I am currently in the process of building a A6 block for turbo. My goal is minimal boost daily but up to 20-25 psi when racing. A friend of mine (who I might add hates hondas, he's a mazda lover) says there is no point in running 20 psi on a FWD car. He says I will never get traction and will cause me to be slower. He said the most I could run is 8. Why is this? Wouldn't a front wheel drive car tech be better than rear wheel drive due to the engine weight giving it better traction? Plus if I go with a turbo setup the doesn't build boost till 3-4k I will already be rolling so traction shouldn't be to bad of a problem right?

You need to tell you Mazda lover to STFU.....jk....

There are plety of people running 20+ lbs of boost.....it all depends on how good of a driver you are. also riding around on slicks might help you out. And RWD cars are better for traction because there is less weight in the back.

if you're running 20psi you will be using a good stand alone.
Just tell it to lay off the boost in first and second gears at low rpm and kick it up to max later.
you don't have to be pushing 20psi in first gear.
But when you get to fourth or fifth gear

traction at 20psi is definately an issue but with practice it can be handled no problem

They also sell a lot of electronic controller like the apex'i avcr that has gear dependent boost so you could moderate the boost on 1,2nd gear and go ***** out in third.

Slicks help too.

I probably wouldn't run everyday at 20psi just at the track, or when your losing!!

Tell your mazda friend to go race Lisa Kubo. Then after he loses tell him to ask her if 8psi is too much.

yea tell him to shove his wankle up his ***

Also check out AEM's website.. Stephan runs alot more than 8 psi and hes the fastest FWD car in the world..

Well another question I have is reliablity. How long can I expect a turbo charged engine to last? Not going to run 20 psi daily. Min boost daily just 20 every now and then.

Probably a while.. Usally when you get up that high its meant for a track car only.. But I have seen cars running a good amount of boost everyday and never had a problem.. The Subaru wrx runs like 12 or 14 psi stock, cant remember which but they are a reliable car.. If you build the motor for it, it will last..

RWD is better in that, when accelerating weight transfers to the rear. Ever notice while someone is accelerating, the front lifts up while the rear squats.

Btw, you're friend is incorrect. Get a very good suspension, tires, and radius rods, you'll be fine, but you'll still spin of course.

LSD too, w/o LSD you can forget it, but alot of it has to do with driver skill. you think F-1 cars dont experience traction problems? you just dont notice cause the drivers are so damn good

BTW, i thought the WRX was only 10 -11 lbs? could be wrong though.

EDIT: are we talking a drag car, or a track car?

what?


Back on topic stop thinking in terms of "how much boost" Think about horsepower/torque instead. Depending on what setup you choose you could be making 400 whp under 12 lbs of boost. So is it just a fascination to say you run 20lbs.????

This is correct.. Your setup should dictate how much boost you should run for power.. Usally people say 7 pounds on the street and 10 at the track but this is for a stock motor.. When you build your motor for power that will change.. Alot of factors change what boost level you run.. If you are making 400hp with 12psi and are hardly getting traction, then why would you jump up to 15 psi.. set your boost for the motor your building, not building the motor for a certant boost.. If that makes sense..

And I heard from a salesman that the boost on a wrx was either 12 or 14 so that probably is wrong.. It was a salesman that told me that and he was a dumbass.. I started naming stuff under the hood and he was like "What was that thing called again"..

14 psi on the wrx!
