No, you require a custom camshaft to harness this instant. We're considering wild grinds were the customer will require to change just the intake cam gear from stock to adj. This would allow us to come up with wilder grinds in both regrind and billet form.

CbYellowSS

so you mean for that much horsepower he would need a custom camshaft???

because i was going for this much also and i would like to know everything i need for internals

and a core is your stock part that you send back correct???

but what is a blank?

JBP

You have to take several things into consideration. (ie: how is the power going to be made, via how much boost, turbo, supercharger, etc..) Also, you will lose a significant amount of bottom end torque with a custom radical grind, as we would project the powerband up quite a bit to gain more power. This is all done through the camshaft and cylinder head. We've done several LD9s that hit up in around the 500HP mark. For these, the heads were opened up and flowed, as well as the camshaft profile made to match the head. It's mostly paperwork. You also have to realize that custom camshafts would require manditory tuning. But these "off-the shelf" triflows should be more than adequate for those who want to have driveability and be able to make power.

Blanks are "blank" camshafts that do not have a profile (yet) ground into them.

Okay so How close will I come to 400HP with m62 SC with a 2.6 pulley, cam grind, 10.5:1 pistons, 60lbs injectors, HP tuned, 3" exhaust and manifold, intake. would a lighter flywheel and rods benefit.

JBP

400CHP or 400WHP? big difference.... Basically, if we're talking at the crank. You're doubling the output of the engine with three power mods, (compression, cams and pulley), natural mods, (intake, 3" exhaust, "manifold"), and free-up mod, (Flywheel) and lastly, safety mod & slight free up, (Connecting rods and tuning.)

I'd wager, and I'll never, (ever) post a definate HP gain, that you should be a tad over 310-350CHP. Again, only way to be sure... install it all and head to the dyno.

CbYellowSS

so to make the 400-500 horsepower we would need the custom cams???

so the customs would produce more horsepower than the tri-flow???

and wouldnt u need to tune with the tri-flow cams anyways???

JBP

Yes, to make 500HP with a custom Triflow, youre at the point where you need a very aggressive profile to squeeze more than what the Stage 2 Triflow can deliver.

With the Stage 2 Triflows, you don't need to tune, but it's a good thing anyway.

BlackSS/SC

How much HP are these cams good up to? With these cams and a set of valve springs would it be safe to rev to 7500rpm or around there? So it make more power across the whole powerband? Do you have that older dyno sheet of the cams before and after on the stock 2.0l that you could post or email me?

JBP

the answer to your HP question is one post above yours. Yes, with these cams and valve springs, you'll be safe at 7500RPM. Yes, power gains are across the powerband, the dyno sheet i'll dig up and post publically.

JCswoosher2

what about cam gears? how necessary are they?

JBP

Not necessary. Springs are recommended though.

Edubs

Now I think you addressed this, but could you rehash?

If we have the GM Stage 2 will there be issues with the stock valvetrain revving up to 7000RPM with these cams? Basically, would it be necessary to upgrade at that point, or just advised?

Why do I ask? Eventually I want to build a bare block up with all the goodies that are out for the LSJ to be bulletproof. That is when I would plan on using a ported head with upgraded valvetrain components. Until I can build that engine; though, which is years down the road from being complete, cams seem to be a nice touch to a daily driven LSJ.

My setup would be GMS2, CAI, Full-Exhaust + Cams daily driven. Yeah or Nah?

EDIT: Forgot to mention that I plan to Dyno-tune this setup when complete.

JBP

You're right on the line of decision. You can, at this time, get away with the camshafts at the redline you've indicated. But I strongly recommend at least a valve spring swap. We sell LSJ valve springs that can take the stock retainers/locks.

NoRemorse

Those numbers have been attained with almost those exact mods. I'm talkin' whp. The LSJ I have in mind had a ported head and Ti valvetrain as well (revving up to 8300rpm I think) The car is out of commission at the moment, but is being rebuilt even more this time.

Sorority Demon

So if revving to 7k on this setup is borderline, then can I assume it would be safe to simply have the cams, w/o tuning, hit the street, and have them produce gains if I plan on not going higher than the as shown 6500 rpm redline?

Edubs

That's the word on the street...

JBP

Thats correct. You can install the camshafts without any further modifcations to the valvetrain, pending you keep the 6500RPM (stock) redline.

Edubs

How dangerous do you really think it is to run the stock springs on these cams at 7k? Cause if it's that bad then we need to talk...

JBP

On our spring dyno, @7K with the stock cams and springs isn't a problem. When you introduce our camshaft profile, you're still not quite in valve floating territory, however, you are introducing a resonance that could literally break the spring-wire. Why risk it? Just upgrade your valve springs if you're higher than stock redline w/cams.

Edubs

Okay, then when this GB starts to come to fruition, I'm going to need to talk to you about Springs, possibly locks, retainers, seats, etc...

zinner

The cams still giving the out of sync CEL?

Also what do you recommend to go with the CAMS? If I spend some money I would like to be able to increase my redline.

JBP

No, that CELs long-gone.

Like I mentioned, the JBP springs are more than enough for people who are staying under 7800RPM. The nice thing about these springs is that you don't have to spend a fortune on locks, retainers. They are interchangable and fine for this RPM level.

Edubs

Pardon the stupid question...

How will these cams effect exhaust flow? Seeing as I plan on having a custom exhaust made, should these cams effect my decision as to what size exhaust I use?

My goal is to have a 2.79" pulley dyno tuned with 60 lbs'ers, these cams, my custom 3" CAI and custom full exhaust. Should be enough with the right suspension mods to get me into 12's...

takes5tries

so what is the max hp that these cams can take????

JBP

There will be an increase in boost. You will peg the stock boost ctrl solenoid with these cams, so there will be an increase in overall flow through the engine. 3.0" inch would be ideal as well as to support future mods.
There is no MAX HP rating for these cams. They can take any horse power range. However, when you want to make a large gain, a custom grind is recommended.
