Hey guys!

Ran a track hawk and wanted to show you guys what kind of power this beats puts out on just a JB4 with ********* and 93 octane.

Let me know what y’all think.

2021 M550 VS 2020 Jeep Grand Cherokee Trackhawk - YouTube

No way!!

[Mikeurbano1]

Yes!

Trackhawks run mid 11's. I don't think an M550 would have any problem beating one with just a JB4. Even before the Performance recall these were 12 flat cars bone stock. With the recall high-11's, and with a JB4, I'd guess probably 11.4-11.5. Throw in some E30 and low-11's seems entirely possible.

"German engineering".
GM is sending their asses to school with the LT6. LOL!

Mine runs 11.1 on map 1 using 94 fuel... With Ethanol and a good DA you are in the 10's.

[Mikeurbano1]

Haven’t ran mine on the track I usually use map 5 and that time I was on 93 octane so I think with a e85 mix it could move even better

[Boosted_8]

DA was nice last night, squeaked out a 10 second run on my map 6 (peaking at 19lbs)

[Mike_L]

NICE!!! Anything else besides the JB4, gutted air boxes and BMC filters?

[Boosted_8]

I have an X pipe in place of the resonator (don't expect any power from that) & taken the secondary cats out also.

Impressive.

[Boosted_8]

The greatest thing coming out of the US auto engineering wise right now is the 2023 Z06. That thing is a genuine masterpiece for the money! The Germans would ask $200k for that level of effort and the Brits & Italians $300k

Very nice! Thats fast.

Boosted- would you mind sharing your map 6 settings, please? I am still not to comfortable running map 2 even though it's godly fast. Also, what is stock psi? 14-15?

Thanks in advance.

There isn't actually a stock psi as it will change all over the world with the conditions. With cool air and low altitude on 93+ fuel I would expect 12-13psi at 5000rpm peak based on my own logs.

I get the best dragy times with +5psi tapered up as not to generate too much torque at lower rpm.

My fuel is 94 with a little splash of boostaine for safety.

Cool, I can put 102 octane in the tank. What does your map 6 look like? I have c#$$ed Pi!es too. Map 1 right now is more smooth but want a little more.

Try adding 5 psi on all rpm's in map 6.

[zse8h]

Seriously?

Yeah go into map 6. Set boost psi to 5 across all rpm.

[zse8h]

I can try it. Do you find it to be smooth? Map 1 is smooth but 2...ugh much desired there.

[Boosted_8]

My map 6 is actually eco mode right now with just + 2 psi haha. From memory I was running 3 psi to 3k rpm then 4 till 5k then +5 up top.
