I was planning on a ls6 cam for my 01 lm7 5.3 turbo... now iam thinking I want some more lump to it.. is there a good off the shelf cam that is good with boost and has a little lump to it??

i picked up 9mph cam only going from stock cam to a isky triple 12 from JFR(stock48)

on a 76mm powered stock 4.8 car.

you guys make this triple 12 cam sound like its the end of all cams, anytime someone asks for a turbo cam the triple 12 pops up. Does anyone think that there is any science behind a 212, 212 lsa 112 camshaft? It might have on ONE combo, but not on 500 different combinations, different motors, turbos, fuel, boost, heads, exhaust yada yada.

I could come up with some random cam specs blindfolded and it will make power over any stock cam.

It works very well on setups at 6 liters and below. Guys with 400 inch motors are obviously going to benefit from a bigger cam. There are cams out there that make more power. It just does a great job of balancing idle, street manners, power, and spool.

As a general rule "lumpy" cams and basic street turbo setups don't usually go together. I'd Just use the LS6 cam. The time in the sig below was done on a JY LM7 with the 90$ GM zr1 cam. I think I could have gone just as fast with an LS6 cam though...if not faster.

That being said I'm using one of Stock48's cams next season as well. I went with the 215/215/112 just to be different.

No one said the triple 12 was the end all of cams. It's just an option for someone that wants reliable combo that's snappy out of boost... There are many cams out there to choose from.

You seem to be a wealth of knowledge... I was wondering how quick you have been with a daily driven factory block/oem head turbo car or truck?

Yes. There is science behind anything that works well.

I was going to run a LS9 til I spoke w/ Martin from Tick Perm. Im sure he can lead you in the right direction.

I do know a few things, I don't drag race and I don't understand what does the factory block have anything to do with your cam selection... I do however run 21.5psi of boost from a Whipple 4.0 on 93 octane through a 427 with no meth and make 1000+rwhp AND daily drive, you tell me how. Static compression ratio is 9.0:1

ayousef

why don't you enlighten us Jake? I hope its none of the nonsense you told Ahmad though, you were literally explaining what overlap meant which I think I already know. Overlap is just ONE factor when picking a cam. Unless you're running into extreme backpressure issues with a turbo not properly sized for the combo, having more overlap in a cam makes more power in any FI set-up, turbo, blower or NA.

The reason you think it works is because you never used a cam that has been specifically ground for YOUR application.

I see people with 4.8 engines use this cam, then 6.0 and so on. Different head flow rates, different intakes, different displacement, static compression ratio, turbo size both compressor and turbine/housing, converter stall, redline, fuel and more. Believing that there is ONE cam that works the best for any turbo build is plain BS.

Like I said initially any aftermarket cam will make more power compared to a stock cam, does that make it good? And unless you've been testing cams or have quantitative scientific evidence to your claims on the all-mighty triple 12, I call BS.

Nobody, and I mean nobody... on this site ever claimed that the triple 12 was the be all, end all of cams....as Jarrett already admitted. It works in plenty of applications to varying degrees...how optimal it is depends on those things you mentioned. But I do believe the quantitative evidence you are requesting is already readily available in the number of people who are out there kicking *** with that camshaft...you can't argue with the overwhelming results. You just can't.

I can explain the quantitative stuff, but first, you have to answer this: do you care what I say? I'm done wasting my time with people who like to play rhetorical games just for the sport of arguing.

I run a used lunati stealth cam. I tried to find something close to the GT2-3 that skinnies used at the time. It's 216/221 .585 on a 114LSA. I would like for it to peak a little higher than 6000rpm but it is great out of boost and allows me to spool my T6 S475 very quickly.

5.66@127mph in the 1/8th and 8.76@156 in the 1/4.

Should have just stopped right there.

I always found the custom-cam thing interesting. Cam co's want to know all the above items. But really, is somebody adjusting cam profiles for static compression, AR size, intakes? I think that is BS more than anything. I believe an engine is way too dynamic to make assumptions. Unless there is some high-zoot computer system out there that can utilize all that info, and who's to say THAT cam was right? Maybe there's another cam out there that would be even more "right" than the right cam.

In the end, I always err to the side of experience with just about anything including cams.

That's really what it boils down to. A customer would need to answer a few dozen questions regarding their requirements for the camshaft. You then have to model the cam using a software package that is diverse enough to give you some good results about how it behaves in any number of conditions. Then you'd have to get a prototype to test the requirements to ensure its up to spec. But this takes far too much time and money...so it doesn't happen. And that's where error is introduced due to opinion.

If I had a comprehensive list of requirements for a camshaft, I daresay my triple 12 would meet all of them. Drives like its stock, fantastic low end, and makes 1000hp at the wheels when I want it to. Its not for everyone...but its a safe bet that has been proven on a number of configurations.

I will be using this cam for my 4.8 stock 799 ported heads, ls6 intake, with a s400x 1.10/ar. I should be able to chime in on idle and street manners in a couple weeks.
