Yeah, the whole car is made of glass, so you can drive them in sand with no problems bro. Try it sometime, go test the 4WD out on a beach! :oops: :lol:

Damn possums... nearly lost my front kit to one once.

Then there was the time my mate hit a penguin... poor thing had a stuffed hip and was in shock, had to be put down :(

havent really done that for a while let me get my gun license (wich i probably will never get to) haha and then well go cane a few,skin them and sell the furr hahahaha, and tp all the critics(and glass car bashers) love yuor work keep it up(sarcasistic tone)ring me when you need your dippers changed and ill stop shlonging yuor mum so she can come and powder your arses..................... sory had a random spat of negativity,any car is like glass if yuo dont treat it right,how many people buy scoobies,think the possum bourne(respect to the legend) or chris west and thrash them no wonder they snap and break,if you treat yuor toyota like rod millian.... it'l break to
drive it till it breaks, then upgrade it

engine vacuum as at its highest at idle. due to the fact thats the pistons moving up and down create a vacuum. and because the throttle butterfly is sealed, there is no atmospheric pressure entering. under wide open throttle there is 0 or very littlevacuum in the intake.

turbos force more air into the engine making lets say positive pressure. hence why when the throttle shuts all that pressure in the intake piping needs to be vented somewhere, ie through a bov.

sorta hard to explain. but some of you may get what im trying to say

Engine vacuum is actually at it's highest on over run,
ie, driving down a hill at 4000 rpm with the throttle fully closed.
