I could not find a clear cut answer. Is there anyway i can run a lopey cam with boost? I see alot of mixed answers in my search especially when it comes to split/reverse/single pattern cams. I will be running manifolds but i really want a lopey cam. It doesnt have to be ms4/trex lope... but i do want it to thump.

 

Yes. Talk to any custom cam guy and get exactly what you want.

 

Don't have to be a cam guru to know that the answer to your question is yes. What cam you should run is another issue altogether. What is your setup? What turbo? There's more to it than "cam for a turbo." The cam that was just specced for me will have a pretty decent lope.

The speed inc turbo cams have decent lope to them... Maybe ask them to spec you one.

 

the tu2 is nice

 

Everywhere i have read and people i talked to said lopey cams lose power on turbo. I've read ls6/ls9 or similar cam with high lsa is what you want to make good power. I have only found one guy one here that had a big cam with turbo with good power and that was NINETRES.
As far as setup the basics are c6 passenger manifold, with flipped truck on the driverside, 2.5" crossover T4 , PT7675, 4" downpipe and i will be running it on a 5.3 with 9.9:1 compression with E85. Here is where i saw NINETRES post

I guess the real question i should be asking is not can i run one. Rather am i really going to be losing power compared to the smoother cams for boost?

 

No, you wont be losing power. A turbo cam is not necessarily a smooth cam. The cam I was recently specced is a 227/235 on 113+4. That cam will have a decent amount of thump. It just depends on the combination.

That is flat out wrong.

 

A real nice cam for a mild LS turbo build will have some chop at idle if it right. Our drag car has over 270* of duration at .050, and has a nice chop at 1400rpm lol.

 

Well it sounds like my questions have been answered. When the time comes i'll probably go with tick as the threads i've seen about them sound good. They sound knowledgeable and know what they are doing with their cams. Thanks for the replies guys.

 

Holy hell!

 

Liljohn-paging Liljohn.

 

Martin at tick was AWESOME to deal with. He seemed very knowledgable, answered all my questions and just pleasant to talk to. I'm glad I went through him on my custom cam.

 

LOL Arun thats pretty funny.

Bluefire... its overlap that causes the chop for the most part... Problem is... in order to put overlap in the cam and it not be detrimental to the motor... you have to have plenty of turbine. Too much overlap coupled with semi to agressive EVO's can create alot of drive pressure.

5.3 with a 7675 is a pretty good match. Normally for a street car, id like to limit the overlap to 3-5 degrees at .050 so we werent pushing the turbine too hard. Ive done some cams where i went into the 11-12 degree at .050 range on purpose to give a guy a choppy idle... I dont like doing it but i will.... Sometimes.

Everythings a balance.... ci, turbine, EVO, Overlap at .050.... Its always best to keep everything in proportion to each other... if one gets out of whack to the rest...it causes problems.

If you want a choopy idle a cam that has 10-12 degrees of overlap at .050 will give it to you. But if it also has an agressive evo... it will overdrive the turbine and put it into choke sooner than a cam with a more proper amount. Thats what most guys are trying to say when they say a turbo cam with a choppy idle hurts power.

Its all about balance. A turbo motor is a system from the tips of the impeller to the tips of the turbine. WVERYTHING must be looked at and made certain it fits with everything else. We have to look at everything right down to the diameter and radii of the pipe and bends in the plumbing. Ive seen switching from 3 inch cold sides on a non ic blowthru setup to a 4 inch completely change a motor. Plugs were different...tuneup had to be changed... timing had to be changed...All because that bigg csa pipe slowed the air down and spread it across the carb better.

Everything affects everything.....

Balance.

 

There you go folks-the answer to your question-in full detail I may add.

Now pay the man $399!!!!!!you wouldn't get this detailed answer from Comp or Bullet.

 

My cam has 10 degrees of overlap... But I haven't put a turbo on it yet, still in the building process... I'm excited to see how it does though.

 

This may be a dumb question to those who know, but liljohn do you spec out customs cams? Are you a shop or just do it on the side? Im guessing by what your saying a smoother cam is what's best for turbo like ive been told?

 

I did, made tons of power.

 

Here's the tu2 cam.......Martin recommended it for my set up and its exactly what I wanted

 

I've got a lot of different cams to choose from now as far as the Elite Series goes that will be coming out beginning of the year. A custom cam could also be done just as easily.
