Dang man you car sound sick. :thumbsup:

Hi Steve, just a query, at the beginning of this thread you said, QUOTE:-

"Bigger on the list was that David thought we needed more shock travel. Seems that were were on the stops durring hard turns and even on acceleration. We worked with Steve Duck over at RaceCar Dynamics and came up with a shock that's over two inches longer. The new Bilsteins are also revalved for the car. The extra length meant that we had to punch holes in the trunk floor so that this mount extender could be welded to the top of the existing brace. The top hole is for future changes if necessary."


Why are you still having trouble with the shocks bottoming out, I thought that this area had been addressed by "punching the holes in the trunk & welding in extenders"? Does this mean that you're changing from the Bilsteins to Penske shocks now? If so what's wrong with the Bilsteins? How much shock compression/travel are you getting with the set up as is? Could it be that your spring rate is wrong allowing an excessive amount of spring compression? Sorry for so many questions, but I'm sure that those people that are following this, wouldn't want to copy your set up & find it falls short of what they want, just as you have. :thumbsup:

thanks....Nige

If you are having
 

trouble getting in first without going to second...I believe you have a bad synchro.

Glad you car is back on the road.

Wow! That sound! Its intoxicating. :bow:

Going to listen again.

Because we keep softening up the springs to make the car more complian.. going from a 310 to 275 rear spring was just enought to cause the new problem.. I think the extra power makes the car want to squat down more as well.

normally we could dial in rebound or compression but my current shocks arnt adjustable.

Moral? get adjustable shocks if your going to do different types of performance events... just make sure you adjust them right

I will know more once Doug Nordin at GW takes a look and some measurements..

How much shock travel do you have available currently?

All of a sudden? Seemed fine back at optima.. then again it was acting up but we thought it was the bent clutch master rod...

Also has a hard time going into first if you are rolling more than 1MPH

not enough! lol

Seriously.. the distance (maybe 4 inches) is only part of the problem.. compression setting is another. with the old springs and power it was fine, barely, but the didnt crash out.

Thanks.. i love the new sound too

No shiat sherlock...:lol: I have 2" of compression available with 175's and the RR bottoms but the LR has about a .25 left. Clearly mine is under a full hook left hander. Man, you run stiff springs like the TCI car. No wonder mine rides like a Cadillac.:unibrow:

That was a good tease, I bet you can't wait for a real track!

Doug felt the if the car is this fast with these issues then it should be stupid fast once they are fixed.. even with me driving... lol

Do you mean ludicrous speed

Been having starting problems with the new engine and getting "cam sensor" error code

Worked with Scott Brown today on it and foumd that the connector was worn an not giving a cam position signal (so the computer just guesses)

Fixed that and was still getting a code... but it started more often

My LS2 is an early using an E40 computer.. as such its a 24x deal. When we built the 454 Comp accidentally sent us a newer single bolt cam. To get around this we used an LS3 cover and gear. I was focused on the 24x part that we didnt think of the 1x versus 4x cam sprocket deal.

Now mu com is looking for one pulse and getting 4.. So from a cam sensor perspective the computer is seeing 4000 rpm when the engine is ideling at 1000 rpm ... luckily the rev limiter and most functions read off of the crank sensor.. still, we think its hurting performance somehow. Just not sure how.

So, will the 1x cam srpocket even bolt to the single bolt cam? Can we "make" it work? I need to grab some parts and find out

The best fix would be to program the computer to recognize the 4x sprocket in the car.. dont know if that is possible.

Anyways, mystery solved an lesson learned.. make sure ALL of your parts match up.. lo

Looks to me that you could use the 3 bolt cam gear right on the single bolt cam - and then get your single pulse signal...

What I'm thinking is that if the pin is in the right place - or at least the same place on both gears (or perhaps you could drill a new one?) -- so that they're located correctly.... then weld up the 3 bolt holes - machine 'em flat - and ream/bore out the single hole to accept your single bolt...

Am I an idiot or what.... ?? :rofl:

No.. that makes sense. I tried my 1x gear on a 1-bolt cam ant it fits, but the reference hole is bit loose, not sure that matters that much.

I wouldn't think the three holes would need to be filled.. will know more when I compare all the parts.

When the single bolt cam surprised us I din't evem think of the 4x gear.. my brain just saw the half moon shape and rolled with it..

The loose hole could be BUSHED to make it fit correctly -- I wouldn't want it Sloppy - especially on a high revving single bolt...

The other solution my be to drill and tap the cam nose?

I was thinking the holes might be welded up because if you have to enlarge the center hole - you might end up with a real weak center area... wouldn't want that flying apart!

Funny about Comp Cams sending you the wrong thing --- I ordered a custom cam from them for my "rebuild" - and we ordered a harder billet for the cam - and they sent it without the pressed on distributor gear. That would make me have to run a bronze or composite gear on the distributor. Which I'm not doing on a street motor.

I bagged that cam and ordered a new one - same specs - but with the pressed on gear from CRANE - had that in two days.... and the motor is very very happy and so am I!

In there defense I'm not sure i specified.. Everything up until now has been three-bolt.. Like I said.. live and learn

The 4x cam deal is superior to the 1x .. just that my E40 isnt fond of it..

Drove the car 100 miles today.. what a blast :)

Steve,
Where did you hide the ECU?

Do you still need a gear? I can make another one. I was thinking about selling these things because it is becoming a big problem.

Up under the dash.. sort of behind the glove box.

You made a 1X single bolt gear? cool... Do you have a picture?

And yes, i would love to get one.. without it the consensus was that we would just leave it as is and live with it rather than do a cam swap

Greg, it is balanced.. the "bumps" one one side have corresponding "valleys" on the reverse..

I didn't take a pic of the last one I did. Here's what I do: mill off the 4x teeth from the gear you have now. Cut a .380" slice off some 4" .375" wall tubing. Weld the slice in the right spot with four rosettes. Bake until a toothpick inserted in the middle comes out dry. Takes me a couple hours...

Its not balanced, its stamped. The valley is the side effect. Other GM gears have the teeth with no valleys.

Why not just mill off the two "extra" nubs -- and weld a piece into the gap of the single bolt version -- thereby making the One signal generator...

It would then have to be balanced.. right now every "bump" has a corresponding "valley" on the reverse...

Really... hmm.. seems odd that it could be that much out of balance and ok...

If the balancing isnt a big deal it could easily be modified

Then I do the frosting??? :yum:

Why not just fill the area between the two large peaks and grind off the two small ones?

Hey, quit reading my mind!!!!!!!!!!!!!! :lol:

Sorry.....
:D

The bump would be in the wrong place. Its kind of adding 30 degrees here and grinding 60 degrees off there. I think its easier just to start over.

As far as the balancing goes, we spun a 1x and a 4x gear, they are both off. I don't think the weight of one tooth would make much difference compared to the harmonics of valvetrain.

cake ftw!

Since the 460 is now in process I've decided to just live with the 454 "issue" for now.

I also need to fix the first gear syncro in the trans, must have hurt it at Optima.

Car is still in Penske jail.. the engineer was called to England for an F1 deal.. for some reason they get preferential treatment. lol

So here's a random shot to hold you over...

Nice head lights!!! :yes: :thumbsup:

No sh*t :lol:

Penske Jail > Regular Jail

Can somebody show me where the car is in that photo?:unibrow:

Those are big...real big..........................toolboxes.:thumbsup:

Notice that Steve has been pretty quiet about that photo?

:_paranoid

On and off the track BadPenny gets it done :rofl:

Me likey...:yes:
