Centrifugal supercharger kits soon

[Mike T]

OK here it goes...

I have begun developing centrifugal supercharger kits for Buick 350 & 400/430/455 engines. I hope to have the first prototype kit available by the GSCA Nationals.

Since many of you have inquired, turbo kits are available as well.

I hope to have more information, possibly website available soon.

Will you be using any of the ATI Procharger models??

I think intercooled boost is the only way to go!!

I just read this after my other post. Are you going to take the fun out of me making a turbo setup for my Buick? Well, nuts. I can't wait to see what you have in store.

[Mike T]

I am using ATI supercharger units.

AZ, didn't mean to spoil any "fun"!

Potential delivery at the nationals?

Be sure to posts some pictures as you progress....

hmmm how much boost can be run at 10:1 compression with TA aluminum heads? Or how do I get the compression down without a new engine? something to think about during those boring moments

[Insane Buick]

I'm pretty sure you can just throw some thnking head gaskets and that will lower you compression, depending on the thickness. Other than that i'm not really sure that there is a way other than changing pistons...:Do No:

[Adam Whitman]

So how thick of copper head-gaskets can be had? .125" ?:puzzled:

[Mike T]

Adam,

With the proper size intercooler, we can set you up with about 10-14 lbs of boost. I would feel more comfortable with 10 psi with that high of a compression ratio.

First though, are you absolutely sure about your compression ratio? Are you using forged pistons? Have you decked the motor or milled the head?

The aluminum head should give you a little margin of safety to run that level of boost without detonation. This is of course a rule of thumb only as every engine is different and there are a great number of factors involved.

*website coming soon

[Adam Whitman]

Yep, after doing 2 "budget" engines in a row and ending up with dismal compression ratios (damned raised piston-pin height was the biggest reason), the last 2 were carefully planned.


Speed-pro pistons @0.005" deck-height, milled (current) iron heads 0.030" to get to 65cc, and 0.040" extra stroke didn't hurt either :grin: 10.2:1 +/- a cc or 2. I could prolly get it down to about 9.5 with some chamber-hogging and thicker gaskets, or the '71 heads I have in the shed even if I don't go the aluminum route. that should give me at least 10-15 more cc without much headache.

Looking forward to some pictures!

[Mike T]

Adam,

That's some pretty stout compression to be sure. If you haven't already unshrouded the valves (if they are Stage 1), unshrouding will help a little. Luckily, with the benefits affording by using intercooled boost with a carburetor, it can be done.

It will be CRUCIAL that the fuel system is properly set up. We recommend an Aeromotive A1000 fuel pump, boost sensitive pressure regulator, 10 micron & 100 micron fuel filters, 1/2" fuel feed line & 1/2" (or larger!) return line, and , properly modified Holley 950HP for the correct fuel curve. Currently there is no other pump available other than Magnaflow (much more expensive) which is suitable. Fuel system is an option on the kit.

I recognize the importance of getting some pictures up, and desperately want to get that gone. Unfortunately, its going to be VERY difficult to do that before the Nats with development demands being what they are. Keep checking in.

Just an update.

Blower has been in for awhile, fuel system is trickling in (no pun intended).

Unfortunately, between this and recent illness I do not at this point see any way to have a prototype available at the Nationals. But we will try anyway:).

I have new e-mail address although website is still under development.

[Mike T]

First off, thanks to everyone who stopped to visit at the Nationals and talk about the supercharger system a little. I really enjoyed doing it and got to put at a lot of faces with names.

Next year we hope to have a much better display, possibly some parts and a least one car. We may even do an onsite installation.

I couple of you have pretty much stepped up & said that you are ready for the blower as soon as it is done. If I have your e-mail address, I will let you know when the website is up and also when the blower kits are finished.

If you have questions or want to place an order e-mail us at the address below.

