Has anyone tried a 6670R WITHOUT dual fuelers, or is that a complete waste?
Yes, plenty have them with a single pump. If you plan on more in the future it's ok. Otherwise the only gain will be sound.
i think its a good bit more turbo than stock fuel could use, but maybe morgan can confirm.
Stock "2015" fuel is good for around 600 on most dyno's. You can over turbo it and still only gonna make that same power. So yeah.
I can see them making similar power since both provide more air than the fuel can use, but I wonder if the 6670 would be more sluggish and slower spooling.
Similar power. Both spool well. But you do give up some cruising egt's and tip in response with the bigger charger.
i'd say to a point yes, but a turbine is a turbine. the barder will spoool slower. i think if you dont have a plan for dual fuel in the immediate future , its alot left on the table in spool and money .

So once the duel fuelers or other system that someone uses to up the fuel for the 6670; what is the hp gain over the streetmax R? If that makes sense? So if you can get w/o fuel 650 with the SM-R, is it worth the extra $1700 for the 6670 as well as $3500 conservatively for duel fuelers to only gain 50-100 at most rwhp? Thanks!
The dyno's we've been using are showing 540 stock 15 charger and pump, 600 with 65.5 and 650 with 65.5 and added fuel. On average.
6670 and fuel probably good for 700 ish. Built engine ported heads bigger injectors we've seen 750.
If that helps.
The StreetmaxR should be in the 650 range with fuel, or roughly 50 more than on '15 fuel. The 6670 should get you to about 750 with fuel. If you're buying the extra fuel anyway...may as well go with the 6670. Just my opinion, but I could see a case for staying with the StreetmaxR, since it won't make enough power to satisfactorily destroy internals and the 6670 is pushing the hell outta that limit.
Yep.
With aggressive fueling and poor driving habits, either can spit rods... But then again so can a s366 or stock charger.
"with fuel" is a very loose term. Not gonna hit 750 with a 6670R on stock nozzles...
Not on most dyno's. Some on the east coast may..
Morgan, or any guys that are just running a StreetMax and '15 pump, are you seeing any issues with other parts? Thinking this is where I'm going with my truck over the winter. Don't want a crazy hp truck, just a nice reliable daily driver. My truck currently is fully dereeted and canned tunes on the SCT.
Thanks for any help.
Only real "weakest link" is the Trans. Which at some point will give up. But we have plenty of fixes for that!
