Appears that Buck70 got one done. Was surprised to see that it came up "short" at 265/256. Ratings are 330/315. Thought Chrysler under-rated those figures. Of course, it depends on other factors, and the dyno. But, I thought it was worthy of posting. Lots of SRT-6 still have them breaking in.
If we ever get a dyno, will post. Buck70 can comment further on his numbers and his ideas regarding "common" statement... OK Buck, you're up. Zis very common as it's not yet broken in? Or, is the SRT-6 more de-tuned than an AMG SLK32? Splain it so we's can understands....
BTW
It made 265/256 on the dyno, which looks like about 20% loss<> very common. The blower does have AMG cast into it under the plastic cover
and there is a clutch on the blower drive too.

Hey
You assumed it was mine, sorry I wasn't clear. The one tested belonged to a member of the Viper club, it was his wife/girlfriends car. It was the convertible that I mentioned, with the small trunk, "luggage won't fit", ours is a hardtop.
On the 20% comment:
For clarity we are rated @ 330 <>@ the crank or BHP
The RWHP <>rear wheel is typically 20% less from drivetrain loss.
Tranny/U-joints/rearend etc.
The other #'s game to watch is net<>gross on BHP
Old Hemi's were rated/listed gross HP<>without pulling the water pump
alt/AC/PS etc.
New Hemi's are rated Net, which is around 30 HP diff IMHO
BUT, I haven't seen much of the under rating that used to happen
during the 60's for Ins reasons etc. they seem pretty accurate now.

A good example is my stroker Dakota
On the (engine) dyno with the small cam it made
360/460 BHP/BTQ
It wasn't turning the water pump, but it was turning the oil pump, so not a sump dyno for full gross, but def not net from having no belts on it.
In the truck, on a (chassis) dyno for RWHP/TQ #'s it lost 90/90
for a 270/370 output @ the rear wheels. Drivetrain loss is typically 18-22% and the rest would be the accessories when the belts are on the motor.
Still roasts the tires @ 30 MPH but with the 4200 lb truck it runs mid 13's

Strange, I always thought the BHP was measured at the wheels not the crank. Ah well, ya learn something new everyday. Wheel dynos of SRT-4's come out out pretty much spot-on at 230HP/250TQ even though their literature states BHP as the same. And, rumor had it that they were "conservative" estimates for insurance reasons. It's a front wheeler, so maybe the losses aren't as great on them (which would make some sense) than RWD or AWD vehicles... Wish the manufacturer would rate it "like it is" shoing BHP at crank, drivetrain loss, and net wheel HP.

What were the conductions when the pull was made? Heat and humedity play a part. If it was hot and humid you won't make as much power as compared to cool and dry conductions.

Temp was 85 RH was 25% SAE was 1.02

How were you able to bypass the 5,000 rpm cut-out caused by the BAS/ESP/ABS circuits ?

A chip on this things make all the difference in the world. Gotta reallize they have to tune for "in case shit", which means people not paying attention, and putting 87 oct in it.
I know the SLK32 with a chip intake, and upgraded intercooler water pump is pretty bad ass ( like 13.0 area ). The X-fire should be slightly faster.
Honestly, I'd just put a bottle in one... If I didn't have the need for back seats, I'd concider getting one, and it would have a bottle and DRs. peroid. A 50-75 shot would do amazing things to cool that blown motor off.
