My 1992 GTI

[DocWalt]

Installed the chip today. Twenty minute job, even in this heat. It feels like it wants to keep going above 6500 now, way more than I was used to. At about 7300 it's really petering out. I haven't felt the need to go beyond that, but my rev limiter is now at 7600. Seems like everywhere in the rev range it's a bit more powerful.

Supposedly it takes 3 cold starts before it learns the car. I'll report back with any changes

Welp, fuel pump died during my last run at autocross. Had to abandon my car in the parking lot and go home to pick up a spare pump to swap out.

I ended up being 2nd fastest novice and my brother was 3rd fastest novice. Sweet!

I picked up a GoPro so here are some videos. you can pretty much skip the first 1:30 of each, I was too lazy to edit.

- First run, pretty mediocre

- Second run, interrupted by a spinning BMW

- Third run, my fastest time.

- Fourth run & Re-run to make up for the aborted second run. The main fuel pump dies in this video, my car just lost all power.

Supposedly I was hiking up the inside rear wheel in nearly every turn. Waiting for pics as evidence.

Replacing the fuel pump:


Resetting the ECU because I stupidly didn't bring a jumper to prime the pump and the ECU over-adjusted too rich:

Be carefull at high revs if you're on stock rod bolts, aparently they stretch!.

[DocWalt]

Hmm. Not heard of that issue before without some serious power. I'm still on stock rod bolts, and I don't really want to go through the hassle of switching to ARPs, but it might be a good idea especially because of the abuse my engine has already taken.

[DocWalt]

Getting interesting... Needs some machine work on the rod journals, but that's not a big deal. Just need to order oversized rod bearings for my "spare" engine build.

My car's been running perfectly. Just not fast enough. New engine will be P&P with some other tricks if everything works out. Will be stock pistons (10.8:1) and rods on the above crank.

So, what do you have up your sleeves?

[DocWalt]

We'll see. I still have to decide if I want to have that crank worked on. It's not a huge performance benefit, but every little bit would be nice.

So how does this car compare to the VR4 and Evo? I can't imagine it is more fun all around but I'm sure its cheaper!

[DocWalt]

It is a hell of a lot of fun actually. Significantly slower in a straight line, but since I'm not worried about hurting it I'm much more willing to abuse it. It's not really much cheaper than the VR4 at the current rate... At the moment it doesn't need anything except for an oil change and more power
