S&s 107 Question

[jakace]

Anyone know the specs of a stock S&S 107. I'd like to know the approx. HP/TQ. I'm also not sure if the motor in question is a Super Stock or a sidewinder. Help me out, if ya don't mind.

S&S 107" powerplants usually will show 102-105 hp and 110-113 ft/lbs., from what we have seen.
Smooth configuration, and much more on tap if heads/cam/carb mods are addressed.

Hey, thanx for your feed back. I appreciate it.

What is a high figure for this engine? On pump gas with extensive head work (or a swap to worked over heads), modest left cam, say .625 and a good flowing carb like the PSI Genesis?

I reckon about 125HP/130 TQ?

S&S 107's are Evolution based engines.
They make a kit that will take your TC to 106", but they are not very popular a/c the short skirts on the pistons.

S&S build their engines for performance and realibilaty. They already have head work, a decent cam and a good flowing carb. They have done a lot of testing on their product, why would you second guess them?

We installed there v 107 touring engine into a early bagger. Runs good but not huge power by any means. The new V 107T is only 9.5 with a 585 cam. Made just shy of 100/100. huge increase over the stock 80 incher he had though LOL

Another crate we did for a 97 RK was a 113. bub 7 dual exhaust made 102 hp and 116 tq.
A 96 EPA crate engine landed at 76/93. These are in stock form. with out any engine modes other than tuning the carb. Ign was left un touched due to warranty.

they are not popular?? not sure what build you base that statement on

they have only been realeased for a month or so. all the S&S dealers I have talked to are not even able to get them yet!
as far as the skirts they are no shorter than the stock 96 ci that I took out. they are weisco pistons .030 less than the 107 pistons every one is using in there 107 builds. As far as I know I am one of the first to install the kit.
I can tell you the clys are very heavy much more than stock clys. the liners are as thick as a stock cly before boring.
they are very well engineered with zero deck height.

Well I base it on the fact that your the only guy I know who frequents this site with one. Do a poll. Hear about many 103, 107, 117 etc. And the S&S 106" kit has been out for years. S&S does make good stuff, but over the years a few of their parts have had issues, although they stand behind them, or did. The 106 piston isn't the first either. In the middle 1980's the pistons from their 86" Shovel kit for a while (made by TRW IIRC) had short skirts and they were soft. 3000mi and worn out. I know, went through 2 sets, 3rd set, installed and sold the bike.

they are brand new to the market is why I am the only one running it.
twin cam 106 4 3/8X 3.927 with wiseco pistons were just released. do some more research. They actually say 107 standard on the box
this is NOT the 106 4 1/2 x 3 7/8 kit
Evo kits have been around a long time.
Every S&S dealer I have talked to are waiting for them because the are new just released. The wiseco piston skirt in these kits are no diff than the wiseco 107 kits they are just .030 smaller dia. than those used in 107 kits. one dealer I talked to said that the wiseco 107 pistons could be used if at some point you want to freshen up . Bore .030 over. as far as I know there is only a .005 over piston available for the 107 or 98 bore.
The liner is the same as a stock 88-96 ci so no worry of heat issues on a bagger with lowers. This was the concern I had with the 107 ci because it is very thin when ya bore stock clys . I know a lot of guys are running them. I just thought they might be a little thin for my riding tank to tank all day and all night.

EDIT should have said .011 smaller bore than other 107's..
S&S =3.927 Hillside 107 =3.938

The 106 you are referring to is not the same as the new 106 jug and piston kit for the 96's. The one you mention is a stroker crank kit for an 88. You are mistaken.

S&S, as many outfits, will leak it out to the market that they have a new product.
Then they see what reponses they get, prior to pulling full-blown production runs of that product. That is why they are unavailable.
BTW, a worked-over S&S or our 107" kits we offer, will show 120-125 hp, and 125-130 ft lbs, street driven.

What clutches do you recommend for your 107's ?
as expected the stock setup wont hold the tq.
I have always used Barnett in the past.
but there are a lot of choices out there now. Kevlar? carbon?
I dont really want to spend the kind of money it takes to set up the VPC. Just thought I would go with GOOD CLUTCH and heaver spring.
I just ordered the 49 tooth clutch gear and will swap clutches when I install it.

OK, so theres 2 106" kits available. I was referring to one (early TWIN CAM) and strokerjlk the other.

The VPC seems to be the most inexpensive way to get a grip on that power.
