THE 331 WENT ON THE DYNO TODAY!!! *VIDZ**

Yeah a stage one cam isn't very big.

5spd GT · Aug 24, 2007

A custom cam designed around a bigger exhaust is key, if replacing exhaust. As long as Mr. Curtis knows your combo, you'll be good to go You can lose power going with a 'bigger exhaust' or you can gain with a 'bigger exhaust', depends on the valve events.

What are the PS3 springs from Ed good to as far as lift is concerned? Are the PS2's .600? This is just speculation...

Too much spring?

Stage 1 cam in a 347...lol.

juiced - You running full accessories?

Max rpm is 6500, right in my cam spec's.

Is the 6,500 rpm the top of your cam's powerband (example: 3,600-6,500 on cam sheet, but you shift it 3-400 rpm higher (like most), or is 6,500 rpm your shift point?

I forgot to mention something I saw on the chart earlier

I've seen them calibrated in
SAE
STD
Standard

but

This is the first chart I've seen done with Actual tq/hp

Maybe it is the same as ... Standard

I see GRN is trying again. Dude I bet there's plenty of girls that could whoop you in a track race AND a street fight, lol.

Yeah, probably

Whats this garbage have to do with juiced's 331?? Don't try and e-thug me just because you're afraid of fast street cars. Stop responding to me, this conversation is over. If it continues, the mods WILL be notified.

5spd GT · Aug 24, 2007

He is kidding Grn...easy there, we like to play around on here sometimes, as you do.

Thanks White, so where do you actually shift at? Nice numbers from your combo by the way

Juiced - A custom cam could do you some good, but be proud of what you got man, it is a nice setup and you did it yourself...

I'm curious about Grady's keen eye and seeing the Actual HP, and wonder if that is rated different than standard, or if they are one in the same...

I think dyno differences and all the corrections really fluctuate the differences between some combos and others...

Anyone know what the PS2 and PS3 springs are rated at from Mr. Curtis?

Yeah, I mentioned the C&L in my thread. It read hotter than the black intake did.

I wouldn't look at more gear if you ever want to spray the car. I ran across the traps well over 6,000 on the 75 shot. I don't know if I have the tire for the 125 shot. Good thing my slicks are taller than my drag radials.

BTW - when are you going to a 1/4 track?

Going to hit the track in two weeks...will post up the time slip since i will probably get kicked out for brign a vert it better be a good one

The PS3 springs are rated at .630" lift, as far as accesories, I only deleted the smog pump and EGR so i still have P/S and A/C.

WhiteDevil · Aug 25, 2007

1500rpm bucking would kill me. Im a daily driver and chug around that rpm area all the time. But then again i do my own tuning and could probably fix that . Except for the fact i cant even get my car to run anymore

I don't agree at all with the anything over 1hp/cube rule being not too streetable. I'm probably in the 375-400rwhp range with my mild 347 and its perfectly streetable, unless you have a bleeding hole between your legs My sig describes it perfectly. I do think it would scare pokageek though

Its probably just too conservate of a tune being the culprit. I would however consider investing in a holley intake, custom cam and more gear down the road and really make this thing a 331

Bleeding hole there? j/k
OP there is room for improvement in the combo, I do how ever like how early the tq starts to build. Makes it fun on the street .

Grn92LX · Aug 25, 2007

Let us know when you find out the a/f and total timing.

So the Stage 2 cam is in the .560" range as far as lift. Maybe it isn't to far out and aren't 'too stiff'...

Those accessories seem fine to me Many higher dyno numbers I see over the norm, all have a few things in common: The lack of accessories

I will post up the A/F ratio and total timing as soon as Steve gets back to me with the info...i was so excited about the dyno tune that i almost left without my dyno graph and totally forgot to ask about the timing and A/F

PLUS i have to go out to best buy and buy a damn firewire cable for the video

gcomfx.com · Aug 27, 2007

Get the cable off ebay. $4 shipped vs. $40 at Best Buy.

WOW, it is like 4 bucks, i will buy it right now and as soon as i get it i will try t make this video happen LOL i bought a video camera during the christmas sales and never even opened the box until the dyno day

gcomfx.com · Aug 27, 2007

Glad I could help.

juiced_94gt · Sep 4, 2007

Ok my A/F ratio was 13.0 and my total timing was 34* Im just waiting on the firewire cable to come in the mail, He also pointed out that our cars pull timing during hot weather and thats why it feels like it pulls SO much harder on a cool night and not 100+ humid weather that we've been having. He said that after a few thousand more miles and cool weather the numbers will go up, let's hear your thoughts on this.

Grn92LX · Sep 4, 2007

Heres another dyno thread with a very close combo as you. http://forums.stangnet.com/showthread.php?t=718154

Im not sure why your numbers are so low, but maybe take it to the track since that what counts anyway. Dyno's are tools for tuning and they all don't read the same as each other. Timing looks fine. Your numbers will not skyrocket like he's making it seem with more miles.
