With all IndyCar Series engines now required to have twin turbochargers from this year onward, one would figure that Honda, which had previously ran a single-turbo powerplant over the last two years, is at a disadvantage against Chevrolet, which has been using a twin-turbo since its return to IndyCar in 2012.
But in an interview with IndyCar.com, Honda Performance Development technical director Roger Griffiths says that the time spent with the single-turbo has given Honda a “really good insight” into how to go about developing its new twin-turbo, which has already been tested twice on the road course at Sebring and on the oval at Fontana this off-season.
Furthermore, Griffiths says that the new engine is already stacking up nicely against the 2013-spec single-turbo, which helped take Scott Dixon (pictured) to his third IndyCar championship.
“We had evolved the 2013 spec engine with a single turbo to a very high level of development so we had a very high bar that we had set for ourselves in terms of drivability and response and those kinds of things,” he said.
“We were pleasantly surprised by the rate at which we reached the same sort of level of performance with the 2014 engine given that it was all kind of new.”
Griffiths also gave credit to Simon Pagenaud from Honda-powered Schmidt Hamilton Motorsports. The French driver, who finished third in last year’s standings, took time after Thanksgiving to meet with HPD engineers and provide them with feedback.
“Our guys could come back from a test and say, ‘OK, these are the top five complaints and what needs fixed.’ But it’s our translation of what the driver is saying to the design engineers,” Griffiths explained.
“Sitting down with 10 of our young engineers, they quickly get past the shock of an IndyCar driver sitting down with them in the meeting room and it’s just another person trying to do a job. They’re hearing from the person driving the car what they want. It really helps our relationship with the drivers. Simon gave us some good pointers.”
After losing the last two IndyCar manufacturers’ championships to Chevrolet, it’s clear that Honda is doing all it can to wrest the title away from the Bowtie in 2014.
As for Chevy’s view, their program manager, Chris Berube, told IndyCar.com that while they saw advantages in both the single and twin turbo engines, they went with the latter because “[they] believed there was a better application of that.”
Now, as his company enters its third season after re-entering open-wheel competition, Berube feels that their experience with the twin-turbo will give them an early-season edge.
“I think we have a good understanding of the twin turbo application and that in itself will be an advantage initially,” he said.
The two-day Chris Griffis Memorial Mazda Road to Indy Test concluded on Sunday at the Indianapolis Motor Speedway road course.
Combined times after the two days of running are below, with Nico Jamin (Indy Lights Presented by Cooper Tires) and Oliver Askew (Pro Mazda Championship Presented by Cooper Tires) remaining on top from Saturday to Sunday, and Darren Keane (Cooper Tires USF2000 Championship Powered by Mazda) supplanting Andres Gutierrez at the head of that field.
Previous notebooks are linked here (Friday, Saturday), with additional Sunday notes to follow.
Several drivers pulled double duty between series, namely Parker Thompson (Exclusive Autosport in Pro Mazda and USF2000), Carlos Cunha (Juncos Racing in Indy Lights and Pro Mazda) and Aaron Telitz (Team Pelfrey in Pro Mazda, RJB Motorsports in USF2000). Telitz (above) added a run in Pro Mazda in Team Pelfrey’s No. 82 car; the Wisconsinite has done a lot of the series’ testing for the new Pro Mazda Tatuus PM-18, and had hoped to run all three series. We’ll have more meanwhile on Thompson and Exclusive’s double in the days to come; the Michael Duncalfe-led team out of Saskatoon, Saskatchewan was one of three new Pro Mazda teams adding those cars to USF2000 efforts (Pabst Racing, BN Racing) this week.
There were a handful of drivers that changed cars or teams for Sunday’s second day of the test, primarily in USF2000. While Keane ran both days at Newman Wachs, the Brian Halahan-managed team ran David Osborne and Oscar DeLuzuriaga in the Nos. 37 and 38 cars, taking over from Jake Craig and Max Peichel. Osborne switched from Team Pelfrey, where he ran Saturday, and where Jacob Loomis ran Sunday. Justin Gordon ran a second Exclusive Autosport chassis, switching to the No. 90 on Sunday after running the No. 92 Saturday.
The PM-18 best lap set by Askew is more than three seconds faster than the series’ official track record (Pato O’Ward in 2016, at 1:22.8800, 105.941 mph). Askew’s best time of 1:19.8142 averages 110.010 mph around the 2.439-mile circuit. Neither the Indy Lights nor USF2000 cars eclipsed the existing lap records in those categories.
Drivers largely extolled the PM-18’s outright pace and potential with the horsepower upgrade, in what is a significant step forward for the series. “Following prototype testing of the new PM-18, I believed that we had a special race car and this weekend’s testing confirms that,” said Dan Andersen, Owner and CEO of Andersen Promotions. “Based on team and driver comments, this is a fantastic race car and I am very pleased with what Tatuus, Elite Engines and my team have assembled. It fits perfectly in between the USF-17 and the IL-15 in terms of lap times and, more importantly, it takes what a driver learns in the first step and introduces higher HP, higher grip and higher aero. This will be a great training car for years to come, and seeing our program now with three excellent and well-designed cars is very satisfying to me.”
Keane, one of the few veterans (relatively speaking) within USF2000 was plugged in this weekend as the only driver outside Pabst Racing to threaten the top of the timesheets. “It’s a good boost in confidence for me heading into next year. I am really happy with how everything is going with the team. They are a great group of guys and it’s just really good to see us improving and being where we want to be,” he said.
Rinus Veekay hailed the Indy Lights Dallara IL-15 Mazda this weekend in his first test there, although the talented Dutch teenager may well focus on Pro Mazda next season and shoot to win that championship, and continue his battle with Askew established in USF2000. “The car is very nice, quick,” noted VeeKay. “You can really feel the downforce and it was a pleasure to drive.”
The MRTI is done with official running for the year, but the $200,000 MRTI Scholarship Shootout remains in December at Wild Horse Pass Motorsports Park, the former Firebird Raceway, outside Phoenix. The winner of that will get a ticket into USF2000 for the 2018 season.
Full MRTI spring training will take place at Homestead-Miami Speedway in February 2018, with undoubtedly a bevy of driver and team announcements to come over the following months.
