I actually think the t66 map fits a 6.9 or 7.3 better. They both flow about the same max, but the pressure ratio you need to force the air in there puts you off the map on the 362. Turbo lag might be an issue, but as far as the maps go, I like the t66.also remember not all turbos are created equal. There is more to it than the wheel sizes.
S362/64/66 turbos and Holset HE series for instance out class old school technology like T66/T70 and the stock turbo's stock/modded.
a schwitzer 62/65/14 would be a pretty good turbo for pump/sticks mods I think.
A T66 would spool dreadfully slow.I actually think the t66 map fits a 6.9 or 7.3 better. They both flow about the same max, but the pressure ratio you need to force the air in there puts you off the map on the 362. Turbo lag might be an issue, but as far as the maps go, I like the t66.
I am looking for 2 things....The ats turbo (h-3trim) will flow ~50lbs/min
the 60-1 to4b flows ~60lbs/min (about the same as a 7 blade hx35)
the 362 we've seen flows ~72lbs/min
Are you trying to be more mild than the 362?
what about bone stock.....how would these do?Honestly, Id look at an HX35, and try and find a 14cm housing for it. They are common, easy to rebuild, good turbos, And for a mild build, they will be just fine. If it wasnt for me finding the deal I got on my turbo, Id be running an HX35 right now.
The s362 looks like it would run great at 25psi, and even more efficient at 20psi. I'm glad someone is reading compressor maps instead of just saying hey this spools good on this it must work fine on this. It's not that easy. NMB2 I assume your gonna have yours run to 35psi? What vehicles did the s362 come on? Never mind those are absolute pressures so you would subtract 14.7 from them.
That is very true. But since it is a Garrett, aren't there any turbine housings that will interchange with it that are better? That could be an easy possibility.You can have the best compressor on the planet, if the hot side sucks, the turbo isnt going to work well. The stock turbos for these engines have pretty crappy hot sides.
Thanks for the info. I know i got all my turbocharger math all messed up i have it written on Favorited somewhere. Thanks it helps me visualize it non the less.If you look along the left side of a compressor map you will see the pressure ratio values. To determine where 35 PSI factors in that scale you use the following formula 14.7+boost you want to run / 14.7= pressure ratio. So we take 14.7 add it to 35 psi and get 49.7 and we divide that by 14.7 and get 3.38 so our pressure ratio for 35 psi is 3.38 so find where 3.38 is on the map and mark it like I did in red.
