Hi all,

Gone in for a retune at C&V today. THe car currently has XForce with 4" dump, 5" cat into twin 2.5", Monza cooler and Siemens injectors. At the time of that tune it ran 308rwkw on 13psi trailing down to 12psi. Stock fuel pump, valve springs and turbo on a BA MkII Manual.

I have since fitted a Mal Wood Stage 3 clutch with lightened flywheel, and Rapid UBP ( Under battery pipe) and HSP (Hot Side Piping). So I am hoping it will make a little extra, also asked them to get a little more economy if possible.

Thought I would start this thread because as far as I can see, no one has results of just adding simple mods of UBP and HSP for those with a cheaper cooler setup.

Will let you know how it goes later on today.

Cya.

Good stuff dude... Be interesting to see what benefits you will see for the price of the upgrades!

Will be good info for others that dont have the cash to splash on a full kit etc so well done.

OK, just got a call from C&V.......started with 308rwkw last tune, now up to 315 rwkw with new mods in 35 degree heat.

Will post dyno graphs once I scan them tomorrow and will comment on how the car drives compared to pre UBP and HSP tune.

That's all I know for now :)

Good onya mate...I did all mine at the same time and re-tune aswell so I couldnt comment as to what gains those pipes made.. You'll notice your spool has gone up a few dB due to the metal pipes.. Sounds awsome..

So you spent $600 for tune, $295 for HSP and $140 for UBP and gained 7rwkws. How well do you think the money was spent? and can you noticed a big difference?

I suppose he did say he was looking for some economy :buttrock: interesting to see how much boost and what the AFRs look like

In response to ravenhard: Tune was $300 thanks to C&V Christmas special, pipes were $245 thanks to Rapid Group Buy and UBP was $140. UBP was done as it is a cheap mod for those with Monza coolers that many people have done. HSP was done as when I was changing the UBP I noticed a bubble in the factory rubber pipe near the entrance to the intercooler, matter of time and it would become a hole. Why replace with stock rubbish when you can spend a bit more and replace the whole lot with something decent.

I was after more economy (retune) and low down torque (larger pipes) for as little money spent as I could. What other options did I have for under $700?

I am also told by C&V the dyno room was 40 degrees or so, means I prob would have had another 8rwkw or so...... But I really don't care to be honest because the car feels better now. Economy seems better as well, about 2-3 l/100km on the trip computer.

Seat of the pants feels like there is more torque from 2000 to 3000 rpm, where I spend most of my driving. C&V put an extra 1psi of boost in as well so it is hard to guage the exact differences with just these two mods. Slight spike when hitting max boost, stock turbo probably. What I can say is, the car is far more tractable now, it does in fact grip a lot better than what it used to. How that has come about while also feeling like there is more torque down low and more top end I don't know. Maybe the dyno graphs will say something? I'm not crazy, trust me :thumbsup:

Check out the dyno graphs of old and new and tell me what you think.

The old is the 2 page PDF, the new is the jpegs. Unfortunately I never got a torque print out from the old graphs.

That boost curve just looks all wrong to me. Instead of being a linear build to mas psi, it starts off very slow then climbs very fast where it spikes and evens out.......If you look at the old graph it starts at 40kph and ends at 165kph, the new ones start at 80 and ends at 160, so I think that this dyno run was started at higher rpm in 3rd gear than say 1200rpm from the old graphs. That would explain the sudden boost increase as it was simply lag time waiting for turbo to spool from say about 2500rpm. Sounds like it makes sense.

Drove it again and it does in fact feel like it is making more torque frrom 2000 to 3000...especially from 2500 onwards.

Anyways I am happy wit hthe car and with the tune I can notice a very noticeable torque increase down low, certainly worth the money spent on a car near it's bottom end limits.

PS. THey fixed my traction control this time, used to shut down with a bit of spin, now it works quite well, a little too well in fact, won't let me spin 'em at all.
