RA­CEPAK, THE COM­PANY THAT REVOLUTIONIZED DRAG RACING WITH THE FIRST DATA RECORDERS MORE THAN A GEN­ER­A­TION AGO, HAS MADE TUN­ING AND MONITORING VIR­TU­ALLY ANY KIND OF RACE CAR EASIER THAN EVER WITH THE IN­TRO­DUC­TION OF A PAIR OF IN­NO­VA­TIVE NEW PROD­UCTS: THE DRAG SMARTWIRE AND IQ3D DRAG LOGGER DASH.

The Drag SmartWire serves as a drag ve­hi­cle’s power dis­tri­bu­tion cen­ter. Equally at home in drag­sters and door cars, it elim­i­nates the need for fuses, re­lays and break­ers and takes the headache out of wiring any race car. “It’s the eas­i­est way there is to wire a race car—any car,” says Ra­cepak Sales and Mar­ket­ing Man­ager Chris Vopat.

“It elim­i­nates ex­tra weight, un­nec­es­sary com­plex­ity and all of the ex­tra com­po­nents that used to make wiring a has­sle: fuses, cir­cuit break­ers and re­lays. It talks to your ECU and your EFI sys­tem, and if you have a Ra­cepak dash or data recorder, need­less to say, it works per­fectly with that, too.”

The Ra­cepak Drag SmartWire fea­tures a to­tal of 30 out­puts and 12 in­puts, and all in­puts and out­puts are user-de­fin­able, en­abling com­plete con­trol of the ve­hi­cle’s power needs, and it’s pre-pro­grammed for most drag-car func­tions. The unit comes com­plete with a wiring har­ness de­vel­oped specif­i­cally for cars that com­pete on the drag strip.

“It's preprinted for each func­tion, the trans-brake and all the func­tions a typ­i­cal sportsman racer re­ally needs to have,” Vopat says. “You can then spec­ify your own custom pa­ram­e­ters for each of the 30 cir­cuits once you have it in the car: the am­per­age, the volt­age, any­thing you want.”

Just plug in a lap­top, and you'll see ev­ery func­tion that goes out to the ve­hi­cle. Then you can then eas­ily mod­ify each cir­cuit’s pa­ram­e­ters in count­less dif­fer­ent ways.

For ex­am­ple, you can pro­gram your fan cir­cuit to be ac­ti­vated from a cer­tain range it reads from your wa­ter tem­per­a­ture. If tem­per­a­ture is read­ing a high num­ber when the ig­ni­tion is switched off, the fan could be pro­grammed to run for any length of time or until the en­gine reaches any tem­per­a­ture you spec­ify. “The pos­si­bil­i­ties to con­trol each cir­cuit are vir­tu­ally end­less,” Vopat says.

Ra­cepak’s IQ3D Drag Logger Dash has be­come the go-to en­try-level dash logger for week­end war­riors and bracket racers, with all of the func­tions the av­er­age sportsman racer could pos­si­bly need. It’s com­pact, all-in-one de­sign has the same state-of-the art de­sign as the IQ3 dash the pros use and a built-in data logger. Data is dis­played on four user-de­fined pages and stored af­ter each run on a mi­croSD mem­ory card.

“With the Drag Logger Dash, you can set warn­ing lights for high or low tem­per­a­tures and high or low pressures, plus it fea­tures pro­gram­mable shift lights,” Vopat says. “You de­ter­mine what you want to mon­i­tor and ex­actly where you want to see it. And for data col­lec­tion, there's a front­mounted mi­croSD card that you can take out and plug right into your com­puter. There are four screens to tog­gle be­tween, and in each there’s an rpm sweep and gear in­di­ca­tor. Each of the four pages has five pro­gram­mable ar­eas for just about any­thing a racer could think of. You could have, say, the ve­hi­cle speed in the lower left cor­ner, and you can la­bel it ‘speed’ or ‘MPH’—any­thing you want.”

An­other in­valu­able fea­ture of the Drag Logger is an in­ter­nal pro­ces­sor that can com­mu­ni­cate with any af­ter­mar­ket EFI or OBD-II. “The older line of dashes didn’t have that. You'd have to buy an ad­di­tional mod­ule to read an ECU or dif­fer­ent EFI,” Vopat says. “The IQ3D Drag Logger has it all built right in.”
