Namura Piston

[BlueDiablo]

I bought a Namura Piston for my blaster when it blew up and the pisont literally fell apart. Ruined my Jug, Reeds, and my crank. I guess its the metal they use or something so save your time, money and engine and buy Wiseco.

how old was this piston and was it installed correctly? before you put ti in did you check to amke sure it was was a defective piston wiht cracks or nick or anything odf that sort?

[BlueDiablo]

Its was Brand New. Installed by a mechanic. No nicks or anything. New wristpin, Needle Bearing, and circlips. Nothing was reused from the old piston. It had to have been bored correctely because i had it hot way before that. I got a refund from the company anyways. They said it had something to do with the two metals they use. So they claimed it a un-tested piston and they are still bedating wiether to pay for the damage it caused.

hmm from the sounds of it that has happened before is they can tell you why it happened. just use a wiseco but becareful to warm it up propeerly especially with a wiseco piston

[h2odill]

fuck weisco ... i will never run another wiesco ever ... ill only use pro X ... wiesco tends to blow up way to easy when you race like i do ... i ran wiesco in my banshee and i blew holes in the top of them every time i raced then i switched to prox and never blew it up again ... Pro X all the way.

Right wiseco pistons are the reason the holes formed in the top, give me a break. They are harder pistons than Pro-X and actually a forged aluminum would have a higher heat tolerance, slightly, than a cast model so that was not your problem garanteed. Pro-X are fine under 70hp, they cant handle power. Why do you think that you can only get Wiseco's for Pro-X jugs, hhhmmm cause the Pro-X piston wont stand up in the big bore jug.

[pinger.j.]

a whole burnt in top of a piston is cause it was running lean and too hot of a pug isnt it?

[fiveOnick]

Well its from being to hot from one reason or another yes that is correct. Air leak, lean, ignition problems, etc, etc.

i like wiseco pistons. so do alot of other people here that have been building drag motors for years. everybody has their own preference though???

[fiveOnick]

I am really suprised that there is no other manufacturers willing to produce specialty pistons for these motors, I mean if I had a fourstroke I would go another direction than wiseco. But when basically the only choices I have are Cast and Forged, well duh I'll take the forged piston anyday.
