Audi S2 GT3076 "made in France"

[prj]

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

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

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

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

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.

Stock 3B ignition? Looks like it.

[yannS2]

Yes stock

[Avantus]

Isn't that a bit dangerous at those power levels?

[Billman]

I think he got too much and he is just new in the forum.

The car looks very nice but with a GT3076R turbo we see much better spool and we have many examples with them.

4th gear 2bar overboost and 1.76 till 6800rpm.

Thanks Bilman

I got 2bar from 3076 at 4500rpm - 82 ar - CatCam - biggest for hydro, no head work...

maybe the dyno has wrong setup.

Compteur Audi RS2 :

i'd have a look at the throttle cable, looks a bit loose to give a decent response.

[rs200]

did you change your wastegate spring? what about connecting rods?
and you still have stock 3b ignition??? you are very brave my friend.
if you will need new engine block.. contact me.. I have it few for sale

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.

What turbo are you using?

I'm building a stroker and using a Precision 6262 which is rated at about 700hp
