Another hybrid conversion thread....

Welly said:
As I have already said dude, the inside of the adapter tapers down to 51mm. Meaning that a K04, with this 3" adapter fitted, looks very much like this:

It has a smooth taper from 76mm to 51mm. The pipe fits around the outside.

Ahh cool, hope it works
 
Thanks for that mark, I read it wrong, sorry dude.

I actually was trying to do the exact same thing few months back with my local exhaust fabricator but when I thought about it how I have explained above I didnt take it any further. Im looking forward to the results you get an if they are good could be a future mod.

When i first read you was having boost creep, the first thing that came to my head was the actuator was getting weak as you can get boost creep from weak actuators running internal wastegates but BIll sorted that out. I see what your saying though you could get more power from lower boost with more timing.

Thats cool dude, no problemo.

I agree, results will be very interesting indeed.

Yeah, I'm just not really convinced that the smaller diameter intake on the turbo wont act as a sort of bottle neck.

I'm just about to fit a Garrett turbo with 2 1/2" intake and 3" MAF. I have loads of smaller diameter silicone and aluminium but nothing 3".

I'll be very interested to see the figures with your 3" TIP fitted.
Click to expand...

look at your TIPs
Look at the bend before the turbo
Look at its diameter

losse's are incurred
Those who have made their own 3" TIP's have gained everywhere. This is the hope from the one I am making. We will see. Pretty confident it will yield gains.
losses on intake are multiplied by the compressors pressure ratio... turbos blow well, they dont suck so well.

How is the Adapter clamping onto the Turbo inlet?? Is that a small Grub screw I can see in the photo??
Click to expand...

yes. grub screw which locates in the k04's inlet groove.
add some gasket sealer to the ID to make the airtight seal for good measure, and the grub screws will secure it mechanically
 
Hmmmmm I wasn't expecting such a heated response. You 8L lot are an aggressive bunch!! PMSL

Look forward to seeing the results.

I know what he is doing, just cant understand the point....

I think Wellys car would beneifit from a uprated actuator as well as a TIP. Be able to run bit more torque and sustain boost a bit better ini.

Nathan

you are'nt getting it nattie

uprated actuator??? what do you think its doing?

sustaining boost in this application has nothing to do with actuator pressure and everything to do with compressor capacity
aka its run out of puff up top so cannot sustain and more.

Im not saying it an issue just can get my head around it. I was just looking for a explaination which I can understand the point to what wellys trying to do.

Its ME who is doing this, and Wellys is the willing victim for testing. I wanted to try this as I have dyno'd an LCR on hybrid which had a diy 3" TIP and it worked and it flowed very well. the cavitation all too common on 210/225 engines once mapped can be eliminated from this larger intake I believe..

3" TIP sound info all good too me, proper DIY modding / experimenting look forward to seeing the results. Makes for excellent reading

I am experiencing cavitation on my Hybrid, its ****** annoying and Bill if your TIP solves this i think it will a worthwhile exercise in itself.
 
The 3" adaptor I have had made

Did'nt get much done on it last night..
need to get some pipe fittings to weld onto it.. off to forge later to go shopping
:)

you still dont understand what creep is Nathan
you studying this at uni currently? your a student yea?

*maybe* more book time and less pub time perhaps..

creep is'nt weak actuator, moreover inadequate wastegate size to flow/bypass the flow

I dont got to pubs Bill. We havent actually studied this stuff. I have just gone by experience me and my mate had with boost creep. He was having boost creep and we changed to a stiffer actuator and it cured it.

I have actually just looked it up in a book I have and boost creep is when the size of the wastegate is not big enough to allow the exhaust gases past through it. So when the wastegate is fully open it cannot allow enough exhaust flow to past through it so you get boost creep, in a general summary.

If that not the right explaination for boost creep correct it please.

Nathan
 
Bill that adapter is awesome mate, I NEED one of those.

tho i would leave my headlight out so everyone can see it.LOL
 
Lol I rarely drink, only on occasions really. Only time you will find me in a pub is to kick *** on the pool table lol.
Its funny though because the people who tend to have a hundred of stories to tell about 'what happened last night' tend to always have rubbish grades lol. Im not a boring one though who loves to stay in and study lol.

What you studying Mark

do you not actually read whats typed???? *** man you are more than frustrating! Its pointless trying to respoind to you when you just dont read whats typed..

from the post you replied to:

Click to expand...

What are you actually studying which requires you to want a compressor map off me, but not know what boost creep is because you have'nt studied it yet? I am intrigued.

Student = Pubs = Synonymous I thought

my bad if not the case ;)

:p

Wow you can be a right assy cant you. I did read what you said but thought I would put it in my own words of what i understand boost creep to be, is that ok with you Bill......

Dude I have literally just started studying turbos in detail as im doing my final year project on the new F1 turbo engines being designed. I was asking for compressor maps as i was going to do an engine simulation on a S3 but havent got a head to get accurate measurements. I am studying, meaning learning ........

No need for assy coments. If im that frustrating dont reply to my comments.

Now there's an offer I cant refuse..

I have not got time to waste on you, that much I know, and when you ask questions on whats already been answered it annoys me, as I am simply wasting my time I have precious little of.

I do not have inclination or time to waste debating with you when you just do not appear to listen or understand.

I might seem arsey to you, but if you were having your time wasted by someone, I am sure you would be even less tolerant or obliging with information.

Good luck with your studying. Hope it all works out for you.
 
Dude how am I wasting your time, you dont have to reply back if you havent got time. If I dont understand something or say something which is not correct I expect someone (usually you) to correct it, which you did.

However I when and looked it up myself and to get a more technical idea and posted back my understand of something which I didnt understand very well, which was what you said basically but wanted to know a bit more so when and looked it up, what is wrong with that. All you have to say is ye thats correct now or you still dont get it, or not even reply back if its wasting your time that much.

At the end of the day your one of the more knowlegable people when it comes to technical stuff which is what im after so if I say something which is wrong or dont make sense and you correct it im happy but theres no need to get funny if I dont understand something which I want to know about.

your very frustrating Nattie.. to not just me.. Please realise this.

anyhows...
picked up some bits of forge and will continue the pipe malarkie tonight all being well.
watch this space folks.. we're getting closer
ta!

****** hell, from suggesting an opinion too im frustrating to you and other (care to say who else im frustrating too) WTF.

Wont bothering reply to this thread anymore if thats the case. Sorry Welly to the way your thread has gone dude.

Nathan
 
Bill, stunning work on the adaptor!!!

Nathan, I actually quite glad you've asked all these questions, as I have no idea on these things, so this thread has really been a learning curve for me :) Thanks for the answers Bill/Paul/The Wellingsesess

Sorry but i disagree, forums area place to educate and help people, with like minded people.
I have learnt alot on here, and have helped many too...
Nathan is learning as we all are and nobody knows everything...
It gets very snobby/clicky on here sometimes....
just my 2 pence worth....:yes:

Shall we leave this behind now? The last page was entirely bitching about this and that (largely from me I grant you), and we're sort of losing the point of the thread...

The TIP is being made. It will be fitted. It will be tested. The results will speak for themselves.

Everyone cool with this?
