Buschur 20g. Max boost?

[v8s_are_slow]

Just wondering if anyone knows what the max boost would be on a Buschur 20g. What's the effeciency range as well? Do they take to 30psi boost levels or higher okay? I know tune is everything but wondering what the max would be that it could handle before it decides to kill itself or it's overworkiing itself to where it's just overheating the air kinda like a T-25 would. Thanks.

Hi,

I looked quickly at the map of a MHI 20g, and 30 psi boost assuming 14.7 atm. pessure is off the map. Not sure how different the Buschur 20g is.

We made the most power at 28psi.

We made the most power at 28psi.

I'm sure you're meaning on a Buschur, correct? Just wanted to make sure cause of course not all 20g's are the same. I'm sure as heck wouldn't consider a Super 20g to be anywhere near the same. So just checking. Mind if I ask what size injectors you were using?

All 20g compressor wheels are the same. The only real difference is whether it has a TD05H (usually clipped) or TD06-6H turbine wheel. The Super20g uses a 10cm turbine housing as well. In any case, you're still limited to the compressor's flow potential, and when we switched Tort's setup from a TD05H to 06H turbine wheel, we still saw peak power at around 28psi but the car pulled hard to 8k as opposed to falling off around 7200 on the 5H. The bigger hotside wheel/housing combos will affect your powerband, but choke compressor flow will still be about the same.

So are you saying that ya tried higher boost than 28 psi and made less power so brought it back down to 28 cause it made more power? Or are ya saying that ya got up to 28psi and made the most power to that point? Just wanna be clear on what you're saying.

I injector size used? What was used for tuning as well? Thanks.
