One of the best MODS I have done

[blown 944]

I was not going to do this b/c I was looking for a Tial w/g but I went ahead.

I made a dual port stock wastegate. I did it by tapping the bottom side of the diapham housing and installing a 1/8" pipe thread fitting with a 5/16" nipple.

I also used self tapping screws to seal the 4 holes.

I also used a 3/16" tall piece of copper tubing to seal between the diaphram housing and the valve housing.

I wasn't going to do it b/c with the turbo I'm using (T4 .58 ar p trim wheel (big) ) I figured the crossover pressure would be minimal. It was to an extent.

what I had before was that my MBC was set to 22 and would taper to 20 at redline.

I did the mod and went for a run with the MBC bleeding the same amount and it shot right to about 27. Needles to say that was a quick one. I am not looking for that kind of pressure yet .

I reset my MBC and now it is set to run up to 24 and holds 22 rock steady. It builds quicker too.

It wasn't as necessarry with my setup but anyone that is using a stock W/G even if it has some shims in it will definately benefit from doing this. Especially if you are using a K26 turbo or any small hotside turbo.

Just thought I'd share

No I don't take too many pics of teh small stuff.

I did however just get done with my dyno runs about an hr ago

I made 410hp and 445 pound ft of tq

I now have to convert the files using a PC b/c the program is not formatted for MAC

I still have teh nitrous to go but I have a coupel of other things I thik I shoudl do first.

I'll post a thread about the whole thing once I get teh dyno sheets into a Jpeg format rather than the drf files.
