I finally decided to switch to a more agressive cam. I was running a reverse split 228/222 cam from Speed Inc. I made 393rwhp with that cam with full boltons, and through a SS3600 stall.
I now have the G5X3 on a 112lsa, with the same bolt ons, same SS3600 stall, but I added a Fast 90mm intake and 90mm NW tb, Fast 36# injectors, a TSP 85mm lid and a Delphi 85mm MAF.

The new numbers are 420rwhp, 378rwtq.

Not bad for a full bolt on, cam only, automatic car.

 

Nice numbers. I bet you picked up more with the intake/tb than the cam swap.

 

Nice numbers. You made the same exact numbers as my brother, I believe. His cam is similar spec'd (a lot smaller on the lift, though) and an M6 but without the FAST setup.

Looks like it's time to change your sig.

 

It seems you should have made more power then that with the swap to the g5x3. What rpms did you set your rev limiter at?? That beast peaks around 7 grand. That was the biggest reason I switched. Is the 90 combo ported ?? If not you left a good 10+ rwhp on the table. OK enough with the criticism, glad to see you went with one of LG Motorsports most popular cams. I bet you love the way she pulls from 3000 rpms !!!! I know I did. I'd recommend that cam to anyone, however I am a bit partial to version II of the g5x3. Comes on sooner and carries all the way to the rev limit.

 

I love that cam and I love how it sounds. I have consistently had good results with it as well. I'm sure you will be happy with it.

 

420 cam only through a stalled auto is awesome. Congrats

 

Nice gain, for sure.

 

yes it is-great job

 

Congrats man great result with Stalled A4 Now save some cash for good set of heads
and hello 450-460rwhp.

 

Those are some great numbers for an A4 especially, get it to the track and lay some trap speeds.

 

Wow, it must move pretty well, congrats!!!

 

Are those numbers through a locked converter?

 

that's awesome, kinda makes me mad I only made 412rwhp and 368rwtq with a G5x4 through an M6, and 10bolt with 4.10's. Stock heads as well. Sometimes I think I should have went smaller and made better torque.

 

I think the rev limiter is set at 6600 rpm's, don't really want to push my A4 to 7k, and yeah the intake has been cleaned up alittle, and will be fully ported to match whatever heads I decide on in the future.

Yes, the converter was locked when the tuned it.


Thanks everyone for the good words, can't wait to get out to the track and see what it will run.

 

based off what I remember on your graph your shift point is probably in the 6600 area and rev limiter 7K

The trans will go at some time no matter what...you will be in good shape if your trans was put together the same day as my fathers stocker was

 

With that being said, I am surprised they (LGM) didn't talk to you about version II of the g5x3. It would've been more to your liking. Peak numbers hit around 6400 and your limiter is 6600 so I could see this lil a4 holding clean 6500+ rpm shifts and making full use of the powerband.


You still got great numbers. I'd inquire about version II though. You did buy from LGM right ?

 

What supporting mods do you have ?? If that cam was installed without a FAST 90 or ported one at that, you'll never see the bigger numbers that most see. I have personally seen a c5 with everything, pully, ewp etc etc make 503 rwhp and 450 rwtq. He didn't have 4.10 gears but those don't kill dyno numbers too much. How's your exhaust flowing ?? Did you consider your stock heads are choking the hell out of that cam??

Let me be clear, LGMotorsports designed the g5x4 with one thing in mind, MAX PERFORMANCE. You won't see that unless you have all supporting mods. Better heads, exhaust, etc etc. Any missing piece makes this big lift, long duration cam less then optimized. Been affiliated with LGM for a few years now and I feel its my duty to straighten out misinformation that gets posted. Finish your combo and you too will be in the 470-500 range brother. Good luck.

 

Sorry for the hijack

 

nice numbers man...i can't wait to get some money and cam my car...

 

stock heads are killing you. you need a set of high flowing heads to match that max effort cam.

try trickflow 215 you will be impressed
