I wanted to be there, no shit, this week. :/ But I can't miss out on their current project.

Set a goal - stick with it, then plan for upgrades if/when they come. I can't wait to see where you take it! |

You could get a new sponge, weigh it, then put it where the oil is coming out. at the end of the day you can weigh it again and calculate the amount of oil by weight..i'm sure there is a conversion you could do to ml or quarts

MPG doesnt exactly matter to me as 93 is almost always more expensive than 85 is up here. If MPGs were on my mind, I would've stopped a long time ago when I went from Stock Avg. of 396miles a tank to 287 Miles a tank after all the shenanigans. I can add em up if I get that far

Make a thread when you do it, be interesting to see the gains(if any) on a SC N52. It does wonders on the FI N54. Taskmaster what is the need for the new Fuel Sensor out of curiosity?

Been thinking of that tbh.. Only in regards to when I got to BPC though. I have their handheld with me at the house but with that sensor, if I am understanding it correctly, should allow me to flip between the two octanes... but I may be wrong. I am not too savvy and it is pure speculation on my end.

That's what I was alluding to earlier, and it seems pretty fancy. Seems like it would be expensive because the tune would have to have a huge number of tables. Even if you only read the sensor at 1% intervals, that's 100 different "tune" profiles the tune would have to switch between as it read the ethanol percentage. With that method you'd never need to "switch" between tunes yourself using the handheld or steering wheel buttons. I don't really know anything about this stuff though...

Because you then need to wire the sensor into the ecu somehow. Or somehow tell something what the E content is. It will be most impressive to see what the gains are and the bang for your buck. You got a link to that thread Taskmaster so I can stop making assumptions? I must have missed it.

Unfortunately the problem is partly the 'large' SC and the engine rpm to 7000.
With my car and auto and my driving style, I rarely if ever rev above 6000. If you set the rev limiter to 6000, you could then pulley it to have max SC rpm at the 6000rpm instead of 7000rpm. This will make more boost down low and more mid range power. |

So the stock harmonic balancer is about 5.375".
ESS SC pulley is 4.52"(115mm). Pulley ratio is 5.375/4.52= 1.19:1 pulley ratio. At 7500 engine rpm that is 8919 SC rpm. That is on a SC with max rpm 14,450. No wonder the boost curve is so lazy and low boost on top of 6psi. A 4" SC pulley will have a pulley ratio of 5.375/4= 1.34 pulley ratio. At 6500rpm that is 8710SC rpm and would make about 6psi but will have a more ramped up boost curve. A 3.75" SC pulley will have a PR of 5.375/3.75= 1.433. So at 6200rpm that is 8885 SC rpm and again about 6psi at 6200rpm. And an even more aggressive boost curve. So the problem is that over 6psi, the charge intake air temps start getting too high and cause detonation and issues. Need some type of intercooling. Water/meth injection or ethanol fuel. FMIC and water-air IC unfortunately are a packaging problem. So if the max boost non-intercooler is 6psi, and on an engine that can rev to 7200rpm, ESS has to pulley accordingly which is why there is such a 'lazy' boost curve and little to no gain at low-mid rpm, even up to about 4500rpm. My idea is if you change your driving style and engine to rev limit to 6200rpm, you can now still pulley to target about 8900 SC rpm and about 6psi. This will have a much more aggressive boost curve and more power down low and in the mid rpm range and more torque down low. If you solve the high charge IAT issue, you will then be able to run more boost, even up to 12-15psi like the BPC turbo FMIC N52 'Alice'. |
