Superdasher Posted June 11, 2006 Share Posted June 11, 2006 This is an interesting fact about that Vekoma Boomerang clone found at just about every park in the US. I consulted RCDB, and found this out: A standard Vekoma Boomerang pulls 5.2Gs, while an Invertigo pulls 5 exactly, and a Deja Vu pulls 4.5. Cool, huh? Note though, that I am unsure as to which row this value was recorded in. My best guess is that it hits 5.2Gs in either the front row during the Cobra Roll going forwards, or in the back row during the Vertical Loop going backwards. I've ridden a Boomerang in both of these locations, but I never would've taken any notice of this if it hadn't been for RCDB. I guess I'm pretty insensitve to positive Gs - with the exception of powered launches and the Pretzel Loop on SUF, I don't find positive Gs as noticeable as negative Gs (aka airtime). But it's still a cool fact! Link to comment Share on other sites More sharing options...
SLUSHIE Posted June 11, 2006 Share Posted June 11, 2006 I've always thought the loop going backwards was pretty powerfull. Weird how every new design (Boomerang, Invertigo, Deja Vu) got weaker. Link to comment Share on other sites More sharing options...
okinawaboy11 Posted June 11, 2006 Share Posted June 11, 2006 ^ I noticed that when I rode 2Face. The return run was incredibly... G-Full. I acually greyed out for a tad sec. Link to comment Share on other sites More sharing options...
coasterfreak101 Posted June 11, 2006 Share Posted June 11, 2006 Yeah, on SFA's Two Face, if you sit all the way in the very back seat (taking the 1st trip backwards), the return trip (forwards) is amazingly powerful, especially through the entire vertical loop. It feels more powerful than HP's Sidewinder (boomerang) personally. --Tyler Link to comment Share on other sites More sharing options...
xsk8erboi73x Posted June 11, 2006 Share Posted June 11, 2006 sure doesnt feel like it... deja vu i blacked out for about almost a second... and boomerang i didnt.. Link to comment Share on other sites More sharing options...
okinawaboy11 Posted June 11, 2006 Share Posted June 11, 2006 I found DeJa Vu, surprisingly, Forceless. And rough. :-\ Link to comment Share on other sites More sharing options...
martinb Posted June 11, 2006 Share Posted June 11, 2006 but I never would've taken any notice of this if it hadn't been for RCDB. Same here, but the srtange this is, I heard on a program about coasters that if it goes over 5g's your eyes will bulge and you#ll get nose bleeds, I'm not lieing, it was serious program, more about g-froces really than roller coasters. -Martyn Link to comment Share on other sites More sharing options...

mike541x Posted June 11, 2006 Share Posted June 11, 2006 When I went on Twoface and went on the loop backwards it gave alot of Gs and very intense and powerful. Link to comment Share on other sites More sharing options...
steel Posted June 11, 2006 Share Posted June 11, 2006 The area between the loop and the cobra roll going backwards is especially powerful in the positives category on standard Vekoma Boomerangs. Haven't been on an Invertigo (next summer). I would say that the are between the second spike and the loop going backwards is the biggie on the Deja Vu model, but that's more of a weird "catch" than anything. Can't figure this one out.

