You're making the car more auto-x friendly it seems? |
I'm just trying to get the full potential of out a stock motor <250rwhp setup. If I can still make 230rwhp, as I'm at now, why sacrifice the low-end I know I can gain?
the auto-x benefit would be nice, as well as the overall experience. I only HDPE ever once in a blue moon, so it wouldn't really hurt me there. But, If I didn't have a stock motor and made it to the track more, I probably wouldn't bother. |
You should chat with Emilio. I know he had a water/air IC for a bit with the idea of increasing throttle response.
I'd like to do a real datalog and figure out how much that matters. Put some sensitive pressure sensors along the intake tract and find out what really does what. |
I'm not THAT considered that I'd go with a a/w IC. my new tube and fin already shaved off close to 400rpm from my spool.

You still want that T3 compressor I Have?
What I've got IIRC is a 40 trim.. Pretty tiny... |
I gotta go back out and button it up later today:

Why are there two vacuum ports on the wastegate can?
|
to make use of pressure differentials.

Just pausing to notice that was Brain's 20,000th post.
Wow. |
Nice! It looks good. Go to home depot, get some aluminum tape, it's like $5/roll. Excelent stuff, wrap those heater lines in it.
If you want toi go all out, get that, and the 'water heater/pipe tape', also aluminum, but with a thick layer of foam. I stopped losing hoses/wires when I wrapped everything in it. Super cheap, stays on, and works better. The second fitting is on the far side of the diaphram, if you don't want to reference atmospheric. |

Wow, you went to a manual rack.
|
That exhaust wrap has been holding up for more than few years now...
yeah the new car I put together has manual rack, it's so choice. |
I finally got a chance to run out and finish bolting it up and to check for leaks. All seems well, i think i wired it wrong cause I only got wastegate pressure. I need to fool around with it later this evening or tomorrow to see how it reacts at 13psi.

Before I removed the first turbo I made sure to take a good 4th gear log of my spool. Starting at 2600rpm or so when I hit WOT.
This morning I went to the same stretch of road and did the same. This should have given me the best comparison of the two. I'm only hitting my target boost about 100rpm faster vs. rpm, but the interesting thing seems to be the rate of RPM increase. When I overlay the two the rpms increase faster. I even went as far as to make sure the ending RPM was exactly 4K so the scaling should be more or less spot on. Looking at the two I even hit WOT with the new turbo 100rpm less than the new one, yet my rpms increase much faster. This makes me think I'm making more torque lower just like I wanted. I can still play with the timing and wastegate rod to try to increase the speed, but this mornings drive I could tell the power delivery was much smoother and there was less of a torque surge when the turbo made boost. My duty cycles are a lot higher with the same AFR during spool, so that for sure means more torque. http://www.boostedmiata.com/logs/new...comparison.png |

Hell Yeah!
