G5 DYNO

G5 DYNO 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!!!

Re: G5 DYNO Just wondering, what did you dyno and run before the cam? I am just about to cam mine and was just wondering how much you gained, btw that torque is awsome.

Re: G5 DYNO wow, might be time for some research. 7300 is just a little (sarcasm) high for a stock motor.
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.

Re: G5 DYNO My car w/ SLP lid and MAF, S2 TB The G5 cam, computer tuning and stock headers and cats dynoed 365hp/355tq. I installed my FLPs this past weekend and will be redynoing this coming Sat. Hoping to break 400. My shift point are set at 6500 too.

Re: G5 DYNO Before all the major work, exhaust,headers,lid,hypertech,3.73 gears=305.3rhp
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.

Re: G5 DYNO I think 6,500 shift points are still too low for this cam. Just do a search for Tony's dyno graph and see where, and for how long, this cam builds power. dyno graph Hell, I'm shifting at 6600 with my Comp XE-R 224 cam, and the G5 is bigger than mine! Also, the only way that you'll be able to compare dyno #'s is with a locked converter. The Vig 3600 is going to sap more power on the dyno compared to the Vig 2800. This is also why you showed 413 RWTQ; it's a converter flash. Peak HP looks to be coming in right at 6,600 RPM on Tony's graph, and you want to shift a few hundred RPM past peak for optimal ET's. If it was me, I'd be shifting at 6,800 for the best ET. 6,500 RPM is too low if you look at the graph. The MAX RPM I would take a stock bottom-end to is 7,000 RPM, and even then I'd be leary with longevity. Judson Massengill shifted at around 7,500 quite a few times with a stock bottom-end back in the day, but the car certainly wasn't a daily driver, and an engine was built soon after that. I'd set the shift points at 6,800 and limiter at 7,100 and have some fun. The Vig 3600 should work really well with that cam.

Re: G5 DYNO re-dyno. this time lock the converter. your dyno will show a much higher rpm when the converter is unlocked (thats why you see 7500rpm). not to mention lower hp numbers and higher tq. you prolly put out 41x and 39x. now, as far as shifts, Tony's dyno was unlocked too, so we are all pretty SOL when it comes to seeing peak rpm on the cam. i say just shift at 6600 and redline at 6800. its safer and you cant be giving up THAT much power.
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.

Re: G5 DYNO Well, the tq could be that high it's hard to say.
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.

Re: G5 DYNO 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?
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" />

Re: G5 DYNO Erin makes a great point.
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.

Re: G5 DYNO lets not bring in track times J$. No offense but that $cartek$ rig hasnt impressed me yet having $440rw$. Chris Marsh went 10.9 with 430rw and 3450lb.
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.

Re: G5 DYNO Minus 1000?What r u talking about Terry.
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" />

Re: G5 DYNO Bear- your numbers are the best I have seen so far for this cam, get rid of the rear and tranny problems and I think you will definately be the fastest G5 cammed car, at least that I have seen here. Your car is very heavy also, right?
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.
