Mods so far (some ordered, some already installed) are: GTP420 cam (226/226 .595/.595 112), 918 springs, hooker long tubes woth ORY, hooker aerochamber muffler, !egr, whisper lid, K&N, free mods, ftra. When I find a decent deal I'll go to an LS6 or LSX intake (my car is a 99, BTW)

I'd like to see an 11 second time slip on the motor...

I have a 3500 stall yank converter, 3.42 gears, LCAs, SFCs, ET streets, etc to help get it down the track.

So, am I realistic?

 

I can let you know by the end of the week. You got pretty much the same stuff I just put in. I get my car back from the dyno shop on thursday and can't wait to see the numbers

 

Man my car is automatic. I remember I went to the track with it...I had full exhaust and full intake done with LS6 manifold, no stall. I launched the car only from 1000 rpm and my car ran 12.7 on 4.10 gear. With stall Im pretty sure I could do 12.3 if not better. So now when u have the same set up pretty much and ull add 595 lift cam... Just make sure u provide nice air flow for You motor with that cam..and dyno tune it. Youll be easily in 11s.
I would bet $100 on that

Good luck

 

My friend has a auto with about the same set but with true duals, and a set of heads. His dyno at 368, with a 3500 stall. the stall coverters eat alot of power from what I've heard. Mine is a 6speed with almost the same setup you have but my cam is 224/228 581/589 lift on a 112 LSA and I pulled in the heat of the day in Florida 382/361 witout heads

 

Not without a custom tune of the PCM since the CAM, esp the 112 LSA has lost low end vaccum.
The PCM torque management vlaue in your PCM was set to 350 ft/lbs, as you add more performance and spike over that value the PCM is yanking out timing and with a auto trannie also unlocks T.C so you cannot add parts for performance without tuning in those mods with the PCM software.

You also need a bit larger injector such as the SVO 30's

 

I don't think 11 sec is out of the question. In fact I would be a little disappointed if it didn't hit 11's. 400 hp on the other hand is a little optomistic for an a4, especially an a4 with a 3500 rpm stall.

Good luck with all that. When did you get an ls1 car anyway? (I haven't been very active since I got rid of my 'maro)

 

Got it back in 2002 I think. it's been to the last two M events...going sloooooooow

 

Hmmm. I just haven't seen you post in the ls1 section up until recently is why I asked. So of the parts you have listed what do you currently have installed and what does it run with those parts.

 

As a rule, M6's usually take about ~12% drivetrain loss, and A4's are around ~15% loss (in "near stock" form anyways).

Now let's just say 15% loss for your buddy's A4, making 368 RWHP:

368 RWHP / .85 = 433 HP (flywheel)

That # may actually be low, considering the 3500 stall converter. With an M6, 433 HP should put ~381 HP to the rear wheels (433 HP X .88 = 381 RWHP).

Regardless of what you get at the wheels, I think it's safe to say your motor will be making well over 400 HP at the crank.

BTW, I like seeing that so many of you guys run 4.10's with your automatics! I don't feel like such a freak!!

 

The only things on the list not done are the cam and springs, and they're ordered. I haven't run it the way it sits currently. I ran it 100% stock last year, but the motor has been out since then. Just put it back in about a week ago.

When it was all stock, it ran 13.95 But it is a convertible with 2.73 gears, a4 (of course), etc. I expect it should run a mid to high 12 with some tuning as it sits. So a cam and springs will have to bring some potent numbers with it. But I think if I can couple it to a better intake and TB to move some air, and a good dyno tune, it might be there.

 

Where did your friend get his tune? I just had mine done (wrong) and they told me 290 rwhp. I told the guy you're joking right....right....?

 

A. If your staying all motor, you won't need bigger injectors like stated above unless you plan to spray a dry shot
B. You won't hit 400rwhp, but 400 flywheel will be smashed
C. It will definately run 11's on some drag radials much less et streets.. I would guestimate 11.70's-11.80s if you remove spare tire/jack and some unnecessary weight. I also don't think a bigger convertor would hurt

Good Luck,
