Back in March on the 2nd day of the month I ran my new 2013 Challenger
many times up and down a side highway road less driven - old country blacktop. My car had 255 miles on the clock and figured it's had enough break in time.

This was my results for that day and it was right around 34 degrees outside, nice and cold.


Best run was 6.43 seconds out of 6 runs on same road

1st going east 6.50 left from just above idle
2nd west........6.56 left from idle
3rd east.........6.43 above idle not sure what rpm best launch
4th east.........6.50 above idle didn't see rpm
5th west........6.60 maxed out convertor to much wheel spin
6th east.........6.55 2500 rpm launch



Over the summer I tested and tuned, I was looking high and low for
any extra power, I had set backs , I was testing what works and don't work, I enjoyed
finding every ounce of power I could out of a few areas. The areas
I concentrated on was intake manifold, tb, cai, exhaust.


My mods are a lightly ported intake with "cool tape" under the upper intake and lower intake, fastman standard port tb, K&N cai 63 series kit wrapped with "cool tape" and lava wrap, also installed the much larger
AFE blue cone filter, installed the solo exhaust cat back system and
Lava wrapped the exhaust from the heads to the start of the solo exhaust
system.

Since the weather was pretty close to the same now as in March
and I feel there is no more to gain from these mods- a balancing
act of keeping low end torque and increases high end power.
I took my car back out to the same road. It was 33 degrees out.
My car has over 3,000 miles on it now.

1800 rpm launch from the brake and floored it, heading
west the tires scratched a little and I ran a 6.13

turned around, brought the rpms down a little trying for less wheel
spin, staged with 1500 rpms against the brake
and floored it, tires scratched just a little, little less then first
pass and I clicked off 6.10

I was happy with those two passes, maybe with a couple more passes
get a clean no spin launch I could bring it down some more
but figure this is proof enough that the mods do work.

definitely and improvement. Some things are a simply a labor of love and fun but how much $$$ have you invested to get from 6.43 to 6.10?

I cannot manage to beat the 5.12 second time on my stock R/T with the 6 spd. Especially now that its colder out. These F1's won't hook up worth a damn ... which is a shame because the car runs noticably stronger with the lower temps.

I'm consistently in the 5.4 second range with traction control on. If I take the traction control off my launches are terrible with lots of tire spin.

I admire all the mods and data you try to collect and share. Do you have any plans on getting a supercharger or turbo?

Well I have lost count, it's a lot thou, I would hope some will find it useful, I have spent lots of time
and money just tinkering. I do it for fun.

At the moment my next step is a 3600 FTI stall and some blue tops and look into
the tranzformer. I would like to see how far can I go N/A, then if my interests
are still there maybe supercharger.

The 3.6 needs help down low and I think
once I'm able to launch near the torque power band (with a stall)so the car is really getting a
chance to move off the starting line then I can test out my
other ported tb that showed more trap speed and test my other two intake designs
that provide more pull on top end and test out my h-pipe on the exhaust again.

I already know my other tb, ported intakes and h-pipe killed low end torque
in a bad way, they also brought the top end alive. If I have
serious issues with traction next year running the 3600 stall
then I think I might be able to use some of my other parts to lower
the torque a little to get the car to settle down on the line while
providing a little more power on top. Another balancing act.

Of course I could throw some DR's under the rear and stick it full throttle off the line
but that's to easy. I'll see what next year brings, I think the stall will
show some serious e.t. reductions.

Fti converter was going tk be my next mod, look forward to your results with it.

with an exhaust system and Diablo dcx intune, I was able to do 5.82 in cold weather

What was it before? Thats a good time.

Most of it would have come from the intune just based off what
I learned on my car, at least on my car
the solo isn't worth anything performance wise, it hurt the low end some. I know if I
put my stock exhaust on right now my low end will pick up, I might be able to get
under 6 sec. 0-60, just a guess I could dip under that, any help with
more flow on the exhaust just slowed the car down.

best was 6.03 with just pypes exhaust by itself.
