Just a little discussion about the chinese GT45 and the T76 and their best use...
Looking to get a discussion going on the best use (and supporting mods) for each turbo and their compressor/turbine size on different size/stroke engines ...
The GT45 has a smaller compressor and a larger turbine (69/77) while the T76 is the opposite (76/65)
Some of the things I would like to see discussed are...
Is one better for the 4.8 ? (short stroke)
How about the 5.3 ? (longer stroke)
Does stroke/piston speed come into play and is there a difference in exh velocity between the two engines at the same boost level ?
If so, how would that effect driving the two different turbine sides ?
What about cam events...
What would be best for each turbo and engine stroke ?
Which engine/turbo combo would run into back pressure issues first ? Last?
How about which combo would run out of boost first ? Last ?
What about ign. timing ? Do the different strokes and or turbos require more/less timing for a given boost/octane?
And any other questions we can come up with...
RULES......
Keep it civil.
Hard data/facts... trump theory/opinion...
(but l would love to hear everybody's theories and opinions)
Have fun.
