After five years of our no-holds-barred Tuner Shootout event, we’ve decided it’s time to mix things up a little. Just like in previous years, the Shootout is being held in the Phoenix, AZ area, with UMS Tuning hosting the dyno competition (March 30th, 2012) and NASA AZ hosting all the on-track action at Firebird Raceway (March 31st, 2012). The Shootout is also still going to feature an autocross, a time attack, and a drag race, along with a power test on the dyno.

But to put a new twist on the event, the 2012 Shootout will cater to street driven yet still highly tuned vehicles, rather than the all-out race cars that have dominated the event in years past. This means the entrants this year will be cars with full OEM glass, OEM fuel tanks, and OEM lighting (headlights, turn signals, and taillights), full interiors from the front seats forward (aftermarket seats and harnesses permitted), and a full exhaust system (no cut-outs or bypasses) including a functional catalytic converter and muffler.

To measure what we consider two of the most important aspects of any street driven tuner car, we’ve added an emissions component (using a tailpipe sniffer) and an exhaust sound level component (using a dB meter) to the dyno competition. As a result, the winner of the dyno competition may not be the team with the most powerful engine, but rather the team with the best combination of power, low emissions and legal exhaust dB.

Once again Continental Tire is the title sponsor, and given that this year’s event is meant for street driven cars, we’ll be requiring all teams to compete on Continental street tires (most likely their Extreme Contact DW, which come in a wide range of sizes).

There will be four events that will judge the performance of your car. Dyno (25 points) + emissions (10 points), Drag (75 points), Autocross (100 points) and Time Attack (100 points). The car with the highest overall score from these four events will win the overall championship. Trophies will also be awarded to the highest scoring FWD, RWD, and AWD cars.

The Rules:

• Your car must be equipped with:

OEM windscreen and windows (Lexan or other lightweight glass replacements not permitted).

OEM fuel tank (fuel cells not permitted) and unleaded or e85 fuel.

OEM lighting (headlights, turn signals, and taillights must all be functional, as is required on a street legal vehicle).

A full interior from the front seats forward (aftermarket seats and harnesses permitted. Roll bars and roll cages may be added, but interior trim can only be modified to the extent required to fit these safety items).

A full exhaust system (no cut-outs or bypasses permitted), including a functional catalytic converter) and muffler.

• You may put any driver you want in your car and there is no requirement for the same driver to pilot the vehicle during the 3 timed events. You can, therefore, opt to have a drag racer do the 1/4-mile runs and then swap in a Time Attack driver for that portion of the event. You may also choose to have different drivers pilot your car during the same event (ie. you can have more than one driver make a pass during the drag runs, but your team will still be limited to 3 passes total).

• You may change the aero, suspension, brake and ECU settings of your vehicle between events in any manner you wish. You can, for example, choose to remove the rear wing for the 1/4-mile runs and put it back on for the Time Attack. Similarly, you can run a high boost map on the dyno and then run a lower boost map for the autocross or time attack events.

• You are permitted to repair your vehicle between events, but you cannot change major mechanical parts between events unless it’s a necessary repair to complete the competition (you can fix stuff that breaks, but we don’t want teams switching turbos, rear ends, or other major mechanical components between events because we feel that places too much stress on the teams).

• Continental will be providing the street tires for this event and you will have to run on one set for the entire event.

If you think you’ve got a car worthy of entry into this event, please send us the following:

- Photos of your vehicle including exterior, interior and engine bay shots
- A list of modifications made to your car
- Why we should pick your vehicle for this competition

Email your submissions to peter@modified.com

Please be aware that the cost of attending this event is left up to you but we guarantee a good time with some awesome racers and some great exposure in the magazine for all contestants.

^Thanks for the offer. I love the Phoenix area. Without sponsors, it just won't happen for me. I'd have about $4K in tranny and diff stuff plus $2K in shipping costs. Would do it if I could put something together on the sponsorship side. I'd love to get a good driver to take the car out and see what it can do - a 700HP RX7 would give the competition something to think about.

Without the above work though, we'd just be asking for trouble.

Post up some specs and pics! I'll forward to the editor of Modified... those I think could represent this community.

I've got the perfect customer's car for this. It meets all the criteria, and is a short road course car. Did 370rwhp @ low boost yesterday stopping @ 5800rpms before the WG started to creep a couple psi..

IMO, the car will need to pass emissions while running high 10s, low 11s and be a track monster to be competitive. No small feat! Actually, an E85 setup might just be the ticket! Should help with the emissions issue, correct?

I'm thinking the big-power E85 Lambo and Supra guys in the area will be all over this. Many have made the switch to Pro EFI which compensates for different fuels.

Does anyone have advice on which 3" high flow cat flows the best? . . .

