Everybody knows a properly tuned 340/440 on good fuel traps around 118 mph.

who proved me wrong? post another roll race with a tuned 440i vs a stock supra. I'll wait.

340/440i will not trap 118mph without meth also.

M240i will, but not the 340/440i.

Also you have DA, temp changes in most places as well. If it's consistently lower than 80F where you live with low DA, then yeah you'll run faster times with higher trap, but the avg places have high DA with temps ranging from 80-95F.

A FBO 340/440i on both mhd/BM3 here on 93 Oct have trapped a max of 114mph here where I live, temps were around 80-85F area at night.

OP asks how could this happen
We give a bunch of reasons why it could
Pitchforks come out

Let's be fair here my MPPSK traps 110-112 mph on 87-88 octane.

Don't you think with a full 100 HP more it couldn't trap 118 mph?

I am just surprised how a 450 HP car weighing only 1615 kgs couldn't trap 118 mph specially as mentioned my MPPSK traps 112 mph on crap fuel and poor traction.

The M240i is lighter than the 340i by only 70 kgs so that shouldn't make a big difference.

Just because it's fresh on my mind from watching this over the weekend, here's a video to illustrate my point.

1/4mile trap:136
Roll racing trap: 136, can't even break 140

So again, your quarter mile times don't translate. Your assumptions don't translate. They didn't race in Egypt, they raced in California on California fuel. You're saying what you think should happen even though a video shows that it's not always the case. You can keep beating the dead horse if you want but at the end of the day, it happened. Sorry you can't deal with it, but physics don't need you to agree for it to be real.

You guys have more track data than me so I am not doubting your findings.

I am just surprised how an extra 100 HP (30%) can't get an extra 5 mph even according to physics.

Forgot to post this; dude on BM3 stage 1. Stage 2 decatted he’s pulling easy. Let’s hear the nonsense excuses “it is what it is”

Realistically you'd want the temps to be in the 20s and DA between 1000-2000 to simulate real drag strip conditions.

Colder temps and negative DA is basically cheating

Thats bm3 st2 ots 450crank

yokata · 05-26-2020, 09:51 AM

And this is st2+ 505 crank but car dies in top end but u see in hotter temps and higher DA car cant beat its best time with 50hp more so it depends on too much factors....on the street though things is little bit different

IMS-340C · 05-26-2020, 11:15 AM

I think that's a realistic result of 340i stage 2 vs Stock Supra.
