They must of put a new spring in the wastegate, or you have your boxes turned on. Have you tryed stock fueling yet? 40 PSI on that turbo should be pretty good flow and keep the smoke down

 

Of coarse, boxes are on. Still spools to 40psi on the 60hp setting. Didn't try stock.

 

your turbo came with a boost elbow?

 

NO boost elbo needed..... HTT sets the wastegate to 40psi to start.

 

maybe your turbo set at 40. mine I have set on the bench 40 psi and it opens early. has to do with the wastegate size of the holes. did you look to see if you have a boost elbow? our just think you dont have one.

 

People keep saying that but my truck only had 1 gasket per exhaust port (and they are steel). Studs would have made it much more difficult to install the manifold and turbo bolted together!?!?!

Hmmm...never heard of ones on a CR that weren't multi-layered. Most are multi-layered steel.

Studs make it much easier. Aligning those 6 separate gaskets (even single layered ones) is a real PITA. With studs you can do it yourself easier than two people could using the stock bolts.

 

I bought my truck brand new, so I know it hasn't been off. They matched the 6 that HTT sent with my turbo and they certainly aren't leaking! Weird. I put them in myself, no problem. They are kinda "warped" if you will and held in place with a couple of bolts started holding the manifold.

Like I said, no boost elbo at all. My quad box does boost fooling. I could hit 40psi with my stock turbo. So I have always had the fuel to do it. Been doing turbo's a long time on gassers. I have a brand new Greddy boost controller in the box I could put on this truck but it is for my other car just haven't put it on yet.

 

reason why I asked I talked to HTT today and they said they now put boost elbow's on the SS housing because of the reason I stated before the larger ports in the housing open the wastegate up before the pre set bench pressure the wastegate is set at, there sending me one out, I cant get the turbo on stock fueling to go over 34 psi it blows the wastegate open unless I clamp the wastegate hose off, but it will go to 40 psi with the fueling up. I like to keep the boost up on stock fueling around 36 to 39 psi to keep the trailer clean from soot, yes it needs a boost fooler to keep from kicking a overboost code when I have the boxes turned off. Thats why I asked if you looked at the elbow see if it had a set screw in it or not. Thanks

 

I always take lots of pics. That way I can remind myself how much of a pain in the *** it was.....
