Hey Parish, I was just looking through my September issue of Truckin' magazine when I came acrossed that bad *** step side with the 6.0 liter ATI supercharged 200 shot nitrous injected Silverado owned by Dave Ransom. I think we were oogling about this truck before. Anyway, the very last paragraph says, "...rumor has it that by the time you read this the engine will have Stage III Z06 heads and a Magnuson supercharger pumping out nearly 1,000 hp!" It sounds to me that this is the guy that you want to talk to. I don't know if he frequents this post, but I think one time he did "chime in" when we were all talkin' about how bad *** his truck was.

 

hmm, well, if you were able to get 550rwhp out of the radix and sprayed another 450DP nitrous then sure i could see it.

magnasun probably makes other bloweres i would think. whipple has a 3.0L blower, maybe he is going with some big dog blower.

 

he posts under 4GoNotShow his truck is roll caged back halfed ect....he was supost to post dyno results of the ATI setup but never did....bad *** truck

 

here's an example for you guys. my P1-SC made 13 PSI with my old stock 4.8. with the 408, it only made about 6 PSI at the same RPM. i believe your answer would be related to the actual build of the motor and how much air it will actually flow through it. a radical cam will blow off more of that wonderful boost than a milder one. i don't have the e-mail anymore but i discussed it with them and we determined that my boost needs vs my build would develop too much heat, even with the intercooler.

it sure is a damn nice blower though.

 

I had a discussion about this with one of the guys at Magnuson today. The max blower speed that they recommend is 14,000 RPMs. Max horsepower will pretty much depend on the combination along with tuning and octane that will be used. One of their trucks has made between 550-600hp. This is with a 6.0 motor that was built by LPE. He referred to it as their "drag truck" and said that it's not as streetable as normal. Their kit uses a 112 head unit which is the same one that is used on the Lightnings. They've heard of some of those trucks making up to about 600hp.

Most guys won't reach the limit of the Radix, but then there are the guys on LS1Tech.com

That is the Max RPM quoted by eaton on the blower........

Lingenfelter has been spinning these blowers up too 19,000 rpm for years now with no problems. Although Eaton has not posted any testing past 14,000 RPM's, it is common knowledge that 18,000 RPM can be done and is done on regular basis. The Lightning guys have been doing it since 99!

 

I know its pretty easy to get 480RWHP with a C5 M6 with just headers and a small cam. Thats with less boost and no intercooler, less cubic inches ect..

But a Auto would eat up another 40RWHP on the dyno.

So far its all talk and no Dyno Sheets

 

yep it's all up to you

 

FunGuy?

 

Yeah, Brian, where is that dyno sheet you promised, oh, how many weeks ago....???
