what kind of power gains or losses is there from installing web,broch cams vs. the stock intake cams on the exhaust side other than the price? :roll:
-
I think about 4-6 more hp with aftermarket cams over the double intake setup...
-
what kind of power gains can I expect out of just switching the exhaust cams to intake cams? I am thinking of going to a 1397 with 13:1 pistons, is there any down side to the 1397?

Probably get about 4hp if you get them degreed good... Just a guess..

from my understanding 196-200 hp is the norm for a 1397 13:1 with intakes on the exhaust side with no porting to the head is that true?? I know HAVE 169.9 HP WITH THE BOLT ON'S AND MAPED . IS THE 1397 A DRAMATIC SEAT OF THE PANTS GAIN?

I hear the above 8K pull is sick!!!

You're not going to achieve 196 ~ 200 HP with only two stock intake cams and 1397cc pistons. It'll take better than stock cams for intake and exhaust to achieve that kind of HP.
-
what kind of power can I look to get? and what cams should I use? I thought going to a bigger bore and raising the compression that much would do it.
-
Yosh work good and Mega Cycles...
-
do they effect driveability at all ? I don't want to buzz the shit out of it to get power. I drive mine on the street alot and double with my wife so that is an issue. I see brock sells his custome cam or is that a webb cam?
-
Dude -- build the beast or don't....
-
I am going to do it. I'm just doing it a little at a time so I have all the pieces to do it over the winter.I found things go alot smoother if I get alot of other peoples opinions and hear their problems. I like the turbo idea to be able to just turn up the power when you want is nice but the problems that go with it don't seem to be worth it.

I have a set of Web cams in my bike and I love them. I don't see how your HP was so hi with just slip ons, but it could just be a happy dyno. When I brought my bike in to get them installed I had a BDE full system, small box mod, k&n filter, Pair removed, PC3r and I made 164.94hp/98.51 torque this was with the brock hindle map. After the cams were installed and the bike was mapped I got 178.42hp/102.56 torque. It was mostly up hi that I gained in power, hardley anything down low. I recommend doing it, it is very streetable, not any problems what so ever. You can't really even tell that they are in there until you get on it above 6000 rpms.
Here is my dyno chart that show the difference, let me knowf you have any other questions.

I'm sorry for the miswording I ment the typical bolt ons. I have thr bde3 hindle ,fullbox mod maped,pcIIIr. I just dynoed on a dry shot it hit 207 with a smashed (in half)# 3 tube, The tube it hurt it 4 hp on a motor and broch is out so I will have to waite to redyno.
-
Ok that would make sense because I had 164 and change with the BDE, Small box mod, K&N filter, Pair removed and that was before it was mapped. So you can expect to be in the hi 170's low 180's after a good set of cams. For you application somewhere about a 7 to 10 hp increase.
-
I tried calling you at the number you posted and it was bussy. I bought a factory intake cam for the exhaust side in plans to build a 1397, because I was told the webs would only make 2-3 more hp and for the money not worth it. You seem to like the web cams or they seem to work very well for you. Have you ever tried the intake cams on the exhaust side and had any luck.
-
I didn't bother with the stock cam swap because for me it just isn't worth the money and time(4HP from what I have seen). It would cost about $200+ for a new stock cam, $200-250 for the install, and then another $200+ for the custom map. I would rather pay the extra money for the 10 or so HP with the aftermarket cams. If you are going to go to the 1397 and head work you going to want a good set of cams. I don't think you are going to be happy with the intake cam. To be honest if you are not really tight on money I would try to return it or sell it and go aftermarket, you just aren't going to get the potential out of that 1397 without them. I know it's not what you want to hear, but the dyno sheets show you the increase. 2 to 3hp over stock? you need to stop listening to whoever that is, because it's a lot higher than that.
Here is a link to a thread that Dennis put up a while back with basically the same set up you have with a set of megacycle cams.

Forest - with Dual Yosh cams you'll get about 182 or so with PC, dyno tuning. Expect $500 for used Yosh cams and about $500 for install/dyno time...
-
Yeah that's about right. I payed a little over $1100 with brand new Web cams and got 178+ HP. They guy that put them in wants to re-degree them though he said I should be over 180 and my box mod was a little messed up, real jagged the edge wasn't smooth so he want's me to clean that up too. I just put short stacks in my airbox so I should be seeing upper 180's when this is all said and done.
-
Now are you getting that much power out of a stock bore and piston?Has anyone dynoed one with just the intake cams? I know or herd 4-6 with intakes on the exhaust and 8-10 with yosh or mega cams but has anyone tried just adding the cams and seen a power gain between stock and with the intakes on the exhaust side? Not maping it after the cam install but having it maped for max power then remaping it after the install.
-
my bike is stock bore. i would ask that question in the bike talk section,you'll get more of a response.
-
Hey foresteronw,
which web cams are you running ?
8)
-
Put in the 1397 pistons, send your head to Bill at Port Tech (Really good discount going on right now) and run two intake cams.

hi all
been wanting to have some cams mod either stock or aftermarket...
but after sometime... i decide not to as of now.
from what i read, unless u always high rev the bike ie drag race etc. u dun need the extra lift.
a stock busa is still able to go up to the speed u wanted, is juz how fast. and how much you to pay out of it.
anyway an intake cam mod is a cheap upgrade as compared to web etc. but is also the degreeing of it that determine where u want the power to come.

made a big difference on my bike for the money

the possibility of adding at least 20-30 hp (in conjunction with head work and a good 4-1) is just too much temptation to resist, imo. i'm on my way, with a tsukigi and bazzaz. cams and head work early 09

yeah i know it is toooo much temptation for that!
show us some pic and chart when your project have been completed !! :vl:

i got 11 hp 2.5 tq

i got 11 hp 2.5 tq
cams AND a good 4-1 only got you 11hp?
that sux :(

dave that was just cam only wasn't it

I have a Brocks EX031 exhaust cam forsale if your intersted. If I remember correctly I picked up 6hp on the Dyno with a stock motor with a sidewinder. Normal mods airbox mod/no filter/pc3/pumpgas also ran this in a 1397 with a web395 on the intake side. Bill from Port-Tech built the motor. Made good power but was set up for the Gas. $225 TYD for the cam. No sprocket or bearing. :thumb:

just finished my bike well almost int cam mod murry sidewinder stock bore an pistons cheese got me 184hp 104 tq w/36jet on spray it made 233 hp 134 tq dry kit single nozzel thru filter gen 1

DO you mind sharing the valve timing. Good numbers
