Highest HP out of a supercharger set-up

TopgunZ

I have confused things a bit:

In the regular kit it isnt the filters per say that are the bottle neck, its the intake track. In order to get a boot on the sc, since it is placed so close to the rad shroud, they put a restrictive boot on it that has about an inch of clearance from the blades.

In going from that boot to the direct filter I use in my kit (Air to Air) then it opens up the sc to breath better. However, the supercharger would LOVE a bigger filter than the one I provide but there just isnt the room to do it.

This is why I am looking at building a whole new setup using the V3. Its capable of 600. The stillen bracket placement of the unit is not. Well, unless you want to run without a filter.

I have dyno sheets of my setup with the filter on then with it off. Back to back runs. Ill post them up when i get home to take pics of them.

I just unpacked the kit to get ready to install it on that car here and NOW I see what you are talking out. L.O.L. what a piece. Definitely will be putting some thought into possible ways to avoid using that particular component.

It's a good thing you and Topz are putting thought into it.. It seems clear that Stillen didn't devote much.

Having been in the industry a long time I can tell you that almost every forced induction kit I have ever installed was more of a "Starter Kit" than advertised. Having somewhat recently made the executive decision to not sell our CJM turbo system parts in a "complete kit", it is easy for me to relate with why it is like this.

There is really no end to it. You can just keep going forever and ever. There has to be a point where a product designer says ENOUGH and hits the release button. Each manufacturer has to decide where they want to draw that line. Sometimes you are better off getting less as the consumer, because you can use that leftover money to customize to your own preference.

When I first got started in the industry around year 2000, back then MOST F.I. kits would without a doubt blow your engine in short time without lots of improvement, especially in the fuel and tuning department. They just focused on getting you the hard parts that you need along with the BARE MINIMUM to get the car to drive down the street.

You also have my A2A kit in your hands that is going on that car right? You ditch the suffocation boot and use the direct fit filter I include in the kit.

Yup. I didnt realize you also included parts for the intake.. I figured it was just the intercooler kit.

If u put the same amount of time money and effort you'd be looking forward to seeing those kind of numbers too. Im not selling the kits...im building my dream car and yes i have high hopes

TopgunZ

Actually, guess i had it in my phone. See how there is a "hypothetical" line after I had belt slip? It was putting me into 600's. Its hard to see but that next line bar is 620whp.

Is that with the impeller upgrade? How many lbs of boost were you running when this dyno took place? Those numbers are amazing

Trust me if something goes wrong with this build I'll be the first you here from especially after spending 9 months and a small fortune on a kit that's brand new to the market. I knew there was some inherent risk involved but i didn't want to do the same thing as all the other guys via the stage 3/4 fast intentions kit so if something goes wrong and it doesn't turn out as planned ill be the first to admit it but for now i do have really high hopes for around the 900whp range. If the kit ends up not working or worse yet not even produced then I will go with the tried and true FI kit but im really hoping thats not the case because I think its cool to be a part of a "first" thats the main reason I took the risk. Breaking anyone's record was never on the list of motivating factors

Has the world ever seen 900whp from a supercharged 6 cylinder? I think that would be pretty cool. Never personally seen that. I guess its 2017 and someone has probably done it, but either way it would be cool.

Its going to have the displacement of a small v8...just under a 4.3 so yea im hoping for those kind of numbers with 2.9 liters on top of that with the right fuel set up.

phunk

Well I think your goal is most likely obtainable. It may or may not have some additional challenges, but I am sure it can be done. That said, even with a 4.3L you will be at some notable disadvantages vs a v8 4.3L that tried it. I think that your goal would be more accurately compared to a v8 acheiving 1200whp with a larger whipple. The perspective I am looking at is that you have 2 less intake ports and 2 less exhaust ports to work with, less X/Y plane cross-section to fit your intercooling (due to a shorter engine plus a narrower 60 degree valley vs 90 degree), and of course less pistons and rods to spread the work out on. Also a 900whp V8 will generally be able to do this with a very stock-ish short block, where the stroked and sleeved v6 has introduced a host of potential complications that could become hurdles.

(So, I think you can get there, I just might not expect to see it on the first tuning session)

You're right obviously I didn't consider that before posting. Back in October when i first started buying parts for my high hp goals i spoke with mike about what i wanted to do and originally we were going to go with the tried and true FI kit stage 3 to be precise so i bought his stroker kit he had for sale and he recommended bobby for the engine build and i agreed. After a couple months into the build the idea for the whipple came up and I mentioned that I always wanted a high hp sc system because I wanted to be different. I didn't want to just copy what others were doing and i prefer the power delivery of the sc. From the start i said that for the money I would be investing I would want around 900whp and anything less wouldn't make sense considering what the FI kit has been proven to produce with similar modifications. I knew the whipple kit would be a bit of a gamble but I seriously hope we get close or yes I'll be bummed...even if we get 850 ill be happy after all its gonna be hard enough getting all that power to hook properly. That's why I dropped the air ride and went with the robbie spec kw's, os giken diff, dss axels and every spl part made for our cars. Also i thought anything over 850-900 would just be dyno queen territory and unusable and i really wasn't interested in breaking any power records. What I really want is the fastest car not the most powerful. So yea after 9 months and more than a brand new nismo invested I have high hopes as I believe anyone here would and everyone here can believe me when I say the dyno sheet will be posted either way. Im counting down the days like a kid on the 1st of December and im hoping santa brings me my freaking power goals...

Im going to assume all this love im getting has more to do with the builder and not so much my car in particular
