Default My 1.6 Turbo Dyno Results

I have been working most of the spring and summer on my turbo build seen here: Oochi's turbo 1.6 build - ClubRoadster.net and I recently took it a buddy of mine to straighten out the high and medium loads on the map. I trusted him much more than myself. And here are my results on a mustang dyno.

Quick rundown:
Stock 90 1.6 with 166k miles
Megasquirt 3X built myself
Tacotaco cast iron manifold
Ebay Godspeed T3 48trim turbo
RX7 460cc injectors
Walbro 190 fuel pump
1.8 driveshaft, axles, welded diff
Conquest intercooler with custom endtanks
Custom 2.5'' over-the-radiator intercooler piping
Custom 2.5'' to 3'' vband downpipe (open)
Variable TPS
NGK BRK7E-6097 Spark plugs
Mazdaspeed comp motor mounts
Urethane diff mounts






The result on his very first base conservative map made 208whp @5800something rpm. I was having boost creep issues after that and was hitting boost cut. Has anyone with this turbo had wastegate issues like this?

I was surprised with this power and trying to make it any higher makes me worry about the tranny.

The idle still sucks *****. I closed off my IACV. So if someone would be as so kind of helping with that I would be delighted to send you the .msq

200+whp is pretty good on a mustang dyno. I'm sure it's fun as hell.

If I read the mod list right, he's not even running an exhaust. Open 3" downpipe.

Based upon that, power is not surprising. Good numbers. Mustangs are usually pretty consistent and conservative.

+1 on this must be fun!

Oh god yes. It's just annoyingly loud and makes me smell bad

So are my options just going with an external gate or could I grind some junk out behind the flap so it opens up a bit more?

You are correct. I wish I had full exhaust though. It is fun for sure haha

Full exhaust might help your creep. Porting the IWG port will definitely help.

Got pics of your timing map and AFR logs? I'm curious to see how DK did.

I can grab them sometime. We installed the most current to my megasquirt using his laptop so I'm going to have to redo the firmware with mine to pull junk off of it. My gas mileage is that of a tractor though

porting the hole is trivial.

If you don't saying where and how much was the tuning? I'm in your area and will need similar services shortly.

Louisville, DK Goodrich tuning. There's actually a bunch of good tuners there.

Sorry to answer for OP, I've just talked with most of them in the area.

If it was properly tuned you should be getting ~30mpg and have a good idle. Get your money back if not.
