Muncie Posted August 24, 2019 Author Share Posted August 24, 2019 Yeah nah not this time i can't pop the tyre over the rim due to pocket bike wheels been made from some sort of aged cheese if i can find a split rim it will work The hub girdle thing will absolutely work too unfortunately the above chedder grade rim cracked trying to fit the pocket bike tyre to it so ive got another complete wheel on the way....... because i cant be fucked fitting tyres they really are a cunt to get on without damaging them or the rim. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted August 25, 2019 Author Share Posted August 25, 2019 Back to the turbo...... everything is sorted for this i thought bar the manifold until i tried actuating the wastegate/vane thing it needs a vacuum signal not pressure. Got me a bit stumped maybe drilling a second port on the other side of the can will make it work. Anyone got an electronic boost controller floating around the shed? Just realized i will need one. 1 Quote Link to comment Share on other sites More sharing options...
Truenotch Posted August 25, 2019 Share Posted August 25, 2019 Is that an older variable vane turbo from a diesel vehicle? I’m pretty sure they don’t use VV turbos on petrol vehicles normally because the combustion temps are too high and kill the vanes really quickly. It would suck to go through the hassle of adding an electronic boost controller and then have the turbo die quickly after... 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted August 26, 2019 Author Share Posted August 26, 2019 Yup its a vane turbo off a touareg cant see it getting cooked to quick longest ride it gets is 5 ks before its out of fuel. If it does die I'll parts bin something else on. 2 Quote Link to comment Share on other sites More sharing options...
a.craw4d Posted August 26, 2019 Share Posted August 26, 2019 Could you remove the wastegate and set it up with some threaded rod or a bolt that you adjust manually? 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted August 26, 2019 Share Posted August 26, 2019 Make it freeboost then on /off with central lock solenoid? Quote Link to comment Share on other sites More sharing options...

Might be the easiest thing to do then add an external wastegate at least then if the vanes seize...... no matter. Will see if adding a vacuum port to the actuator will work first be cool if i can get the variable vane set up to work. Quote Link to comment Share on other sites More sharing options...
Muncie Posted August 28, 2019 Author Share Posted August 28, 2019 Received replacement wheel last night fitted the new hub brace bolted it it all together then proceeded to spin the rim inside the tyre just trying to crawl away from a stop. Fuck sake..... rim survived fine but new tyre is garbage it looked cheap and poorly made might be time to give up on the pocket bike wheel combo. Have found a 10" pit bike wheel that would go in the gap as a bonus has correct sprocket out of box. Its $ though and i am severely keen to fit it to a go kart or something else really soon. 1 Quote Link to comment Share on other sites More sharing options...

Kimjon Posted August 30, 2019 Share Posted August 30, 2019 Have you seen this? https://trademe.nz/marketplace/toys-models/ride-on-toys/scooters/listing/2293747834 Looks a nicely set up unit. Pretty clean and well thought out ideas. Perhaps adopting some of these design elements could advance your build? 2 Quote Link to comment Share on other sites More sharing options...
Muncie Posted August 31, 2019 Author Share Posted August 31, 2019 Thats the exact brake setup and rear wheel ive got my eye on. (Actually on my watch list) Ive come up with 3 options 1 fit the 10" pit bike wheel hope it works 2 fit the pit bike wheel shunt the engine forward and fit a seat. 3 fit another pocket bike wheel swap the engines from this and my sons mobility scooter and do huge skids on that. I have a 4th option of a golf cart im working real hard to get my hands on. 2 Quote Link to comment Share on other sites More sharing options...
Muncie Posted September 9, 2019 Author Share Posted September 9, 2019 So currently this is at work in storage while i sort the stuff that keeps breaking and work out of town. Anyway did some more turbo stuff, So i took a punt thinking surely if i move the spring from one side of the diaphragm in the actuator to the other side it will move under pressure instead of vacuum. Sure enough it does but now how the hell do i seal it?? Im thinking of using 2.5" triclover flanges to remake the can so i can crack it open to change springs easily as this one might not be quite right now its getting a different signal. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 31, 2019 Author Share Posted October 31, 2019 Its alive..... been sitting at back of a shipping container at work waiting for my attention to fix the busted wheel. Turbo tubing has arrived. When i get some time will start on the manifold aircraft dude at work is porting heads for me. 3 Quote Link to comment Share on other sites More sharing options...
Muncie Posted November 1, 2019 Author Share Posted November 1, 2019 Will be welding the 2-1 collector on the turbo flange this weekend needs to be done with mig as our tig at work where I'll do the pipes is a bit better suited to light stuff. Going to be doing tuned length if possible like whats on there now but in stainless its 1" into 1 1/2" tube to keep the velocity of gases up right up till they smash into the turbine. Should be fun. 3 Quote Link to comment Share on other sites More sharing options...
Muncie Posted November 1, 2019 Author Share Posted November 1, 2019 Well thats the down pipe fizzed together guess i need to man up and get on to rest of pipes when possible at work. Got some cleaning up to do on this internal weld but thats this part finished turbo is all ready to be plugged in made the oil lines ages ago.

Muncie Posted November 8, 2019 Author Share Posted November 8, 2019 The wheel hub brace works a treat i have absolutely torture tested this thing the last 2 weeks! Probably clocked up 70-100 ks on it now on gravel and grass fitting a bigger fuel tank and will keep riding. Have changed throw on throttle as it was very on or off now is heaps better. 2 Quote Link to comment Share on other sites More sharing options...

Muncie Posted November 21, 2019 Author Share Posted November 21, 2019 That ring that slips over hub has done wonders holding it all together i did a massive burnout on it yesterday nothing is showing any signs of duress. 9 hours ago, SOHC said: I want a twin for my stretch bike, I am amazed your rear wheel hub lasted at all Saw one last night on a concrete saw sitting embedded in a traffic island just out of huntly must of jumped off a trailer. 2 Quote Link to comment Share on other sites More sharing options...
