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?

I know RB mods done it before and its really awesome..

Here is some info on how to modify NX76 engine by Team CEN driver in Franc

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?[:@]

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,
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[>:]

Nitro, that would do it!! glad you figured it out......
