getting ready for drag racing

[Rupewrecht]

windows - not sure on that one - you could always cable tie the gears/arms in place

[QuicKSilveR]

Hahhahahah - I'm not a fan of removing everything. I'll be run with my stereo install, jack, tools and spare wheel.

My aircon and air suspension is gone now but the engine weighs a little more than the old.

[twilightprotege]

i'm mainly doing the removnig everything just to see how much weight i can remove from the car...weight under stock - ie my rear strut brace was not counted in the weight reduction figures.

the by product of it is quicker 1/4 mile

[QuicKSilveR]

What power you making now.

175hp at wheels would make for a quick car. We would be good competition

[twilightprotege]

123.7whp - still have plenty of room to grow however.

150whp should be pretty easy to get too from here. just getting a piggyback ecu would get me pretty damn close (as my mods really really need an ecu to take advantage of them). from 150 up is where it'll get difficult, but i'll get there one day i hope.

You can't alter the weight transfer unless you change acceleration, cg height or wheelbase... you can cange the rate of mass transfer and control pitch attitudes by stiffening/softening the suspensions, but weight transfer is one of those immutable things.

Twilight how much of the weight that remains can be shifted forwards in the car? Probably not much, but it might help if you sit really close to the steering wheel! :wink:

Well that then! I knew what i meant

[ezin]

Some fair ideas there! I went the opposite and made sure everything from the factory floor was in the car + all the fluids at full.

I also had in the car:
*Melways
*120cd's in folder
*40kg sub & amp
*skateboard
*fold out chair
*Ralph mags (2)
*torch
*camera
*first aid kit
*6 pack of beer

I did this so it would be a realistic time of what the car would get everyday of the week, which was 16.2, so i was happy with that.

Best of luck with the drags! Hope u get the sp20's into the low 15 bracket

[preeman80]

[twilightprotege]

yeah i'm going to sit slightly closer to the front...but i cant think of anything else that i can move forward....

i'll be taking the side skirts off tonight. will weigh them ofcourse


any comments on the tyre pressures i posted earlier? (46psi at the back, 15psi at the front)

[Cosmo Dude]

Move the radiator surge tank out of the way so you can move the battery forward, it's one of your biggest single relocatable mass objects.

[twilightprotege]

hmm yeah....will look into that

[twilightprotege]

ok, side skirts, rear wing and rear window wiper and motor removed.

up to 75.5kg removed

that's the equiv of an additional 10whp or more depending on which internet formula you use...

[Nate]

and motor removed.

i hope thats the wiper motor ... you will run a slow 1/4 mile without hte other one

[twilightprotege]

LOL....yes nate :P

are you removing anything for this saturday?

[ABC]

seat belts? except the drivers of course :wink:

[twilightprotege]

rear seatbelts are gone (damn they are heavy suckers. a few kg i think from memory). forgot about the passenger side seatbelt. will have to see if anyone is coming out racing with me.

[geetee]

are you allowed to race naked? ops:
apart from a helmet of course :lol:

make sure the 3 B`s are empty.......


bladder, bowels and bollocks :lol:

[twilightprotege]

LOL!!!!

unfortunately no, must be covered head to toe....still can run free-balling to save weight

[DrSilver]

dude, your car must look like ****! :lol:
