My Q4

[j1v]

Great work going on there. Can you tell us what are your plans for the car, are you using it on the street or just on the track. ps.. nice welding.

JimN~

I already have a track car (well not turbo and awd but fast enough, much faster than the q4 on the track I'm racing)

It is planned to be a fast street car, that I can drive at anytime of the year (especially winter time )

[j1v]

Almost done

It's quite tricky with the space this car

[markgq4]

thats looking very good J

j1v, congrats. Nice and dedicated job.
I have to admit that I'm glad I have where to learn from. What a forum, what people !
Thanks for the share.

Regards,
Chris.

Nice, I know how a normal wastegate works, no idea on the external, will have to read up now

[j1v]

A dyno from the last month, stock exhaust collector, internal gate 1.6 overboost, 1.3 hold :

And a dyno from today, the new collector, external gate, 1.9 bar hold boost:

Finally time for the rest of the car to be done (body/suspension/brakes)

yes, it is very impressive. I read back over this whole thread today - its great to have those pics so that we can really see what you are doing. But there is one aspect that I don't understand. How did you remap the ecu. have you purchased a premade chip - or have you made one yourself with an eprom burner / rom emulator etc. If its a "home brew" one - did you find that the info on this forum is correct regarding the table mappings / values? which tables did you change?

Thanks, JimN.

I used TunerPro/Osterich and the info that Wolf66 has kindly provided here for the community.

Nice work keep it up

The camshafts of the Lancia VIS engine are put in reverse - intake -> exhaust , exhaust -> intake

some pictures of the adjustment of cam timing, more will be done on the dyno:

Here are the stock cams vs the ones I have, I would accept recommendations on this topic. We are able to measure the exact angles of the cam timing, so if you have advices, you're welcome

From which Lancia Engine did you take cams?

Are they same as other VIS engines (2.0 16v N/A) ?

Where did you get info about that cams?

thanks for answers,

Yes, lancia VIS stock cams. I took the info from a pdf found somwhere, and also measured them to be 100% sure.

[djsly]

Thank you. You've got PM.

Very nice job. I must ask, are the dyno plots wheel power/torque or flywheel power/torque?

/A

/A

Wheel horse power. Also this dyno is known to be very conservative. A stock 140 hp 2.0 tdi FWD Audi, gives 112 whp on this dyno. There are a lot of awd cars that measure more than 30% losses.

I don't know if I'm gone mad, or what but ... it's time for stage 3

1. Bigger intercooler (again), 600x300x100mm core
2. Garrett GT3076, .63 A/R
3. Eaton m62 from c230 kompressor
4. A pretty simple and effective schema to make ... just need time, luck and a lot of patience.
5. Dual stage water injection 50/50 water/methanol
6. 10mm fuel lines
7. bigger custom SS fuel rail
8. Planned boost - ~0.8 bar off idle, up to 2 bars at 4500k all the way to the rev limit (8k)
9. Planned power - about 450 - 500

BTW, I have just swapped to a Lancia Kappa turbo intake and I must say I love it. This is the best intake for this car. Will post pics soon.

Turbo AND Supercharger? Yes I think you have gone mad. But I can't wait to see/hear about how you get on.

Here comes the summer ... time to think about underhood temps

[djsly]

wicked. Are the VIS cams still inside?

[j1v]

yup, they are still in there

Intake collectors :



Fuel rail with ignition coils on it ... custom short spark cables



New cooler for the steering hydraulics:

[djsly]

looking great.

Is servo steering cooler must have? I'm thinking about getting it out.

I'm not recommending it, especially if you're going to ride the car hard in hot weather. I had bad experience with other cars steering fluid boiling after a few laps, and that's why I upgrade the cooler on this one too.

[djsly]

wicked.

ad6. 10mm fuel lines -

What are the OEM ones?

[K.Kotkas]

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)
