Rubbels 426 Stroker Engine Pics

I chose the 2.98 set-up with a 3.55 rear end. That would be around 6600 RPM @ 153 MPH in the quarter if I'm running in the 9's. The engine built by Power Ported Performance should be good up to 8000 RPM but obviously shift points will be based on HP/TQ curves. Running 28" dia. full slicks.

Where is the chute if your trap speeds exceed 150 mph?

[justinSRT8]

can i buy your axels?

maybe the differental too. i'll have to get on how much dodge wants for the ring and pinion first on that one tho.

[rubbel]

Honestly I do not know if a chute is required over 150 but if necessary I'd use Stroud Safety for one. In my drag classes I learned chutes really are not very effective until you run over 200 MPH at the track.

[Abnmarine]

I'm sure you are aware of these but they will need to be addressed if running the predicted times.


2.3 REAREND

After market axles and axle-retention device mandatory on any car running 10.99 (*6.99) or quicker and any car with locked differential. Cars running 10.99 (*6.99) or quicker that weigh more than 2,000 pounds (907 kg) with independent rear suspension must have swing axle differential replaced with conventional differential housing assembly.

4.4 PARACHUTE

Mandatory on any car with top speed in excess of 150 mph (241.4 km/h). See General Regulations 4.8.

6.4 WINDOW NET

Mandatory in any full bodied car required by the rules to have a roll cage. See General Regulations 6.3, 10.3.

8.3 MASTER CUTOFF

Mandatory on any car with a battery running 9.99 (*6.39) or quicker, or any car exceeding 135 mph (217.2 km/h) or on any car where the battery is relocated into the trunk area. See General Regulations 8.4.

4.8 PARACHUTES

If outlined in Class Requirements, mandatory to have a braking parachute produced by a recognized drag racing parachute manufacturer. Scrutineers may observe the proper operation of the parachute and inspect for worn or frayed shroud lines, ripped or dirty canopies and worn or ragged pilot chutes. Parachute cable housings should be mounted solidly to frame tube or other suitable member no further back than 1-inch (2.5 cm). The release housing must be attached within 12-inches (30.5 cm) of the parachute pack and in a manner that will allow the inner cable to release the chute. When supercharged and/or using nitromethane as a fuel, it is mandatory that the parachute pack and unpacked shroud lines be protected with fire-resistant material from the mounting point into the pack. Parachutes must have their own independent mounting. The use of ball-lock pins for parachute mounting prohibited. See Class Requirements regarding use of two parachutes. Such applications require separate shroud-line mounting points for each parachute system.

6.3 WINDOW NET

A ribbon type or SFI spec 27.1 mesh type window net is mandatory on any full-bodied car required by the rules to have a roll cage. Window net must be securely mounted on the inside of the roll cage, with the permanent attachment at the bottom. All attachment points must be designed in an attempt to protect the driver and avoid contact with track surface or guardwall. Eyelet clips, dogleash hardware, hose clamps, etc. prohibited. Penetration of webbing, except as performed by manufacturer, prohibited. Any modification to net must be performed by manufacturer.

8.4 MASTER CUTOFF

Mandatory when battery is relocated, or as outlined in Class Requirements. An electrical power cutoff switch (one only) must be installed on the rearmost part of each vehicle and be easily accessible from outside the car body. This cutoff switch must be connected to the positive side of the electrical system and must stop all electrical functions including magneto ignition. The external control switch for this cutoff switch will be clearly indicated by a red flash inside a white-edged blue triangle with a base of at least 12 cm (see drawing 25). The positions must be clearly indicated with the word "OFF". If switch is "push/pull" type, push must be the action for shutting off the electrical system, pull to turn it on. Any rods or cables used to activate the switch must be minimum 1/8-inch (3.2 mm) diameter. Plastic or keyed switches prohibited. Switches and/or controls must be located behind rear wheels on rear engine dragsters.

I for one hope that "little problem" needs to be addressed

[rubbel]

Master cutoff done The Big Switch

Fire suppression done

Rear end should be covered

Window net in discussion and no big problem to do.

Parachute still open to do

Sub 10 sec. pass still open to do!!!

I am a firm believer in safety equipment and that issue has not been ignored. But with so many details still being finished some things are still unanswered.

An example - At 7:30 PM today we decided to mount our gauges on the front roll bar in a row.
What gauge where, ect

There are some fast cars out there striving to get into the nines running the track without a lot of the required safety equipment. No bluejeans here. A full SFI Simpson suit, sfi neck brace, sfi gloves, sfi shoes, ect. already done.

We are finding answers each day but not everything has been resolved at this point.

No I understand completely. A build like this takes a lot of time and thought to build it correctly. If it was me, I'd make some runs to see where you are at prior to adding the chute. I'm thinking you will need it but it wouldn't hurt to do some shakedown runs first to see where you are at. I'm enjoying watching your car progress.

From day one priorities were

1) Excellent Quality in each thing we do

2) Safety is a priority over speed or looks

3) FUN - if we do not have fun something is wrong as this is a hobby

4) Performance - I'm competitive by nature and want to win

5) When we are done everyone involved is proud of their accomplishments and contributions to this major project.

I expect several 200 foot passes, then some 600 foot passes, and some 1/8 mile before ever running the 1/4. But from day one I plan on using slicks and full throttle and making as hard a launch as possible to get that 60' time.

I went to drag classes at Gainesville here in FL and my 60' times were 1.54;1.45;1.291;1.290; and 1.187 so I know what a hard launch is.

My best 1/8 in six passes was 5.795 @ 118.17 mph

Letting off the gas at the 1/8 mile I ran 9.957 @ 73 mph in the 1/4 so I still have a lot to learn, but I will proceed safely and in steps.

forgot to mentions it was an 1/8 mile track
