Nasty 110 Build

[838]

T-Man 660PS-2 at 10.6 in a 110" with a good head/intake/pipe. Large, broad, power.
Wood 408-6 is a close second....10.6 cr.
Our Facebook has the dyno info, on the use of the Wood cam.

I'd really like to see this 660 in a big cube motor. Have you done a 117-124 with this?

[Don D]

I have done what the OP wants with a cyclerama cam my $499 oem heads 1.9 / 1.575 valves at 11.2:1. 110 hd bolt on kit made 130/134.

Here's a Tman 660SM in a 120.  I believe the ramps were changed but the cam is basically the same.

I ran a 660 in my old SG 120r.
The numbers were nothing like that BUT it wAs a torque monster! A really enjoyable ride!

[Tail Ridr]

We did a 107 locally with the tts150 and it made 118/126. Fatcat and my Street Pro heads. Stock throttle body. High early torque.

Would be a pleasure to see the results of that build

2, 110's, 1, 117", and currently finishing a 113", and a 131", with those cams.
All were home runs.

I was advised not to do high compression builds in a trike.

We used to do it pretty regularly. Woods 9B always produced. There was one in the archives somewhere I did went 130hp/136tq sae. If it's in a trike though I wouldn't be shooting for numbers, I'd be focused on the torque curve.

[NHBagger]

Oh, I get it. Not looking for a cam that comes on late. Riding 2 up it's like 1500# going down the road. Tq should be 100 early and carry out a ways. Peak of 125 should cut down on the shifting to keep that mass moving.
Just because I'm on 3 doesn't mean I don't still like good throttle response.

[Hossamania]

Everything you allude to just screams 124........     

[838]

How often are you honestly hitting 6k rpm two up on a trike??? You can get big torque out of a 117" (bigger out of a 124"). If your not hitting 6k then go for a torque cam, head work to match, best pipe you can get and a solid tune. Talk to a head porter and a dyno tuner, they'll steer you right!!!

[harpwrench]

I'd pick a cam with an intake close to get your ccp down to around 190, and an exhaust opening around 52 with enough duration to get rid of the exhaust and heat. A 117 should have more than enough power to feel really good without putting up with pinging and hot legs

[Don D]

Agree with above but it will take more compression to hit the numbers stated at 110". At 117 this is a happy motor.  And lobe centers can be juggled to keep the overlap under control.

Bike is a 117" now at 10.2:1 (don't know if it's true 10.2 or not) op has not mentioned which type of heads or if they've been professionally ported...

Don, I'm curious to see how you would approach a build of this nature in a 117-124" ?

[Don D]

A 117" with OEM ported heads works real well, even at less than nose bleed compression, if you are not looking for that last bit of juice. Just like Harpwrench outlined. I like the 117 better than the 124 as they will take more abuse and last longer in my experience. Nothing wrong with a bigger bore 117" also up to 4.2". After that I would start with S&S parts and build up a custom big motor and go for it. The cost gets exponentially more. My best ring seal and bore consistency has been with ductile sleeved cylinders.

[NHBagger]

Looking at dyno graphs on the Internet to choose cams is not a good way to go about it. What heads are on this, ported 103 or 110, liquid cooled? Who did em? Specs? Exhaust- are you still using the small fullsac C pipe with small cores? Smashed crossover? What throttle body? (Edit- ok I see SE58) How did you get it down to 10.2 with a 117 if using 103 wet heads? How are you tuning it since it hasn't been on a dyno with the 117?

Took me a while to gather all the info.
Ported 103 wetheads. DVR did them originally for the 110 version. R&R redid them for the 117 with cr at 10.5 not 10.2 as originally told.
Fulsac CX with 1-3/4 baffles. Steve says I need to go to the DX with 2" baffles.
PV with TT, shop does not have a trike Dyno.

[sfmichael]

Definitely 2 - 2 1/4

[harpwrench]

If it were mine I'd go with an S&S HP103, at 10.5 I come up with 191 ccp. I would target that because of the weight and aero drag, and likelihood of having to put 87 octane into it once in awhile. Plus the road tuning. This is just what I'd do, good luck 

[838]

TR580 anyone?

[C-Cat]

838 I agree. It doesn't have that bite taken out of the TQ curve at 2500-3000 like the 590 PS2. 10.8:1 would be too much, need thicker head gaskets to be in range.

I just finished a 117 and we were hoping to use the 580 at 10.5:1. But at 10.25:1 the owner selected the s&s570 (it's in the graph I posted above... ) it rips, but I was thinking that 580 would do real well. We were also considering the tts-150 but without knowing the specs and with large valved stock heads I didn't want to mess with potential  valve to valve clearance issues. At 10.5:1 for the OP in a trike the 580 seems good without having to go into the +.600" lift range.
