my car is torn down for the winter and i can get a set of skunk2 pro1's pretty cheep. i know the only real way to tell if im going to benefit from the cams is on the dyno but i dont want to change the cams out after the car is back together. i currently have 97 itr cams in my car now. this is the setup.
Benson sleeved b18c1 .. 83mm cp pistons - eagle rods 3/8 bolts - p72 head - 97 spec itr cams - freera springs retainers and 1mm oversize valves - jg elelbrock mani with bbk 70mm t/b full-race twin scroll with borg s366xl. i dont want to waste money and time if they are not going to help much over the itr's. they will be degreed to tdc. thanks for any help

 

Pro 1's hands down, especially with that turbo. Some say you will spool faster as well.

 

Can you get me a set too. Its def an upgrade. You can always sell you itr cams to get money back spent on the pros. Someone will buy them.

 

Skunk2 Tuner Stg1's are also a step over ITR Cams, something to consider..........

 

be careful w/the big valves and pro1's... check the v2v clearance

 

I'm in the same boat justin, I want to run some big cams but I have +1mm valves so need to measure first.

 

the current head on the car has stock sized valves now. so i might just have to go with the current head and ditch the idea of getting the other one

 

I'd pick up the Pro1's and leave the valve size stock.

And still check V2V.

pro 1's FTW. just be careful with if you are running oversized valves. you should be ok with pro1's though as long as you don't go crazy adjusting the gears.

 

We seen 60-80whp difference @ midrange 5800-7000rpm between them...

Skunk2 Pro1 all the way...

They are inside our CFT Red Hatch... 850+whp 160+mph

CFT :->

 

The Skunk2 Pro 1's without a doubt.. They make power over ITR cams hands down.. Check out this graph, both runs at the same boost level, ITR cams vs. Sk2 Pro 1's..

+150whp is insane, and spools a couple hundred rpm sooner, guess there is your answer....lol

 

You will be fine with oversized vales, just make sure your compression isn't too high, and that you check all your clearances. Get the PRO 1's Justin.

 

Wow. That graph is nearly unbelievable. I'm speechless.

 

omg. well im getting the cams this week. sold my itr's for almost the same price im getting the pro1's for. told you it was cheep

 

pro 1's here...
395hp @ 10.9psi easy hp!!!
the bad wont pass the smog cuz you have to degreed them too much to make power
and eratic idle, my car sounds like a harley motorcycle when idleling...
overall: great camshafts

hey guys i was told by a friend that, if your boosting 15psi (gsr camshaft) making 400hp vs 12psi (pro1's) making 400hp the block gets the same abuse...
it's that true??

 

Make sure to degree them in too!

 

That plot above...

Was the same ramp rate used on both runs?

What pressures?

- Derek

 

42 psi, and either 6 or 7 second ramp rate, I dont remember off the top of my head..

 

Street car or race car and what EMS?

 

its past a street car now. lol. i may drive it here and there but idk. hondata s300

 

42psi on both tests?

What settle-in time?

Were both runs done in the same ramp and settle-in times?

Do you have a copy of the graph with the 'Show Data' option clicked on the DynaPack?

- Derek

EDIT: Sorry if this is a bit nosey of me, I'm just curious. :D

 

Did it take more duty cycle to reach the same boost after the cams were put in?

 

Keep in mind guys. When you install these cams, and if you want to see a difference like Jake did. You need to degree the cams! It will make your life easier. Make sure you have someone that knows how to degree them, help you.

 

Skunk2 Pro 1's getting it done. Good job on the tuning locash.
