This post is going to ruffle a few feathers but I assure you it is NOT directed at anyone in particular just a pet peeve of mine.
HERE is a time slip for a hellkitty Notice it picks up 27 mph on the back half on 9.70. My GN would pick up 26 mph on the back half at 19 lbs of boost Can i say that equates to a 9.80 run?
If I turned it up it would equate to an 8 sec. car.[size=78%]

Looks like a 9.95 to me, where does the 9.70 come from?
Pretty salty with a 1.5 60'. Obviously has a bunch once it gets rolling.

perhaps you should state what your point is? I'm a bit lost on this one.

My point is the people who run 1/8 mile and say their time equates to something 1/4 mile. So to make a point I am going the other way and saying my time equates to a 9 sec run.
There was another time slip at 9.7 but was too large. Thats where the 9.70 comes in.
1/8 time does not equate to anything. It runs what it runs.

Grab one of your timeslips and run the equation for your 1/8th ET and 1/8th MPH. It'll almost mimic your 1/4 ET and 1/4 MPH.

I don't agree with that statement. And definitely not in my case. In my case if the front half equalled the back half then it's a 9 sec car And ain't no way in hell.
Show me the time slip. IF you run the 1/4 and use the 1/8 time from that slip then OK .

Here's the post from my 6.7 at 105 run...timeslip included. Now...you'll note I folded the timeslip over. Reason being...is that I didn't want the locals to know how fast the car was. I coasted from the 1/8th...and it went through the 1/4 traps at 11.2. It doesn't take a rocket scientist to figure out what the car will do as far as the 1/4 is concerned. SMP has a short shutoff as Dan Keller and Justasix will verify. Dan Keller and I have stopped at 123...but it's a handful. We run the 1/8th for safety reasons.
Post your timeslip...and let's compare what your 1/8th MPH and 1/8th ET is compared to mine.

7.77 in the 1/8 at 96mph and 11.5 at i23 in the 1/4

You're a full second behind me at the 1/8th...and your MPH is far lower. MPH is indicative of HP. It all comes back to low gear tuning. You left alot on the table.

Yes I know but that is a street car IE no slicks. no race gas. 3800 lbs and drive to the track as much as 200 miles 1 way.
Low gear tuning won't help with no traction.
plenty of hp picking up 26 in the back half at 19 lbs of boost.
A non turbo car set up for the 1/8 won't run good in the 1/4 for example. or vice versa that is the point here tho. I have nothing to prove. but bench racing is fun too
Did you compare the wallace links.
-
Actually, low gear tuning will help with traction. Add some low gear fuel or pull a little low gear timing. Most don't know how to tune for track conditions. I don't need a calculator to know what 6.7 at 105 is. It's flat out flying.

If the power band is linear than the 1/4 mile estimates will be true. But if you have a 3 staged Nitrous kit or a big turbo Supra that takes the 1/8 mile to be fully spooled the calculator is out the door!

I'M not disputing that fact but i don't agree that equates to a 10 something in the 1 /4.
THe calculator [wallace link] shows hp in the 1/8 and 1/4 so if you add them together it equates to a 9 sec run.theoretica lly but I deal in realty not fantasy.

MPH is indicative of HP. I'll leave it at that.

Mph might be about horse power but the money that exchanged hands in my youth was about who got to the other end first. A dyno might be good for tuning and such but it doesn't get the power down or the vehicle to the other end.

True! I think your car is pretty linear. Your converter is well matched and the smaller cam makes it run very consistent.
I noticed with my low milage stock car. The more I hook the higher the mph yet with the modified car the more it spins the higher the mph. :hmm
-
A GOOD convertor that couples well at the top of the track will MPH better as well. I have a local that's not gonna be happy with the LU convertor he chose. You can't lock it...and he wants to track the car for the best MPH he can get. Gonna have a good pair of ear muffs on when he gets out of the car to drown out the cursing. This will be the 2nd convertor he's put in the car that I told him not too.
-

That is a pretty profound statement and means nothing by itself.
If you are saying you made x hp for y mph ok that's how much it took to do the run not necessarily how much you have on tap.
My car by your numbers makes 3 mph more than yours in the back half so With slicks and race gas tuning etc 105 in the 1/8 plus the 126 equates to 131 in the 1/4. Now add 5 lb of boost probably another 5 mph so 136+ in the 1/4. in theory.
actually my numbers are off a little 105 to 123 is only 18 mph in the back half so 141 in the 1/4.not 136 in theory

perhaps you should state what your point is? I'm a bit lost on this one.
I walked away from the bait... and keeping far far away from the bait.

the bait keeps getting more tasty but I'm gonna shake my head on this one...

Even I don't believe what I posted. I'M just manipulating numbers to prove a point.

Mike and Steve are funny as hell. Lol

I am just confused :D I am trying to figure out who Ron is needling because I cannot imagine anyone getting their feathers ruffled or who might argue with his contention now that we know what he is arguing about. Therefore, he has taken aim on someone.
I thought maybe he mixed his Canadian whiskey with Pepsi or some equally gross mixer :D
Or perhaps, a 9.95 quarter mile is a 9.70 when you cross the border due to the delta of the Coriolis effect as distance from the equator changes. OH, well, it generated some activity!
Most of all, I was impressed with his 140 mph time altho' I would have converted it to kmh to make it sound bigger

It's like people using a chassis dyno and then converting the rwhp to what the motor makes! :rofl:

Ahhhh the old woulda, coulda shoulda's :rofl: Run the 1/4 mile at the drags an get the slip. Let that do the talking.. Case in point we just ran a 9.42 @ 144 also with a crappy 1.5 short time. She has gone mid 1.3s.. So the would be a 9.2 anyway :player: :rofl:
-
Dan, that is an 8.9 all day long!! :icon_lol:

Maybe in Canada!

Cold air can do that! :)
