Hello. We would never try to insult anyone here. We love the community and have been building and testing systems for over 15 years. We understand that this seems excessive to some on this forum, but this is the reality of twin turbo vs. supercharger. Superchargers take A LOT of power to turn. That equals lost RWHP. See below a comparison of the same car with 21 psi with the supercharger vs. the same 16 psi pull with the Hellion street sleeper...same dyno...same tuner...same elevation etc. Just simply a swap from a twin screw to a Twin turbo. In fact, the supercharger had 23 degrees of timing to the 21 for the turbo.I am with this guy. These #s are just Yuge!! Us Mustang guys are not all idiots. Please stop this madness. Should I pull my JT Vortech for the sleeper kit? Absolutely. But please stop with the exaggeration. It is a insult to us guys. We went through this on another thread and now here we are again.
What problem did you see? This customer bought the kit right from us with a cost of $6395. He already had a built motor, injectors, and fuel system. After an install at The Dyno Edge it went straight to on the dyno and he is daily driving it now.I don't have a problem with the dyno numbers. I have a problem with making it seem like their $6395 price tag got this guy 1,000 HP.
Without isolating any certain company, we can just say it is a very common unit spoken about in this forum.What supercharger? over pulley'd excesive intake inlet temps?
This vehicle was tuned by Chris Groves at The Dyno Edge with both combinations. The customer had purchased the original supercharger and spent hours upon hours on the dyno trying to refine it. In the end the swap to a Street Seeper kit is what was needed to made this big gain.I think I saw a video of vmp cracking over 1k h/p with their mustang with the gen3.... may have been more? maybe the gen3 wasn't properly tuned on yalls dyno?
Ok. Ignoring the snarky snide comments, School me on this.Did I really read some people say “8.3lbs is 8.3lbs” it’s the same hahaha.. come on here talking mess and ignorant themselves.. here my focus st made 285whp on the stock turbo e30 at 23psi.. after the “big turbo” swap for a GTX2867R gen2 at 23psi it made 355whp on e30. 445 on e30 with 70/30 meth at 28psi.. but no.. just because they read the same psi doesn’t mean the flow the same air..
let me edit and state it wasnt so much to the original guy that stated number more so to the others calling bs. Yall dont understand the power it takes to turn a SC and then how much more efficient twins are at making that boost. how much more air they flow
The supercharger isn't a restriction. The boost # is the pressure after the supercharger. I would venture to say the biggest gain would come from the reduction in parasitic losses.The restriction isn't the same though. You've removed the supercharger from the intake path. The supercharger effectively is a restriction. Now you're making 16 psi with turbos through a traditional intake manifold with much less restriction. So therefore you're flowing a lot more air to make the same psi which is where the increase in hp comes from at the same boost levels. That's my thought process anyway.
I would agree. But 370 horsepower worth? To me, that seems like a crazy number! I’d like hear from the experts as far as truly what sort of pumping losses one can really expect from a supercharger.The supercharger isn't a restriction. The boost # is the pressure after the supercharger. I would venture to say the biggest gain would come from the reduction in parasitic losses.
great you said this, this is what i was taught a long time ago.Picture of you will blowing into a McDonalds straw. No matter how hard you blow (pressure) the size of the straw itself is the restriction doesn’t matter if you blow or a child blows through it, the volume the straw - engine - can allow through is the same. If the man is the turbo and the child a supercharger, ultimately the man can exert more pressure than the child can, but the straw itself is the restriction. The straw or engine doesn’t care who or what is pumping the air through, it only knows the exact amount that can get through it. How does the flow out the back of the straw increasenunless the pressure pushing into the straw changes?
