How do you get into motorsport?

[fpv_gtho]

thats pretty cheap for extractors, if its a good design (all the tubes ar equal length and look about as straight as you'd get them) then i'd go for it, thats where your gunna get the most power out of the exhaust

[SlickHolden]

I would love exstracketers on my mum cars


Catch you guys later

[fpv_gtho]

they can be good for about 10% more power, some designs will be 15-20% with a full exhaust

[Blue Supra]

oooo
ill get up to 100horses

[fpv_gtho]

haha, how much does the car weigh

[Blue Supra]

not much, prolly 1200kgs... (without me in it)
what do extractors actually do?

[fpv_gtho]

the way theyre designed, the flow of exhaust out of one port "extracts" the exhaust out of the next one, and so on and so forth...so they just suck the exhaust out a bit

[Blue Supra]

faster flow kinda thing?

[fpv_gtho]

yeah pretty much......the faster you can get the air and petrol in and get the exhaust out, the more power you'll have

[Blue Supra]

mmm, what do you rekin ill get out of a wider exhaust beside a better note?

[fpv_gtho]

well the exhaust can be less restrictive, but if you go too wide it can be a negative effect. you'll get a nicer note as the wider the exhaust, the more the exhaust is echo-ing, causing the sound, but theres LESS flow, so theres F all trying to PUSH the exhaust out....so you gotta find something thats not restrictive, but still is a bit so that theres that pressure pushing the exhaust out

[Blue Supra]

i asked the guy, he said no bigger then 2" or id lose power, this one will do a 2L engine so im happy with that if u go up to that later on.

[fpv_gtho]

that sounds about right.....i know for the XR6T, i dont know what its got standard, maybe only a 2.5 inch but APS fit a 3.5 inch and with the boost wound up to 9 psi, its about just right.....its that bit too free flowing on the stock 6 psi

[Blue Supra]

wind the boost up to 25 psi, lets get some REAL turbo kick then

[Colty]

Wouldnt 2 medium pipes be better than 1 big pipe?

OW 25psi, thats pushing it, LITERRALY!!! lol
