turbo rebuld

[T5frankie]

i can get a kkk24 for £100 but it need a rebuild is this economically viable and with this turbo do i need a straight or angled 3" downpipe?

[Santa]

Think its about £350 for a rebuild but be ware that the housing may have hairline cracks in it...then its a write-off. (This happened to mine when I sent it away for refurb, ended up buying a new turbo).

how much for a new one?

[Santa]

how much for a new one?

Cant remember (I try not to...it keeps me sane). £700 ish rings a bell

[Wobbly Dave]

for that price you'd better of with the 19.

[T5frankie]

yeah i wanna bit more power than what a 19t will give me there aint alot of difference to that and what i have now

[Wobbly Dave]

what are you aiming for??

[smithy]

the kkk24 is well known for cracking mate so i say no no .if i was you 19t or your 18t modded or a garrett like mine then 26 psi all day long

[Wobbly Dave]

but you need to forge the bottom end to do that right?

[t5 pete]

but you need to forge the bottom end to do that right?

I certainly wouldnt like to risk it with out aspically when the boost comes in

[smithy]

but you need to forge the bottom end to do that right?

you could run a 2 stage boost say 1.2 at 3k then 1.6 at 4k that should help the rods a tad but i though he was going to forge his spare engine though

[claymore]

so 26psi would be to much for a standard engine? Mine will be boosting 6psi from tick over...:(
what would be a safe boost level on standard internals?

[Wobbly Dave]

depends on how soon you bring it in. 1.3 is about the limit I believe.

[claymore]

depends on how soon you bring it in. 1.3 is about the limit I believe.
I'm running more than that now.

[smithy]

1.4 is about max on a small turbo but the bigger turbo come in lata so might be able to run more

[claymore]

Mine will have an SC as well

[Santa]

Bigger turbo air temperature will be lower as well so you get denser (is that a word?) air at similar pressure but may be able to push it slightly higher as well

[T5frankie]

what are you aiming for??

i want 380-400bhp mate

[claymore]

I intend to run the turbo atabout 14psi and make up the rest of the boost with the Supercharger, with 2 intercoolers.

[T5frankie]

you could run a 2 stage boost say 1.2 at 3k then 1.6 at 4k that should help the rods a tad but i though he was going to forge his spare engine though

it was at 1.5 at the rolling road day lol turned down to 1.1 bar now (16psi)

[T5frankie]

i still need to know what downpipe to buy

[p fandango]

denser (is that a word?)
yep, correct spelling as well

[smithy]

i want 380-400bhp mate

not with a 19t you wont but as i said before 350 bhp tuned properly will be a fast car and i know that james car will be fast with the turbo off my car dont worry about that mate

[p fandango]

i still need to know what downpipe to buy
depends what turbo you get

[smithy]

i still need to know what downpipe to buy

also my turbo fits the standard downpipe too bonus

[T5frankie]

not with a 19t you wont but as i said before 350 bhp tuned properly will be a fast car and i know that james car will be fast with the turbo off my car dont worry about that mate

never said i wanted a 19t, is that the only turbo that i will need an angled downpipe for?

[T5frankie]

decat pipe and straight through exhaust as well

[smithy]

never said i wanted a 19t, is that the only turbo that i will need an angled downpipe for?

all the volvo later turbos need an angled down pipe mate .i ran a race cat on my v70 with a 3in system up to the turbo then it was reduced to 2 3/4 to turbo

[Wobbly Dave]

Well I have worked it out & you need to be making about 360 Ft Lbs at around the 5700 mark to make 390 bhp.

[T5frankie]

Well I have worked it out & you need to be making about 360 Ft Lbs at around the 5700 mark to make 390 bhp.

well its making 335lb ft at 4000rpm and 262bhp then goes down rather than climb hence i need a bigger turbo

[smithy]

it dont thing the power figuires work like that mate it all depends on the setup

[t5 pete]

if the power is dropping of eairly have you looked at the timing

[T5frankie]

if the power is dropping of eairly have you looked at the timing

but the car is running sweet, smooth no lumpiness etc

[T5frankie]

if anyone else has a dyno graph where did you get peak horsepower in the rev range?

[smithy]

if anyone else has a dyno graph where did you get peak horsepower in the rev range?

6k mate then hit the rev limiter

[T5frankie]

6k mate then hit the rev limiter

anybody with a t5 who was at hlm? just checked my graph it made peak bhp at 4000rpm then went flat all the way to 6000 rpm the torque peaked at 4000 at 455nm then fell to 270nm at 6000 rpm

[Wobbly Dave]

it dont thing the power figuires work like that mate it all depends on the setup
You can make it sooner in the rev range but the torque will have to be sky high.

[T5frankie]

wobbly made his peak bhp figure around 5600rpm

[Santa]

hhhmmm cant quote you Dave.

