I've had a dual fuel system on my car since 2006. It uses 93 & 116 octane, and it automatically switches over from 93 octane to 116 octane at 12 psi of boost. When I built mine back then, there was no information on the Internet about how it could be done. Mine uses a simple NC/NO relay and blocking diodes on each wire of the injector harness. Very crude but it absolutely works! I still have it working on my car to this day. It's absolutely the BEST MODIFICATION I ever done for street cruising while still being "on kill mode" when I wanted to have some fun. And you're right, it transitions over from one fuel to the other very smoothy. You literally can't tell when it switches over. I have a couple of videos of it that I uploaded to my channel and on my web site.
As always Steve , you go way above what any other engine builder pass's on . Every day your my personal teacher , this one was special to me , as I'm setting up my Aussie Ford Barra Turbo as a drive and drag setup for our Aussie drag week , and needed to use the same dual fuel setup but didn't know how , now I'm hoping I can get my Haltech ECU tuned like you did with the FT600 . I have the Areomotive Red Belt driven Mechanical fuel pump with Siemens 2400 X 6 as my street injectors and the FT 520 x 6 for methanol on a Aussie Plazmaman 12 injector manifold , running a Nick Williams103mm DBW throttle body . Love every detail you give us . 💯 percent Outstanding quality and knowledge . Thank you again Steve . Dewey was a bit camera shy today , lol love his content .
Love the dual fuel system and seamless transition from one to the other via the programming. I recall when Kevin Smith programmed this into one of Cleetus’ cars. Not sure which one. Mullet maybe? BTW, great LS build. That sucker is really efficient to make 1000 on only 6 lbs of boost!
@@1982evilj It's really simple to understand how much HP an engine makes N/A. Atmospheric pressure that we all have at sea level is 14.7 PSI. That's what you and I breathe every day. So if a turbo or blower is adding an additional 14.7 PSI then the engine will double the HP level over and above what Naturally Aspirated would provide. This is assuming that there isn't a poorly sized turbo or heat takes away from efficiency. So in this case 6 PSI is adding roughly 40% additional HP over N/A, which puts the N/A HP level at roughly 650 HP.
I am amazed that all that stuff will fit down into a Nova, those headers are all over the place. I have a 66 Nova with a straight axel with fender well headers and I thought that was a hassle to to get those bolted on 😂 ..cool video keep them coming!!!
Steve you explained the fuel tables perfectly. You made to where even a dumb hillbilly like me could understand! Keep the great content coming I love to learn.
I’m 41 and a union sheet metal worker with numerous weld certs. Been in the trade for 20 years. Ended up having heart failure a few years ago along with 4 strokes. They won’t let me work so been fighting disability for 3 years. We love what you do. And if I every get my disability my first thing will be buying some merch lol. Love your boost shirts. Hopefully will be trying to build an ls turbo truck if possible. Keep it up
Hang in there buddy. Keep up the good fight. The one good thing about fighting those fuckers is the really big check when you win. Mine was for like 90k… damn near starved before I got it. Thank god I had short term disability insurance for the first part of it. Took me almost four years because they had a huge backlog of cases. It was fucked up. Just going thru the motion till you get to the Administrative Law Judge. 30 min later. Case over. Slam dunk. They just keep saying no till they have to say yes. Fuckers. Am I bitter? Yeah, just a little.
Thanks bud. May 2 I have court for it. Been turned down 3 times. Last time I had court was 17 months ago and was awarded a year. Ya they owe me 2-1/2 years back pay. I appreciate the reply. What did u get it for.
How good would it be if those mechanical fuel pumps had a clutch system like a/c compressor, then you would not have to remove all the time Keep doing awesome and teching us stuff =)
The load is a couple times what an ac clutch handles. That being said there is a blower on a Volvo boat engine that runs a magnetic clutch. It's a beefy unit.
Toyota did use that type of clutch for some of there small superchargers. Convenience factor goes up but reliability goes down. You add in a extra failure point. Slipping the belt on and off really isn't a inconvenience. Much less then swapping the set of wheels over for a drag and drive car or lashing the valves.
