I have not logged injector duty cycle yet. I should be quite safe though at our power level. I had Patrick G tune the car and he did an amazing job. I do have HPTuners and data log most passes in this car and our quicker car. I have only had to adjust the WOT shift points for the new power and TC, He told me in advance that he would leave that part of the tuning for me as that is a personal preference area.

Would this cam pass an emissions test?

I think the tune would be the determining factor for passing emissions. If you have cats and a good tune, you shouldn't have any issues, but you run that risk anytime you modify a car from it's stock set up.

No fvckin chit dumbazz!
The thing is he has a stock Z06 LS6 motor which comes with 405, he did a cam swap and got 430.... The car runs great at the track and thats what matters(to most anyway)

The ZO6 comes with and advertised 405 HP at the crankshaft bone stock. We have every bolt-on available (headers,UD pulley, Lid, FTRA, Ported TB, etc) , not to mention the custom tune. We made 430 REAR WHEEL HP. That would be significantly more than what a bone stock ZO6 would put down to the rear wheels. I think that is where the confusion is.

I hope that helps a bit.

Yep, that 405 FWHP gets cut down about 12% for a Z06 because they are decently efficient, that gets you about 356 RWHP. That 430 looks pretty good now.

Good numbers James. Sounds like the cam my Corvette needs. I was at Kurts this past Sunday having an underdrive and dyno. Kurt really is a great guy. And can he turn wrenches. Nearly lifted me off the ground trying to hold the flywheel end while he torqued the pulley bolt. And of course we know how Patrick can put that special Guerra touch on a tune!

Hope to see you and Sheila soon at the track! Any plans on going out this Friday?

Yes sir they definitely have the gift.

I am stuck working for the next few weekends, but then the racing season kicks off and we'll be tearing up the 1320 quite a bit from that point on.

We'll be looking for you out at the track.

I wonder if this same cam with a 112 or 113 LSA would make it a little choppier. I like the power numbers but I have a dumped exhaust so no use hiding the fact.

Would kinda defeat the purpose of this cam. It's a small cam designed to idle well and still perform well. If your intention is a choppier idle then might as well go with a bigger cam that makes more power.

Charles Cyrus

Great numbers!! You guys think this cam would work with 2500 converter and 3.15 gears in a '98 C5 Vette?

zstripper2k

I like the power numbers just want it too have a chop to it. Don't want a cam with huge lift and duration for longevity concerns. Maybe he can get another video with open cutout or something which would be closer to what I have to see if there is some chop in it.

good to see some actual track results. thanks

Nice for sure, I wonder if this was a happy dyno? I also wonder if the 115ls had something to do with this. I wonder if the power would have been the same with a 112 or 113.

Happy dyno? Did you see the track results? 11.29 @ 118mph at 3450lbs in normal air. I think the ET and mph back up the dyno results. 115LSA had very little to do with the results. The fact that everything works together as a properly spec'd combo is why it makes the power and grabs the low ET. If you're not happy with your current results, your combo may not be optimized for your goals.

I initially thought maybe the dyno was a little generous until we took the car to the track and it layed down 11.20s at almost 118mph. That confirmed the rwhp to be real.

The higher LSA makes for a more tame idle and better driving characteristics, but I think in most cases a lower LSA would make mor power across the power band in a NA set up provided the heads and supporting mods were appropriately matched. I'm sure more power could have been gained with a larger cam and lower ICL, but good power, idle quality and driving manners were our goal here.

Charles- I think this set up would work well with your set up. You will give up a little on the launch with the tighter converter and lower gears, but it should drive nice and traction would be easier to obtain.

ZStipper- The cam definitely has some lope to it with the cut-out open. I could also idle it down if I wanted a pronouced lope, but we don't care for that with this car. My wife has a car that covers that area in a big way.lol.

Thanks guys!

LOl. We posted on top of each other Patrick

We sure are enjoying the car man! Thanks again.

Have you raised the shiftpoints to see how much more it has on the track yet or no? Great results!

PatG works wonders with these "small" cams... Similar #'s to mine, but I need a retune. Mine is 224/228 .637 .639 110. Mine is also a dream with it's street manners! Feels almost like stock when you don't open it, but when you do it pulls very nice from about 3k and up to redline.

And to the poster who was wondering about the 115lsa; if you want a wider separation, I agree with pat where it will not change much at all.look at my #'s. They a smidge low, but this is through worked 243 heads also and at 3800 ft altitude. Pat also mentioned that my tune wasn't exactly right. However, my numbers aren't too too far off from pat's 460/410 tune he got with my same cam.

I did raise the shift points to 6350 on the 1-2 and 2-3, but only to make sure I can get past the 1/8th mile marker before shifting into 3rd gear. That is just to keep the car more consistent for 1/8th mile bracket racing. I don't know if it made much difference because I had to add weight to the car and keep the cut-out capped up to stay slower than the 11.49 safety equipment ET cut-off. I also added a 28" tall drag slick that slows it down a tad bit.