redunzelizer Posted June 11, 2006 Share Posted June 11, 2006 Same here, but the srtange this is, I heard on a program about coasters that if it goes over 5g's your eyes will bulge and you#ll get nose bleeds, I'm not lieing, it was serious program, more about g-froces really than roller coasters. That program might well have been very correct. But: any "damage" g-forces could do to your health is very dependent on the duration of impact. For instance, rapidly sitting down on an "unpillowed" chair could easily give you 11g (eleven!) in your butt. Got hurt? No. And like jumping down from a wall about 1m (~3ft) high might pull up to 20-25gs in your ankles. Same with advanced skiing and lots of other sports... On rollercoasters, said "really really high g-forces" (4.5 - 6.5g) do occur for fractions of a second only, and "quite high g-forces" (3 - 4g) for just a few seconds, so besides the risk of greying/blacking out (which is a "harmless" warning signal, but not any actual threat yet), there are more than enough safety margins. Do not classify any g-forces unless you consider duration, as well as point and orientation of impact also. And now stomp on your accelerometer... 8) Link to comment Share on other sites More sharing options...
Twister II Posted June 11, 2006 Share Posted June 11, 2006 I don't believe it. Millennium Force pulls like 5.5G's at the bottom of the first hill. Link to comment Share on other sites More sharing options...
Darien Laker Posted June 12, 2006 Share Posted June 12, 2006 I think Millennium Force only has 4.5. I've always found Boomerangs to be intense, and if you're lucky enough to have a smooth one, they're actually decent rides. SFDL's is the park's smoothest coaster (MAYBE tied with S:ROS, but that's getting an unforseen "Intamin Rattle" to it). I always grey out in the loop going backwards. Really, Just because a ride has been cloned 40+ times doesn't mean it has to be terrible. Link to comment Share on other sites More sharing options...
Cerberus Posted June 12, 2006 Share Posted June 12, 2006 Just because a ride has been cloned 40+ times doesn't mean it has to be terrible. Yeah. And actually, I'd say a ride that has been cloned 40+ times is pretty dam awesome at doing what it does! Sales figures speak louder than enthusiast opinions As for pulling massive Gs, I'm not surprised at all. It has to complete three loops of the same size off one drop. It's hitting those first loops pretty hard if it wants to make through the rest! Link to comment Share on other sites More sharing options...
Blue0ctane Posted June 12, 2006 Share Posted June 12, 2006 Millennium Force does pull a load of G's when it levels out. Maybe it was just the shakiness of moving at 93 miles per hour, but I could've sworn that my eyelids were being pulled down due to the G-forces. I've never been on a Boomerang, but I'd guess that the most intense G-forces would be on the cobra roll. On my first Hulk ride I grayed out on the cobra roll, and my friend Ezra did on his first Hulk ride also. Link to comment Share on other sites More sharing options...
TheStig Posted June 12, 2006 Share Posted June 12, 2006 You know, untill I rode my second boomerang last week I didnt remember how good they can be! I've ridden the GL and WA boomerangs, both pretty smooth, but I guess I forgot how intence they can be! I did notice that the return trip through the loop in the front of the train is the most intence spot. Its funny, because as you enter the loop its kinda weak, but once the rest of the train starts picking up speed again, the pull out is intence (that last part sounded really wrong!). But yeah, the cobra roll is pretty good in the front car too, but not nearly as intence because the loop is a good 5 feet shorter than the cobra roll.

QueerRudie Posted June 12, 2006 Share Posted June 12, 2006 I will say this about the vast majority of Vekoma coasters- OUCH. But that's a segment of them- A few have been downright smooth, with very few bits of turbulence (I.E> SFA's TwoFace)- and last week I was on SideWinder at HersheyPark- it was just about the roughest I have ever remembered it. I've have yet to find a Inverted class (I.E. Mindbender at SFA, Kong at SFMW) that was smooth- but SFA's is a bit tolerable in the front seat. Having ridden both types of Flying Dutchman, I can say this- not bad at all. In fact, they were as smooth as any early Arrow- Link to comment Share on other sites More sharing options...
Superdasher Posted October 27, 2006 Author Share Posted October 27, 2006 With the help of NoLimits, I can now confirm that on a standard Boomerang, the 5.2Gs is hit in the back row in the vertical loop backwards, right as you are fully upside down. Sure enough, I rode a Boomerang in real life not too long ago in the very back row, and this time I could definitely feel the Gs going through the loop backwards... Unfortunately though, the back row is also where the roughest ride is! Link to comment Share on other sites More sharing options...
CP_RULES Posted October 27, 2006 Share Posted October 27, 2006 To be quite honest, Ive never really noticed the positive Gs on Boomerangs. I dont know if its the length of "impact", or the fact that your sitting down, but B:TR's 4g's seems a hell of a lot more forceful than any sit-down's 5.2. I guess inverts are just a lot easier to tell positives, because I cant really think of a sit-down Ive been on that I remember having tremendously great positives, including MF.

But what I do know, is that there is a trim at the bottom of the loop. You can see here: http://www.rcdb.com/ig283.htm?picture=1 Link to comment Share on other sites More sharing options...

Loco Posted October 28, 2006 Share Posted October 28, 2006 IMO I love boomerangs! I can ride them all day if i wanted to. (id get extremely bored though) and they're really smartly designed aswell. Link to comment Share on other sites More sharing options...
Ccron10 Posted October 28, 2006 Share Posted October 28, 2006 I thought I heard from somewhere that Riddler's Revenge has the most G's. I never heard anything about Boomerangs doing that. Link to comment Share on other sites More sharing options...
larrygator Posted October 28, 2006 Share Posted October 28, 2006 I would have to say that anyone who has ever ridden a Vekoma Boomerang and didn't notice the high G's on the backwards loop is a little clueless. OK a lot clueless! Link to comment Share on other sites More sharing options...
BDG Posted October 28, 2006 Share Posted October 28, 2006 It's not the actual force that matters, but the duration. I can guarantee you that 3 seconds of 3G in a helix will feel alot worse than 0.2 seconds of 5G at the bottom of a drop. Link to comment Share on other sites More sharing options...
