My fear also is having it start spooling way to late, I've gotten the RHF4 to start at around 1700RPM. At around what RPM do you think the TD04 will start? <br /><br />The problem I'm having with the Garrett vs the MHI is the cost factor, locally anything with the Garrett badge is about 4x more expensive than anything ells.<br /><br />Thanks<br />ChrisChrishttps://www.blogger.com/profile/06934973467803685213noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-53088695160275075512022-05-18T23:33:16.106+03:002022-05-18T23:33:16.106+03:00Hello Chris, the RHF4 turbo is already a very good...Hello Chris, the RHF4 turbo is already a very good match for the YD25 engine, however it can't give you much more power. The TD04HL-15T should give you around 140kw / 200hp however without the variable vane turbine housing you would sacrifice some spool. The GT1749V does have variable vanes however it's comparable to the RHF4 turbo. If you want some more power and still have the help of variable vanes for spool you might want to look at the GT2052v VNT turbo.JDhttps://www.blogger.com/profile/17735949883966509795noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-25371042806444543002022-05-18T08:12:32.098+03:002022-05-18T08:12:32.098+03:00Hi, I hope you can help.

And if that's the case you won't be able to only upgrade the turbo to a bigger one unless you make a custom manifold or find a manifold that would work. Either way if you do get a bigger turbo fitted you would still only be able to run around 110hp / 250nm max before the clutch starts to slip. So if you want to make a bit more power than the GT1547 turbo but keep the stock clutch you should instead consider the GT1749v turbocharger.JDhttps://www.blogger.com/profile/17735949883966509795noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-65964638514484476542022-03-22T11:36:14.514+02:002022-03-22T11:36:14.514+02:00HI JD, I HAVE A POLO 1.4TDI RUNNING AT 1.1BAR BOOS...HI JD, I HAVE A POLO 1.4TDI RUNNING AT 1.1BAR BOOST WITH STOCK GT1547 WASTEGATED TURBO.

The stock 3 bar map sensor would limit you to around 2 bar / 29 psi boost max. So you can't really go above 240hp unless you do a remap with another map sensor. However if you want to stay with a more moderate tune 200hp should not be any problems with a good tune and around 1.6 bar / 23 psi boost.JDhttps://www.blogger.com/profile/17735949883966509795noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-7994368619786552432022-02-13T00:54:46.473+02:002022-02-13T00:54:46.473+02:00Hi JD

I can't find what the max pressure the ecu or map sensor is able to read in stock form. But because it is already shown by others that stock peak is around 20 psi it could mean it's a 2 or 2.5 bar map sensor or simply that is where the map ends and the stock ecu will start to reduce power.JDhttps://www.blogger.com/profile/17735949883966509795noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-79960273815141328512021-11-05T01:32:36.349+02:002021-11-05T01:32:36.349+02:00Will the map read the boost in order to deliver th...Will the map read the boost in order to deliver the right fuel?Navara d40https://www.blogger.com/profile/05559911599159236142noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-46472283574490374582021-10-18T23:40:49.322+03:002021-10-18T23:40:49.322+03:00Hello Navara d40, you can push the boost pressure ...Hello Navara d40, you can push the boost pressure up to around 2 bar / 29 psi boost and get around 200hp.

Chances are you would still have the same airflow at higher boost pressures. But if we assume you are in a good efficient place in the compressor map right now, you could probably add 10% to the airflow with higher boost. However without knowing how the compressor map looks it's really hard to calculate.JDhttps://www.blogger.com/profile/17735949883966509795noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-62706917101485436482021-10-01T14:33:51.554+03:002021-10-01T14:33:51.554+03:00HI.

And with 960kg/h you should still be able to make around 350hp.

I'm not an expert on all of this stuff, but I'm wondering if it's problem with my hybrid turbo or there is other factor which blocks HP potential. I can see airflow on 4th gear 1040-1060kg/h , but for 5th gear there is still boost at 1.75 1.78 but airflow drops to max 960kg/h and that's why it is not producing more power.its not holding high airflow rate and on 5,6 gears I'm starting to see a lot of timing advance reductions -3° on three cylinders. I'm using higher octane petrol (ron=99). Ah one note...I asked hybrid shop to make a clipping on turbine blades. Is that something which could have some impact as well on overall performance?<br />Wilqhttps://www.blogger.com/profile/13814902300026949711noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-3212607889130702552021-09-27T02:25:05.444+03:002021-09-27T02:25:05.444+03:00Hello Wilq, looking into it more you could get aro...Hello Wilq, looking into it more you could get around 360-370hp from the updated turbo. However I think because the stock Giulia cylinder head might have rather poor airflow, and also a high 10.0 compression ratio means you are not seeing the power increase. It might be the ECU is already detecting some detonation and reducing power, or there is a set boost limit around 1.8bar.<br /><br />Because you are seeing more than 1.5bar boost I'm guessing the MAP sensor installed needs to be a 3bar Map Sensor and not the smaller 2.5bar (1.5 bar max boost) that is also found in some models. <br /><br />So that would mean max boost is going to be limited to around 2.0 bar. But you should see around 330hp with 2bar / 29 psi boost. And to get to around 350hp you would need around 2.2 bar / 32 psi boost pressure.<br /><br />Either way you won't really be able to run that high boost without running into the risk of detonation on regular fuel, and the ECU will probably limit boost/power well below that to save the engine. You can switch over and tune the car to run E85 fuel. Or one alternative is you could get a water methanol injection kit installed and see if that helps.<br /><br />But that will only work if the ECU does not have a boost limit set and you make sure you really have a 3 Bar Map Sensor. Best would be to get new pistons and drop the compression ratio to around 8.0:1. That way you could run higher boost without risk of damage.<br /><br />JDhttps://www.blogger.com/profile/17735949883966509795noreply@blogger.comtag:blogger.com,1999:blog-6670820875534775743.post-72726489182843436232021-09-27T01:24:57.043+03:002021-09-27T01:24:57.043+03:00Hi.
