G5 DYNO
you think you could email me the time slip, its kinda hard to guess where the peaks are. Also, where did you dyno and did they lock the converter? what heads? what were the dyno's from the MTI stuff. this could be a killer comparison between the B1 and G5 but we need more info.
Also, who told you 6500rpm shifts and a 6800 limiter. if it was LG, then im glad they got that straight....for a while they were saying 6600 limit and maybe 6200 shifts for this cam. it seemed a little low.

316.1rwt
MTI stage 2 heads,LS6 intake,ported TB,B1,and ED
Wright tuning,PI2800=370.6rhp and 378.6rwt
G5,PI3600(unlocked)everything else stayed the same,open cutout=385.4rhp and 413.5rwt
The last dyno was at LG.
R.T.=.563
60'=1.73
Mid MPH=86.66
1/8=7.84
E.T.=12.11
MPH=109.34
I talked to a few guys that have the G5 ( one without ported heads and one with) both cars were pretty close 392rwhp(without) and 400rwhp(with),both cars are running there limiter at 6800rpm and shifting at 6500rpm. Both are running
low 12's. I would think with this cam you could
raise the limiter a bit higher. Like I said, my
dyno runs all the way to 7500rpm.

<strong>These are my results with the G5 and without tuning 385rhp and 413rwt.My question is, where do I set my shift points? They said they would put my shift points at 6500rpm and set the limiter at 6800rpm. I'm confused <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> On my dyno, my peak power is between 6400rpm to 7000rpm. A/F is set at 12.5, Need advise on tuning the shift points and limiter. Ran without the tuning and got a 12.19,need to get the tuning right, then we'll see. I changed from the B1 and PI2800 to the G5 and PI3600. Should I set my limiter at 7300rpm and my shift points at 6900rpm or that to high. Please advize!!!</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">I have to wonder at this point if your MACs and ORP are limiting you. I wonder if you put some LT headers and ORP on if you wouldn't get alot more HP with the Heads and G5 .. I thought I heard LG was hoping that with S2 heads, G5cam and LT headers w/ programing you should be around 430rwhp ..
Anyway .. Im getting ready to do this (stock heads). I'm hoping for around 400rwhp (with pulleys)..

also, mac's arent a limiting factor. you MAY be out 3-5hp and 5-10tq but thats minimal at this level. longtubes help more-so in the mid range on the street.

I made 413rwtq a few years ago locked with heads and cam.
I just made 502rwtq unlocked. The spike in my case is about 600rwtq.
Reason not to get too greedy is that the motor is not built to see those kinds of rpms on a regular basis.
I would say 6600-6700 is the max I would do if you want to that motor to live a few years.
My current motor has seen 7200 rpms on the dyno and it's built to the hilt.
One person posted 12.xx with a 109 mph... was that after the G5 cam? If so, that doesn't make much sense as the mph doesn't really seem to represent those high dyno numbers.
Does anyone else have any ET's from this cam? I would have thought with the numbers it was putting out that we would be seeing a lot of low-mid 11's. What's the deal? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
<strong>Maybe I'm rehashing something that has been spoken about before... but all of these high dyno numbers with the G5 cam, and I am seeing ET's posted in the low 12 range? Is that with stage 2 heads and the G5 cam? Or is that before the work was done?

I would have to guess that the MPH was a before the work was done. A guy did just the G5 cam and picked up 30rwhp and 20rwtq .. I would think you would pick up about 2-3 mph right there .. I currently run about 107.7 .. that would put me close to 111mph with just the cam ...
I haven't seen any other track numbers posted for this cam.
Anyone else?

The G5 cam and heads put out killer numbers but 113 to 117 trap numbers are not too impressive for the numbers I've seen posted.
Hell my first time out with my 440RWHP'd CARTE S2X setup put down 120 to 121 MPH times in a 3480lb car.

the ONLY track times ive seen are RAT's. low 12's at 115 or so. but its NOT a track car. 3700lb and F1's. 12's aint that bad. LG is just not a 1/4 mile company and until it gets a strong big stall car as a customer...their cams just wont run the number at the track.

Not the day I was there.Also I have 6 runs on my car and Dave has about 4 run too.Thats a total of 10 runs since the cars been done.Not exactly giving me a chance huh,Terry.
Where did u get 117 from?
Another one of your ASSUMED FACTS that u love to enlighten us with n here.FWIW Terry my car went 119+ with me driving at a RW of 3616lbs w/o a LU switch.
U on the other hand went 119 at 3430lbs.I'd be worried about your setup not mine <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

If I added 80 - 90 rwhp to get to 400rwhp you don't think that 115 trap speeds would be a good gain? That would be a good 8 mph gain in the 1/4. I'd take it ...
I can't say that I am the best driver at the track either ... my times show that <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> (13.2 @107.7). I don't know what I am dynoing right now .. 306 was stock and I have only added a lid .. once I get some changes in there, I'll keep you all posted on what it can run.

<strong>Crowley u make alot of sense.I shouldve looked at it like that.Every car is different and reacts differently too.

Now ... that is if I can get to the track a few time and learn how to drive LOL ....
Anyway .. Eventually maybe I'll build the rearend and get a better clutch in there so that I can break the 11's with some good tires on the car!

Is the G5 just a peaky cam all together? Or does it peak too high, and people aren't shifting high enough?
This cam interests me only because it is the first cam that I have seen have such difference in dyno performance vs track performance. I know there are dyno queen cams out there, but even those have decent mph at least. I am just trying to understand where the power is going when a car dynos so well, then doesn't really run stellar at the track... not just higher ET but lower mph as well. Does it peak at a point where a stock bottom end couldn't handle shifting that high for many passes? And we just aren't seeing what the cam is capable of because no one wants to spin that high? Just curious.
