A2A Supercharged Intake Options

Senna-F1 · 01-28-2020, 07:33 AM

I was just reporting the readings, and making a point that I wasn’t even selecting the highest one, since there was a lot of disbelief over my numbers. Having said that, Eugene says boost recorded by dynos are typically lower because they use a longer vacuum tube to reach their sensor. Vacuum loss over longer runs. I still hit high 14’s on the dyno I believe. I don’t understand why an unknown dyno with unknown sensors and vacuum tube length is somehow more believable or comparable than the equipment virtually everyone here owns. Probably a 4 bar OMNI-Power sensor, a couple feet of tube, and ECUTEK software. These are all constants, so why not rely on them instead of insisting on boost numbers from a dyno?

I know reading boost numbers is nice. But where it all matters is how much its laying down on the dyno. Do you have those results?

½ of them. Right now I just have the E53 dyno. When I asked why just 53% Ethanol, they said to keep it safe for a long life. I don’t know... but I’m very happy with what I got.

With my intake and filter, 9 psi pulley, and On E53, I made 618 WHP and 452 WTQ @ 14.7 psi. I’m guessing that’s a boost record for a filtered 9 psi pulley setup. I don’t even see turbo guards making that kind of boost.

I hope to be in that area of power and pressure once I'm done with tuning. Likely mid-March after gallery gaskets get done, will I be able to hit the dyno.

Looks great!

Yes, that's awesome! Any thought as to what the pump gas numbers would be? Is it 93 octane in your area?

Thank you sir!

It is 93, and it should be in the 550+ WHP. Not sure on TQ. I’ll post it once I receive the plot.

I would take my own pressure meter and ECU readings over a dyno vacuum tube any day!
