Funny that you say the D8T was fast with the on-road motor. The C6USA actually uses an on-road crankshaft with the standard C6 piston and sleeve and it is a beast in a truggy. The on-road motors are designed for all out power for a car with a TON of traction so it can be a pretty violent power band in an off-road car.

I stumbled onto a C6 USA and a 192/2045 combo for 50 bucks. It needed a p/s/r. I didn't even want it cuz at the time i only ran speeds. So i rebuilt it and had it massaged by Uriah and all i can say is it's one bad ass engine. Haven't ran it much since break in, enough to be quite happy with it. Too bad they aren't made anymore. When i get bored with my EB Mods nova fms the RB is going in. Life is good.

If you have the patience to tune the jp3 in im sure you can make it work. The s5 seems to run a tad hot no matter what pipes on it to get good power out of it that i found other than 9886 or 086. Next step is runtime and not running too lean then too hot. My guess is you will get 8-8.5 min a tank in truggy with jp3.

The 086 with short double bend is awsome for buggy but may lack torque a bit for truggy although not sure cause iv never ran an s5 in a truggy. To be honest i can see the s5 with jp3 in truggy working just fine...just watch temps.

With the rb pipe in buggy i was never satisfied. temps were hot and runtime was low. Actually about the same as what i can see a jp3 maybe being yet i never ran a jp3 on an s5. I did try a jp4 and it worked well. I tried a jp1 for a couple tanks too after a freind(quite a while ago)said put one on it cause its an rb and jp1 ran well on his c6 haha. Well the s5 and c6 are totally 100%diff

The S5 with 086 pipe will work fine in truggy, you will not loose any torque, it'll scream, years back ,I ran the GO 5 port with the 086 pipe, in a truggy, it used to pull wheelies on power!

ok cool il try the 86 pipe on it than , it saves me money lol.
so il still have enough bottom end for the truggy? the 86 pipe i have has the, stock header on it im not sure if its a long or short header. a longer header will give you more torque right?

correct. long header more bottom and short more top

You know nothing

ok i forget to mention that i race ,on a big outdoor track that is techinal .
im not sure if the 86 pipe, has enough torque for them kind of turns .

i whould think the jp3 whould. since its a combation pipe.
so your saying the this, engine will run hot with the jp-3 pipe?

The 086 pipe is your best choice if you cannot get the RB 2045. I personally ran a 086 pipe on the S5 and it worked well. The Jp pipes IMO are not suited well for any RB engine and yes they do run hot with them.

ok cool . do you think though that, the 86 pipe has enough torque for the truggy? at the track i was talking about that i race at?

Ya your fine my home track is the Nitro Pit which is big and technical. I ran the S5 in my Xray Truggy for a couple of weekends and it was fine. If you feel your not getting enough punch mess with the clutch springs/shoes until it feels good.

ok yea i seen the nitro pit is a bad ass track, and the turns are a bit similar to where i race at. yea im running a all alum, clutch setup so i guess i should have enough punch plus, im running a stiff clutch springs also . not the stiffest though.

Yes, but I try nothing also!

It is too bad they aren't made anymore. I have not tried the engine in buggy but in a truggy it flies and still goes 12:30-13:00 minutes on a tank. I can go a little longer with the standard C6 but the extra power is nice!!

They are not made, but they are still available. All of the parts are interchangeable with the B9, which is still made.

We are talking about the C6USA, this engine came with a Rody modified crankshaft, and head button. It's MUCH more than a C6 or a B9 as far as performance is concerned.

Everything is interchangeable but putting a B9/B10 crank in it will really change the powerband of the engine. If you have the USA engine already and the crank is in good shape drop a new piston sleeve and rod set in there and be set!!
