I dont know much about blue printing I just know it will probably benefit me so i still have to do some homework on it.
Indeed. A lot of it will have to do with application, make sure you find a very good machinist. I was taught some interesting tricks in finding a good machinist for you from an old time racer who has dealt with a lot of builds.
- Make sure you find one that takes interest in your project, and what you're looking for in application
- Make sure his equipment is up to par, well maintained, even if it's old - maintenance and precision is the most important
- Keep in mind it's setting a specification - not a tolerance
- Make sure they are thorough! and i quote
In our measurements we always went to the tenth of a thou, i.e. 0.0001", and in balancing we always went to a tenth of a gram. By the way, measurements are done with dial bore gauges, micrometers and the ilk, not plastigage!!!
A lot of it will have to do with application. Is this going to be an engine that will run a lap or two and need some slop and forgiveness in the metal as it goes along? Is it going to be an engine that instead will do endurance races and go for long periods of time? Is it going to be an engine that will be revving high and need tight tolerances for it's specification and use to be able to consistently achieve those with accuracy?
Definitely do the homework on blueprinting because there is a lot more to it than just blueprinting. I was told by this fellow (and I trust his information very much so, he's not set me wrong so far, very knowledgeable fellow) that a lot of shops will just "blueprint it" and not ask a lot of questions. Later down the road you find out the tolerances inside for your specification weren't really designed for what you're looking for, and the engine isn't up to the efficiency you need it at for application. And that's what it comes down to, application.
Balancing will also play a HUGE part of your engine build. Of course as parts go to high rpms - the tendency to do things they shouldn't do to weight increases, lubrication changes, metal expands, and this is where the wear and tear happens. An engine should be balanced and blueprinted to the specification and application you are using it for. Make sure you do your homework for it, then find a machinist you trust to do the work who takes interest /in your application/ and go from there.
Hope this helps. I'm in the process of finding one to do the balance and blueprinting on one of my Porsche motors. So far I've yet to find "that machinist" to do the work. I may end up having to travel for it for sure.
As to the high revs thing... you get into application again. Keep in mind a different engine for a different build. If the power and the way your engine makes torque is at a specific point and that works, then that's fine. But it doesn't mean it's preferable for every engine. I'm building mine for a mid range of rpms for my engine because of the way these engines run. Specifically, I'll be building it for a specific set of tracks and applications, therefore I don't need to rev high, but need a good midrange torque to pull me out of corners with my specific application and rarely will approach over 5500pm with my engine.
On the other hand with a different car, different type of power, I may need a different range to operate at. So keep in mind the statement of always wanting to be in high rpms will completely vary from application to application, which is what we are discussing here.
born2xlzx2 - also keep in mind such talk of spending such money on these vehicles is mostly unheard of, etc etc... so of course many people are likely to flick you crap and shoot you flak till motion is brought forth from statements. So don't take it personally when people question it. But indeed some of the statements are a bit confusing since you are talking about some of these mods
but also state you don't fully understand how some of it works, just keep in mind it's all a learning experience to take in and at some point we all learn
There is nothing wrong with that. At least you're willing to admit you don't understand some of it, this shows you're willing to put that out there and soak in info, which having an open mind about these things is EXACTLY how you learn about them.
But let's keep the tension to a minimum fellas. No one minds a good discussion about things, but we try to keep it tight knit over here, don't let it become an argument. I would rather see our members here learn from each other, than have a bitter feel towards each other. You learn so much more that way
Good luck with your build, born2xlzx2. I'll look forward to it's completion.
