If we could set the sc back and have room for a nice big filter then the V3 would be making 600 all day on our "non stroked" VQ's.

They're going to use my current motor and trans to test the stage one kit vs the stillen kit since I already have the stillen kit the way it comes from stillen. Then they're going to install my new motor and trans to reach for the higher numbers. They're doing that so people can have an apples to apples comparison of their kit vs the stillen kit.

I can't wait to hear that whine!

And we are excited for you! But with all due respect, you can't really claim a record you don't have yet, especially so with a builder that doesn't really have a very successful history in this community.

Feel free to write your name in the record books after you've put some miles on your beast past that first glorious dyno pull.

Im honestly not sure thats actually a really good question ill have to ask but it would seem likely they would be the same or very similar. Besides aesthetics like powder coating and titanium dress up bolts which i chose to do

Jesus christ. ..i never said my car had the record. ..i said my car SHOULD have it when its done in a month or so. ..why do i get the sense I've unintentionally butt hurt some people here

nomodsjk · 05-30-2017, 03:35 PM

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

Have you ever tried putting a vacuum gauge on there to see how bad it is?

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.

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.

Sorry! My B, no need to cry out to the Lord. No butt hurt here...

I am pulling for you!

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

phunk · 05-30-2017, 05:04 PM

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.

nomodsjk · 05-31-2017, 10:27 AM

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

That's pretty much the case. A lot of us are sitting here with fingers crossed you get what you paid for and it's reliable.

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)

Yup... I got all the love in the world for you, nomodsjk... but I don't have much for this particular builder. Looking forward to the results, though!
