looks pretty good but where does the vacuume come from to power the break booster, auto trans shifts, vacuum switches?? other than that i cant see a problem with it, and all those could be added in usind a drill, thread tappers and some experience and knowlege
They are more designed for highly modified turbo motors and you will not see much gain or any on an NA plus you would have the hassle of moving the battery to somewhere else. plus working out all the hoses that run in and out of the intake (water is piped through the plenum too). I've looked into it and its a big headache to say the least. But on a highly modified motor would be worth the effort plus they look great. The stock plenum goes well until you start really leaning on the motor and asking for 300+rwkw. Its up to you but there are costs and epa to worry about.
i think i'll stay with standard for now but upgrade the plenum later. its not an essential item to get the motor built and in the car. i'm curious as to where rb26dett got his from, how much and how hard to install?
