Default Dyno results for head and cam camaro, good/bad?

I recently bought a 2000 camaro z28. The list of mods is:

Futral F14 cam
LS6 intake
Ported and Polished LS6 heads
Longtubes, 3 inch y pipe with cut out

Had the car tuned and it made 377 rwhp and 362 rwtq.

Anyone have any feed back on the results?

That is low...


I made the exact same Rwhp and a tad lower on torque... At 3,500# and 2200DA I ran 7.2-7.3s@95mph however with a nitrous tune.

i thought they were way too low too. it only has 52000 miles on the car. and the elevation of wilmington according to google is 100 ft.

Go to the track and see what it runs... Mainly MPH. Will give you a good gauge of where it really stands. Dyno numbers mean nothing.

What kind of dyno? If it's a dynojet, that's pretty low. A mustang, maybe only a tad. You're going to need to spend some time/money sorting this out. Post the graph and A/F. What kind of long tubes? Was cutout open? Stock cat back? How does it drive compared to before? New plugs? Change the fuel filter? Lid? Change/clean the air filter? TB? MAF? You're not giving much to work with...

It was a dyno jet. I'll post the graph as soon as I can figurre out my scanner. THey are pace setter long tubes. I had the cut outs open and they are right after the end of the long tubes, but it is cat-less with a magnaflow cat back. After the tune it seemed to run much healthier at low rpm. I put new plugs in and changed the oil before i got it tuned. The lid is a Fast Toys Performance with no obvious signs of problem on the filter. THe air/fuel was always around 14 so i wasnt worried ab the filter.

I just have no idea what would make it so damn low. I know friends who ONLY have a cam with BETTER numbers.....

If your air fuel was anywhere close to 14 during a wide open throttle run that would be a good place to start....you want 12.4-12.8 or so. 14 is very lean for wot

Who did the porting on the heads? Was it professional or someone just going to town on them with a grinder?

I honestly have no idea who did the porting, the heads were on the car when i bought it. and do you think im having fuel delivery problems or just a bad tuner?

If your tuner did a pull and saw 14:1 air fuel at wide open throttle and wasn't at least a little concerned, it could be either.

Are you running stock injectors? For what it's worth my stock injectors were maxed out with just cam and bolt ons. Once I added heads (mild port work) I was hitting over 100% duty cycle on the injectors by 5000rpm.

Fbodies are notorious for weak fuel pumps as they age, so it could be a fuel pressure issue. You want it to hold 55-60psi at the rail for the whole pull.

Google says the F14 is a 230/234 .598/.598 on a 112 LSA

I would not expect it to peak before 6k. I can't see the air/fuel well enough on this screen to see for sure what it is.

AF ratio looks in mid 13 from the graph
What injectors and fuel pump are you running?

RaceProvenMotorsports have a great tuner and The graph looks very smooth too.

Numbers are low on dynojet 400-420rwhp will be more like it
Good luck

Man it looks like your a/f ratio never even goes below 14 to 1untill it hits 5k, then they finally got it in the right ball park. For starters I would work from there. Who did the install? I would be asking if they degreed the cam or anything. For this size of cam I would expect you to be atlest 415rwhp with your mods and mileage. Im running a smaller cam with 124k and made 428/400 with a 228/228 cam to give you an idea.

Most commonly we go to Cecil county, but Atco is only a bit further and Maple grove is within an hour or so as well


youre basically making the same power as a bolt on ls1 with STOCK ls6 heads on it. Rashon didnt say anything seemed out of the ordinary when you had it tuned?? and they only made the pull to 6k for some reason, that cam should pull a few hundred higher. Id be willing to bet its a clutch issue thats robbing you power and why they couldnt take it any higher. I had a similar setup in one of my old cars and made 415/410 with an ls1 intake.


Did you get this car from Lancaster area? i saw it on craigslist and talked to the owener a couple times.. just wasnt in my pricerange and if i remember right, he didnt have any paperwork to verify the work done to the car.

Where are you at in Wilmington? I'd be interested in taking a look at the car

Not sure why that car did make low numbers. We were wondering our selves. AFR is 12.5-8 where we put all of them. We revved it higher on a diff pull and it didnt make any more power so we didnt continue to rev it higher.

Wasnt this the car that the clutch was all messed up in if i remember correctly? If so we couldnt finish tuning it bc the clutch was shaking so bad.

I would say those are a little low for your mods.

Stock injectors and pump? I'd start there, replace both, without a doubt. If clutch is questionable, replace it too, and retune. If Fran is tuning it, you're in good hands, but it looks like you have more basics to attend to.
