It's pretty much inherent in the design of the engine. A pretty extreme example of turbo lag. Your motor doesn't make any HP until the turbo spins up, but the turbo takes a while to spin up because it's driven by exhaust gasses which are being limited by the low RPM's. It's a sick circle of suck. (pun intended)

Not saying there's a huge amount of lag in a K03, because there isn't. At the right RPM in the right gear, there's almost no lag on a K03. But you see where I'm going with this whole rant.

 

So basically....our cars are slow haha

 

Yep! But you're well on your way to fixing it. Light weight flywheel, free flowing exhaust, etc.

 

Hopefully it will be all fixed and ill actually be able to compete with my buds mustang (eventually...)

 

You're already winning

 

I remember getting that bucking with the stock K03! I always thought it was due to the K03 "running out of breath" or timing pull due to heat soak, or something like that.

In any case, the only bucking I get is ~1800-2200 RPM, worse when the engine is cold, and I have a few theories as to what's causing it (AFR gauge shows the engine goes lean in this range, under certain loads). But I think this bucking may just be affecting my engine, and is not necessarily related to FrankenTurbo or United Motorsport, or the combination of the two.

Like I mentioned above, my car has a weird issue with bucking, and I think my car's excessive emissions may be related to it. Even with the 034 Motorsport HFC I still get plenty of black soot on my exhaust tips, my exhaust smells pretty strongly with the windows down, and I definitely didn't pass the smog test.

Also, for our visual test we can't have ANYTHING related to emissions/intake modified without a CARB exemption sticker for the particular part. So even having a fuel pressure gauge installed (on a bone-stock engine) I would fail.

 

God I can't wait to get a frankenturbo, I can't even imagine how much more in love I will be with my car after I drop one in

And as far as the already winning to a mustang, that statement is so true. He had an 01 a4 1.8t that had the weird sunroof problem so he sold it instead of getting a little bit of guys and fixing it himself (sold it because of only the sunroof)....traitors

 

Is the united motorsports stage 3 for the aeb the best for the ft? I would assume it is, so it looks like new injectors is also on the master plan. Do aeb have a 70mm maf housing or should I pick one of those up too

Or I could go to my somewhat local ngp racing shop and have a custom dyno tune if that would work better

I'm gunna order a fmic and 630ccs (if that's what I need) this week, and get a test pipe put on. Then when I get the money, chip and ft

 

Are you closer to NGP Aberdeen or NGP Lorton?

 

I'm about 50 minutes from lorton and hour and 15 from aberdeen
