I can answer that. Yes it is the 350hp model.

Fab up a compound set up and add a K14.

A K14 would be way too small for a compound setup with this turbo, and so would the k24 or stock t3. It would work well with a Mb t3 turbo though. I am going to source out an external gate .48 ar stage 3 turbine housing to swap on here and see how I like it. And likely get a better waste gate, this one seam to leak too much when its closed. Unfortunately all the t3 turbine housings I have here are internally gated and won't fit my turbo.

Erik and I did some test runs today, got the egt's up to 1600 degrees on a long pull up a hill in 5th at about 5800 rpm, pushin 30 psi in the intake manifold and about 26 in the exhaust manifold. Can't complain about that! We'll see what its like when I get the cam and smaller housing on. I think I am going to hold off on the pump upgrade until I get the airflow a little more sorted out so I can really specify what I need fuel wise.

So what are you doing for the headgasket issues? ARP studs or stretch bolts? Copper HG? Does the cylinder head lessen the chance of HG failure? Is that head an AAZ one?

Ok so found out my wastegate had a major leak, no firering between the manifold and the wastegate... so I need to find one. I made a wastegate block off plate and now the turbo spools fine, full boost before 4500 rpm, it rips! Only problem is that I now get surge at 30psi, but only at 30 psi plus, before that its fine, which is weird, drive pressures are the same as before, maybe a couple psi higher, about 28 psi of exhaust pressure to 31 psi of intake manifold pressure. I can't rev it over 4500 rpm right now because its surging pretty bad, its really weird usually with surge it comes on way sooner than 30 psi... Anyways hopefully I'll track down a firering for the wastegate in the next couple days and see if I still have the surge issue with a functioning wastegate, if I do I'll go with a dual stage boost controller and than I should be good for 35psi which is the limit I want to push on this turbo.
My #3 injector started making a lot of noise tonight as well, I'll pull that tomorrow and figure out whats up with that.

Exhaust pictures in a few minutes.

ahh Dave ,
that waste gate dump maga phone syle thats sweet! how does it sound?
also get back to me about your exaust manifold i'm serious about buying it when your ready! let me know what turbos fit it? i asked in my last post about that but you never said?
thanks Duane

foxracer1 · « **Reply #100 on:** January 02, 2008, 12:35:02 am »

where did you come up with that megaphone? Where do you buy your pipe at? I'm looking to buy some so i have been shopping around. The build looks awesome. Keep up the progress.

935racer · « **Reply #101 on:** January 02, 2008, 01:48:54 am »

Thomas, its 3"

Duane, the manifold fits all standard t3 turbo and larger gt series turbos. I am not sure when I'll sell it but it will be a decent deal, I will want to sell it with the downpipe. Probably will sell it in a month or so. The waste gate dump is pretty loud, I'm not really into open wastegate dumps myself,but my homies here at the shop love them, and I had these 1.5"-3" transitions sitting here for at least a year so... open dump I went! I may go with a dump into the downpipe when I build the tubular manifold however.

Foxracer1, the megphone is just an .065" wall transition from 1.5"-3", I bought 3 of them some time ago for a sanitary job I did,I didn't get them from my regular supplier and what I received was not legal for sanitary, so they have been sitting around since, not worth much to me except for maybe some autmotive use, this is the only thing we could come up with, and the guys have been begging me to run a megaphone open dump so there it is.

Andrew, thanks man.

you have a video or sound clip of the car yet Dave?

935racer · « **Reply #103 on:** January 02, 2008, 02:47:02 am »

Not yet, but in the next few days I hope to have everything together enough for a video, I don't have a video camera but I think my little sister does so I'll see if I can snake it.

Dave that will work perfically for me! my girl plans on getting all this and one of your intakes for me for my B-day and that in the first week of march ! she's a total die hard vw girl! i'm luckey! if you wanna get rid of one of those dump pipes? i still gotta do my waste gate on my stroker truck!
send me a P.M. on what you need for them so the ol'lady knows what she's spending this year!
thanks Duane
