Comp Cams Stage 2 Blower Cams

[wht67]

I have Comp Cams Stage 1 Blower SPR cams (springs and phaser limiters required, 127450) with my Whipple and the drivability is awesome. I do have an automatic and 3.73 gears but no issues at all. Decent idle and nice power. I can recommend them.

I've had the comp came in my car for 2yrs with no drivability issues. Wow you've really improved ur times, practice makes perfect, huh? I guess you got the shifting problems solved. What have you done to your car to get it to 492 rwhp? I haven't been on here much in awhile.

The numbers were 517rwhp and 520rwtq, drove the car back and forth to work for a week no issue's 3 runs at the track no issues, run 4 it just let loose, and I was running 100octane in the car for about a month straight so I am pretty sure the gas was ok. The couple of things I were done to the car this year: 3.2 pulley, ford racing throttle body (love this mod), Long tube headers with CAT deletes, trunk mount ice box for the intercooler, and BMR k-member and A-arms.

Car sounds bad ass! How much hp did you pick up?

Steve damn dude sorry to hear...500rwhp on a stock block goes poof! My vote go big bore...Craig is selling his FRPP Boss50 iron big bore you could pick his up for 1k.

Already ordered block, and heads.

I have Comp Stage II Blower Grind SPR (127550) cams, phase limiters, 298 stroker at 9.1:1, Stage III heads, Whipple at 14psi, headers. Went 629 RWHP 578RWTQ. Idle vacuum is a bit low so I had to get a soft bypass controller and spent some time tuning. Driveability is not perfect but very good - even in heavy traffic. As someone mentioned, even with 3.73 gears parking lots can be a bit of a bucking bronco ride but it's manageable.

I wouldn't mess with cams.. too much trouble and there are people with 700-800 on stock cams.. just one more variable not to worry about

This is key, whipples are quite easier because of how accesable the valve is and can even be cheated from the outside.

Is a nice recommendation but running a cam that is designed with a PD in mind will absolutely deliver a nice chunk of HP and will not hurt driveability.

I was looking at NSR cams a while back that would be good for the procharger, but I dont know.. I thought without messing with springs and clips and so on that it might make things easier.. I'm sooo lost.

Havn't had a chance to get to a dyno since I installed the cams. I did pick up .2 and 2mph in the 1/4 though while I was still n/a. The sound of the cams really improved after I installed the Whipple.

ordered the 127350 cams yesterday, spoke with brenspeed for a while before pulling the trigger. They said the drivability of the 127550 is not good, and that they actually removed them from their shop car and went with the 127350's because of that, the 127550 do help the car make 30-40 more rwhp at the top end than the 127350 but I don't want to be miserable while driving the car in traffic or just around town. If I end up wanting something more, I can always upgrade to the 127550, I am sure ted would take the 127350's of my hands for a premium.

Thanks for the input everyone!

127550 sucks ass PERIOD. Just ask lito how much datalogging we did just to get it to the point we have it at now. Don't get me wrong mid-top end power is great and the car sounds bad ass while idling but is it really worth bull shit of not being able to drive around like a normal person? Always slipping clutch to pull out, trying to catch the car at a certain rpm while comning to a stop so you won't stall out (anything below 1400rpm will do the random idle/stumble/hunt for idle stall) worse when using the brakes heavy. When I get the money and time I will be eighty sixing the 127550 cams.

that is similiar to what brenspeed said, just not so blunt, that is why I went with the 127350's.

Ok, I will put my two cents in... I have 127650 cams and Tim Barth has the car running very good. He did a dyno tune and then street tuned it making small adjustments to get the street manners nice. The only issue I have with these big cams is the low vacuum at idle. I may end up putting a vacuum can in but so far my wife could drive the car, not that I would let her.

The standard Whipple bypass has too heavy of a spring for the low idle vacuum. It's a simple fix. That together with a little tuning talent and its all good. Not sure why Brenspeed isn't able to figure this out - just saying.

 

[redstangs9308gt]

Well, I haven't read or heard anything yet about people changing the bypass on the eforce have yall? I would have to take the blower off the car just to access it.

They may be aware of the fix for the whipple's but I am currently running a saleen SC.

I had the comp stage 2's in my stroked Saleen and regret not going Stage 3's. I knew another guy who had those and had zero driveability issues. My stage 2's didn't lope too much. Made good power though.

I had the Comp 127300's installed Wednesday,, The drive pretty much like the stockers ... They do have a little rumble, and did lose about 8-inches of vacuum at idle and a little less than that driving which has caused the brake pedal to be a little soft ... but they did dyno very good,

They picked up 20lbs of torque stating at 3800rpm (435) ,, hit a peak of 466 (+13 from stock) and gained 30lbs over the stock cams at 6400.

HP wise,, They 'only' gained 22 on the stock cams but I am still running the cast iron stock exhaust n' cat's and the stock Roush TVS intake and paper Motorcraft air filter. My tuner said those cams would've gained more HP with a set of headers and an open CAI,,

I'm satisfied with 507 and 465 on the stock bottom end ...

Good luck with you build ... I'm probably not too far behind ...
