Just caught up on this thread... I can't wait to see the dyno results - let me know when you head up, I might try to join

Also - awesome video! I agree with jmartinez, except I'm alot closer WOOHOO!! Do you charge a consulting fee?

Mr. Reese you already know I love running my mouth via consultation on these engines you ask and I'll talk The dyno should be interesting to say the least I will let you know when I go.

Okay I am moving forward slowly . Nonetheless here is an update brian crower wanted me to check out their head gasket and to see what I think about it . It's of very high quality to say the least. It is somewhat between a stopper and regular head gasket. If you take a look at the picture you will see there is a small bead around each cylinder just like the Hks stoppet. Since I am sold on the stopper this got my attention. I put it on the engine slightly snugged the stud and then loosened them just to see if it would make a ring around the combustion chamber in the head like the Hks stopper and it did this mean nothing but seal so I am going to give it a shot I am very impressed with it. I also knoticed that it matches the combustion chamber well when put on the head. No overhang that could create a less than ideal condition with the air fuel mixter on firing stroke.check out the pictures.

No overhang that could create a turbulent condition with the air fuel mixter on firing stroke.check out the pictures.

what do you know about that? turbulence is a good thing. The overhang would be a hot spot causing detonation.

I gasket matched the combustion chamber to the head gasket since the engine was bored 40 over. bigger bore than cylinder head combustion chamber is not good can lead to many issue. CORRECTED POST! correction in post 158.

Na Bro you got it wrong I gasket matched the combustion chamber to the head gasket since the engine was bore 40 over. a bigger bore than combustion chamber is not good for mixture do your research then come back and correct your post.

haha oh boy. There is nothing wrong with my post. Overhang of either will cause a hot spot. And turbulence is good for mixture. I believe that you need to do YOUR research, as YOU'RE the one who is wrong. I have already done, and doing my research. My Phd dissertation is on the development of a monovalve direct injection gasoline engine. That doesn't even count the various white papers I have submitted recently....

By the way, you better catch up. I made 650 the other day.....

Lemme see if I can get this right -
bastarddsm - you're bustin keltalon's butt, not because he was pointing out that the head gasket has no overhang (which he was right on it being good), but because he used the word "turbulent". I understand what you are saying - turbulence causes a better mixture. I also understand what keltalon meant - it can cause a restriction/disturbance to flow in the combustion chamber - also a meaning of turbulent.

I took a glance at your profile and am grateful that you are part of the dsm community - you've contributed alot to the community and regularly provide a great amount of help to us "newbs". Keltalon has done the same and I greatly appreciate him documenting everything in this thread - again, it helps us all out. I'm seeing this as a difference in wording, but still saying the same thing - keltalon did it right by not having overhang or a bore that was smaller than the gasket (underhang? ... that just sounds funny) but rather both matching up so all is healthy in the combustion chamber. Thats the point, right?

Much appreciated reese for the clarifying of post I will make necessary correction. I know what I was trying to accomplish. I miss read this statement from an article in the sports compact section but the end result of what was done is MISSION ACOMPLISHED here is the quotation for the benefit of the boards I will corrects my post earlier Thanks reese!

"Some head specialists also modify the quench zones of the cylinder head's combustion chamber. The quench zones are the flat areas of the cylinder head where the piston comes in close proximity to TDC. Pentroof DOHC cylinder heads typically have four quench zones at the ends of the combustion chamber. Quench zones promote more complete burning and reduce the likeliness of detonation by increasing turbulence of the fuel air mixture as the piston comes to TDC by squishing the fuel air mixture toward the sparkplug and away from the end zones of the combustion chamber. This reduces the amount of fuel-air mixture near the ends of the combustion chamber where it does not completely burn (thus being wasted) by pushing or squishing it toward the centrally located sparkplug where it can easily be ignited. When heads have additional quench area, they normally need less timing advance to make power. Thus a skillful tuner can tune the engine to be further from the detonation threshold, making the engine more reliable."

