If Sam was like Pablo... Pablo won't last long at GTM, either he leaves soon or he's going to have a stroke for the amount of stress he gets from upset customers...

SS_Firehawk · 04-10-2014, 01:19 PM

Everything is put back together and running. Now the bad news... Ryan found the culprit to the low power numbers. It's only making 4lbs of boost. Now my call to GTM.

Well at least you can start the diagnostics in earnest now! Let's hope they can find the problem and fix it once and for all cause unless you, Sam and Pablo are best friends....well I'm not sure why you need spend so much time talking to them.

SS_Firehawk · 04-10-2014, 05:13 PM

I'm hoping we can fix it without having to get it back to GTM. I need two cars right now. I have zero time for the forseeable future. This only sheds light on the fact that I need a DD now.

Jordo! · 04-10-2014, 06:05 PM

Hmm. Maybe the seals in one of the compressors are blown -- did you say one was spinning freely, as in with no resistance at all?

SS_Firehawk · 04-10-2014, 06:38 PM

The Superchargers felt fine. The traction drive system could be the reason they felt different.

I know I'm machine gunning updates. I'll clean it later. Ryan is running a smoke test to check for boost leaks tomorrow

SS_Firehawk · 04-11-2014, 07:35 PM

Update. Ryan couldn't find any boost leaks. I'm going to pick it up tonight and drop it off to GTM before the end of the month. I'm not taking it back until that $hit is perfect. I'm not waiting more than several days either.

Zat_Zuma · 04-12-2014, 09:02 AM

I hope GTM can find and repair the problems

I like the premise and potential of the dual supercharger kit from GTM but your problems are tarnishing my enthusiasm for the kit

Good luck in your repairs and I hope you'll be back on the road in no time

Jordo! · 04-12-2014, 08:01 PM

Good luck!

Car made it down to PHX. Definitely nice having balls to pass cars. I even managed 18-19mpg averaging 80mph. I found another squealing pulley. Driver side SC pulley makes a lot of noise when cold. Oil temps were170-180 the whole way except a couple time when I was passing 3-4 cars at a time. No more rubber smell either. Sam really wants the car back in the shop to take care of it. Now it's on me to get it to him.

SS_Firehawk · 04-16-2014, 01:15 AM

So need an opinion. Review the video below. Does that driver side pulley making that terrible noise look a bit wobbly?

Jordo! · 04-16-2014, 01:28 AM

It looks to me like its slipping. Maybe bad tensioner or belt is a little too big/stretched.

SS_Firehawk · 04-17-2014, 12:59 PM

The belt seems really tight. The tensioner for that pulley was replaced in December. The belt should only have 2k miles on it It also goes away after the car is thoroughly warmed up (over 160)

Improving as the car warms up strikes me as something is expanding a bit to make it fit more snugly. A bad tensioner will sometimes put insufficient tension until everything warms up.

Slipping belt would also be consistent with lower boost output. If its squealing, that also suggests slipping belt.

If the pulley itself is out of round or wobbly in the center, I'd get it off of there before it wrenches itself too much...

Are they aluminum pulleys? It is certainly possible for them to warp.

Another possibility is bad bearings on the SC, which could also cause all of your symptoms.
