moved away from roots blowers and even nitrous to some degree. They choose centrifugal blowers or turbo(s), leaning more towards turbos it seems.

True, they didn't pick a fair comparo for the rootsblower. I think it made 8psi, where turbo and centrifugal were at 9.5.

There's nothing wrong with centrifugal blowers and I always anxiously await updates of your blower set-up, but I just want to point out that the centrifugal made the most PEAK power. Specifically, it made the most power from 5700 to the 6000 rpm redline (and granted, was still climbing). However, the turbo made the most power from 2500 - 5700 rpm. Plus, from about 3000 - 5000 rpm, the turbo made quite a bit more power than both the centrifugal and the roots blowers.

[John Eberly]

The real mistake in that article was that they "left off" the turbo intercooler to "make it fair".

In other words, the complete turbo/intercooler package would have made more power than either of the blowers.

I've just let my Hot Rod subscription lapse. I'm tired of that and other rags being written by a bunch of idiots with all kinds of excuses about why the dyno was too expensive or the torque converter stalled too high or whatever. I guess I'm getting too old, but I miss the "Old Days" when the magazines were worth keeping for reference.

I think that Hot Rod is about to repeat their "van phase" next anyway and I don't need to see that. I will miss Marlan though...

Yes, the Turbo would have made more power with a intercooler. For that matter, so would the Centrifical Charger (alot more). Would the turbo had made more... probably.

Don't get me wrong, I love turbos. The only down fall about them to me, is all the excessive under hood heat, ducting, and haveing to run a oil line to the turbo.

Anyway you look at it, boost is just plain cool no matter what's making it. :beer

Don't forget COST!!:Dou:

Roots-style will always be eye-candy..

Turbos are probably the best boost..

Centrifugals are cheap, easy, and making HUGE STRIDES towards BEATING turbos!!

But Rich, your still right!! any boost is :bglasses: with me!:TU: :TU:

[afracer]

Yeah, I can't wait to see what people will be able to do with the new blocks and some forced induction, I think 1500 horsepower+ should be possible with some massive twin turbos and intercooling, at least I would hope so! I am currently in Japan (military serving overseas) and I desperately miss my BBB Sport Wagon and American muscle....but these frickin Nissan Skyline GTR's over here are ridiculous, the done up ones are usually at or above the 1000 hp mark. I got a video off the net of one doing a dyno run at ~1000 hp...it's INSANE when the boost comes on cause when he starts up and runs up to 4th gear, it sounds like he's getting on it....then it holds at like 4000 rpm or so and THEN the dude opens it up, HOLY crap that's a lot of boost. Love that sound though. The best part is two guys(idiots) sitting on the rear of the car while it's doing this to keep traction, I don't think you could pay me to do that, but I guess ricers will be ricers! Well point I'm getting to is, if they can get 1000 hp out of a ~2.6 liter inline 6 cylinder, and Buick v-6's can get even more than that....I'm anxious to see what a mega blown/built 455 would do! The scary part about these Skylines is that they're stinkin everywhere in at least mild tune (400+hp), and there's no telling just how fast it's gonna be. Hopefully I'll be able to run with them soon, I'm putting an SR20DET (2L DOHC Turbo) into my 1500 lb Datsun, they run 205 hp stock.

Enough ricer talk....I miss my Wagon. It was on the verge of 13's when I left it in my parent's care in June. Can't wait to throw a posi and Almn. Stg 1 heads on when I return!

[Nitro71455]

Although I've been working on lowering my CP, I'll still be stuck with 5 to 8 psi......... with this motor anyway. Even at that, it's pushing the stock rods pretty good. :(

[grant455gs]

I hear ya Rich..:o You planning on some TA Sportsman rods and new pistons anytime soon? Are you just trying to get the car up and running at Vegas, or are you gunna keep it together for awhile?

grant455gs said:I hear ya Rich..:o You planning on some TA Sportsman rods and new pistons anytime soon? Are you just trying to get the car up and running at Vegas, or are you gunna keep it together for awhile?

Well.... I really don't want to invest anymore into this motor than I alreay have :). I'm hoping that this will last until I can get a new block to start building (slowly). I suppose I could have invested another 7 hundred plus some $ for balancing the asymbly again as well as having the new rods pressed on (ok say 900.00 with it all said and done)....... but my wife is already not too happy about the 900.00 bucks for machine work, rings, cam, lifters, and bearnings.... that I spent last week :o

Anyway, I think not pushing anymore than 8psi as well as setting the REV limmiter down from 6000 to 5600 will help the rods live a long life. We will most deffenatly find out :grin:

That much? I thought it was only 1500 or something. Anyways on turbobuick.com I read that someone had 1600 horsepower in their GN. It was someone I had never heard of before.
