    Hobbywing Max4 - EZRUN 70125 - Speedmaster P2 build

    The switch is a 3phase isolator I got out of the scrap bin. It isolates all 4 contacts so makes connecting the batteries a bit less sparky. Not sure if it will make it final install but it's nice and handy on the bench.

    Hi guys, Every time I load the site on chrome desktop avast flags a threat JS:Agent-EJP and blocks the rest of the site from loading. Not sure if it's a false positive or not?

    Hobbywing Max4 - EZRUN 70125 - Speedmaster P2 build

    Hey, progress has been slow actaully. Been struggling to get any time but some little bits happening. I've started to check positioning in the engine bay which looks ok actually. Started on a MAF sensor mount to be welded to a new intake pipe. Got a blow off valve to be welded to the same pipe...

    Hobbywing Max4 - EZRUN 70125 - Speedmaster P2 build

    Re the MAF I really just want a way to confirm the amount of air that its acutally flowing at what RPM and i don't have a flow bench at hand. This would help see where this unit sits compared to the actual vortech. I think it's going to come down to just fitting it and starting out easy though...

    What batteries are you using?

    Thanks for the additional info, it's great to have such a resource here. I did coincidently drive around with 80kg worth of stuff in the boot and it is denfintely noticeable, not so much in the power but the handling certainly is impacted. Keenly following your build GTHound, it's looking...

    What batteries are you using?

    Hi Guys, I'm still torn on the battery a little and trying to decide which way to go. The more i think about the charging, storage time, readiness and fire risk the more i'm leaning away from lithium based batteries for my application. Is the main reason for not using automotive batteries the...

    Hobbywing Max4 - EZRUN 70125 - Speedmaster P2 build

    Hi all - I've started making some progress on my build and all the information here has helped a lot so i thought i'd post up what i have. I'm using the P2 supercharger as it requires lower RPM which I though would be easier to manage. When delivered i found the bearings a little noisey and as...

    Hello!! I am Mateen from Silver Spring, Maryland

    Hi Mateen, cool setup. are you going to put it in your drift car? Also love the thermal images, i've always been intrigued by the hidden detail these provide. Are you testing with the outlet wide open or a with a restrictor? Looks like you have a great background in IT and wondering if you'd...

    The Sledgehammer - Shooting for 1,000hp

    Nice result!, gained a lot more area under the curve on the boosted runs. 6HP increase doesn't do it justice at all haha, it looks like 100HP at 5.5K but the feel in the seat should tell you all about that i'm guessing. Very keen to see how much of a difference it makes on the strip.

    BMS & Chargers

    Thought i'd continue this thread rather than create a new one as its about chargers. I've been thinking about how i can accomplish this in the vehicle easily. After a bunch of googling the current best idea i have is using a multi-channel 1s charger hooked up to the balance port. Charging the...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    I've actually purchased the Max4 and 70125 combo on those exact assumptions @cmoalem i think its a pretty good option for the price point. I'm in the process of making a new shaft to suit a 15mm HTD belt and pulleys. I've got a 20t pulleyfor the shaft and 24t, 28t and 32t options for the motor...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    I was watching a video by Peter Bjorck and he mentioned an off the shelf interchiller kit that uses the factory AC and just diverts it to a 2nd heat exchanger at the press of a button. seemed like an awesome solution for cooling on demand. https://fiinterchillers.com/ is the product is the...

    P2 Supercharger Thread

    @AlexLTDLX thanks for the response, These bearings are a bit noisey for my liking so i'll replace them anyway and let you know what i find. The 15kW estimate is pretty loose but its based on the turbo shaft power requirement from the borgwarner calculator. I figured if that was the "effort"...

    P2 Supercharger Thread

    Does anyone one have specs of the standard bearings that ship in these? I've purchased one and the stock bearings are a bit noisey for my liking. I'll go back to the seller to see what they think but i'll probably replace them anyway. If anyone has recommendations for new bearings that would be...

    Hello from Australia

    Hey WB, I have been thinking about how to manage that. Your solution is very tidy and having a motor with a long enough shaft to mount the impeller directly on it would be the ideal scenario. If the compressor shaft was self supporting it would take some of the tolerance requirement out of the...

    Hello from Australia

    Ah the man himself! thanks for the map. Looks similar to what i had for the turbo exept lower RPM which is probably easier to manage. Do you think a direct drive has much of a benefit? How are you feeling about the belt drive from the hobbywing video as a longer term solution? I'm not looking...

    Hello from Australia

    Hi everyone, Great to see the forum back up, I've been lurking ever since I found Alex's videos on youtube. I've got a 2011 lexus is350 that i'd love to feed some boost. There is a company in the US running 6psi from a rotrex supercharger with an ecu tune and some kind of additional fuel...
