I am getting ready to do a 6.0L swap in my truck and I am currently running a .82 exhaust housing on my MPT70 with my 5.3L. Should I stick with my .82 housing or would a .96 housing be better for th 6.0L? I have a .96 housing sitting in the garage that I could throw on it but I wanted to see what you guys think. Oh yeah, this an STS kit so spool time needs to be considered. Thanks

 

Do you want bigger numbers, or better street performance?

 

I like dyno numbers but I am looking for track and street performance. I'm trying to catch up with you but you keep getting faster.

 

Haha, I have a set of hot pipes just for you, I'd keep the .81, but that's just me, who still has a .68 on my 5.7 front mount. But I am going to put a .81 on my front mount to see if I can get a little more top end out of it with out affecting my super fast street spool to much.

 

I would love a set of your hot pipes. Can we work out a trade to get your old STS kit back?

 

Hell no!, you know how long it took me to find a sucker to pawn that thing off too? LOL

 

Yeah, lucky me. LOL I actually love the STS kits but they are a pita at the track. The last time I had it at the track I had to let it run the entire time I was in the staging lanes and then do a massive burnout to get the turbo hot enough to spool on the line. On the street it's a different story though and I love hearing the turbo.

 

Well if you have both housings why not try em both?

 

I believe the MP T-70 that KB has specd for me will be with the .96

 

i don't have a t-70 but i do have a p-trim wheel on my turbo and a .81 a/r and it falls on its face around 4800-5200 rpm. is it possible that its just valve float? i mean i do have stock valve springs and running 10psi. i'm just agrivated everone seems to get way more rpm out of there smaller a/r's than i do. WTF
