Rocket- FVDed

^I think PTC's could hit that mark for an initial or ending value b ut never sustain that kind of force. Infact, I think Ive felt some jolts from crappy leadins that probably throw the meter up there.

The difference between an Intamin Woodie and Regular Woodie is more about how the G Forces are applied not just the G Forces themselves. Being mostly a ride designed after a steel, Intamin Woodies can sustain those G's alot longer because the trains are, Im sure, just regular mega trains retrofitted with different lapbars and a different wheel assembly.

I wouldnt say hitting those marks is out of the question either on PTC's.


Also Jake, I think what you felt on SROS differs a TON from Xcel. Sustained G's will always feel more intense than G's that last a fraction as long.

Well, if I use 85 mph, it gets to -1.7, so 84 is fine, and it rides almost exactly the same.

Edit: It sustains about 4 seconds between -0.6 and -1.3 gs, so that's pretty intense.

You are building with the FVD formulas and then changing the speed after its built?

Only by a half a mph, and, with the lower speed, the g-forces are exactly what I wanted them to be (the ones in the Elementary). God, I have to say this 10 times? Sheesh...

And exactly where did you hear this?

On the old coasters2k site, a thread was posted by a very trusted member (jonbkchill I'm pretty sure) which gave the official g-limits allowed for wood and steel coasters, and how long they could be sustained for. I forgot what the name of the source was, it was an organization that set guidelines for amusement park attractions (anyone who was a member there a few years ago and saw this, can you refresh my memory a little? TConwell is the only active member here that I'm pretty sure saw it). But anyways, he became a member to the organization and had access to official g-force guidelines. One of them stated that the maximum g-forces allowed for PTC trains was either -1.2g or -1.3g, can't remember exactly which.

Intaminfan, SROS and El Toro both pull about -1.3 and that is a TON of force.

Source?

^Not sure about El Toro, but here is Superman;

^The spot at 80 seconds is right where the ride pulls about -1.3...that chart was made from testruns with no passengers and in the winter FYI.

Real, I agree, fast sudden jolts of -1.3 may be acceptable, but any sustained force like on SROS would just be killer with PTC's IMO. You're right about Xcel though, it and SROS provide different styles of air. It's just the fact that SROS sustains it that makes it feel alot stronger.

And, where do you know is that tested from? Is it an average of the front and back or something?

If SROS sustains -1.3g, what makes you think that Intamins can't go higher than -1.3g if the force ISN'T sustained?

Also, has anyone here ridden SROS @ Darien Lake and/or SFA, and SROS @ SFNE? If so, how does the hill after the straightaway on the DL/SFA versions compare negative g wise to SFNE's?

Also, no biased responses please. I know that SFNE's SROS has more negative gs all around, by a large margin. I'm comparing SFNE's SROS to the hill after the straightaway ONLY.

I have ridden the SFA version...I would guess the hill you speak of is about the equivalent to SROS SFNE's first hill, around -0.8. However, I will be able to make a more accurate next summer when I ride both coasters (within a week of eachother).

Wow...way off-topic and very controversial. So, is -0.6 to -1.3 for 4 seconds fine (at max- tested in every seat)?

Your tophat is horribly wrong shaping wise. Smooth or not, it's wrong as hell.

Well I wanted the forces to remain as constant as possible in all of the seats.

Pretty ugly tophat

I know.

If you know, then why haven't you changed it.

^as long as it's smooth, he doesn't care.

Wait you know that you can have a pretty, smooth, and exhilerating tophat all at once, right, EELover?

Yes, that's fine. However, you can't have very high sustained positive Gs right after that.

^ Well, it pulls about 4.1-4.2 for about 3-4 seconds.
