Default Anyone ported and flowed an NX76 engine?

I read a while back an article PPman posted about internal modifications that can be done to the NX76, (and any other Nitro engine I guess), to improve air flow inside the engine and so increase efficency and performance?

Well, after my original engine snapped its con rod last week [&o], I though it was time for a new one to get all the new mods Cen has been doing to the NX76, (Redesigned crank, carb etc). So I purchased a new GST sourced Block, (with crank & bearings), a piston and sleave and also what I believe to be a new carb with the redesigned needles that are easier to tune and set up, (Or so Cen say ).

But before I put it all together, I was wondering whether to take my Dremel to it [X(] and improve its breathing.

So, does anyone have experience of porting and flowing an NX76/Nitro engine?

Any results/conclusions you'd care to share?

Hi Guys,
Is it just me, or everyone?

When I go to the above link I can't access the other photo's, i.e. the numbered links below the posted subject photo.
eg. NX76 Modification - I can't operate the 1, 2, 3, 4 photo links. (Obvious to me, that they are meant to be more detailed photo's)

What say you CEN Racing?[:@]

Is it just me, .46NitroAddict [>:]

Hey nitro, Those are "hover" Links you have to hover your cursor over them for a couple seconds to allow the download of the pictures. They will change in a couple seconds. once you have seen the picture it will change very quickly until you clean ou you temp. internet files. Its a computer thing!! Do you trust me???lol

I am glad the conversation has turned to 'how to use Cen's site tutorial'!

So,.... has anyone tried it??

Well, I have spent most of today following PPman's pictures, building the engine and running it in using the 'heat cycle' method found here:http://www.johnnycoolguy.com/JCGR/ma..._break-in.html

Well it seems to have work a treat, the engine fires on the FIRST pull, something the old engine NEVER did!!!
I have only run it in with no wheels on the bench, so I have yet to see if there are many improvement, but with the work I have done I'd be very surprised if there is no noticeable improvement.

Oh and I too had problems with the pictures [sm=red_smile.gif][sm=red_smile.gif][sm=rolleyes.gif]

So I PM'd PPman who sent me the full article.
I used the net to translate it into English, but its a bit gibberish [], but you can work out what it is getting at.

If anyone would like me to mail it to them, then PM me with your email address.

All I can say is go one, strip your engine down and get grinding!!!!

Hey The Real Dogman,
ORIGINAL: The Real Dogman

Hey nitro, ....... Do you trust me???lol
Implicitly! Still didn't work for me until, I turned ON the 'show pictures' in 'tools' - 'Internet options' - 'Advanced' - 'multimedia'. [:@][:@][:@] I have a small download limit, & normally browse with it off, only showing pictures when I need! (Back fired big time on me this time - I guess I was expecting something simmilar to how the larger picture links work here!)

Scott_GTR,
Once you get the beast going again & fully run in please update us!

Regards, .46NitroAddict[>:]
