Mildly Modified Hellcat Goes 198.9 at the Texas Mile!

[ostmike]

Congratulations to our email tuning customer Patrick H. on a new PB at the Texas mile!
This is a very mildly modified Hellcat and he was only a few MPH off from Hellcats running with built engines, aftermarket superchargers, N2O, ice tanks, and E85. Tuning is certainly a key component but just as important is a detailed oriented customer who knows how to properly datalog and supply excellent commentaries. At OST we have certainly been blessed with many talented remote tuning customers!

Here's what Patrick Had to say:
"Just came home from the Texas Mile this weekend.
This was my 11th Mile event, and the 4th with my Hellcat.
Last March I ran a best of a 192.5 mph.
My combo at that time was 10% lower pulley, 95mm throttle body, LMI intake, 1050 injectors, cat deletes and 3.09 rear end on 93 octane with a little Boostane as a safety net
Mike Doban with OST Dyno has been tuning my Dodges since 2011, and my Hellcat is no exception.
This weekend my combo had been augmented by a 3.17 Litens pulley, Interchiller spacer plates, and MS109.Mike was busy at a private track day Friday so I was left to my own devices tuning wise.After a couple of initial runs with last March's tune and good datalogs I made a few small changes that netted me a 194.9.
Mike was back online Saturday and his first tuning change netted me a 195.1, followed with a 196.2.
Sunday morning was warm and humid, but I still ran a 196.5.
I loaded Mike's last tune and ran consecutively a 197.5, 198.3 and finished the day with a 198.9.
Not too shabby for a moderately modified Hellcat Challenger!
FWIW, I was the fastest stock supercharger Challenger Hellcat this weekend!
Thanks Mike!"

You guys have your stuff straight for sure.

That's cookin.

Great job! I bet you found that 23 degrees of timing in a full mile race was backed down and she ran a faster top end.

I'm not quite sure what you are saying here but I promise you I would never run 23 degrees of timing in any Hellcat combo at WOT.

 

[AlleyCat]

I think they run better with a little less timing Mike. And by the way your demon c made 1010 torque to rear wheels with stock blower.

That is a very nice run!

As a baseline, do you have where the truly stock HCs were running that day? Do you happen to know what the DA was? 180-185mph for stock is typical from what I hear, but I've never made it down there to know for sure.

To put that run in perspective, up here at 8000-8500DA in Colorado, I'm running 174-176.

Stock Hellcats were running in the 170's at this event.

Wow, 'not sure what to make of that...


I guess 170s covers a broad range...


Regardless, your run is nice, you're so close to breaking out of the 199 class!

Here's a link to the final MPH numbers at the event. There is a Hellcat at 188MPH which is another customer of mine with a ATI 10% overdrive lower. There is another Hellcat at 181 mph but I do not know the mods. All the other Hellcat are in the 17x MPH range and I assume that those are stock. http://www.axwaresystems.com/axstorm/liveresults.php?op=finalresults&clubname=USMILE&op2=on

Very cool but to me, Patrick’s car seems a little more than mildly modified: Injectors, pulleys, throttle body, interchiller spacer plates, custom tune, rear, etc.? I’m thinking there goes the warranty!

In the Hellcat, Demon, Trackhawk world this is mildly modified. Now if he was running a forged stroker engine, ported or Thitek heads, 10% lower and a 2.65 upper, a cam, decent shot of N2O, headers, ice box and a Whipple or Magnuson then I would say he was highly modified.
