Well after having a power steering assist rack in my car for seriously years.... it's actually hooked up and working!   Yes!   At first I thought manual steering would be better for autox, more feedback which I thought would help car control.  After a buddy I raced with suggested I listen to the Cone Coach podcast (I love podcasts, from science to racing they are all really fun.)  One of the hosts mentioned if given the choice even in his stripped out race only Miata he would never remove the power steering.  He says something to the effect of.  

 

"Yes, maybe the manual car being lighter and having more feel could do a theoretical do a faster lap,  overall... Although, given the few runs we get, it's better to have a car you can drive to it's full or almost full potential ever lap.   Not hope for a hero run."   

 

Also note he's a SCCA regional champion and says his Miata is the heaviest one in the class.  Some things he says don't pay to remove.  

 

I agree.  I find myself on some courses grabbing wheel and just basically turning as hard as I can, sometimes it works sometimes it doesn't.  Also trying to shift can be tricky with really heavy steering.  The race this weekend was canceled due to weather.  I'll know soon how I like it!   I didn't do the best install every.  Just used some junk I had laying around.  Since I will be boosting the car soon.  I figure I can clean things up and respray the bay then.  Some pics of the project.  

 

 

First issue... No belt room

So I just moved the motor back a little.   Seems every project requires the mill!

The lines are of a 86  weird how they bolt right up to the SR pump!

Almost done!

My helper passed out.

No test rides yet.  You can see it covered in snow.  My siblings came by and helped me dig it out and get it in the shop.

It sure does steer a lot easier!  Still takes a bit of force.  Super excited! I wonder how street driving will feel?  hurry up and melt!!

Jeff, my 620 grew to 3,400 pounds with the SAS and all and with 33" tires it was a monster to park. Jees that's 700+ extra pounds plus my ass. I made up a PS using a 280zx box and pump from a D21. The point is I could throw that truck into the other lane with the flick of the wrist if I had to. I used to scoff at PS...it was for wusses but not any more. Anything that makes driving easier reduces fatigue. Anything that makes driving faster is... great.

Looking forward to watching this rear suspension come together!! ?

 

I saw a rough make of the new 510 crossmember. I had a difficult time not just adjusting it back and forth on the table. Good idea and well designed.

 

Im saving my money up!

I'd sure like to test one out.. just to make sure it fits on a 68..

Had a blast an the NW Nissan event.  They had a autox at the Evergreen track.  Of coarse I had to attend.  I knew I had a good chance of placing on the way.  It was so rainy.  Most guys seem to not know their cars limits in the rain.  I had a 5 second lead for the first few laps while guys found their cars limits. haha.  Brought my boy.  Who really wanted to ride along.  He has to be 14 before he's allowed to ride.  My wife planned on sitting with him in the bleachers during the event.  To cold and rainy so they went home.  Still getting used to the power steering.  Sure like it though!

HAHA he rolled down the window and it started raining on him!

Then I rode in my buddy Aaron's drift car.  There are 3 dudes in his team.  We were the last car.  WOW!!!  SO MUCH FUN!!!!!!  I'm so building one next!  I can see why young guys drift.  Beyond fun.  Aaron is an amazing driver.  He's been driving for around 10 years and still has his original S13.  We were inches at times away from the other car!!

All has been good with the car until last week.  My sister accidently backed into the door 😞   Got my boy to call around in search of a door.  This week we should get the new one painted up and on hopefully.    If anyone has a OG paint tan drivers door or passenger fender let me know.  I'd love to have the orignal look back.

Well since its damaged I'll buy it from you

 

Can't sell it.  I love it to much.  Brought my baby boy home in it :)

 

 

 

Got the door stripped.  Gotta do some welding tonight, then prime, mud, prime, paint.

Time to travel farther down the rabbit hole.....  The more I learn about race car handling vs. street car handling the more I realize that giving up a bunch on the street can make your lap time better.  Which on paper seems great, until your driving a loud twichy car that catches ruts and overall could be more enjoyable to drive day to day.  I've experimented a ton!  Which includes extra rear toe in, like Keith. which with my lower power levels I honestly couldn't tell the difference between stock rear tow and mega rear tow.  I did however notice my car drives much better in the rain on the street with stock rear tow.  Maybe after it's boosted I'll do further testing.  I tried front toe out, yuck!  Even zero front toe sucks.  so much less darty with front toe in, and I honestly don't feel the difference at the track.  

Things I did notice, rear damper change, wow!  That was crazy.  Fancy seat, maybe one of the best upgrades.  Softer springs also very noticeable.  Steering box to rack, more noticeable on the street but the faster lock to lock is key.  Added power to the rack.  Also very noticeable.  I expected it to take a bit to get used to autoxing.  Nope instantly adjusted.  Lower gears was also a big help. 

My very first goal way back when I did my first rack swap was to get my 510 to drive as good as a new car, well on the street.  Which turns out is still my goal.  We have a Nissan Leaf, which is about the best cheap car you can buy.  It drives awesome around town, great feel and return to center.  I'm always telling Sam, "I just want my 510 to drive as good as the Leaf."  So we always talk about what could be different.  He says it could be the electric steering helping out.  I don't think so.  Sam's Pulsar drivers really good too.  The common theme between the Leaf and the pulsar (besides front drive wheels) is scrub radius.  Which many have brought up before.  Baz said that's why he used the Skyline struts, they have a higher king pin inclination.  I wondered how far off my scrub was.  So I made a quick Solid Works sketch of my strut.  WOW the scrub is crap!!  Check it out!

Most books say no more then 1"   I'm going to have to dig out my Herb Adams book! 


Sam has higher offset wheels on his car and I can feel the difference driving it.  


So when you have a suspension issue the answer is always "what do new cars do."  The S13 has a great solution.  Kick the strut back to add more wheel clearance to run a higher offset wheel. Seems most cars still use the same method.  My plan is to run ZX struts (1/2" gained with the struts) then a higher offset wheel.  The other cool thing is since the S13 struts have camber adjustments at the connection near the spindle I can use the camber plate to see what the effects of different King pin inclination/ scrub feels like.  

Got these from Rich YEARS ago!  Thanks buddy!!!!

These are made by a Z car company.  Perfect solution.

Also the Tokico alumni 5 way adjustable inserts suck.  Can't wait to ditch them!!

Those adapters are super cool. They're made by a company called rt.trackpro. Their web site is https://responsetype.com/shop/. I only got the website to load properly once. They have a bunch of cool products, I hope they are still in business.

They seem super cool.  I hope I feel the same way after I have them installed :)

I hope you do too since I pulled the trigger on a set. I'm interested to see how much more tire clearance you can gain, if you can reduce the scrub radius and still be able to add the camber you want.

Very interesting.  How are the large steel adapters held into the strut hole of the steering knuckle?  I don't see any bolt holes or welds.

They're welded to the strut tube. You can see it in this link.

Thanks!!  They don't open the bottom up to weld it there too, do they?  I wouldn't think so.  A lot of work for a bit of overkill.