Your working assumes his Rev limit is 5700 though doesnt it?

If BHP = Torque x RPM / 5252 then

Torque = BHP x 5252 / RPM

[Wobbly Dave]

No I am not assuming any rev limit - I am just working from the most common peak power point for the turbos used in Volvo.

[Santa]

aaahh ok (not sure what that was personally).

[Martin-t5r]

Speak lee owen @ owen developments if your interested in a brand new 19t, kkk or Garrett, they are Cheaper than most places including Volvo. they will custom spec a 19t with a billet compressor wheel, they will also port the housing and all sorts of other trickery to get alot more from the turbo. Kkk are good turbos but I've found from research and mates that have had them and ran them for a long time, that they will poo the bed long before a 19t will

[Wobbly Dave]

Based on 1000 rpm steps from 2000 rpm - this is what you would have to make in NM to bring home 380bhp...

2000 rpm - 1353
3000 rpm - 902
4000 rpm - 676
5000 rpm - 541
5700 rpm - 475
6000 rpm - 451
7000 rpm - 387

all i have to say is im happy with mine and mines a garett

[Martin-t5r]

Absolutely agree, Garett is the way forward if have the money to : ) I mean personally I prefer a 19t of all the relatively oem fit turbos

[Wobbly Dave]

It is important to realise that the torque & power curves always cross at 5252 (assuming that torque is in ft lbs).

[Santa]

all i have to say is im happy with mine and mines a garett

And all I have to say is I'm on my second KKK

[Martin-t5r]

How come your on your second kkk?

[Santa]

How come your on your second kkk?

Hairline cracks in the housing

[smithy]

Hairline cracks in the housing

another advantage is the rebuild costs are cheap compared to some turbos including the gt range very expensive

[smithy]

it is proberly the best turbo or a 18t for oem specs

[Wobbly Dave]

Hairline cracks in the housing
Is that a materials problem or a design flaw?

[smithy]

Is that a materials problem or a design flaw?

when you push them too far its the heat that cracks the exhaust housing they are alright when run standard but when you push them problems start to accur

[Wobbly Dave]

so its a design limitation. Walls must be too thin for the higher pressure?

[Martin-t5r]

A friend of mines exhaust housing cracked on his kkk too, he now runs a gt3071 but advised an 18 or 19 for myself, I would love a Garett though, for me it isn't the cost of the garett itself but all the flanges, feeds, modifying ( changing plastic bearing cage for metal ones etc ) just can't justify it at the moment : (

[smithy]

i think so because theses problems are common so i think the 19t is a better option or even hlm hybrid is suposed to be good but i think the is heat soak issues with that turbo if pushed too far like any small to med turbo

my is a 1 off t35 hybrid mate made to fit 850/70 no plastic bearings just a builk of solid metal lol

[Martin-t5r]

That sounds good mate where was that supplied? I think for now I will have keep dreaming, a quaife is the next logical step for me, which should be ordering this week

turbotechnics mate i know them well now and get on well with the designer .this turbo is going on jamest5r and im having a t38 hybrid with a special inset where the inlet wheel is and its a custom build a 1 off designed for my car

[Wobbly Dave]

I know "turbo dave" was responsible for designing the HLM Hybrid & he runs the fastest street bike in Europe over the standing quarter

ive heard it is a good turbo

[Wobbly Dave]

I would have had one - had I not already got a 19T.

[smithy]

im happy with mine you know the car that giggles etc lol

[Wobbly Dave]

It was meant as a compliment. LOL.

On a separate matter - I confess I grow impatient since the rolling road day to get the rest of my ATM map. All this talk of turbos & horsepower has my brain spooling up.

i know what you mean im saving at mo for all my bits and pieces and a full respray and new rims

[Santa]

I would go as far to say the housing probably has imperfections from the factory and hairline cracks can therefore happen at stock power.

On another tangent.....Viva Performance do a KKK hybrid.....ok it costs quite a bit but they do a $1000 rebate once they receive the old KKK. (Check their terms and conditions though).

i will still keep with the garrett though

Oh yeah if anyone is prepared to go down the Garrett route then do it if you want a reliable turbo that can shift lots of air.

i totally agree mine does that nicely thats why im going bigger for even more air lol

yes mate but i still had a t35 in there on my v70

easy when you know how and have the space and tools etc etc

it was built to fit mate by turbotechnics as a 1 off design because the t28 didnot work on my car so they built a turbo that would work

[T5frankie]

hmm turbo technics they are based about 3 miles from my house lol

Soon to be on a 850, will take a photo for you Frank:hidesbehi

yes we will take photos of the 18t with the t35 hybrid next to it and the t38 hybrid next to that now just got to ern some dosh now
