As requested, a new string.

I will be posting the full string on my web site in a couple of days, just to make sure nothing gets lost.

I have an idea for the valve cover

WWW.STARQUESTCLUB.COM

[87quest_stv]

hehe.. well.. umm. nice idea.. but i'd rather it say something like..

Starquest Racing.    or Starquest Performance
         DOHC                            DOHC

[MainstreaM]

why not leave a raised boss so you can machine what you want into it.

Kane

I like that idea.
Kinda low on the totem pole right now though, guys. I mean, considering everything.

[Technology]

you should just have it say DOHC and the model number i.e. "0001" and "0002" and so on and that sort of thing. don't put something on there that makes it look stupid, which would be soemthing with ".COM" on the end of it

[smog]

I gotta agree there. Just t throw 16v DOHC or something

[johnfjamerson]

I think it may just say, JJR on one side, and (thanks for the idea...) a small production number on the other. A matching number will be presented on the head in the same area as well. Still just thoughts, as my shop in Idaho seems to be taking for ever. I guess they are calling everyone they know, including thier very own contacts at HKS to see what can be done. ---I am still looking for guys (besides Justin, and myself) who can put down some cash to make this happen... So here is what I propose...

Any (person) who puts down money to get this of the planning table, will share the markup on the next run. As you can imagine, once this gets going and word gets around, a lot more people will want one. I count 17 guys on this fourm that said they want one now. Say the first run (is done at cost) for 20 units. Think of it like a discount, to be part of the first run, you will skip the markup.
Any run done thereafter, (and believe me, there will be), the markup will be split between the (first) investors.
So, any who get into this in the beginning, will not only buy themselves a new head, but make back thier share of half the profit off the next run. Incentive.
'But we need numbers'....
$2000 for head.    run of 20.   20% markup on second run of, say 20.
$2400 for second run head. each of the original buyers makes back half the markup. thats $200. so its like buying a head for $600 off. ah, but wait, if only 5 people get this satrted, 20 heads, at 400 markup. thats $8000. 5 people split half of that between themselves... thats $800 a peice, back to them. that, would be like buying a head at $1200 off Retail, for only $1200.   And iff the second run is larger, well then, you do the math.  (This is all asumming a $2000 initial price tag)
---Who wants to be an investor? --oh, plus we can make this contracted... to garentee the profit sharing... and the sound investment of the money.

Tell me what you think guys... Im still fishin. ------but we only need about 5 guys to get this going.

[Mitsuracer1]

Hey, If you can figure out how to keep the combustion chamber the same size and shape and still be able to keep the A/C It'd definitely be worth the money. Posibly a new cast?...Just my 2 cents.

[johnfjamerson]

chamber will not be the same..... it will be a pent-roof, and a bit more acute angles on the valves. The a/c will still be there, all you will need is a longer belt.

[Joel]

While I will agree that pent-roof designs are less detonation prone, I don't believe they are less detonation prone in shape much less then the hemi design. You can't stuff 4 valves in a true hemi without a valvetrain logistical nightmare, so pent roof showed up.

Most of the design considerations that followed the pentroof design would lead most to believe the cause-and-effect relationship of a lower detonation threshold was due to shape, when, if I recall right was more due to the introduction of quench area.

Does this DOHC head have plans to introduce quench area, and if so, is the consideration that you will HAVE to build the entire motor around that amongst the other changes being thought of? As in... whose going to make the pistons after all those other "must haves".

I'd be in line right now for one if I wasn't on my last financial leg right now. Pretty much a 1 person income in a 3 (almost 4) person family... Car enthusiasm sure doesn't get funded real well that way.

Joel

[johnfjamerson]

A small quench area will be there. This will not be a problem when you consider the way the intake charge will enter the chamber. Even with the primitive stock TBI setup, the two valves will turbulate the charge as it enters the chamber, and mix it more thouroughly. No rich spots, means less change of detonation. Plus we still have these crazy dished pistons, that at the most will have the compression on this head to about 9to1.
The quench area is only about (if looking at the surface of the head) 3 to 4 cm2, spread on both sides, (intake and exhaust) With a pent roof, it is very hard not to introduce a quench area, without making the head rediculously wide.

On a different note, My pride of a 140K motor and 16psi has ended  >:( I have developed a very bad piston slap and rod knock. So I will not be driving it for a little while. As you can imagin this is bad news, sice the funds i had availible for the head will have to be (partialy) diverted. But no one has comented on my "subscription" idea. I really do want to make this happen, so everyone else who wants this to happen, give me some ideas.


There is also a meet Saturday in Seattle. Not a big one, but still a meet. I will be talking more in depth with them, and see what they think. afterwards they will post thier input, for all to see. If it helps anyway.

CU

[johnfjamerson]

Man, Im a little P-O'ed. That shop I am dealing with, is telling me it may be 'an all winter thing'... meaning the prototype wont be completed until next year. I am now looking into other shops, and have found one in my area. The got all excited about it, but cannot really give me a price quote, as its a day be day kind of thing. This did say, however, It wouldnt take more than about 6 weeks. But it may be a bit steep, around 19 large or so. Im still lookin guys.

I am gonna call Team Sakura tomorrow, and see what they have to say.

Justin: As soon as I know more in detail, I will draw you up a plan for 'presentation'. ok?
Peace

[johnfjamerson]

Ok, talked to Sakura, They are looking onto seeling it to me, oh, anybody wanna but an enigne/tranny combo with computer turbos, and TONS of spare parts that ran a 7.41!!! only $16000... They are changing from the 2.6 to a V6 powerplant of some kind. eh.

Anyway. Here is the news.

A WORKING HEAD will be done by the end of August.
Yes. On a car, driving around. This is being done out of my and one others own pockets. The cost for a production head will not be known until that time when the head is run on a car. Not even a ballpark can be estimated at this time. Sorry for that guys.

In the mean time, I think the posting will be slow untill that time, I will answer any questions, and give news of the progress and updates.

Keep the rubber side down.

[importwarrior]

good news! thanks for keeping us up to date.

[johnfjamerson]

Well crap, and I was looking forward to haveing this head on my car in a few weeks, but it appears that while working on an essential part of the girdle assembly, they damaged it (the girdle) beyond repair, and a new one will have to be manufactured.

That will set me back at least 3 weeks. Damnit.

Just thought I would let everybody know.

[backslider]

If this falls into Feb of next year, I will be up for it.

[importwarrior]

sorry for hearing that

but i wanted to say thanks for the update!!!

[Sonny_Jim]

John, that sucks. Three weeks aint nothing though. Just think, more time to break your motor in. Well, if you need help with anything, let me know.


Jay

[johnfjamerson]

...Well, if you need help with anything, let me know.


Jay

heh, how about a few thousand dollars?  ;D
Thanks though bud. -oh, my car should be up and running in three weeks. ran into a financial snag, so i have to take another check. bah! ...but at least the headlight mod is finally done. it took me what... almost 8 months!! lol