Still running that "JOHN BROWN" I see I think you are bored and you seem to have this fear of someone else making more horsepower than you Dude that is childish and somewhat bipolar. Like I stated earlier If you happy with your current HP goals then go out and enjoy your car please don't TROLL in my thread your not welcome here


Fellas I will keep the up dates and pictures coming its getting pretty close to completion just waiting on kiggly HLA, kiggly 6 bolt trigger switch, and MAP new H-11 head studs to arrive

I ended taking the cyclone manifold to be powder coated instead of just glass beaded also took the valve cover 135.00 for all 4 pieces not bad! wrinkled red on valve cover and wrinkled black on manifold.

 

[keltalon]

I can't help it. One last shot of the 30hrs port and blend wo

Very scary situation but you seemed to make the best out ot it. I'm going to replace my lifters after tmw, and i'll take it from there.

Blah blah blah about quench.

Lol Sport Compact Car isn't wahat I could call a credible source, but there info on this isn't bad. That doesn't change the fact that gasket overhang has nothing to do with quench, and the biggest point is YOUR HEAD AND PISTON COMBO HAS BASICALLY NO QUENCH, the small edge of the piston does not contitue a quench area as there simply isn't enough area to do any thing. That's even assuming that you bother to measure your p2h clearance and had the block decked to get it down where it should be. Having a p2h clearance that is too large is actually worse than having no quench, as it bottle's up the end gasses and allows them to surface ignite easier. Our engines actually have a too small of a bore to ideally utilize "quench" technology, as the nessecary size valves end up taking up too much of the chamber, and also have to be at a large angle which creates a tall chamber, where a shallow chamber would be ideal. The closest piston to having quench pads are the Magnus pistons, followed by the JE's.

From what I can make out of your other post's is you meant to say that you unshrouded the valves. Leaving the head to overhang the gasket would have actually INCREASED your quench area, though I doubt it would have been beneficial at all in that respect, I believe you did the right thing by unshrouding the valves.

Speaking of things like that, did you smooth the casting flash around the seats? I usually take two additional top cuts there a 70* and 80* to blend the seats into the chamber better. I have done it by hand, but its a pita. I also put a plug in it and grind the plug boss down flush with the plug so it does not shroud the flame. Does it help, #### if I know, but I sleep better at night for it.

Still running that "JOHN BROWN" please don't TROLL in my thread your not welcome here

What does that even mean? I'm definatly not trolling, just telling you how it is.

Well you are now on my ignore list TROLL! A "troll" is a person who posts content for the sole purpose of baiting someone into a hostile confrontation - they do this for entertainment, to make themselves feel more adequate, and to get attention. It can be blatant or subtle". Straight from the forum rules. Last time Go away I don't have time to play with you right now maybe later I am trying to stay focused on making this power when my engine is done I will take you off my ignore list and go a few rounds with you through PM since it seems that you want the championship title or something I don't have a problem with that I can hold my own very well right now I have an engine to finish up.........

That port job looks superb!!!!

As for your comment, we have a ignore list?

Yelp you can click on the member name and scroll down and instead of sending them a pm you just click and add them to your ignore list and everything they post on the forum cannot be seen by you this is an awesome feature because it help you to stay focused while on the boards:thumbup:

Okay took a little time this morning and removed the Hyundai off my valve cover now its ready for powder coat

Thanks for telling me that. As for the valve cover, what color are you powder coating it?

 

[keltalon]

Wrinkled black with machined letters.

 

[jmartinez1228]

You had a vid up on your youtube page that said something about having excessive crankcase pressure due to loose baffles in the valve cover or something like that. Said you were going to fix it,

What was that fix that you were talking about?

I drilled out the rivets and pulled the baffles completely out cleaned it up and resealed the baffle back in using red gasket maker. I have a thread on it somewhere here ok tuners.

Thanks Mucho! Took a lot of blood sweat and tears

 

[keltalon]

Color change valve cover silver vane valve cover textured black manofold.

 

[TSITurbo95]

Silver vein is by far my favorite powder, love the look it gives!

Yeah If you keep your oil changed you will be just fine

 

[We're on Boost]

Keltalon, are you using a regular 2g MAF?
