🔧 Technical Thoughts on running E20 instead of straight 93 for knock protection?

[sktchy]

I think to even look at upgrading injectors your into lingenfelter shit and a set is like 5k? I'm sure a 30% over cam lobe would help out quite a bit here and at least get you on e85 but this is way beyond me playin around with trucks too

Don’t recall the keyboard shortcut for android. ??‍

It's the same ⁰

Woah ?

Wait don't these things have di and port fuel injection nowadays?

Ls swap it

 

[sktchy]

I suppose one could find a way to stick an extra set of port injectors in the intake for all the fuel? Would probably be just as much work and money as throwing a cam in though

 

[Shawn1112]

Lol half way there... Im $10k into this with the maggie 2650.

So why not spend the $5k and go straight corn? It sounds to me like your looking for a cheap fix, which is probably going to lead to a huge repair bill.

Saving money at the moment for the next step. Going to be cam, headers, bigger TB and inlet for the blower than adding meth most likely. I don’t want to but it’s that or the port injection setup that’s twice the cost.

IDK man, sounds like your playing with fire. I'm not as smart as most of you with the going fast shit. But one thing I was always taught was never cheap out on the fuel system. Hence the reason I'm kinda going overboard with the fuel system on my 71.

Because the high side is mechanical and ran using the cam fuel lobe, in order to get more headroom from the high side pump you have to change the cam. So that is helping the fuel system. I already have the low side covered with the JMS. The injectors have a ton of headroom left. Im topping out around 5.0-5.1ms and the top is 6ms. So we are good there.
This is the part of DI motors that everyone has to deal with. And its normal to run the voltage booster for the low, and a cam with bigger fuel lobe for the high side. That will buy me the head room to get to the mid 800's without E or meth.

 

[sktchy]

Sounds to me like you've tapped out 93 anyway so you'd need a cam to help keep kr down as well as add fuel.

My vote goes to asking your tuner to pull about 3⁰ out of it and driving it until your ready to make the leap. You may be surprised and it might even pick up hp.

 

[sktchy]

For reference if I hit 24.5⁰ on an na lt di motor I'm done. I'm sure they can take more but I'm not that guy that likes to push expensive shit. Your running that with a Maggie.

My ls wants to run 27⁰ stock tune on e85 and does with 0 kr but it's happier around 24 or 25.

Don't take this as a negative comment, but man do you have bad luck with projects.

This.

For now, I would just use good unleaded race gas at the track (VP C10, MS109, or Sunoco 104), and avoid hooning on the street.

Save up some funds to upgrade your fuel system the right way. $5k is a small price to pay to avoid a much higher repair bill later on.

chickened on the E. Ran straight 93. DA 180 tonight and that’s all she’s got. Nothing changed from last outing.

You won’t get any benefits after e60, and it washes down you cylinder walls, reducing lubrication. Higher the e mix, faster you accelerate engine wear. Use the best oil with a high zinc content, and change it frequently

For some, the best option may be a Tesla Model S Performance or Plaid and enjoy it.

Yes that's what I want to drive a f****** toaster oven with wheels.

Give me fuel give me fire give me that which I desire

Your Hellcat 60ft similar to my GTP.

 

[cdh027]

My stock (ported throttle body, CAI, Borla secondary cat delete) LT4 pulls timing on 93. It pulled timing straight from the factory. I ran 100 pump for years and it loved it, but the nearest Sunoco with 100 is about 45 minutes away now. I think I may start taking the drive. It's really a different car with it.

 

[cdh027]

ZXMustang where are you at? There is 100 pump in south sarasota, clearwater and auburndale.

Im north of Tampa. Would take 45 to an hour to get to Clearwater. At some point im going to order a few pails of MS109 and just add a gallon or two, to each tankful of 93.

Did your GTP also close the throttle to 49% and also short shift by 1000rpm in 1st? If so that would be impressive. But in reality I could be in the 1.4x short time if the car would stop closing the throttle blade and short shifting. Thats something a trans tune will cure though. Then that MPH should be more like 140.

What did it take for your GTP to cut 1.4x sixties and trap 140s??

 

[ZXMustang]

You can see in the log where the pedal is full on but the commanded throttle opening goes from wot, down into the 40s then back to wot in first gear. The car then short shifts every gear after that by 500rpm, well under the peak of where the car made power on the dyno. This thing has a ton more in it.

Some torque management might be helping out your 60ft and I am not sure short shifting matters in the first second and a half of a run. You must have rage quit a while back when I said Greasy blowers wine reminded me of my GTP after driving it. Thread participants LOL'ed at a GTP versus Hellcat comparison so I took a crack at another one.