Thanks,

For everyone who didnt get to see Michael and his set up for the Big Blocks.. you missed out on a new venture for the Buick v8s
It looked to be one setup that surely will add some power .
Michael has came up with using a blower hat for the carb and recomended using a small spacer to counter against turbulence and recomended a carb company that will prep any Holley DP to be ran in Boost conditions.
I appeared that he had all the bases covered in my question department. Very Knowledgeable
It wasnt installed on anything but all was there but the brackets to bolt it to the eng..... a awsum set up!!!
Nice also to put a face with the name Mike... just wanted to know did ya buy that $1200 Regal to put your first blower motor in?:laugh:
Yep count me in on that list for one the first your marketing.:TU:
Later

[Mike T]

Well, we had a '70 Skylark to use as a project car, so I fiqured I needed the Regal like another hole in my head. Of course it didn't dawn on me until I got home that the Regal would make a FAR better candidate because it appeared to be in such great shape. I'll probably spend $1200 bucks just on sheetmetal for the '70.

Did anybody get the phone number off that car?

BTW, kits may be finished in as little as 30-60 days!

Mike - Just wanted to bump this back up top for you.:)

Looking forward to the kit being out. Going to make it much easier for us Buick guys!!:TU: :TU:

[Nitro71455]

Mike,

How much farther away are the kits? I wish I would have known your were at the nats. I would have loved to see what you had. Anyway, I'm ready to charge mine. How much will your kit be? What size of ProCharger will it include? Let me know ASAP.


Rich

[Nitro71455]

Update.

Talked with Mike. Hopefully a D1SC kit will be knocking on my door in about 3 weeks! :grin: :grin: :grin: Can't wait to feel the boost!!!

[Chris Robertson]

When? When??? How much???

[Nitro71455]

Well...... I'm still waiting for mine. I haven't heard anything from Mike in a few days, but hopefully it's ready in about 1 1/2 weeks. He's not certain on price yet, and it will depend on the size of the charger you go with.

Drop him a message and let him know what your combo is an how much performance you want out of the charger. He should then be able to give you somewhat of a price.

[russ]

What kind of motor buildup do you recommend for strength. I have a 72 nos complete short block. I feel the compression with 1970 heads should be ideal for this combo.Any input appreciated

[Nitro71455]

It looks like the kits have been delayed a bit. Mike has been busy with YearOne projects that were on a deadline. Anyway, he said they would hopefully be ready to go in about 3 to 4 weeks depending on the bracket manufactor getting there end done.

Russ, You should send a privit message to "Mike T" asking him about the details.

[Chris Robertson]

Are we close yet?? Will the kit have all the pulleys and brackets? Tell us more were waiting....

[Nitro71455]

Well.....

Here's the scoop. My charger is on the way (with out the brackets). Mike is running a bit behind the date he thought they would be ready due to over time at work. Hopefully the kits will be ready to go soooooooon.

The Kit's Mike T is selling will come as a Bolt on Kit! This will come with the brackets and Pulley with everything needed to bolt it onto a buick 455! The install time should be around 4 hours :grin: It is complete!!!!!

I should hopefully have my charger twards the end of next week and hopefully the brakets and pulleys will follow by a couple of weeks. I can't wait for the BOOOOST.

Rich

[Todd Borland]

Sounds great do you have any pictures and a prise yet.

[Nitro71455]

Hey Todd,

I don't have any pic's yet. I'm still waiting for my kit. The charger should be here this week. Hopefully the brackets will follow within the next couple weeks.

As for price, You should contact Mike T. I think he can give you a good cloes price now that the brackets are being made and he can but a dollar value on them. The price is also going to depend on the Charger you go with.

Mike a really nice guy, drop him a PV or a email.

Rich

[Nitro71455]

Well.... I got the Charger and piping from ATI today. Now all I need is Brakets from Mike.:) Hopefully they will be done very soon. Looking at the charger is making me very itchy to use it.:Brow:

[Nitro71455]

Well.... I'm still waiting on the brakets. Mike has been very busy latley.

[gs455david]

I have contacted Mike and received responses quite some time ago. I have yet to see anyone receive brackets. Will these brackets be a possibility or will fabrication from someone local be necessary. I have an F1 kit ready to go and that is it. Is there anyone reputable that responds to emails and can get the job done?

