Glad to see your coming Tino.

Reverse scoop.
Leave rear wing on. I would want some downwards force on the rear at high speed,
keeping the tyres well and truly stuck to the road.
Use the prova front bar.

Talk to Douglas about tyre and suspension setup T-dawg.

Gear Ratio Speed Calculator

http://members.iinet.net.au/~wearne/...ns%20Specs.pdf

Gear ratio speed calculator .. not sure how accurate!

Using that calculator,

0.756 6th Gear
3.9 final drive.
18" rims.
8500RPM

247km/h .. reckon you would get there pretty fast with 600 odd horses though

That is on US gearbox? AU has a shorter 6th? So could be even slower.

This may also help to know how much HP you need to achieve a given speed:

I am going to prep the car before the event for sure.. will also be getting a retune for more power and a few other things.

Gearbox is the issue might need to borrow a longer ratio box for the event..

i put it back together but have not remedied it.. Going to look at that. i.e weld up the pipes and put a joiner lower on a straight and have actual bolts linked to each pipe to stop blowing off.. bit of work to do still..

no not at this stage.. the ferrari 360 CS has a recorded time 0-1000m of 22sec and 240kph.

scoop will go and will also fit the prova front bar for a bit more downforce.. will also tape up the front end for better drag..

I'd go scoopless or reverse scoop if possible. Also try and get your run at the hottest part of the day so the air is thinnest to reduce your drag.

The gearbox is the limiting factor... The car has done 220kph to 400m with 575whp completely different setup to the 614whp setup. Was in the top (bouncing off redline) of 4th gear when crossing the line. So with another 1.5 gears i think i should be able to pull around 40-50kph more??

The gearbox is an 05 sti DCCD box with 3.9 ratio i think.

Thanks rich.. Hmm i think that it might be slightly inaccurate as i said before redline 4th gear 220kph to 400m...

i might have to go to RAC and do some testing..
