It is always nice to read about "what I have accomplished" statements when it has nothing to do with the topic. If you want to talk about dragsters, please start a new thread in off topic, I'm sure you will have plenty of people discuss the subject with you, but not here.
Great job, please tell me more about your daily driver 7.x second dragster. I love the story.
I WILL TAKE YOU VERY SERIOUS!!!
Vance, is the subject of this car a completely stock OEM vehicle? If so, I sincerely apologize; if not, then you are once again completely out of your depth in this discussion. Perhaps you should just stick to tiresome lectures about how great parts only come from Japanese vendors or how the stock intake system is never a limitation.
I can understand your resent meant towards "what I have accomplished" statements - Have you personally EVER actually built a fast car? I mean for real, in your garage, not by just writing checks or in theoretically in some internet argument?
Did I say the back-half car was a 'daily driver'? I have to wonder if your misrepresentation is an honest mistake or if you are just being petty (again). Anyone who actually had any practical knowledge of performance cars would have read my description of it as a 'back-half' car as a clear statement it was not intended to be used on the street.
Just to clarify, the EF we threw together was street legal, with an inspection sticker and plates and ran on pump gas. Naturally Aspirated. And, yes, it would run 11s all day long.
Lastly, my discussion about drag cars is entirely relevant; after all, that is the subject of this thread: a car used for drag racing (both on the track and on the street apparently). So, no, Vance, thank you so much for your advice, but I will not "start a new thread."
------------
To get back to the drag car that is the subject of the original post, I am very skeptical, but have a hard time saying outright that it is impossible without knowing what all of the modifications (to both the motor and the chassis) are. BTW, nitromethane is very difficult to use in a motor that is going to run for more than a few minutes. It is very corrosive, attacks fuel system parts and even breaks down the oil in the engine rather quickly. Even in partial mixtures, it is just very hard on the motor. It is not a good solution if you want your (in this case expensive) motor to last very long. But, I see people make foolish choices every day. . .
So, to attempt to address this in a logical and practical manner, lets start with the assumption that, as a dedicated drag car it has been gutted and is very light. I think that is fair, as any of us with practical performance car building experience would start with that. Pick a number you personally are comfortable with: 2700lbs/2800lbs/whatever. As a benchmark, with perfect efficiency, a 2700lb vehicle needs about 335 whp to hit 11.75. (I know this weight number is very low, but lets just use it as a starting point)
If it is a stock long block, then the claim does streatch credulity (to be polite). Bolt-ons just aren't going to get you there.
With very high compression, cylinder head work, custom intake system, cams, custom headers, custom gearing, etc. it is still a long shot but is possible. Not likely, but possible. It also occurs to me that if you had a custom R&P and a 9K rpm redline, you could get a pretty high net gear ratio and still theoretically trap at the required speed. Wheel sizing could also help the net gear ratio.
With all of that and more displacement, it starts to transition into the realm of believability.
That said, - and this is directed at the OP - I believe that if you are going to make a claim to have either done something generally considered impossible or to have built the fastest/biggest/best of anything, it is up to you to provide reasonable evidence. A time slip is a good start. But without some explanation of how you did it, it is not even close to being sufficient if you expect to convince a significant number of people of your claim. As an example, my very first turbo nsx could run 11s on street tires if I granny-shifted the whole way. So, a time slip and a video of that car would not prove much if I claimed I did it with a normally-aspirated motor.
I guess it boils down to this: if you truly are running that fast normally-aspirated and don't care if anyone else believes you, then congratulations. If you want us to acknowledge the accomplishment, you need to provide more information. I hope you chose the later, as I am always eager to learn more and add to what I have picked up during my experience in building performance cars.
