Finally got my supercharger coolant pump replaced after over a year. The way you'll know if yours has an issue is if are pushing it REALLY hard, as in full throttle quarter mile runs back to back, it will give you a restricted performance situation and it throws a code (P2601).

From experience, don't check the code if this happens because for some reason it clears it. Took me two times of taking it in and no code present to learn this. If it happens to you take it to the dealer and tell them what happened and what to fix. Otherwise, the car was fine so no other way to tell.

The tech said it's a separate system running off of the same tank and the way the code is tripped is if the air temp coming out is out of line for what is coming in.

When I get my TCP intake installed I'm going to get another dyno run done. I'm wondering if the pump not working is why it seemed to heat soak worse and would dump more fuel on the second run of two. The first run of my last session had the tires spin on the drum. On the second it put up the numbers in my signature. So always felt cheated. Looking for something over 500 for sure this time. I think Brutal got in my head a long time ago and even though it costs $100, I feel like I need to measure the change.

 

Hope everything is in order for Fontana in a few weeks! I am excited to see how your modified XFR compares to my essentially stock XFR!

 

Kyanite, who did your pump and how much was it?

 

Anaheim Hills did it. It was $1,268.
The pump was approx. $500.

 

Now I am! Will be a good test for sure. Will be fun to finally have some slips to post.

 

Can you help me to figure out - so XFR has two pumps? One for water (coolant) one for superchager or only one? Thanks!

 

There are two attached to the same common tank/reservoir. Or at least that's what the Jag tech that worked on it told me.

 

Got the race day off, I'm there too!

 

Perfect! We will have stock, tuned and tuned with pulley to experiment with.
