V70 2.5T S1 owners

**sebasteeno** · Sunday 20th September 2009, 21:05

Just wondered if there was many on here?

**Dangerous Dave** · Sunday 20th September 2009, 21:27

I have a 2.5 T in my 850 AWD if that helps?

**Marvin** · Sunday 20th September 2009, 22:12

Yep I am another 2.5T owner, only had it 6 months so much wasted time.

Is it the same 193bhp engine?

**Dangerous Dave** · Monday 21st September 2009, 13:37

Yep, 193bhp, but could be more as I've got an mbc fitted.

Whats your feedback on the MBC as its on the to do list along with about a thousand other things?

**Dangerous Dave** · Monday 21st September 2009, 21:33

Its Excellent! I got me a set up 850 clocks with the boost gauge in, and plumbed in my mbc, strated running 12psi fine, but then I refurbed my turbo, and had to re-use an old part, so its not running right at the mo.

The kick you get when it spools up is fantastic, but its best not to get pedal happy until 3,000rpm as our little turbos do spool up quicker (even though the difference is compressor wheel size compared to a 15G one is 3 or 4mm smaller!)

I've always found info on the 2.5T very hard to find as evryones obsessed with the T5 and 'R'. If youve got any info on it you could post it would be greatly appreciated.

BTW im sure ive read that you go to 15 or 18psi on these or am i talking bo lax?

Is that the 193 to 238bhp remap or something else?

i have built 1 to potential of 400 bhp so i know a little bit about them

**V70Stu** · Tuesday 22nd September 2009, 00:09

I have one too!

**Dangerous Dave** · Tuesday 22nd September 2009, 08:08

I tried to find out if I could get the remap done at HLM for the £150 offer, but Hamish never got back to me (said he'd never heard of my ecu number and would have to look it up), and I couldn't be bothered to ask again.

I think the boost cut on the standard ecu is at 14.7psi, and I've hit it a couple of times. And I read smoewhere that the max pressure our turbos produce is 18psi. The only problem is that the wastegate actuator spring on these turbos is set weaker than the HP turbos, and the wastegate aperture is larger, but I'm not sure what pressureit will hold to.

yes the rica 1 from hlm dam good they might still have it on file. the map nocked a good 1 sec off my quater mile to 15.1 at avon .allso the 16t turbo is a direct fit and can be mapped to run on these engines no probs .the 13t is too small for running at high boost just heats up not good for power .

Not familiar with the turbo situation so am i right in saying the 2.5T has the 13t but you can upgrade to the 16t?

**Dangerous Dave** · Wednesday 23rd September 2009, 20:13

Our LPTs have the 13G, which has the straight connection to the downpipe. The 16T also has a straight flange. Although you could just swap the CHRA's over by undoing the centre clamp, that would save the hassle of removing the whole turbo.

I'm currently working on tuning my own ecu, but have a long way to go.
