Not my point. I think Kmud thinks Leatherman is running 3.9's with a manual box???
Mistaken identity mate, I know about Leatherman's slushbox. Not sure on his diff other than he says it's whining!(What a weapon though, stock 5.7 with baby 216 cam, 4L slushy and 3.91's - talk about minimal!)

4L60E four speed auto gearbox (In Leathermans Car) has a fourth ratio of .696
If he can hit 180 with that I'll be very impressed.Edited by Xpuffin on Monday 11th August 18:48

It's true we could 
If that was organized and an appropreiate laptop was onsite to retrieve run data could we have leader boards for 0-60 and 0-100 times etc?
this would show the true difference between na and fi If that was organized and an appropreiate laptop was onsite to retrieve run data could we have leader boards for 0-60 and 0-100 times etc?
as some cars will reach there vmax before the mile marker.
There is no way low powered NA cars are making significant gains over FI after 1/2 mile. Ignoring the odd fast FI car which is hobbled by the limiter (Pah 250) or crippled by torque slump (North of Watford) I think the s/c cars are making the gain in middle to end sectors.
The quicker N/A are in the 10.5 to 100 and 13 sec 1/4 order on this surface. Expecting FI on road tyres to achieve 7 or 8 to 100 and 11 second quarters is not realistic.
Nothing else I lined up against on the day thumped me off the line as badly as Leathermans auto LS1 CV8.

My ute engine revs to 7800 easily and makes power upto 7500 rpm - get your calculator out on that and see what you get with 3.9s......... plus it makes a genuine 585 bhp at the flywheel. So I reckon it could do 180 mph if my little Monaro with about 400 hp can do almost 166. But the proof is in the pudding, so I'll see if we can swap motors for next year as it would be really interesting to see if it could actually pull the numbers.Edited by Xpuffin on Monday 11th August 18:48

Whats the spec on the engine in the ute Leathermanjameshsv said:
Whats the spec on the engine in the ute Leatherman
A fair bit of stuff including 2" DF headers, BIG cam, RHS heads and a couple of other bits.Here's a snapshot of a 10.8 run in the ute back in 2008 - note the revs ;-) and the nice square trace for % Throttle!!!!
Also at the 1/4 I'd be at somewhere near 125 mph assuming a good launch, which is key to VMax for NA engines, so I'd have a bit of distance to pick up the remaining mph.
And even with this she was a pussy cat on the street thanks to the tune. A thirsty pussy admittedly!!!!

So assuming a 3/4 average speed of 150 mph (125 +180/2) that means time to run is 18 secs to the mile. Speed gain is 55mph using a gearing good for 212 mph limiter and only 600ish fly.Here's a snapshot of a 10.8 run in the ute back in 2008 - note the revs ;-) and the nice square trace for % Throttle!!!!

I can't see it. Gearbox ratios are wrong for the mile at that power level.

The ute has 4.11's in it - perhaps that might help......... and you're working on 100% transfer of RPM to velocity figures that will not happen via a stall converter in an auto in my setup. She'll make 0.5 past light speed.... oh sorry wrong saying. No seriously I think she'd do it. The difference in power and performance between LBT (the ute's nickname) and the Monaro is staggering I can assure you.I can't see it. Gearbox ratios are wrong for the mile at that power level.
I think I've shared this picture before but you can see how lively she is in race mode with 1.41 60' times!!

I'm pretty sure you're Monaros running a lot more than 400 too based on your position in the rankings.Edited by TheLeatherman on Monday 11th August 20:56
Good luck though, like I said, I'd like to see it but the miles a whole new game over the quarter.

Mine only does 12.5 quarters so I wouldn't see which way you went off the line but my TS is 137 so whilst slower time wise I'm actually going faster. That's what you were seeing at TR with the big FI builds.Xpuffin said:

I totally agree it's a different kettle of fish, but I've done a bit of homework on a 1 mile run from standing start.Good luck though, like I said, I'd like to see it but the miles a whole new game over the quarter.
The Monaro is putting out a genuine 264 rwkw = 350 bhp at the wheels. That was what was on the dyno sheet from back in 2005 and she's never been on a dyno since. Again I think hard, but decent, launches for NA cars are crucial as it gives it chance to get up to speed.
If time permits we'll do the transplant. If not maybe Dougie could make an exception that I trailer it up there as that would be a lot simpler although aeros might affect it a bit. I'd love to run it against Gareth's 454!!!! I think he'll smoke me though with the grunt that thing will throw out!!!

That's a lovely thing to see but it's not going to get you to 180, just the mile quicker which actually means less time to accelerate.I think I've shared this picture before but you can see how lively she is in race mode with 1.41 60' times!!

If you've no lockup on the stall you're loosing power. I have a switchable one on Mental Betty and is a fair chunk when you are pushing on if I switch it off.
