Changes from the last track day include... lowering the stance slightly... and installing the new Global West Cat 5 leaf springs with the spherical bearing mounts. I loved the new leafs... this was a major improvement.The car did not squat when accelerating... hooked up better on the corners... and the car felt much more stable on the long high speed sweeping corner at PIR. No more bouncing at high speed.

For this event I kept the Fox shocks on the car. I wanted to see how the Fox shocks would work when paired up with the new GW leafs. I have to eat crow now on what I said about not liking the Fox shocks. The combination of the Fox shocks with the GW Cat 5 springs worked great. No more bouncing on the back straight at high speed... the car felt very stable and handled great with this combo. I am learning as I go... and finding out that the suspension set up is very complicated. The Fox shocks worked great with the heavier leafs... and Iwill not be changing back to the Bilsteins.

Here is the video... the time for the last lap (after passing the blue BMW) was 1 min 31 sec. The speed for that lap was 130 mph on the front straight and 128 mph on the back straight. I was chasing a Z06 Corvette through some traffic at the start... very fun day!

Awesome Dale!! 3 seconds is huge!! :thumbsup:

Love watching your videos Dale. I bet you keep getting faster too. :)

Would be great if a bunch of Norcal and PNW guys could get together at a track sometime (who needs those Socal guys?!) :action-smiley-027:

Thanks Gaetano! The car felt pretty dialed in out there on Friday. Now I just need to step it up and push it a bit harder each time out.
:cheers:

Thanks Dave... that would be great to have a Lat-G track day somewhere in Norcal I would love to see your car and the other guys on here (Socal :action-smiley-027: ). Count me in for sure. It looks like your car is getting close... I would sure like to hear your new engine out on the track!

:lateral:

Enjoyed reading about the continued improvements Dale. :thumbsup:

And giving us track vids to watch is very wise. :D

Love your write-up! :thumbsup:

Can you explain how you got full throttle out of the stock linkage?
Thanks

I used the original 69 Camaro mechanical throttle pedal linkage... then modified the arm that is on the engine side of the firewall. I fabricated an extension so the length of the arm is about 9 inches... this gave me enough travel to go from idle to wide open throttle using the second hole on the lever arm on the FAST TB.

The throttle has a good feel and does not come on to quickly. I wanted to make sure I had lots of travel so it would be easier to control the car when rolling the throttle on.

Here are some pics of the mods on the lever arm. The arm measures about 9 inches from the pivot point on the firewall, to the pivot point on the connecting link.

I made the lever arm just long enough to get the full range of travel on the TB. This worked out good... and the throttle has a good feel (not to fast... not to slow). I made sure I had plenty of clearance through the whole range of travel so the arm would never get hung up and get stuck.

Thanks for posting that Dale :thumbsup:

Kinda funny how we continue to work on the same things Dale. I had to do that exact thing with my mechanical linkage also. My lever at the firewall had to be extended by about 4 inches and shifted to miss hitting the fuel rail and fitting at the end of the rail, and the linkage rod has custom bend in it also. LS or BBC, doesn't matter. :)

I also just finished my cold air intake which is similar to yours, except I used a 17" aluminum cake pan. My filter doesn't sit quite as high as yours(maybe 3/4" lower), so I'm able to run an aluminum "bubble" top that promotes air flow instead of the filter top. My plan is to do 2 runs on the chassis dyno with the cold air unit in place and 2 runs with just a standard filter base just to compare. I'll let you know what the difference is.

That's a great idea to test the two set ups... I would like to know the results. I wonder what the difference would be between the "bubble" top, versus a filter top? I have run just a plain drop base air filter taking in the air under the hood.... and the same air filter set up drawing air in through the cowl hood. The engine seems to run a bit better with the cowl induction set up.... so I'm sticking with that.

Be sure to post up some pictures of your cold air intake set up... I'd like to see what you came up with.

It's fun to do all the little detail stuff after all the hard works done!
