Turbo 93 & Meth tuning

5.0 Turbo 93 & Meth tuning

Anyone having success tuning 93 octane pump gas & 50/50 methonal injection on coyote with turbo or centrifugal?
I'm planning to go Turbo i will be using the stock intake im curious how well the meth injection would equally distribute to all 8 cyl id like to run more than 9-10 psi on the street but im skeptical on trusting meth on my application. I had good results on my 3 valve using a JPC cast intake they Kurgan able to tap bottom of intake and place 1 nozzle between the first 4 intake runners and 1 nozzle between the last 4 intake runners and it performed really well. Used a AEM meth kit with dual nozzle.
Unfortunate we have no convenient E85 stations in my area.
Yes the motor will be built not stock.

Guess it isn't as popular on a Coyote yet.
Kurgan did a good job on tuning my paxton novi 2200 3 valve with meth injection they used the stock windshield wiper fluid reservoir with Aem kit they pretty much had the tunning nailed on that combo.
E85 isn't big in my area plus i tried it when i lived in Colorado corn fuel was fairly popular there but my gas millage dropped by 20 + % per gallon / tank and i hear that e85 isn't great to use if you let your vehicle sit mine sits for 2 plus weeks between drives.
Wish someone would take the time with the Coyote and get the 93 + meth tunning nailed on a turbo application i don't know that it would be all that much different from tunning a centrifugal for meth injection.

you will have to wire up a Iat sensor.. I believe you can do it with some of the wires off the MAF I believe!

How much are you trying to make?

 

[JPO8GT]

I would like to be able to adjust boost from around 600ish to 700 - 800 tops rwhp on street and still retain stock 11:1 compression on the short block im not sure but im concerned that Shell V power 93 alone won't do it safely but i don't want to give up anything when running race gas at the track so im trying to keep the compression in the 11's. Im not much on the knowledge side of the coyote and it's tune ability so this may be doable but i just hope so safely.

6-650 is pretty easy thru the A6. Hard part with turbos over a centri is the power comes in much faster. That will cause your octane problem. You can use the boost controller to give you more up top to avoid that area like a centri does. But looks like meth is your only option. I'd personally feel better direct port. I just never could get over flowing fuel thru an intake not designed to flow liquids or the other possible problems. Lots of guys do it though.
Although I don't see any reason a coyote would be any different than any other engine.

 

[JPO8GT]

I'd prefer a direct port setup myself that way i know that one or two cylinders arnt taking the beating probably would be the back two cylinders that get screwed. To much $ invested to take that chance.
Wish some one would develop a direct port meth injection similar to a direct port nitrous setup would be great! At least you would know each cylinder was being feed equally and be able to better fine tune.... E 85 didn't sweep the county like the auto makers thought it would and if you ask me unless it we're to be 50% cheaper than gas it's never going to happen.
It's availability is spotty at best in my area. Hell i can find ethanol free premium every where here.. Thats because the ethanol is screwing with the farm equipment and boats that use carbureted engines.

I bet if you sent your intake to a nitrous company they would set it up for you. Or hell probably any local race shop. You'll have to jet the methanol down like nitrous for individual runners. It'll just end up looking like a mechanical fuel injection setup. Pretty easy though. No bending lines, just a flexable push loc setup. Easy peasy.

 

[JPO8GT]

Now your talking! I thought i seen a direct port nitrous outlet setup that looked pretty slick now i got some homework to do! Lol.. Yep if it had a progressive controller that increased the meth flow as boost increased.. I've seen up to 3 nozzles on a aem kit used calculate max flow of 3 divide into 8 nozzles and may get close on nozzle sizes needed hummm.

 

[CPRsm]

I bring out the worst in peoples spending habits lol

 

[JPO8GT]

Haha. I already sent Nitrous Express a message on a direct port methanol injection setup for Coyote. I'm going to be broke if i build this car like i really want it!

 

[CPRsm]

Yeah that happens lol. Also check w AIS and methanol injection companies. They may have already done something like that and know the jetting needed to equal what you'll need.

 

[stang8psi]

AIS is the only company I deal with.. And don't forget to get stainless lines as the nylon ones tend to break and leak easily!

 

[JPO8GT]

Cool i forgot about AIS i looked at their stuff on last car build..
I will just have to roll 600's on the street if i can't do a reliable direct 8 port meth injection system. Not going to trust just fogging it pre throttle body..

 

[CPRsm]

You can roll 650rwhp if the kit is up to snuff. Back pressure, inlets temps, etc

 

[JPO8GT]

It's not like rolling 650 on the street is week..still plenty of power to walk car at most speeds especially on street tires. I sent message to AIS & devilsown if it not crazy expensive it would be worth it just for some room to adjust and play with a little more without having to switch to race fuel every time. Then you could switch to race gas when you want to really wick it up at track.

 

[CPRsm]

650 isn't weak sauce. But when you get used to playing w boost much higher, you become pretty jaded and then low boost becomes "eh." You'll see. I started loading ice in my tank so I could crank 91 up to 850rwhp. We all start at 500rwhp at one point or another. Then the itch becomes harder and harder to scratch.

 

[JPO8GT]

Your dead on!! I know that feeling i started at 410 rwhp 3 valve wicked it up blew it built it changed blower wicked up to 670 rwhp burnt a ring built a 326 Stroker boss block changed blower again wicked up to 750 - 800 rwhp with 93+meth inj at track ran c16 900 rwhp best 1/4 was 9.63 _ had a chick in Escalade pull out in front of me BANG TOTALED CAR.. Now i feel like this stock 5.0 is a 4 banger..
Starting over.... It's funny how when you get used to the power it doesn't feel as fast as it is then u add more and anyone else who rides in the car gets the shit scared out of them.. .. No more blowers for me done with throwing and changing belts & pulley's > Turbo..
I love this hobby or i wouldn't stay with it went right out and bought another new stang!

running 633 RWHP on 91 octane here on my kenne bell. I have the meth kit just for safety in case of bad gas and to cool my intake charge. the meth kit injection port is sandwiched in a 1" spacer between the blower and the intercooler.

Yeah see, you know. Went full blown right out of the gate w an engine. Just skip right over the 700 rwhp level the stock engine lol
