Power steering pump?
 

Hi Mark,
Are you using a stock ls9 powersteering pump? If so..... Are you using a flow control valve to knock it down to the 2.0 gpm?

I have an LSA and that motor uses a zf pump that seems to be a lone wolf. A normal type ii flow control valve does not fit. I'm trying to figure out what power steering pump to go to and also fit my LSA accessory drive. My steering is redicoulously easy.

Thanks for your time...... Dan Fisher

I have used a stock LS9 pump on the last 3 LS9 builds with a Detroit Speed rack and have had no issues. I never tried the flow reducer.

What rack are you using?

Mark

Mark,
I am currently using a Ford rack (tci pro touring suspension 67 chevyii). I've been told by 3 people now that I need to reduce my pump flow down to 2 gpm.

The stock LSA pump flows 2.7 from what I can find on google.

I called DSE and asked if I could just go to their rack and the gentleman told me that I should also reduce it down to 2 gpm. I'm sure going to their rack will make it better. I believe their rack pinion valving is stiffer than mine.

I also talked to AGR performance and he also told me to get the gpm down and go with a 15:1 and. 230 firm pinion valve rack and I would be much more happy with the "feel".

I find it interesting that yours is not reduced. Maybe with it being from a vette the steering is set up a lot more firm compared to the the cts-v
caddy?

Would love to see more pictures of the wheels on the car. Without the masking on the car. I really like those wheels and have thought about them but then decided to just go with Trueforged 3pc wheels. But I may hold off now until I see more pictures of the forgestars mounted on this 69.

Oh yeah. What are the offsets front and rear? I can't wait to see this car finished. Everything you touch turns out badass. I like the way this one is progressing.

Mark doesn't give out his backspace measurements for wheels. He does a lot of things to tweak the fitment like roll fenders lips, flare rear quarters, etc. What he does won't necessarily work on your car and it's not worth it to him to give them to you, then you spend a bunch of money on wheels and you're all pissed off when they don't fit your car.

You should buy a wheel fit device to make sure you have correct measurements for your car.

Huh????

What are you talking about? These are cast "spin forged" wheels. They offer them in set offsets with a few options and he already stated what the front offsets were.

I understand what you are saying when it comes to custom 3pc wheels but that does not apply here. Plus I wouldn't just order some random offsets. I would measure and setup for what I need and want. The look and setup I want may be different and we all have different setups as far as brakes, suspension, rearend widths and front subframe and spindle setups. I really don't know why you felt the need to speak for Mark. I'm sure he can speak for himself and if that is truly the way he feels in this particular case then I respect him for that.

I do agree with you on the part that everyone should measure for their wheel setup and not just go by something they read on a forum.

Not trying to start a fight but come on.

Read the last post on page 1.

Cool. So like I said earlier....these are cast wheels with 4-5 predetermined offsets and he stated what the front was. And also like I said earlier I would not expect or ask someone for the offsets they came up with on their set of custom forged or 3pc wheels. First of all because they would do me no good and 2nd because that person has gone through a good deal of work to come up with it. At the same time I don't get why people want to keep things like offsets or spacer setups a secret. I somewhat understand on full on custom modifications done to a car that someone came up with all on their own. But still in the end in this car enthusiast community we should try to help each other out where we can. Also people should not flat out copy original ideas someone else has come up with.

In the end wheel offsets and backspacing is not some black magic or voodoo. It does take some time and measuring and a little know how. Now the other stuff that Mark does with his cars is some sort of black magic. The ideas he comes up with and executes are just flat out amazing. And I can also understand what he is saying about a simple question snowballing or even worse when people ask a question about something and then when given the answer they are clueless as to what you are talking about because they have done zero research or have not even tried to educate themselves on the basics. But these are the things someone like himself is going to have to deal with unfortunately. Gotta take the good with the bad and when you are basically considered the godfather of pro touring it's inevitable.

Didn't think I was going to have to write a novel or that my post was going to turn into this. In the end like I said I can understand what you were saying to a point. All I was saying was that it didn't apply here and that you could have spent your time better elsewhere with that post or just left out about 90% of the post and still made the same point without coming off the way you did.

