If the photo was taken 10m further on the the arrow would be pointing at the car!! (shame, you'll have to come back and do it again!) but its still a great photo.

Looks like you're having a lot of fun with your car.

evilC September 9th 2009 10:19

Exactly like that! Brilliant!! (I have noticed that the Dutch are travelling on the wrong side of the road{again}! lol I must try that when I'm next in Holland - oops)

Got a smoking deal on a slightly used 'bigger turbo' :D
Hope it gets here in one piece soon...
Its not one of the usual turbo's that are being used though..

Don't you have a bigger picture:eek:

Paul:;)

Sandeep September 16th 2009 15:55

Judging by the size of that picture, it IS a big turbo !

GT3076R CHRA ? :rockon:

When is it being installed and when is the dyno booked ? :D

Yep, I guess I have basically the same turbo as you then? :cool:

Probably an over winter job and fitment is likely to be not as easy as I anticipate (as usual..)

The Blouch DOM3 (or GT30R if you like) is underway and going very well. Almost too well...
Getting the right orientation for the install under the bug meant disassembly. Always scary as you don't know the part and taken apart a perfectly fine almost new part is somewhat counterintuitive..(well...:rolleyes::lmao:)

Here you can see that the intake is just passing the cupstrebe and the tranny/starter. The wastegate even has more room on this one, but one of the alu threads for fixating it to the housing is almost stripped...Have to wait and see if it holds.

So, the IHI VF34 is now for sale ;-)

Nice find, I see lots of power in your future!!! How do you think this one will stack up against your current one for lag?

Jason

Its a 2.2L it should be pretty wicked, I'm guessing 3K to 3500 for spool start time... I think a GT30R has ball bearings...

Ah, yes, good question, which I wonder myself also. Actually, I would ideally have wanted the GT3071R for even a little lesser lag, but this one came along..

Kulein: the former IHI VF34 had ball bearings also! Theoretically spool should be (much) later, but in reality I think it will not make that much of a difference. A little later spool is not neccessarily a bad thing! I actually like spool to be a little later so your not on (back)pressure all the time on the highway and overall back pressure (=high EGT) is less.

About 1 bar boost (14.5 psi) at 3800-ish rpm would be excellent for me. Right now I had 1 bar at 3300/3400 rpm in 4th. The old turbo had a nicer (for me personally that is) spool on the 2 liter.
Purely track driving, spool of the VF34 was better on the 2,2 I think. In 3rd coming out of a corner at 3000-3200 rpm, spool came in really nicely an drelatively gentle. That last thing is cam and tune (wastegate ecu control) dependant as well of course.

Waste gate location
 
Hi Walter, please be very careful of the waste gate location. If somethng hit it/bend it, you could over boost.

kuleinc October 15th 2009 17:46

I think a lot of people use the GT30Rs here for 2.0 - 2.2L engines, with good results, but these aren't Aircooled VW engines, so who knows...

Heat on the outer CV could also be a problem especially when stationary after a power run and its glowing red hot:angry:. You could kill two birds with a heat/impact shield over the waste gate and exhaust side of the turbo.
