Boost???

**smithson007** · Sunday 14th August 2011, 23:19

Picked up my new toy (V70R) the other night from HADI. Nice fella to deal with. Shame he's Volvo less now. LOL

Ran it about 100 miles home in really bad weather so never got chance to give it a good thrashing.
Been to york for the weekend with it and it seems to be lacking boost or just really bad turbo lag.
Its currently running a 19T and a 330 rica remap as far as i know.
It has a boost guage fitted and when accelarating it only seems to be showing around 0.5 bar but then when it gets to around 3500-4000 rpm you can feel more boost kick in but still only reaches 1.0 bar at most.
I had a S70R a few years ago that was running similar set-up and it was a complete animal.
The S70 would push you back in your seat from the word go and keep you pinned there but aint getting this from the V70 at the min.

Any suggestions as to what it could be thats holding it back so much?

Do you get bad lag from the 19t's?

Thanks very much.

Cant you give HADI a ring and see if its an issue he has had before it might be something really simple or it might just be the turbo set up but he would know.

Yes im going to give him a call tomorrow and see what he says.

Could an MBC be fitted to help?

No idea mate i dont do technical

**ROZER** · Sunday 14th August 2011, 23:55

put a code reader on it first the bcv maybe needs changing then i would clean the maf with some brake cleaner check all intercoler pipes and vac pipes make sure all pipes from and to turbo are tight with socket not screwdriver worked for me

**smithson007** · Monday 15th August 2011, 00:03

Yes ill give all those a try mate cheers. Just need to find someone that will check the codes. I refuse to pay volvo prices for doing it.

**Vikingxl** · Monday 15th August 2011, 00:11

there is a forum code reader floating about somewhere well not a forum one but one a kind member is willing to lend out

**merc85** · Monday 15th August 2011, 00:36

Mbc would help, or tighten the actuator rod, But as advised get any codes read 1st.

**mitchyboy01** · Monday 15th August 2011, 00:42

May be wrong here but wouldn't the map govern the boost so no need for MBC? Probably best to ask who you bought it from. Maybe he may have had same problem in the past??

**ROZER** · Monday 15th August 2011, 01:03

your right no need for mbc if you have rica 330 with 19t you have custom rica map you should be seeing 18 psi all day on that spec codes first if not check controls bcv. maf. map.pipework and maybe actuator rod but you need a boost gauge to set rod the correct way.but i dont think its that .

**T5frankie** · Monday 15th August 2011, 06:12

Dunno what these lot are on about but 14.5 psi sounds good for a remap mate mine only went to 12 after a map it sounds normal to me, fit an mbc and turn it up to what your happy with I advise about 18 psi though. A remap will never give you 18 psi on its own lol

yes, it improved no end once i'd fitted a 960 throttle body & enlarged RIP but was very disappointed beforehand (but had come from a 15g). 19T's can bend rods very easily & the step in boost is programmed into the map to ease the chance of bending them

**mitchyboy01** · Monday 15th August 2011, 09:52

You shouldn't need an MBC if you have a remap. Although most do for that extra bit of boost. My old car was boosting to 20psi on a 15g with a custom map, cone filter and decat exhaust. 313bhp dyno printout and Shaun 850 ran a 14.0 1/4 in it when he had it. Although I used a MBC to adjust boost and have a play with that lol

If funds allow, I would stick a MBC on it and go get a custom map to the psi you want and then you know you're car is set up for your exact spec. Also the dyno will show up any possible faults with your car, boost leaks, AFR's too rich/lean etc. It shouldn't feel sluggish with a 19t and 330 map. It should rip your arms off!!

**T5frankie** · Monday 15th August 2011, 10:47

A 330 map don't mean 330 bhp its just a mapped 19t so should should have around 290 bhp.

Yes mate, I agree. But surely if his car was anywhere near 290bhp it would still rip his arms off. There must be something wrong somewhere.

when i first had the 19t fitted the boost built up very slowly, used to give you just enough for overtaking when you first floor'd it but the boost kept rising with the revs

**T5frankie** · Monday 15th August 2011, 15:20

everything sounds fine nothing a little actuator adjustment wouldn't sort out to bring the boost in earlier

**smithson007** · Monday 15th August 2011, 17:37

Thanks for the help peeps. Theres something deffo not right with it. I was going on to stretch dual carriageway lastnight saab up my backside thought oh yes try keep up stuck my foot down very little lift, dropped it to 4th still not alot dropped to third still only doing 45 mph at most and it hardly even moved. lets just say i didnt leave the saab behind like i wanted to. LOL.
You right in what you say i was expecting it to try rip my arms off and it just aint at the min.
I ve just been out checked all hoses and everything seems tight.
Checked the actuator and there's only around 5mm of thread left showing behind the nut.
Is that normal?
What sort of money are you talking for a half decent MBC and what makes are best to go for?
Also are the Rica's just a upgraded raedy mapped ecu or are they or can they be set up to suit what your running?
Cheers.

is the actuator rod tight? or does it rattle, best off taking the turbo heat shield off (and leave it off for future work) threads are irrelevant as every car differs, as for an mbc get a forge unos, best there is mate

Yes the rod seems tight mate. Might have a little play with it later. Just dont want to break anything. Well not this soon after getting it anyways.LOL.
Might try get it on a dyno somewhere soon see what it is actually making.
