Whipple at high altitude? 7000da +

[v8ter]

So who's running at high altitude with a Whipple setup? Wondering since Im around 9psi with a 3.50pulley, and whipple says I cant run o/r longtubes with their cal, and I already have them lying in my garage and dont want to buy hi-flow cats , so Im looking into options on what to upgrade and what pulley/gas combo to use when I get the headers installed

I managed a 11.50 @ 128et 1.71 60' , Hoosier 28x10-17 slicks , shifting close to 7800 , and using 92octanes and octane booster.

Next is suspension mods, and find a combo that would get me into mid 10s with a da greater than 7000

Your question was, "So who's running at high altitude with a Whipple setup? "...assumptions aside, what specifically is your question? If one where to answer your question, the response, "I", "Me"..etc would suffice. You want to know fuel and pulley combinations that will net you your current PSI without HF Cats? Maybe you want to know if you can run o/r longtubes without HF Cats? Inform the un-informed.

Who said you can't run whipple Cal without cats? Plenty of people are. Including myself. I'm at 3000ft and have been up to 9000

I confirmed with Whipple that you can run their tune and no cats, you use foulers. I've been running that setup for 4K miles no issues.