Best or Cheap? Cheapest would be friend and truck with trailer. Best would probably be Reliable Carrier's enclosed semi trailer.

IMO 95% people who mod there car get rid of their cat first....... lol

Looks like it should be metal for a rotary, can anyone find something that flows better than this? http://www.verociousmotorsports.com/...6647&fromsla=T

Scoring:

The fastest team from the Autocross and Time Attack events will be awarded 100 points. The fastest team from the Drag event will be awarded 75 points. The winner of the Dyno competition will be awarded 25 points. The winner of the emissions test competition will be awarded 15 points. All other teams will be scored as a percentage of the winning values. Finally, teams will be penalized 1 point for every dB they register over the 95 dB limit.

The points formula used for the three timed events is as follows:

(Winning car’s time) ÷ (your car’s time) X (max # of points for the event)

Example 1 – the winning 1/4-mile time is 10.998 seconds and your car posts a best of 12.327 seconds. As a result your car will be awarded 66.914 points (10.998/12.327*75).

Example 2 – the fastest Autocross time is 42.025 seconds and your car posts a best time of 47.899 seconds. As a result, your car will be awarded 87.736 points (42.025/47.899*100).

Example 3 – the fastest Time Attack lap time is 65.351 seconds and your car turns a best lap time of 67.012. As a result your car will be awarded 97.521 points (65.351/67.012*100).

We feel this system is fairest because it recognizes gaps in speed, unlike a system where 100 points is awarded for 1st, 80 points for 2nd, 70 points for 3rd, 60 points for 4th, etc. Under our system, if you win an event by a large margin you will score proportionately more points in that event than your competitors.

Dyno & Emissions Competition: Since this is a non-timed event, we will be using our usual ‘Power Under The Curve’ method. For the purposes of this competition, we define this as the sum of all HP readings produced on the dyno in 100 RPM increments for the best 3,000 rpm range for your engine. By totaling power in this way, we will be evaluating how much useable power each engine produces in the RPM range it’s most likely to be operating in during the timed events.

Example: The most powerful car posts a power under the curve value of 20,000 HP (in its best 3000 RPM range in 100 RPM increments). They are awarded 25 points for this part of the event. Your car posts 18,000 HP under the curve. As a result, your car will be awarded 22.5 points (18000/20000*25) for this part of the event.

Emissions Test: While your car is still on the dyno (immediately after your final dyno run), we will measure HC, CO and NOx. This will be done using a 5-gas tailpipe analyzer during a 90-second idle test (approx. 900 RPM) followed by a 90-second 3000 RPM 100 lb/ft (as measured on the dyno) test. Your car’s HC and NOx readings (in ppm) will be totaled and the team with the lowest overall emissions will be the winner and receive the maximum 10 points for the event. CO will be recorded and reported on in the story so that readers see all three gases normally included in an e-test, but we won’t be using CO for scoring.

Example: The cleanest car registers HC of 10ppm and NOx of 15ppm during the idle test and HC of 15ppm and NOx of 25ppm during the 3000 RPM loaded test for a total emissions test value of 65ppm. As a result this car is awarded 10 points. Your car registers HC of 14ppm and NOx of 21 at idle and HC of 20ppm and NOx of 44ppm at 3000 RPM for a total of 99ppm. As a result, your car is awarded 6.6 points (65/99*10) for this event.

Exhaust dB Test: Once the emissions test is complete we will measure exhaust dB the same way the state of California does, where the legal limit is 95 dB. Teams will lose 1 point from their Shootout total for every dB they exceed this limit. The dB test will be done as follows:

The dB meter microphone shall be at the same height as the exhaust outlet and no closer to the pavement than 8’’ when the exhaust outlet is lower than this height. The microphone shall be positioned with its longitudinal axis parallel to the ground, 20’’ (+/- 1’’) from the nearest edge of the exhaust outlet and 45 degrees (+/- 10 degrees) from the axis of the outlet. The engine shall be at a normal running temperature with the transmission in neutral. The test shall be made at an average steady-state engine speed of three-quarters of maximum rpm.

The Classes:

All teams will compete head-to-head for the Overall Champion trophy. Trophies will also be awarded to the highest scoring AWD, RWD and FWD teams.

My customer is in, but to make 500+rwhp with a cat is going to take 100 octane.

Waiting on the other pictures from him to post up. I think this car will do well; GTX35R with a Tial 1.03 makes full boost by 3200rpms, and the car is setup for this track..

Makes me glad he went with the waste-gate reroute..

They are also adjusting the rules to be more specific. Auxiliary injection is acceptable, as long as primary fuel is from the OEM gas tank, then meth injection as auxiliary at high boost is fine. So 93 octane and meth injection will be better than E85.
