manifold is split pulse,turbo specs I dont know as it was built by gcg.graph will show the boost comes on without too much lag.

nice rig dude

How about a close up shot of your exhaust manifold. Looks like a nice setup

best photo that I have of the manifold.

cheers geoff

Rapidute,

what boost are you running around three and a half thousand rpm and boost in the top end?

Geoff,

Have you got a boost graph to go with it? Is that with pulp, or race fuel?

There are around 9 different exhaust housings to go with that turbo, so quite a few possibilities.

Looks good and very strong midrange, although I usually prefer extractors for enhanced top end as well.

Are we talking split pulse as in the way TRUST / Greddy do a split pulse manifold with matching exhaust housing inlet?

Just wondering as Ive never seen a Garret split pulse housing.

Or is this manifold just 3 runners fed into each side of the housing's flange?

I dont think there is room when making a "log" manifold for this runner arangment, all the Logs Ive seen, made, and used have just been 6 into one kid of thing...

ETM, you know what I mean yeah?
