Matt,

Ok - I knew you stuffed it but didnt realise how lol... gees that sucks ay.
Well, now you have bits and pieces... fix the thing and let us know how it goes.

You know what I am waiting for you to do though mate... get the darn thing down here for a engine dyno OR lets go on the 1/4 mile... we might even go with an N/A engine against the turbo twinky :D oooh theres the challenge lol

Cmon cmon cmon - get it fixed... I know you have nothing else to do at the moment!

When do you think realistically it will be finished though?
What about your race donk? When roughly will that be complete and ready to actually race?


I see your point about running lower boost though mate - the guy who bought mine wants it turned down... unfortunaltey the way I setup wastegate its pretty much 10psi MIN unless he does a couple of changes.

Also - you mentioned diff ratio's - I ended up with 3.765 in mine but really should have left the 3.44 (or even 3.2) as yes - the load up is so much better... with the 3.7 its very agressive when it hits boost... and very hard to control... (its still bad with 3.44 but better than 3.7)


Pete

A 12.63 from NIc's turbo 5 port not to bad i think, and Jimster with his silly Turbo Twinky doing a 13.0 with a terminal of 115mph :wink:

Nathan.


Pfft - Nics car weight in at something like 400kgs... 12.63 in 400kg car is good but we cant really compare... we have ours running 13s with full trim ;)

He''s done some wicked stuff but weight is definately against us comparing to Nics.

Pete


I don't think the times coming from the UK are at the level they should be yet. There is still lots of development happening getting Minis down the 1/4mile.

Key thing we need to look at for all these times:
1. Car HP
2. Car Weight
3. 1/4 Mile time with 60ft and trap speed.

From here we can get a good gauge of the performance an engine.

Take my car:
1. 200HP
2. 750kg
3. 2.1, 13.45 @ 105mph

Compare that with a 400kg car doing 12.63 and the car is nearly half the weight.

Most of the pics i've seen have cars with fibreglass panels, no bonnet, perspex windows etc for the really quick minis.

Hardly street trim or road legal.

eg:
Image

Best time by far performance wise now i think is Dennis (evolution) 1.4L K-Series, T28 @ 2BAR 11.9sec 1/4 120MPH, full steel body, street trim, with drag slicks. Driven to the strip 700km each way :shock:

That is seriously impressive.

Matt,

Jimster/MiniWilliams, where do these power figures come from? rolling road, engine dyno? they all read ridiculously high in the UK.

1/4mile doesn't lie but you must take into account the weight of the car and the tires used along with terminal speed.

Let's take Jimster as an example:
From his website:
"1980 mini, re-shelled, bulk head mod's for turbo, Miglia arches, painted Ferrari Fly yellow with back roof, laminated front screen, polycarbonate windows and front and rear screens. Curley Carbon Fibre Boot, doors, and boot floor, front end, cut and tub rear arches"

That car would weight max circa ~550kg probably less.

He's Claiming 255bhp (bhp= at the wheels? "brake hp") as on their rolling road. (25psi boost)

1/4 time is 13.0

no doubt it's making serious hp and IS a seriously fast mini, but you gotta compare apples to apples. It's a good 200Kg lighter than my car, i'm only claiming 200hp as on our dynodynamics (which is still not a 'real' figure i bet) and that's on 19psi.

So he ran 0.4sec faster with a 200kg weight advantage and more power. If his power figure is true then there should be much improvement available there (going off the information provided).

I vote we arrange a meetup at WSID with all the hot minis in Australia. It will sort out the men from the boys 8)

Who will be first into the 12's?

