Garret GT2554R were ok with 1130cc but what turbo are V-Rod guys using with larger displacements and better flowing configurations. Small turbo has become to its limitations
It is Swedish MCXpress plenum. I think it is great too. There is possibility for two additional shower type injectors on the top. I am figuring out how to use them someday. Now they are plugged. There is integrated oil catch can in the front but air volume for intake is still good for equal cyl flow.Where'd you get/make that plenum!
Mukle beat me to it...looks like Kaarza's/etc. I am almost designing my own which is similar to Holy Moto's but with some fairly significant changes (and a feature no one else offers).Where'd you get/make that plenum!
biggest problem i have with trask and holymoto is the plenum size.
Like the TTS option for that that reason but criminy your's is prettiest ive seen in a while!
Can be. I'm just following my intuition here. However things are not so straightforward and the case is rather complex. Whole engine is built for turbocharging so I want to choose best turbo option for my application. Of course this can lead to ashes as well.I was always told the larger the compressor the longer the lag and less snappy down low. Along with slower spooling
How are you handling prevention of block shift with this much power? I know Kaarza went to the extremes with dowels/larger bolts/etc.....never heard if it really held up. Are you rebuilding every couple thousand miles?That will be seen. Old turbo was pretty ok with the stock displacement but with the sturdy good flowing 1357cc stroker it just came to its limitations. Compressor power band was relatively narrow compared to EFR's band and it was hard to stay in good operation region. New compressor should be now almost anti-stalling and there is enough top flow with the good effiency. These can be seen when comparing compressor maps. Have to realize this in real life too.
EFR 6258 ain't that big turbo yet so I am not very concerned that it is too big yet. It's design is just from the different planet when you compare parts like turbine wheel and aluminium chra on whole. Turbine is made of Gamma-Ti material weights half of the old one. I hope that this will help on low end awakening and lag which all turbos suffer in some extent.
If this turns out shitty I can always come back but building and testing things is part of this hobby. I do not buy things without chewing them a bit. Every day is hard way learning and I do not take this too seriously.
