Faster g27

[ElectricDevil]

So i was searching around late night and ran into this video on youtube of a guy who swapped the stock motors with 12v motors on a g27 and now it's super fast
what does everybody think? i seems like a simple mod

There was a company that made a mod a few years back like that and it wasn't simple at all. Shaun Cole from the Simpit (ISR at the time) still runs that wheel I think. Maybe reach out to him?

The way that thing is smacking back and forth, it seems like you'll have to change more than just the motors.

Look at the comments below the YouTube video: he has installed 12V motors which are still supplied by the stock 24V power supply. He says the motors will overheat quickly, so you need fans to cool them down. But I don't know how long they will last: 12V motors running on 24V(!).... But yes, it seems like a relatively simple mod. Links to 12V motors are also in the comments.

i see them im wondering how did he find room fit the optical sensors on the axle of the replacement motors he says he got them off a cordless drill

i believe ArcTeam, thanks i'll send him an email to see what he says

I don't believe he ever actually got his up and running and when he left ISR and started simpit he was trying to sell it. Not sure if he ever did sell it though.

Jeez! The FFB would be nuts strong on that. Those poor plastic gears! That said, why 12v? I would have to believe something live 16 or 18v motors would work better. I mean, that video looked brutal, like it would rip the wheel from your hands. 16 to 18v would be a bit tamer and would run cooler.

He was using it in a fairly recent video, and I know he had it working. You can see the wheel in THIS vid.

Be interested in hearing how he feels about it compared to the newer wheels hes tried. It seems the ARC mod went the other derection by using a 48v motor instead of 12v. Here is some old but good info on the mod. http://www.racedepartment.com/threads/arc_team-g25-e-mod-review.42554/ Or whatever they have done to make it more powerful.

If you just swap the motors and do nothing to increase the power supplied to them the best you can hope for is 48W and probably significantly reduced MOSFET life, if I remember correctly the stock G27 motors never draw close to the full 1.75A and the FETs can't handle a sustained 48W load anyway. I suspect what this mod has achieved is a higher average power draw (but still under 48W) and basically shifted the balance from medium speed, medium torque to high speed, low torque - it may seem impressive but I'm sure the FFB is weaker, maybe the same as the stock motors but I highly doubt it's stronger. I mean, 48W is 48W, if you increase the rpm the torque has to drop otherwise you're getting more power for free which is impossible. It's impossible to know what exactly the deal is here without the datasheet or some test measurements but I'm pretty sure it's just faster and probably weaker.

On the other hand, if you swap out the motor drivers (the MOSFET H-bridge) for something more substantial, which is easy in theory, you could hook the G27 up to any DC motor, even a starter motor if you wanted. The ARC Team G25e (I think that's what they called it) did something like this but I haven't been able to get any info on it, I even messaged someone on YouTube who had a video of one and he refused to tell me what was in the kit even though you can't buy it any more anyway...

He won't see the tag because I'm editing my post but @eKretz would be able to explain this better.
