Thank you guys. Okey with this spec on what pressure i can reach arround 250 bhp? Or give me advise what parts to put to reach arround 250 bhp?
Thank you :)
Question is will the spec you got do 250bhp. Its a hard one to answer as is seems every volvo lump being built use's a different sort of cam and set up so all will vary and hard to say what one produces what power.
What fuel pump, intercooler, throttle body, exhaust, spec of T3 you using?

Re: Volvo Engine - What BHP from stock??
looks like there may be a rolling road day so id like to see what power im running would be very pleased with 180bhp. Im sure the standard injectors can fuel for more than 18psi boost tho as mine goes down as low as 10 at wot I have adjusted the maf sensor now to sort this a little but my turbo can only really produce 18psi realisticly so cant try it:sad2:

The fuel pump it will be walbro 255l/h . The intercooler i didn't choose yet it will be one of thoose
http://cgi.ebay.co.uk/FRONT-MOUNT-UN...item2c535c391d or this one
http://cgi.ebay.co.uk/NEW-MEDIUM-Int...item1c15a0dc8f
or this one
http://cgi.ebay.co.uk/NEW-SMALL-Inte...item1c16126144
The throttle body it will be from vauxhall 2.0 8v engine. The exhaust it will be 2.5 inch. The turbo it will be from ford rs turbo or from lancia dedra or other. What type of garrett t3 to look with what Trim to be?

Re: Volvo Engine - What BHP from stock??
If your after abit of power why not go for a Cosworth T3 to start with and go from there. Not too sure what the flange pattern is but sure you'll have to mod the volvo manifold to accept a T3 flange if its still 4-bolt holes.
Intercooler wise, i'd prob go for middle one or bottom one.
-
Re: Volvo Engine - What BHP from stock??
would have thought a t3 would be a bit laggy lots of people are using t28's on these engines with good results and should be more than up to the job of 250bhp. Why a vauxhall 2L TB? Have you looked at the 2L N/A volvo TB's?

Re: Volvo Engine - What BHP from stock??
My friend run his Volvo with bits he had kicking about the workshop quite a few years ago.
Standard 440 turbo block crank and pistons, Ported head, Reprofiled valves, Vauxhall cavalier trottle body, T3 turbo 48a/r exhuast housing 42 compressor housing modified for 2wd cosworth compressor wheel 360 degree thrust bearing, Dot 31 actuator, Subaru impreza fuel pump, Omex 500 engine management, Sierra cosworth yellow injectors, Frontera 2.4turbo diesel alloy intercooler, 2.5bar map sensor, Blitz E-SBC boost controller, K&N air filter, HKS iridium plugs,

I didn't look the volvo tb. One of my friends in Bulgaria is with the same engine with garrett t3 and he says that the turbo kicks from 3000 rpm. Which for me is still okey.

Re: Volvo Engine - What BHP from stock??
boost at 3k is very good going.

Re: Volvo Engine - What BHP from stock??
if it helps heres my graph
this is prety much a stock engine with a different cam and injectors. using a t28 from a 200sx.
oh an 2 of the gear box ooooops:)

piper did mine, they made it a 279, i had to also buy some shims, the whole lot was £200-300 i can not remember

Re: Volvo Engine - What BHP from stock??
Is that 30psi boost youre running dave to make the 230bhp?:scratch:
-
Re: Volvo Engine - What BHP from stock??
From what i can see on his dyno graph it makes about 20psi at 3500rpm and holds around 18psi. I think they're Great results for that boost. I thought it took about 25psi to make 230 bhp. Well done dave:agree: im guessing the Dta management helps.

what boxes were they and what ft lb did the your engine produce to break them:eek:
the reason im asking ,is that i dont want mine going the same way:cry::cry: them piccys will give me nightmares:ashamed:
-
Re: Volvo Engine - What BHP from stock??
Ah i get it now:ashamed::cartman:
would 18psi on a t28 make more power than a t2/25 at 18psi all other things being equal thats what i keep hearing but why??:scratch:
-
Re: Volvo Engine - What BHP from stock??
flows more air ,simplezz;)
or t3 even more air:D
-
Re: Volvo Engine - What BHP from stock??
still dont get it:cartman: if the smaller turbo is forcing air into the engine at 18psi then more air from the larger turbo would mean more psi of boost wouldnt it:scratch:
-
Re: Volvo Engine - What BHP from stock??
your wastegate will still regulate final boost pressure , but because your bigger turbo will generate less heat /flow bigger volume of compressed air(compressor/turbine) you should get more power, plus you wont be working that t28 quite as hard so your engine bay should stay cooler also, which will help with all that engine in the tiny 5 gtt bay:)
-
Re: Volvo Engine - What BHP from stock??
if you imagine blowing through a straw ,and then blowing through a 2"waste pipe ,the 2"waste pipe will be less restrictive.
simple terms and not exactly scientific/technical , but hope that helps
the less restrictive, the less heat is produced ,and heat robs oxygen and overall power
if i'm wrong the more worthy among us ,will take notice and reply
no piss taking comments please!!:p

