Re: New record in awd??
don't get me wrong...i know its still a syclone...but i'm thought the general consensus is that v6's and v8's are in a bit different classes....
but i also know that it isn't the power thats really holding these things back

Re: New record in awd??
why do you say that?
Mike, U got that right
AWD is the real challenge.

Mike, U got that right
AWD is the real challenge.
No intesion to rack U down, Think U missunderstood my coments on Mike Renz input..
The challenge to get the SyTy going fast eint the problem to make power despite V6 - V8 engines or single or dual turbo´s, N2O or not.
It all comes down to get the power to the ground, hook up and go straight. And thats a big problem..
Ask Hoovers, Hess, Bullysyclone, and other thats got their Sy down to low 10 OR even nailed a 9..
Still only one confirmed Sy AWD that managed down in 8 sec runs..

Re: New record in awd??
Not true ....if hoover was at the same altitudeas robert he would have been in the 8 and robert never ran 8 the whole time he was in the states...right?

IF is a magic word, IF it had´nt been for this or that...........
oldest exuse in the book
And speakin of Robert trying to take the 8 in the state´s, not that old story again, thats history

Re: New record in awd??
Come on guys, I'm a newbie and I know that math is not always exact. Sometimes there is just to many variables to calculate or have a perfect speculation on 1/4th mile runs. We can always have a mathematical theory or figure but that does not mean it will hit that exact number. I have respect for anyone that can maintain modded SyTy, 13s or 8s.

Re: New record in awd??
Yes "lithle big man" math in teory and practise can be 2 different things..
I agree that altitude does affekt an NA engine big time, but its different with turbocharged engines.
Found this explanation.
Altitude and Engine Performance
Sea Level: Units of Pressure
--------------------------------------------------------------------------------
Inches of Mercury = (in. Hg.)
Atmospheres = (atm)
Kilopascal = (kpa)
Millibars = (mb)
Pressure equivalents to: 1.0 atm = 29.9 in. Hg. = 760 mm Hg. = 101.3 kPa = 1013.25 mb
Atmospheric Pressure = 14.7 psi & 13 cubic feet of air = 1 pound
Power Loss due to Altitude
Air Density decreases at a rate of 2.9% - 3.0% for each 1000 ft. of elevation above Sea Level. See Standard Atmosphere below for background information.
Naturally Aspirated: Atmospheric Pressure 14.5 psi (It's hard to ride at sea level 14.7 psi)
Atmospheric Pressure @ 9000 feet = 10.5 psi
Pressure Loss = (14.5 - 10.5) = 4.0 (4.0/14.5) = 27.58 % @ 9,000 feet
Does a Turbo lose power with altitude? Yes!
Atmospheric Pressure = 14.5 psi, Boost = 10 psi, Total Pressure = 24.5
Atmospheric Pressure @ 9000 feet = 10.5 psi + Boost of 10 psi = Total 20.5 psi
Approximate Pressure Loss = (24.5 - 20.5) = 4.0 (4.0/24.5) = 16.32 % @ 9,000 feet
This is calculated for 9000 feet! ! ! I hardly think Hoover did run a track at that level??
This last sentence is weeery importent tooo
The power loss due to altitude is much less with the Turbo. The critical difference is that you can flip the switch on the Turbo to 15 lbs boost and get your sea level HP!!
This is Math

Re: New record in awd??
While we're on the subject of math, there is a neat little formula that says with an optimized combination, quarter mile trap speed x ET equals 1320. And thus, 1320 ÷ mph = potential ET. And, 1320 ÷ ET = necessary trap speed to achieve that ET.
If you look at some mild SyTy builds, you'll see that they tend to trap and ET very close to the optimum numbers. Example: 13.20 @ 100mph is very common.
But, look at the fastest passes. The 8.98 @ 155 pass: 8.98 could have been run at ~147mph; 155mph was theoretically enough for an 8.5 ET. And, the 8.85 @ 160 pass: ~149 mph should have been enough to get that ET, but it trapped 160 (which is theoretically enough to go 8.2's).
This tells us that at that level, since even the fastest AWD SyTy to date is far from running optimized ET vs. MPH. There are deficiencies in the chassis, drive line and/or suspension that are holding it back from optimizing ET in relation to MPH.
Other trucks have certainly trapped fast enough to run 8 second passes, but have not been able to sort out their set-ups sufficiently to run the ET. Its not a mater of making the power, its the rest of the combination that's holding them back. I agree with Anders that the AWD platform creates a tremendous obstacle at that level. Hats off to the Swedes for being the first into the 8's; it took a lot of hard work and R&D in uncharted territory to get there.. As for everybody else who's gunning for them, it isn't going to be an easy task; making the power isn't the issue (several trucks have trapped fast enough), but rather a matter of figuring out how to effectively put that power down.

Re: New record in awd??
Well I dont have a confirmed "1/4 mile" time but with the 1'8 mile times I have been low 10's high 9's would be just a trip to a 1/4 mile track away. And it is all in the suspension. I 60' in the mid 1.4x range all day long on wore out old nitto drag radials. And can put regular radials on( higher than 200 tread ware and only lose down to 1.51-55 60' range. I understand there is a difference between 700 and 1200 hp. But I will get it to the ground It isn't rocket science. Just have to know how to ramp the boost in and a couple of other little tricks thats all. Now how far did that wing get robert?LOL

Re: New record in awd??
Seem U got a good build on its way will be realy intresting to follow Ur development. Seriusly
And yes, its a bit different between 700 and 1200 hp, also its no rocket sience toget power to the ground despite this all with lots of power and AWD seems to miss someting? about the "caveman sience"
Oh the wing, haha It carry´s Robert "straight as an arrow" and it will "open up the pearly gate"
(8,7x or lower), but season is ended over here and starts in may -10 so U´ll be ahead of us here..
