So before i hit the dyno next week for a tune i wanted to hear some final input i have read a few different threads on theses cams on turbo cars and people have different opinions on them. My question is should i stick with the pro 2 cams or put my Gsr cams in? I got the pro 2s with my car. But I have read that theses cams will just choke up on my setup and i will make better power with a lot less boost with Gsr cams than I would with pro 2s. Here is my setup any information is very much appreciated!
81.5mm lsv stock sleeves
Eagle rods, cp pistons 9:1 comp
Acl bearings
Gsr head port and polished
70mm tb
Super tech valves, springs and retainers
Turbo is 60 trim turbonetics with billet wheel

Thank you!

Even pro 1´s are to big. To much overlap combined with to much backpressure. It creates heat and bad efficiency. On a drag car with hughe turbo for 1000 1200+ hp it MIGHT work. Not with that "small" turbo.

Definitely put the GSR cams back in... it isn't negotiable LOL!

i had a similar setup and my pro1's did not work. stock gsr cams were worlds better. i make just under 500whp on stock gsr cams.

So went to take the pro 2s out of my car and put the Gsr back in and The pro 2s chewed up three vtec rockers. So new vtec rockers and Gsr cams in and getting dynoed Sunday. Hopefully I don't crack a sleeve. Lol

Wait, what LMAs were you running? If stock that is why and the LMAs should definitely be changed now.

You guys are way off, Skunk2 Pro 1's will blow away GSR cams. I was running Type R cams in my setup with a t3t61 and made 710whp at 28 psi. I swapped over to the Pro 1's using the skunk 2 lmas and dynoed 725whp at 25 psi.

So I made 15 more whp at 3 pounds of boost less. Would have been a bigger gain but my turbo was done and maxed out.

Now as far as Pro 2's, I wouldn't know since most turbo cars weren't running pro 2's.

I have seen some cars pick up 30 to 40whp using pro 1's over using GSR and Type R cams.

on my setup the pro1's were not working at all. for someone making 700 whp im sure they are fine. as i believe was mentioned before, they do well on setups where the turbo flows 60+ lbs min. i only make 480 whp and they were not liking my setup at all. switched back to oem GSR cams and everything was great. when i rebuild and go with higher compression and a bigger turbo im sure the pro1's will be great. however on my current setup they were not. my tuner also told me he had issues with another car making around 500whp that had pro1's and they were a pain to tune and just didnt work all that well. Again, a change was made back to OEM GSR cams and then everything went smoothly

Hardcore 97 did you by any chance get tuned by JT Auto or Revline in KC area? If you don't mind me asking whats your compression, bore, turbo size, and what fuel did you run hardcore 97.

I ran these cams when I was making 500whp, plus I am not high compression. I am running 9:1 compression with my setup, my buddy was making a little over 500whp on a 60-1 and swapped in pro 1's and jumped up 40whp.

It is most likely a tuner issue, but I guess I can't say they work for everyone but everyone I know who ran these cams over stock made big power.

Then again we have Locash tuning our cars so that could be the difference.

Definitely a tuning issue. Cam tuning is essential.

I am very confused why you guys keep talking about Pro 1+ cams. Yes, they work well depending on cam settings and turbo setup / size. Again, it all depends on what characteristics are trying to be achieved from the engine. This thread was started about Pro 2+ cams and they are very different than Pro 1+ cams. In this situation (Pro 2+ cams) he needs to go with the GSR cams hands down. There isn't even a reason to debate this as it's ill logic to use the Pro 2+ cams.

Some people have mixed the Pro 1 & 2 cams on high WHP builds with great results. Most people aren't interested in buying two sets of cams when there are other options that would be more specific for cheaper (custom cams). Also, to reiterate, it is pointless to focus solely on WHP gain unless that is what you are going for. I would like to know how much midrange you lost by switching cams. It all boils down to what you are trying to achieve.
