Cutting out boot floor ?
 

What are the reasons for cutting the boot floor out and putting a flat floor in?

Think to smooth the underside of the car (less drag) and fit a diffusher to suck car downwards (more grip) just a guess but all the top drag/time attack cars have them.

Not for weight then? Wouldent the exhaust muck the air flow up?

Think I will leave this to the experts now, all the top cars use a lot of carbon fibre to save weight, I will also be interested to hear the comments on this.:ok:

And alot of the big cars use side exit exhausts with the big diffusers

Not much of a weight save then?

What are you going to do fuel tank wise ?

Not sure yet, going to use the car at santapod and track days and need to drive it there from Eastbourne

This i post few months ago on SN

In my view is pointless fit on some cars,great addons,but too expensive if you want go carbon route.But you will need also get your car get little bit lower,because when car is lower then this flat floor create better downforce

You must know how it works and probably will be best test this in Aero Tunnel(£500 per hour), technically i would do this on mine,but practically will is not for me,due i don't want put something which i never use(i'm not professionally racing or i'm not preparing my car for racing/TA)

What times are you looking for at the pod ?

I was running 11.4's @ 128mph with 450bhp with just sound deadening out

Do you really want to go that far for a road car

Anger. think i need some tips from you, my best time is 12.4 , really need to get into the 11s

You should come up to one of the SDS rounds with us mate

Hi Anger , maybe you can pm me a few dates , info. Thanks

As the last one was a wash out, there planning on adding another round, as soon as this is sorted and i know when my car will be finished i'll pm you mate

Thanks Anger , dont forget

i cut my boot floor out for weight, there are eaiser things to remove/ do for weight reduction

Hi Jaffa what are those?

Do you guys who drag race use shift lights?

Nope and dont use lauch control

So launch control is the key then? Got it but can't get the hang of it

Sorry you don't use it. Take the 11.4 was in your ra? Was it stripped out?

whats your 60ft times?

Yep RA and was just the soudening and after market seats

0-60ft 1.54 and normally about 1.6 at the worst

On P2 we are cutting out rear floor pan next week.
Removing fuel tank and floor section and having it alley plated to include 30 Ltr fuel cell, twin swirl pots, fuel pumps & braided lines.
We are having diffuser made at same time will be attached to underside.

60ft times on the 3 runs were aroung the 2 sec mark
1st run 1.8 60ft 1/4 mile 12.6 105 mph
2nd run 2.2 60ft 1/4 mile 13.1 118.5 mph
3rd run 2.0 60ft 1/4 mile 12.4 112 mph

Should be about 1.6 on an RA mate

are you spinning up on the line or bogging down? 2.0 60ft seems a bit high

Had the dccd fully open and the back wheels were spinning so locked it and started to bog down, need more practice and some helpful tips lol

More revs... 5500 revs and lift a little till moving and then side step the rest

Launch Control is only beneficial when it mapped to launch and many aren't.

Optimum set up for most of the big fish in the Scooby world is 5000 - 5500 rpm at 0.8 boost. That is the set up for the quickest 0 - 60 ft times in general.

Triple plates are really hard to use.


Did anyone see Mikee Singhs launch at The Pod on Sunday afternoon ?
That was one of those best launches I've ever seen. The thing just took off.

Mikee did a 1.5174 60ft time with a 9.66 @144 thats on a 2.1 on a gt30 very impressive!!

No launch control with Mikee ;)