Mini-mad,,, although i do believe Jimsters car is "somewhat" light,,, i don`t believe it`s as light as you suggest,,, he`s fitted a full, multi-point roll cage into it, along with it still having passengers seat & belts & sterio etc ,,,, & all that fandangle computer guages & stuff,,, The cyl head on it`s own (for example) is heavier than a 5 port,,, then you have all the turbo & manifolding & intercooler & inlet manifiolding & all that extra weight of efi pumps & lift pumps & filters & swirl pot etc etc etc,,, as you well know all that stuff adds up

as much as it may "seem" like it`s not really a lot of ancillaries,,, mate it all adds up

Half the time people who have light-weighted their cars, well it`s all in an attempt to reduce the extra weight that the roll cage & extra ancillaries adds

& than there are the "Other" people who tend to enjoy "pretending" that their car is "SOOOOOO" light,,, well,,, put them on a proper scale & see,,, there is more "pub talk" in lots of this stuff than facts & they`re usually a lot heavier than stated.

I`ve taken big chunks of weight out of minis (my whole life) & i`ve weighed minis all along & i can tell you that once it`s all said & done,,, a mini with a "DECENT" roll cage (Not just a half , like hoop & 2x rear stays) i mean a "Real" cage like Jimsters & all the other odds & sods that go into a race mini make for a pretty heavy package,,, some stuff like carbo & titanium & alloy & whatever, often only barely make it back.

That is unless you totally strip the entire inside of the car of "Everything"... fit "Thin" lexan or perspex windows "Every where".., rip out all the inner rib cage of the car out,,, all sound deadening, all unwanted & un-needed brackets & tabs,,, drill all bolts,,,, fit super thin brackets to hold everything & use those same brackets to hold 2 or 3 items :-) etc etc etc crickey even with a carbon doot, complete front & a roof can take lots out of a car, alloy rear arms & alloy rear drums & alloy front calipers etc is all reducing weight yeah... & yeah all that lot is a big chunk but compared to fitting a dam big mulitpoint roll cage & a pile of turbo & injection stuff back in.... well , it`s suddenly not so light weight anymore is it?

But i won`t argue that Jims isn`t light,,, of course it is,,, one word---> ColinChapman :-)

I bet my 998cc gives you all a dam good run for your money :-)

& yes that may seem like a rather bold statement,,, Yes it is infact a trick statement,,, best you think before you say anything about that one :-)

Hi Matt,

I know your hairdrier version is on the fritz, but is there an N/A one in the making or made yet? I'm pretty sure you said you had one coming, but I can;t remember :oops:

Still keen to see how an N/A comes up in banana figures and very keen to see a 1/4mile time too.

No rush, just when you get to it. :wink:

Cheers

Aaron

Is it an a/a+ series 998? Is it out of a car or bike?

I mean this in good heart so please don’t take this the wrong way that I’m having a go at any one just think it should be said.

I think brushing that off because his car is light is well... not very fair. Look at it the other way the Mini has turned 50years old now. The A Series motor was designed well before that time and with lots of work Nic has got a Mini, with a Mini motor with a Mini 5 port head running 12 second 1/4mile i don’t think you can Pfft that off mate. :roll:

Jimster “I really need to learn to get my car off the line, 2.59 60ft time on my quickest run of 13.0 with a terminal of 115mph (held back by the limiter).” So I think there is some room for improvement :wink:

Well yes we do don’t we so with a mini motor that is 50+ year old design, with a more modern head (and obviously more not questioning his build) on it doing a 13 with a slow 60ft of 2.59 and we are trying to compare that to a 4E-FTE motor. It is a big deal running those sort of times as you know 0.4 is still a lot, so credit where credit is dew I think. :)

Nathan.

Let's not turn this into a 4EFTE vs A-Series debate. It is merely my time and information that i knew was correct for comparison.

Engine type is irrelevant in the scheme of things. 4EFTE, Twinky Head, KAD 16V, Elder 7-Port, 5-Port Iron Head, Turbo or N/A. There is no point trying to push for what is better than the other. You choose what you want and as long as you're happy that's all that matters. Someone will always have more power.

I don't believe the 4EFTE to be some holy grail of super engine. At the end of the day it's still 1330cc with a Turbo. Engine type, head etc just mean varying levels of efficiency and reliability depending on what you have.

