      Here is video taken during that hot day last week. Our EGT monitoring showed max temperatures well under the manufacturer's 1050˚c temperature limit.

    2. Just how strong are the stock connecting rods?

      Can anyone tell me if there's a substantial difference between the connecting rods in the 2.5L and those in the turbocharged 1.8T? They sure look to be the same basic design:

      1.8T...

      First quick-and-dirty exploration will be an adapter plate that'll go between the flanges. Sort of like a restrictor plate, it'll knock down the T3 opening at the manifold to T25. This will speed...

      I sorted out a confusing problem with the car yesterday. The turbo wasn't boosting with much enthusiasm while on the dyno over the weekend. We were pushing it with 90% boost duty cycles in the...

      I agree. Its a frustration to be told of your engine's potential doom owing to "low end torque spike". It's a red herring. Or at least an oversimplification. Anyway, I operate with this strategy:...

      Let's look at this from another angle: A given torque value being applied 5000 times per minute is considerably more wearing than that same value applied at 3000 times. Yes, the "dwell time" at...

      Lacking upgrades to the other hardware -- fueling in particular, but also intercooling and exhuast -- there's no potential at all.

      Torque is torque. A given value is the same amount of force on the components no matter the engine speed. But detonation at that torque level is a real concern. This leads me to a topic I wanted...

      We're giving BPY-engine pistons a try. That FSI engine runs 10.5:1 compression. Should make for a responsive low end. Plus they're cheap.

      We like it plenty. It's our recommendation for all Mk4 cars running the F21T. This is much better solution than an in-line pump ganged to an old, in-tank unit.

      Actually, past 5000rpms the engine started to struggle. We're working with C2 to figure out why that is. But I'm pleased to have the power onset where it should be... 300whtq by 3000rpms is a good...

      Boost wasn't holding at the 16psi that it could do on the street. Nevertheless good power for 14psi, ramped upward from 10 at onset:

      37˚C - 39˚C on every pull. Basically ambient. I've seen logs from other cars running in ambient temperatures 30˚C cooler that nevertheless see these IATs. I don't think it mattered how hot it was....

      Appleton is in a lovely part of the country. Great back-roads (weather permitting, of course).

      Solid results on a hot, muggy day at FFE's dyno. This is a Eurodyne Maestro-tuned GTI running STOCK INJECTORS. The car has an excellent intercooling system -- A Golf R unit in the stock location...

      Well, these logs are a major win. Not that they offer anything surprising, but they confirm what everybody already knew: stock, these motors don't flow much:

      Yup. Just log block 002 in 3rd gear from 1500-6500rpms. No shifts, no throttle lifts.

      One of them will be going into an AMU-engine TT225 at ForceFed Engineering, where next week it'll be paired with our F23 on Maestro. Car is more or less stock, so it'll be an interesting test to see...

      I'd settle for simply seeing some N/A data logs. The only ones I have are those I graphed here. Who can share?

      OP

      Did you compare the pictures posted here to the turbo you have? Because anything's possible with an Ebay-sourced turbo, including the wrong part number. But the visual differences between...