You can use a electromagnetic coupling on the high pressure fuel pump that can save you alot if you can have the control of its engagement and disengagement from within the cockpit. Similar to the coupling found on ac compressors and superchargers.
Bad ass! Very cool to learn how to do things in new ways. And you are obviously extremely willing to learn new things and new ways to do them. Thanks for sharing!
I think that Kevin from KSR does always the same thing on cars. Normally they run on normal gasoline but when it sees boost it changes to methanol. Its a nice system and easy to use for the drivers
having the direct dual fuel seems like the better option. Idling in the lanes, moving around the pits, shutdown/drive back all on street system, and saving the methanol for the important stuff.
I appreciate all of these videos it’s truly amazing how technology totally changed the racing world. Thinking back to the days when we generated horsepower with a GM 10-71 blower topped with a set of Holley 600 cfm carbs on 400 ci four bolt main sbc. Now a day you can complete system being turbocharged or blown system and add bigger injectors and a higher volume fuel pump then have someone reflash the ecm and make 1000 hp.
Kevin from KSR was the first one I heard off doing this dual fuel setup. Not on Fueltech, btw. Super Nice videos coming almost every day. I hope you get that YT money, because the content is Top Notch!
Steve I've been watching for a while, learning ALOT from you. I wish I had somewhere near me that I could work at that is as knowledgeable and perfectly set up as your shop. You're doing an amazing job!
Steve, you are that man! I’m doing my street car as a duel fuel 93 to E85…At 5 lbs I’m having it switch over, but using a Fitech, it has had its own challenges..
Hi Steve, use a fuel pressure sensor in the methanol rail to activate race mode and co2 control. When the belt is attached, the ecu knows its capable of more than wastegate pressure.
That's a pretty good idea. Could be a dumb system with a hobbs switch and a CO2 solenoid. If the hobbs switch has pressure, CO2 is on. If it loses pressure the CO2 is off.
@@jagharingenyoutube Simplicity still has a place in modern engine programs. Call it belt and suspenders. Additionally, not all ECUs have the extra I/O or the programmability to do it. CAN bus PDU/PDMs certainly make all this easier these days though.
Thanks for breaking down how you tuned for dual fuel systems simultaneously. I do something similar but with pump and E85. I don't have a mech pump so I'm just turning the aux pump on/off @9psi. I think dual fuel systems have become a tuning solution for many enthusiasts trying to dig every last hp out of their combination.
This dual fuel is really cool... if someone wanted to go cletus mode would you be able to do methanol on both sets of injectors and really get the horses ramping up. If so maybe have a 3rd tank(auxiliary methanol) with electronic valve that draws from the main E85 than switches to the auxiliary tank for a much higher lb per hour duty cycle utilizing both sets of injectors.....without going Boom😅 really cool set up!
Mr. Steve Morris, I'm so glad that you decided to do a RU-vid channel and spread some of your knowledge. What made you decide to do a RU-vid channel in the first place if you don't mind me asking? It would be an interesting video if you were to talk about how you decided to create a RU-vid channel. Again I appreciate what you are doing here. Thank you
Anybody else remember when 2000hp was only from blown mountain motors on race fuel only and only in things that were built to fit it? Now 2000hp engines can drive anywhere from pump to pump and they fit like they came out of a stock pickup truck.😂 Because of the few like Steve Morris and GM😂 we’re living the great days of hp.
Time for 4 cyl smx. I'll say it again so many k swaps out there there needs to be a SMK in the world big block 4cyl with hoops in the heads and receiver groove in the block. 1/2 smx. SMK. Just saying there are 100000 k swaps with broken blocks at 12 to 1400hp lifted heads. The world needs a 2000 to 2200 hp SMK. Kyle at boosted boys can do your test and tune.
