Re: SS/E 2008 Mustang at Atlanta
 

I only tried to add 150 hp as that is the # you are throwing around. That is why I asked if you thought it should weigh what I posted. To answer your 150 hp question NO I don't think any combo is off by 150 and from this post neither do you? What 3 valve motor does Ford or anyone else make that is rated @ 510 hp? I hate to assume anything but I would venture a guess that your talking about the regular shelby that is factory 500 hp It has bigger valves (4 per clyinder BTW) more cam and more compression same cubes but you want the Cobra jet rated tha same?? While the CJ certainly shouldn't be 75 hp less it should be less. As for underrated combo debuts 94-98 LT 1 comes to mind 1st, then the 62 327 Corvette motor and I think I few mid 80 305 combos have had a ton of power tacked on over the years. Also the original Cobra jet as 428 has had plenty added to it over the years. I bet the new Cj's couldn't hang with Mr Pond Mr DeArmond o Mr Sorenson or Mr Barton or Mr Fiacci (sp) @ 450hp. Pure speculation on my part but time will tell I bet

In reading through these posts, it never fails to amaze me that supposed S/SS racers get on here and throw out specifications based on assumptions and not easily found facts. Maybe that's a clue into how there own program is run.
For example, the engine in question (2008 Cobra Jet package) is NOT a 3-V engine, it is a 5.4 4-V engine, very similar to the Shelby engine, rated 500 FP per OEM until recently upgraded to 540 HP w/ tunning upgrades.
Here is a snap-shot from the NHRA 2008 Ford engine blueprint showing how many valves:
(note the 425 HP 330 or 5.4L 4-V is 49 CID smaller than the 510 HP 4.6L 3-V)

Re: SS/E 2008 Mustang at Atlanta
 

Okay I've been reading this and I don't see any proof (link, Video, ect...) of a 146 mph pass. Did I miss something? To me if there's not a video or a creditable link that shows a 146 mph pass it didn't happen.

Re: SS/E 2008 Mustang at Atlanta
 

A/SA,
Check the class guides before you roll out here with your little Ford rant. The little 281 motor with the three valve head is in the nhra blue print sheets at 510 HP. The extra 150 horsepower figure comes from the Ford folks, sorry you can't accept that.

69 Cobra,
There have been thousands of passes that you have not personally watched or seen on video. You don't believe they happened either??? Sorry, no amount of huff'n puff can change this cars numbers.

Dyndorf,
Leg to stand on? The old motors did not have blowers or the technology that your little cj has. 140+ mph on it's third time out gives us a leg to stand on and gives you no defense for this car.

Re: SS/E 2008 Mustang at Atlanta
 

Hey Bruce, I have a question just out of curiosity and by no means do I want to offend you in asking this question. But Why should the NHRA make the CJ's add weight before they've done any damage to the index? Sure they seem to be capable, but they really haven't stepped on any toes yet.

Re: SS/E 2008 Mustang at Atlanta
 

Bruce,
No huff'n and puff'n here! I'm just calling BS until you can show me that one made a 146mph pass. Also you keep talking about the Roush P-51 which is rated at 510. That is a completly different engine with a much better intake, heads, cam, and compression combo. Its like comparing a comp engine to a stock 327 2bbl.

Waiting on that link btw....

Re: SS/E 2008 Mustang at Atlanta
 

Cutta,
nhra is meant to make a good faith effort to determine the true horsepower of a combination before it issues it's factored Horsepower. In this case they just took Ford's word for it and now we have a 750+ Horsepower car in Stock.

69 Cobra,
I made reference to the 510 motor as a method of comparison one time. I called the little 281 motor the cousin of the 330 motor and said the 330 motor should given the same Horsepower. I still believe that. Did you see the first 200 mph run in nhra history or how about the first 286 mph run in nhra history? No BS they really happened.

Re: SS/E 2008 Mustang at Atlanta
 

I think the point that 69Cobra is trying to make is that the 146 mph run can be verified by nothing more than hearsay at this point. The other runs to which you're referring were witnessed by many people and well documented.

I just want to emphasize that I'm not criticizing anyone's viewpoint.

For what it's worth, I think they will ultimately need to be factored, but I don't know if they're 85 HP underrated. Should be interesting at Indy when the Challengers and Cobra Jets line up...if the Chally's are done by then.

Re: SS/E 2008 Mustang at Atlanta
 

Do you think they did that with the P-51? I don't see anyway the P-51 really makes 500hp. But did nhra make a good faith effort to determine that or did they just take Roush's word on it. To me its just advertised hp which is a selling scheme for Roush. How about the L88 motors? I read an article awhile back where they said those are very capable of making 800 hp and what are they rated at 430?

No, I did not see the first 200 mph pass or the first 286 mph pass. Probably because, the use of photography or videography was not commonly used by the general public at the time. But today it’s April 22, 2009 and you can't piss in your back yard without someone getting it on camera. You are claiming that this car makes 800 hp and this and that based on a phantom pass that nobody has seen. That's why I'm just saying until someone can show proof I'm calling BS!