But no hard feelings. Take it easy.

or if you were a true godfather fan you would have every single page memorized. :buttkick:





36mm = 7.9173 in

My wheels are 18 X 10 with 20 mm offset front and 18 X12 with 36 mm offset rear. Forgestar will build custom offsets if they fit within their blanks. I have NO idea if they will fit your car......

Mine were custom made and the lead time was 8 weeks. FYI

Mark

36 millimeters is a little under an inch and a half. are you adding that to the 0 offset back
space to come up with 7.9173"?

from here http://www.mrw-wheels.com/wheel%20te...t%20chart.html
Im a United States public school grad too so I need all the help I can get.



Actually 36 Millimeters = 1.41732283 Inches, the 0 offset on a 12" wide wheel is 6.50in and 1.41732283 is 7.91732283

You scared me a bit cause I don't usually spread FUD unless its well deserved. :mock:

36 millimeters is a little under an inch and a half. Are you adding that to the 0 offset back
space to come up with 7.9173" ? Just for clarity.

0 offset is zero offset from center so that would be what ever measurement half the width of the wheel. The offset was 36mm (positive) so you add that to the center measurement of the wheel.

How did I come up with it? I just punched the numbers in the little boxes and it spits out the backspace inch equivalency. Its aliens.

Mark,

Where did you get such a screaming deal on those wheels? I need to know so I can keep my eyes peeled this Black Friday.

Thanks

Jesse

Holy cow guys cmon....25.4 mm to the inch....so 36 divided by 25.4 = 1.4173"....aka 1 27/64"
The whole world is on the metric system the proper conversions are very easy to find

There's an App for that.:secret: :underchair:

I was poking around last December looking of an "Economical" one piece wheel that would fit over a 394 mm ZR-1.

I saw Forgestars on a few cars and was checking them out. I called for info and I happen to call on the Black Friday sale. The normal price is still not bad but you get what you pay for. Finspeeds and Forgelines are works of art and these are OK for track wheels.

If I sell off enough used parts I will get a set of USA made mono blocks.

Mark

Thanks Mark, appreciate the time!

- Jesse

Thanks Mark I ordered a set for track wheels. With only 5mm I am glad I didn't just take others advice. Even Forgestar said standard fitment for ZR1 brakes are 18x10 +30 offset and 18x12 +50 offset which would hit the calipers.

thanks for the updates Mark. Your explanations of why you make the changes/modifications are great. It gives us insight to your way of thinking that can benefit all of us.

The wheels look great with the yellow on the car!

I think that POS needs a set of polished wheels.:lmao:

Just as always Mark,very impressive work to a already well built car:trophy-1302: :trophy-1302:

Are you planning a door like a gas door for access to the oil fill? Looking good as always, Mark.

I'm not sure if this is the one and only access to it, or if you had seen it a few pages back.

Thanks, Robert. I believe that's the lower access. I know Mark has said he was putting a door in one of the cars he has built. I just can't remember which one it was.

Will Thomson sell the ls7 (forged with oil squirted)upgraded short block by it self??

the removable lower is access to service the tank and get to the lines. there will be a fill port / dipstick through the firewall similar to how it was on hellfire

I'm sure he will. Give them a call Thomson Automotive / Lingenfelter 248-349-0044 Wixom, MI.

Mark

Thanks mark!!

Updates?
 

We need an update, had to go to page 4 to find this thread....

We have the 40 mm taller intercooler bricks and spacers in from C&R. We hope to dyno is in a couple weeks.

I had to purchase 4 sets to cover the tooling so if someone needs/wants a engine set IM me.

We wrapped up 90% of the wiring. I need to finish the ABS brake lines then we can repaint the engine bay and bottom of the car.

We finally have a solution for fuel flow. With a lot of help from Kinsler, Carl Casanova and Jason Hines we feel the best solution for E-85 and Gas for street and track is going with 2 CTS-V fuel pumps controled by Carl Casanova’s Vapor Worx system.

We need 2.2 gallons a minute at 65 psi at full power.

Because JA had a Ricks tank Matt is modifing the tank to allow two pumps and the in-tank pickups.

http://i439.photobucket.com/albums/q...ps8cmskjdy.jpg

Good choice! It'll prob look like this when done.

Very nice.

I guess pm'ing Carl is in order to see if that retrofit is doable/available for my Ricks tank, as i do get starvation issues on the road course at 1/2 tank....(hmm, maybe i'm not driving hard enough?)