@Dan Myers not Hondas. They k swap everything. Sand rails, all types of cars, air boats, jet boats. When you need a small compact engine that's light weight but big hp. 4 cyl making 2000 plus hp would have so many applications. Especially a drag and drive settup. K series honda engines max out at 1400hp and no way they can do a drag and drive at that. Look at pfi speed they split a block in half. It's a big market k series engine swaps. Like his SML lots of swap potential. It's business potential. Plus half the machining for him to make one.
Yea for big 💰 you can get anything built or done, it's all bout what you would wanna do with yr million dollar machines. But if you had the machine to build it from scratch, I'd say go big, change up the design and do over head valve with bottom exhaust ports and make it a 2 stroke instead of 4 stroke.. in reality that shud double yr hp to yr lil 4 banger, 4 stroke is more for efficiency and gas mileage 🍻
Back in the 90s I had an accel dfi. That was when I noticed most of my street driving was at 10% throttle or less. It gave me a similar idea. the technology now makes it so much easier to implement.
You should make sure Bret or his builder puts in some sort of light/regulator combo so he knows when the CO2 is on, that way if they happen to forget to take off the belt and leave the CO2 on when they go on the street and they run out of methanol + it starts going lean/dieing when the boost comes on it will give them a clue as to why. Easy safety/anti-bozo light. Now that you've set the fuel maps up like this on this setup will you be changing to it for the Wagon or (offer to) do it for other customers with other ECU's too?
I think it amazing to change tunes that fast!!! Just flip switch for tune and fuel might be better to save pump life. Also less belt removal. Ac clutch won't handle the torque/rpm? Something similar?
Anyway to make it stay running on methanol after you hit the target boost, for when the driver has to get out of it, and back into it. I know the dual fuel systems have a stutter trying to get going again.
Makes sense it should make smidgen more power, less lag, smoother boost by ridding intercooler. Curious what the differences between spraying methanol pre compressor would be versus swapping over. Either way its less plumbing to pop apart on race day with a few less pounds. A nice build.
Damn I wish I never quit building engines!!! But unfortunately up here in VT pre internet there wasn’t a ton of business up here except selling guys motors they would put in their street cars then wreck them.
Steve great video. Isn't that how Cleetus was running his old 540 BBC. It would do his burn out on gas and drive in pits on gas. He would do his run on methanol. I could be wrong. Thought it was a great idea..
Steve: Always Thinking! Always Amazing too boot! Even though most of the time it's over my head?... I feel Ur trying to make me feel like I'm get'n It! Thank You, J
You should install draft lines from a freezer to your turbos. Be interesting to see if the super cold air improves hp and by how much at this level. I’m aware this would be a costly expense.
NIce dual fuel system. You could make some safety maps to ecu with fuel pressure sensors. If the methanol pressure is low then dont allow the CO2 to come on or switch it off, so then only thing for the street drive you just take the fuel pump belt off, also if you dont remember fill your methanol tank it runs only with gate when the methanol pressure drops and possibly save the engine with dumping boost.
Another great video Professor! It'd be nice if you started messing around with stratified charging... injecting just enough methanol on the intake side of turbo to cool and premix an incombustable (detonation prevention) volume of air whereby the injectors can 'make up the difference for a stoichiometric burn.
I have a feeling that this dual running setup won't be a good strip idea now imagine...2 step 3k rpm 4psi then you start to go 8k 30psi then you shift to 2nd drops rpm and psi again then back up so the whole time it's trying to switch back and forth from 1 fuel to the other in the matter of 3-4 gear shifts and 7 secs, would it be possible maybe but there will have to be more tapering in and out then cut and dry 6psi limit, id recommend leaving the 2 fuels as seperate tunes until you got a solid dual fuel strip log and not just from the dyno
It would be a really cool setup if you could put the mechanical fuel pump on a magnetic clutch type of system rather than removing the belt. Then, you could use the system logic to turn the fuel systems on and off as needed
People have added a second fuel rail before, but I've never heard of plumbing it to a different tank with a different fuel. Who thought of this and what were they doing at the time.
