I wasnt that patient, LOL

 

Glad to hear that things are going well. Those are nice numbers BTW.

 

Awesome. I have an 11 coupe awd with a stillen sc installed - took 5 weeks for the dealer to put in properly, but well worth the wait! I'm wondering now though what the hp is and how awd impacts the output. Anyone know?

 

I just bought my 2009 G37 Journey a couple days ago. But the previous owner had the techs at Infiniti in Louisville, KY order the Stillen SC kit and install it and they had one tech in there who was quite knowledgable and did the whole install. The tech went with the customer to Chicago as well when they brought it there for AMS to do the UPREV tune.

The car will hit 9psi. I know at 7psi, the car made 473whp and 481whp on two pulls. I'm not sure of the exact numbers at 9psi, but I know it's in the 500+ whp neighborhood.

The car is in my garage for those who want a full mods list.

 

ANMVQ is going round and round with the dealer . His motor went BOOM and hes now fighting with them over the warranty. He has a thread named BOOM.

 

Wow good numbers, would love to see the dyno sheet! Could u post it up?

 

I knew I would be asked for this. I'll try contacting Grant (prev owner) or AMS in Chicago and see if I can obtain the sheet from one of them.

 

I would be interested in seeing that sheet also. I make just under 400 whp at 7.2 psi here in the Denver area. No headers but I can't see headers adding 70 to 80 whp.

 

Very true ^

 

Who tuned you?

 

Welcome to MAC Autosport

Custom tune, not the Stillen canned tune. That is my car on the home page of their website.

Here is the link to my thread for the install

I also hit 475whp on 91 with no headers but now i am on e85 hitting 550whp plus climbing....

 

I am guessing that you are running more than 7 psi. Did you have to chnge out anything to run e85? I have read that most newer model cars should really have no problem with e85 but some older models use materials that won't stand up to e85 which is more corrosive to the fuel system.

 

yes, i have changed the cogs like ANMVQ, injectors, fuel pump, return fuel regulator, spark plugs, blow off valve. Keep running out fuel on the top end, so my next step is to go to a 400 walbro pump and maybe bigger fuel line.
My goal was to pass the 550whp mark and its there. If get more fuel i be closer to 600whp, witch is impressive for a supercharged system for any off those numbers.
