I'm thinking about putting some of the turbo cams from Crower in my otherwise stock LS. I am a little worried that they will take some of the low end torque out of my power band though.

Does anybody have experience with these cams? I've searched but never really found any concrete answer to this. I'm running 14psi and I'd like to get some more torque in the high rpms to raise the max HP.

See how my torque drops? I'd like to lessen that drop.

nice a/f .. bump for a guy that needs help...

 

yeah man bumpity bump

 

i have crower turbo stage2 cam in my gsr. i got very low torqoe when i compare to my hp. i boost 15psi on dyno= 450hp and 280torque. they said it might be my turbo cam.

 

Did you ever dyno before the installation of the cams? That'd tell you everything you need (and I need) to know.

thanks for the bumps.

 

bump... for a guy thinkin of doin cams in the next month on his turbo LS, groupbuy center deal is appealing

 

So there are all these people running boosted LS's out there and nobody has tried these cam? I feel bad for Crower. Yikes.

 

So has anybody who's using these cams dyno tuned their setup yet?

To make 450HP @ 15 psi that has got to be a big mother of a turbo, not making much boost down low, and that's why you're not making very much torque.

There was a post about this maybe a week ago, cheezefrog said he was using them and liked them, and if I remember correctly he made 500+ WHP.

 

whats your set up ???

 

that is a beautiful dyno

stock internals?

 

We need a dyno of before and after. We need to find out pro and cons, like many products you gain in some areas but sacrifice in others. Cheezefrog let's see some before and after dyno's if you have them

btw how much are they on groupbuy?

 

that is seriously the sickest dyno... the usable power curve is so flat. no peakiness at all.

That's what I'm saying! Why hasn't this been done yet?

(edit) Oh, thanks on the dyno comments. That's exactly why I'm not interested in going to a bigger turbo. This is my daily driver and I like to auto-x more than drag race. This is the IHI ball bearing turbo from the Apex'i SOHC kit btw. I've upgraded the spring in the waste gate though.

14psi on an IHI and you pulled those #s? LOL thats amazing. What kind of timing were you at at peak RPM? also stock motor right?

 

LOL, yeah, it is amazing. It's an efficient little bugger. Abradeable seal and ball bearings.

I think I'm running somewhere around 18 degrees up high. I think that's what I heard the tuner say anyway. What's really cool is that the power curve is pretty similar to the natural curve of the LS so I'm hoping that I can get more top end with out having to go to a bigger turbo. Wish me luck.

Yeah, it's a totally stock motor. It's got terrific compression (183,190,190,190) and it burns very little oil which is a miracle since I ran it with very poor engine management (7psi) for seven months before going Hondata. I just don't like poping open a virgin factory motor if I don't have to.

It's starting to look like I'm going to have to be a guinea pig. Anybody want to donate in the name of science?

 

awesome. i cant wait to dyno mine. what injectors are you on?

 

What's your set up?

I'm using Precision turbo 520 cc/min saturated with 255lph intank. Yeah, 520... weird hunh?

 

dsm 450s, equal length mani, 3" dp, t3/t4e 57 trim .63 stageIII, 2.5" ic piping 30x6x3 ic

 

who tunes your car in atl? nevermind i see, must be ed. i need to get my new set up tuned.

i too wanted to know the same results of before and after the cam install, i couldnt find any dyno's of anyone running them..i guess i didnt look hard enough :-P . I picked up a set anyways and hopefully ill have my car together sometime marginally soon for dyno results of my overall set up
