Johnny,  first off WELCOME...

Now let me help clarify a few things... Safety Requirements and Car Classifications do not always go hand in hand.

As someone new to LSR
The most important thing is that the car and driver have the proper safety gear for the intended max speed you think you can run. (as you may run in TO or Time Only class if your not after a class record) in running Time Only,, the car and driver will be "tech'd"  to a max speed based upon the installed safety equipment in the car and the drivers personal safety gear)

Now for a few starting specifics... do you feel your car can go over 135 MPH in a standing start 1.5 mile course ?  If so after 135 you enter RACE CAR STUFF  LOL....

135 and below... no roll bar, but you must have at least 3 point seat belts, SFI 2005 or 2010 Helmet, Long Pants and Long Sleeve Shirt,,Gloves, closed toe shoes. a safe car and good tires with proper air pressure.

After 135 you then get into Roll Bars, Racing Seats, Racing 5 point or better seat belts, better speed rated tires etc... after 150 more roll bar, better tires a fire system etc.. after 175 add a parachute a full cage, better tires, a second fire bottle, fresh air intake for the drivers area,, etc... as you can see it's easy..

***my comments are not intended to replace reading the rule book 10 times over cover to cover,, which you should do..just a quick overview...
Welcome and bring that Buick up and have some fun...

i know changing drag car to lsr car will require me add parts and weight back to the car. i am only going to the 149 mark as beyond that the pocketbook wont stretch anymore(yes dear, just another dollar  ).
i have read the book a couple of times. as i said in the thread start, those areas are a little confusing. what do i have to do to be legal and safe?

4 point roll bar, fire suit, shoes, gloves, helmet, 5 point seat belt above 150 you need additional equipment like fire protection, race seat, 6 point roll bar. Read your rule book again!

[Cajun Kid]

Stay 150 and below and you can be legal with just a 4 point roll bar and basic drivers gear.  No Chute and  No Fire system required.

Been on 2 wheels a little while now but i thought you were also required to have a drive shaft loop and 2 throttle return springs once you crossed the 135 line.  Also pay attention to tire ratings...

I am a Bonneville racer and a tech inspector.... I do not know the exact rules for your venue but it seems like a few of the people who have posted replies do know.... If you are unsure, ask more questions..... there is no such thing as a dumb question in my books!.... asking what some would call dumb questions usually prevents the making of dumb mistakes!

Milt, I do think you are correct,,, my replies have been to address the Items that require FAB time, more time and money etc. for his stage of build,,, Like Chutes, Roll Bars, Seats and Belts and Fire Systems.

Throttle springs, shaft loop etc.. "should be common knowledge" and are easy and inexpensive add on's..

But yes,, you are right and I guess when asked an open ended question we should be more elaborate with our answers,, ..


Hope your DUC  is coming along well.

See you in April

i have the 2010 ecta book which i assume would be for loring also. correct me if i'm wrong.
but anyways, the rollbar section mentions classes and diameters. thats why i asked about car class. if somebody does time only, what diameter do you use??? very confusing. besides, i don't like to read between the lines when it comes to safety.
i am going with minimum of 6 point. and are swing out bars legal? and staying under 150 i still can have the oem bench seat??

thanks

  Minimum pipe diameter for your engine size is 1 5/8 inches. Swing-out door bars should be fine.

[gsjohnny]

safety film, what brand are we supposed to use on the windows?

thanks for all the help.

[tedgram]

Not needed if you have safety glass.

[Cajun Kid]

For  150 to 175  you can use  1 5/8 x.120 roll bar tubing  I would use DOM,,, and if you ever think you may want to go faster you may want to use 1 3/4 x .120 DOM,,, and yes swing out bars are OK,,,, Competition Engineering/Moroso makes a swing out kit as does Art Morrison and several other companies.

As to a bench seat,,, I am not sure,,, but I am not going to use a bench seat over 135... so ask Joe Timney from Delaware Chassis Works,,, he can help with the seat question.

No safety film needed for your speeds.. also factory glass is safety glass (laminated) so it is OK.

Keep us posted,,

Some factory glass is tempered.

got a neighbor down the street that does nascar modifieds. he will do the roll bar for a good price. if i keep giving him turnips and other stuff, it will cost me nothing. .
i think the 73 glass is laminated. i have some spares i could test. anybody know what brand and kind of safety film?

thanks
