sc61 effciency
What is the effciency range of an sc61 .69 a/r stage 5 wheel? at what point does it start to warm the air up too much? for somereason I thought it was over 35psi but I heaar that its much lower than that.

Re: sc61 effciency (Boostage)
well heres the compressor map if you like to go by that sort of thing-
If you look its 76% efficient all the way up too 3.2bar.. Thats 2.2 bar above atmospheric or app. 32psi of boost. If you're not familiar w/ compressor efficiency's 76% is very good, most compressors we use are about 76% efficient @ max efficiency and only up to about 25psi.. I think you'll get dimenishing returns in power from the stage 5 wheel and T3 exhaust housing before you start getting them from the compressor wheel.

Re: sc61 effciency (Boostage)
Guys,
Stage 5 (T350 76 trim) refers to a turbine wheel, not a compressor wheel. Also, the compressor wheel on the SC61 is from the GT35R. Garrett lists this as an 61mm wheelwith a 56 trim. It lists a 72% efficiency at 2.6 bar or 23.5 lbs of boost with a Garrett .070 compressor cover. Understand that we are using a different exhaust housing and compressor cover all together. You can view Garrett's compressor map from their downloadable catalog which can be found at http://www.turbobygarrett.com. Hope this helps.

Its 72% efficent at 2.6 bar when you use 60lbs/Min flow(approx 600hp) but if you back it down to 50lbs/Min(approx 500hp) its efficiency rating jumps to 78% at 2.6 bar......or Im I reading the map wrong.

Re: sc61 effciency (MadCow)
MadCow,
I wholeheartedly agree with you. Unfortunately, Garrett has made a business decision not to release their T-technology maps to the public. We have to abide by that in order to remain one of their Performance Distributors.
They have, however, released their newer GT Technology maps which can be found on their downloadable catalog on the link I mentioned. My intention is to post all of these when our web site is revamped, which should be done around the fourth of July.
Hope this explains . . .

Hmmm....You were quoting the correct map for what turbo? the SC61? or the GT35R??

Rod if that is not the GT35R compressor map then where are you finding it? The GT40 56 trim compressor wheel isn't in the turbobygarrett catalog.
It still lists the 82mm as a 50 trim which it is not.

yeh haha, but I already found an error in their new catalog.. They list the GT40 56 trim as a 68mm compressor wheel @ the top of the compressor map.. Its an 82mm, they got it mixed up w/ the turbine wheel but they got em right at the bottem in the specs box.
