Dyno-Tested: 2011 Dodge Challenger SRT8

[Sax1031]

This is what I saw a couple weeks ago. Supposed to be the same car that ran the 12.4x.



420whp/419rwtq

remember that car was an automatic, in the CHallenger specifically that makes a big difference. If I am not mistaken some of the better driver's in R/Ts, such as DodgeTony on stock 4 seasons were able to pull 1.8s-1.9s.

I'm with Evil Twin here, my money says this car is right on top of 430rwhp given the dynos we've seen and track performance thus far. That said, that still puts this thing right on top of LS7 hp territory and arguably this thing may be doing better than the LS7 in the torque department...and the LS7 is a real piece of work. Yeah, I think this car justifies the price, particularly since it is cheaper than the 2011 GT500 and likewise will almost certainly be cheaper than the 2012 Z28.

Also worth thinking about. If they throw this engine at the Charger we'll have a no apologies, rwd performance sedan priced meaningfully below the CTS-V as well.

is the edmunds inside line numbers corrected?? because the other srt8 dynoed 420rwhp corrected and 440uncorrected.

[Stew]

Probably not corrected. I am not a fan of insideline anyways. ANd I agree around 430 RWHP average looks like what we will be seeing.

So because they dont show every single bit of data from the IL dyno test..its a photoshop?

They are both real, just one is by a "common man" the other is by a well known website.

no, the insideline one isnt an actual dyno sheet that they print out. It looks like an artists rendering of what the sheet looked like when he saw it. Also, yes, because it has no other info on it it makes it suspicious at the least.

I am not believing the hp or the 60ft time on stock tires with a 4400lb car!!! Just saying.

could be the timing mark was wrong at the first 60' but bottom line they ran a 12.4 on the first day.....

Ok after alot of digging and searching , I found what made the diff from the 420 to 453 WHP

The InsideLine guys had a ............RED KEY

the head in the sand "nananananananana" approach.

[assasinator]

me = 400rwhp / 3500lbs = 8.75 lbs/rwhp

`11GT=365rwhp/3650lbs= 10 lbs/rwhp

07gt500= 435rwhp/3920lbs= 9.01lbs/rwhp

gen4= 305rwhp/3250lbs = 10.65lbs/rwhp ----stripper i know.

SS = 370rwhp / 3780lbs = 10.08 lbs/rwhp

392= 430rwhp / 4200lbs = 9.77 lbs/rwhp

392 needs 480rwhp to hang just even with me. im good. SS needs 432 rwhp to be even. 1998-2002 needs 371rwhp.

i have CAI since the dyno so it needs about 490rwhp now. SS needs ~442rwhp. 280lbs and 700 lbs hurts.

im not intimidated by it.

yea, 410-420 sounds about right. If this 392 actually made what, 530-550 at the crank, Dodge would be trumpeting that from the top of every hill they could find. They would not sandbag or underrate anything...
