frazierfreud Posted November 17, 2013 Report Share Posted November 17, 2013 During first run group of the day, all was well until about halfway through. Then I started to have very jerky power under a lot of throttle. I thought maybe bad gas. I reflashed the car when I got back to the pit. I then took it for a drive on the highway and it ran smooth and strong. I went out in the second session and I noticed the car wasn't pulling as hard as usual, but thought well I'm just heat soaked. But, then I noticed the car would periodically pick up about 70 hp very abruptly during a full throttle pull. Then it lose that power at the next full throttle pull. It didn't have the power more than it did. If I was purely heat soaked, I wouldn't have abrupt shifts in power. I'm stumped. Could it be a sensor?

Frank S Posted November 17, 2013 Report Share Posted November 17, 2013 Sounds like fuel restriction of some kind? Link to comment Share on other sites More sharing options...
07SGT2899 Posted November 18, 2013 Report Share Posted November 18, 2013 Seems like issues like this are sometimes caused by failing intercooler pumps Link to comment Share on other sites More sharing options...
frazierfreud Posted November 18, 2013 Author Report Share Posted November 18, 2013 As it turns out, my PFAB intercooler reservoir cap was blew the gasket. My fluid all blew out. I couldn't fix this at the track...didn't have a replacement gasket. I would put the gasket back in place and get most of a session before the gasket blew out again. Gonna order whole new cap / gasket tomorrow. Link to comment Share on other sites More sharing options...
07SGT2899 Posted November 18, 2013 Report Share Posted November 18, 2013 glad you figured it out Link to comment Share on other sites More sharing options...
frazierfreud Posted November 18, 2013 Author Report Share Posted November 18, 2013 Actually, now I think my intercooler pump failed causing a build up of super heated fluid which caused the cap gasket to blow. The link below is my exact situation. http://www.teamshelby.com/forums/index.php/topic/74653-moroso-heat-exchanger-coolant-tank/?fromsearch=1 Link to comment Share on other sites More sharing options...
OsirisGT500 Posted November 19, 2013 Report Share Posted November 19, 2013 same thing happened to my pfab tank. It is now sitting in the garage. I switched to the roush tank. I have seen way too many of that style cap fail. I don't know for sure but the metal would conduct / keep heat longer than the plastic anyhow? You are leaning more towards track than street. Maybe sell the pfab and that will more than pay for the roush? Link to comment Share on other sites More sharing options...
OsirisGT500 Posted November 19, 2013 Report Share Posted November 19, 2013 I have a stock IC pump in the garage. FYI. Where in CA are you? Link to comment Share on other sites More sharing options...
frazierfreud Posted November 19, 2013 Author Report Share Posted November 19, 2013 I'm gonna replace the pump and hopefully that will fix the issue. I also ordered a new cap for my tank from Lethal. I've had three track weekends without issue until the pump failed (didn't see fluid flowing). I live in TX. I ordered a new pump Sunday night.
