Ive finally got round to fitting my MBC and boost gauge today, havnt been out to adjust it and set it yet, but i will soon.

Quick question, for my boost gauge i just tapped into the vac line under the steering column (for standard gauge), will this affect the reading or is that fine?

Thats the only issue i can really think off, i'll be back in a bit to let you all know how it goes :)

The correct mathematical formula is MBC + T5frankie = wrecked T5 engine

Don't worry, I shan't be venturing over 10psi

to answer the original question, yes that will be fine :)

ok, so theres a problem. of course there is, there always f###### is! lol

No matter how i adjust the boost controller the boost flies straight past 10psi and beyond! Ive screwed it almost all the way out and back in over half way and no difference. My MBC is the screw with lock nut and spring inside it type jobby. It does have a small hole in the top, should it?

Wind it in mate, not out. Winding it out will give you more boost.
Strat from all the way in and adjust it out from there.

The instructions for it say to wind it anti-clockwise (out) and start from there, i assumed winding it in makes the cylinder smaller thus increasing the pressure. Correct me if im wrong, i've never had experience with MBC's before.

Ive run an unos mbc for over 3yrs with no problems, with an un forged engine and 18t 20 psi was fine as long as you dont batter it till after 3.5k, with a forged block im hitting 26psi and can floor it anytime but it's made me a slower driver lol

if all you're gonna run is 15psi which is the same as what a map runs, whats the point?

i suppose with my modded 19t its pushing alot more air than a standard turbo

an MBC goes alot more of an aggressive boost than any mapped T-5 i've driven & used one for many years with no issues, only reason i ditched it because of going for the Apexi boost controller

my cheapo mbc is in the bin and the car is so much faster on the standard bcs, should have bought a couple of packets of fags, least I would have enjoyed wasting £15 and I gave up smoking 16 years ago....lol

I've just got a bleed valve, which is universally said to be crap, and have the second fastest C70 on the forum, so either the bleed valve works better than people say, or I'm an amazing driver, I'll let you all decide. :D

Don't need to worry about bending rods in that engine .are you hitting boost cut or is it chipped .and what turbo are you using .also the has been a few pics of mine posted under car chat thread

No I got banned after one of the mods started spouting tripe about how to drive on a track, even though he'd never done it himself, and I told him he was talking utter bollix.;)

I've always used a bleed valve and use one now to control boost, I find it much less prone to boost spike.

Is this the type of motor?......this was mine about 10yrs ago had a new engine fitted at Volvo. Red block single OHC 1998cc the piston skirts are short on this engine and it had piston slap even when hot like ££££££y hence the new engine which was £1500 + £500 fitting and bits and pieces, done at Taunton Volvo.

I used a Bleed Valve opened 1 1/4 turns and it went like a rocket, they are 160bhp as standard

You will have a cut out at 14psi. standard i ran 13psi

I've read that the boost you can safely run depends on different things like the rods and ecu type. I'm not sure on either in my car so I'm going to set it at 10psi to be safe, but from what ive heard It seems the red block is a pretty strong engine

I have run it at 17 and 19 psi but am happy with 15 psi I have more if I need it

Your car has 13 mm rods so no need to worry but you will hit boost cut at around 14 psi so I would run your car at 13 psi and enjoy .

I ran it at 10psi an gave it the beans on a test drive, all was well until one of coolant hoses popped. The hose that goes from the back passenger side of the cylinder head round the back of the engine and through the firewall (presumably for the heater). It's seemed odd for the increased boost pressure to make a coolant hose pop, could it just be because it was old?

More pressure always finds a weak spot mate .but I think the 2litre runs 10 psi standard or might be wrong .i know the hpt 2.3 runs 6.5 psi at 165 bhp and the lpt I have runs 4 psi at 135 bhp but I have a couple of mods so I'm at 140 bhp .

Sunday 28th July 2013, 21:07
Well it's running 10-11psi now and it's definitely more than it was running before, quite wary of it now though with my quick fix coolant hose (slid some copper pipe to the hole and clamped it)

The car seems to be running fine, no smoke or anything. Its just that it could be an explanation for a popped water hose. I might be worrying over nothing though

If I remember correctly that hose at the back of the engine is shortish and if old with the xtra torque you now have and booting it the engine will rock more so the hose came off
Rock the engine by hand to see if the engines mounts are ok or not

The standard boost is 8.7psi for the B200FT or ET giving 155/160bhp
