This explains a lot
« on: June 17 2018, 11:05:03 PM »
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.

A lot of broken parts does not make you a racer; it makes you a slow learner.

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.
