Mazda new iconic concept car is bringing back the rotary and making it a hybrid. Should be very interesting to see in action and to hear how a current day rotary will sound like
#214 subscriber 2 things got me I live in Massachusetts was the plate on the Supra first then the ct plates had no idea where you guys were from and first was the rx7 much love.
Thanks! So the injectors will remain for now but the pump side of things is at its limit. We will be switching to dual pump with an in-tank surge hat from Radium. -8feed and -6an return. For now the injectors will be sufficient and we will up the base operating pressure to overflow them from their standard 3bar labeled flow rates
@@TailoredChassisSolutions Which pump do you run currently? I've always wondered whether dual pumps are necessary. Walbro has the 525LPH F90000285. There are also ways to boost the pump voltage and increase flow, but I don't see many people doing that. Maybe it negatively impacts pump life? Also wondered why more people don't up the base pressure to get more flow. I assume because it stresses the pump more.
@@dawggpie Currently its a bosch044 single in-tank. Mainly because the power demand/goals were lower on the initial setup (s362). You CAN up the pump supply voltage (commonly done with kenne bell boostah pumps) but im not a huge fan of over volting. Id rather have a couple pumps running well below the max duty cycle. Most pumps have an internal pressure relief at 90psi or so and there are some walbs that have a higher emergency blowoff relief but 60psi base will be more than enough and we will be sub 30psi of boost ref to the regulator so pressure demand even considering line-rate (surface friction of the line ID all the way back at the pump) we still wont hit the blowoff.
@@TailoredChassisSolutions Makes sense. Sounds well thought out. You doing anything fancy to control the pumps? I've wanted to enable PWM control for mine so that the pump isn't running full bore unnecessarily during idle and cruise. Sounds like it would be even more beneficial with a dual pump setup. Another option might be a single higher flow brushless pump, but I've heard that most of the current ones are pretty noisy.
I wont PWM control them as they can inrush spike if you arent controlling ramp on the 12v side with like a PDM. This will be house voltage supply and the idle/cruise areas will be handled mechanically with the FPR. As long as the return side flows sufficiently you dont really need to drop them down amd they hum along. The brushless stuff is certainly cool but very expensive and require an external controller that adds cost as well. For the power goals its so far off from required that its not on the radar. Id be hard pressed dollar for dollar to go brushless unless it was absolutely necessary and mechanical drive wasnt an option.
