it all depends on the blower, the rotrex's don't quite switch into full on hairdryer mode like the vortechs do at high boost that is why they typically run more power without popping.

I posted this a week ago but didn't get much response. But this dyno was done at Stillen. Some things to consider as you can see in my post. 3rd gear pulls and no fan. My HP numbers seem on track considering, but my TQ numbers seem low. Did you ask what gear they were testing in? It's hot as balls in SoCal so that doesn't help. Did they use a fan at all? Everything adds up.

Not on the Stillen canned tune but 416whp is doable with a custom tune, mines 418whp with the 8lb pulley and Stillen cat back exhaust.

The canned tune sucked on my car and I don't think you will get that 416whp on Cali gas.

Wow, when you posted that I didn't realize it was at Stillen. Maybe they aren't changing the canned tune because of the CARB stuff you have to meet?

And 3rd gear pulls?

You WHP should be at worst 400 and QTRQ should be right around 300. 3rd gear is the wrong gear.

We just changed the exhaust and the car feel completely different. Why don't you come by and drive it and see. We will be dynoing tomorrow and I will post results.

We have been changing the canned tunes recently. Any supercharger kit after April 2014 has our new tunes. We had an IPL in Florida make 429 whp with a stock IPL exhaust (auto).

These are 3rd gear pulls because 4th gets going too fast.

I'm glad to hear the canned tune has changed!

I'm a Stillen fan but the canned tune really let me down! Glad to see you are working on it!

Yeah i talked to a few tuners some of them were recomended in this thread and they were saying the new tune were way better
Hoping for some good news from you guys soon :driving: :tup:

as I am also , But the canned tune I had only made 40 more WHP than my bolted tune. I'm just curious too , why did you emphasize smog legal tune ?
Just because we get a custom tune doesn't mean it's not smog legal. I got my sticker on my 412 WHP custom tune.
Get work in changing the canned tunes

93 octane

Also please don't get me wrong I have every performance part that stillen makes for a reason. I love my stillen set up and I'm glad to hear that the tune and the exhaust is better. Just sux that I bought probably the last kit before you changed it. I bought mine the 3rd week in April this year lol figures

I heard Stillen was working on the Supercharger system that will make more power. Is this what i've been hearing? A better tune?

To be clear, I'm not bashing on Stillen in my thread. I was just pointing out how they dynoed and the differences to what I'm used to seeing. Everyone there is really cool and helpful. I will definitely be going back to them. Customer service goes a long way for me and they were incredibly courteous.

I am baffled by the lack of a fan on the dyno though. Especially when the car shows heat soak, this would help reduce that and simulate a closer to real world experience. I'll probably bring it in to dyno my car with my new exhaust and HFC. Since info is lacking on the Ark Grip exhaust, figure it will help the community.

No, they are working on a kit to make more power also.
