No recorded track times that I could really find…

Alright, interesting info I guess. I’m pretty sure they measured it with a tank of gas since they had an actual car, but is that super super important?

Add 200 lbs for a tank of gas? that’s 33 gallons give or take a bit. Pretty sure it didn’t have that big of a tank on it though.

Nope, not even half… 15.2 gallons, if I recall correctly.

Thats 276 lbs for gas and one redneck. seems legit.

Perfect. Wife beater an’ all. Yeee hawwww.

You guys maybe right… When I looked up the stats of the car it said something about it so I thought I would add it in. I may even be wrong about it… Idk. Lol

I love these types of tests… do you test acceleration on a regular track? Or at the dragstrip with ungodly amount of traction it has?

I’m thinking he’s just using the in-game benchmark test which calculates the figures without having to hit the track.

When you do it on track with instant replay you get totally different numbers

Yeah however T10 does the benchmark isn’t always 100% accurate. You can really notice this when you start playing around with the gears in cars. Sometimes just changing the FD one hendredth can decrease or increase the acceleration times by around 2-3 tenths of a second.

I had to google what a “IROC Z” was :))

Unfortunately

This body style Mustangs owned the IROC-Z back then. Especially if that Mustang came from factory with 3.55 or 3.73 gears. I whooped a co-worker IROC-Z (his had 350 not 305 engine/it was auto {only trans for 350 engine}) with my 89 GT 5.0 manual trans with 3.73 gears.

The IROC-Z in Forza they used is a 350 with auto. That’s why car a 4 speed stock.

benchmark figures should be used as a ball park figure.

The extra weight in the Forza car was the owner’s Whitesnake cassette tape collection.

Yeah I just use the benchmark. And if I remember right the IROC Z only came with a 4 speed auto. But there were also 3 motors for the car. I think the only diff was HP. I think one was 225. Then another was I think 235. Then 245hp

There were 4 engines. The 350 with 4 speed auto only, the 305 (auto or 5 speed), 4 cylinder (used early on & replaced by V6) & V6.