Re: Volvo Engine - What BHP from stock??
makes sense. so if im running a t2/25 at 18psi boost and its rich in that case a t28 at 18psi would lean it out and make me more power?:D

yes,more air in the cylinders ,which will weaken your air to fuel ratio mix, but you would still need to get the afr's just right to achieve the best possible burn, which should give you maxium power output,but cam timing ,and inlet temps,flow will all make a difference to overall output, the world of tuning has many twists and turns ,and finding the perfect setup is an art, and comes with time and practice / experience of which i have very little:laugh::laugh:
-
Re: Volvo Engine - What BHP from stock??
its like a table fan blowing alot slower to generate air compared to a hairdryer whizzing its nuts of to generate the same volume, sorry if thats a bad example to :)
-
Re: Volvo Engine - What BHP from stock??
the bigger the turbo the more lag you will get(longer to spool up the turbo) but will give you more power ,but its getting the balance right , for how you want the car to perform:D
-
Re: Volvo Engine - What BHP from stock??
ermm may have to get a t28 then:D dont think there too laggy on these lumps apparently.

Re: Volvo Engine - What BHP from stock??
theres a few reasons large turbos make more power.....temp has little actual effect.
the turbine is largely responsable for making more power at the same boost levels, as larger turbos usually have both a larger compressor, and a larger turbine.
the turbine "corks" the exhaust, and restricts flow, which kills power.
so a larger turbine will not "cork" it as much, and hence flow more at the same pressure (allbeit at the expense of spool time).
secondly, the larger compressor has more ability to keep the cylinders full as rpm rises, (where a smaller compressor will tail off). simply put, large compressors "carry" torque higher. and if you make more torque at higher rpm, you make more hp, since hp = toquexrevs/5252.
i.e if you make 200ft/lb at 5000revs you make 190bhp.
if you make the same 200ft/lb but at 7000revs you make 266bhp.

Re: Volvo Engine - What BHP from stock??
should go very well, with little lag ,have a look around on the forum and find out who's running the b18f and pm them, im sure they will let you know, or pm Adam L , he should be able to guide you on what size/ ar's your after:agree::cool:

larger turbo it is then:D
so is it true then that engines make the same bhp at 5252rpm? as that one really confuesd me:confused::D:wasntme:

have heard that t28's go really well on these engines but have no idea on comp sizes and a/r etc...:confused:

Gary, just buy a 200 sx T28 or pulsar T28 matey and slap it on stop fannying about with the pidly little turbo you have on there at the mo. Get some real power out of the engine you have

well for starters speak to rob who posted above , he is running the same engine as you and is well into the heavy development side of it , will know the engine better than most:D

stands to reason it wont go aswell as a larger turbined/comp unit would....
depends what you want from the car, peak hp, or drivability

James as your vnt's doing nothing atm fancy slapping it my car and see what it can do:D
Which one is the better of the two turbos? I know either the 200sx is the upgrade for the pulsar or the other way around i forget:(
-
Re: Volvo Engine - What BHP from stock??
decide what YOU want from the car, fast resonse or big power , and go from there , i would suggest a new turbo with 360 bearings /well balanced, and stay away from secondhand/unknown units ,cheap is not always best and ,can destroy all the hardwork of fitting your engine:)
-
Re: Volvo Engine - What BHP from stock??
im using the car as a road car and im not really going to be trying to break any 1/4mile times but would like some decent power. Over 200bhp would be great but i like my boost early and wouldnt really like to substitute driveability for power need the power there when i want it tho. Not asking for much:wasntme:

Re: Volvo Engine - What BHP from stock??
I have a t2/25 from turbo technics has a 360 degree thrust bearing and is nearer a full t25 than a t2. Its doing the job well at the moment but would like more power but i like the fact that i get full boost before 3000rpm

like i said , pm a few members with the b18f and see what they say and go from there , but a cheap unit from china etc is not going to last very long, and can destroy engines fairly quick if they let go:laugh:

what about a rollerbearing t28 that would spool up quicker than a normal t28 wouldnt it?

Yeah i think this was the direction Haz was going before he sold up. Just get a £150 t28 on gary before you start spending big bucks. If you dont like it sell it on, you wont loose any money.
