How would a hellcat with a 2.85 and a good tune on 93 compare to a redeye say from a 45mph roll? I'm not talking from a dig because that is more driver skill.

That surprises me a little. A 2.85 cat makes what 13 to 14 pounds of boost? Doesn't the redeye make 15?

2.85 Cat should make around 15psi. Since the 2.85 Cat will require a tune as well, if the tune is done by a good tuner, the 2.85 Cat would have a slight power advantage and the Redeye weighs just slightly more. Advantage 2.85 Cat, although I wouldn't say its much.

Mine has the 2.85 and makes as high as 15.5 lbs of boost at times but mostly just 15 went as high as 15.5 with today’s runs

I'm about 800 to 1100 ft above sea level.
That would reduce my boost wouldn't it?

I like my firestone Indy 500 tires they handle very well and definitely have better traction now I’ve added more hp and I can break them loose as well as high as 65mph

I have a 2.85 pulley a tune and Demon injectors on my 2015 Hellcat. As soon as my 2019 Redeye is broke in I’ll let you know. Right now my 2015 feels stronger.
