Anyone Port their own engines?

[EnzoFerrari]

I'm always looking to improve performance of any engine i have.
I opened up my novarossi and began porting the sleeve. I raised the exhaust port about 1mm. I also lighten my crank.

I'll post some pics later tonite.

Anyone here do their own porting or is this a very secretive thing.

There is some info in this thread.

Also if you do a search you might find some info. I know there are a few tutorials on doing this on the web.

I do all my super mods on my engines and for others as well.
I have my own business on the side from natural work.
I do racing setups for people and run them to make sude it performs to the max and I do super modds to engines for their full out race cars.

I drank some port last night, does that count?


Seriously, if you are looking for info, use the search feature here. Also do a google search, I have seen some sites with some good tutorials in them.

a guy around here does them as a side business. www.ebmods.com is his site.

he works on everything. the other day i was in there and he was doing a heli engine from washington state.

if anyone wants a quality job done by someone that knows what he's doing, check him out.

i'd never do it myself.

Just like "port polishing" and moddding a motor you obviously have to know what the phuck your doing. If I had some money to burn I'd definitley be willing to give one of ebmods .26 Pico/wasp motors a run and c if I felt that almost double the cost of the "stock" motor was worth the performance gain or lack their of.


Enzo - Porting definitel isn't a "secritive" thing IMHO for RC motors but most people could give a chit or don't think the sometimes subtle increase in performance outways the sometimes serious decrease in general motor life.

IMHO the best anology for "porting" etc in most cases is like overclocking a computer video card on a fulltime basis (no just for temp benchmarks). Yes, you'll c an improvement in perfromance and sometimes a substantial imporvement, but is it worth the usually substantial decrease in product life.

I certainly agree with your statement as it pertains to overclocking. I have built a few overclock beasts in my day LOL..

I don't know if i was lucky or not but I have 3 gallons or more through my ported TRX .15 and a gallon of that was 30% nitro. This engine still cranks. There is no signs of the engine quiting yet. I think if the port job is done correct you will get a decent product life out of your engine. I think the problem usually is if the con rod is shaved too much it eventually blows. I know some guys that port engines for money will not shave the con rod to make sure there is not a weak point there.

I still think it all goes back to. If the engine was built from the ground up to be a performance engine, porting it will probably not show a substantial amount of gain in power.

The TRX .15 was not built as a race engine, so there was plenty of room for porting to help.

I paid 75 bucks shipped for my TRX .15 new off of flea bay, i had no problem throwing another 35 buck to have it ported. The engine performs like a beast.

I certainly would not get a $250+ race engine ported...Just not worth the risk of destruction.
