Dyno the 800R

Thought I would share some info in a different thread for the 800R.
I put some of this in the 860R thread but the 800 info I thought I'd put here to keep things simple.
800R Aaen pipe Thing can & Rad valves

I needed a pipe to run on this 07 last winter as the pipe was smashed and didn't have time to mess with it. Bought the sled for the new reman motor it had anyway and was going to big bore it. Reeds were shot so installed the RAD valves. Ran good in the sled, little funky on the bottom end. Pipe pressure was spot on with the stock size outlet on the pipe ( turns out it was the same I had for the series 3 860 which is what I bought the pipe for years ago), and outlet on can sized to match. Bear in mind the Aaen pipe was for series 3 800HO which doesn't run near the port timing as the R motor but------

I was happy with the pull, nice flat graph and it showed 154hp. This was with stock 470 mains dpm hooked up. Jetting was close to perfect, just under 1200* and the plugs showed the match. Pulled the pipe & can off and put on a borrowed a stock 07' pipe & can on. Still 470 mains.
Made another pull next morning and right off noticed motor was wayyyy happier. I figured the motor might make 142 hp +- stock on my dyno from past experience because it's pretty stingy on the #'s compared to what you read & hear.
Surprise! Sucker did 156hp with an even better graph. I was amazed!! Dyno showed it was a little fat, maybe even 2 or 3 sizes.
Peaked at 8,200 but it fell off really slow to 8,300.
I've never had a motor make advertized power before. Re-checked all my data and everything was on the money.
I've heard the RAD valves will add maybe a couple, but I'm going to be curious if I find anything different when I pull it down to blueprint for the 860.
Next, changed out the harness to 05' Summit with MPEM to get away from all the electronic BS. Will make some pulls and adjust timing to get the results and then I'll have a starting point for the 860R.
Fun Fun Fun!

Do you expect to find the same results with a big bore? I know RKTEK says to use the Skinz SuperQ with his 860 while Trygstad claims more HP with stock pipe and can. I am curious what kinds of losses you would get with a different can on the Trygstad. I really don't want to use the stock can when I get my engine back from Dave. Anyone have experience with this?

Give this guy a call. Al @ 250-814-0018. He can fix you up maybe.

Great info,! also The Aaen R pipe was supposedly built around an 860

Aaen R pipe

Didn't know they made an 800R pipe. Is it stamped or welded sections?

 

[byeatts]

welded, Its really fat in mid section.. several inches larger. Very noticeable on the 07. I ran side by side with my stock pipe and huge mid gains,

Aaen 800R pipe

I don't suppose you'd have an SLP pipe for a 800R you could use to measure?
It would be cool to plug ends of pipes and fill with water / measure to compare volumes between the two pipes.
I've had really good results with the SLP pipe especially running compression with a good head. If the Aaen had more volume yet, I might have to try one.

yes we ran the SLP. The Aaen is MUCH larger. when i say larger probably 2 inches if you were to run a tape around the mid section.it sits close to the bottom of hood. SLP did not perform on our 860 or 880 as well as stock pipe.the thing to ask is if the stock pipe is tuned perfectly for the 800. how can it be spot on for a BB flowing 20% more air.this is also true about the tuned air intake. the stock box which work well on the 800 restricts on the 880. by adding 10% more cc and all the porting, Y pipes ect we enhance flows.Ive run 4 pipes and the Aaen is noticeably stronger on the 880,s.. on a 800 stock motor I cant comment. you would be a good one to Dyno and get real data.

Pipes

Thanks for the info!
Couple of questions if you don't mind---
What altitude are you running?
What size outlets are you running on pipes / can?

I could never get the SLP to run right without going bigger on the outlet. Too much pressure even on an 800R that was running compression. (stock versus 13.25-1 @ sea level)
On series 3 860 had to go up I believe 2 or 3mm &
800R was 2mm bigger I believe to get the pressure back to stock.
HUGE difference.

This is from sea level to 6K
Again, great info, thanks!!!!!!!!!!!!!!!!

Timing

After swapping to 05' harness unhooked DPM to run straight jetting.
Made some pulls with the 05' harness and MPEM with 430's. Still a little fatter than the 07' w/DPM hooked up. 410's should be right in there for a match on fueling. Will do last pulls on Mon. ( both set ups could be leaner but I'm going apples for apples just to get the baseline #'s).07' could've run 450's and 05' would run 390's I'm guessing by the data & the plugs.

The difference between 05' & 07' timing / curves shows up on the dyno.
I added 1* in the mid @ max timing, and 1* on the very top in the 05' MPEM which should be a match for timing. They're really close. If the fueling comes out the same w / 410's I'll be done with the 800R with a good baseline ready to start on the 860R with a BIG smile!!!!!!!!!

I had all those notes written down on ID of pipesg I will have to dig them up. It was larger ,Yes most of the pipes were too tight for the 880,s I build. the best combo was Aaen pipe with Aaen can on the 07, The Aaen pipe for the R motor has a large stinger as well. I ride 7 to 10K with full mod motor /and sled with 3 inch, sounds like you need to do some more Dyno work! Great info you have, thanks,

3" id outlet on pipe @ 10,000 feet?

880

Was wodering what y-pipe your using with your Aaen pipe, and also what can have you tried. I like a can that sounds good at full throttle, The BMP can I got just makes noise. Thanks Fred

Ive tried 3 Y,s The Dynoport seems best.The BMP is fatter all the way through and slowed velocity at the cylinder. dyon port is fat at pipe connection then tapers. SLP was horrible with seams and no taper, same size all the through., JMO

880

Thanks for the imfo. I am a little reluctant to change my set up but its not in my nature to leave well enough alone. Think I will try the Dyno port Y-pipe with the stock pipe and maybe later get a Aaen pipe. Can always go back to the origanal setup. Thanks Fred

 

[snowguthrie]

I have Aaen pipe and can for sale for the 800r motor. Pics in the swap meet section.

Aaen

My 880 is in a 09 XP. Unfortunetly I dont think it will fit. Thanks Fred

Finished with the 800R on the dyno. 05' harness & MPEM works nice & simple. Adjusted timing to come up with the same #'s as the 07' ECM, done! 390's with straight jetting @ sea level.
Funny thing, the 156hp out of stock everything kept bugging me. Went back over & over rechecking everything. And yes I screwed up! I installed a whole new ducting system for engine intake. When I entered weather info into the dyno computer before a pull I was going off the weather station / outside temps. I always run another sensor in the airbox for confirmation, but I forgot to look at it!!!!
Anyway, re-entered #'s and came up with 152hp solid--- Plenty safe on the jetting.
Tore down last night to get all the port timing specs this morning and now it's 860R time!!!!!!!!!!!!!!!!!!!!!!!!
I'd like to look at Aaen's 800R pipe and that Dynotport Y-pipe that Byeatts' talked about for the other 860 that I run a single on. Sounds interesting------------

I love what your doing. Cant wait for your next post. Nice work
