Redeye boost reading

[Paladin06]

I’ve hit my 2019 Redeye hard a couple times and it never shows more then 13psi of boost. It is stock.

What are you guys seeing?

What’s the DA/density altitude where you’re located? Here in the central Oklahoma area, which typically has a DA above sea level. I’ve seen a reading of 15 psi from about 5600 RPM all the way to the shift point, in my Redeye.

between 15 - 15.5 is the highest I hit when Hpindy data logged my car 100% stock at the track. You should be making 14.5 at least depending on where you live.

Hey so yeah I'm only hitting 13 psi here at 5300-5500 feet in elevation, was only hitting 12 psi last fall when it was still warm. Ever think about adding that incognito crank/pulley sleeve? Supposed to be good for about +2psi.

I am regularly getting 15.....I am in Florida so that may help.

A little math required, but your boost loss should be directly comparable to your HC.

I see 8.5-9psi here in my HC

8.5 / 11.5 =~74%

My modded Hellcat reads 14/14.5. It read 11 before the mods.

So 11 is only ~.5psi down, but it's also somewhat of a generalization and does rely on the air density so a notable degree.

I assume it's relatively cooler there now, so you shouldn't be suffering too much heat related air density issues.

Fuel perhaps? STK due to fuel could be causing you some timing and therefor boost?

Others should chime in on this possibility...

I buy fuel at the same location for both cars. Our daytime highs are mid 60’s to low 70’s.

I also use the same amount of Boostane in both cars for 93 octane.
