good deal. who's doing the work for you?

jz06man

Tom at Speed inc here in Chicago will do the work. Tom has done most of my mod's and I'm very pleased with the results...

vinci says good things about them as well.

I'm _SO_ glad someone else is going with an ***-Kicker.

I think you'll love this cam. It pulls hard from 2K up - with LOTS of low end power over stock. I don't like to rev over 6K, so I can't tell you about what it's like up there. From the dyno on their site, it looks like it'll pull well to 6,500.

I'm still using mine on stock manifolds and converter.

Here's mine at idle.

The thing sounds nice and healthy throughout the 2-6K 'powerband'. Here's a half throttle roll-on to 60mph. Don't laugh, f-body guys - imagine towing 2,000+lbs behind your cars with 80lb wheels at each corner. The video is bad, just use it for the audio.

Marc W- I'm looking forward to the results.. I pick up the Z on Friday. Will let everyone know after this weekend.

Your idle video sounds pretty good for stock.

Mrr23 & Marx W,
I pickup my car yesterday for Speed inc.. Well what i change. The car only pickup 30 RWhp and 25 rdtq at peak. I would haven thought/wanted 40, but she feels real strong!!!

It's lifted torque 25-35 ft pound threw the entire power range and lifted power 15-40 rwhp over the power range. You can feel a slight increase in torque at 2K and then from there everything has changed... It was wet here yesterday, so i could not get her to 5.5 or 6K, but today might be a another story....

Idle is abit more agressive, but not much, will little change in idle quality. There is a very,very,very slight lobe to it, once hot and idleing for a while-But not an issue at this time.

Will have more to report later.

Thanks for all the feedback to date...

marc_w

Awesome - glad you seem to like it... It's nice hearing some real world numbers off of it. I love that little 2K bump in torque - I've got my part throttle shifts to sweep across 2K through all of the gears at lighter 'cruising up to speed' throttle.

About all I can claim is that with the few mods I have (some add weight, like dual exhaust, underseat tool-box, and sway bars), that the cam helped push my truck at full street weight and 20 gallons of gas to 14.5 at 92.

I've got to get it weighed, but I wouldn't be surprised if it's north of 5500lbs.

good deal. seems you're liking it so far. when you can, post the graph if possible. did you do the rockers also?

i highly do not recomend the Z06 cam i took mine out a few weeks later

jz06man

Well here is someone late to the party..


I did do the rockers...
I don't think they did anything except increase a very slight lope at idle..


Marc W. 14.5 sec 1/4 mile for a 5500 pound truck is impressive..
I ran the car today to 6K.. it felt very strong. At 4200-4400k rpm it seems to pickup faster onword to 6K..

Car can now rotate the tail on deman in 1,2,3 gears and a slight pull shifting into 4th..

Overall very nice, but I really thought i'd get a bit more torque.. 405rwtq is great, but all indication were- i could see at least 420-425tq...

On another note, what kind of a/f ratio's are you running. mine is a safe-steady 13.-13.2 from 3.3k to readline... If i lean things out a bit, might this increase tq/hp???

PREDATOR-Z

I would say this is just right. Too lean and you'll run into KR that will make your truck inconsistant depending on the weather.

he's got a Z06 not a truck. but for the most part, people seem to agree on the 13.0 as being the right spot.

jz06man

ok, si it seems a/f ratios are ok.. I thought so... So the other factor to look into would be the advance timing- Where it's at and can it go a bit higher. Is this correct..

mrr23

iTrader: (3)

with the a/f ratio where it's at, it would seem all is where it should be. if can take more timing, then you can add more fuel as well. normally what i do is add all the timing i can. then add fuel. then i'll go back and do timing. do this until i get the deisred results i can.

Don't focus on peak horsepower/torque gains. Appreciate the average power gained throughout the usable rpm range. Sounds like a great street cam. Congrats! Time to take it to the track, have some fun, and get pleasantly surprised with some great times!

jz06man

Your right, and i am focusing on power under the curve, but these numbers seem a bit low for head, cam and rockers... Don't get me wrong, the car is much stronger than before... I've timed the car at 0-60 4.5, and 1/4 at 12.5..

I know the numbers could have improved with my launch tech.

Now I'm sure it should run very low 12.??... with Drag radial's I'm in 11.?? teritory..



Marc W, 14.5 with a 5500 pound truch is very fast.. Congrates..

Mrr, I'll give Joe V. a call monday for follow-up....

p.s. first time I've been able to smoke the tires with my wife on board... I so mean lot's of smoke!!!!!!.

marc_w

Thanks for the compliment.

For what it's worth, I'm running 26* above 2200... 28* above 4000... 29* at 4500 and 30* above 5500rpm...
