VIPER CYLINDER SLEEVES

[jonnyrebel2004]

I am going to need to have my cylinders re-sleeeved and I was looking on E-bay and saw these. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...&category=43977 They show that they increase your HP quite a bit and I saw wondering if anyone had every used them or knew someone that did. I have a Gorr woods port job and will have to have him touch up the sleeves. I was wondering if this would affect the performance.

 

Thanks Travis

You might talk to Eric & have him take a look at them.He would know how much work it would be to match up the sleeves & if you would gain HP.

Well I wanted to know if the sleeves were worth the extra money or if I should just buy normal sleeves. I was wondering if they really do give you that much HP gains.

I dont know how they perform,but the exuast bridge should make them hold op better.

[jonnyrebel2004]

It kinda worries me, if they are that good then why havent more people on here used them?

Buy the standard sleeve and have the ports redone to what you have now and like. No matter what sleece you use, you will still need the ports blended to your existing port job.

Yeah thats why I was wondering if the Viper sleeves were any good and when they blended would they loose their performance.

It doesn't make much sense to take someone else's idea of port shape/location etc. and try to make it work on a cylinder that's already been ported. So, you'll pay $150 or more for the sleeve, $150 installation and a port match charge for someone to go in a TRY to make everything right.

 

The best way to preserve porting isn't by using a stock sleeve and making it work; the best way is to have a custom sleeve made using each cylinder as the porting template--that way you get back EXACTLY what you started with. It isn't any more expensive (probably less) than what you are contemplating. If you like the idea of a bridged exhaust, have it put in--not a big deal.

i'd say go with a port job and new pistons as a package too.
