I am aware of the killer chiller that many Ford guys run with their KB Blowers. The principle is sound that is to cool the IC fluid as much as possible to lower the IAT under high boost levels. Since I only use my car in the summer, and I am thrifty (cheap) I am pondering this thrifty (cheap) solution. Connect the IC line that returns from the blower to my heater core input line on the firewall. Run the return line from the heater core on the firewall to my reserve tank that holds my IC cooling fluid. Run my a/c that will cool the water in the heater core and thus lower the temp of my IC fluid. I would just loop off my heater line at the motor. Anybody done this???

Thrifty and KB dont got in the same sentence. There are solutions to keeping the IAT's LOWER, but none of them are cheap. My friend and I have been fighting this for a couple years now.

 

You know this is really a theoretical problem in my mind. I really dont race my car. It is very reliable. The only problem with the heat soak and IAT's is in the summer when temps are 95 or hotter. Is that IAT reading really true with the heat soak factor? Even with the new improved sensor I really dont believe it. My oil temp tends to sneak up to the 240's in the summer but an oil cooler is the project for the winter and that should fix that. I use meth that lets me run a more aggressive tune and does seem to allow the temps to return to baseline very quickly after boost. Overall it's a blast to drive and very quick from the light. Would I do the KB again knowing what I know now ? That is the problem. NO ! I would get a system that was tried and true. I feel most of my problems are all the same KB problems on all C5's KB's. The air inlet restriction problem. Where is that new manifold ? The IAT"s. Belts that jump unless you go the 8 rib set up. The 300 dollar tensioners still do not fix that. The friction drive set up that uses a tool to hold the KB pulley while you torque the bolt. What crap. You have to modify the tool from KB or you strip the hex bolt every time. If any oil is on the mating surface of the pulley then the pulley spins and no boost is made. Jeff has done wonders to help with these problems but the fact remains. This KB C5 kit was sold without research. We were the test monkeys. The test monkeys said the heat soak was a problem. Guess what they now make a C5 kit that has cooling going into the head unit. If I really was into performace and 1/4 times I would be upset but as I said I am happy with the KB for my application and a far a SCs go thats all that matters

Im sorry to hear you have had so may issues. We on the other hand have had only the IAT issue and it was cured by the use of a water/methanol mix.

The friction drive pulley setup has not given us any issues nor did the pulley tool that was supplied by KB, never came close to stripping out a pulley bolt. We never ran a 6 rib setup on the car, 8 from the get go and the only belt jumping issue we had was related to a crappy alternator pulley. We did however SNAP the stock tensioner off and upgrade to the HD unit he sells and have had no issues with the drive since then. I found if you use the adjusting holes for the idler pulleys to really wrap the belt tight against the blower drive that it eliminates pretty much all belt slip issues as well as tracking problems.

Car doesnt see any dragstrip time but it sees alot of road coarse track time and has never givin us a problem.

BUT, the kit is for sale currently. Onto bigger and better things.

 

I just gave my friend who is working on my car money to get the "Liquid Cooled" option for the 2.8 done to my blower. It will probably be sent in to KB around February. Either way I will post up results to let everyone know if its worth it or not. Got my fingers crossed can't afford it not to be worth anything.

 

 

As usual nothing constructive on this topic.....

 

Water/Methanol is a sure fire way to lower your IAT with a positive displacement blower. I've seen it on Vipers several times.

 

Well there are other options.

 

I would think the heater core would be blocked when the A/C is on or the hot/cold **** is turned?

So would you have to have the **** turned to "hot" and the A/C on to get the effect you are looking for?

Will have to look at the manual for a little insight?

 

Heater core has nothing to do with this blower. The intercooler is completely seperate from your cars cooling system.

Unless you meant somthing else in wich case im officially lost.... The cars cooling system as zero to do with the KB setup.

 

Ill give ya that one.......
