1.8T 20v turbo manifold test: 1.25" vs 1.5" + Holset HX35 turbo test | GTS gets tuned at JVS 

Thanks Savin. Trying my best to keep it coming. 🙏🏽

💪🏽

It is going to be a very interesting race. 😬

Thanks a lot. Appreciate it. 🙌

It sounds wild. My eardrums did not like it in the dyno room. Haha. Seeing the flames is cool though. Pity it's not "legal" for the street racing events at Killarney.

The life I didn't know I signed up for. But it's interesting. Always something new to learn.

Glad you enjoyed it! GTS is coming out with a vengeance soon. 💪🏽

That's good gains. 💪🏽 We weren't really looking for power gains. Just wanted to see if it would move the powerband.

For me was just to get a bettir spool and ja it did help

@@donovanoosthuizen7739 Can you remember how much extra rpm you got in spool up?

@@lowdl it spooled from 4500 now 3800 its boosts

@@lowdl and my car only revs to 7000 but i did rebuild the motor all most similer to yours and just done 350km on it so think it wil be better

That diesel ran away after they jump started it. I didn't know that blocking the intake is the key. I need to know this. Wouldn't want it happening o my daily.

@Lorenzo Lakay also use something solid that won't get sucked up

It's happening to a lot of guys. That's how it goes with RU-vid unfortunately. But glad you're back.

It's very odd. It was interesting but something isn't right. lol. It should have spooled up quicker. It's like it won't change no matter what combo we try. Twinscroll is great. Sounds like you've got a good combo. 2 bar just over 4k is epic. I think that setup only hit 1.8 bar around 6k rpm.

@@lowdl doesn't seem right at all lol , when I did my research I came up on a article of a 4g63 header size experiment and it had way better low- midrange on the smaller size runners and the benefits were minimal upsizing to 1.5" and it was making 700hp , so this was very confusing to see 🙈😂 unless the 20v just needs the flow more than we thought , also loved the cam tests you did man , great content and well put out videos thanks for posting your finds on everything you're trying

@@armandbeyers2935 I read the same article and it was very interesting. It was part of the reason I wanted to do this test. And I looked at a lot of the Badger5 graphs to see how their setups spool. I don't think my test has anything to do with the 20v flow. I think there's another issue and this just made me eager to find and fix it. There's at least 500 rpm to be gained. Glad you're enjoying the content 💪🏽

Very surprising. I've seen quite a few Holset graphs and the guys generally have good results with that turbo. More data to work with is good. Maybe there's more in it with some tweaking.

I agree with the dyno load issue. See it happen all the time with open loop boost strategy. I didn't test any of the other tested setups on the road. It wasn't exactly road friendly but I should have to see what it does on the logs.

😬

I'm not too sure, should take 2.4/5 bar fine. But won't be going above 2.0/1 bar. Glad you're enjoying the videos 💪🏽

I have thought about doing a intake but it's not cheap... for the one I want that is. There are gains to be had but it's also one of those things where if you go too big, you can lose power.

🙌🏽

This is the turbo specs: Compressor Wheel: 54*67mm Turbine Wheel: 54*49mm Fueling for these tests was E40 and yes I'm running meth injection. Fueling setup is stock Mk2 GTI high pressure pump.

@@lowdl sounds like the turbo is the 5449g model? On the holset do you have the comp and turbine specs? I am assuming T3?

@@321ror Yes that's correct. No idea on the Holset wheel specs other than it coming up a HX35. It's T3 with 0.48 hotside.

There isn't a G28 that I know of, I think you're referring to a GTX28. Those are good. Would spool nicely but they're power limited. 500hp is probably pushing the limits on them, and I'd like to get my power to around 550-600hp eventually.

I haven't emptied it since it's been rebuilt nearly 2 years ago. It's starting to smoke out the breather now but there's no vapour. We had the outlet open against the wheel well and it wasn't dirty at all. I think it's because it's venting into the intake and to the catch can.

Okay that's great bro do you have a voltage meter lol. Because im trying to find someone that can add a relay to my fans because it takes alot of voltage when it comes on it drops to 13.2 when lights is on and 13.0 when interior fan

No headwork. It's refreshed but no performance mods.

It's a G25 660.

Where is this dyno

Mr L L whats ur number

@@WalkedArnal it's in Ottery. And J2 performance.

When did you fit the G25? Pulsar I’m guessing? Very surprised, thought the G25 would’ve spooled way quicker.

Maybe the owner of the test manifold might want to sell it or he could make you a manifold for your project.

I only have a cost breakdown for the initial build. Not all the extra stuff. But here you go, hopefully it helps: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-inc13tNWzzo.html

Much appreciated 🙏

Great content 👌

@@nkatekotruth2866 Thank you very much. 💪🏽

I didn't think a small comp wheel would make that much difference. I'll eventually go 2.0 and then this turbo will be a lot better. I'm not unhappy with the way it performs, it's just not a lot of room for error with my 3rd gear shift.

Haha. It looks dramatic but it's not that crazy... yet.

@@lowdl nah my brother keep going hope you are well
