Alpha 9 Perfect Street Car
The car was sent in for surgery at the beginning of February and the car was ready for break in by mid May. A couple weeks ago I finally was able to pick the car up from final tuning. It is making around 835whp/725tq. @ 27psi on E85 and on pump 725whp/630tq @ 21 psi. There is definitely more left on the table, but honestly the car is incredibly fast on the street. The spool of the Alpha 9s is just incredible I really don't notice too much lag even when I was FBO E85. What I am more impressed with is the A9's ability to still keep pulling to 8k. I think that maybe aided by the head being built (not ported). Rick at Defiv Power Inc did a phenomenal job dialing the car in with both idle and power. In all honestly the car runs exactly like it did on stock turbos just with a ton more power to redline. This to me is the perfect street car setup with no compromises that can run with just about anything on the road. I have a vbox sport arriving tomorrow and I can't wait to do some testing as we need to do more final tuning on the launch strategy. This car will be running only R888s. I don't want a DR or a slick. 1/4 mile goal is to trap 148-150 with mid 9s and 60-130 around 4.5 so we shall see. My current Mod List is below.

I always though the Alpha cars would be spectacular street cars. AWD lets you use the power and its reasonably reliable.
Any plans to do anything but drag race. Track days?

For road course nothing planned at the moment for this year, but I have been seeing a couple events at the Pocono Raceway for road course pop up this year that I might try out. Will probably run it on straight pump on wastegate. I had the car at NJMP once last year. |

Also the AMS Branding gives the car more value and their parts move at light speed in the resale market compared to other competitors. Last edited by RU EVO; 06-15-2016 at 03:19 PM. |

I remember when you brought your evo to the garage meet right after you had graduated rutgers, now you have an alpha 9 gtr; dreams do come true. What did you study again?

Very nice, sounds like a great setup for the street and of course the track. I can't imagine having 800+ all wheel horsepower on tap with no real traction issues -- it just goes straight without any drama.

Yep those were the good old days. I studied accounting and jumped around in the manufacturing cost accounting/financial analyst world for a little bit. Now I am Product Manager, but yeah this was my dream car and still is. Nothing out there really appeals to me. Its kind of weird actually being content with a car.

0-60s with no BOTL on the street is 2.9-3.0 on R888s. Can't really beat it and the scary part is the tune is more on the conservative side. |

Went back to the track last night and my first run was a 9.6 @138. Mph was not that high, but I did get a weird hesitation around 100mph in 3rd. The boost was increased to 30 with some additional timing up top so maybe a tq. management tweak might help. The car did trap 142 with a 1.68 60' on another run, but I lost it in 2nd a little from traction. I was very surprised to crack a 1.4 60' on R888s.
