Wow, yes I don't want that!!
scary!
Hell, do a drop in forged piston/rod combo, and blueprint the hell out of a Hellcrate/Hellcat/Redeye engine. They already have a top speed of 200. A little coaxing could easily get more.

Gosh you drag race characters have a lot to learn. SCTA/BNI have their own classes to run in; Streamliner, Lakester, Competition coupe, vintage streetrod and the list goes on and includes motorcycles and diesel trucks. Then engine displacement classification, then naturally aspirated or blown and then fuel being gasoline or fuel. Fuel could mean an alcohol, nitro or diesel.
You need to remember that a few short weeks before speed week the salt is probably under water and may still be damp. In 1998 the temperature was 105°F and the altitude is fairly high.
Yes weight is for stability but also traction with narrow tires for low resistance.
Friends from Calgary ran with number 1149 whoch was as close as they could get to N49 for North of 49. They could not crack 200MPH until someone told then to add weight for traction. They bolted 1" plate to the bottom of the chassis and finally went over 200MPH.
Licensing runs are on the short track of 2 miles with another mile to slow and stop. Once you have made progressive safe passes at increasing speeds but not exceeding 170MPH you are granted a license and can go to the long track for higher speed runs.
The best bet once you pick a class to compete in, you need to build a safety cage to specifications for that class, and then get ahold of SCTA/BNI for their tech inspectors to look it over with a core engine and MT trans case. Once your chassis is approved you can get serious about the engine build. Be forewarned you will likely be making a number of trips for inspection before even considering an entry to run. I would also seriously consider planning to attend Speed Week at least once and possibly with your car on a trailer just to talk to other competitors. These guys and gals are generally the uppity types common in
other organized motorsports. The worst nose in the air snobs are probably the F1 crowd. The land speed crowd is pretty laid back. The Bean Bandits are a great bunch to get to know.
No racing is cheap and land speed is no exception.

This is what I have learned since wanting to go down this road. Thank you for the summary for anyone reading this. I plan to be there next year to see it all in person and talk to as many people as I can.

On ashphalt and on the salt are two completely different kettles of fish. HP is required but weight and aerodynamics are big players. Weight goes against you in most racing events while the more the better on the salt, to a point. At approaching 200MPH air becomes like a brick wall and the salt is slippery, so traction is limited. If I was going to run I would look at building front wheel drive and front engine and run in a lakester or liner class. If you lose traction you can spin out which could lead to a ddangerous crash. If you lose traction on FWD with limited slip you just quit accelerating, but stay straight.

The pits area is pretty relaxed and you can generally find someone that will talk to you about their car and class. In 1998 there was a team running a 1941 International truck with a 16V 92 on the frame behind the cab. Essentially the back of the cab was the radiator with a duct through the cab taking cool air to the radiator. He got into the throttle a bit hard at 150MPH and spun out. Belt drive gave it pretty much direct drive in top gear.
Look for the Bean Bandits and try to get invited for their burrito supper. If you take the fixings to make Margaritas, they will likely make a blender full. Great guys with awesome stories. Ask them about the stollen car.

If I remember they require a catch pan in case an engine grenades. The salt is a National Heritage site and enviornmentally protected. In the pits a plastic catch sheet is required under the car when work is done to it, to keep oil out of the salt.
Sounds like you've "been there, done that". OP asked about making power. I don't pretend to know anything at all about salt racing. But, thanks for the education that I didn't ask for.

As an aside my buddy who is a tuner and runs a tuners podcast went to the salt and helped a team set a record with a blind driver. You can’t make this up. He had some just hilarious stories but they did it. The blind pilot of the car is also a machinist. His name escapes me now but neat guy. I thought sure he was reeling me in like a fish when he first started talking about.

I was talking building not buying used. And that’s not a Mopat.

Went to Bonneville for the 50th anniversary with a friend that had worked for Crondek that made the timing equipement. He had to stay for the week in case something happened that he had to repair. With time on his hands he got into announcing. This was 25 or so years previous. So I got some inside stories.
Then friends in Calgary built a car running BBC power and I got to hear their trials and tribulations stories. Their car is/was number 1149 for North of 49.

Single pot brakes is not really a big problem on the salt. 2 mile runout and parachutes allow time and distance to slow and stop. Remember that the air drag at speed will do a lot to slow the car just by getting out of the throttle and cutting fuel.
Liners and lakesters have very low CD so rely more on fuel cutoff and then the parachute. If you had road race or NASCAR brakes the low traction would allow the wheels to lock up.
Fuel and blown alcohol dragsters and funny cars do not have much for brakes, relying on their parachutes. They could install powerful brakes but that would add weight they do not want.
I hadn't even thought much about that, thank you!

Well $50k is a steal of a deal. To run 277MPH would likely take most of the $50k just for the engine. In a Camaro you have a fair bit of drag even with aero mods. Then you have the chassis and class compliant cage.

Way more power. The Daytonas and then the Superbirds were a bit faster due to the aerodynamics. The high wing helped downforce but the sails on the sides tended to aid keeping the rear from getting loose. Those Mopars dominated until NASCAR banned the winged wonders. That is when Ford introduced the more conventional aero package Talledegas.

People have scrutinized the rule book looking for a bit of a loophole or place they could gain an advantage. They may be a record holder in a class but change their engine to one that is only a couple of CID under the limit for a class where they think they could get that advantage. Their chassis is already sorted but may take a couple of years on engine developement.

That would put you in A or BBF and then the body class. Maybe a Neon engine could have an advantage in another class.
A or B is engine displacement.
Second B is blown.
F is fuel as not gasoline. Gasoline would be G.

First you need a class compliant cage for the weight and estimated/established speeds in the class. Better pick a class up front. Yu can take a car to the tech inspectors way in advance and have them inspect it. Better to have them tell you about required changes 6 months or a year in advance. They can also give guidance on choosing a class.

I forget the boost Speed Demon chewed to develop 2500HP.
To revive this thread....
What cam characteristics would you look for to go WOT for let's say 5miles. Something like the old purple 590??
