BSFC (score: 1): Author: "gary baker" <lsr350@hotmail.com>; Date: Tue, 16 Sep 2003 22:23:47 +1000; Im sizing some injectors and the rough estimate is a BSFC of 0.65 pounds /hour per HP for a turbocharged motor, what I need to know does this hold true for methanol do I double this figure or work o; /html/land-speed/2003-09/msg00435.html (7,713 bytes)
2. Re: BSFC (score: 1): Author: "Lorcan Parnell" <lorcan@750turbo.com>; Date: Wed, 17 Sep 2003 08:21:47 +0100; 1hp of methanol is 1lb/hr. For a 4 cylinder motor with 2 injectors per cyl (I'm assuming) and 600hp you would need 8 x 94lb injectors to allow for duty cycle. I would be tempted to go bigger still o; /html/land-speed/2003-09/msg00456.html (7,884 bytes)

I would be tempted to go bigger still or allow for an increase in fuel pressure (buy 94lb injectors at 40psi then you can run up to 70psi if you need to) because of the; /html/land-speed/2003-09/msg00472.html (8,142 bytes)

Re: BSFC (score: 1): Author: "Lorcan Parnell" <lorcan@750turbo.com>; Date: Fri, 19 Sep 2003 00:44:03 +0100; It's a good question, and you are correct - increasing the pressure does increase the response time slightly, but within the range I gave it does not present a problem on most injectors and will prod; /html/land-speed/2003-09/msg00473.html (9,314 bytes)
5. BSFC (score: 1): Author: "3liter" <saltfever@comcast.net>; Date: Fri, 19 Sep 2003 00:10:55 -0700; Lorc, thanks for the EFI information. When Rick Yacoucci had his engine on the dyno he indicated he was trying for 11,500 rpm! That would be an open time of less than 0.2 msec.

At 10,000rpm you have 12 milliseconds available to open the injector, inject fuel, close the injector (injecting every other revolution of the engine; /html/land-speed/2003-09/msg00476.html (7,346 bytes)

Re: BSFC (score: 1): Author: Dave Dahlgren <ddahlgren@snet.net>; Date: Fri, 19 Sep 2003 04:21:48 -0400; I am sorry to say it must be your controller as i have had injectors both flowed at these duty cycles and raced with them there as well and never experienced this in the last 12 years.

12. Re: BSFC (score: 1): Author: Dave Dahlgren <ddahlgren@snet.net>; Date: Sat, 20 Sep 2003 05:10:12 -0400; fuel pressure is specified as the rail pressure with key on engine off.
