Bump, reasonable offer will be accepted. Hate to have this hanging on the wall.

I just had an autocross event yesterday and I get what you mean. It's almost as if the vacuum booster is a regulator itself and as you push on the pedal, it increases vacuum. When you have a lower input pressure, you have normal assist until you hit that level, then the assist doesn't increase...

I know this isn't exactly a Cobalt part, but there's lots of Ecotec members here who may be able to help. I'm looking for an F23 with the 4.17 final drive. This is out of early HHRs. Within a 4-5 hour drive of 53913 preferable. Thanks!

This was my problem. In my case, it was the crank position sensor wiring. I ran new wires to the sensor from the ECM and my problem was solved.

After a few days of driving, I can confirm it sounds amazing. Completely eliminated rhaspiness and has a real muted tone. Cold start is mellow and idle is nearly silent. Still gets rowdy when on it, though! Will post components and cost in my build thread.

For sale is a 3" exhaust as build by DF. I got this a couple years ago, but found it to be too loud for my liking. Has a high temp silver spray paint on it. Baked appropriately when applied. I noticed a decent power gain on my 2.2 supercharged when I went from my 2" to this one. Warning: it...

Not to bump an old thread, but here's the direction I took for quietness and better support to reduce hanging weight. More info can be found on last page of my build log. Super happy with it so far but have yet to drive it. The rhaspiness is gone and I love that it's supported by the frame...

I completed a big step almost a year in the making today. My biggest gripe with the Goblin always was the exhaust. It's loud, it sounds like a tractor, and it's not exactly eye candy. Two years ago I found a single in dual out Vibrant muffler that seemed like it could be a good fit. I bought...

The crank signals may be different between an LE5 and an L61. Will have to figure out which computer to run it with. Also will probably have to drill a hole in the head for the PCV for the LSJ supercharger manifold.

Does anyone know if DF has released the drawing so a new windshield can be cut via CNC router or similar? I'm not super confident in my jig saw skills.

Found a set! Thanks! I'd like to pick up a fender set and wondering if anybody has some and isn't planning to install. At this point, any of the three width options would work for me. Can pick up within a couple hundred miles of 53913 otherwise would like shipped. PM me price. Thanks!

RITDR, I know it's been a hot minute since this post, but If you're still around, want to give you the dimensions you asked for. This has been a great gage pod for the last couple years. I added the hood pop so it would fit. If there was any way to shave 3/16" off the overall height, it would...

I would ask to see Dyno results before that investment. While it will definitely increase throttle response, probably to an annoying point on a Goblin, it's hard to believe a 10% bump.

Couple thoughts to add to this. I consider Pennzoil synchromesh a good fluid and have used on several transmissions over time. It helped wake up my notchy F23. If you go above factory fill level, you may get leakage out the vent during hard cornering. I lost fluid at a couple autocrosses until...

The bug guts are kind of like a polishing compound. :p
