RTI Test

Pugrocker stopped by my place today and I dragged out, with his help my 30* RTI ramp, was pretty fun to have someone measure for me as I measured for him.

Just went to a RTI calc to figure what we got.

Pug
Traveled 39" up, stock WB, with 3" nationals, SPUA, with revolvers scored a 30* 487 or 23* 623

Me
Traveled up 67", 82" WB, SPOA, YJ, and (my)drop shackle in rear, scored 30* 817 or 23* 1044

Thats pretty cool, always wanted to know how it did, but never tested it
though I really need an antiwrap bar for my rear

Re: RTI Test

Thats really not bad for spua I bet of you were spoa you would be real close to your buddy's score. Also did you guys follow all the rules, no weight shifting, tires aired up, shocks attached,did you go backwards or forwards?

Re: RTI Test

we did it street at air pressures (I am at 20 psi),forward, no weight shifting and with the shocks attached......my revolvers didn't really even open up too much which in my mind means that if I put on a longer shock, maybe I will get higher up the ramp......

Re: RTI Test

doug:

how did you calculate the scores - I went to www.sierrarockcrawlers.com/tech/rti.html and entered in a 30* ramp, 39" height and a 79.9" wheelbase and the calculator returned a score of 976???

Were we supposed to measure from the ground to the center of the wheel or from the bottom of the ramp to the center of the wheel?

Re: RTI Test

>>39" height <<

That was distance up the ramp, your height(from ground up vertical) I think was closer to 19.5

Different calc's use differnt measurements to make it up

Re: RTI Test

>>>The distance the vehicle can travel up the ramp without losing contact with the ground is measured from the leading edge of the ramp to the center of the hub on the ramp. That number is then divided by the vehicles wheelbase (the distance between the vehicles centerline of the front axle and the centerline of the rear axle) and then multiplied by 1000 to calculate the average. For instance, if a vehicle with a wheelbase of 94 inches travels 62 inches up the 20 degree ramp then the RTI would be calculated as: 62" divided by 94" x 1000 resulting in a score of 659<<<

I got that info from http://www.offroaders.com/info/tech-corner/rti.htm

They also have a good rti Calc, you enter your height, ramp and WB, and it'll tell you the distance you traveled up it, which makes it easier for double checking.

Re: RTI Test

Were your shocks maxed out pug? If they weren't then longer shocks won't help. Easiest way to tell is just to disconnect them. IMO I don't think a spua rig will ever out flex a spoa rig. I have a pretty good spua suspension with Missing Links all the way around and rears upfront and cj's in the rear. My rear flex's out OK but like you said with your revolvers my Mlinks barely opened up. On my rear shocks I had one that was bottomed out and the other was maxed out. On the front I still had several inches of availible travel with each shock and the Mlinks hadn't even started to expand yet. I fyou take the shocks off and find you have more room then make some upper shock mounts and buy some new shocks if you don't wanna spoa it.

Re: RTI Test

Hey cool, I was just thinking about asking what you guys had on the RTI since I just did it now that I'm SPOA with 31's...

Last year I was Bonestock, and If my memory serves me right, I had around 630. Now that I have SPOA and 31's with longuer extention shocks, I measured a Nice 839 on the 23 degree. I'm really happy with the results...but I was wondering if thats normal for a SPOA with 31's...?

Whats the average...Coomon guys, lets see those figures...[img]images/icons/wink.gif[/img]
