Engine build

[mike lowary]

NRHS 1050 kit, stage 2 heads, cat 3 cams, xb12 throttle body, xb12 header, open airbox, carbon jardine, dual widebands tuned by me. Doing the break in now. Should be pretty rowdy

 

[Cooter]

Awesome! Any chance of posting the dyno charts you did for tuning?

 

[mike lowary]

Haven't been to the dyno yet on this motor as im still breaking it in. Once i get to that point ill post up the info.

 

[mike lowary]

Definitely not cool enough to run true duals on the lightning. God my neighbors would burn my house down. I'm a firm believer in everything matching. I've done suspension and brake upgrades to go with the extra power. Cause why wouldn't you?

 

[cossack84]

Mike bike looks great.
How do you data log the two wide bands?

 

[mike lowary]

Thanks cossack. I just do one cylinder at a time. So I’ll go out on a tune run with the front cylinder o2 plugged in. Then get back to the house upload the tune for front. Unplug front, plug in rear. You get the idea

 

[mike lowary]

I use ecmspy and megalog viewer to tune with.

So I don't know much about tuning, but was curious about the dual wideband O2 sensors vs. a baro sensor. I've been thinking of eventually getting the baro sensor for rides at higher altitude.

 

[mike lowary]

I only run open loop. I don’t know much about the baro sensors. I rarely stray too far from the house, so altitude isn’t in my worry list. I’m probably wrong but it seems like it would take a significant change in altitude to see a big difference in the way the bike runs. Idk

How does it ride, is it "streetable" ? Would or could you say it is comparable to a 12 with the money spent or do you prefer the stroke or engine of a 984 built? Meaning you probably could have sold the 9 and got a 12 with the extra mod money, I think. Just curious, I feel after everything I've read it's kinda split down the middle with was the juice worth the squeeze with dollars to gains. I think it's awesome though and hope it works out. Kudos!:up:

I had almost this exact setup before. That setup was 1050 kit, stage 1 heads, xb12 throttle body, xb12 header, carbon jardine, open air box, dual wide bands. I do not have the dyno chart. It did dyno at 93hp 82tq to the tire. I know without proof it’s hearsay. However that being said, this setup adds stage 2 heads and cat 3 cams. I would expect to see 100hp to the tire if not more. Doubt I’d get out of the 80s on torque. Never know. It’s very streetable. The cams are very mild. Runs like stock. Till you twist the throttle. Also added the 04 up belt upgrade with a Baker aluminum trans pulley and a lightened front sprocket. This complete setup feels significantly faster than the previous one. I’m stoked so far. Also. Im a 9 guy. Gotta have the revs.

 

[mike lowary]

Nothing like the sound of a Harley air cooled v-twin singing at 8k rpms. Sorry. Gettin a chub

 

[TapRoot]

That’s awesome, I feel like I hear better results with the 9 beefed up rather than the 12, of course this is only my personal findings and not fact so excuse me if the statement comes off ignorant. I’d love to see a video and hear it if you ever get the chance, even though videos usually don’t do the sound justice I still think it would be cool. Thanks for sharing Mike and again, great work! ����

I was just looking at whats out there for 9's. Can the bottom end take the higher revs? I'm curious for a dyno sheet as well. Congrats and nice bike.

Its not so much the strength of the bottom end. Its because the 9 has a shorter stroke so by default it can rev higher. The 12 is 3.5x3.8 and the 9 is 3.5x3.1.

Got the break in done. Changed oil and took it out. First time I got the rpms to 6500 something terrible happened. Very very loud top end noise. Got it back home. Pulled the motor and tore it down. The valve seat on the rear intake valve is broken. Fml. I’ll post some pics tonight

Dan Dunn from NRHS is a standup guy. I’ve been a customer of his for a few years. Once we figured out what happened the first thing he said was “How can I make this rite”. I’m meeting him in Chicago in a couple weeks to take him the motor so he can rebuild it. My season is over looks like.

 

[konarider94]

Bummer about your luck but good to hear they are working with you. Interested to see the pictures.

Sorry to hear about your bike. I really wanted to hear how that 1050 kit worked out.

Dan is the man. I cant say enough good things about him. Youre in good hands!
