MBC install?????

15 posts in this topic

hey guys . i have a 2000 s40. wanted to put an MBC in to get a couple more lbs of boost. 

what boost can i run on a stock tune and injector setup safely?

what hoses off the turbo control valve do i bypass. anyone done this before?

what brand of controller do you guys like?

thanks in advance!!!

You shuld not use MBC on a S40 .. you will break the eninge in a short while. better to just get a chip tune :) saber and more hp increse!

I ran a mbc on my 2000 s40 and ran fine for 15k miles until the car caught on fire and got totaled. You do run the risk of bending your rods though. I ran 10psi made a huge difference with the exhaust upgrade.

I'd concur.  I went through a motor as well, probably most likely due to running the car at 17psi...  Eventually the turbo gave out causing the car to go through a quart of oil a week, and a spark plug every 2 days on one of the cylinders until the day I brought it into the shop with probably less than 50 miles of life left on it, it was spewing oil both through the intercooler pathways AND through the turbo dripping out of the tail pipe.  Basically a bad piston ring ultimately.  All this AFTER having had the PCV system replaced and before that having had a head gasket replacement due to a upper radiator hose that failed and snapped in half while doing about 3500 RPM near WOT going up a hill on the freeway.  After the work on both of those, it was brought to my attention about the lower compression in one of the cylinders (#3 in my case) and that even after the head gasket replacement, it was still lower than the others.  $5k and one month of down time with the car and problem was solved with a "new" low mileage motor which pulled almost as heard completely stock as my 17psi old motor did.  All I did was run an MBC and bypass the TCV...  I wouldn't recommend either.  I'd do like said above and just invest in a good reliable proven tune and goodies like exhaust and intake upgrade.  Those all will cost you less money and time than an engine replacement where you'll almost certainly like I did, for out more than the car is even worth.  Just my $0.02 and experience...

 

That all said, I used a TurboSmart Gated style MBC which I liked a lot!

upsolute does a tune where they run 12 psi but they adjust boost and fuel to compensate. the guy at upsolue said the chip tune has never caused anyone any problems. what do people normally do to boost power safely. i have an intake and a small exhaust upgrade.

have you heard of the upsolute tune. on my car they would have to solder in a new chip. i heard that can be risky? but it has shown to have good results and drivability

I've heard of a lightened fly wheel too, but have heard negative things about it also.  I can't recall what exactly though.

Upsolute is a good tune I understand, but I have heard that there are better tunes out there also and that in some cases, the Upsolute tune may be more bad than good.  Again I can't recall what exactly, but a search on here should yield that answer.

sorry not flywheel. crank pulley. i always say flywheel for some reason.

On what boards did people say it damaged their motor. I've seen you post that question everywhere.

I read flywheel as crank pulley totally knowing what you meant, lol!  I don't recall actually seeing that it damaged the motor, but could create issues with the charging system and how the alternator does what it does.  I think that's what I recall of it.  There's definitely posts places about that thought that can be searched.

The pulley isn't underdrive so it should still be good with the alternator.

The big "engine wear" is with regards to the dampener and torsion resonance causing stress on bearings usually. We're not talking balancing. In the whiteblock world there aren't a lot of posts with failures from the pulley. Older redblocks didn't even have them. There are posts from 2008 with people doing 130,000km on their UR pulleys without issues. This is definitely one of those taboo topics that you will get opinions on and I read this sort of comments. Certainly there are decent articles out there that show data points on what is reduced. There are articles that suggest because you're going through the RPM's with such variation you aren't hitting the critical frequencies for any prolonged time it's not something to worry about. I probably would not consider our cars something that are high powered and are ran in that condition for a long time. Noodle is the only other person I know who was running one in the nedcar and I don't know how many miles he has. I only have 12k miles on mine. To me this is a very inconsequential mod that has almost no gains aside from increased throttle response from a stop.

thats a good answer. i read that the lightened crank pulley does have that slight lower range torque and throttle response. especially with the auto transmissions like mine,

i also heard that on the auto transmissions that the other side of the crank has so much mass on the other side that the loss of dampening isnt really an issue at all.
