Turbo cam question
 
What would be the best cam for a daily driver twin turbo setup. The motor is stock for now and i want to make some good power without beating my valve train. I know there is a lot to look at and the question is very vague. But I would like some more info that people have firsthand experience.

:popcorn: Single turbo here, same question.

I am very happy with the LS9 cam in my car.

2SS45th 10-06-2013 09:44 PM

The LPE GT9 is the best off the shelf cam for turbos in my opinion, a custom cam is a better option though.

How is the Letal Racing Night Fury cam with turbo?

Also, who is the best for a custom turbo cam?
What cams are the winning cars running?
Who has their name on a wild turbo car kicking ass out there?

+1

Also what are the specs on the custom grinds

The specs on a custom grind cam will be (should be) tailored to YOUR COMBO (which consists of engine size, heads, desired max rpm, type of trans, rear gearing, how much boost you want to run, type of intake, compression ratio, etc etc etc).

For example, my custom centri cam was 610/575 235/260@050, 115+6LSA. My custom turbo cam is slightly bigger than that. I would say the specs but I don't know if CPR wants them out... I love the sound of a big cam and have no issues with a little bucking at low rpm. The centri cam bucked just a small bit and idled at 900rpm. I knew this and gave it a little extra gas when idling through a parking lot under power. I will do the same for the turbo cam.

Who is best is subjective. Common names are Brian Tooley, Pat Guerra, Ed Curtis, Martin at Tick performance. There are many other too.

Pyro, ask yourself how much power do you want at the wheels? The stock LS3 cam will make over 600rwhp. When it comes time to forge the engine, get a custom cam at that time. Save the money now for forging later. Don't waste money on a cam right now if you know you are changing your combo later.

A cam should be the last piece of the puzzle you figure out as it ties the build together.

I am sure the night fury cam will work. It works extremely well for centri applications. Think of this though - most cams such as the night fury, JRE, G6X3 cams are all around $400. A custom cam is also $400. It just takes a couple more days to get it shipped to you because it has to be ground. Talk to your builder and if a cam that is already established has the specs you need, go for it. Otherwise, custom.

Starting to wonder why change cam at all in a stock LS3 if you've gone TT. You can max out the motor using stock cam, so why even bother. Get a custom grind in your built motor for sure, but it may be a waste of time in a stock LS3.

2SS45th 10-06-2013 11:35 PM

Very true, 650whp is reaching the stopping point for the LS3 anyways.

Ive heard mixed reviews about the JRE blower cam being turbo friendly. Anyone have experience with that? Do most centri cams work similarly to turbo cams?

pyro449 10-07-2013 08:36 AM

Thanks for all the input. I just wanted power with pushing less boost to my motor. I know there is a lot that comes into play about the cam being tailored to the size of your turbos, how much boost, the internals, hp goals, and a lot more.

2SS45th 10-07-2013 09:31 AM

Boost will not blow your motor up, cylinder pressure (dynamic compression) will. And whether you have 600hp on 15psi or 600hp on 5psi the motor is under the same stress.

I disagree. We have to assume more boost means more heat in the charge.
I think you are better making more power with less boost. At the end of the day, a more efficient combo will make less heat.
