Is this Interesting?

Fox body mustang with a flathead on turbos or charger... Bit out of round here.

The location of the inter-cooler appears to be behind the firewall

A little bit connected to this , we'll sort of . Has anyone tried the AMR500 supercharger on a flathead ? It's small , real small and only $180 , so I ordered one to try . I'll try to install on a stock 8ba or a 21 stud lb motor on the stand .
It should give about 3-5 lbs boost IF , repeat IF it works as advertised.
Interested if anyone else has tried .
Thanks

Does it come with ear plugs? (so you don't have to listen to the whining)

I looked at them and it says "1.0 to 2.2 liters". Since a stock 239 is 3.9 liters, that's about half what you would need. Plus, I would have to believe it takes more "push" to force-feed a liter of flathead than a liter of an overhead. I have a little experience with this, helping a friend who was trying to supercharge his golf kart with a high end battery-powered leaf blower.

Hell, I'd still try it though; the price is right. Let us know how it turns out

I've played a lot with all different makes . Once edelbrock came out with the forced induction set ups , it was a no brainier for ease and performance. I agree I'm on the low end but it's a basically stock engine and will be happy to fill the cyl completely instead of 60-75% , if I have to buy 2 it's still cheap . It has shipped and should be here in a week . To be continued....

interesting.

[Ggmac]

Get the plans ( in my head ) together . I'm getting a little excited about the possibility. If it doesn't add performance, no one will know when it's parked !

[Ggmac]

Just received the little compressor, nice . Now comes the fun .

Hoping this project goes well for you !
Some here want pictures, details and how to from you also. Well, maybe just me !

[Flathead]

I like blown Flatheads

[tubman]

Yep, I hope everything goes well. My apprehension is that the undersized blower will act like a restrictor plate on a NASCAR stock car.

Interesting that it claims you can get 10 lbs of boost.

Mini Roots style Supercharger AISIN AMR500

The AMR500 is a 500cc per revolution supercharger.
Works best on small displacement engines using the stock cam.
Producing anywhere from 5 to 10lbs of boost depending on pulley combo.
The direction of rotation is optional on this charger, so it can easily work with your VW engine.
The supercharger can be mounted in any orientation because of the self contained oiling.
Supercharger oil required. SHIPS EMPTY. Oil Capacity, 100ml. BBM Full Synthetic Supercharger oil preferred.
SHIPS WITH 72MM PULLEY

Do like the LS Chevy guys are doing. Get a big 'ol turbo and spool it up!

That turbo is very interesting! And what a price! How can they do that? The little AMR unit made me think for a short while, but this one has really go me going.

Not sure how they make them so cheap, but if you notice they list the sizes of the popular LS motors. The LS guys buy a lot of these cheap turbos and just replace them if they go bad, but I haven't heard of too many doing so.

Seems like a good way to help our flatheads flow while also giving it a boost.

[tubman]

I always thought that producing intake boost to increase output by further restricting an already restricted exhaust system is kinda like trying to lift yourself up by your shoelaces, but I guess it works.

I actually think I would rather deal with fabricating an exhaust system to facilitate one of these than adding more belts and pulleys.

Tim, do you know : do these require a "blow through" carb? Mounting the carb before the turbo sounds easier.

[Tim Ayers]

Not sure. Most LS guys still run EFI and blow the boost through the throttle body. They control the ECM to give it a "tune". My friend's last LS was a 6.0L and using E85, he got something like 850 hp at the rear tire.

On a flat head, I can't see why you couldn't do a 4 bbl blow through.

I'd be curious if progressive boost like a turbo gives you would help the flat head breath.

Heres my Two cents on the turbo idea.
Using a turbo on the Flathead in this application to run all out top speeds would not really be any better if the boost was progressive. If anything the progressive boost can create a huge problem by being lean in one RPM range and creating a rich situation in another RPM level. Running Lean is the killer when running a Flathead with a blower no matter if its a turbo or a roots type. Just going lean for a split second and the damage is done. Turning the turbo with the exhaust will create a restriction of exhaust flow thus increasing the super heating of the water taking place inside the block. This also will add to the danger of going lean. However things dont end there with the boost air pressure entering the carb inlet once the air pressure level goes above the fuel pump regulated pressure point the carb fuel bowls now filled with this air pressure will not allow the floats to drop to let the gas flow in and fill the empty bowls now you risk being lean in another way. To address this last issue the fuel pump/regulator system must be designed for the blow threw system. Going with a turbo turned by exhaust flow on a Flathead is not easy I know Phil Landry hes going in a different direction and is setting records along the way if it was easy everyone would do it. This combination is truly the best of what back yard hot rodding is all about. Now some may ask if i would try this idea and the answer is no. The supercharged class i run with the race car is a vintage class the rules do not allow the use of turbos,electric injectors or engine management systems.

Interesting. Didn't think about the spool up wait time creating a "cork" and heating the water jackets.

I wonder if you could make a two turbo (small lead in) and a larger, primary spool set up work. Some OHV use this to prevent lag.

I'd assume all the serious guys would have tried this before, so I'm just thinking out loud.

Really intrigued about this since it's "free" power, but I guess nothing is really free.
