beaterX, 2.5 turns of the wga

[scheides]

Just did this on my new beaterX! 2.5 turns in on the wga and 1/3 down on the MBC yielded this:

Should have left the MBC alone I guess, peak did go down a tish, but with the mods on the car, 26psi peak is plenty for now:

Lastly, the data, for anyone that cares:

This was done on the same road, same conditions, within an hour of each other. Perfectly flat, started run in 3rd at ~2000rpm and WOT till ~7000.

The car still has the rusty exhaust and stock cat in place. I put in mlomker's used aFe drop-in the other day and decided I should try this next. Arguably worth it :)

Very nice.

I think you'd do better with an EBCS than an MBC and fiddling with the other parts, but if it's stuff that you already had lying around then it's good gains for cheap.

Nothing beats a MBC for ease of use and reliability.

Yup sticking with the mbc for now. I'll play with the ecu boost once tephra gets some of his hacks on this platform. The mbc was already on the car and the wga crank cost me 20 mins :)

I've never heard of an EBCS user having overboost issues during temperature changes...that's an MBC problem. If the ECU is great at managing that sort of thing then I don't see the point in remaining old-school.

I'm telling you now, it is an issue, I promise :) Maybe not for you, but it happens. Weather can affect MBC's as well, just not as much. A lot of guys mount their MBC's (and BCS solenoids) near their radiators to try and cut down on the variances weather can cause.

Either way, this mod isn't about MBC or BCS, its about the turbo flowing more by keeping the wastegate closed tighter; it's not holding a ton more boost anywhere, but making more power.

Have you actually tried all the different forms of boost control or just read about the online? I have. I haven't remained old school, I've gone back to old school after giving the newer/fancier/more expensive methods a chance. With my MBC mounted to the radiator fan shroud I see 1-2psi variance max due to weather changes; I saw far more than using using ECU-controlled boost. My car is also more responsive and boost hits harder/faster with a MBC. Put one on your car as a test sometime and compare the boost curve, I think you'll be quite surprised.

I look forward to doing such experimentation once the bigger mods wind down.

I'll also say that I only read the X forums and have never pretended to know shit about 8/9's. You'll be basted if you try to argue in favor of an MBC on a X forum. The X has a different ECU and I'm sure scheides will uncover a lot of interesting things as he continues exploring...

Scary, a bunch of newbs regurgitating info on the internet :) My guess is most of those guys only read something somewhere and have no actual real-world experience (must like yourself yet you still make claims regarding which is better).

With more experience you'll learn there is quite a difference between what you read online and reality.
