Garrett Gt2860 -9s

[Piggaz]

Made up? Just buy a set of HPI, Midori or if you can find a set, Tomei Series ones. They're all 72 mm internal diameter.

[Guilt-Toy]

yeah made up.. because the engine is in a american spec nissan z33 350z, i can get some big dumps made for it... and it will be pretty cheap here, about the same price as importing a set.

what you think ?

[Piggaz]

Oh right. Oops! Haha

Makes sense now.

[Marko R1]

your setup sounds like fun - maybe run the oem airbox & see how the sound changes? i'd also say its the pods that are making the noise...

ive also wondered whether i should upgrade my hks split dump pipes to the bellmouth type / 3 inch dumps if im aiming for 350awkw with a 2.6ltr & -5s? any thoughts?

i am only running 16psi of boost atm... its summer here and even at 2am its 40deg c....

also i am running stock r32 gtr dump pipes because the hks dumps i had on the 2510 did not fit for some reason.

how much power would these stock r32 gtr dump pipes be robbing from my setup? i was thinking of getting some replacements or get some bad ass 3" ones made, what would be better?? or is it not needed? come winter i really do want around 340rwkw

-9 on an RB30..its very responsive like a NA.

Sounds like a pretty lethal setup. Add e85 to the mix and you should

be well above 340rwkw in the winter. Some people have hit around 370rwkw on e85

on a standard 26 with -9s. Power figure yet to be backed up with 1/4 run though.

Ditch the 32 dumps for some 34 dumps. 55mm outlet compared to a 59mm outlet

on 33 dumps but you can see the inlet of the 34 dumps promote flow that is more laminar.

That and its quite a bit bigger in the middle as well.

Keen to see how this turns out for you

[Piggaz]

What size are your front pipes, Marko?

[R31Nismoid]

Told ya to put R33/R34 dumps of Anth

Or, given it'll be easier - get some made. R32 dumps are no good.

[Marko R1]

i'd have to measure them - veilside full system so they are quite large...i'll let u know later today

What size are your front pipes, Marko?

[r32-25t]

Bell mouth all the way

[Guilt-Toy]

we dont have e85 here, but our 98 is good, real good... 330 - 340kw on 98 will do me just fine.

i am going to get a set of r34 dumps i think.

I'm using HPI dumps with my -9s and making 350kw on 98

So when winter hits in sure you can get there aslong as the rest of the exhaust is up for it

[Marko R1]

front pipes measure 61mm & collector is 88mm - is there an advantage to running larger diameter dump pipes if my front pipes are this size?

my current hks split dump pipes are 59mm

What size are your front pipes, Marko?

[Piggaz]

Jesus, they're tiny!!!

I'd say not, unless you're gonna change front pipes too.

[Marko R1]

thats what she said hey Paul

makes me wonder how much of a restriction my rb30dett was when i had it - that also ran hks split dumps with only a 3.2" inch system & slightly smaller front pipes.

what size front pipes u running big boy?

Jesus, they're tiny!!!

I'd say not, unless you're gonna change front pipes too.

[Piggaz]

Twin 3 inch or 76.3 mm from turbos alllll the way back

[discoPumpkin]

twin 3 inch into the 3.5" catback u mean?

[Count Grantleyish]

^^^ Nope, from memory it's twin 3" all the way.

Racepace exhaust if I'm not mistaken.

[Piggaz]

twin 3 inch into the 3.5" catback u mean?

Where did i mention 3.5 inch anything?

Twin 3 inch from the back of the dumps to the rear of the car.

[discoPumpkin]

far out that r they straight pipes then (no cat)?

I thought u said 3.5" was your old cat back exhaust

Two mufflers, no cats, twin tips... Almost looks standard...

May have, but I've had this system on for close to two years.
