Audi S2 GT3076 "made in France"

You should spool way earlier with .63 also why are you running 7a cams? At this power level run stock cams!

Shock, I agree with Jamo for a change.

Because you have 0.63A/R, you already chose to have it kick in the mid range over the top end, so stock cams are a much better synergy with the turbo.

It's just On the road, my car spool at 4000 RPM.

Audi RS2 with GTX3076 ar82 is not my car , it's just example the car on the dyno, today.

My car is Audi S2 with GT3076 ar 63

GT3076R 0.63 A/R should reach full boost at 3800-4000 RPM in 3rd gear.
If it's not, something is wrong.

Look, on this turbo, 0.82 A/R you should have 1.6 bar at max. 4000 RPM.
You reach it at 5300 RPM.

Fact is, something is really wrong with your car or the dyno.

My car is good but my ECU is a problem....
So my boost is 1.6B and no 2 Bars....

There is something really wrong with your spool up.
I have a stroker and 700hp capable turbo and it spools faster than your gt3076.
This log is done with 3rd gear.

[Avantus]

That is a really narrow powerband imo?

At what Rpm should this turbo spool normally?

Something is really wrong with your car or your mapping, or that dyno.

Example today Others Cars : Audi RS2 2.2 GTX3076 AR82 - Wagner RS2 EVO - 7A cams Boost : 1.6 bars

[yannS2]

I ask if the camshaft are in the correct position. It seems that it spools too late for a GT3076.

Position stock. Low boost => Spool too late

[yannS2]

off course you can

First test and four in the car.

Today, it works much better

with 'proper' ECU mapping you can get it boosting even later

hahaha
