Did DW230's number 1000 hp number go over EVERBODY'S head(s)?

What yrs truly is pretty sure he was stating is:

 ALL you landspeed DREAMERS need to actually experience  Salt Flats racing and find out on your OWN what your rig really can do.

More than one experienced Elmo/Bonnevile racer  thinks a few of these salt flat posers  don't have the cojones to even show up with a race car.

Bob, you know I love your car,,, but my E motor on Gas will never have the power you have,,

Did you weigh the 4300 lbs for that 219mph run with the 630HP motor in order to plant the power to the Salt or the keep the rear from coming around and spinning ?

With me in the car the total weight is 3600lbs,,, 52% on the rear,,, I do not think I will over power the the Salt (break traction) in 2nd, 3rd, or 4th. Gear,,  will I be to lite to keep the rear from wanting to spin and pass the front?

Since I race in Standing Mile and 1.5 mile venues backe here,,, this weigh works real good,,, but yes I do have provisions to add weight  very low and centered in wheel base or slightly back of center.

Hey Bystander,,, I sure as hell hope you where not calling me a poser,,, or doubting my cojones... as you don't know me,, and I sure as heck hope  your smart Acura comments where not directed at me,,,


..also the reasons some of us back east have not been on the Salt yet with our race cars , may very well be a matter of time, distance and money,, not lack of cojones.

Leave Bystander alone.  He's old, misinformed and crotchety.  He thinks you're still taking votes on the paint scheme.  See you in August.

  Cajun... I have used the 'Bonneville Pro' computer program sold by RACING SECRETS .COM for many years
for the 222 Camaro. You can input all your specs that you know about your car and engine and you can figure
out some you don't know after it computes.

 Inputs are track conditions, elevation -barometer-temp-ect. Track --one mile asphalt--El Mirage--Bville 3 mile
and 5 mile ect. weight-tire size -gear ratio-trans ratios- frontal area- drag coefficient-lift coefficient- rpm --hp--torque, after inputting data click on TS [time slip] and it computes speed in hundred of sec in time--distance traveled in hundreds of a mile--mph and acceleration rate what gear and rpm.

  Inputting Stude data 793 hp- 595 tq at 7000 rpm 3600 lbs-19.5 frontal area .3 cd- 3.3 gear ratio 91.4 tire roll out [29'' tire] and 1 mile track is 201 mph

  For bville with 793 hp and 5 miles-- 235 mph

  Bville and 200 mph---510 hp

 :? :? :?  What does any of this have to do with "ground effects".  Aren't there enough other threads for  general chatter ?   :? :? :?

    John, I am not familliar with that program but find it eerily close to the results I posted (and my comments's from Bruce Geisler)  in my earlier post.
  Cajun, the added weight is needed for the higher speeds handling and low speed traction.  Terry Hunt's stude ran (I believe) 235 mph with a SBC D motor.
  Efenn, sorry, just answering questions.
  After a few hundred post's you will get used to it......................... :cheers: :cheers:

  Bob... I started with your hp figures and weight using the inputs for the 222 camaro already in program.
I had to reduce the frontal area from 20.5 to 19.5 to get your speed, or I could have reduced the CD and left
the frontal area the same.

  Its also easy to change hp figures by mutiplying + OR - [ 1.1 OR .9] or whatever 2 or .5 then on closing program ask if you want to save inputs, no in your guys case, so program goes back to 222 data. Cool :-D

Not wanting to reserrect this topic, cause it's not cogent, but how about the kid in the '40s that smeared GRAPHITE all over his Soap Box Derby racer and his FACE AND HELMET to cut down drag.

As I recall, he WON the Akron event!

How about with 'Production' body classes?

I've seen lots of 'em with their noses slammed, bumpers on the ground, and tails in the air...

Is that better than a level, stock ride height?

Not if you're otherwise acceleration limited, AKK and Stan!

But I will agree that if the high aero downforce Landspeed cars are spinning their wheels w/o getting full throttle, I'm not sure there's an alternative.

I spray Pam on the lower half of the bike ... but not for an aero advantage.   Makes clean up a lot easier.
