i know these are dopey newbie questions and they may or may not have been covered but i couldnt find anything that gave definate answers in other posts or google searches.
1. Are external wastegates legal? I have read and heard they are legal as long as there there's no venting into the atmosphere (basically its fine if its plumbed into exhaust).....but i have also read that they are illegal because they come under the same laws as a boost controller which can allow you to modify the performance of the car without having it tuned so it still follows the e.p.a 'emission' laws. basically im just wondering if anyone knows for sure whether they can be legal if they are plumbed in without an illegal screamer pipe or if there is just no way to have one, and considering i run straight lpg which puts out bugger all emissions anyway i dont really get why it would be illegal, which is why im curious.
2. Again i've read and heard its illegal to install a larger turbo on a car, and yet i have seen plenty of cars getting around with T04's or gt35-40's without any issues, and from what i could make of the vic roads website, bigger turbos arent smiled upon, but if it gets an engineers cert you should be pretty well right?
3. Cold air intake on turbos is beneficial? im not saying it is or it isnt, i know everyone here will say cold air= more dense=more power....BUT, my question is what difference would it make on a turbo when the o2 from a CAI would only get heated up after passing through the turbo only to be cooled again by a decent intercooler if your running one....so yeah the question is what benefit is there to be had by making an effort to get cold air to your turbo if its only going to be heated up again before it gets cooled yet again by your cooler.
Like i said i know these may have been asked before but i just cant seem to find any clear yes/no answers, so if there is anyone who knows any of these things for certain then your input would be much appreciated. thanks. josh