[Nitro71455]

Hey David,

I beleive Mike will get the brackets done. It just a matter of time. When I talked to him a month ago he talked like the basic brackets were mached up and they just needed to be improved for durability. He was then hit by dead lines at YearOne that pulled him off the project.

Hopefully now that that done, he will get the brackets hammered out.

[Stg1Regal]

I remember an article from awhile back, about an ATI Procharger installed on a Mopar 360.
Now ATI didn't do this install or have a kit availible.
The author of the article did the install by fabbing his own bracket.
He started by taking 2 pieces of angle iron and mounting it to 2 of the bolts that help the water pump /timing cover down.
He then angeled those 2 pieces of angle iron over to the pass side head, trimmed them down to mount the charger.
The charger location was then just in front of and just a little bit higher that the valve cover.
Then he designed a template using cardboard, at that time adding more holes for mounting in the timing cover/ water pump area and more mount holes for the charger.
He then designed the form of the bracket and cut it out and took it a a metal fabrication shop and had the designed bracket machined out of a thick flat piece of aluminum.
Once mounted to the engine some spacers where added between the head and the back of the plate for support.
A slotted bracket was also made with a pulley on top for a tensioner, it was held in place with 2 large bolts.
Now this set up was ran by itself, with no accessories.....so that would be taken in consideration.
As for a crank hub pulley for the charger , that fits a Buick 455, that's another story , I don't how one would go about fabbing that, or if one is availible aftermarket.
It looked fairly easy to make......
I did a rough drawing of what I remember what the bracket looks like , maybe it will spark an Idea of sorts.

[Stg1Regal]

I have been playing around with an idea of mine regarding this same subject.
I was just thinking about using all the bracketry and accessories from my Grand National serpentine belt drive set up.
The condensor the A/C piping and hoses and the Pwr steering pump and Resivor.
I thought about using that set up on the the 455 as a serpentine belt drive system.
Not sure if the Alternator will clear the H.E.I. tho .
I have all of it removed from the GN just havn't had the time to try it yet, but I figured if the N/A bracketry works this should also.
(I'M HOPING):rolleyes:
This completely frees up the Pass side head to mount a ProCharger.
Later

[Nitro71455]

It's a very good thought, but I would be VERY lerry about mounding anything to our "waterpump / Timing cover". This is a very weak spot on the motor and IMO should be avioded.

It would be WAY sweet if you could use the GN's accessories to free up the passengers side. That would make the install alot easier for sure.

[GS69350]

What about going manual steering and using the driver's side head where no accessories are in the first place? Wouldn't that be a logical place to mount another belt drive accessory?? Nothing else in the way...

[GSXMEN]

I think you could keep the power steering, but it would certainly help to convert to a remote reservoir! That would take up very little room compared to the normal unit.

[Bill Lankford]

Nitro71455,

Heard anything from Mike T. latley?


Bill

[Nitro71455]

Hey Bill....

I have actually. Mike's been very good at keeping me in the loop on what's going on. He's had a couple of failed attemps on the 455 braket (wouldn't fit under the hood). I taked to him last Thursday adn it sounded like the 350 braket was a go (just needed to be machined) and the new redesined 455 braket should be right behind it (it's a little toughter to test since he doesn't have a 455 skylark/gs on hand to test). Anyway, it sounded like good positive progress is finally being made. Mike has really had a stroke of bad luck on the brakets.

[Bill Lankford]

Hi Rich,

Thanks for the reply. I`m getting a little antsy waiting. Sure would be nice to have something by BG.

Bill

[DaProblemChild]

I talked to you at Nats last year about my hood clearance problem, and I was just wondering if you had investigaded this at all as far as measurements were concerned. I broke the motor in my GS so i swapped in the one out of my Camaro and am thinking about building a 540 to go in it's place. I should have the manual trans swap done soon, and I want to get this thing back on the road. If the blower will fit sign me up. Let me know. Thanks, Chris
