Fast track

Post by Collin Jackson » Thu Feb 15, 2018 3:42 pm

Looks like they are re-difining the GT3 class again.
Toyota 1600 and 1800 weights go up 50#
All the Mazda Rotors go down 40-100# depending (13B or 12A)
Everyone else seems to be unaffected.

IE: What were these changes designed to do?

Matt

Will definitely make the Mazda guys happy, but it will also piss off the Toyota guys no end for the lead!
We were all pretty much the same trap speed at Indy so why pee off the Toyota duds.
Are the rotary guys complaining as I have not heard anything?

1. #23291 (Samuel Fouse) 1.8 Liter Motors
In the GT3 spec lines, change spec line weight for all engines as follows:
1.8l motors (1750cc - 1849cc) to 1960 lbs.
1.6l motors (1550cc - 1649cc) to 1690 lbs.
13B Peripheral/Bridge Port to 2200 lbs.
13B Street Port to 2090 lbs.
12B Street Port/Bridge Port to 1960 lbs.
12A Peripheral Port 37mm SIR to 2150 lbs.

From the runoffs archive up to 2014, he had 1 start, 1995 in GT4 in a Mazda GLC, completed 1 lap, and was a DNF. He was listed in the SE Division. Looking at the entry lists for 2015-2017, he's not listed. How is it possible for somebody who isn't an active driver, ask for weight changes on multiple cars, and get approved?

I am showing he ran 2 weekends in 2017, finishing 10th in the SE division, driving a Mazda Protege.

He must have had a very large check mailed along with letter # 23291

I don't know this guy from Adam, but is this Fouse guy maybe a shop owner/car builder for other GT cars? (who races rotaries in FL, and who works on those cars?)
I often see letters written by shops/builders on behalf of the competitors in their care.

Who is on the GTAC? I find that most of these committees tend to listen to the guys that are running in the class.

Hard to figure what the GTAC is thinking. Sam Fouse is developing a 1.8 Mazda, hasn't run it yet that I know of. The Toyotas' trap speeds were decent at indy-all had troubles. The rotaries seem to be pretty good to me -especially the peripheral port. Sorry, but it just seems to me that Collin was the only GT3 that totally had his act together at Indy. Maybe I should have asked for a 2.7 liter since all of my transmissions broke and I had to run with not quite 2 forward speeds at Indy.

i do know MIchael Heitzman has a Mazda engine package he has been working on but I don't know how these rules effect it. I guess the biggest question is what did the smallest engine in the class get weight?

Joe,

It may make all of our effort worthless. The package we are developing will now have 50lbs added and the package we were using would lose 100lbs. In effect, either engine used would result in the same car weight. I believe Wolfgang will have a weight increase which I do not think is right and the goal posts have moved again in regards to weight groupings just when the basic rules appeared to be stable.

Right now I am looking at the options and waiting for the official FasTrack publication and will then look at what to build to replace the motor we lost at Portland. I have a spare motor in the car now for Willow Springs.

1.8's under 1800 will gain weight and 1.8's over 1800 lose weight. So the hard and fast line at 1800cc relating to car weight has been moved down to 1750cc.

I have no idea what the rotary weight changes do.
