I want to have something powerful enough that it can do everything I might ever need. So for that same 5-10 grand could I build an ETM that could perform close to that?
If you mean "perform" as far as CFM/Lift/Flow
ONLY as your benchmarks then, sure, but there are a lot of other intangibles when considering a home-built ETM's functionality.
Configuring and marrying all the components can be very challenging and time consuming.
Even if you accomplish getting it "roughed" together, there will usually be a sh!tload of tweaks and mods to get it to run reliably that you failed to consider.
The actual set-up, operation, and break-down of the unit will likely include many extra proprietary steps that are not necessary with most factory TM's.
Sure it can be done, but it's a lot more work than most think, and what I consider a big gamble.
I have yet to hear many, what I consider to be legitimate reasons to justify "Why" one would choose to try building one as opposed to buying a TM.
I should do it just to try it and then when it all sucks and doesn't work I'll get a truckmount. How's that?
That's all fine and dandy.............You go boy.
If you have the time and the coin to give it a go without major worries if it does not work out, then it will certainly be a learning experience at the least.
It has been said that one learns more from his failures than his successes.
I sure did.
