Boost up tips wanted.

[Kingsford G]

I`m thinking of bringing a boost up still using a SBC so if I replaace turbo actuator what am I looking to buy and how much boost will b safe in a long run.The car has a Rica 310 map and boosts about 16psi a the mo.

Don't really understand your question fella? What's an SBC?

Do you have a boost guage already fitted?
You could wind the actuator rod in half a turn and see how she goes.
What's current mileage?

i think he means bcs lol, if you use a good mbc you can turn the boost up a bit, it will make the car feel alot quicker from a standstill cos the boost will come in all at once instead of progressivly with the bcs, the car will feel like an animal and will have alot more torque too, do it mate the are alot of fun just dont floor it until after 4000 rpms. you will need a boost gauge so you know when you can floor it safely and of course to set it up in the first place

....are you phase 1 or 2?

My phase 1 V70 has the HLM304 map and atm the wastegate rod has 4 turns on it which gives me reliable 18psi with NO boost creep. To put the wastegate back in the original position to get the correct amount of opening i have ordered a 18psi actuator which will put the lever back to the same position as standard but it will give 18psi.

I already have a brand new Turbo Boost Controller to protect the rods(although they are forged as standard, Vadis )

This set up will give you more punch off the line instead of risking the MBC way.

It is just a different way of doing it to get the same result but i believe it is kinder to the motor imo.

Your car doesn't have forged rods

Got the gauge fitted,mileage is 105k,BCS I ment to say sorry..Don`t really wanna use an Mbc as can`t wait till 4000rpm to floor iit lol and just wanna b on the safe side thats y I wanna do it actuator way.Might even go for an MBC probably forge as for quality.Will try actuator rod first tho.

P1 mate.How much is 18psi actuator?

[960kg]

Your car doesn't have forged rods

I only quote things i have read from Volvo sources. See attachments.

Also note max. boost figure = 24psi

This must be why tuners say this engine is good for 400bhp.

They are £45 plus shipping on ebay.

Your car has forged/uprated rods over a standard non turbo by the looks of the text. Not Forged in terms of Turbocharged engines. (B5254s NON turbo) B5234T is turbo'd

24psi is of course when the car is/was new. Not now with most over 140k

a T5 lump is a t5 lump, weather its in a R or a normal t5.

The R ones have a shiny bolts lol

??? shiny bolts ??? Mine is a lowly 850 t5s. not a R

The details are under 1997 V70 T5 B5234 T engine and it says in black and white forged.......not forged in terms of anything but forged is forged or it ain`t forged.

I have done old school tuning for over 40yrs and forged means exactly that.

Nitrided crankshaft as in the `60/`70`s Mk1 / 2 1275 Cooper S as standard is the next step down, then cast ......some other treatments may of been thrown in since but i don`t know of them.

24psi of course is not a usable boost for reliability but in the event of a blown or split Compressor / wastegate hose it shows the engine should survive the extra boost for a limited time. Nobody says it is usable boost.

Glad thats cleared that up, no point in buying some kalmar Union forged rods now. Fitting a R engine is cheaper and less time consuming

[T5frankie]

they are not forged period.... thats why we have all bent rods with much less than 24psi

Hm a bit confused.com here so if its an R model it comes forged and where does it say forged?I have to check on mine.

[merc85]

Strange considering there is only one part number for a t5 rod regardless of wether its in a R or a normal T5 lump.

Volvo part number: 9135984

Never thought they a diff tbh.

[T5frankie]

they are not forged thats how you can buy forged rods so you can run big turbos and big boost
