And as proof of my statement, here is a factory dyno sheet from 1965.

That proves they underrated the engines. That doesn't prove the Hemi made 800hp or whatever that stupid tv show said it did.

 

Seems to me the best or the best put down just over 500 gross from Dodge and GM, I can't remeber any dyno runs for a Boss 429 so I'm not sure about the Ford being in the 500+ hp club in stock trim.

Yes, they did under-rate engines alot, but they would also exagerate HP claims. It was common place to do gross horsepower ratings which essentially was just the motor hooked to the dyno sans accessories of any sort and sometimes even using dyno headers. HP back then like HP today sells (a fact not lost on Detroit's Asian competitors as they did some tweaking and fiddling to produce higher HP numbers even though at that time said engines produced less in actual running configuration).

Anyways, I'm sure if you dynoed the 6.1 liter hemi of today, despite nearly lacking a full liter in displacement, it would nearly match or exceed the older engines output, or in the case of GMs own current LS7 - It would kick the stuffing out of any of GMs previous big blocks, even the famed LS6 and LS7 454's of yesteryear.

 

I have an odler issue of MCR, I think it was from 2005, with a reprinted article from 1970 on dyno'ing the Boss 429.

386 engine hp peak on a '69 model, somewhere are 6 grand even.



I also have a site where somebody dyno'd a stock ZL-1/4-speed Camaro and got over 425rwhp. Then there is an article of the Mopar Muscle site that dyno'd a stock, daily-driver condition, '67-spec Hemi GTX (w/ slushbox) at 354rwhp. Not bad considering the less than ideal circumstances.

 

Blah, blah, blah. give it a rest. Gears won't help the R/T even it there were gears available. The only thing that will help it is a diet or more hp.

 

yes but we are all forgetting the giant parachute they call a front end on the Chargers.....And Besides ti is still BUTT ugly!!

 

I forgot about this thread, I thought I was dead meat against an SRT8 I ran into at the dragstrip on friday but I handed him his lunch, I doubt he was all that happy. See my post about my dragstrip experience for a more detailed report.

 

Ray just curious, are you in Clear Lake? I travel 146 everyday in that area, wish I could have seen it.

 

Yup. Do you work where I think you work? If so, me too... Building 30.

 

lol awsome kill and nice letter

 

4N

 

I wish people like you and SixtySix would quit cluttering up this thread with facts and real-life results, this thread is for people like Metroplex to benchrace themselves into thinking the SRT8 is actually a hot rod Just kidding, awesome kill! And kudos to you for taking it to the track, just as it should be!

 

 

actually, after reading the performance numbers of the SRT-8's, (~425 hp), I thought it would master a mustang. Then I watched motorweek and saw the numbers they got with an SRT-8 and I couldn't believe it! Apparently they aren't nearly as fast as one might think. My feeling is it's a drivers race between an SRT-8 and a stock GT. Throw a vortech on and it's game over...

 

Whoa there buddy. You sayin a six can't hang?
I didn't get a SRT8, but some guy in an R/T thought he would beat me. Guess he knows his lesson now.

 

It's all that WEIGHT!!! At 4160 lbs, they are barges. Horsepower isn't everything.

 

Exactly! My other vehicle is turbocharged and has 515hp, but has the acceleration of a big pile of crap due to slight weight issues.

 

lol...

I got 500+ hp myself...wanna race for pinks?

 

Sure, because on paper, my extra 15 ponies will absolutely crush you.

 

As an owner of both breeds (Mustang and Charger Daytona), and obviously having driven both, I'd certainly say the Mustang GT is quicker and in handles a scoche better; but, not by much. With the right guy behind the wheel I'm sure an SRT-8 or Daytona for that matter would be more than a challange.
