RISI COMPETIZIONE LONG BEACH GRAND PRIX PREVIEW - 2017
A Race Engineers' Perspective
Risi Competizione Ferrari 488 GTLM No. 62: Giancarlo Fisichella (ITA)
Toni Vilander (FIN)

(Houston, Texas, April 3 2017)...Rick Mayer, race engineer of the Risi Competizione
No. 62 Ferrari 488 GTLM team, gives us a preview of this year's Bubba Burger Sports
Car Grand Prix at Long Beach race, April 7 - 8, 2017.
Teammates Giancarlo Fisichella (Italy) and Toni Vilander (Finland) will again drive
the Risi Competizione Ferrari 488 GTLM in Round 3 of the 2017 International Motor
Sports Association (IMSA) WeatherTech SportsCar Championship series, in the GTLM
 class. They finished third in the recent Twelve Hours of Sebring, third in the 
Rolex 24 At Daytona in January 2017, and won the GTLM finale, Petit Le Mans, at 
Road Atlanta in their last race of the 2016 WeatherTech race season.
General: The Long Beach race will have 35 cars, including nine very competitive 
GTLM entries from five manufacturers. This is a three-class race: GTLM, GTD and 
DPi. This will be the largest field we've had here since the American Le Mans Series
(ALMS) with the addition of the GTDs this year. The additional Pro-Am GTD class 
will make this short 100-minute race much more difficult for all the GTLM cars than
in past years when it was just Prototype and GTLMs classes. Pit boxes will be small
and no GTLM or GTD cars have both a clear IN and clear OUT with the split pit opening
under the safety car. When pits open for 'GT' you'll have 25 GT cars all coming 
into the pits at the same time. The last pit stop for all GT's will be pivotal and
somewhat of a wild card as you can't control where cars that may hinder your pit
 stop are in the queue coming into the pits.
The track: The entire Long Beach 1.97-mile, 11-turn, street circuit is passenger
 car filled most of the year. Cars, trucks and busses idle at the traffic lights
 and occasionally drop fluid (oil, fuel, and engine coolant) creating a low grip
 surface. The crowning of the road leads to some off-camber corners upsetting the
balance, typically mid corner out. The track is bumpy, in a washboard fashion, quite
different than Sebring. The track will be really dirty, and cold, for our 'track
 cleaning' 7:40 a.m. two hour first session. Like most temporary street circuits,
grip changes with each session and you really only start seeing a partial picture
of what the car is doing at the end of the two-hour session, after the track has
 cleaned up and some rubbers has gone down on the surface. This track's tendency
 is to move toward understeer for the race. How much is the question? The front 
straight is slightly curved but is full throttle with a very high top speed. A good
exit off the 40 mph hairpin is essential for overtaking into Turn 1. There are very
few passing opportunities here. Qualifying position is super important as is great
pit work.

 Long Beach race

GTLM Competition: The entire GTLM field is on different Michelin tires then the 
2016 race. We've all run these tire options starting at Daytona so they are not 
'new' tires, just new to Long Beach. All the GTLMs were new (2016 spec) last year
and this will be everyone's second trip to Long Beach (except Porsche), so we'd 
expect all the setups to improve.
The BoP (Balance of Performance) keeps evolving, trying to sort out what's an unfair
BoP advantage, what's a good setup and who is not showing true pace (sandbagging)
is not an easy puzzle for IMSA to unscramble. The first three tracks of the season
are all anomalies and difficult to adjust BoP from. Daytona is all about banking
 speed, Sebring is super bumpy and hard to have a good setup for all the conditions
and Long Beach is a true street track with unique setup requirements that relate
 to no other tracks. The recent BoP change, prior to this race, gives BMW and Ferrari
a bit more power and takes some power from Porsche. Porsche also got a small minimum
weight increase. Performance wise, Ford and Corvette are unchanged from Sebring.
Sebring was a difficult race to gauge BoP as the conditions were ever changing. 
For sure the F488 GTLM did not have straight line performance parity with the others,
but the recent BoP helped addressed that. The Ferrari, with closer power parity,
 should be competitive this year at Long Beach. Compared to last year the Ferrari
is up on power and heavier. The BMWs received a power increase (more boost) for 
this event. BMW has historically been good at Long Beach and this year should be
 no exception. They are lighter and have more power than last year. The Corvettes
were competitive last year (Long Beach) and this year are up on power and down on
weight (same BoP as 2017 Sebring) compared to the 2016 race. Ford dominated the 
timing sector data last year but had reliability issues in the race. Ford is heavier
and has less power (boost) than last year's Long Beach race. Porsche has an all 
new mid-engine car; they are heavier and have the same power as last year.
Setup: All the GTLM competitors have been here before, all except Porsche, with 
their current model of car. Setups will evolve from the knowledge gained last year.
The car needs good power down, particularly off the hairpin to either pass in braking
into Turn 1 or to keep from getting passed. All the corners are slow (mainly 1st
 or 2nd gear) so it's brake, turn-in and back to full throttle quickly. While some
apex curbs are usable, some you have to stay off of, as they are large (huge) bolted
down temporary curbs. The car needs some change of direction stability in the last
section leading up to the hairpin, and around the fountain, so you can't run too
 soft of a setup. You need good brakes but you don't trail brake into the corners
here as much as other race tracks so rear stability under braking is not 'as big'
a concern. Braking zones are bumpy (washboard) further complicating the setup. Reducing
the low speed under-steer coming off the brake to the apex and having good traction
and corner exit (without a lot of understeer) are keys to quick laps as all the 
corners are all essentially short duration. You always run maximum downforce here
even though it's tempting to try and achieve a higher front straight top speed by
trimming aero.

The race: Is only 100 minutes. There is no minimum driver time in the Pro classes;
if there's any caution periods, that open the pits, everyone will likely change 
drivers. One driver could essentially do the entire race. The fuel will be tight
 as the fuel tanks are small and we cannot run much more than half a race on a full
tank of VP E20 fuel. The first stint will be shorter due to fuel used for the reconnaissance
lap and the two pace laps. A timed fuel fill and a driver's change will be done 
on the one and only stop. That's if it's green all the way, and if that's the strategy
you choose. The biggest change from recent Long Beach races is the addition of the
Pro-Am content GTD's. This will make the early stages of the race extremely difficult.
All the Am GTD drivers will likely qualify and start the race, as you want your 
Pro's in at the end. Once the GTLMs get up to the back end of the GTDs potential
 problems will start. It will be very difficult for GTLMs to pass here as this circuit
is tight and the GTDs have comparable straight line speed. If managed correctly,
 the two car GTLM teams could have an advantage by being able to split their strategies,
in yellow situations or even under a full green flag race. They can hedge their 
bets, when the strategy call isn't obvious.
The Ferrari should be quick here; Risi Competizione has won this race in class in
years past and fared well last year, finishing third. We need a good, solid and 
clean run, and a little luck, to hopefully continue our podium streak this year.
