Eeek -those times are blistering -even the slowest!

What sort of power were the lower end of the field running?

Not sure about power, but the Class A car weighs around 470kgs.

If anyone doesn't know what the 'guessworks calculator' referred to earlier in the thread is (like me!), I've looked it up:

[jonspeed 1400 sprint]

Bill Richards, Brian Slark, Nick Swift etc. etc. and they are all wrong about output and performance on engines that thay not only run themselves but also supply to half the field.

I think not.

The times quoted are proven meet after meet.

Out of my league I`m afraid, I run 1400 cc, 36/31 race head, 1.5 rollers on a kent 296, 45dcoe, s/c roller drops, sccr box, x pin 3.44 dif and she will rev to 7200 in top. Lightweight shell 0-60 in about 3 years........so far.

I aint got 20k to throw at an engine/box from these guys but boy would I love to.

John

the 1/4 mile time in my old mini (at shakespeare last year) was 16.8 secs, standard shell with a roll cage fitted so it was quite heavy.

that was a 1330cc
morspeed stg 3 head
morspeed P3 trackday camshaft
HIF44 carb
straight cut drops
3.44 FD
the car was never set up on a dyno but i did go to the mini forums dyno day at smart performance last year and the car had about 70bhp at the wheels.

[John Clayton]

interesting -mine has 74bhp at the wheels (Flywheel bhp Estimated to be 100) so it will probably be similar performance

There is no where in a race tha 0-60 times are measured, so they can't be proved race after race. I think Migs and Se7ens are great cars, but they are built within the confines of the regulations. thus, they are the greatest minis within the regulations, but not the ultimate minis.

There is no proof that a Mig is as fast to 60 as stated and the numbers just don't stack up (BHP, weight, gear ratios).

[Sprocket]

There have been some Migs and sevens run the 1/4 mile at MITP, so the times are some where, but from memory, they weren't that impressive. The main reason is the power to weight ratio is still quite high for a Mig as it has all that extra tubing. If you have a heavy car, you need a lot of power. I ran 15.2 1/4s with 150hp 16v nitrous 1275. without the nitrous it was 16.2. That tallies up with Fast Carl's rule of thumb that you need an extra 50hp for every second you want to knock off your time with the same car.

How do you mean they are wrong.I cant speak for the others but slarks have done a lot of work on my mini and personally i think the power figures from his rr are conservative compard to whats thrown around this site.

With regard to 0-60 times, they run in car data capture which will provide the info and as I said, engine builders of this standard dont need to bull. Do you think they would risk business worth many thousands of pounds by making claims that their competitors can rubbish............

Whilst the 0-60 times mean very little in racing, winning the sprint to the first corner does, it can win or lose a race. You can bet that an awful lot of development goes into that initial sprint.

Miglias run 14.6 - 14.9 on the 1/4 mile, Ive seen them.
My car runs 13.0 on the 1/4 mile.
If my car cant reach 60mph in 4.5 seconds then a Miglia certainly cannot.

[John Clayton]

Paul, what sort of power, weight, top speedd, terminal velocity (on 1/4 mile) and 0-60 is your car?

Theres some details in his project thread.

I don't think any of the engine builder have or would make such claims, the claim is from the website associated with the racing series.

No Miglia has ever got to 60 in 4.5 seconds, the only place this has ever been claimed is on a website which is trying to promote these cars as the top class of mini racing. As I have said, Miglias are amazing cars, but they are built withing regulations, so they can never be the ultimate mini.

[dig-mini]

Mine does it 0-60 in around 5min 12sec with or with out the 2 kids and wife

[Paul Wiginton]

Paul, what sort of power, weight, top speedd, terminal velocity (on 1/4 mile) and 0-60 is your car?

155 Baldwin horse power, no idea of reality hp as his rr reads high, 400ish kg, 107mph on 1/4, 0-60 dont know, revs and gearing say around 110 - 115mph top speed is possible.
Obviously I concur with what Wil says on Miglias.
I would be very interested to know my 0-60 compared to the few 12 sec turbos, although my n/a is slightly slower on the 1/4, my 60ft time is quicker at 2.0 secs, therefore mine could be a quicker 0-60 or atleast very close indeed.
