what's your opinions on dynomax exhaust and spiral max turbo air twister? Will they really increase my hp?
check out www.spriralmax.com -- is this for real? +35hp from that? >>

think about it logically. do you really think reducing the turbulence of the air entering the intake manifold is going to give 35 hp? the answer is odviously no. stick with a good filter instead of investing in that crap.

erm ok heres how i see it, you know as a kid u musta saw one of these. two 2 liter bottens top to top with one full of water and when u flip it over the water transfers making a tornado if u shake it in a circular motion? ok if u do know. if you dont shake the bottle the water just goes glug glug glug so slow. but as soon as the tornado starts the water speeds down to the other bottle. thats what that spiral is doing. i dont know about the 35hp but i know it helps MPG. my friend has one for his astro van he likes it said he has more power and better MPG. i dont know.

I had one of these in my INJEN intake for my 5sfe motor and I did notice a difference... it wasn't a 35hp difference but there was a good gain

Yeah, what they said...

It does actually work and gives small increases of a bout 5-10 kilowatts so thats like 7-14hp I think (sorry not real good with the conversions) this is of course on a set up with good airflow already.

The deal is with these is they have an exponential (geez that hurt my head) effect. The gains are more reliant on the rest of you performance setup. If you have a good ram air setup you will notice a big difference. If you have a turbo you will also, it is suggested that you put one before and after the turbine. It is also suggested that you put two in on NA setups aswell to keep the aiflow spiraling throughout the full distance of you intake, so one close to you filter and the other near the throttle opening. If you aint getting any air in to start with they won;t do jack but if you are, bingo...

We have a version of these in Oz and they are called Hiclone, goto www.hiclone.com.au this site gives a good explanation of how it works...

did you guys go to the spiral illusion thingy on that website. Its towards the bottom. You have to click on a link. Look at it really close for like 1 minute then move back to a normal distance from your computer and it will look like your computer is moving

One suggestion..look into something besides a dynomax exhaust...mine has a horrible rattle sound from it...everything is tight and all...but it's like resonance or something. Sounds horrible when you first start it up...when it gets warm its ok though...I'm probably gonna change exhausts soon
