To4s vs gt30r

[definitiveno]

Yay or nay. Please explain your answer's....

 

[Stapl3]

what?

 

[dalatinromeo]

what?

confused dont know what you are asking

 

[definitiveno]

what?

Is the T0S4 a good compressor housing for a gt30r turbo........

 

[definitiveno]

I realize the gt30r is a mid frame wheel where as the T04S is typically found on gt35r's and the likes. I am wondering if there is any benifit to be found with this housing over a T04E.

If it's free sure go with the bigger cover but if you have to pay extra save your money for something else. I have a cover with the 4" inlet and anti surge shroud and I can't really even tell the diffrence.

Yes there is. I'm in the middle of swapping out my TO4E with a TO4S/anti-surge port because my GT12 (56 trim) was surging due to the size of the SBR bolt-on housing, one might not have this issue with full Garretts.

What's up oldman....

Hey, I remember the other day you were mentioning a possible swap to full garrett. Check out this turbo ive been lookin at....

V-band GT option

Thing looks pretty bad ass eh? Kcuf a SBR housing,

BTW if the surge ports are the only benefit you know the TO4E is offered with them too.....

Thinking about it, can't really afford it yet. Time line all depends on whether this T04S will solve my surge. I have also spoken to Robert at FP about converting my GT30 to a FP type setup, keeping my options open for now.

That doesn't really say anything.

I have been told to never purchase a GT30 BB set up without anti surge ports, I wish I had been told this at the time of purchase so I didn't have to find out the hard way.

I dont' care if you get the biggie GT40-DD Comp housing.. I'm still gonna lay the hurt on you with my whimpy little 50-trim come spring

 

[oldman]

Bring it.

 

[definitiveno]

Bring it.

okay, I think ive narrowed it...

t04e surge ported vs to4s surge ported, ready set go....

Garrett offers the 756021-3 (.60 A/R w/shrowded port) as a bolt-on for their GT3071R (71mm compressor). This looks to be what FP uses for their GT-30 based turbos (machined to fit of course)

My FP3065 would surge in 4th gear if I was going from a lower rpm rolling start. So don't count on it completely eliminating it. Most of my time was spent in the 24-25 psi range. It's a little over that where you end up hitting that surge part of the curve.

I'm sure it will help, but I wouldn't count on it eliminating your problem completely.

I don't know about your car or even that the 3065 came with the kind of surge ported cover we're talkin about but the surge that you get doesn't come on at high psi it's at partial throttle driving.

Yep, mine comes on between about -5 to +5 psi.

I'm refering to operating to the left of the surge line. The 56 trim "gt40" compressor wheel has that hump in the map on the left on the surge line. When the boost is high enough to be in that area of the map, I get surge from the gears with more load on them. Seems to behave fairly close in practice to what should be expected.

Here's an example of what the ported compressor covers are supposed to do, as I am understanding it to work.
