nhra water relocation

[coldsmoke]

so right on the first paragraph of cooling in the nhra rules it says radiators must be in stock location of the vehicle .ive seen a few guys with radiators in the beds and wonder is there a new adendum that i missed or how do they get away with this? i want todo something similiar and just run a tranny cooler for the coolant in the bed or just a couple feet of hose going from upper to lower inlets with nothing inbetween since i dont ever get hot enough to justify having a radiator.basically just water in the block . will be filling it next year but until then wanting bare minimum approach for water in the block.

I'm curious about this as well.

There are many rules that seem to be overlooked on a regular basis. Aftermarket axles, fuel cells mounted below the top of the tires, coolant instead of water, etc.

That's a stupid rule. Where's the "stock location" on a car with a glass front and engine setback?? There's only about a billion out there. I've never seen that one enforced.

I have seen the "no coolant" one enforced.

[coldsmoke]

il just ask my local track and if they say no well i guess its just time for it to be filled.

Follow the rules or don't race. I can't stand guys who blindly build and then get upset cause they didn't look at the rule book.

It's good to know what the rules are not only will it keep you safe, but it could be the difference in a win or a loss, if protested.

what do u mean uve seen the no coolant one enforced? theres a new rule about filled blocks?

[unfinished business]

Where did that come from?! No need to be rude, the guy is asking the right questions.

How much is tolerated depends on the series you are racing in. If it's local NHRA bracket racing, then it's dependent on the track. If you are racing at NHRA Lucas oil divisional races then there is very little tolerance. Remember to, that it's not just the NHRA tech inspectors, it can also be other racers that file a complaint. And yes at divisional events I have been checked for antifreeze, engine diaper, after market axles, flex plate, etc.

How much diesel stuff is actually rated property ? Also at what speed/E.T do these rules start getting strict?

Properly rated stuff is available. Just costs money.

It not so much as what speed or E.T. , but what class. If you race at divisional or as John Robinson does at national events, there is very little tolerance.

The rules have reasons, some for safety, so for other reasons. I know the aftermarket axle rule doesn't seem to make much sense, but If you have ever had a axle come shooting across the track at you, it kinda changes your mind. That is why the full floating axle rule exists by the way. If the flange on the end of the axle breaks, there is nothing to keep the axle in the housing. It has nothing to do with loosing traction on one wheel.

I have no idea on the water relocation rule. You can email the division tech inspector though. If you explain the question, and back up your stance with fact, they can/will bring it up to the NHRA rules committee.

i just see other peoples trucks doin stuff that is clearly stated not todo. not a grayish area but black and white clear as day. not ragging on the guys just curious how they get away with it . like the techs dont give a crap or iam missing something or a new set of rules

[bgreen776]

Racing was essentially founded by people breaking the "rules". Some choose not to, others... not so much.

Seems to be track to track. There are many tracks that don't care as well as some organizations.

Our local track is strict, even racing most every week here, and having the same tech person, they still look closely at the cars/trucks. As Paul pointed out at divisionals and nationals there are most always NHRA techs present and they usually don't cut anyone any slack.

I've not seen the radiator in the front rule enforced, that is a strange rule IMO. I'd speak with your local track tech or like Paul mentioned calling the divisional tech. I had a rules discussion that went up through the NHRA tech chain on the axle rule for our trucks and received an exception so it's worth a call.

Not following the aftermarket axle rule. Tons and tons of cars run built 9" rear ends with aftermarket axles (mosier ect). How are they racing?

[jasonc]

Aftermarket axles are required.

[bgreen776]

Aftermarket axle shafts are required per NHRA and IHRA rule books. I can't speak to the other organizations, but I do know that this is a rule that is very often overlooked, and because of that it deserves a second look by the rules committees to see if there should be a written exception. Requiring a 13 second 1 ton 4x4 to buy a full set of axles is the definition of ridiculous. Any authority overlooking certain rules invalidates all their rules and creates liability for themselves and the entity the rules were written for.
