For those of you who run tracks that allow you to use the Borla header with either the Borla muffler or the open collector, always run the open Borla collector if possible. You will definitely make more horsepower and torque with this setup. However, if you have been running with the muffler and go to the open collector, you will need to go up one main jet size to realize your maximum power with the collector installed.

    For those of you that run smaller short tracks with slow, tight corners,  you will see some benefits by going to a header available from 600 Racing. This header will pick up the bottom end tremendously. We were pretty surprised at the difference this header made in the mid range. We saw a gain of 6 horse power and 6 foot pounds of torque at 6500 rpms with this header , all sold by 600 Racing . The header is a silver painted  mild steel header with a open collector that is held on by 4 springs known as the FJ header.

    Teams who run different type tracks  could really benefit by keeping both exhaust setups in the trailer so that you can put the best combination on your car for the type track you are on. This header is now not sold by 600Racing. You will have to find a used one.

   As always, if you have any questions about this header information or anything else, please give us a call at 706-367-1524 or shoot Ray an email directly at ray@redlinepro.com

To Shave Or Not To Shave?

    Changes in rules for Legends Cars allow teams to shave tires. There is no question about it. SHAVE YOUR TIRES!!! Shaving the tires accomplishes a number of different things for you. Primarily, it allows you to shave camber directly into the tread of the tire. Each corner of the car should have the camber shaved appropriately for it's location on the car. Our testing has shown considerable improvements in lap times by doing this. Shaving also can allow you to get the exact stagger that you are looking for. The shaved tread is also thinner, which gives the car a noticeably less squirmy feel and reduces tread "chunking", where large chunks of tread break off. With these improvements, a properly set up chassis can benefit with   more even tire wear after shaving. Tire shaving can also be a money saver for the cost conscious team. Old, hard tires can be "revitalized" by shaving them. The outer, harder rubber is removed which exposes the fresher, more pliant rubber underneath. The tires won't perform like a new set, but they make great practice tires and spares. This tire advise applies to Dwarf Cars, too!

     Keep in mind that the first few laps after shaving the tires will be a little slippery, new or used, so make sure to scrub them in good before running a race on them.

     Believe us, your driver will thank you for the more responsive and stable feel that the car will have and the drop in lap times will put a smile on everyone's face. We definitely recommend that you find a qualified person to give your tires a properly cambered shave.

(You can have the sideburns done however you want. Ha Ha!)

Fuel For Legends Cars   As of 2005 fuel not legal!

Here at Redline we try to test everything we can to make sure we are getting the best performance out of the Legends/Dwarf Car engines. We have tested most racing fuels that are available .  We have realized significant gains when mixing the racing fuels we have tested with 93 octane pump gas. The burn rate of straight racing fuel is too slow. Mixing with 93 octane pump gas speeds up the burn rate and picks up the horsepower and torque all the way up the power band. Usually a 50/50 mix is a good starting point. The best fuel we have tested is a new fuel call Ultimate 4 racing Fuel from VP.This fuel has out powered any fuel we have tested. RUN THIS FUEL STRAIGHT OUT OF THE CAN!

Air filters for Legends Cars:

We have found that the K&N dual air filters are far superior to any other filters we have dyno'd. With these filters, horsepower and torque are increased and are smoother all the way up the curve. They also take up less room than the pod style filter and are cheaper.
