My Q4

[j1v]

wicked.

ad6. 10mm fuel lines -

What are the OEM ones?

6mm ... good for up to 400 horsepower and maybe some more. I didn't exactly need this upgrade, I just needed a fuel rail for the new intake (it's not the same as q4, neither as integrale's) and decided to go bigger just in case.

No You are just bored and didn't have nothing else to do in summer time :-)

Btw, have you got the tipo 2 alfa cam conversion degrees avaliable (change the inlet cam from 2.0 Tipo to inlet and inlet to outlet cam)

Yeah, I admit it, I was a little bored from all this lag

No, I don't ... I just put the two VIS cams, and tuned them on the dyno. They are not the best cams for turbo, but as long as I have them for free (they were in the used head I bought for this car) they are good for me

[j1v]

New cooler finally .... yes, it's a little ugly, but I hope it will be efficient

[Brul(tm)]

yes, it's a little ugly

You don't mean BIG
I am curious at the results
What about lag, do you notice the difference when driving?
The original, smal intercooler is quit fast filled whit compressed air, what about this setup?
Very intressting.

I did not drive it yet. I'm sure it will be more laggy than before. With the gt3076 it will get even more lag for sure

Hopefully the eaton (if it fits at all of course) will reduce that lag a lot ;-)

waiting for your test drive results.

ps
what's 'eaton'?

[AlfaJack]

what's 'eaton'?

An Eaton supercharger I think

[wrinx]

I guess the same...where's the jealous smiley???

Yes, I've already wrote about this on the previous page.

Eaton m62 from MB 230 Kompressor.

Lots of good work there!
A bit late now, but to reduce lag and increase power the intercooler should run the other way around:

[j1v]

btw, something I forgot to mention before.

As you can see from the dyno sheets on the previous pages, the torque split on my car is about 60%/40% front/rear, so I guess I have bought a car with replaced transmission from an 8v integrale.

What do you think about this ? Somebody with dynos of torque split of 16v grale/14 lying around to compare ?

Anyone knows good q4/16v integrale transmissions for sale ?


Thanks

Yes, that would be good, but I had a core with the other layout and it had to be used somewhere

[Stuntz]

I have complete drive not only the transmission and there are a lot of trucks whit Bulgarian plates driveing trough slovenia if you have a friend a trucker i live 6km from the main route trough the country

[Evodelta]

8v integrale F&R torque split: 56/44%
16v torque split F&R: 47/53%

To cure understeer improve your driving style and suspension!

The end tanks on your IC are very nicely formed. :-)

[arjunior45]

ok,
thanks for the 'eaton' explanation.


60/40 split was from grale rally cars {99% sure}.

[djsly]

where did you buy fuel line (10mm) and what material is it?
keep up the good work

[j1v]

a local shop. fuel/oil rubber hose

[Gery83]

Hy!
I love'd your idea, so I made it this way too.
I Like it!

Hi Gery,

welcome to the forum, it looks like you are doing some pretty interesting stuff with your Q4. Why don't you start a new thread and tell us all about it?

Steve

[j1v]

That's ok I'll not charge you for that

[Gery83]

Well, okay!
I'll do that!

[j1v]

now, let's see what do we have here

http://picasaweb.google.com/jivco.shterev/Q4StageIIIS4

Looks like a A/C compressor .... well, kind of .... and another flywheel for the other side of the engine .... well not exactly

... that's for now, the thing is in there, where it should be, I will post more interesting pics soon. Hopefully in a few weeks, I could rename this topic to "My S4" or "My QS4" or whatever ....

[AlfaJack]

Looks VERY interesting. So a 16v.SC.T

[Juan AR155Q4]

I?m really waiting to see that on the road.
Please, tons of pics.

Just don't expect to see pictures of the compressor mount, it's the ugliest thing we've ever done so far, and believe me we've done a lot of ugly things

BTW, tonight we've made the tensioner for the belt, we're progressing surprisingly quickly. These days, the one way valve should be ready, and I hope it will work.

[j1v]

One way valve prototype, version 0.01, hopefully it will work without many modifications. Just in case, because I'm an IT guy, loving to have ton of useless information, I attached it a TPS too. At least it has a spring in it and closes the door

My intentions are to use the information from the valve TPS together with the other data zeitronix logs (plenum TPS, boost, rpm) and use alarm trigger to turn on/off the compressor. Wish me luck
