Racetronix 450 fuel pump and sending unit

[1BUICKTtype]

I'm going to have to disagree with this, The 301 is no where close to a 450 Walbro, the 450 is very close to a DW400 up to about 80 PSI but not many people go over that. The new 525 Walbro which is the factory pump for the Dodge Hellcat (oem quality and approved, made in USA) is the highest flowing single pump available.The Racetronix 725 E85 version double pumpers and all individually flow tested before they ship. These new encapsulated pumps kits are very strong most of these double pump setups flow close to 800 LPH so no single is going to come close to them. Also because I like to check my facts I called Richard Clark this morning to verify his test results and he told me that the 301 is not stronger than a 450 and the DW400 does not outflow a double pump set up so somewhere those facts got crossed up. He system of choice is the DW400 and the GN-ECU computer controlling the pump using pulse width modulation so he can keep the factory lines. This is an interesting approach that i can see being very effective but would require a fair amount of set up and ecu tuning. We have done that here with some other pumps. In the end we have some very good options for our cars from both DW and Racetronix but I would like to keep the misinformation and confusion to a minimum however.

Will Racetronix offer the 525 Walbro (dodge hellcat) pump with their hanger for the TB? Thanks

Nick, Which double pumper system were you comparing the DW 400 to. The Red Armstrong DP, Racetronix 510, Racetronix 680, or anyone who purchased the DIY DP parts and random pumps?
Were these run at 13 volts or 15 volts like when you use a volt booster
Was this through -8 feeds or stock feed lines?
Have you pulled a Walbro 450 and dropped in a DW301 and saw a decrease in duty cycle?

Mike, Racetronix makes some nice things but I have had a brand new 510 pump fail in less than 6 months. That hurts the pocket. Luckily it was noticed before it hurt the engine. Cant take that risk again. I didn't bother calling FTS to send the 510 unit in because I have seen so many times where Racetronix blames the user and don't warranty the pump. Walbro 450 units should not be sold to TR owners without the Racetronix sender setup since they draw serious amps and will kill stock sender wiring. I can count at least 3 failures in the last 2 years.

For E85,
I trust the Reds unit, with a volt booster, and -8 feed and the stock feed as a return for low 10 second cars.
I use the Racetronix 450, a volt ,and the evap line as a return for low 11s and slower.
To me that offer the most reliability, and performance for the money spent.

I look forward to seeing the new pump offerings and RESULTS of testing in FAIR comparisons.
IMHO, you both could offer a unit to someone to do some back to back dyno testing and let them post the results or do it at R. Clarks Garage at the TB.COM Nationals for all to see. If this is done on a high to mid 9 second E-85 car you can see where each unit starts to fall off.

Just my thoughts.

Racetronix has been very fair on warranty proceedings IMO. In fact we are offering 3 year warranties on Racetronix fuel pumps. The Walbro pumps are not covered under the 3 year umbrella.

With accurate pictures and description of the problem, warranties are granted instantly. Especially In your case, the pumps would have been warrantied given the 6 month time frame absolutely, so you should have called us. I would have been happy to help.

The Reds unit is simply two Walbro GSS340 255LPH pumps, certainly not E85 compliant. The new Racetronix Dual 525LPH and 725LPH pumps are fully encapsulated and 100% E85 compliant.

Mike at FTS has the right approach, keep the misinformation and confusion to a minimum.
You all have multiple options from multiple sources to choose from. Each one promoting their own while trying to play off others. Pick the brand and source you are comfortable with and let them guide you through the setup and work with them.
Every company wants your business, if you have issue - call them. You will find in most cases that the products are well designed and manufactured, you will end up with the performance you are looking for.
