2018 Jeep Trackhawk
Discussion
Some good fun at roll racing with a bone stock SRT (480BHP) against my 825whp Trackhawk.

Honestly, this is getting mental!
60-130mph in 5.93 seconds! In a 2,400kg brick! 100-200km/h in 5.11 seconds.
Hitting the 1/4 mile on Saturday and looking for a 9.8/9.9 pass.

Yep, best mod I've done. Keeping these superchargers cool is the key to keeping it happy.
Thanks. Thinking of putting one on my Monaro. Did you keep the front mounted heat exchanger or rely on the chiller only. Also, how big is the coolant reservoir you used? Heard mixed reviews but I think it depends on setup so would be interested to hear what’s worked for you.Insane car by the way!

I deleted the heat exchanger and no downsides to that.
I have a 6L reservoir which is pretty close to perfect for the 1/4 mile passes. I think the Holden's here run a 12L version.
I've heard nothing but positives and it's proving to be a big hit with the Hellcats and Trackhawks. Their spacer plates are also very good and my IATs dropped 6-9c by that alone.

Great, thanks. Good to know. Looks like I’ll order one. Massively impressed by the engineering that goes into the Trackhawk but they cost a lot so to be expected.I deleted the heat exchanger and no downsides to that.

I’m wondering what can be achieved with an SRT8 and a 6psi procharger. Not the same beast obviously but still good for 500+ whp.

Holy thread resurrection batman - but better I guess than starting a new thread of '2019 Jeep Trackhawk'.
Well, I gave up waiting for the TVR on deposit, and wanted a big front-engined V8...but not too flash or ostentatious; one I could drive every day and not have fingers pointing or worry about parking. One by one the alternatives got eliminated - plus I've had sterling service from my 110,000 mile + Grand Cherokee 5.7 Hemi - so I bought a TrackHawk last week
Sounds absolutely glorious, and for anyone slating off interior design, comfort or quality then unless the leather was from whale foreskins hand-stitched on a virgin's knee, and the hard/polished surfaces were unicorn horn burnished by elf craftsmen I can't see anything to criticise it. ...and that's coming from a Maserati which is often held up as the pinnacle of interior style and design. Lots of toys tooi, including some useful ones like the adaptive cruise that will also emergency stop, and the cooled seats are fabulous.
Drove it up from 'down south' and very quiet and relaxed on the motorways. Fun on a wee cross country dash (sits amazingly flat in the corners), been in to town a few times, got stuck in traffic, been up to Tesco and back for beer. So it does all the things a daily driver is meant to do...and relatively low profile.
But having hit 500 miles it's now possible put the foot down, and launch control has just been enabled First (and so far, only) go at a timed 0-60 says 3,3 seconds. Not too shabby. Once I get lots more miles on it I'll get it out on a few track days for a bit of fun 
I'm sure virtually everyone else will be saying 'if I was spending that much on a car I'd have bought an [insert model here]'. But I thought long and hard about it; and no regrets (and I got a stonking deal). It's a daily driver thats happy on speed bumps, putholes, puddles, (moderate) floods, snow, motorways, A-roads and B-roads - sounds like armageddon with the foot down and wafts along otherwise. And did I mention 710 hp? That's SEVEN HUNDRED AND TEN HORSEPOWER (as stated on the 2019s)..
Congrats, you're going to love it! They can handle their power very well, you'll be wanting an extra 100HP soon!

I had a chance to race a stock Trackhawk on Saturday at roll racing and it was good fun.

After nearly 2 months, I finally get a chance to lay down a 9 second pass this coming Sunday. Can't wait!

Close, but no cigar!
Best of 10.13 at 137.75 MPH. It was extremely consistent with 8 passes and all of them between 10.13 and 10.24.
From reviewing the logs, I think I've found where I can save the necessary time to get the 9 second pass. Shifts were completing at 6,200-6,300 and only 6,000 rpm for 3rd. This anomaly occurs from me running a shorter tyre than factory (305/35/20) and gearing is slightly off.
I'm going to make a few changes to the TCM and get it shifting at 6,500 which will hopefully provide the extra speed. These cars keep making power past 7,000RPM but as I'm still on the stock block and valvetrain, I don't want it lifting a head just yet.

Wowzer, that's moving some!
You can almost imagine UK air temps (vs Straya) would be enough to lop that last tenth off.
We're in our winter so as good as it's going to get over the next 4-6 weeks.You can almost imagine UK air temps (vs Straya) would be enough to lop that last tenth off.
Density Altitude (DA) is a key measurement when drag racing. The 10.13 was set in 1,100 ft DA so the equivalent of racing at an altitude of 1,100ft.
There's a track in the States that is renowned for its negative DA and it produces crazy quick times.

Does it not have a manual mode so you can shift at 7k rpm yourself?
It does have manual mode but the delay from when you click for next gear and timing it to perfection is extremely hard especially when you're doing 10 second 1/4 mile passes. The ZF8 is a very stout gearbox but manual mode isn't its strongest point. Plus, I don't want to shift at 7k RPM, 6,500 should be the sweet spot.Gassing Station | Readers' Cars | Top of Page | What's New | My Stuff
