Waterpump findings on the Holbert car
well folks after consulting with a few folks, and letting a couple listen through the stethascope, the water pump is the culpret. Im getting REAL sick of these water pumps lasting only 1 or 2 years.!!! first one, lost an impeller, and this one has bearing noise, which only can be heard with the scope. after pulling the front of the motor apart, the pump has some movement at the pulley when i spin it, its pretty smooth, just feels loose. this small movement seems to have loosened my timing belt too (now just on the loose side of the kempf tool window.)

Hmmm. The bearings are whatever quality the manufacturer uses, so life is determined by the conditions that they 'endure'. Bearings suffer from impact damage, and from overload. Was your pump dropped sometime between the time the bearing was pressed in and the time the pump was pressed into service? No way to know really. Anybody use a hammer on the shaft during installation? That's a key to certain death. Belt too tight, enough to overload the shaft in the radial direction? Not likely, since you used the tool.
IMO, there is no such thing as 'bad luck' on this stuff. For every effect, there's a cause. So this time, make sure the UPS guy doesn't drop the pump...

He is sponsored by them. I think he sells them. I don't think the Holbert car uses them.
Mark, I assume your pump still has good seals. Have you looked into rebuilding it yourself? That way you could be sure of the bearing quality.

As FlyingDog says, he has some involvement with ERam. I've never seen him make outlandish claims, and I've seen him discuss pros and cons of them -- especially as applies to sharks -- very realistically. Here is an example, you can find more with a search.

Ive certainly had some bad luck with the pumps. If it isnt bad luck, ive had some poorly assembled pumps. the holbert car alone, had its original pump removed. (probably the first mistake) the new replacement one leaked, and that cost me another day of labor at CT. sure, guaranteed by SSF, but who pays for the labor!!????? second pump tensioned perfectly, checked often, made noises when cold for an entire season, second season started to have overheating issues. thought it was a flakey thermostat, (which i did have) and it turned out that the plastic impeller was slipping on the shaft. (very poor design) finally in qualifying, it went and after awhile we figured out the pump was not circulating water. Now, that replacement pump was making a faint noise, bearing noise. probably ok, but im sure as it wears , it would have caused a problem (slipped belt, etc)
new pump on order, 4th time a charm????

Thanks Dave.
I still own the patent of the axial flow electric supercharger and the company is growing slowly, but im not actively involved in the day to day business activities. Its a tough sell, especially to the market that it focuses on . The Holbert car doesnt use them, as it doesnt provide enough gain to make it worth the effort. The limit of the HP gains on the eRAM is related to max HP produced by the engine. 300flywheel hp seems to be the limit.
On my 240hp rear wheel part euro 4.7, it was as effective as many of the mods i had done, at close to the same price. 10hp for $300 is pretty par for the course, if you are a realist.

try the stethascope technique. not many folks do this, but its very telling. that bolt hole that usually holds the driven fan on the pre-87s, allows you to hear exactly what the bearing is doing. it should only be a swishing sound, not a 4 cylinder reving engine sound! (kind of a rattle at idle, but pretty bad at higher rpms. no audible clue without the stethascope)
