Ok thanks. I saw PR has a DIY option for the 535, but it is still a little pricey at $445. I see a 535 can be purchased for about $145. So basically you guys are saying i can do something similar to the PR kit for maybe under $200?
Yeah I went the DIY route. I have a KPD bracket that was sold at BMP but it's not listed anymore but I have the owners email.
But any bracket that can hold a 450 will hold the 535 and it pulls the same amps as the 450 with way more flow. I have a chart I will try to link in this thread once I find it.
Here it is, the 295 is the 535 and the 275 is a 450.
Walbro GSS342
Tested flow rate at 45 psi: 246 LPH
Current Draw at max pressure: 14 Amp
Excellent value and proven reliability in a small package. While the loudest of the batch, it is still an OEM quality pump so it is all relative. These pumps have a long history and are used extensively all over the world. They are a popular option for mild upgrades.
Walbro F90000274
Tested flow rate at 45 psi: 382 LPH
Current draw at max pressure: 19 Amp
This pump has been on the market for several years and is an evolution of the Ti Automotive 39/50 DCSS ("Walbro 450" pumps). Radium Engineering uses this pump extensively in many products and customers have been very pleased with it's performance. Compatible with E85 and traditional fuels, it is a great choice for motorsports customers.
Walbro F90000285
Tested flow rate at 45 psi: 424 LPH
Current draw at max pressure: 22.3 Amp
This relatively new pump is a further evolution of the Walbro F90000XXX pumps. It is essentially a more powerful Walbro F90000274 that draws more current. Some customers do not want the extra flow at the expense of the added current, and other customers need all the flow they can get. This pump fits in any Radium product that uses the Walbro F90000274, as it is the exact same physical dimensions. More information on this pump can be found
HERE.
Walbro F90000295
Tested flow rate at 45 psi: 485 LPH
Current draw at max pressure: 19.7 Amp
The newest offering from Walbro and once again, another evolution of the Walbro F90000XXX pumps. It is essentially a Walbro F90000285, with the more powerful electric motor, but it does not feature a check valve in the outlet port like all other Walbro F90000XXX pumps. This pump fits in any Radium product that uses the F90000274, as it is the exact same physical dimensions. However, it cannot be used in multi-pump configurations when pump staging is used. Also, fuel pressure will drop to zero as soon as the pump is turned off. However, it is the perfect pump to be used in a surge tank as a lift pump since a check valve is NOT required.
AEM 50-1200
Tested flow rate at 45 psi: 321 LPH
Current draw at max pressure: 16.6 Amp
This E85 compatible pump from AEM is the same compact package as the Walbro GSS342, but is a turbine style pump. This means less noise and more flow. The relatively low current draw helps keep heat down as well. Radium offers this pump as an option in many products.
Ti Automotive BKS1000
Tested flow rate at 45 psi: 577 LPH
Current draw at max pressure: 14.4 Amp
This brushless pump setup is a perfect option for users wanting maximum flow and minimum current. Brushless technology is big leap forward for pumps. Radium Engineering has already released products specifically for this pump setup.
Bosch BR540
Tested flow rate at 45 psi: 404 LPH
Current draw at max pressure: 21 Amp
This Bosch Motorsports pump does not feature a check valve, which means it cannot be run in parallel with another fuel pump and be staged. It comes in with mid-pack performance in line with the Ti Automotive F90000XXX pumps.
Because this pump has a larger body size, it is only available in a select amount of Radium products. Contact us for more details.
