Aluminum knowledge for ya:
The common aluminum plate used offshore is 7075-T4 (also known as 2024-T3), which has a tensile strength 48-47ksi. The standard USA aluminum plate is 7075-T6, which has a tensile strength of 73-77ksi. So if the manufacture is stating it’s a 7075 chassis more than likely its 7075-T4 as to a BCE that’s 7075-T6. Tensile strength numbers are from ThyssenKrupp (Copper & Brass) which I believe is where BCE gets his stock from.

It is advertised as T6... Yes, 2024 has similar traits but not as corrosion resistant. I still don't understand calling it Alclad. It's a bonded mixture of materials used in coatings.

"Alclad" is being referred to as a construction technique, but maybe we should more accurately refer as a "composite" aluminum structure, what the OE mugen chassis appears to be. The point I was making is that that this should not be viewed as a design flaw, but it does have performance characteristics that, at least in my view, are an asset.
"Alclad" was originally coined by the aluminum company Alcoa: when M&Ms and ice cream sandwich construction was the way to go for aircraft parts.

I actually know what Alclad is... I know a decent amount about materials, actually. Engineering school teaches a lot about materials.
I just wonder where the determination that the mugen chassis is alclad. It seems a lot of assumptions are being made. How can you visually look at a mugen chassis after it's anodized or ever before and tell it's been bonded with alclad?
I'm just curious.. not trying to cause pointless argument.
As far as I know... mugens chassis are just plain 7075-T6 with a hard anodized coat. I think it would be a huge waste of money to get Alclad 7075-T6. I've worked with 7075 and in our usage it would have pretty much no benefit that I am aware of. 7075 is corrosion resistant enough for our usage.

And do you think USA is the only country where you can get 7075 T6? Get real, you're not the centre of the world you know.
Do you even know what the T3, T6 etc stand for?

Not trying to have pointless argument either, just a pathetic attempt in defending the OE chassis.

Sorry but how can you compare 7075 and 2024? They are not the same alloy at all. Maybe depending on the heat treatment on each, they can have similar mechanical properties but that's it.

No, other countries can get 7075-T6 as well. I used the words "common" and "standard" loosely. Its just our USA material suppliers carry the 7075-T6 as a standard material on the floor ready to ship to us. Other countries that builds molds with our name/specs for us have a hard time getting the 7075-T6 material we request. Usually its a delay because they don't carry it as a standard on there floor.
T is the temper grade.

I think almost for a fact that the mbx7 will have a chassis made from ultimatium or utopium.
Now, on with the show

I tested the new option springs, 8.0 F and 8.25 R, and there was a noticeable difference.
Much more planted in the curves and easier to drive consistently.

that spurs my curiousity! Are there any rumors about an MBX7??
07-09-2011, 02:02 AM
NO, Mugen just updated the 6 why would they make a 7? The mbx6 is ganna be there only buggy for a long time i think. Because the chassis and spring kit all just came out and they have a 2011EU kit which includes all the updates.

I just bought a nova 21-4c today, my question is..... will that engine work with a RB Concepts 2045 tuned pipe?
I was running an RB B10, I was very happy with it, but it has 10+ gallons of fuel through it and needs to be rebuilt, I do plan on doing that shortly.
Any thoughts?
Thx,
Lucas

i ran my 21-4 with the 9901 pipe and 41021 header and had great power and fuel economy. the 9953 pipe works great with this engine as well. try it and see, if you are struggling to get 10 minutes a tank after the motor has fully broken in (1 gallon or so), then you need to change pipes.
