The problem is that the thing is loud even with the opening in the grill.
After running the Rabbit around for awhile with just the turbo elbow and a short (12") pipe to keep the soot out of the engine bay, I finally got my exhaust put on. I loved the shriek of the turbo, but the noise was pretty loud, so I ordered a Techtonics 2.25" exhaust with the Magnaflow straight through muffler. Now that it's on, I can't believe how quiet it is. Just a little turbo whistle in the backround. Almost too quiet. Maybe I should put a cutout in the downpipe. :twisted: Then I could have my cake and eat it too.
I just did the same conversion on my Rabbit with the Magnaflow straight through oval type muffler {center inlet and outlet}, I was afraid it was going to be pretty loud too and it's twice as quiet as the N/A engine was. It's too quiet like you said and you can hear all the other little things that are better not heard :lol: PS. What have you seen as far as boost with your T3 and EGT's as well. When I put my everything rebuilt engine in with a Garret T3 Stage 1 turbo from MJM Turbos I haven't seen over 6 pounds of boost yet and the EGT's would climb to about 1350 with the stock T/D pump on it accelerating fairly had through the gears. I had to take the T/D pump off waiting to re-bush and seal it because it leaked and was hard to start, long cranking times but ran just perfect oherwise. I have way less power now with the N/A pump on it but the EGt's came down a good bit. I haven't messed with the wastegate actuator plumbing yet. I have a feeling though that the turbo might actualy be too big though. It is just a rebuilt T3 but with a what they call a stage 1 conversion to a larger compressor wheel, how much bigger I don't know but it is definately bigger just looking at it but I didn't get any specs on it .like a dumb ass when I ordered it.
yikess 1300 LOL keep an eye on that thing.. all you need is for one day to look over and see 1500 and then as soon as you see the gauge... BANGG lol
Good Tip!! The engine i'm putting the turbo on is brand new, but when i started the rebuild the intake valves were, as you said, the first third of valve lift was just to get past the crud!How many miles does the engine have on it before the turbo kit?----How many miles have you put on it with the turbo?

When it was an overfueled NA the EGTs were higher than 1300 for minutes at a time during climbs, and the engine has performed pretty well for over 120k miles like that for me, and many many miles before for the PO. VW states that the maximum turbine inlet temp for the TD is 820 C (~1500 F), so I'm pretty sure the NA engines can handle a brief transient (2-3 sec) of 1300F without issue.
