1100 head vs 1150 head power differences

[Guest]

This is going on a 1640 motor, with flat top pistons for bracket racing. The spigots are 44mm inside diameter & the valves will be 31mm intakes & 28mm exhausts. With 44mm Lectrons & 12-1 compression it should run easy 8.20s in the quarter at about 165-168 mph. I do the same work on street motors, on a smaller scale of port mind you, but have never had an issue with the epoxy. I'll add more photos after I get the epoxy in the floors too. Ray.

Ray,
I have to ask why such a big head and pistons to run top gas (8.20) index? When 1425cc and 29.5/24 is all you need to go high 7's at 168 mph. I hope that et and mph are what your hoping for with the throttle stop on it.

31/28 valves sounds like your building a NO2 head.

No, the 1150 head just allows you to run a 1mm bigger intake than the 1100 head. If you already have an 1100 head & want to use an 1150 head it will cost you $300-500 just to buy an 1150 head & valve cover. I can do a LOT of work to an 1100 head for that extra money. Ray

I disagree with you on this
The 1150 head is miles away from the 1100 head in the size of the intake port

Actually, it isn't. The 1150 intake port is only a little bigger. I only have about 20 or so of each. I've had just about every Suzuki head on my bench & the 1150 ports are a LITTLE better, not a lot. I also build my motors big & overkill & then run them easy so they live. I'm not running pro stock so don't need or want a bunch of rpm. Ray.

What I mean by a lot better is that the 1150 head intake port can be opened up to 38mm without making it to thin to hold carbs and the 1100 head is only 38.5 mm on the outside so you would have to cut the intake port off and welding larger ones on it to achieve the same size port. If anything the 1150 head is closer to the GSXR/Bandit head than the GS1100 head IMO.

1150 N/A head 29.5/24 valves 420/380 lift cams cams 1425cc 13.5 to 1 compression car tire chassis shifting at 10,700 rpm runs 7.87 @ 168mph with a 1.17 sixty footer. I don't think that is winding it up to far.

The people I build motors and port heads for are usually on a tight budget and don't have extra money to throw at me to way over build for the times they want to run. Nor could I do that to someone just to make more money and still sleep at night. But I can say that every head I have ported has gone quicker and faster than they were hoping for

I have a bunch of heads in my garage also.

I don't do anything just to make more money from anyone so where does your comment come from? I build stuff that will LIVE first of all & will run quicker than what they are expecting. Do you have a problem with that? I ask because I have NO idea who you even are & wonder where the comment you ADDED to your post came from. Ray.

WAIT,
let me get some popcorn:twistedevil:

I made that comment because you told the op that he would be better off paying you more money to do more expensive work to his own 1100 head instead of starting with a better platform of the 1150 head that to me tells me that you don't care about any body's wallet but your own. The motor build you bragged about 8.20 @168mph. I would be ****ed off if you built a motor that extensive for me. and it only went 168mph. As far as not knowing you I have read a lot and I do mean a lot of your post and know you quite well now. It is me you know nothing about.

Now tell us what rpm are you going to shift at to slow the bike down to 8'20's?
Did the customer tell you to build the motor that extensive but slow it down to 8.20 index or did you suggest it because he had deep pocket?
The fact that you got all defensive about this tells me that you try to up sell your work or you would have said something like. I know it is over kill but I am doing what the customer wanted even after I told him he could achieve the same results with a lesser build and save some money and then my next comment would have been an apology and I would have said to you you have to do what the customer wants. Not huff and puff around like a 10 year old. This is a discussion right?

It is MY motor & you DON'T know me so stop ASSuming. Ray.

 

[rapidray]

And I never bragged about anything. I just put up some pictures of a head I am building. Where did you get bragging from that? Also, telling someone they can get plenty of power from an 1100 head is SAVING them the cost of looking for & buying an 1150 head. Lastly, Mark, isn't that your name, for the power level he is asking about, he doesn't need to use an 1150 head so it costs him less. Ray.

I know you don't like anyone that disagrees with you. Or ask you questions about one of your builds.
The difference between you and me is I know a lot but I always like to learn more and am willing to admit when I am wrong and you seem to think you know it all

So tell us what rpm do you plan on shifting your 1640cc motor at?
Just answer that one question

Ok I will admit you didn't brag about it but you did give the impression that that was a good build to go 8.20's
I still disagree with you on the 1150 head. You can find 1150 heads for $400 and then sell the stock 1100 head for $200 and you only have $200 into an 1150 head the he could just put it on stock if he likes or get a nice clean up on it or take it to a higher level but it is a better platform to start with and you can take the valve cover off and not have to buy a new gasket every time you take it off

Who is Mark? My name is J.D.

 

[rapidray]

Well, if that's the case JD, I will sell you EVERY 1100 head I have for 200 each. I havent seen one sell for more than 125 in 2 years, and I watch for them all the time. You build tjem your way & I will build them mine. I have no failures & no complaints about how my engines run. Good luck with yours. Oh, and I learn new stuff every day. I just know how to make 1100 heads work well enough that 1150 heads arent a requirement. Ray.

 

[tom]

well i have both heads and motors now i have my hands up on witch one to build .i want to run in the 9s with my 1981 but now i need a com bow wich one

 

[rapidray]

Use the 1150 motor Tom, it already has a welded crank. Ray.

Either motor will run high 9's with a stock motor with a good street ported head no epoxy just a good clean up and a good set of carbs and a good chassis set up an air shifter is very helpful also
Now when I say stock motor you still have to do the bottom end weld the crank and clutch basket under cut tranny.
I am kinda partial towards the 1150 motors.

 

[blowerbike]

my .02 worth...
i love the 1150 engines and in the beginning of my hi perf journey i had no money.
i would get the most out of the stock head and pistons and just add drop in's and RS mik carbs.
all my motors in the early days never had the head removed(dead stock).
pre internet and all this BS talk where everyone is an expert with a foot long sausage...
heavy 1150 street bike...no airshifter..16t front/stock rear sprocket..10.40's
3" over arm and 14t front sprocket...10.30 flat.
same engine in a longer a little lighter foot shift 82 chassis..9.90's
same engine in a small tire drag chassis with a heavy rider...950's

if a person spends more time than money on what you have to work with(given it's a good platform) and buy's used parts when available then a person can actually learn a lot about carbs/cam timing/gearing/chassis set up and so on.
ok my dlck is kinda small for this conversation so i'll let all the big boys carry on
