mike

 

wont let me upload for some reason i have other pics welds are flawless

 

**** man you want some gloves? I got plenty.

 

Hope you cert guy isn't by the book or you'll have some problems.

 

why ?

 

What the hell, why even make a post implying something is wrong if you aren't going to say what is actually wrong?

 

thank you essex , ive just confirmed with a racer in field that the sfwd class isnt looking for much ,for 8.5 cert ... somthing about there must be a X in the back bars where the rear seat belt brackets are and in the very back where the parachute mount is . ANY BODY WANNA CONFIRM THAT ????

 

what do your floor plates look like? and is the seat mounted yet? looks like its not, but if it is its too far from the main hoop

 

im kinda short i weight alittle over 115 lbs im running a twin disk and i like being cramped in the seat to the dash i did make the seat bracket already i was just going to install a brace to the center mainhoop bar to the back of the seat for extra support , is there a minimum distance from seat to main or helmet to main hoop ?? And the floor plates are 6"by6" quarter inch thick, im positive they will fly .

 

Damn 1/4 inch thick plate?! Really? You just need 1/8 inch. How is your down bar hooked to your A piller? And no you dont need an X bar in the back, but where ever your bars going down need to be attached to the a 6x6 plate. A problem you might have is your rocker bar. Some techs say it needs to be attached to a 6x6 and not the main hoop. Others have allowed it to main hoop, that might be your only issue. Pass that looks good for me.

Also might be the pic but is your main hoop plum? Kind of looks like its tilting to the back up top.

 

Get ahold of the guy that is going to cert you cage. From the first pic i can tell that the D bar isn't correct. The D bars need to run down to a bar that runs from door seal to door seal. and if the seat is already mounted, it looks to far from the main hoop. Maximum of 6" from roll bar to driver’s helmet (from nhra rule book). Not trying to discouraged you. just trying to help. it sucks when you get everything welded and think your finished. But then get failed and have to go and cut an fix it.

 

yea the main hooop tilts back a little bit not much its all tied in together, are u refering to the down bar as the door bar ? if so thats attached 2 inches from the bottom 6-6 of the A piller "which is where your feet would be". The "c bars" the ones where the back seats are from the main hoop go down and attach to another 6-6 plates as well yes .. what are u refering to as the rocker bar ??im kinda a noob to these terms

 

it is a 6" max from your helmet to the top of the main hoop. your gonna be about a foot when your sitting in the car.

 

yea that was somthinng i was a little concerded about but like i said im 5"2 i weight 115 lbs so i need to use the back of the seat to press against so i can push my clutch in ,"its a cc twin disk" its like a rock ..... Should i just tilt the seat back to get the clearence i need ? ru sure it wont fly ,i made it to be comfortable for me ?

 

you should have made the hoop closer



a tech might let it slide, but its not right

 

TinyT where did you get that? Are there more pages with info?

 

they are around on some different forums. your best bet is to just get an nhra rulebook, those are good up to 8.50's. when you get into sfi 25. series stuff (sub 8.50's) you have to buy the rule book from the sfi foundation

heres a link to some more info. the picture in this is wrong, that style cage is only good to 8.50's, it says 7.50's. 7.50's needs at least a 25.5

That hoop is way to far back from your helmet. YOu being small or not and needing to push off the seat, you should have the hoop closer then

A decent tech is going to catch this for sure, either move the seat or the bar and save yourself the fail

 

Do you mean a rollbar? where is the diagram for a rollcage? He has a cage The 6" rule I see in the rollbar diagram

 

I was told the 6" rule is the same for a cage or a roll bar but I will make a call tomorrow

 

cool Tiny^

maybe he can make some pedal extensions like this if its just a mater of moving the seat back...just an idea

 

Can i make a adjustable seat bracket ?? im diggin them peddle extensions , im not touchin my cage unless i have to.

 

Im getting some mixed answers on this issue, ill let you know when I get a definite answer. you could also get an nhra rulebook. I dont have one for some reason.