No one is brushing anything off, if we're comparing times weight comes into it, no one is disputing the times being put out.

Take Greig's Nb race car, could be street registered, full trim, steel body, 5-Port N/A ~150HP 13.9 1/4mile. I'm sorry but "300HP" 16V Head + Turbo and more cc + lightweight panels with a 13.0 flat doesn't seem too impressive. Is it a quick time? a resounding YES. As you noted 2.65 60f/t means there is room for shitloads of improvement and the ET is massive, i would bet low 12's but compare that to a full steel body car with full roll cage (a 'proper' one), naturally aspirated 5-port.

Floss,,, it was a trick statement :-)

Image

well,,, it "IS" a 998cc :-)

The whole thing Only weighs 200kgs tho :-)

sorry,,, i just couldn`t resist

& yes there are plenty of N/A Bimmers happening all over the place ,,, i have an N/A 998 that we`re still playing with, developing cams & such,,, & i have a quite a few engines i`m building for customers.

Aarons is N/A on bike carbs & was at the melb mini 50th,,, i don`t think he`s had it on the dyno yet tho,,, still be a few things to sort out i`m sure

& Al has one running up here that is pretty srd-ish, but fairly low compression & is running std bimmer cams & has 74 at the wheels at the moment,,, obviously more to come from it tho as it`s just simply been bolted together & not much of a play has occured at all yet.

There are heaps of conversion kits out there & i`m sure you will see a whole heap of them come out of the wood work as time goes by,,, they don`t take half an hour to build & with cam development happening & lots of head work happening ,,, well,,, 50 years ago the mini was born,,, they`ve been crawling, walking, running, sprinting & now they`re flying,,,, the Twinkys are barely on their feet yet.

I`ll say it again (as i`ve said it many times before) """Rome wasn`t built in a day"""

minimad,,, you have a dam good little car there,,, no one is disputing that,,, i`d like to believe that we can make a package come "somewhere" close to having the same sort of quality as yours,,, i`d be a happy chappy :-) cheers mate, maybe see you on the strip soon :-)

Yeah but hang on - 1/4 mile is driven by HP, grip and weight... sorry no-one can argue against that surely.

Take my 1500kg XR8 pulling 13.5 down the 1/4 mile. Thats with over 250hp at the rear wheels. If I used perpex and not glass and fibreglass or carbon or thin stuff and got it to a ton it would go MUCH faster... thats a given...

My mate has a 1.6ltr B16A runnning 34psi boost. Its a CRX with lightweight everything perspex, la la la and it does 9's down the 1/4 mile day in day out. Won australias fastest front wheel drive a couple years back too...
Yeah its 1.6 turbo with big boost but whack the same motor in a full trim CRX and good luck even getting close.

Regardless - my pfft against Nics car wasnt against his car or times. Its built to do a certain purpose. Cars that are street rego'd pulling 13s (minis I mean) are damn quick... ala Griegs Mini or GRs

I suggest we all get this really sorted - give it a whole year or even 18months notice. We setup a AUS wide invite to WSID (Home of Australian Drag Racing) and like Josh said 'sort the men from the boys' :)

1000hp and a crappy 1/4 mile or race track time is useless. (Take my other mates project, 350 Chev 5.7 Litre Twin Turbo donk in the back of a 911 porsche... sounds awesome looks awesome but nail it or try to drag and your gooone, makes doing burnouts a breeze but even Marlene's 18sec 1/4 mile would beat it until he sorts traction out lol

Josh - organise it and ill get a mini ready for it :) Give me 12months minimum to convince the Minister of Finance I need to build it though...
Yes, it will be A-series bottom end and some special stuff up top :D

Pete

Oh & Pete, sorry i forgot to answer your question about my race twinkys,,, they will be ready when they`re ready, i`ve no time frame set for them at all...

