An S&S .570 in a 107" @ 10.0 cr, with a good set of heads, exhaust, and t/body tuned correctly, is a cool running, reliable, all around STRONG combination.
In a smaller engine,(95, 98") that .570 is not as agressive off the bottom, but in a 107", it is.

That looks like a fun ride. If building a 107 with either a SE 58 tb or HPI 58 Tb what would one suggest would do to that curve? Would it carry out farther than the 4500 rpms or is that where that cam signs off?

 

Yes sir. P/P heads and 10.5 pistons in a 96 to 103 conversion.

 

I have a 2010 SG and put in the Head-Quarters 107 kit last September, it comes with the HQ-TC-575 cam. It dyno'd (SAE 5) at 114.8 HP and 121.4 Tq, VERY pleased with the results.

That sounds like the type of package and performance gains I would like to have. Can you please give me more information on the build and if you have a dyno to upload I would really appreciate it.

 

Sure thing, I'm at work right now (night shift) so it'll be a bit before I can post it.

 

Ok, usually on the forum at least once a day. Thank you...

 

Im sure Scott will chime in tomorrow morning. This is one of his builds. Im sure he has some tricks up his sleeve to make it even better. Seems lke the 6 cams work in just about everything.

 

RottnRam, here's the Dyno of my Head-Quarters 107 build. The 'before' numbers are from a 255 cam and 103" upgrade kit the dealer put together when I bought the bike with the added SE Heavy Breather, a Drago's Dragula 2-1 exhaust, and a PowerVision tuner from Fuelmoto. On the recommendation of my builder and tuner (Lonewolf Performance) I added the HQ-107 kit which included reboring the jugs (had them port the heads at the same time too) and the HQ-TC-575 cam, compression is 10.5/1. The bike now has plenty of giddy-up and is a blast to ride.

 

Looks good and thank you for the dyno and specs
