We have somewhat of the same build, so yours should be faster than mine if tuned correctly.

I ran 26# boost and 20* timing on the run in my signature.

so 1/4 that like 10.7 id imagine. a lil better 60' and i could on a good day probably go 10.5?

bison i was talking to dave about my converter it seems really tight and takes for ever to build up to boost hes going to loosen it a bit but he also told me to talked to you about getting a garrett housing. how much and do you think this is a good thing for my setup

 

[bison]

It depends on the goals. I wouldn't personally use a Garrett .63 for quicker than high 10's. It's not enough for that turbine. Loosening the converter will increase flash stall and hurt quarter mile performance potentially. If you aren't planning on running it for all I'd consider loosening the converter and the Garrett .63 ex housing. The housing itself will spool it 200-300rpm quicker. PM me about the housing if you want one

i plan to give it all shes got at the track so mid 10's as you stated it potential. so if i wanna do that just loosen the converter if i read that right.

You never posted any data that would make me rec loosening or tightening a converter

i am loosening it because it wont build boost the other day i was at the buick meet and standing on the break in a parking lot and standing full throttle on the gas it took 9 seconds to build 4psi of boost. i have a log on this sight ill see if i can find it to link it so you can see

Checked for leaks in the exhaust?

[bttwracing86T]

yes all leaks had been fixed.

 

[Turbo Negro]

Something is definitely not right. Even with a cracked header, tight converter, & the larger ex. housing all at the same time, I would imagine it would spool to over 4lbs in less than 9 seconds!

How much boost can you get while driving (not braking) at WOT? And how did you verify the WG?

I doubt the converter is your problem if the rpm is up around 2800. Check your swing valve assembly. Had plenty of problems with after market crap lately

What is swing valve assembly

Your wastegate puck may not be completely covering the hole on the turbine housing. Unbolt the downpipe and post a photo of the exhaust mark on the flapper/puck and the turbine housing. I had this issue on 2 or 3 turbo buicks.

 

[bttwracing86T]

i couldnt get a good picture but i was able to see marks all the way around the housing where puck sits and all was covered ...

 

[jasjamz]

Can you post a pic of the Puck. It needs at least an 1/8th inch to seal.

[bttwracing86T]

ill have to get the downpipe out its stuck for some reason ill try to get one by end of the day

 

[bison]

The edge puck could jam on the hole and not seal.
