Buy the book "Turbochargers" by Hugh Macinnes and open your eyes.

I did and still do not know it all.

I've never seen or heard of a turbo setup that did not have a wastegate. It's a crucial element to a turbocharged system to keep the engine from grenading due to overboost.

I have turbo knowledge and I still don't understand your meaning. There's really no "meaning" to be gleaned from a claim that factory boost systems are "5 pounds max." That's pretty unambiguous, and also quite false.

I agree !!

I agree too! I would love to get one myself at some point if I thought I could afford it. The newer TDI (turbo direct injection, I believe) engines are just in a whole different league than those weak, smelly diesels VW built back in the '70s and '80s for their Rabbits and Dashers.

With your mountain driving, I think a VW TDI and a 5-speed stick would be a match made in heaven. Probably drop it down in 4th gear and you could climb an 8 or 9 percent grade easily.

I refuse to help this OP...


Doesn't answer any of the questions asked... simply throwing up a question and checking in every once and a while to see if there is answer to their liking. Sorry OP, NO input.... NO help.

Ill make sure to point and laugh at every car I see struggling up Colorado terrain... hehehe


Mods: Can we get this sucker closed already?

Ditch the four banger and get a V6.

Dear topic starter,

Downshift going up the hill. Chances are, if you have an automatic, it's in the highest gear/overdrive right until you reach the grade that's giving you the problem. Most automatics do this, and by the time it downshifts for you, you're way out of the sweet spot where your car makes the most power/torque/go-stuff.

Many of the newer small cars (for example our 08 Yaris hatchback) have improved automatics that will downshift in a heartbeat going up or even down hills.

If it is a manual and you're having problems, the answer is the same, downshift.

Even RDX that you mentioned as having 14 psi, runs that boost only upto 4500 rpm, and then it is dropped to about 8 psi by the time it gets to 6500 rpm.
Well yeah, I have a very good understanding as to why they run low boost. That statement was just used to push my point that most factory turbo setups run quite a bit more than 5lbs of boost.

True. But that is also done with the point of maximizing output from a small displacement, anything otherwise would defeat the purpose. I was wondering about factory boost levels for various variants of VW 1.8T from about a decade ago.

I believe the older 1.8T's were still running around 9lbs (8.8 if you want to get specific).

There were several variants of it, the base version being low pressure 1.8T (about 7 psi) and going up from there in various applications.
