Well we finally found enough time between my schedule and the tuners to get the Trans Am tuned on 16.5psi. The first couple pulls were not impressing at all 777.74rwhp 756.8rwtq and the boost seemed to come in and then taper off so I decided to hold my hand under the right front where the 66mm wastegate is mounted and make a pull to see if it was holding boost and it wasn't. So we decided to put more boost on top of the gate with the AMS 1000 and see if we could make it hold and it did hold 16.5 psi and we made 927 rwhp and 834 rwtq on 93 oct + meth and it was still bleeding boost so we are going to order the co2 kit to help keep the gate closed and hopefully break 1000 rwhp.

 

Congrats! Those are solid numbers!

 

Damn that's impressive.

 

Thanks I really cant say enough about the guys at Heintz Racing they are definately top notch.

 

Surely you dont need co2 to blow the gate shut ? Cant the AMS simply use boost to blow it shut ?

Just block any signal to the bottom port ( ie the one that blows the gate open ) and apply boost pressure to the top port ( ie to blow it closed )

What pressure spring are you using in the gate ?

 

Damn I need to upgrade from my d1 fml Lol

 

Damn son! What r the details on the motor? Auto or stick? I'm going F1A and th400 right now. Those r some killer numbers.

What size blower pulley? Dyno sheet or what rpm did u spin it to?

 

The bottom port is open and and we are putting boost to the top with a 7lb spring and at the top of the run it is still leaking a good bit. jeff

 

Wow those are some nice #'s congrats. You will deff break 4 digits! Whats the specs on the motor

 

Well the specs are Ls2 block with 1/2 studs, Ls9 gaskets, ERL stud girdle, Lunati billet crank and rods, JE pistons,Mahle rings, AFR 215 heads cncnd and hand ported 10.7 to 1 cr, Del West Valves, Ls7 lifters, Comp rockers, Crane cam (634/634/254/260/114),ls2 intake, NW 92mm tb. The blower pulley is a 3.8 and we spun it to 6700. also it has a RPM level 7 4L65 and a moser 9 inch I took a pic of the last run ill try to load it thanks jeff

 

Auto or stick?

I figured it would take more boost to make some numbers like that. That's an efficient setup.

 

Hey sorry about that I just edited the last post but it is an auto from RPM and Im running a moser 9. thanks jeff

 

Man I didn't know that blower would make that much through an auto and 9". That's really impressive, I wana see some track times!

 

yeah I would like to see some track times too I took to the local 1/8 last night and ran 2 shake down passes (6.33 @114) and turned the boost up for the 3rd and didnt know it until the end of the run but I picked up something in the water box and cut the L/R slick but still managed a 6.6 with a flat tire.thanks jeff

 

I like seeing that you kept the compression ratio at 10.7:1. I'm rebuilding my shortblock and only went with a -3cc piston with valve releifs and got a lot of greif over not dropping the compression a full point. I will be running meoh/water and 93 as well and my compression is going to be ~10.3:1 depending on final measurements of how far out of the block the pistons are which should be 0.003-7".

I bet that thing is fun as hell on the street.

 

Awesome numbers! The higher compression ratio seems to be making a huge difference in power! Bob

 

Very nice. This guy with a D1 can only dream of that power level.

 

Mmmm do like. Very nice numbers man.

 

Yeah being an exsprintcar driver I just couldn't make myself lower the cr I really wanted 11:1 but settled for 10.7:1 and yeah it is a beast on the street. thanks jeff

 

WOW those are sick numbers through stalled auto with 9" Congrats.
Let's some low 9s or maybe some 8s
