but seriously wasn't expecting an 11% bump in TQ over my last time to this dyno at the same boost level.

Great numbers scott!

Are you claiming your 11% torque increase is due to sequential injection? What is your duty cycle at the largest torque difference?

It's quite interesting how similar your turbo looks/measures to be to the garrett unit but a big difference in performance.

Same boost, same setup, like I said, only major change is running seq. fuel and a tightened timing belt . It's running the same spark map - just a lot more fine tuning.

disregard the AFR readings, my first run was majorly rich, and it seems my sensor is a good 1 point off from their readings...I was shooting black smoke; I need to recalibrate and figure out why, this happened last time I was there and could explain my sub-par MPG.

The high intake temps might have effected the top end output negativrly, but probably not by much. I need to see logs from others of the day to see if they had the same high AIT issue if it wasn't just an undersized fan being used or if I really should step up to a bigger intercooler.

It was a 60-65*F day out during that pull, I hardly see over 120*F on a 90*F day going through gears in boost.
Just check your Gair # from the datalog, or compare your pw at a particular rpm when on the road, compared to at the dyno. I did this, and found that for a similar ambient temperature, the pw on the road was 12% higher than at the dyno, for the same afr and boost pressure. This is because the intercooler roasts at the dyno. I would expect this to be true for all boosted cars, but your temps are much higher than I have ever experienced (and I am running higher boost), and at your torque peak, your temps look to be fairly low.

Disclaimer: This is my opinion, based on numbers from my car only, and although I went to 3 different dynos this year, (2 mustang and 1 dynojet) this may not be representative of the community as a whole. ie -I welcome your comments...

Your numbers look very good. The car must be a blast to drive.

These results are making me reconsider about going with gt28 chinacharger. And the price difference is a plus.

Should be more fun with a 1.8

The only changes from the dyno in March to the dyno in Nov were this:

  • Tightened my timing belt. (My tensioner was loose and TB had sloop)
  • Replaced a 90 bend & 4x9x18" muffler with a three 90 bends & a 5x11x22" muffler. So I actually added restriction.
  • Added MS3X and rewired for Seq. Injection and Ignition. (I was running wasted spark on both pulls.)
  • Tuned Injection Timing Table.
  • Replaced Transmission

Everything else was the same, including the spark and boost map.

I forgot about the tranny swap, I did that at the same time I did the exhaust. That could have easily had an effect on the power output, it was whining like crazy before I removed it and it drives much better since the swap. I pretty much killed my rear, tranny, and block in 2009 at the last dyno day up in DE. I drove 2 hours on a rear end with no fluid. The car never felt the same after that, my transmisson started howling at me and the rings pretty much let go on the dyno. This is why I had poor results with my custom Intake Manifold. I ended up selling it to pay for a new rear end and eventually had to replace the block; the trans was the last piece of the puzzle.


Whatever the case, I'm pretty happy... I would just like to see better low end still, but I simply just need a 1.8L.

Great results! Thanks as always for sharing your info, I hope to get mine to the dyno sometime soon. I am also running sequential fuel injection thanks to the DSM ECU that's calling the shots and have wondered if there's been any power/efficiency gained from that change.

I am running the same turbo and I have the most incredible urge to throw a bigger wheel and compressor housing on it over the winter to see what would happen. I'd hate to lose any of the low end though, it makes the car very enjoyable to drive. Have you ever thought about doing so?

not really. I had a larger wheel before, you can see the comparison on my first few posts: A 60 trim vs. the 50 trim wheel currently.

Since I have a stock motor I'm really limited to my power output, so I wanted to try a smaller turbo to help utilize the most power I can within my power limit. I bought this ebay turbo for ***** and giggles to see how it would perform with the intention of swapping my spare 50 trim wheel on my genuine T3 with a Super 60 wheel but found no real reason to pull it off.

Since I drive the car as a DD, for the most part, having more low-end torque is much more enjoyable than useless top-end, especially when I don't want to breach 250rwhp. So a larger turbo will have less low-end grunt and a smaller underpowered powerband.
