    The axle tramp this car had on semi slicks or street tyres was insane, the shock loading on the drivetrain must have been intense.
    I am 100% convinced that squishy drag tyres do less damage to drivetrain than axle tramp.

    The echo as well, on semi slicks it felt like the car was ripping itself to pieces. 
    On drag slicks it just felt like a CVT, but the wheels were spinning instead of gearbox guts.

    I'm not too worried about breaking stuff. If it breaks it breaks.

    One annoying thing.
    I'm just looking to get some clarification around tech inspection requirements.
    It seems that ethrottle is banned for drag racing tech rules unless it's factory fitted. 
    So that might prevent me from passing a tech inspection. 

    Are you planning on going faster than 11.0? Or do you want to avoid wof/reg but still run at street car events?

  2. 50mm turbosmart gate, turbo is a GT4082 which is just an oem scania truck turbo. apparently good for about 600hp

    i chose it because it was quite cheap compared to a "performance" turbo of similar size.

    turbo guy reckoned the exhaust side was a bit big and the comp side a bit small but it seems to work well. makes boost from about 2000rpm, full boost by 25-2700ish, i rev it to 6 and it doesnt drop off

    only downside was i had to make v band things to suit, as the downpipe is a scania specific part

    Noted, in my head it looked like the best flow option with priority to the turbo but able open the gate to release pressure.

    Will see what I can do ive built so it can be easily modified at least.....

    With what you see what would you do?

    Use one of these?

    Something like that would be better

     

    In my opinion (and I'm not a tuning whiz, it's just stuff I've done that hasn't caused any problems) wastegate flow is important, even more so on something that is going to run lower boost (as the gate is going to flow more) and might be a bit fragile or sensitive to boost spikes or fluctuations

  4. i dont think its meant to be serviceable, but there is 2 bungs which can be removed, and under those are 2 pistons with springs behind them, a circlip holds the piston in, which i couldnt get out of the non functioning one

    im not actually sure what it does, it appears to be a block to pair the LF and RR circuits together

    i think i might just delete it altogether and run front-rear split instead of diagonal and see what happens

  5. Brake bleeding.

    Daihatsu Mira, has a brake proportioning valve/splitter on the firewall. 

    Had brake imbalance problem, replaced wheel cylinders , still had problem, got second hand proportioning valve which when you blow air through was more even in what was coming out the rear ports 

    Fitted it, had a hard time bleeding it , now can't get any fluid to come out of the left rear ,pedal is good, not a blocked hose as I can crack a pipe at the hose or the  valve and nothing comes out 

     

    It's almost like it has a safety thing where if something happens a valve shuts or something? 

     

    Any ideas or anyone had similar issues? 

  6. you would probably get away with a straight thru muffler if the engine had a turbo , but an NA engine will need something better.

     

    go hang out at a boat ramp and when a tractor with a coby sticking up launches a boat, thats a good indication of what a non turbo 2L diesel would sound like
