it is.. different car though

 

bit confusing, but I think I get it. Marks car with Steve D driving.

Very well done on winning SSO

 

Yep, thats me, but using Mark Aigin's STi5 2.33 Lateral Performance car, which was simply awesome to drive

 

Ta

 

Do you know what your 60ft was on your quickest run?

 

5 runs i had

1 1.781 10.93 132 (1st EVER drive of the car)
2 1.873 11.08 132
3 2.099 11.27 131 (1/4 final)
4 1.899 10.93 132 (Semi final)
5 1.884 10.94 132 (Final)

I pretty sure i can get them down to low 1.7's with practice, bearing in mind i had never driven the car before run no 1.

 

Even more impressive then! Your first launch in the car was the quickest.

Do you know the spec on the car which did the 1.6sec 60ft?

 

cheers si, didn't do too bad yourself. 12.37 was better than 12.59 from last year. was really chuffed at going from 12.59 to 11.69 this year. alot work gone into the car and it seems to have paid off. are you coming over to enniskillen by any chance?

 

just as a matter of interest steve what power and torque is marks car running. between 550 and 600 i would assume.

cheers

big sinky

 

Bruntingthorpe is the same length as Elvington, but at Elvington the Topspeed is taken at 1.25 miles at Brunters as late as you can brake. At 200mph you are doing 100m a sec so it makes little difference maybe 1 or 2 extra seconds on the Throttle.
Rod

 

Bruntingthorpe maybe the same length, but at Elvington the drag seems to start about 3/4 of a mile up the runway...

Steven, I reckon that those pigs are starting to flock you know

 

Just checked, and Bruntingthorpe has a 2 mile straight. I don't think there's a 3/4 mils run off at Elvington, it certainly doesn't feel like it at 190mph

Mark.

 

IIRC there's 1/2 a mile of run out after the 1.25 mile timing area, the main runway is 1.92 miles long according to the website

 

Indeed & there is about 2000 Pauxhall's parked at the end to aim for

 

why do you need 600+ bhp to hit over 200mph?

the F40 broke it with 430bhp, the xj220 was in the low 500s and it hit 217.5.

I appreciate their aerodynamics are fer better, but without comparing the two side by side and with equations, how can someone so easily say it can't be done without a certain power level?

From what mark tells me the car was still pulling strong, and he was also driving into a head wind with the nasty spoiler in place.

 

thanks to all who organised the day,it was a fantastic day with lots of very fast cars running. still can't believe my little integrale got into the eliminator. hope to see some of you soon at TOTB

regards John Southcote

 

The Straight at Brunters is 1.7 miles long the remainder is now a car Park. Elvington is also 1.7miles long.
Rod

 

Cheers for the run against you.. silver scoob..

I was waiting for you to go after the light.. you waited for me..

David

 

My rear diff output shaft from Sunday.
Snapped clean off where it enters the propshaft !



Snap !


Further cracks


In the last pic, the lines you can see are actually cracks in the shaft a few mm's deep.

Andy

 

Not at Elvington they didnt or Brunters
Believe me you will require 650+ bhp in a Scoob at Brunters or Elvington its a very short straight. even a Yellowbird Porsche only reached 197 there . The 223mph Ultima managed 204mph & the Mclaren f1 did 211.
Proof is in the pudding. The Norris EVO did 200.7 with 730bhp, the Corrolla did 200.4 with 650 & mine managed 201.8 with circa 700.

 

****.

Whats your plans with that then andy?

 

Weld it

nah, just fit another one and see how long it lasts, these type of failures tend to be load*time related, I may get reasonable life out another previously unstressed shaft.

Wanted - drop gear (the one that the propshaft plugs into) from any 5 speed JDM scoob 93-05

Andy

 

Failure looks just like pauls driveshaft did, apart from the cracks..

howard @ hdc subaru
or anyone @ the clinic
phill venn (sp) @ Barretts
David @ API

I also believe mark uses uprated drop gears, unsure if the shaft is any stronger though???

David

 

Cheers David, Marks drop gears were supplied with his 'special' centre diff, not sure if they would fit a std or DCCD centre.

Andy

 

Ahh..

Stuff that then, that cost more than my car

David

 

Chris, I was talking about Elvington where the runway is 1.92 miles long

Andy, and some more. As David said just like Paul's driveshaft (but with cracks) one wonders if you could get a shaft made without the spiral machining marks, they certainly look like they're adding stress concentration points...

 

Neil (Bigsinky), i believe the Lateral Performance car ran 560ish bhp on the rollers the day before at Scoobyclinic, no torque plot was done.

Andy,

Elvington uses the short runway for the drag and top speed runs, and you also start a fair way up the runway.

Main runway is the 2 miler

 

The car is running standard internals.
TDO5 turbo by OMA (1.4 / 1.5 bar)
All the usual & necessary bolt-on parts.
Mapped by Michael White.
No weight reduction and running Dunlop SP7000 road tyres (215/45 r17)

Suppose a six speed is the next sensible option. Just got to find and pay for one!

Regards,

Warren

 

hmmm.

Andy,

dare I say it, but perhaps a new one is the best thing to buy? Then polish out those machining marks and shot peen it?

rear tyres grip quite well then! looks like it could have been worse

Paul

 

It was worse ! At first it didn't look like a big problem, just a driveshaft gaiter gone ?




Then I thought ? how did that fail all the way round at once ?

Does this diff look just a bit lop sided to you ??



The O/S shaft is sitting 30mm higher than the N/S shaft, the whole cradle is twisted.



The torque appears to have twisted the diff in the frame, far enough to chop the gaiter off against the top of the mounting, then sprung part way back !
