Hey guys
I've just stumbled accross this site and i must say it looks like exactly what i've been looking for.I've been looking for information on building a basic flow bench that i could use to tune heads for my mini (A series engine).Thing is because i'm very new to this if anyone could direct me to an absolute laymans guide it would really help, preferably with diagrams.I did read a bit about the basic principles in your old forum archive but having never even seen a flow bench i found it kinda dificult to picture.Only other thing is i'm in england so if anyone has any experiences with dealing with supliers over here i'd really like to hear about them.
Cheers SJ

Hi,

I'm also in the UK.

Your best starting point is www.superflow.com superflow are the most well known flowbench manufacturer and their website has loads of information and pictures.

Their are also several published articles which give step by step guides to building flowbenches - I will provide a link for them later.

Your best bet is to do loads of research and really try to understand what the flowbench is and how it works. From there you will need to decide what type of bench you want and how powerful it needs to be. One of the most well known homebuilt benches is the MSD bench (which I will provide a link for later), many people have started their benches based on this design. However, this bench is very powerful (unnecessarily so in my opinion).

The most popular and common bench (used by the majority of race engine preparation companies is the Superflow 110 (I have seen these used on indy v8 heads as recent as 2 years ago). This bench is far smaller (and therefore cheaper to build and run) than the MSD bench. I am basing my design on this bench.

Good luck.

Hey guys,
Right after much reading i think i've got a decent idea how this all works for intake testing but how does exhaust testing work do you just reverse the blower motors and switch the lines around on the mamometer?
and does anyone know of a decent place to get vac motors in the UK.

[color=#000000]I've been buying dyson vac motors on ebay for about

[Speed_junkie]

I just looked on ebay and the specs of the motors are in airwatts how would i go about working out how much power i needed? is there anyway i can convert this into cfm.Also would dyson/any vacuum cleaner motor be suitable for testing both inlet and exhaust flow.
Cheers SJ

Far too technical for me...

I just assumed that dyson (being one of the most reputable vacuum manufacturers) would use good quality, powerful motors so I bought 2 motors which are used on the dyson DC01 model.

Ametek are a reputable motor manufacturer, so perhaps try searching for "dyson ametek" and see what you find.

hey guys
Just incase anyone else was wondering i've found out 1 airwatt is equvelent to 1 CFM.

p.s Jsmith if u find the dyson website it has all the specs on it for the different dyson motors so u will now be able to tell wot the flow capsity of your motors will be.
