I think Kristians ran an auto box that he said he thought was worth a chunk of time and is nos\'d from recollection? he\'s sticking a 20B in it now isnt he?

EDIT: just read your other post Carl, tubed and 20B\'d.

[20B_boy]

Just checked FF\'s, few extracts from the write up when it was 13B full body still:

395kw from a MazSport 13B with 2mm Mazda steel seals
Modified Ford C4 3-spd auto box running
Aussie BTR 4.8:1 diff
Turbonetics T76 bb making 1.7bar off the line by using the trans brake and NOS
1270kg with driver.


"The car ran 12.2 with a manual but, as soon as the auto went in, times dropped by more than a full second to 11.1. Then, on the same night, the car ran a 10.3 as Kristian got used to its feel."

You reckon he was happy with his nights work?!

Parting shot in the article:

"it would be nice to get under 9.5" - guess he wants 8\' now with the 20B

Please excuse my ignorance...I take it that these are special Racing auto boxes? electronically/computer actuated manual boxes, not the old fashioned auto boxes full of torque converters etc which sapped loads of power and always gave slower times than manual boxes.
:confused:

[Carl]

Just a small note,Kristians car did not use Mazda steel seals.
And subsequent to that article ran the low 9\'s.

These are the old torque converter type of box that sapps a load of power.No ECU management.

I think that makes my point, this is no street car!

Carl
Your interpritation of a road car is somewhat different to mine, sure you can up the drive train which I think you will agree is the main difference between a 12 sec car and a 10 sec car dont matter how much power you have it aint no good unless you can transfer it to the tarmac
:cool . But, by doing that [trans/diff mods] it becomes an undrivable car [as in popping out for a Sunday spin ect.] sure you can drive it on the road AND get an MOT but that is not exactly making it a \'street\' car is it?

As stated earlier in this thread it would be interesting to see one of these 8-9sec cars run those sort of times in the UK [I recon you would see 1/2sec added to thier best times].

My new set up is more about upping the power with safety and long engine life than making fast 1/4\'s.............. the old engine well that will be a different story:D

I presume it was in on Ceramics then Carl?

I was just parrott-ing the FFs article, says Mazda 2mm steel I think.

[Carl]

Having spoken to kristain about his car it was pretty dirveable,and used regularly on the road.
Is Geffs a daily driver then?Or does it spend periods of time parked up?

The seals were steel but not Mazda.

Seems to me we will have to dissagree, there is no point in my contributing to this thread any more, you cant even agree that these Aus / US cars that run such \'electrifing\' times are in all but name out and out drag cars.

It would be nice to see other UK rotaries running 10\'s [got any cars up for it yet?] or less but as stated earlier they wont be \'street\' cars my idear of them anyway:rolleyes:

[Norton]

ermm, yes, time to agree to disagree.

I expect that there will be a few UK rotors into the 10 sec bracket during the next year or two, the competition seems to be hotting up thanks in no small part to \'Rotorstock\'.
What i want to know is who is going to be the first to build a proper rotary engined \'funny car\' in the UK (i assume thats what the US 6 & 7 sec cars are; one piece bodied cars that hinge up for access to reveal a \'space frame\' chassis?). Anyone got a few hundred thousand pounds that they dont know what to do with?

edit: or are they? im begining to suspect that the US cars may be very like funny cars but with opening doors? or are the door lines just painted on?
:confused:

2nd edit: Ive found the regs for the US Pro rear wheel drive class. Must have two functional doors, driver must be positioned to left or right of centreline (so not quite a \'funny car\').
2 rotor min 908kg / 3 rotor min 999kg / 4 rotor prohibited (boo!) Methanol, Nitrous, supercharger or turbo (max 91.5mm). Any transmission (electronic/hydraulic/auto).

I drove it pretty much every day until I got the mini - used to drive it a mile to and from work every day - low boost of course! :rollin

Only reason its been parked up recently are cause a) it needs new tyres!! (not me honest), b) there isnt room for it at the garage with my FD (and latterly my mini) and andys beemer laid up when on average there are probably 10 others cars in being worked on from day to day - and c) i\'m parking the GT4 on the lawn at home as it is!

Mini will be gone next week hence red car is back from its holidays at Max\'s...will be \'home\' again soon, may with some new bits too :bandit  

Guys, to me a daily driver or street car is whatever u deem as such - as far as drag cars go, I think transmission is the key difference for me, mainly cause I hate autos so much and can only see the justification for having one if its a specific setup for the quarter! Obviously stuff like tubing and tubbs are more clear cut and that stuff doesnt interest me personally, I want a car that I can race at the strip or track and still drive for fun during the week on the way to work and through the twisties on the sunday - even if it is compromised in most areas by making it so.

Me, I would take the red car any where over any other car I have access to, even if it were long distance - its just too much fun to refuse. The only time I would take the birds car or the GT4 over the red car would be if I needed to carry more than a solitary passenger - or my other half was having a strop about the red car \'because its too fast and its noisey\'.

All up - who cares, if 10s dont cut the mustard compared to other world wide \'street cars\' then lets aim for a 9-some thing this year with one :p

[Carl]

That\'s great Rich.
I guess the new race gearbox should shave some time.
The only criteria I can see for a street car is that it is used on the street,Geffs fits that bill as do many other cars.Whatever the gearbox is being used doesn\'t make it a non street car.If it were the case then I guess we would have to exclude any gearbox upgrade.
I am not trying to take anything away from the achievements over here,on the contrary,but I was merely saying that due to the fact that we are behind other street cars in the world of rotaries we cannot sit around and make out that there is no further to go in improving what has been accomplished.
Looking forward to Geff or anyone else producing a 9 now.Let\'s keep that ball rolling!

I meant specifically stuff like the G-Force, Jerrico\'s etc - the ones with all those handles un **** and 6K converters!:rollin Thats hardcore drag!

The box we will have will still be an FD case with a convention H-pattern which is shifted by hand - hopefully just a bit hardier so we dont need 5 of them a season Main reason being so its useable in different applications (and cars) with different rear ends.

One of you guys with an old rotor should be able to stick a decent motor in it, a rear end and get close to 9s in May, dont u think Carl? :cool

I wish someone would, modern cars are much heavier than the old stuff due to the strict safety rules.

Multilink rear suspension doesn\'t hook up as well as a solid rear axle either
