6.1L vs. 5.7L Manual Trans HP Ratings?
 

OK, here's a question to ponder. Chrysler shows 5 more HP on the 5.7 mated to a manual transmission and provides no discrepancy for the 6.1 mated to a manual tranmission. Does this seem likely that on the 6.1 HP is identical through two different transmissions?

i think i remember reading when the 5.7 numbers came out for the challenger it has something to do with the exhaust on the manual it is setup a little different giving you 5 more hp no sure why though

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

I read that the manual RT gets a "unique dual exhaust that has two low-restriction bottle resonators replacing the underfloor muffler."

I hope the different exhaust sounds like the 1970's, that would be cool. Well it really won't matter because i will probaly swicth them for Flowmasters or Cherry bombs.;)

Dodge has stated that the exhaust note on the SRT is at the highest maximum decibel readings permitted under state regulations. [sm=badbadbad.gif]

I assume that the R/T's will be almost as good.

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

It is wrong to assume that the R/T's will be almost the same in every way as the SRT8. That is simply a hope and prayer for those who do NOT buy the big dog SRT8.

If Chrysler did that , why would anyone buy the SRT8 ? They have to make enough of a difference to justify the extra $$$.

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

Agreed. That is why I qualified it by saying ALMOST as good.

Also, I was only referring to the exhaust sound. Everyone knows that the SRT is superior to the R/T in horsepower, braking, handling, and trim levels.

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

I could see this go in one of two ways. It is possible that the lower output through the exhaust was intended on the automatic for the R/T so then people would only need to use the more affordable mid-grade fuel over premium needed on the manual models, on the other hand as others have already stated the SRT is already hitting the limit as is with the laws, so then again it might not. I also have read before that the 5-speed W5A580's torque limit is supposed to be around 427 ft-lbs, so it is possible that they might have held back on the engine so then it wouldn't blow anything and since we know that the TR-6060 can handle far more than 427ft-lbs without breaking a sweat, it is possible the output might be higher.

most people are gonna go aftermarket on mufflers anyway so it wont really matter

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

Well, what matters is in the case of the magazine show downs. The extra output might be the deciding difference no matter how small it is. Also, some states have tighter regulations that would limit your options as well.

True we wouldn't want The Stig deprived of any hp when he is putting the challenger through her paces

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

The challenger would have to much power for the stig!:D

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

i doubt it seen him drive some pretty powerful cars around the track

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

I know, I'm just kidding.;)

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

Who is Stig and why does his mother hate him so. And where does he get a job driving fast cars... I want to drive fast cars:D

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

The Stig is the driver on a british show called Top Gear he takes all the cars they preview and puts them through there paces on the track

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

Yeah, that's a great show. They get away with stuff over there. They did a great show featuring the EVO as a budget super car. Really cool piece.

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

I wonder how long it will be before they put the Challenger up for a test with the Stig?

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

as soon as they can get there hands on one i am sure

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

I sure hope they can get one over there, but there a TV show, so they can.;)

RE: 6.1L vs. 5.7L Manual Trans HP Ratings?
 

i am sure some brits have there orders in on them
