Well, a few more results after last week’s dyno of 767awhp/758awtq on the MTC Stage-2 turbos. Swapped in the MTC Stage-4 turbos and put down 842awhp/763awtq on the rollers earlier this morning. Same boost pressure, same setup, no changes.
So here’s a quick comparison of various TD05 setups on my car using the same dyno each time.
EVO3-16Gs: 688awhp/679awtq (27psi race gas)
FP 68HTAs: 740awhp/762awtq (33psi race gas)
MTC Stage-2: 767awhp/758awtq (35psi race gas)
MTC Stage-4: 842awhp/763awtq (35psi race gas)
Power on the MTC Stage 4’s lagged behind the Stage 2’s by about 200-300rpm until 5000rpms where the Stage 4’s started making a lot more power. A pretty decent trade off I think.
Very minimal changes between the setups. Please remember that peak numbers aren’t the big picture, the overall power under the curve is what’s more important – I’m happy to say overall, each of these combinations has a nice powerband depending on what your specific goals are. Higher boost is attainable, but we realized my AEM MAP sensor is preventing us from doing that at this time. I doubt I will upgrade the MAP sensor to run more boost. I plan on addressing a few other shortcomings instead.
Right now, I am facing a few bottlenecks in my setup that seem to be holding back the potential of these larger turbos, especially up top (6500rpms+). We’re indentifying them, and hopefully will address some, or all, of the potential bottlenecks then re-dyno again for comparison. Just depends how motivated I am to do it along when determining potential gains versus associated costs. After the car going sideways while drag racing and hitting the cement barrier a few months ago, I’m still recovering from those repair costs too, grr.
Stay tuned….. I’ll try to post up more numbers in the next week or so.
