Turbo crank?

[dizasterzrfun69]

What exactly is a turbo crank? Is it just a lightened crank? would this be a good add on to a 310r? Who can do it?....Ronnie?

Its Veins cut in the crank....some say it works......most dont.....ronnies version is a little diffrent, has like a Machined Rough surface to it.

it worked for me on my old 89 q-racer

[dizasterzrfun69]

well does it lighten the crank or what? it seems like a couple small scratches in the crank wouldnt do much good for anything.

All of the "turbo" cranks I've ever seen had a knurled finish on the outside of the flywieght's surface. It's supposed to create a turbulance or "turbo" effect on the intake charge in the lower end. Does it work ?? I don't know. Doesn't make the crank any lighter.

my turboed crank and nathens crank

does this really work, looks like a lot of work for little gain... with what the increase for this do you know?

my turboed crank and nathens crank
Nathans crank look like it might seriously work.Do you have any information on it ?Thanks

[dizasterzrfun69]

so now for the ultimate question. Is it worth messing with? and how much does ronnie charge to do one?

[Bryan Raffa]

you need to contact him he does the one on the left that knerled(sp)

It mixes the the gas and air thats in the case for a better burn(turbo effect), thus creating more hp, is the theory behind it.

[dizasterzrfun69]

well the bike already has to run 110 octane in it, think the turbo crank would give it more oomph or would it be a waste for this bike? The bike has an esr310 kit, some huge carb (not sure what it is), a +12 swinger, and an FTZ out of frame drag pipe.

[Billy Golightly]

I think that other one is actually the crank thats in Ronnies Z.

[Bryan Raffa]

it for shure is not going to hurt it at all!!!

[mnnmaz]

its alot of work for little increase dont you think? unless you wnat to do it for the fun if it....

[Bryan Raffa]

when ya build a drag bike every little bit helps, Just like removeing weight every little bit helps!!

[mnnmaz]

gotcha! maybe on the next build? Thanks for the info on all that!

Pretty sure you can't do that to a Honda Crank anyhow.

yea i just heard that :rolleyes: oh well it was worth a shot

[SWIGIN]

sure you can...iv seen turboed honda cranks before

[dizasterzrfun69]

sure you can...iv seen turboed honda cranks before


Well i guess you can but just barely because the honda 250r cranks have a coating/shell on them

From what I understand with the Turbo Crank it enables you to take off the flywheel weights for a higher rev,it also lets you have a better fuel disbursment from the bottom of the case equaling more fuel to the top end ! Port job and a valve system or bigger reed cage are advised from what I understand! Sounds like new inovation,don't know how long it's been around for at all! I don't know either if it can be done to a stock crank or what!

iv'e done the "shelled" ATC-TRX Crank's Before BUT......................
it's a VERY Light Knurl..... Not as GOOD of a Knurl as the one shown on the 490 Crank on Raffa's Motor ... it's "Risky" because iv'e seen the "shell" come apart before..... keep in mind........... the "ATC-TRX" Motor's are one of the BEST Motor's EVER Built .... do EVERYTHING Except the Turbo Crank ....
the "YAMI'S" Need it !! :lol: ........ The Honda Doesn't ......
