What was the mph?

With a terrible launch (spinning all through first) the best I could do with 350rwkw and running VERY cheap 235 tyres was a 12.2 with a 60' that I think started with a 2.....
MPH was around the same as I get usually of 119.

Good tyres would defo get the et down to high 11's.

From memory up around 118-121mph 

 

A genuine 300rwkw should net that figure in a full weight falcon 

 

A 350rwkw falcon should get up around 123-125mph 

 

A 400rwkw falcon should go 129-132mph

Mate those are very happy figures and would love to see time slips with those claims!

My pics attached.

This is what a genuine 350rwkw (ok so 346.8rwkw) E85 burning, full weight FGX does.

You're a bit off on your kW to mph figures from what I've seen an experienced.

There's a few ~480kw full weight 8's over here that are running mid to low 10's and they're 130-133mph. I don't see how a Barra with ~80kw less could keep up? b93020e39c6032837e5d4c4150f008c5.jpgcd2af1534aa66f920e427af2ca3c47ee.jpg

Lovely.

Perhaps a built driveline and full noise launch might get a 300rwkw Falcon down to a low 1.6, high 1.5 60' - but if we're talking about that sort of mods, they're generally more than 300rwkw so not very comparable.

Again, feel free to share time slips.

Okay just because I’m bored in a meeting I’ll play the game with just my own direct customers that I found back through photos .... you know because been there done that, what would I know .... 🤣

 

We’ve been playing the “ What MPH does your dyno sheet trap” for over a decade on the XR6T platform and I’m being generous with the above post statement as there was some very staunch members who would kick you every which way to Sunday if you had a 400rwkw car that couldn’t trap 127mph minimum. Remember your fastest run typically will generate the days lowest MPH but as a general my above post statement is true if you actually have those RWKW numbers ;)

Brilliant post - thanks! Haha love those sorts of meetings (sometimes).

 

Very interesting seeing those slips and how the cars perform - especially the 11.29 @ 128.75 - the 60' was terrible @ 2.002 yet the MPH is getting up there! I wouldn't be surprised if that's a 10 second et if he can get that 60' down to a 1.7**

That 10.88 must have struggled to get moving as well - that MPH should be a LOW 10!

I know it's a different beast altogether, but there's a 2010 GT that runs low (10.3) to mid (10.6) 10's @ 128-130MPH at my track. So I'm surprised to see that the 10.88 above wasn't much lower! Guess traction might have been an issue?

 

Found my fastest slip from 17th Jan 2021 - unfortunately it's faded so hard to see and doesn't photograph very well but it reads:

(if in doubt - time is here..... NSDW quals - car 043)

 

60'...1.755

330'...4.884

1/8...7.445

MPH...96.73

1000...9.653

1/4...11.518

MPH...121.31

 

Most of my passes regardless of an 11.5 or a 12.2 - all trap around the 120-121MPH range. I've got a couple of dozen of them over the whole season.

 

I'm pretty confident that the 346.8rwkw that she pulled on the dyno was accurate. She did 5 or more full pulls (fairly back to back too) on the dyno and each time was around the same power - maybe a 1-2rwkw in it. My rear tyres were shredded by the time we were done - was on a roller dyno - not hub.
