They just posted results form the 14 mile drag in the One Lap of America race.
the SRT-8 did it in 13.141. Remember, this is a BARELY modified car!

Well, I don't know about "barely", but the mods to optimize track perfomance in some way offset 1/4 mile, so I would call it representative. Like heavier wheels, the cage, the weight of the fiberglass flares.

The car has a lot of mods, but most of them are related to suspension, which doesn't do much for 1/4 mile time. The 295 tires may help get the car going better off the line, but they add a lot of rolling resistance the rest of the way as well. Erich thought the hp gains were maybe 25hp. Anyway, the mods that were done, are readily duplicatable by any of us. Aftermarket exhaust is easy to do. It's not like he lowered compression, and added a supercharger (like many lap of america contestants).

Anyway - it's a nice time, and Erich is doing awesome everywhere he goes! I'm still hopind durability could help him capture at least a top 3 overall. He's in 5th overall now.

I think cleaned up heads and intake, CAI, gutted cats and removed resonators are more than 'barely modified.' I'm a little disappointed that they couldn't break the 13 second mark with those mods. Perhaps the stock SRTs are really about as good as they can get - and that's not a bad thing. By the way, if the DCX team is really using a rescued test mule C, does anyone know what's the axle ratio?

I believe he has the 3.06 that the rest of us have. However, the outside diameter of his tires is smaller, which should have the effect of improving his ratio over the rest of us.

And yes - it definitely was a C to start with - and an early one at that. He pointed out the VIN number to me and it was low enough to literally laugh. Wrong colors throughout the interior. Wood trim bits, etc. Lots of things left over from when it was a C.

Nah, not really. Keep in mind, this one event counts for very little in the over all.And the weight gain of the cage and tires and flares negates some of that. Nobodies going to really abuse the car in the 1/4 and risk the overall race. It's viewed as a lark by the guys, really. And these guys are NOT drag strip demons, they are pretty focused on road racing. Just wait til more cars are out there, with more runs. Then we'll see........ More data points equals better data. :)

Actually, it has a Quaife differential. So there's really no telling what ratio he's got. If I see him Saturday, I'll ask. (I forgot that fact in my earlier post).

The car is so far beyond stock that its #'s mean nothing. When you add that much weight and do that many mods, it just throws too many variables in the mix.

"That many mods"? "So far beyond stock"? Here's the list

+ It has the entire suspension from a stock Charger SRT-8, which includes 25% stiffer springs and everything that goes with it.

- 295/30-20 tires mounted on 20x10" custom made 3 piece BBS polished rims.


-40mm fiberglass fender flairs, Custom spoiler and front air dam for zero lift.

+Engine is stock 6.1L w/ cleaned up heads and intake manifold.

=Stock exhaust manifold.

+Gutted cats, stock center muffler, and the rear resonators have been removed.

+ Mopar CAI.

=Stock ECU/TCM with cat check disabled.
=Stock brakes with Carbotech XP9 front pads.
=Stock ABS/ESP. The ESP was partially disabled for the wet skid pad.



Theres the list. I agree, it adds variables. But I disagree that it's not representative. But of course, we can't know that til we have more owners run. Wanna bet a public "told ya so"? :) To be paid after, say 15 owner 1/4 mile times.:)

Justs friendly wager:)

Ditto what glhs said. Most of those mods have nothing to do with 1/4 mile times.

I'm sure it will handle a road course MUCH better than stock, but I don't think there's much there to improve 1/4 mile times. The changes that were made are easily and commonly done mods by many people anyway.

Hmmmm ...

Wow ... I got a 13.3 @108mph in my stock SRT-8 (K&N panel filter was present) (first time at the track as well, first time driving a rear wheel auto, only got 5 runs in)

Other than that, no suspension, no sweet tires (had stock all seasons)

Stock exhaust, cats, resonators, mufflers, stock intake, nothing "cleaned up"

I would hope that with some better tires and the exhaust done, that I'm in the 12's .......


We'll see ......

gutted cats, You think there were no ECM changes? Roll cage installed adding weight, cleaned up heads and intake aka ported and polished, are you kidding me, on some cars gutting the cats alone can pick you up 2 tenths and porting and polishing heads and intake can net a half second or more depending on the restriction. I'm sure they do not disclose everything they do to the car. A better hooking suspension, a suspension that hooks worse? who knows? Too much was done to the car to try to compare it to a stock SRT8.

Scott, yep, gutted cats, I really believe them about the ECM. There was talk back when about the SRT-4 they ran in 03, that it was so strong that it had to be a custom cal. Since then, store bought Stage 1s have duplicated it's times.

Same story for Stage 3. Everybody swore that the PCM programming that got the Extreme Lightweight (300-440 less, thanks to one of carbon pieces, lexan side windows, etc) to 11.8 would not be what the public bought.

Surprise, it is. Full weight cars are hitting 11s with very little additional mods.

So, yes, if Eric says it's same programming, I believe them. Not port and polished, "cleaned" is the term they used. They specifically said no porting or polishing.
Casting flash, protrusions, I imagine. And they did say the suspension is %25 stiffer than a stock SRT-8. As I said, only time and more owner slips will tell.

My contention is that it is compparable. See you in August:) By then we should have a represntative number of owner runs. See, I've been down this road before. :)
