2001 Automatic Coupe drove in the morning. It dyno'ed 309.7RWHP and 345.9RWTQ at 10:00AM. By 10:00PM, 12 hours later, we installed headers (no cats), and the G5X-2 only with stock LS1 Heads. After tuning was completed it was consistently putting out 394.0RWHP and 374.9RWTQ. This was a peak increase of 84.3RWHP and 29RWTQ in 12 hours with only the G5X-2 cam, headers, and tuning.

Here is the graph:

Nice gains. Does that car have a 4000rpm converter in it or something? :crazy:

 

Alright competetion ! :lol: Nice numbers.
Does this car have a stall ?

I need to ditch my cats and get my car tuned.

Does the owner post on this forum ?

Maybe we can have a shootout at Ennis Tommorrow night ?

:boxing

Forgot to add sig. :cool:

:eek: :eek: The Horsepower Fairy does exist!!! Congrats to all at LGM!! :thumbs: :steering: :steering:

 

No, I believe the car was 100% stock when it drove in. He is picking up the car in the AM, so we will tell him about this post if he is a member.

Ah, ok, I was just wondering why the dyno graph had started at 4000. I assume with the headers and everything it picked up power down low too right?

 

This customer opted for the Stainless works headers, as he did not want to spend the extra money for the LGM LT system. I believe the LGM LT's (based off prior results) would have made about the same RWHP, but had much higher torque.

pretty cool :smash:

got any solid roller grinds for nitrous use?? 6spdr...radical...

 

That is one awesome cam. What are the specs on it?

Godspeed... nice #s must I have to point out here that this dyno graph is a bit misleading. The pre-cam graph is showing the converter unlocked. The post-cam graph is with the converter locked. This will show a higher HP gain than there actually was. LG should have either showed two unlocked runs for comparison or two locked runs for comparison.

Regardless... nice final #s.

Nice HP #s, but why not much increase in torque..what should be done to bring torque up..porting?????

 

Tim,

No one is trying to be misleading, and the last thing I need is another tuner hijacking an LGM thread as if there was somthing devious going on.

We did just what we should have done, and that was to post exactly what happened, before and after.

I did the before dyno myself, and the converter was locked. I have another run that was exactly the same, and I locked the TC for that run also.
I may have locked it late, but it was locked during the run.

What I believe you are looking at is that fact that I got on, and off the gas until the converter was actually locked.

If you go to the following link, you will see the gains from another G5X-2 install on a M6 car. He dynoed 408rwhp 384 rwtq. He changed header brand, but other than that he just installed the cam and tuned it, and he got 62 rwhp from basically just the cam. We have another G5X-2 cam only M6 wtih a 66 rwhp gain from the Cam only. Before numbers 338, after numbers 404. No other changes but the cam.

The C5 graph posted by godspeed represents a before run with no cats, stock manifolds, stock muffler and a K&N FIPK intake with a 3200 stall. Plus an after run only adding a G5X-2 cam, SS works headers and a borla stinger.
We did one unlocked dyno run after the install to record on the Tech2, and the numbers were 386rwhp. So if the converter didn't lock on the before run, that would still give a 77rwhp increase rather than the 85 shown.

But in the final analysis, the locked numbers after the install are still 394+rwhp, and I believe that that is no mean feat, for a Cam only car with just headers cold air intake and a Borla.
Keep in mind that 18 months ago, 394rwhp was acceptable and common for an A4 with a Cam and head car. (and with some packages it is still common).


Sorry for the unintentional confussion.

Jawsski,
There was a spike in the torque from lifting and flooring the gas at the beginning of the run, in the before numbers, so the torque would show slightly higher than what it should be.

The headers are Stainless works headers. They are the best of the "Mid Length" headers, but still only 20" long primaries. And the car had NO "X" pipe.
If the car had our LG 32" Stainless Long Tubes and a proper "X" pipe, the torque would come up significantly. And with our header/"X" pipe the whole power curve would come up.

The next step in a car like this, (other than a header upgrade) would be to put on a set of our ported heads. Our LS1 heads flow 307 cfm @ .500 lift, and our LS6 heads flow 314 cfm . By adding a set of these we have come up with a 433rwhp, 409rwtq on a C5 with an A4 with our LS6 heads.

Again, these A4 numbers are more than 95% of the M6 cam and head cars are getting. Just 1 year ago, we had only 438rwhp/424 rwtq from our old G5 cam and head package, so 433 with an A4 is plenty potent.

thanks

LG

 

FANTASTIC NUMBERS for a cam only stock heads A4 Car. From what i have seen this CAM is a REAL WINNER & PROVES awesome power can be made with stock heads and a real performing aggresive cam like this! :cool:

KEEP UP the GREAT WORK LGM! :cheers:

Those numbers are very stout. You can't say much about an automatic that puts down 394 with stock heads. Keep up the good work.
Phillip

 

Was this cam only and STOCK springs and pushrods? I thought these had to be changed also when installing a cam....? :confused:

 

ZO6 QUIN,

I can tell you that NO WAY is that cam running on stock springs and retainers, as the stock springs would break with this bad boy cam in a NEW YORK heartbeat. The springs retainers, etc. are no doubt upgraded and come as one complete cam upgrade package. I am sure that Lou or someone else from LGM will chime in confirming this.

whats this car idle at?

im interested in this cam, but the torque numbers havent been that impressive on the cars ive seen.

 

Lou,
Have you put a package together that includes everything necessary to install this cam (lifters, springs, retainers, etc.)? I'm very interested in this setup. Can you post the cam specs for us or is it a secret?
Mike

 

How is the driveability? Low end, top end, surging?
