Our truck is up and running again. Still making 415hp/451ftlbs. Truck feels really good, we will be taking to the track soon. BTW, we are spinning the blower 18,000rpm. We are seeing a solid 5lbs of boost, not enuff! I have given up on the magnacharger ever making more than that. We are still deciding what direction we will be taking the truck from here. Either ATI D1 or turbo, don't know yet.
Thanks
Thanks

any idea what this guy is spinning his blower too?

I think L's are the best guage of what the 112 can do. They've been out for a while, and the guys have been pushing them to their limit for a while now. If the 112 was capable of 700, I think they'd be there. 600 I think they'd be there. They have great flowing 5.4's into the mid 500's. Who knows what more cubes would do. I say you could get close to 600, but again, that wouldn't be practical. I think anything over 500, and you're working way too hard for your horsepower.

As many of you know, Chris (superfords) drove up from Virginia Friday night for a Saturday dyno session here at PSP. Chris is a great guy, and his truck is just awesome. Gotta love the sonic blue as well. Anyway, I'd like to think we made some great progess on his tuning. We did him a pump gas street tune, a 100 octane race tune, and a 150 shot nitrous tune. Here's the results..
Street tune - 525hp 597tq SAE with mid 11s A/F
Race tune - 541hp 606tq SAE with 12.0 A/F
Nitrous tune - 669hp 834tq SAE with low 11s A/F
And for those of you into STD numbers
Street - 539/613
Race - 555/622
Nitrous - 687/856
Chris' truck is making some power baby! Don't forget that this is a mild combo too. Extrude honed heads (not CNC ported), stage 2 cams, ported Eaton seeing about 16-18 psi if I recall correctly. The nitrous was using a 150 NX shot at 1050 bottle pressure.

With boost it's even worse depending on static compression and such. There are just too many variables unless you are comparing 2 identical vehicles.
looks like around 540 rwhp from an L via BlackBlown.

I've got the Volumetric Efficiency/Inlet Flow Charts printed out.
Am I right in thinking the Inlet flow is the chart of interest?
I've got the graph and extra paper to extend the curve......

the compresor charts tell the story. people pop in here and say sure it make 450rwhp on a 4.8 so it can make 600 on a 408 but it just doesn't work that way. check them out. prety interesting

Yep, extend the inlet flow curve. It's not linear as you can tell the flow delta starts to decrease as the rpms rise. When you find the extended CFM multiply it by .69. That is a quick conversion from CFM to flywheel hp. Then extend the hp required to drive the supercharger graph and subtract that. Also notice that past 10-12K the heat delta graph starts to rise quickly. That will also reduce the output.
The math has been done before but, I forget it so let us know what you get.

We are talking street trucks, yes? Pump gas I'd imagine?
where do we draw the line?
seems like BigHP! might be just what a Radix is capable of

you are right about what is big horse power. that number will be something diferent to everyone. the only reason i even get involved in the radix discusion is because i wanted one. they are such a clean install. after finding and crunching the numbers i found out it wouldn't give me the horse power i was looking for. at the time there were no turbos so this was quite a delema. a non intercooler whipple(that also has a limit) or an intercooler radix(with a lower limit) or a procharger with a higer limit but belt slip issues and weak low end. no good choices there for what i was going for.

I hear ya bro.
I've followed your changes closely, like many others.
Did a search a while back on all your threads started to get the full parish history.
AC and Rear Bumper was referencing the direction/progress of your truck, which I think is a mostly headed towards a non-street type truck. Not that your not crazy enough to still drive it on the street, just that most would choose not too. Much in the same way, you say, i dont think it would be wise to push a radix to 500rwhp on a daily basis on pump gas.
I understand there are alot of Radix owners/lovers here, likewise, there are plenty of non radix owners/lovers. When someone drops in on a thread and says the Radix can't do 500rwhp thats cool, but why not back that up with some useful info and facts. Especially if that person has some expertise that would greatly enhance a technical exchange.
When you mention a thread getting ugly by the radix guys, maybe we are tired of people telling us what we can't do with our beloved SC and then dismissing any further comment or question as irrelevent. For a long time people on this board were saying 500rwhp was not possible with the Raidix. Now, guess what, we are starting to see it IS/WAS possible.
I believe that is one of the reasons BlownChevy started this thread.
Just so everyone knows, I truly respect everyones point of veiw. All I ask is if your going to say something like "the Radix can't do 600rwhp", stick around long enough to discuss it a bit. Or at the very least just admit you don't really know...............not saying you don't Parish.
hmmm.

Lets say you are at 500hp with a Radix setup - spun just about at its peak. Throw on a 100 shot. The motor is then making 100+ more horsepower "on its own" (via more oxygen in the combustion chamber). Does this extra power cause the blower to spin even harder and the motor to suck more air through the rotors than the Radix is capable of? Or another way of saying it, is the nitrous hp going way over the efficiency threshold of the blower - causing the blower to be a limiting factor w/nitrous at that hp level?

I believe it can only enhance the capacity of the air pump.
In other words, nitrous makes for an ultra dense charge for combustion. Apply this to the air flow capacity of said engine, end result big HP!
the blower will not spin harder, it is mechanically fixed and dependent on engine rpm.
