While I have no hard core racing facts to contribute in my basically stock RE, I can qualify with an absolute certainty hpindy Hit it dead on with his post on efficiency and heat related post, based on the fact that all flowing gasses, “All” are subject to volume reduction in a given space ie chamber, blower rotor area etc if heat is increased period. This is all based on charles law and boils law. If someone can navigate around that physics law I am all ears. Now that I high jacked the living shit out of this post I would like to thank everyone for educating me on what seems to work and what doesn’t. After all we all seek the
Powerful hp grail no?. In the heated debate no pun intended all posts hear have some merit. The one common issue with our boosted cats is efficiency, and when it peaks. To much to soon and traction is the issue, loose the 60’ and it’s a bitch trying to get it back at the high end. It comes down to a given area (note area) that is compressed at at a given temperature because two identical volumes are actually different volumes if they aren’t the same temperature. Mon through Friday I deal with measuring volumes of gases while it may not make me an authority on internal combustion thermal efficiency properties it dose yield a certain given fact that hpindy pointed out air quantity reduction with heat not to mention if our knock sensor friend steps in and pull back some timing. The flows I measure are on a ultrasonic, orfice, turbin, and (Rotary basically identical to our blowers)
All of these gases are measured with these
For uncorected volume then a corrector takes this a step further and corrrects for supercompessibility ie: temperature and pressure to yield a real corrected actual volume. Soooooo, All of you folks are right in many ways just my worthless .02
And for what it’s worth I was popping Skittles in my mouth while reading all the posts, no shit really. Reading the passion here makes me wanna say aw F it screw the warranty, call one of the 3 or 4 hard core tuners that will get er done and find out what a RE can take. Hope I can find the gumption to kick it off. One last thing. I have absolutely learned a boat load observing from the side line with all the posts hear and at the other site, your all winners. Sorry for the long high jacked post.
The watch full observer
There are many ways to look at this, the older I get, the simpler approach I take. There are many examples of hellcats actually slowing down with whipples and KB. I know of a Demon what was running 9.0s at Hemifest at ran 9.34 with a KB in Michigan (a few weeks later).
Many people have bought the whipple and KB, no time slips to date have been posted quicker than 9.5's. Yes, the hellcat with the race motor and ported blower went 9.1s. At some point, you have to call it as it is, in this case, the Whipple and KB are the wrong move on a stock motor, stock weight hellcat, IMO.
Maybe it shines on the street and at 1/2 mile events, IDK. Telling the truth causes issues today, the truth is something that many do not want to hear. I think, I can kill all the whipples in a 1/2 mile events, since I am much quicker than them in 1/4 mile. Do I want to run a 1/2 mile? No, I will be around 200 MPH, even with the cage, it is too fast, there is a guy that died in Florida doing these events, a problem at 200 + mph is hard to walk away from.
However, the spin is the whipple shines in the 1/2 mile, so lets find out, I have a stock drive train (motor has aftermarket pistons and rods), stock A8, stock rear, stock supercharger, but I have no takers on the the call out.
I will be at Atco for the MSHS event ( I am not 100% sure of this but it looks that way), if any whipple or KB cars want to line up, let me know, not a problem.
