whats the fastest 1/4 and fastest top speed ?
Turbo Mini Forums

may have had the fastest 1/4 a long time ago ! my black mini did 116 mph checked with 'datatron ' timing system , used in feature of 'fast car' (before it became 'body kit and neon car') wait for it ................ oct 95 !
really i just want a 'title' to put next to my name on this site !!!

116mph fucking hell.
13.62 @ 104 is the quickest we`ve seen

Everyone knows that instructions only have to be read if the thing doesn't work....

i remember running in turbo class at pod at the second showndown i think you won with 13.99 on slicks .might be wrong but now the class in road tyres and down to 13.77 .

Everyone knows that instructions only have to be read if the thing doesn't work....

That's a new one!

whats new??

Everyone knows that instructions only have to be read if the thing doesn't work....

I know SG knows his stuff but i do find a 116mph terminal speed hard to believe, not saying in any way it was'nt what the timing equipment said but wonder weather it was an official quater mile.

Or are we talking just top end speed?

116 mph was not the 1/4 trap speed but top speed - flat out run at bruntingthorpe proving ground at 8000 plus 3.9 diff hoping it didn't let go !i only managed 15.1 1/4 at the same test. Paul Whiffin was there too (106 mph ) my best was13.901 was 99mph at york

Not wanting to sound like a show off...BUT!!

I did run a 3.1FD on 10's with 150ish bhp turbo lump, that flew but i don't know the top speed as the speedo was straight out of an allagro vandan plas!..hmm nice smiths guages!!

But i have a very accurate digital mountain bike speedo on my car at present and at 7400rpm on a 3.44 1.1 drops and 10's it reads a tad over 120mph..But like SG you do get this "is it going to genade" feeling

But unoffical!!

I think "mini of williams" might have something to say about that one with his high final drive and oodles of poke.

Thanks "Jon"

at last some thing my car might be good at!
Well I don't have any thing that's official, how ever I have before hit my rev limiter in top gear which was set at a low 6,500 rpm, Running (here we got jon), a 2.9 diff.

I really don't mean to sound boastful, Just proud, but I wouldn't have backed off as it was still pulling well, I thought I had set the limit higher.
I NO it would pull to at least 7,000 rpm, maybe some one could do the maths and tell me what speed that would be.

hmm ok then, 2.9 diff, 6,500k..,.

*goes looking for calculator....*

cant find it, but at a guess i would say that its fucking quick! lol!!

And on the 7th day........... God created turbochargers!

can you look harder LOL

Asuming ur running 165/70/10's and 1:1 drops and a 1:1 4th gear and a 2.95:1 FD you will be doing 19.3mph per 1000RPM, so 6500RPM will be 125.45mph

Edit : - thats 127.6 mph if your running an actual 2.9:1 FD

Work you speed out here:

http://juric.org/mopar/tools/topspeed.php

I am running 13inch wheels with a 2.91 diff, which works out at 133mph at 6500rpm.
But remember you lose top speed due to the lack aerodynamics on a mini!

125 sounds about right.

I believe my car will pull an easy 7000rpm with what ever diff i chuck at it as the set up is very stable with good top end power.

Fookin ell Matt, have we both had a bump on the head??!!

killer_chiller

what is your car like with a 2.95 diff and 13" wheels? That is the combination the one I am building is planned to have, the thinking being that the turbo motor should have enough torque to easily pull the longer gearing.

Matt uses 10" wheels with a 2.9 diff.

Hi Tom,

The main problem when you have tall gears is the initial start off in first combined with the lag of the turbo, so its does require a little more clutch to pull away fast in first. But other then that no complaints.
The best bit is second gear - its good for about 60mph, ideal if your racing a five speeder as most would have to change gear!
All the gears are long and pull well through the revs + you still get that classic turbo power surge!
I have found that due to all power you are upto 5000 - 6000rpm before you know it in forth - could probably do with a 2.7
If you are intrested in 0-60 times and 1/4 mile times then I wouldn't recommend a 2.9 on 13" wheels, maybee 10's would be better. I however prefer to have good crusing speed, with a good top end speed, as the modern cars will walk all over you without it. Also it makes the car more drivable, as covering any distance in a car the does 70mph at 5000rpm is a head ache.

(If you are looking for a killer take off and want to kill your gear box + smoke your tires, keep reving the car up until the dump valve is whosshing, then in second gear slip the clutch to get the car moving then dump it! I take no responsibility for broken parts! - (neck mainly))

Thinking about the diff ratio - i think 2.96 is the correct ratio - but prob wrong!

Sorry to be a spam poster, but I was always of the understanding that turbos suit longer gears where as n/asp engines need close ratio?
But I assume you can over gear the engine?

trouble with having long gears is that you go off boost changing between them if your not careful...

all depends on what your using it for, mines track/sprints so needs to be short

I run 10's wheels with a 3.44 FD, I have a longer first gear than most (2.31:1) Some people have told me that I would have problems getting off the line, as I would need to slip the clutch lots. If anyone saw me at avonpark this year they could tell you that this is not the case. My next gearbox will have an even longer 1st. If I can change my final drive I would, but as I'm running an LSD, there is noone who currently makes a CWP for LSD's smaller than 3.44.

I'm aslo thinking of runing 0.958:1 drop gears. I'll keep to posted

Now you lot will probably think I am weird when I say this.....but......I LIKE TURBO LAG!!!

I like turbo lag mainly because of the great 'push in the back' feeling you get when it does come on boost again. Turbo lag and off boost between gears is fine by me, its not a track car as I already have one of those with much time and money invested in it, it is a FUN car!
My dad has an Audi ur quattro and the turbo lag and then boost in that is fantastic, sure the modern subarus and such are fast as well, but they don't give you the same big PUSH sensation as the old quattros/cossies etc do. I had a Subaru Legacy turbo for a bit before the fuel and tyres crippled my finances, and that was superb, nothing, nothing, nothing, nothing, read paper, scratch arse, have a sandwich, then all of a sudden whhhooossshhh!!! Heh heh heh!!!

LOL turbo lag is ok until you try and race a car with very little! then it's a real pain :(

cheers for the calcs, yes that quite fast I'm happy with that.

Yes I'm running normal 1-1 ratio drops and phil is right with the rest

Probably jon! lol:)

Often hanging onto lets say 3rd gear a little longer will bring the revs nicely into the powerband or boost as we call it for when you hit 4th, also a bootfull of the loud pedal between gear changes hepls to keep cranks rotating and turbos spinning.

Similar applies to going up and down those gear ratios.

Obviously a close ratio bow helps! Even my old bog standard MG Mutro turbo when driven with "a bit of zest" had no major lag problems.

Easy!
