Default Gained 65rwhp

I bit the bullet and picked up a cam.

Dynoed 414 rwhp / 415 rwtq with my 1-7/8 inch headers and Z06 Exhaust and my tune (stock intake and filter). I ran an 11.502 with this tune.

Put in my cam and retuned it. There were no other modifications (no head work, or porting of anything).

Found myself at Fran's shop to pick up an intake manifold for a friend and he convinced me to dyno. Since I dynoed there before I figured it would be a great comparison.

479 rwhp / 436 rwtq

I think this may take me into the 10s now.

In addition, an intake (vararam) and underdrive pully and I may hit the 500rwhp mark.

Gosh, without an intake and underdrive I totally thought I was going to be hitting 470 at max



A BIG THANKS TO SPINMONSTER FOR RECOMMENDING THIS CAM!


Edit: Here is the dyno graph.

Wow! Very nice numbers, those LS3's really get woken up with a good cam. Congrats

Great numbers from just a cam, those LS3 heads breath so well that even a good mid range cam goes a long way. I'm guessing yours was a little more than a mid range cam seeing the vast improvement in HP but moderate gain in torque, I could be wrong though.

I put a big cam in my LS2 before I put on my headers and gained almost nothing but when I put the Headers on, I gained .75 in the 1/4 and another .3 when I went to Stage III heads and I'll almost guarantee your LS3 still out flows mine... I think it's time for me to Stroke and go to Milled L92 heads so I can keep up...

Again, Great Numbers!

Actually torque basically spread out. at 3000 rpms the torque was the same as before and then really picked up from there. about 3800 rpms it was above 400 ft lbs and didn't come down till about 6300 rpms. Before (I don't have my graph on me) it was around 4000 that it hit 400ft lbs, and went below around 5200, maybe 5500.

It actually isn't too aggressive of a cam either... very impressed. Spinmonster recommended it too... He's the man!

Why would you install a cam w/ the stock balancer when you're considering an underdrive pulley? Do you enjoy pulling the steering rack and radiator?

Lol! Pain in the ***.

Maybe instead of the underdrive pully I'll do the fast 102mm when it comes out.

Yeah, I'll post the before and after graphs when I get a chance. At work now, and if they see me taking pictures of dyno sheets and uploading them to the forums... they might feel the need to stop paying me hahah.

Nice numbers... I don't think the Vararam will help you on the Dyno, but it will help you at the track... The pulley would give you another 5-8 I want to see some track times (-:

I can't wait to have my cam installed

If you dont mind i would like to know the cam specs.(duration,lift,lsa)
so i could compare it to other cams that have been suggested.My car is
08 ls3 daily driver and i dont what to be aggressive either.

Thanks,
Jack

I think spin has the right to keep those specs to himself if he wants... however at the moment those specs are on another thread that I started for the hunt for this cam lol. So go fish! =)

Real nice gains Andrew, that should be more than enough for 10s for sure, especially once you get the cold air intake and underdrive pulley on there.

Sorry I sleep into the day a bit.

As always my work is all shareware.....hehe. It is nice to have the respect to ask first as Andrew did in a PM.

The cam is small by any standards and the specs are:

230 intake duration XFI lobe and 234 exhaust duration (XER lobe) with a 114+2 LSA. It should drive like stock and also makes power everywhere. I have used the single pattern 230/230 XFI for A6 cars and they made pretty much the same gains. No big splits are needed and only add more overlap. While you can hit 500rwhp with more duration, there are tradeoffs. Having measured how this cam fit in a LS2 with LS3 heads (made 478rwhp) I want to see the car that had a 234+ intake duration cam with .080" clearance for the intake valve. I guess you can play with wide LSA's to make up the difference but the power band makes it right to 6300 as this is set up.

The cam is for guys who want to hit 500rwhp with more low end TQ with ported/milled heads and there is no danger of it not fitting with some compression if you dont want to flycut much. I see cams in the 234 to 237 intake duration hitting 500rwhp but this can also work with a FI application and has little overlap in comparison. It doesnt buck and surge at low (900rpm to 1600rpm) speeds in parking lots.

Its a sane small cam thats easy to tune.

The cam is stock head friendly and this car can hit 490rwhp with just a ported intake and TB. The FAST 102 would shine on such a motor since the peak in HP from the cam would be coincident with the runner length of the new FAST. I'd bet 20rwhp at 6300rpm. When you consider what Andrew doesnt have....cold air intake, UD pulley, ported intake manifold, you have to ask why you would use a bigger cam if near 500rwhp worked with a 230 intake diration.....AND NO BIG SPLIT.

The cam was modeled on DYNOsym software and not a guess in the dark. The XFI lobe is also making some big area under the curve for the time its open. Bone stock LS2's will make 430rwhp with the exact same cam. I got 432 corrected cam only with no FAST manifold.

A local here wanted the cam when he drove a friend's car that had it. He is getting a supercharger and the cam is a decent blower cam too. The UD pulley for some isnt in the mod direction they want especially S/C guys who would be underdriving the blower.

Personally, I would use the HPI superdamper with 10% UD for a H/C car.

Spin, so this is the cam that you were testing? Do you favor it over the 228/232 .588/.595 114 LSA +0 that you raved about? What is the intake and exhaust lift for this cam? Do the pistons need to be flycut? How much more do you feel that some WCCH ported L92's would add to this cam?
