Last week, we started our first round of power mods to Gotta Have It Race and Gotta Have It Street. We installed two cold air intakes from JLT, one in Carbon Fiber and one that is painted Gotta Have It Green. We also installed two XCAL3 tuners from SCT. We loaded each SCT XCAL3 with base 93 octane tunes and with 93 octane tunes for a JLT Cold Air intake. The JLT Cold Air Intake installations were a breeze and took practically no time. Our install video for these JLT Cold Air Intakes will be coming soon to CJ's YouTube channel!
Next, we installed both of the XCAL3s and loaded the 93 octane JLT Cold Air tunes into both cars. Unfortunately, neither tune was perfect, and we definitely did not want to race either car until those tunes were perfected. So, the day after we loaded the tunes, we gave Jay from JLT a call, and he got us on the right track with a great 93 octane JLT cold air tune for our manual transmission Gotta Have It Race. Thanks for the help Jay! Since we were not able to get the automatic transmission 93 octane JLT Cold Air tune perfected for Gotta Have It Street, we decided to remove the intake and load a base 93 octane tune in Gotta Have It Street for our trip to the track on Saturday.
Bright and early on Saturday morning, Rich, Rick and Steve loaded up both sets of Race Star Industries Dark Star wheels with drag radials, some tools and a tent into Rich’s 2012 Ford Raptor and started the 1-1/2 hour trip down to Cecil County Dragway with Gotta Have It Race and Gotta Have It Street. We arrived at the track around 9:30 a.m. and proceeded to unload the truck and setup our pit area. We also met up with our good buddy Brent and his 2011 5.0L Race Red GT. Once we were setup, we put our 17"x4.5” Race Star Industries Dark Star wheels with 185/55-17 M&H Racemaster Front Runners on each car. Gotta Have It Race was prepped with 15"x10" Dark Star wheels with 275/50-15 Mickey Thompson ET Streets, which fit perfectly because we used BMR’s Rear Sway Bar Relocation Kit. Gotta Have it Street was prepped with 17"x9.5" Dark Star wheels with 275/40-17 BF Goodrich drag radials.
The last time we had Gotta Have It Race to the drag strip was on May 12th at Cecil County Dragway. If you remember, Bill was able to go 12.05 @ 116 MPH that day. Gotta Have It Race used the same wheels and tires, but only had a base tune that was used to raise the rev limiter so that we wouldn’t hit it in 4th gear before we got to the finish line. With a full tune installed with our SCT XCAL3 plus the addition of our JLT Cold Air Intake and Flowmaster Hushpower full catback, we were hoping to get a much better time.
Even though it was still only 10:15 in the morning, it was very hot and humid already. Rich knew that he was going to have a challenge if he was going to beat Bill’s time in Gotta Have It Race, especially since he had not had the chance to take Gotta Have It Race down the track at all yet. Rich started his first pass by working on Bill’s recommendation of launching Gotta Have It Race at 4500 RPM and letting the clutch slip just enough without letting it bog.
On the first run, it seemed that 4500 RPM was just too much for the track and the Mickey Thompson tires to handle, as Rich had instant wheel spin and only managed a 2.41 60’ time on his way to a 13.42 @ 113.6 MPH. Rich kept working on his launch, trying to find the best combination of RPM to launch at with just the right amount of clutch slippage. Thankfully, Rich had no problems with the shifter during his maiden passes in Gotta Have It Race, and found the Barton shifter and shifter bracket allowed him to power shift without having to worry about missing a gear.
By the time that Rich found the right combination of RPM and clutch slippage to get a good 60’ time, it was 1:30 in the afternoon and the heat and humidity were in full effect. He was able to make two decent back to back passes: 12.24 @ 114.1 MPH with a 1.84 60’ and 12.21 @113.9 MPH with a 1.85 60’. Earlier in the day, Rich set a new best for MPH with a 116.76, which beat our previous best of 116.05. We know that the new JLT Cold Air Intake and SCT XCAL3 tune are making good power, and even with the additional heat and humidity, we were able to post a new best MPH.
Gotta Have It Street had not been to a track since the NMRA event at Maryland International Raceway on May 6, where we ran a best ET of 12.89 @ 104 MPH and a best MPH of 12.93 @ 109 MPH in completely stock trim. Rick made the first pass at 10:15 a.m. and ran what would be our best time of the day for Gotta Have It Street, a 12.49 @ 112.35 MPH with a 1.93 60’. That first run of the day was a big improvement over our previous best time. Even with the additional heat and humidity, we were able to knock off 0.4 of a second and gain over 3 MPH with just a 93 octane tune from our XCAL3! The tune helped improve the throttle response for Gotta Have It Street and increased the shift points from 6400 RPM to around 6800 RPM, which kept the 5.0L Coyote engine in its power band longer.
On the first run of the day, Rick brake torqued Gotta Have It Street at the start line. With the stock converter, we could only get the torque stall up to around 2000 RPM. Rick hot lapped the car because he wanted to see if he could get a better launch (and ET) by trying to flash the torque converter instead of brake torquing. The second run used that launch technique and produced an almost identical 60’ time, a 1.96 on the way to a 12.54 @ 112 MPH. We let the car cool down for a little bit, hoping that it could cool enough to make up for the rising heat and humidity. Just before noon, Rick made another pass and went 12.51 @ 112.4 MPH with a 1.96 60’. It was not an improvement, but gave him three passes that ranged from 12.49 to 12.54. Consistency like that is going to come in handy when Gotta Have It Street races in the Roush Super Stang class at the NMRA event in Milan Michigan in a few weeks.
