JJ's 914whp ALPHA 9 GT-R, the most powerful ALPHA 9 to date!



A long time ago NAGTROC member RENNtech (JJ) approached us with a dyno appointment. Sadly the day of his appointment we lost power and failed to contact JJ in time to let him know not to make the long drive out here. Obviously upset JJ left AMS with a bad taste in his mouth.

Fast forward about a year later and JJ was looking to make some waves with his 2012 GT-R. He was looking for a very streetable but powerful package. JJ actually contacted NAGTROC's very own VegasGTR (Sam.) Sam helped convince JJ to give us another chance and to work with me on a build being that he was a part time Chicagoland resident. We were grateful for the opportunity to make up for our failed previous efforts.

Well this story has a happy ending!

I worked with JJ on taking his currently modified GT-R and converting it over to our newly revised ALPHA 9 package. In addition to our basic package we upgraded JJ to our full 3.8L Long block with ALPHA cams, ALPHA Race FMIC, Akrapovic exhaust and a tried and true ShepTrans stage 2.5 trans upgrade.

To say the result was successful would be an understatement.

On pump gas Chris was able to extract 820whp and 711ft lbs of torque
On race gas Chris pulled out a mind bending 915whp and 826 ft lbs of torque!

The race gas numbers are officially the highest we have ever made on our ALPHA 9 package

JJ, we know that you had a lot of choices when it came to upgrading your GT-R and we are honored you chose us. We hope the car turns out to be everything you had hoped it would be and wish you years of problem free, safe and fun operation.

Have a fun drive down to the sunshine state :)

Nice numbers!
Congrats to JJ and AMS
Congrats! Good story too!
Congrats JJ on the project. Can't wait for some 9 sec passes :shiftdrive:
Nice numbers indeed. I'm curious what boost levels each were achieved at?
Thanks,

Dave

Plus 1 both on pump gas and race gas.....
Pump gas numbers were about 23 psi
Race gas numbers were about 28 psi

Eric
Thanks. :)
Eric,

Congrats on the numbers bro!! Any concerns with that much torque and the tranny?
No we took the appropriate steps on that trans build to keep it together.

Pump gas numbers were about 23 psi
Race gas numbers were about 28 psi

That's about 20hp and 20tq per psi of boost! Very nice!
Very nice numbers. Congrats!
congrats JJ !! awesome numbers.. lets see some 1/4 times.
Very nice.Let me know if your ever in the West Palm area and go Gators.
URT is great stuff. Congrats to JJ and AMS!
congrats guys!
Thanks a lot everyone ! I just got back from a spirited drive around the great city of Chicago. Obviously, traffic is always an issue here so, I couldn't get too crazy but there is no doubt the car is an absolute beast now ! AMS really delivered a quality build and working with Eric was an absolute pleasure. He provides as good of customer service as you will find anywhere and is a real asset to the company.

Hmmm.... and no call or txt to me to let me know the car was done, or invite to see what she does at the strip.... hmmm.... Count my feelings hurt.. :furious:
would love to hear more about how it drives compared to stock ie moving from a stop at street legal speeds etc
Damn JJ, that's very impressive!
Another well put together high power build from AMS! Well done, guys!
Nice numbers indeed... Looking foward to track times :)

You better check your phone . . . . . :wink:

From the limited seat time I've had, I can tell the tranny is noisier than before and the lag is a bit more noticeable too. Overall, I'm very happy with the drivability, especially considering all the extra power.

lol. . . I went to the only track open around here today. The surface was complete $h!t and that's putting it politely. The prep itself, was non-existant. Unfortunately, I never made a full pass without lifting the throttle. I was on street tires and got a ton of wheel-spin/hop. I used LC5 on my first run and managed a 1.78 60' and trapped a dismal [email protected] My previous best before the build was [email protected] so, I'm pretty sure there is a little more in her. . . :)


Here's the vid my girl took. You'll have to excuse her commentary. . . lol
