You can't see it without turbo off, but it's common, and you will see less power up top than it had when first fitted, and more lag, in my case 2-300rpm more lag.
You would see it if you took the downpipe off, which is less work than whole turbo off. The IHI exhaust housings don't like higi egt's. One of the reasons that I went for something new.
Mine has been like it since "new" though, well at least since first mapped...?
Car still runs quite strong but when mapping it, it did not like too much boost, and timing needed to be retarded to reduce pull back. I had been running it as stock on 95 tesco though, but had BP ultimate in for map.
Running higher boost, it did not really make any more power, whihc was weird, so it got pegged back a bit.
Vagcom at about 1.2bar shows EGTs of 750 to 850 degrees, so it seems within limits, I think the EGT sensor is located on the actual turbo too, not downstream of it..?
Checking cam timing next and replacig the quiet miltek for the slightly noiser one, to see if there was too much back pressure.
To be fair the car drive very well for the boost its running, and I took someone out in it that has converted one running a supposed 1.5bar and 350+hp and they reckonned they felt similar from a lag perspective and top end too...?
Weird thing I notice though is it feels noticeably stronger when colder, (but inelt temps are low at only 30-40 degrees) and on "part throttle" it feels very strong too....in fact, its pretty much as quick through the gears on 50-60% throttle than it is on 100%..? At mid revs at least, 100% gas does noting, not even increase the intake noise, ie suggest more load..?
But this ismy first ca with DBW anyway and have to say I dont like it period!!!
I'll see if I can get a look at the exhaust housing by removing the DP ?
Cheers
BTW John, I saw your inters times on the web, (was not there). was it wet out there and you struggled for traction? Or were your times what you expected?
