Re: Garrett GT series turob maps (TurbochargedSER)
The 60-1 compressor is based of off T04B, isn't it??? And the GT series turbos are based of off the T04S. Am I confused here are is this information correct? Anyone care to verify this.
Thanks.
Thanks.

What is this crap?
Re: Garrett GT series turob maps (VaporTrail)
i say that based on my flow calcs plotted on that compressor map. i am not taking into consideration IC or piping losses and i have no idea what exhaust a/r its running, but the cold side looks spot on.
only reason i mention this is that the .50 and .54 trim compressor wheels looked better suited to a stock b18c1 but everyone seems happier with the .57 trim or larger.

60-1 wheel has a 2.32" inducer and 3.00" exducer. Exact same specs as the 60 Trim GT30. They do offer the GT30 with a 48, 52, 56, and 60 trim compressor wheel.

Re: Garrett GT series turob maps (TurbochargedSER)
Thanks for the comments, but it still seems (from my calculations https://honda-tech.com/zerothread?id=329711 ) that the T04E Super 57 with the 2.29 Inducer and 3.2 exducer is a better match up for the close to stock bore ITR engine. So which GT turbo would be similar to this setup?
thanks.
thanks.

Re: Garrett GT series turob maps (DRAGLS)
I would agree with you, based on this map that what it seems. I think that there is more to it if someone would car to explain my original question as to how do a/r's affect the map.

a/r's don't really affect the air flow, they determine what rpm range the turbo will operate in it's efficiency range

I am confused more about the 60-1 than ever before.
I posted about the 60-1 a while back...
https://honda-tech.com/zerothread?id=316783
will you help me?
for some reason...
By calculations using 85% VE, It seems that only a 2.8 litre can use a 60-1. How can a Honda use it (without the aid of NOS)? That map above is straight from Turbonetics for the 60-1 compressor.

Maybe because honda's are operating at a much higher rpm than any of the other cars around. mostly 7000 rpm while hondas can rev up to 9000rpm even 10000rpm

Re: Garrett GT series turob maps (Quick 200k Mile Motor)
I may not be correct, but I belive that honda dohc vtec engines have a lot higher VE than you specify. Take a look at one of my earlier posts in this thread and you will find a link to my calculations, you will also find the numbers I have used. Maybe this will answer your question. But I do agree with you that the 60-1 does not seem to be the most optimium turob for a 1.8L engine even reving to 9000rpm. This is why I had the question about the effects of ar and trim on the map.

Re: Garrett GT series turob maps (VaporTrail)
Would you mind giving an example. It is quite hard to visulize what you are stating. Thank you.

changing a/r is just messing with when the turbo will get into it's efficiency range, sort of a way to customize the turbo (a little bit) to the flow characteristics of your motor

Re: Garrett GT series turob maps (Prod)
Dont trust compressor maps they are good calculations but sometimes u just have to test out a product to see how it will work. if everyone followed compressor maps I think we all would be running strait T3's on our lil 1.6 and 1.8's.

Re: Garrett GT series turob maps (DIRep972)
yup.
we have higher ve's. higher comp..rev higher.
and the fact that MANY people have been using them and they are known to work!

Re: Garrett GT series turob maps (Prod)
Thanks for your inputs
So, Turbonetics compressor map for 60-1 is wrong, stock Honda has more VE than normal, and A/R moves the sweet spot (efficiency range) up or down.
I'll take a look at your earlier posts about VE like you said. Right now Im thinking 85% VE for stock LS head & bottom end, and B16a head & bottom 90% VE..
