Performance Camshaft Questions Again

[NormalAspirated]

Sorry guys ... Camshaft questions again. I had did a search and still have doubts. Any answers is greatly appreciated.

My 03LE'Busa is having a stock motor, I am looking into to get a set of performance camshaft for the start. For my application, I would to have cams that provide me with long duration and high torque priorities, not HP numbers.
From my search I had concluded Yoshi stage01 with correct degreeing would able to do that.
Now is there any other options or something better I can look into ?

I heard BD intake cam with stock intake on the exhaust works pretty well too. Is this true ?
Or having one Megacycle cam intake with stock intake combo ? This will gives the best of both world between torque and some substantial among of HP ?

I am pretty much a end user, please give me some inputs ... I am lost !

Froma what I hear bang for the buck is to just go with the 2 stock intake cames on a stock motor, I will have some numbers here in the next month or so as I am getting ready to put some in my bike and get it retuned.

I went with 385 mega cams degreed At 104 /106 very pleased ask Dennis

I want a broad power band if possible. Something better than the 02intakes.
Yes to the Megacycle, one of my buddy is using that, he is contented. 

Always wanting to see a dyno graph of different camshaft effects and I know is hard. I need more input to analyze my final conclusion.
I know there are a few engine builders here, please help. Looking forward to your reply.
Thanks to Rinaudo and gixxer2k1000 for sharing.

Buy my 378 Web intake.  Will get you 180rwhp and 104rwtq witha pipe and PC if you put your current intake on the exhaust side and get an adjustale sprocket for it...

[NormalAspirated]

No thanks ! I would prefer Megacycle if there is one. 

Rinaudo have you done your run ? How is the graph like ? Keen to see.

High torque achieved through long duration camshafts is almost internally inconsistent; it would be better to think in terms of just the opposite.........shorter duration camshafts with increased lift. You are on the right track, though, as the Stage I Yosh cams and the Stage I Megacycle camshafts are proven combinations that work well with stock engines with aftermarket headers/pipes and PC's. I think you would be happy with either set...........but the Megacycles will give you a tad more peak with no discernable loss in the middle. If you want to patch something together, you could go with a .378 Web with a stock intake on the exhaust or a pair of intakes.

Missing a heck of a deal...

[Rinaudo]

have not dynoed after cams but before cams I was pulling 167Hp so I figure I will maybe make 10 more or 12 I know It is very strong ,The higher you degree the cams the later the peak hp will come on, the 167 was with motorhead's 6.2 map my bike is 2001 so I use a pc2.

I made 168/101 and went to 2 intake cams (one was the Web 378) with NO PC and made 178/104....With a Yosh pipe...

[NormalAspirated]

Care to share some cams infos. Thanks !

I made 168hp with a small box mod, PCII and a yosh rs/3 race pipe. good pipe, I think as good as the brock, but with a little more low end power. I'll bet your web/ intake cam combo would have made a easy mid 180 number with proper tuning. where were the cams set 105/107 maybe?

I was thinking a set of megacycle 385/385 at 105/107 would give you decent lower und pull with a good mid and upper speed rush. Plus these cams also work good with a 1397cc kit as well if you think you may upgrade in the future. I would not consider these cams to be a race setup just a strong street motor, and they work well with stock springs

Do Megacycle's need to be shimmed like Web's?

[Rinaudo]

 

[Rinaudo]

No

[superbikee]

Quasar, I agree with you 100%.

[NormalAspirated]

The 100% correct answer to your question lies in the clearances YOU measure after installing the cams of your choice. That is the ONLY way you'll know if reshimming is required with ANY cam.
My .378"/.330" Web Cams install required that I purchase a single shim for one of the intake valve clearances. The shim only missed spec by a mere .001". All the rest (intake & exhaust) were easily within spec but I wanted them as close to dead center nominal as possible so I swapped two other shims to obtain anal perfection. (Anal or not, it does wonders for "Peace of mind" down the road. )
IMHO, I think Web Cams have been given a bad rap for far too long. I now have over 24,000 miles on my Webs and my engine's running fantastic. I've never had any problems whatsoever with Web camshafts in the past but then, I take my time and take every precaution when building an engine. I assume nothing and measure EVERYTHING.

I've used more than A few sets of Web's. They grind the crap out of the base circle for some and do not for others. I had a set of custom valves made for one bike the became useless because of the overground base circle. To be fair the keeper grooves were a little high BUT the bases were ground alot. Anyway I've have had other problems with Web but the set in my FJ are great. As far as I'm concerned Yoshimura are the only cams that follow OEM base specs.

Have you upgraded yet and any numbers would be nice  .
