RK Tek 860 ETEC out there and running great!

[RKT]

Been working on the ETEC Big Bore for a while...

Making sure it can run on pump gas and no fuel controller and be totally reliable and safe whilst making the big pull (This was of the utmost importance)!.

Pleased to announce that the 860 ETEC kit is much stronger than expected!! VERY fun sled to ride!

No fuel controller required and massive power everywhere...

This kit is very inexpensive and will surprise just about everybody once you get on the hill..

Made a few vids--> http://www.youtube.com/user/torqueline/videos?view=0 the snow was heavy and wet (can't control the weather).. More to come as the season continues.

Stay tuned!!

looks like she pulls hard. Whats the estimated Hp gain?

 

[akMcat]

How are you running a big bore without a fuel controller? Do you flash the ecu or am I missing something, does the Etec ecu self compensate or what...I'm confused

Kelsey, I noticed the tach sitting at 7900/8000. Is that the peak or is there clutching to be perfected?

Good question..
The ETECs are designed to run at 7900 and fall off hard after 8100. So, we have to keep this kit running in that range (and we have done just that)

As for HP gains?? The 925 in the videos with it is rated at 195+ HP

Nice! What is required for clutching?

Looks pretty good Kelsey, how many miles on your test motors?

No way to know for sure but doing some simple math....Probably WELL over 2,000,000 miles considering we have been doing this 860 for 6 years and almost 1000 kits out there over those 6 years..

Clutching.. Currently running stock clutching with the clickers turned down and some different gearing.. Seems to work well (better than expected)

Will be playing with other set ups as well, but this one is not bad...

When you are making this kind of power, the clutching adapts just fine...

Clutching sleds that have narrow power bands or do not make big power are difficult.. clutching sleds that have huge power band widths and make big power are easy...

Interesting coming from the guy that said never to buy a etec becuase it was impossible to a BB and it would never make any power compared to a ptec.

I may be wrong, but I think he was referring to the e-tec BB specifically.

I may be wrong, but I think he was referring to the e-tec BB specifically.

The top end of the ETEC and the PTEK are the same except for a lube hole for the RAVE valves... same bottom end as well (except for the sealed crank bearings.. not related to the big bore at all

So, you can install a PTEK engine in an ETEC (with a slight RAVE area mod) and you can install an ETEC engine in a PTEK..

So, I guess what I am getting at is this... The only difference with respect to the big bore is the fueling (injected vs carb).. ALL else remains the same.... So, the primary testing that is required , since all else is the same, is the fuel management.. and this is very easy to test. All other other critcal big bore testing components are the same between the ETEC and the PTEK.. an dhave been tested for over 6 years..

You read my mind.....

What head you running, oh and how long until SHR copies and has a kit?

A7/TJ...and once again your wrong......

I had mine running a month ago...here in MN. and at 9000'...but hey YOU know everything...just ask yourself...

Seems to me trystaad had one first, and I do recall a certain someone bashing the etec saying due to the ETEC technology a BB couldn't be done. Dave has his 872 running awsome on pump gas and no controller. My dealer cannot keep the kits in stock.

I remember hear something to that as well.

But it does look like it runs pretty good though. I guess we all will here how it holds up in the E Tec version soon enough.

As many things in this world when they come out, modification seem impossibile. As time moves on, things change and new directions appear. Technology is difficult to keep up with, especially with BRP. Give these guys credit for what they do. They give us options for performance that we would never have. It doesn't matter who was first or who is best right now, because it changes all the time and it is only an opinion that says that.
Thank you for all your hard work and R and D. It makes my life more enjoyable.

 

[HANDSOME]

Do you have any videos of an 860 vs stock e tech ?

 

[jdog1]

I would hope you have something better then that lame video!

No opinions on time frame, bone fact is Trygstad has been building the 872 for 3 yrs now with awesome success, just sayin
