this is all in fun So, in saying that: If you never put it on a DYNO and you never take it to the track.....then the horsepower number can be whatever you want it to be Very well said Rick
Yes, I agree, three types of horsepower: 1. Dynojet: actual horsepower 2. Desktop Dyno: virtual horsepower 3. Mental horsepower: whatever you think it is rk p.s. NOTE: Horsepower ratings above are listed in least horsepower to most horsepower order.:deadhorsepower
In my minds eye, I can see what you are saying, but I can't say it right 'cause my tongue keeps gettin' in the way of my eye teeth! rk
Thanks, Draggon13. That was good info. Guess there's another kind of HP: misremembered. I was thinking stock '72 302 was 160. I had a '66 Mustang 289 2V that was rated at 200 (if I remember right). Knock off 20% and that's 160 at the wheels. I'm looking for a little more than I had with the Mustang. Think I'll be looking for some GT40 heads.
Try this little item here if you really want to hurt your feelings. H.P. of what the motor makes is useless if it ain't on the ground. http://www.gtechpro.com/rr.html
Why do you get a rash and a crap when you ask a simple question like this? Not everyone has a stroker, 351, or big block in there, and many of us have stock 6 or 8 cyl engines or maybe a couple of upgrades, and just want to know. How hard is it to just tell the guy, "you have 140+/- stock, plus maybe 10-15 more from your upgrades" and leave it at that? By the way, desktop dyno only gives 20-25 more HP for upgrading to GT40 heads. It sure "feels" like more than that, but that will give you an idea of what to expect.
I have a buddy that has a chassis dyno, He has told me many times about someone coming in that thought they had 500+ H.P. He said the look on their face is priceless when they only spin the rollers up to about 275. Truth is 90% of the people have never even felt 200 H.P.. We got a new 1 ton pickup at the shop in 95, I cant remember the H.P. rating, But to the wheels it only made 65 H.P. But as i said if it ain't on the ground it ain't nothing but a number.
You forgot one: 4. Seat of your pants Horsepower: The power you "feel" your car is making judged by sitting in the seat while car is at full throttle.
I had the race car engine dyno'd. Wasn't sure on where it would put the needle. Came out at 574. something. I thought I might push the 6 figure harder, but hey that's what she wrote. Car ran a best of 9.75 1/4 mile, run all day long in the 9.80s. I'm still tuning the rest of car and have to see how that goes. So yea it goes off seat of pants or time slips. Again, whats in a number? Puts that smile on your face,,, YOU GOT IT!!!
I agree, HP is very hard to judge based on "seat of pants", but we have enough info to give the guy a ballpark figure that, sorry for him, was way under his estimate. But that is how we learn what HP feels like. Get a ballpark figure, add to it, and keep shelling out the big bucks. Isn't THAT the name of the game? And, I cannot stress enough that in our small/light cars, 160-180 HP can be A BLAST to play around with!!! Sure beats that 1.6L Nissan Sentra I drove for 160,000 miles...
not to be rude but I just wanted to know how many horses my car would have I didn't want people to rip me a new one sheesh...
You missed another part of the equation. Starting also with the 1972 model year, Ford lowered the compression ratio (by a full point or more) and retarded the cam timing (4*to 8* for most V8's). Those two things also accounted for some of the 70 hp decrease from the 210 rating to the 140 level. It wasn't just in the method used in measuring the output that dd it.
I don't think anyone was "ripping" you I certainly meant nothing other than a little humor in my comment and I think others did the same. This has been good, fun conversation......I think When you ask that question, your gonna get a variety of answers.....none of which are likely correct; in the ballpark.....sure. To many factors go into "horsepower" for someone to give a true estimate. You might pull 200 ponies at the flexplate.....you might pull 180 only one true way to tell and even DYNO's are different. My motor has been dyno'd a few years back.....I have never told anyone the numbers; not cause I am ashamed of them; its just something I wanted to know, cause it helped increase my seat of pants dyno as scooper said, that horsepower in these small cars can be a blast! and thats what its all about.....having fun with it. If I offended you.....I sincerely apologize.
I've got two pair of early 351W heads that are up for sale. First pair are bare and different casting numbers, C9OE & D0OE, I have not been able to find any info saying they are different, but somebody here might know. The second set is complete with valves, springs, screw in studs and guide plates, matched casting numbers, either C9 or D0, too cold to check tonight, but can do so tomorrow. Also they are missing one screw in stud. Asking $100 for bare pair and $200 for complete, less one stud pair. Plus shipping. rk