For starters,,, If you can imagine the amount of cars i`m building at the moment, both for customers & myself,,, well,,, the customers cars need to happen earlier than any of mine of course,,, & then we have the Monaco fastback to complete,,, the R1 powered hillclimb special,,, 2x cooper "S"s to restore,,,, the V8 speedway mini (& it`s gaggle of 3x other speedway minis at the moment, but attempting to eventually creat 10x speedway minis so we can have our own mini race) ,,, My Black sports sedan mini,,,, My mate (Stew`s) 6-speed Arden cross-flow sports sedan,,,, My other mate (Archie)`s stn wagon restoration,,, & another mates (Gaz`s) purple mini sports sedan,,,, All the other Twinky development we are in the middle of,,, all the parts we`re having made in China,,, My house renos with lifting it up & building underneath & a rear deck to build, (one day i will be rid of the temporary plumbing & electricity) My 3x boxer dogs,,, my girlfriend has me once or twice a week (if she`s lucky) :-) ,,, etc etc etc

so,,, as for the race twinkys---> at the moment i have 2x Sth African cranks,,, 3x 16v cyl heads, a pile of engine blocks & pistons & other related parts collected along the way specifically for these 3 engines,,,, i`m chasing some special con rods for them all & i`m in need of a whole pile of other goodies for all the other cars,,, etc etc etc

& Now i`ve just bought my dad`s Mini Marcos GT,,,, & looking to buy his 48 model Packard as well,,, we also have a woody wagon & an Austin wagon we need to restore one day too

Now,,,, that is all in the middle of doing the normal daily customer service work, tune ups, brakes, engine swaps etc Just so i can make a living along the way,,, we also have 2x panel beater/spray painters i need to keep in toe , doing rust repairs, paint & panel jobs (when ever they god dam feel like it) :-(

soooooo,,, i`m hoping that my race twinky donks will be done in amongst all that lot , somewhere along the way

:-)

& somewhere inbetween all that , i need to actually have some sort of life, maybe a surf every now & then :-)

A $30 million lotto win would be cool,,, cause i`d have the race Twinkys sorted & ready in a couple of months :-)

I asked him and this is how much it weighs:
"my car is 650kgs (without fuel but with me in it) a few weeks ago"

I havn't seen the man but i'll go off the average bloke is ~70kg. So that takes it to ~580kg + 30kg for fuel (probably not running with 30L of fuel at drags) = 610kg. That's a good 150kg on my car. A considerable weight saving in a car that is already light (20% lighter).

I think the car is great, has a lot of initial problems to sort out (like us all) and will be for some time (just like me) and i can't wait to see it's true potential realised, but you can't discount the weight advantage when comparing with street registered times in aussie cars.

yeah , you`re right,,, & in all comments

& i "Think" he`s claimed 255 at the engine,,, seems its the way the pohms do their calcs from a run down measuring losses (or attempting to guestimate) so they equate the power back to the engine that way

& yes,,, 150-ish kgs is a good chunk,,, throw the 2 kids out (or that big phat mate of yours) & you`re instantly going to accelerate quicker

I`m a bit warey to suggest that there`s a lot more to do with traction , & the abiltiy of the driver to grab it,,,& use it via correct gear change points within the power curves etc etc etc

there`s a big chunk of driver thrown into the mix

we did a back to back test (or rather a number of them) with regards to different drivers doing the same "bess stop to busstop" stop-watch times & the variations were huge between the different drivers in thesame car

so as much as i totally agree with what you`re basically calling "Development" of the cars for use in 1/4 mile drags (totally different set up for circuit use) ,,, , yes very true,,,, there is also a big chunk to come with the "development" of the drivers abiltiy to control traction & revs & gear change points etc,,, as is the same for circuit racing

Obviously i`d be the very best in the world at all forms of mini racing :-)




Just kidding

:-)

How come in this entire conversation I have not seen one reference to torque-power/vs rpm/weight.

Everybody keeps banginng on about power/weight but doesnt it depend where and how its delivered.

So if its providing 80 percent of its x torque/power at 3000 rpm going to trump something providing 20 percent of 1.5x torque/power at 3000rpm given similar weights.
