How much you can get with 7A cams?

Ah okay, did not know you were using E85.
That's a different story then. Good luck with finding a cure.

What do you mean by exhaust exducer? The turbine exducer from GT3076 is 55. The major turbine diameter (turbine inducer) is 60mm.

At the compressor the Inducer is minor diameter and exducer major diameter. At the turbine the opposite: inducer major diameter and exducer is minor diameter.

Right forgot about this
In comp terms the 1st number is compressor inducer the 2nd is turbine exducer
Gt3076r is a 5760
Gtx3076r is a 5860
Gtx3576r is a 5868
Gt3582r is a 6168 ( actually 61.4 rounded down )
Gtx3582r is a 6368 (actually 62.5 but rounded up)

I will check my precision catalogue for that product

Did you try different plug gaps?

ik27 Denso / coils , close in specification tu 034 HO , i spoked with the sparktech guy to try his evo setup in I5 :-)

Please please please get rid of the denso's I have seen more engine failures then I can shake a stick at because of them. It would be a real shame to see all that work written of unnecessarily.

I would not be surprised if they are the cause of the missfire.

For the 3rd time. Turbine exducer on the GT3076 is 55mm most probably for GTX3076 also.

Thats odd the Pavalova RS4 runs these.

What spark plugs do you think are better ? and if the new coils are not good enough i try to reduce gap, according to sparktech coils are good for 700atw on 4cylinders and e85 !

No it is not, you know better than the garrett website?

Actually Garrett site says turbine wheel diameter 60mm, so the exducer is propably smaller than the overall diameter.

60mm and trim 84 (Trim = Inducer2/Exducer2).

Nope I have the garrett catalogue the exducer is smaller then the inducer I'll post the inducer size when I get home
At billman those sites are wrong depends what you believe the official catalogue and website or aftermarket retailer

[Billman]

ok...I rest my case....

Garrett always states max diameter and trim!!!

[Thuppu]

Ok lol, Jamo, seriously, what mushrooms have you taken today? Or is it me?

[Chriss@S2]

Ok, because it is weird that you are getting this problem at 550nm.
Both brand new original coils, as well as 2.0TFSI coils can easily handle much more than this.

Have you tried increasing dwell time? Maybe it's too low? Or maybe you have a big voltage drop?
Also, 2.0 TFSI coils at 3ms dwell should not misfire even at 750nm. I have not tested more personally.

I hope you get it sorted. 550nm is just not the torque to get misfire issues on this engine, unless something is wrong with ignition system.

Hi,

what kind of 2.0TFSI coils do you have, what number on the coils?

there are many different avaible
