Would an A/R .85 housing gain me anything?

[V6POWER]

Would an .85 housing work with my combo? See sig. for combo.

If you run striclty 1/8 mile tracks you likely won't see much gain, possibly a bit. In the 1/4 though you'll see some mph improvement on the big end.

How much boost are you running? I wouldn't change it unless you were clearly having a back pressure issue.

 

[V6POWER]

I run 26-27# boost.

I ran a 6265 with both a 85 housing and a 63 housing. Running at 26-27lbs of boost with ported heads the trap speed was basically the same. Actually the 63 trapped 1 MPH faster but maybe the conditions were different. This was trapping at 125-126 to give you an idea of where I was at. The spool up was quite a bit slower with the 85 as well.

Great Info as Im looking at a 6265 now and was going to go with a .85 housing looks like the 63 is better

 

[V6POWER]

Thanks for all the feedback. I will stay with the .63 and find another use for the money I saved.

 

[Mr.Spool]

you really need to have the boost way up there for that .85,always slowed down and lost et with the .85 vs .63 on 49,62/65,and even on a billet 64mm strim.the .63 pte and tnetics .63 have been 9's.im currently running mid 10's and track tested a mph loss and et loss when running the larger .85 housing

 

[V6POWER]

Mr. Spool--Thanks for the additional input. I am staying with the .63.

Hey Jim, You can always get some suspension stuff to lower that 60' a couple tenths :biggrin:

 

[V6POWER]

My 60' isn't too bad. I still have a pair of lower control arms in a box from two years ago, that I need to install.:smile:

Order a .85 after you go 110+mph in the eighth.

 

[V6POWER]

Order a .85 after you go 110+mph in the eighth.

That means I will definitely stay with the .63, because I don't see me ever going 110 in the eighth.

were you running through the exhaust or cutout?

Was this through the exhaust or dump?

 

[Sweet6]

At the track dump open with both.

 

[turbo96max]

At the track dump open with both.

how do you think the .85 would have done through the exhaust ?

 

[Sweet6]

Maybe spool a tad slower. But switching between the two housings was night and day difference. On the street it was so much more fun to drive. Roll on boost is night and day better. At least for my setup.

 

[Mr.Spool]

Was this through the exhaust or dump?

wow old thread, but at that time I tried both.ive gone a lot faster since and going through a good exhaust isn't giving up much to an open dump.

 

[TT/Ameasap]

One thing that I learned was going from a ported iron and .63 to ported aluminums and .85 spoolup is the same.
