Hi Flo Gt-ss Turbos?

[harks]

Has anyone ever considered getting this done? It occur's to me that a turbo option somewhere between the -9/-5 range would make ALOT of people happy. And seems like it would be a perfect match for a 2.6.

I know some people will say its a waste of time and just choose from an existing turbo. But i have a set of GT-SS's where 1 needs a to be rebuilt, and currently have -5's on my car, I enjoy the -5's... but they do lack transient response and are a bit slower to get fired up. So if/when i decide to forge my engine its a perfect oppertunity to swap them out..

My thought would be turbos that could do 350kw on 98 (with all required supporting mods). On a 9:1 compression bottom end it would be a wicked street set-up. Or even with a 2.8 bottom capable of 360kw+ with full boost from say... 3200?... ballistic?

thoughts?

I know someone with something very similar in the pipeline currently

I'm interested to see their results then!

Isn't that what Racepace does? Or something similar.

Current setup with -9s 350kw 98 stock compression (maybe lower) built engine etc

Setup in the build currently as did a ring in my engine (injector wiring chaffed)

2.6 9:1 compression nothing lower flex fuel setup and -9s

hopefully will be all done in 3-4months

Will post results when I have them should be fun hahaha

Andrew Hawkins has got hi flowed -7s in his car

What was the power result of that car? They didn't mention in the video.

Same damn good results. The 6speed getrag they do is awesome too.

Hawkins turbos are more resembling of a -5 now than a -7. Hard to directly compare to your average joe with of-shelf items

You knew someone that had it too, long ago now though lol - Me

I spoke to GCG yesterday asking about highflowing my -7's, he said that just results in a -5. Is that right? My understanding of watching the motivedvd vids is that the inlet size is smaller than a -5 but the comp cover is machines enough to fit the larger wheel?

That raises an interesting question... if the machining was done just to fit the -5 compressor wheel, with stock inlet diameter, would that give higher too end without -5 lag (obviously not -5 power, let's say a midpoint) OR would it be -5 lag with no real benefit because of the heavier larger moving parts with a restriction.

I would think it would be the latter?

Depends what you mean by hi-flowing... Or "making a hybrid" of the two.

Similar process, different end results. Read thread I linked above and you'll see there is differences
