Merc 1000 SC cam specs and Straub
 

I asked for and got the cam specs and bought 900 sc cams however wondered if anyone had cam card or even lift and duration. I thought they were same cams but there not. I believe I read somewhere they are like .714 lift however that's all I could find.

Other question I have is if anyone has used Straub for custom grinds? If so results...

tks
john

to bad bob madera got run off this site,he would have the answers to you,r questions.give him a call john,pm me if you need his number.

Was Straub one that got banned ?

252 257 670 lift on both.

straub and scott foxwell both got banned.

Don`t miss him one single little bit . Glad that snake oil selling , lying, full of $hit, drama causing , behind your back $hit talking, pile of dirt is off this site, everyones engine is better for it.

they at least had some good tech info to share but yeah that coulnd go on with ol BUTT hurt bobby complaining about competition in the backround.

dan,can you say what you really think,lol.like him or not makes no difference to me but he is well versed on the subject.

bobby had nothing to do with it but it,s water under the bridge around these parts.

He`s well versed in taking peoples money and telling lies maybe.
I hope he`s somewhere mopping floors using his big words to tell everyone how to mop properly using the correct pattern and applying the right pressure at the right angle and the mop water bucket is hopefully thermally stable.
Probably tells everyone he has a mop shop and is able to test mop breaking threshholds while installing the proper mop heads and absorbency in his mop shop (kitchen table)

He can ship all his mops right from his shop (10x6 lawnmower shed) by in reality everything is drop shipped from chinamops.com

I like my story better

that's some funny chit and I here ya. Every now and then I'm on yellow bullet and Straub - Foxwell seem to have it together for the most part and bring some pretty good knowledge to the board. I forgot they got banned or it was before my time here or when I was on a boat break. Just looking for another grind hoping to go in circles at wot. Hah. Actually to compare on dyno.

ok Tks. I thought they were the same but then ran across an old OSO thread saying different.

people over there are seeing thru them,,all they do is take other peoples combo and claim them for their own.been doing it for years,,they have a good data base of what works and what doesn't.its amazing how much power you can make w/ 20% correction factor.

I have seen Foxwell and Straub on drag race forums for years and was surprised to see them on some boat sites as well. They do have some spirited conversations on the forums and glad to know why they are not on this one.

I have had a good overall experience with Chris Straub and Scott Foxwell.

First and most important has been their excellent customer service and communication, before, during, and after!

Second has been their parts reliability....doesn't matter how much power you make if it doesn't last.

Third my RPM and torque curve was on target, and useable for my application, boating style, hull, and props.

​ I am not saying that they are perfect. Like any company there are good and bad reviews. They did fall short on my peak HP goal but achieved our torque goal, peak rpm, and most importantly reliability. I'm honestly not sure if more "peak" power would benefit my setup especially if I lost somewhere else and since my top speeds and acceleration are in line with what was expected.

They also failed to meet our timeline goals, but who in the Marine industry is on time anyways! What's nice is they included free overnight shipping on parts that were late all while keeping in touch and NOT making up excuses. it's refreshing to hear someone accept responsibility for their own actions.

Chris also did a great job reffering me to other companies offering products they don't. I met some great people and products through these, unfortunately the carburetors he subcontracted failed to perform as promised. Chris and the carb builder fully supported my Dyno tuner through this and when they failed to perform I was given a FULL refund including shipping both directions.

thats interesting. My impression is they have pretty good reps, and jones. Whoever that is.

I follow a bunch of Scott Foxwells posts on facebook. The guy is heavy into cylinder heads, porting them, and so on. I am in several groups where there are some pretty big names in cylinder head world, and foxwell chews the fat with the rest of them on cylinder head design, and so on. I watch him talk about different techniques on various valve grinding machines, and things of that nature. Certainly nobody is laughing him out of the room there.

As far as Bob Madera being RUN OFF this site.......Bob was not banned. Bob had every opportunity to defend himself. Instead, he had friends like Brian Orlandi do it for him (until brian found out bobs been lying to him and cost brian tens of thousands of dollars). He sat back watching his current customers, former customers, and potential customers, battle it out online. He sat quietly reading, but man, once you got him on the phone, you sure got an earful about what was going on. I been here 13 years. I can count on my hand, how many times I have seen Bob offer REAL tech advice on the forum, for all to see. Im not talking about some fancy excerpt he pulled from a book and shared, or some "specs" on certain cams, or a post relating to a product he sells. Its not like he was here telling guys how to plumb fuel systems, how to rig #6 boat, what differences prop diameter and rake can make, how to program a custom ignition system, his personal experiences on the water, or anything like that.

Maybe Im nuts, but sorry, I don't think the days of "CALL BOB M" defined a good tech section for DIY'ers here on offshoreonly.

I believe the 1000SC, was pretty much a 900sc, with 12lbs of boost and race fuel. 900sc was 10lbs and 92 octane, and a poker run style engine mercury offered to the public. The 1000sc, I believe was a race course engine. I do not know if it had a larger camshaft . It could have had a 714 lift solid roller in it. Probably not something I would want to run in a pleasure engine.

ya know what,i really don,t give a chit about how much some guys don,t like bob for whatever reasons they have,i simply stated that it is to bad he no longer visits this site because like it or not he has a lot of knowledge and could have answered getrdunn,s question.i think some guys on this site need to chill out before you stroke out,it,s no wonder people are leaving this site every day.yes joe i understand you don,t like bob, someone brings up his name you go crazy.whatever dude,like i said i really don,t give a chit so carry on with the very necessary rant.just a fyi,a lot of oso members don,t want to be bullied so they dont say anything but man ,**** it never mind.the floor is your,s go for it!

Just in time.

Going to be 12*F here in the AM.

Ya were chilling in the north for sure. This weather sucks monkey balls. Anyway ya let's just stay on the subject which is pretty much covered and I do appreciate the post regardless.

Aaaaannnd it’s officially winter. :)

Did you already buy the 900 cams?

yes I did but not really what my head guy wanted for optimum performance with what he's done with the heads.

what does he want?what hp/tq are you shooting for?

Looking for 900 plus. Static comp is 8.2 and probably 6-7 pds boost. i thought the cam would be close to right on considering merc had to spend some R&D time but jim would like to see a little more lift and less duration. I understsnd what his angle is but.... He has a great grind for his NA 565 TR that peaks hp right at 6k. 236/242 I believe. I think his concern is with higher duration cam port velocity gets lazy.

So how much lift is he suggesting with that duration? Hate to see you have to sell them on Facebook.

They are older tech and are harder on valvetrain than some of the newer grinds.

evidently there was a couple different grinds that went into 900's according to norm at cfs (competition fuel system). The earlier ones had some pretty steep ramps and very quick to come off and back on the seat.

New springs and lifters every 50-75 hrs but if I'm not mistaking that hasn't changed even today. No real biggie as that's about every 2 seasons Btwn work and weather yet if there was other choices without sacrificing power and easier on valvetrain I'd consider.

Woah, sorry I'm late! "I was in the shop running the Spintron."
