kc8oye Posted October 18, 2009 Share Posted October 18, 2009 I've read over the NHRA rules before.. I would definately get that cage inspected by an NHRA tech because I dont' think removeable bars are legal at all in cases where the cage is required... obviously if you have a cage like that in say.. a 12 second car. nobody will care.. but if you were running 10.0's it would become an issue. still, it's a nice cage for a fast street car!

TommyP Posted October 19, 2009 Share Posted October 19, 2009 I'm pretty sure that the swing out side bars are legal down to probably at least 10.00 anything in the 9's requires a whole lot more safety stuff. I think that the only thing that might be a issue is the removable rear bar. I hope that it's legal because I really like the idea. Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted October 19, 2009 Author Share Posted October 19, 2009 well I don't know guys, this seems to be of great controversy but I don't think I'm taking it out just now. What I know is this, Chris Alston Chassisworks has been buiding rollbars for 35 years. I guess I'm way to trusting and I'll get proven wrong but they state their rollbar, swing-outs and removable back bar are NHRA legal. I'll call them tomorrow and go over it with them and see what they say. The rollbar is supposed to be good to 10 flat, anything faster you get into cage county. A "cage" has a halo with bars at the "A" pillars (minimum), totally different from a rollbar. I ran at Fontana to today, a pretty well know track, at a SCEDA/Super Stock Assoc meet. When I went through tech he inspected my harness for expiration and didn't say a word regarding the rollbar. You know what he dinged me for??? I didn't have metal valve stems in the front wheels!! He said he would give me a break (oh thank you Mr. techman) and let me run this time. The bad news, I only got to make one run as I think I lost a head gasket. The good news, my new ProSystems carb seemed to work pretty good. My best 60' dropped from 1.70 to 1.59...my best 1/8 et dropped from 7.48 to 7.19 @ 95 mph....and my best 1/4 dropped from 11.69 to 11.33 @ 118 mph...good thing I got the bar..hope it's legal...woo hoo........

CrazyDavey Posted October 19, 2009 Author Share Posted October 19, 2009 Great Times Dave, I hope it is not a head gasket. thanks Mike, I kinda hope it is because the alternatives are expensive... Quote Link to comment Share on other sites More sharing options...
dbreese Posted October 19, 2009 Share Posted October 19, 2009 Great times Dave. 60's are rockin!!! Patrick really knows his stuff!!! David Quote Link to comment Share on other sites More sharing options...
502ci Posted October 19, 2009 Share Posted October 19, 2009 Wow, huge improvement in your times... As far as the roll bar the only thing I questioned was the bar behind the seat and how the door bar clevis was welded on, those swing out door bars are definatley legal and they are legal down to I think 7.50 seconds but don't quote me on that...

Jared Richey Posted October 19, 2009 Share Posted October 19, 2009 I guess I better get snappy. I'd say the carb worked well also. Oh and $800 to remove that whole interior and put it back, now I see why it was $800. They done a great job! Quote Link to comment Share on other sites More sharing options...

I just did some checking and I was correct...a swing out door is NHRA acceptable down to 7.50...although on a bad note in the same article they stated the cross brace must be welded to the main hoop when running 11.49 and faster...

kc8oye Posted October 19, 2009 Share Posted October 19, 2009 my guess is that removeable roll bar is for the people who want the looks of a 'roll cage' in their street machine Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted October 19, 2009 Author Share Posted October 19, 2009 my guess is that removeable roll bar is for the people who want the looks of a 'roll cage' in their street machine Tim, the rollbar isn't removable, just the back brace. This rollbar is good to 10 flat...you only need a cage below that Quote Link to comment Share on other sites More sharing options...
kc8oye Posted October 19, 2009 Share Posted October 19, 2009 yeah taht's what I meant.. your rear brace. Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted October 19, 2009 Author Share Posted October 19, 2009 yeah taht's what I meant.. your rear brace. okay Tim, yeah I'm going to check with the company who made it. I'll post what I find out... Quote Link to comment Share on other sites More sharing options...
kc8oye Posted October 19, 2009 Share Posted October 19, 2009 From my 2008 NHRA rule book (I'm gonna order a 2010 book as soon as they are available) section 4.10 "Roll Bar" page 77 Quote: Crossbar and rear braces must be welded to main hoop... Swing out side bar permitted... that's all that was there that pertains to this topic :> Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted October 19, 2009 Author Share Posted October 19, 2009 I could be wrong but I thought I saw something the said the 2010 book was going to be on-line now and available about Nov 1...... Quote Link to comment Share on other sites More sharing options...
502ci Posted October 19, 2009 Share Posted October 19, 2009 interesting....you don't need anything down to 11.49 It was worded that way in the article, not sure why though other than than the fact it was talking about convertibles also in the article which needed a roll bar sooner...which come to think of it I think has been changed...maybe I was reading outdated rules...
