    2014 Spark
  1. Thank you for the feedback. Like I said, I'm learning as I go. I got this car cheap and I'm passionate about ethanol. I'm hoping the high octane may allow for compression that would not be possible otherwise. Here is an interesting article on E85 and effective compression ratios if you are curious why I think I can get away with this
  2. Search octane and high compression ethanol has higher octane you can run on higher compression and more efficiently. Read the source and research more. The above text highlighted is dirctly on point to your question. Look up E85 turbos and high compression. By using a high octane fuel, engine designers are able to implement various techniques to improve reliability, efficiency, and power output. First, it helps prevent knock. Engine knock, or pinging, occurs when a separate pocket of air-fuel mixture ignites after the spark has ignited the air-fuel mixture within the combustion chamber. This is obviously undesirable as it can cause serious engine damage, and it can be prevented by using the proper octane rated fuel. Second, higher octane allows for the use of higher compression ratios. Compression ratio is directly linked with thermal efficiency, so the higher the compression ratio, the more efficient the engine will be (law of diminishing returns certainly applies). These are my thoughts: E30 has "less energy" but the 101 octane allows for higher compression without knock and more fuel efficiency, if tuned properly. The spark is at 10.5:1 (or close) and a turbo with low psi could increase that a bit and you can take advantage of the 101 octane in E30, which is actually cheaper than 87, by quite a bit.
  3. Ok, from what Ive read I can add small boost and the compression can still be increased. I've also seen quite a few people insulating intakes but I'm the type of guy who isn't scared to try these things and report my findings. Call me crazy. Have you tested these things or do you just know it doesnt work because, well, that's crazy? I'll let you know how the turbo goes.
  4. I'll let you know when I'm done how it goes, thanks for your support.
  5. Perhaps a canoe harness?
  6. Remove the resonator. It is below the air filter. I acessed mine through the driver side wheel well. From what I understand it increases airflow; It seems to be good for performance. It's free and reversible. Better instructions on this site. I am happy with the results.
  7. Insulate the intake. In my car it goes right by the exhaust. I bought some tape for air ducts at Lowes. I think it helps but you can do your own research or spend 7 bucks and test it out.
  8. I used "Noice" and I bought 25sq feet on Amazon for like $35
  9. Rear seat removal and sound reduction. I made sure to get the wheel well area as well. I have not tested the sound reduction yet.
  10. I'm learning as I go but if you increase compression you can benefit from the octane in the ethanol. I'm going to try and add a turbo from a sonic to increase the compression. There is an interesting test with a Cadillac and Ford fiesta. They tinkered with turbos and saw great results with mid level blends. I'll post the link here.
  11. Half shaft your throttle body. I run my 2014 1.2 on E30 and I saw great mpg increase. It also seems to have made it zippier all around. I have donet this and the resonator mod so far. To clarify, the mods are responsible for the benefits. I run E30 because it's American made fuel. Also, I'm getting great mileage after these mods and paying way less at the pump The picture is of my variation of half shafting the throttle body. I removed the TB, shaved the excess bolts off, and cut the middle of the braces on both sides out. Make sure you have a good connection when reconnecting the TB. I broke the red clip and had a bad connection, it triggered my reduced power, limp home mode. Fixed the connection and it runs great.
