Kenny!
Hey this is Patrick, I am glad you are still autoxing that beast, the car looks wicked with the flares.
I need to bring my EF down to auto-x once it's running again, I'm sure you spank me though.. haha.

Update from yesterday:

I changed spark plugs (ngk brk7e11) because I still had some weird issues with the hesitatio n under load at the last autox.
Luckily I only had that issue in the pits.
And since I've already replaced the fuel pump and fuel filter, this is the only other thing I can think of besides the fpr.

I also checked and reset my valve lash to .007" tight.
Toda recommend s .2mm, and in hindsight I've got it a bit tighter than their recommend ation. I'm going to see how it feels and possibly re-dyno, along with compressi on and leakdown tests.

As for my oil burning issue, I found this quote by Endyn on Toda B-D Cams:

Quote
Valve problems can also be attribute d to valve springs failing to control valve motion. I won't build any engine with Toda cams these days because there are no springs we've ever found that will last any length of time with them. When the springs go soft, valvetrai n separatio n occurs and the valves typically end up being "dropped" on the seats, rather than eased to their seats by the closing ramps on the cams, thus pounding out the valves and seats.

The potential damage from weakened valve springs is that great in my opinion.. .at least with Todas. I also don't think their valve springs are up to the task either. If you (have) to run cams like those, you can't run springs that "fit" in an installed height that's relativel y "stock". You MUST run a spring that has at least 1.400" installed height with about 68-70 psi on the seat.

We also have a tool that we've built that allows us to machine the tops of the valve guides down in height to get some much-needed clearance between the bottom of the spring retainer and the top of the valve seal. This tool fits in a collet on the Serdi machine and it not only machines the top of the guide, but it also machines the sides and step so the seal will actually sit lower. On heads running in engines with cams with .485" or higher lift, we always machine the top of the guides to maintain .060" clearance between the retainer and the seal. If you don't, oil is forced (by the retainer) through the guide, contamina ting the mixture, and burning oil.


Well, I'm hoping my dart build will supersede this issue, but in the meantime it's a decent explanati on.

Next up, I'm tire shopping - hopefully I can figure out something before the next event on 4/3...

Well I've decided to go with Hoosier r6 compounds because they will last 100 runs as opposed to the 40 that the a6 compound gives you.

In the interim, I'm going to go with 225/45/15 in the front on 15x8 and 205/50/15 on 15x7.

I'm also going to take the ST rear swaybar back down to full soft, or maybe just medium.

Depending on how this performs, I may move the 225's to the rear and run 275's up front...

Ok, so I think my best was a 51.284.

I had the rear sway on full stiff, front dampers full stiff, rear dampers full soft, front psi at 34 and rear psi I kept dropping till about 32 or 30 to try and get more grip out of them. 225 r6 up front and 205 r6 rear.

They really didn't feel like they got hot enough to stick. And it didn't help that they are from 2005.....

The class leader ran a 48.xxx I believe, so I'm not closing in on him...

I may have to break down and get some rs-3's to see if I'm faster on new hankooks.

Points # 5 at turner field:

My best run was 51.397 which was 0.463 off the class leader.

This is the closest I've come to him all season.

I'm running these old r6 Hoosiers in 225 front and 205 rear.
ST rear swaybar is still on full stiff.
The front dampers are on full stiff and the rear dampers on full soft.

I think the hot weather really helped my times.

I may try some tire softener for the next event.

I'm pretty sure that if I had some better tires I could do better.

But the class leader is still on hankook rs3's!  :o
