Yes. He's still on the stock turbo.

Yup, that's the plan. He didn't get retuned for that dyno run because we still have an intake manifold and throttle body to put on. We also just wanted to see what the raw gains were. I'm sure once everything is swapped and tuned properly, we'll see some nice gains throughout the power band.

Why would the A/F have changed at all though with such a minor exhaust side change. Was it a lot different?

Why the change? I don't know, but my car got quite a bit richer after the o2 elim dp install so for whatever reason higher flowing exhaust path = rich on my car.

November tune vs. ported manifold run (for some reason the dyno database won't show my AFR from the pre-manifold baseline, but at the time we compared it vs. the November tune and it was nearly identical):

Ported IM/TB install tonight and retune tomorrow!

Armando is coming over after work and we're going to stay at it until the job is done

Ported stock manifolds did nothing but help spool on the 8/9. My guess is the higher flowing exhaust is playing differently on the X since it has exhaust MIVEC (which only the X has), with minor changes to that I expect to get my spool back.

I fully agree. Already just in the back-to-back untuned comparison you can see gains of +9whp in some areas above 5,500 RPM which is a really good sign.

Might stop by to Chk it out

Insanely impressive for a stock head! Already very smooth and wide open, barely even a need for any porting, if anything I'd say it only "needs" a tiny bit of smoothing/cleanup.

We got the Mil.Spec IM/TB set along with MAP phenolic gasket installed tonight. Took us about 5 hours start to finish which included a pizza/Throwback Dew break and time to R&R the stock undertray. The manifold itself wasn't really a problem nor were the support brackets...it was all the damn wiring harness clips and the TB coolant line clamps which were at a very precarious angle. The coolant lines to the TB could easily be bypassed with a 180* bent hose to loop to/from the thermostat housing. We decided to skip this for now since we didn't have a hose like that, didn't want to kink a factory line, and were excited to just get the car back together! I had no idea just how much material Aby @ Mil.Spec actually removed from the IM runners until I had it side-by-side with the stocker! I reset the ECU and overall the car seems to be idling just fine; a tad high right after startup but the ECU quickly corrects and brings it down (this may just be because I reset the ECU, I'll find out tomorrow once I actually drive it a bit).

My tune is scheduled for noon tomorrow so later on in the afternoon I'll be reporting back with some final numbers

I have a new found HATE for that stupid little vac line clamps. Damn them all to hell!

Aside from that, can't wait to see the results of all our labor over the past few weeks! I'm excited to see the final results!

**scheides** · 03-19-2011

Nice! Good luck tomorrow, can't wait to see the results!

I lost a fair bit of blood on the fuel return line ones. I bought a couple pairs of needle nose at different angles and life is more pleasant now.

**Kracka** · 03-19-2011

After the car got a chance to learn the new TB it idles just as smooth and perfectly as stock! So far I'm very impressed with these Mil.Spec products.

Do they make stuff for DSMs?

Not as far as I know, I think Evos only.

turbotalon1g · 03-19-2011

I tried to look for a site but didn't find anything.
Results?

**Kracka** · 03-19-2011

I don't believe they have a website. Aby @ Mil.Spec, the guy who does the porting, is an airflow engineer who's done work for professional race teams (NASCAR, CART, IRL, etc.).

Sadly though, no results for today

A Mazdaspeed3 came in from Louisianna for a 10am appointment and it was all sorts of booty. As of 3pm they're still working on it and trying to get it to run right. Gatorade bottle caps used to plug stuff, none of the clamps were tightened down, something wrong with the wastegate, etc. Since Andrew and Emily will be here soon I decided to just head home and reschedule for Tuesday afternoon.

Suckfest, sorry to hear man.

Say hi to ass for me. Have a fun weekend I'm sure its hella nice out there.

Aby sounds like the perfect person to be making this stuff then.

Yes perfect weather low 80's with a nice breeze..btw check out the new kingsford charcoal radio ad.

Rmondoh · 03-23-2011

You guys will be in for a treat once Kracka posts results. There's an unexpected twist though!

Dun dun dun!!!

Speed hole in the block?
