Full Version: etec mods
i have an 09 gade etec and was wondering what kind of mods are good for more power through the rpm ranges. like pipes, intakes that sort of thing. not engine work like pistions and heads as i am not currenty set up for that kind of work. also if clutching is a good option. any thoughts would be helpful but i know there is no replacement for displacement. or nitrous and a turbo its getting a 1.75 inch track and geared in a few months as well

Bondi airbox and a Dunn Clutch kit and your golden.
Airbox is bolt on 3+ h p and looses that stumble when you stab the gas back off and stab it again.

I just visited the Bondi website and they only list an airbox for the 800 engine. Where did you get the one for the 600 etec?

Same box for both engines, call them up if you want some info on the 600 testing.

Thanks for the info. I've read a lot of good things about the airbox. Dunn doesn't list a clutch kit for the etec, just for the 500/600ho. Do you know if this is the same kit for the etec 600ho?
Thanks for the help.
try cudney racing for your etec clucth he is a proven etec nut.

go to laflamme racing they got an awsome clutch
Just finished installing the Bondi and the VForce3's. No ride time but ran it on the track stand for a solid 10 minutes - no warning lights or anything. Not much to go on but my stock TNT E-Tech and my Custom with the Bondi & VForce - BIG difference just on the track stand. Response on the custom is crazy!

how difficult was it to get the vforce3s on the machine and is there is a full pipe kit for the etec yet

Not too hard. It looks a lot more difficult than it is. Once you take the airbox off you can see it's very easy. There are 3 or 4 pipe can combos, everyone has lost hp not gained. Don't waste the money. I have talked to numerous people and a few ran the dyno. All felt the loss when riding. You can run a can if you want some lose hp. MBRP is the best for not losing (nobody has actual gains).

more about trimming the fat get rid of heavy oem parts and a better sound. nothing like a 2 stroke at 7000 plus rpm

No point in trimming fat if you loose HP in the process.

iv been looking at some online and they all say that they produce up to 10hp more than stock exaughst so how can it actually be a loss in hp the only thing i can think of is that there too big and dont have enough back pressure thats with the full pipe kit.

The answer is simple, theyre feeding you a line of crap to sell you a muffler.
Put vforce3 reeds and aaen pipe and can on my 09 etec. Reeds did a good job but wit the pipe and can I was olny hitting 7400 rpm with them. put the stock setup back on right away and was hitting 8100 8200 again. DONT GET AAEN.
I also question the improvement of the Bondi airbox on a 600HO Etec for two reasons. First, the 600 is 25% smaller pulling thru the same 800R airbox... does it need additional airflow? Or can it use it?
Second, if you really did add additional airflow (which I doubt) how do you richen the fuel air mixture to use the added air. The Etec from the Dyno Tests nunbers I have observed at dynotec indicate very lean fuel air mixtures (I am sure they get away running this way by the injectors spraying cooling fuel on the piston top). But so far as I know, no one has cracked the box - Ie there is no boondocker box for adjusting fuel air yet for the Etec.
The V Force 3 reeds I can understand because the Etec engine useds he old style doo reeds, not the v force copies like on the 800. One might get a slight improvement in throttle response there.
Seemed like about 50% of the guys who put pipes on their SDI's without adding a boondocker or it's equivalent wound up losing pistons... that number might be high because you only hear mostly from the guys that blew up. You might get away with a single pipe on the Etec again because of spraying fuel directly on the piston, but I wonder for how long. Fortunately most of the pipes don't make power and stress the engine so it is probably not an issue.
Clutching is obviously the first thing to do with the Etec... it has that miserable 48 degree straight helix and engagement is pretty low at 3400 rpm. But I will say one thing, I think from a stock stand point, I have never had a doo primary where the belt has risen so high on the pulleys... opps, I don't have a stock secondary helix anymore. Howerd's if you are in the US and Cudney if you are in Canada, since Joey has not been working on a 600Etec yet is probably the way to go.
I would like to find a quiet aftermarket silencer if only to get at the chain case without pulling the silencer, I hate that lower spring to the pipe. Weight loss would not be bad either.
SkidooorNothing do you really think that MBRP can is reasonalbly quiet? Any MBRP can - even there quiet ones that I have used in the past, has been pretty noisey. I would buy in an instant if we had a quiet one! True decibel readings from the various manufactures would sure be nice. Probably impossible to equal stock sounds with lesser volumes without being too restrictive.

i have a mbrp can on my etec as well and can justify for how quiet it is. I can barely tell the difference over stock.

MBRP silencer on the E-Tec is so quiet it's barely above stock. Plus, trust me I have done an over abundance of homework to understand this motor and everything I have done to only gain or at least not lose, the MBRP is one of the only cans to not lose for real. I love it!
The Bondi doesn't scare me because the E-Tec is set up for elevation changes, you can't rejet it right? Well when the elevation changes the motor has to adjust the air / fuel mix so putting the Bondi on is just allowing more air through but the computer will compensate. The guys at Bondi ran an E-Tec hard all last season trying to get her to blow and never had a single issue. They knew the box would work with the motor but that is why they didn't endourse it until this year - that is straight from the owners mouth.
That is good news guys on the quietness of the MBRP Etec Silencer! Thanks! And you can access the chain case and the chain adjuster without removing the silencer?
Yes the Etec adjusts for altitude but that is based on barometric pressure. Not on adding oxygen at the same barometric pressure... so no, it doesn't compensate for the airbox change. It won't add anymore fuel if the barometric sensor pressure doesn't change and it won't change for the airbox change. Airbox change if it does anything, it would increase the air/oxygen going into the engine and make it leaner when it is at the same pressure. The fact that it has not hurt an a 600Etec, implies to me that it is not doing anything for the 600 engine, that the airbox sized for the 800 is plenty sufficient for the 600Etec as it is.
That or piston cooling from the fuel sprayed on the pistons protects it.
An air or oxygen quantity change that doesn't impact barometric pressure, should scare you, the Etec can't adjust for it! It would need a mass airflow sensor to compensate for that.

That's why I love Dootalk, good info all the time!
Makes sense what you're saying, so I am just going to have to go with the tenth wonder of the world theory here. I know the guys at Bondi tested it for a full season and pushed it to see if they could get any issues and came up with none. Obviously they are now endoursing it. I also know a fellow Dootalker that ran all last season and dynoed it for a 3hp gain - just the box. He also had no issues.
I figure I can run my sled long enough to blow it up and swap in an 800 E-Tec!
