.84 split pulse

.81 single pulse

id go .84

0.81 suits the 26 perfectly so will be abit small on a 3L i reckon....

Hey StageZilla,

What is wrong with the .84 split pulse? Why is the .81 far better?

Just really interested as there have been a few threads about these turbo's in respect to response. R31Nismoid said these turbo's may be able to make the 500rwkw mark; what exhaust housing would you use for this application? And will it loose its 2530 type response?

although i dont remember outwardly saying 500rwkw anywhere  :)

Yea, you did. Quote below.

With fuel and boost 700rwhp i think it would get close too with more boost. I dont think pulp will achieve it... but you never know

It was the post about the TO4Z results.

I used the "SEARCH" button. You must be proud of me! :P

i was only going by the hks t04z's sorry, they only do the 3 housings, 0.64, 0.81, and 1.0 i think, and as r31nismoid said it depends on ya manifold and whether it is split pulse.

cheers

Just to tack on to the end of this thread, does anyone have any experience with the Garrett T04Z with the 0.96 exhaust? I assume power would be very similar to wrxkilla's T04R dyno graph from a few weeks back, and same sort of lag/response?

Talking about a 2.6L too, not a 3L :)
