As titled would like some advice. Ive had this problem for a while now, ive even changed headers, turbo and still got same issue, had this problem even on top mount with standard headers, Im on td05 16g and I dont get 1bar of boost til 4k rpm and full boost around 4-500rpm later. JGM was on the lappy doing his thing but had no luck, we checked the actuator and adjusted it but still no luck, intake pipe has a split by turbo which simon said that could be the issue but would like to know if anyone else has had this problem and shed some light on what it could be, there are no headers leaks or air leaks, ive even changed my turbo, don't mind chaning little things to see what the issue is before I change the turbo AGAIN any advice would be appreciated thankyou

Tried a Harvey up-pipe?

Now available from AS Performance, designed to allow spool much earlier.

With ported headers, or tubular if you are running enough bhp and have the 2.5, the Harvey up-pipe works a treat. Mine spools incredibly early, 2.5, tubular headers, Harvey up-pipe and HS TD05 20g.

I had a harveys smith uppipe on my old setup and it was still the same..

What FMIC or you still running TMIC?

Something still not adding me up,just due 16G spool nicely like on WRX or STi,in which gear you are testing the spool?

On 5speed you should be testing in 3rd gear,on 6speed in 4th you should be testing spool

I've got a similar problem. Fmic, ported an wrapped headers, AS performance trick up pipe

Reaching 1 bar around 3500rpm, full boost - 1.3 bar at just over 4k

Feels abit lazy out of bends. BUT when she does come chat

I've heard this is normal characteristics for a TD05?

TD04 for the real world win, the only other thing that gets close is a VF34 if your after more top end power, but they are like rocking horse poo these days, and the SC Billet's are too much money for my liking.

Just dont get it, its too laggy, its only a 16g, ive got fmic, gt spec headers,, I had the same problem when I was on top mount and oe headers! I get 1 bar at 3800 and full boost around 4400 , testing spool in 3rd gear 5 speed box

Would you need a remap if you fit a Harvey smith trick up pipe

alcazar

iTrader: (2)

You get it mapped for it? Ported or tubular headers?

alcazar

iTrader: (2)

Not mine, it ain't. I have one bar of boost sub 2800rpm.

alcazar

iTrader: (2)

Best to have it mapped to get the best out of it. Either fit, or have your own ported headers.

The two go together. It's all about gas-flow.

get an andy f hybrid td04 and be done with it. considering one myself for the wagon.

veerinder9

iTrader: (1)

I may try a vf turbo but just dont know which one, I want a solid 350bhp and nice spool, and yes it was mapped with trick uppipe and tubular headers.

veerinder9

iTrader: (1)

But my question is would a split intake cause lag? Bearing in mind im running new alcatek mafless

alcazar

iTrader: (2)

I would say so. Anything that slows the gases down is going to cause lag, isn't it?

veerinder9

iTrader: (1)

Its intake pipe? Its just atmosphere air?

yabbadoo4

iTrader: (8)

a 34 or a 35 is what you,ll want then. when my wagon was mapped by andy f there was a guy from sidc with a gb270 (i think) he got 360 bhp on his car with a vf35

jura11

iTrader: (7)

If split intake can cause lag,not sure,but usually can cause some other bits such as can run lean and you will be down on the power

Do you have in your area any RR,if yes I would go on the Dyno run

Something is wrong. Is it a genuine td05. I run one although an 18g version. 1 bar below 3k and 1.5 by 3200rpm.

alcazar

iTrader: (2)

It does sound as if it's either not been mapped properly, or it's not a genuine TD05.

veerinder9

iTrader: (1)

Its been mapped by JGM on alcatek, and yes its a genuine td05 90 degree turbo converted to a front entry

Hang on...just reading back...tubular headers????

the late, great Harvey Smith told me NOT to go tubular until around 400bhp and with a BIG turbo.

Maybe that's your problem? Who advised tubular headers, and which ones do you have?
harvey told me ported Scoob headers up to 400. Around 400 there is a choice, over 400, tubular. And he did mention spool.

veerinder9

iTrader: (1)

If you read back I had the same prob on normal headers, also JGM said that he would go for tubulars as u get more midrange torque and they are gt spec headers

alcazar

iTrader: (2)

Opposite advice to Harvey........and mine runs great with VERY low down spool.

Your car, your choice.

veerinder9

iTrader: (1)

But I had the same problem on normal headers! Still boosting the same

alcazar

iTrader: (2)

So get the split repaired etc and go from there.

There HAS to be a reason why yours won't spool and mine does.

veerinder9

Thats the plan on tuesday, will see what happens but I think there may be something else, also since ive had it mapped and boost put up to 1.5 bar its leaking oil, haf a lil bit of oil in intercooler pipe, its pushing oil through cam seals could this be anothet reason why its coming in late? Do I need a catch can?

alcazar

iTrader: (2)

You done the crankcase breather mod?

veerinder9

iTrader: (1)

Nope I havnt

Worth doing imho.
