A visit to my engine builder


Recommended Posts

Paid avisit to Bob Johnson of Johnson Racing in Sacramento to discuss this summers engine buildup. Having run many a sim with Dyno 2000 for over a year now, I showed them to Bob. After listening to his suggestions, I re-ran my sims and almost filled my pants :eek: Running a solid street roller cam, single plane intake, 750cfm carb and long tube headers, this future motor should produce, drum roll please....

570 HP @ 6500 RPM and 495 Ft lbs. of Torque @ 5000 RPM. From 3000 to 7000 RPM torque is at or above 400 Ft lbs.

So what do you think? Comments are welcome...

P.S. Lone are you back in town?

Sounds great Mark :D , big power ALWAYS sounds good ;) What are your intended uses/priorities for this Z Dream? (you asked for comments and without your hopes we can only comment "Yup, power's great..")

 

Is this a sbc or bbc or....if sbc and NA then some rather sweet headers and appropriate exhaust will be required to fit the bill. Traction/suspension/cage/brakes etc will all be relevant to the above needs.

 

I've always enjoyed your sig line and have a spin on it..speed also kills so therefore brakes must improve life rockon.gif , till you're speeding again of course :D

 

(wondering what other gremlins are yet to arrive..)

Yup, Scottie has a GOOOOD point. Reason my car has been off the road for 18 months. Make sure you are prepping the chassis and brakes/ suspension to handle that much HP. We often lose sight of the fact that these cars were designed to handle 160+ HP. My car was scary fast with a poorly tuned 383 stroker with flexy floor pans and small headers. With the proper setup and proper tuning it should prove to REALY get my attention. Make sure you address the important stuff!

Mark,

 

Sounds like you have hit the 'jackpot of power' for your ride, but is this just a spicy street/strip racer you are building or a strip only car? If this motor is for the street, how 'streetable' is the combo? I'm just curious because I keep seeing bigger and bigger numbers for horsepower ratings (from all over) and it begs the question of how does a person live with the lumpy cam, etc. I'm all for power and the fun that comes with it, but I wonder if I (for one) can live with the idiosyncrasies of a temperamental motor. Shoot, if you have second thoughts, I'll gladly take the parts off your hands ;)

Fear not guys, I'll be making all the appropriate upgrades to the brakes and suspension, not to mention a full 14 point cage and five point harness! Vented rotors, four piston calipers up front and solid discs at back( I got Maxima brackets ). The car already has Eibach progressive rate springs ( I don't know what the spring rates are). I will need Urethane bushings everywhere and larger sway bars front and rear. As to the motor, it's a SBC sportman block thats been bored and honed 30 over, decked, line honed and has ARP stud kit. The heads are Pontiac Motorsports part # 10033867 these are the same heads run by Nascar for the West Coast Series. They are fully machined, ported and come with 2.100 intake valves and 1.625 exhausts. The heads have been surfaced to yield 60cc and prior to porting they had 196cc intake runners. Since porting my engine builder says they're around 210cc now. I don't have the actual flow numbers for these heads, so I used AFR's numbers for their 210cc Competition package. (My builder says my heads are as good, if not better than the AFR's). These heads will require the use of an Edelbrock Victor High Port with raised runners or similar intake. With these heads and my Manley pistons the Comp ratio should be about 10.2 to 1. Camshaft is still up in the air, but I'm leaning towards a solid street roller with a 282' intake and 292' exhaust @ seat to seat and a 560" lift with 112 Lobe center. I'll need atleast 1.75" long tubes headers with dual exhaust. Is there anyway to post Dyno 2000 files or specs on this site? If anyone has any more questions or comments, please feel free to offer them. Thanks

Ok, I'll reveal my master plan. bonk.gif I am atempting to build a fair weather/weekend only road car that will be very QUICK and FAST with great handling. Body wise, I want what Dan Juday has with a Gnose and aggressive rear spoiler. I'll need BIG fenders to run the 15X10 fronts and 15X12 rear wheels with P7's. That is my Z-Dream...

Z-Dreamer - that's one bunch o' motor you'll have there.

 

For exporting DD2000 output, I've done it two ways:

 

1)

- Do a screen capture (Alt-PrintScreen) of the DD2000 window (make sure it's the active window).

- Paste the cut buffer into a picture package (Paint, Photoshop, Lview, etc.) and cut the number of colors down to 16, crop, etc., save as a gif if you can to keep file size down.

- Put file on a web site and link to a post with {

{url} or {img} (use square brackets, of course).

 

2) Use File/Export and choose the Top game program format (can't remember the title). This makes a nice text file with some of the input info and prints a table of rpm, torque, hp, and I think BSFC. You can cut and paste that into a post directly. If you use {code} and {/code} (square brackets, not curly like I just did) you preserve spacing, etc. on UBB boards like this one.

