Thanks Tony... appreciate the information on how ECU Tek differs from Uprev!

 

500WHP may be possible if you convert the kit to A-A with larger piping. I'm currently awaiting dyno #s from the 370z's that swapped over and then will decide if I want to go that route or not.

 

I sure miss those Stillen SC days with my G37.

 

Great read... now comes the tough decisions. Do I risk the reliability issues and go FI. Car was purchased to be a DD... FI or bolt-ons. @ANMVQ are you happy with your choice to return to NA?

 

Right now I say i would be looking for reliability over power but once I have a taste I know it will be tough to "settle"

 

Nico-derm I have had mine for over 10,000 miles and over a year and I have had no reliability issues. my care has over 80,000 miles on it and runs like a champ. You should be just fine with the stillen kit, problems arise when you try to surpass the capabilities of the kit. I can tell you that I would never turn back from my blower install. I love it and it puts a huge smile on my face everything I get into it. It will not be something that you regret. not to mention you will never see the taillight on a SS Camaro, 5.0 gt mustang, challenger, of 3 series bmw again

 

Have any Canadian or Northern US guys installed the supercharger and still driven their cars in winter? if so was the car still manageable or will i need a winter beater.....

 

I've been running mine in NY for a year with no issues so far.

 

I am happy going back NA. I'm looking to finish off my NA Bolts ons with "maybe" headers :/ . But o have no worries of the motor or trans letting ( another guys tranny just went by by with the Stillen kit). It just luck Imo depends on the tune 100%. But I am happy being NA. For me just too much risk. 10k for the kit installed and tune with a high chance of something happening.

 

You miss the supercharger. Search your feelings, you know it to be true.

 

I may have to reread this thread incase I've missed it. Has anyone built their block to max out the power of the stillen supercharger? On a stock block its around 440-460. Has anyone seen where these kits peaked at? Any difference with e85? ECUTEK?

 

There's a 370z with a built block, which is running his well over 500whp after e85 and A-A swap. There's also another running 500whp on stock block. I can't see a need for building the block, especially since the trq numbers are so low. I have a feeling a lot of these blown engines we have seen in the past are a result of fuel starvation or IATs. I'm upgrading to a fuel return system and flex fuel whether I change out my piping or not this winter.

 

In cold weather you make way more power due to the denser air. That will not be a help. I drove my G37S with bolt on's (NA) for one winter in Edmonton and it was a very sketchy experience. Now that I have the Stillen V3 I wouldn't dream of winter driving it. I got a Jeep as a winter beater

 

Yeah I know about those 370z's ... And about the air to air setup... Was seeing if anyone here took the kit itself to its limits and not just the stock block... Heard the supercharger is good to about 550ish but no one has actually gotten that close. Also haven't seen much e85 or ECUTEK usage over here...

 

I'm pretty sure the 370z with the built block is running around 540whp at 13psi. I should be swapping over to e85 in the next month. It should help with the IATs whether I redo the piping or not.
