Finished 99 GT 3S-GTE Swap from Dr. Tweak UPDATE W/PICS AND VID Page 3, Titled "The Thing That Should Not Be" Options

Rumor has it that Dynojet is well aware of this and is in the process of putting together a dyno like the Dyno DYnamics or Mustang dyno's because they're seeing a noticable swing in the market towards those two (and moreso towards the Mustand dyno).

They already have one that can be switched between normal and load holding. I think the model number is 224LC or 224LX or something like that.

Load holding is one thing, but what about setting a constant load to simulate actual road conditions (things like vehicle weight, frontal surface area, drag coefficient, ect)?? I'm not aware of a dynojet with the resistance loading (I'll call it) to make it like the car is pulling itself and not a standard drum weight, which is why the Mustang and Dyno Dynamics put out lower but more accurate numbers (when properly calibrated obviously).

alright... lets cut through the BS...

not all dynos are going to give you 100% the same numbers. one will be more, one will be less. who has the right one? no one knows!

none of that matters. what matters is that if u want to compare 2 cars side by side, then you should test them under the same conditions. same time of day, same weather, same boost level and same type of dyno. that way you can see whats going on in each one under the same conditions.

i have an awesome idea. the philly meet will be getting pushed back to somwhere around 3 weeks from now. i can book time at the dyno and we can have a meet/ dyno day!

Let me check my schedule....Yup, I'm in. That's an AWESOME idea. Will give me enough time to sort out the power steering and get the gauges working.

another one from the DR good job keep it up hope to see alot more....
can we get some pics???

[Fastbird]

First, the exhaust:













Couple of Motor Shots:









Some car shots:









Dyno Charts!!


HP vs. TQ Actually, looks like this run it made almost 260 TQ.......hmmmm.........


HP vs. Boost


HP vs. Air Fuel Ratio


Boost vs. Air Fuel Ratio

And a vid. Sorry if it sucks, but it's my first ever attempt at putting together a compliation and I had limited video to work with. Once the wheels go on this week, I'll get more.

Interior Happenings:


GReddy Boost Controller tucked away in glove box. I just need to make a hard mount for it.


SMT6 Connection Cable, Nexus Controller, and iPod cable, all in the console box, all fully functional from there.


Nexus Gauges

nice pics and vid, looks like great results... dr tweak always does awesome work

[presure2]

looks great man!
enjoy the new found power!

nice..you should give your a car a lil drop..

nice..you should give your a car a lil drop..

S-Techs are ordered and will be going on as soon as they arrive. And these are going on next week, probably Tuesday:

[jgreening]

Here are my observations and comments:

1. Exterior looks GREAT.

2. Looks like knock response at 4700 RPMs. Is timing controlled by the SMT-6?

3. A/F at 12.5 under boost is too high for my comfort level

4. Interesting that they went over the axel on the exhaust.

5. exhaust welds are not that impressive, IMO. Probably doesn't matter if it doesn't crack.

6. HKS air filter generally gets bad reviews - may want to think about replacing it.

7. The combination of knock response, the GM knock sensor, high a/f ratios, and adjusting a/f with a piggy back (which can effect timing) would worry me.

8. Why are there two couplers on the intercooler piping near the throttle body?

I wish you all the best Fastbird. Don't get boost happy!

1. Thanks!!! It's going to get better this week, and with the drop should be really nicely done.

2. Timing is not being controlled by the SMT6 yet. Have to wire a single resistor in, and Dr. Tweak couldn't source one at 2 AM.

3. A/F was starting to fluctuate badly due to heat soaking of the motor towards the end of the day. It had been steady at about 11.0 most of the day, you can see it in the video on the pull at the end.

4. Wanted the ground clearance.

5. I thought they were pretty good actually.

6. I've heard this, but it was a freebie with the motor. I'm actually looking at doing a solid 3" tube to the AFM with a better conical filter (hey, more HP to be found!!)

7. Not so sure it's knock response. It's present at that exact point EVERY time, and tended to coincide with a slight AFR dip.

8. The ATS Racing TB Inlet I guess.

Here's my concern. We know that the JDM ECU's had pretty agressive timing curves. The issue with the SMT6 is that you can't see what's already programmed, you can only make changes. If someone could post a stock JDM ST185 spark table for reference, I'd be a lot more comfortable making timing changes than in the blind. The fuel I'm comfortable changing because I can reference the AFR (or soon the pyro from in car) and see the changes. But the timing just makes me nervous without knowing where it's starting. Hopefully the A/F fluctuation from heat soak will be able to be taken care of via the SMT6 as I noticed a chart in there to actually on the fly make percentage changes based on engine temps.

That dip was actually a slight misfire, we started to get that later in the day on a few of the runs, when it started getting real hot. The ambient temperature on that last run was 97*. Sean, you should add that to the dyno sheet thread as well

wow, good numbers

well.. the HP

Congrats fastbird. You've got some pretty good numbers there, must be fun to get that kind of responce out 4 cylinders

the A/F looks a little funky but other than that things look great

It's a f****ng blast. Nuff said".

The A/F is funky for two reasons: Heat soak starting to throw things off, and the fact that the SMT6 lacks a "fine tune" capability and it's corrections ability is more big step based. With a full EMS that could easily be cleaned up to a nice flat curve.

car looks nice. i like how bone stock it looks right now. but clean up that engine a bit. paint the heatshield. it will do wonders for the engine bay. i bet those stock wheels are really easy to spin. haha

your a/f ratio is a little too lean and you did get detonation in that run. probably because its tuned too lean . there really isint much fuel to work with on a jdm ecu. it normally runs at a nice 11.5:1 ratio at 15psi and thats perfect. whoever "tuned" it, was probably just trying to lean it out and much as possible to give you some type of gain from having an sm6 in there. problem is, that when u lean the fuel out, the ecu advances timing, and this is a BIG no no. you said the a/f ratio has been good all day... do you have a wide band in the car?

oh btw,... your new redline is 7,300ish, not the 6,3000 the dyno driver was hitting.