 

Flairs on that car with 12 inch slicks? Man, that's a ton o' torque for a little Z! 2thumbs.gif

Thanks for the info Pete, the wheels I want to run are three piece IMSA from the early 80's. Thats why I'm considering Pirelli P7's since they are one of the few companies that make a Z-rated tire in a 15X12. I am trying to work a deal with one of my accounts to get them. :D In addition to 14 point cage, I'll need to strenghten the unibody and fab some subframe connectors similar to yours. By the way Pete, this car will have a manual trans and after speaking with some Ford racers they suggested a Tremmec TKO. I questioned their recomendation, having heard that Tremmec's are "notchy", they told me to use GM synchromesh trans fluid and a Pro 5 shifter.

 

Has anyone heard from Lone lately?

I can't speak for others here, but I've been working on and collecting parts for my Z-project for almost two years! I am not "RICH", though I do have a job and I am married (stay at home wife)with four kids aging between 4-11 years old. While my Z is a labor of love, it places a distant last when compared to God and Family! Doing a HybridZ can be as cheap or expensive as you want to make it! I'm cheap by nature and necessity, but that doesn't mean you can't find great deals. Let me stress the word find as to look for, search out, comb the wrecking yards and search on the web. I've found many deals and payed little and sometimes nothing for my parts. Decide what you want to build BEFORE you start and then let the hunt begin!

...Not sure I like being compared to the tools on the fast and the furious, but I'll bite on the "Spending so much money on a car" spin. I make in excess of 6 figures (Just got a raise!!!). I'm 35 years old, have limited college education, and I work for a defense contractor by day and build Zcar parts by night. I don't own a lavish home, it was recently "RE-appraised" for $165,000 and I don't own new cars or fancy clothes. My mortgage is $1000 a month. I bust my ass and have been given some VERY fortunate breaks over the years. However, LONG before (5 years) I was fortunate enough to get a job with my current company, I was a poor government employee making $35,000 per year, living in one of the most expensive economies in the country (Washington DC). I had Zs then and raced them regularly. How do you afford it??? You shop, get deals, horse trade, and learn to do a lot yourself. Now, everyone here that has known me for a while knows that I shop my ass off, and I ONLY purchase deals. Go back and read what I make up above, and then do a search in this forum where I was whinning about paying for Rods and Pistons... Bottom line is to build what you can afford, and then shop your ass off when you can't afford it. I can afford to buy a viper, but I choose to build a V8 Z. One thing I have learned is NOT to get overboard in debt over your project... It isn't worth 21.9% interest rates and rediculous monthly payments on revolving credit debt... I've been there, as have others!

 

I'm not trying to rub my income or good fortune in the faces of others... I was born and raised in a trailer, the same trailer my parents STILL live in to this day. I hope I didn't offend anyone with my statements.

From what Mike has written above, he is obviously smart enough to live well within his means. I know that this is taking this thread on a different tangent (sorry Mark..Z-Dreamer), but if anyone is interested, some highly recommended reading (if you can tear yourself away from your Vissard (sp) and Lingenfelter books), is the book " Millionaire next door". Eyeopening information on how to live your financial lives!

 

Again sorry Mark for highjacking your post.

Mike has good point on not going overboard with you finances on your project. I too was in a similar situation as Mike and I spent alot of money on my car(12K)and the next thing you know something happens and you have to sell your car AND finish paying off the plastic... As mentioned I put around 12 grand in the car and had to dump it for 5200.00 total. Needles to say, I was HURTIN after that one!... Such is life.... I have recently started my life over again with a new career and a new place to live... Hopefully soon I will be able to get back to work on my 78 V8Z

that is sitting behind my other house...

Thanks Mikelly, Tim240Z, Myron, my project is a long-term gig because I purchase only what I can afford at that moment and only if it's a screamin deal. I refuse to be a slave to debt (been there) ever again! I don't post as often as many on this board, only when I have a question or can offer advise or in this case share my good fortune (great buys) and future plans/dreams. I logon to this board almost everyday, HELL it's my HomePage! I truely love what this board offers and stands for and all the great people that make it so. Sorry I sound like a preacher, oh well, maybe some day!

If anyone knows about the evrr shrinking budget it's me! I feel no animosity toward Mikelly or anyone else that is making a decent income--more power to them! I do, however, want that for my own family too smile.gif Heh heh, someday...

 

Myron, good to see you back and posting again--hope that everything works out an you get your car finished sometime in the next year or so.

 

Mark, please see my email to you.

Mike - Congrats on the raise - I know the BS you put up with and you earn EVERY PENNY.

 

One of my secrets is doing it slowly stretches out the cash outlay. Not a plan, just a reality for how my free time comes about. :D A pil of money over 11 years is a bunch of small piles :D . I wish I knew how to find deals like Mike and others. Part of my problem is being able to trust strangers on ebay when buying big ticket items.

 

Z-Dreamer: I've heard bad and good about the Tremec 5spd's notchiness. It seems as time goes on I hear less bad. And yes, all the experts I talk to (Darkhorse Performance, Fortes, Hanlon, other Tremec builders) all say the same thing - GM Synchromesh and Pro-5.0 or Steeda shifter. I hear the B&M Ripper is nice, but makes a lot of buzzing noise. I also hear about a vague 2-3 shift, but the Steeda and Pro-5.0 are supposed to be good for fixing this.
