Ran at the Track Today
My wife and her parents went down to Perry, GA. yesterday for sight-seeing and in preparation for the 3-S track day at Silver Dollar Raceway today. According to all reports the weather was supposed to be incredible on Sunday, mid-70s, sunny, etc. Well when we got ready to leave the hotel at about 10:30 is was over-cast with a temp of 70 F and Dew Point of 69 F, figures! 
So we start driving to the track an on the way my SES light came on, Great, I didn't bring my laptop and I'm 2.5 hours from home. But the car was running fine so when I got to the track I pulled #13 fuse to reset it. Good news was that it never came back on until the drive home which I reset again but it hasn't come back. I expect it will appear again and will get the code then, more on that when I see it.
Temps when running were about 80, but the humidity was unknown. But considering how bad the knats were it couldn't be good. Add to this the 10 - 15 MPH wind coming out of the east with the track heading into the east and we had some crappy track conditions.
I met up with one of our GS friends, DrRick to get some friendly competition in. My father-in-law drive his SC430 so I was up against two Lexus's (or would that be Lexii...
). To add to the issues, since we came down on Saturday and spent the night along with local shopping my trunk was plenty full (my wife was with me remember). Add to that the need to keep the spare in the trunk and I wasn't running the slimmest weight vehicle. Except I was low on fuel which came back to bite me on the last run.
One more thing, I never finished my spring blocks. I got them cut but not drilled. I'll finish them soon enough...
Now that I have stated the less that ideal track and car conditions I'll go into the times. Which I was quite pleased with considering the circumstances and related to other cars. Plus, it wasn't crowded and I got ten runs in about 1.5 hours.
One point, no matter what I did I never ran a short time below 2.3. I tried every style launch possible and ended up with a best of a 2.304. My average was probably about a 2.35 with a worst of 2.592. Anything over just 1k revs and I lit it up. Yes, I am on the stock Michelins and ran 27 PSI up front and 44 PSI in the rear. I've got to work on the short time and once better I expect some great times!!
One launch had me spinning so bad and slamming the rev limiter that I hit second still spinning and again hitting the limiter which required 3rd. Needless to say that was not a good run. I just coasted on through for the rest of the 1320 ending with a 16.6@73....
Here is my best run of the day which was against my father-in-law:
Car 7(Me) 8(SC430)
RT 1.047 0.670
60’ 2.312 2.327
330 6.203 2.327
1/8 9.373 9.801
MPH 77.86 74.00
1000 12.073 12.653
¼ 14.368 15.045
MPH 98.26 94.81
So I won against an SC430. He did get the jump on me but I was able to run him down. These times were close to what we were getting. I ran numerous 14.4s with a best trap speed of 98.41. There were several other runs with traps in the low 98’s. My father-in-law ran many low 15’s with a best of 14.96 with all of his trap speeds in the mid to high 94’s. I would have assumed that he should have run in the 14.6 – 14.7 with traps in the 96 – 97 range.
Now on to my runs with DRRick in his GS400 with intake and exhaust; we ran about four times with me being victorious every time. In almost all runs he would get me off the line but I would catch him and pass. We were both very surprised how hard I was pulling up high. It seemed that once I hit 3rd I was easily gaining and passing him; that gearing of the 6-Speed helps out quite a bit. Rick ran in the 14.6’s with traps in the 96 range from what I recall. I honestly expected him to pull higher traps than me so maybe that polishing did help.
BTW Rick, it was great to meet you and I hope we can meet up again!!
The overall times were not that great but in central Georgia we never expect them to be. But comparatively I was quite pleased. Running 14.3’s@98 is fine with me especially with short times in the 2.3’s. Which brings me to my next track date; I’ll be heading to Atlanta Dragway in late October but by myself this time. The spare will be pulled along with nothing extra in the car and hopefully better air. 13’s are certainly within reach and how far into them will be determined.
Now I need to go find out what DTC is being set…
BTW, I have in videos of several runs including one in car shot which my wife took. Once I get those off of the camera I’ll post them.

I'm glad to see those nice 14.3's even under non-optimal conditions.
One thing that seems strange to me is that the gains in 1/4 mile times on the 6-speed do not seem to be affected all that much by the addition of headers and CAI.
It seems that the Headers and CAI cut more time from the auto cars than they do from the 6-speeders. I really thought a six speed with headers would be a shoe-in at 14-flat and better.

first off, i wanted to give props to scalbert. the man really put some work into his car and the times showed it. i had a blast. like he said, i would get a lead and hold it, until i hit 3rd and sure as shit he would walk right by. i guess its time for that 3.76 LSD. we def have to get together again. holla......
thanx, but no one is cool when they lose

Nice runs man, I would love to see those videos. So Scalbert you port and polish, how much did that cost you? That will certainly give you more power no doubt. I was going to do the samething but it was so expensive. Also what does a STOCK 6sp run, one tried to play with me but gave up pretty fast

Mattg is pulling a 14.3 with his less-modded auto CLS (he doesn't have a port/polished intake manifold), so really 14.3 is a little disappointing if you compare mods and expect the 6speed to lose less power to the wheels and all that.
It's still a great run though, as I said in my previous post.

What Frank said. I did the work myself so it cost me about $50 in catridge rolls. It took me about six to seven hours total including the removal of the parts and and re-install and this was over several evenings.
A stock 6-Speed would run mid to high 14's depending on conditions and location. I would have expected my previously stock vehicle would have been running very high 14's if not into the 15's yesterday considering what my father-in-law ran in his SC430 and Rick ran in his GS.
I make this relation in parallel to what I stated before. A stock 6-Speed and a stock GS would run about even with a modded 6-Speed pulling on a stock GS. Rick does have an intake and exhaust but I do have a little more than that done which is probably what helped me edge him out.

I normally try to compare with cars I run against that day to gauge performance. Plus. I doubt any records have ever fallen at Silver Dollar Raceway or Atlanta Dragway...
Would it help to know that a Z28 was running high 14's and a late 80's GT was in the mid 15's.
I agree, I would like to see better overall times myself. But you take what you can get at the time. Heck, maybe I'm just a crappy driver who can't get below a 2.3 short time!

Guys...
He ran with a passenger and a bunch of crap in his trunk and still pulled off a 14.3 - I think that's very creditable. Lightened up a bit, he's looking at 14.0 to 13.9 on street tires!!! Try to get your 60' times into the 2.0's and 2.1's, it translates to about 2-3 tenths off down the stretch!
I am doing some similar work to my manifold etc., will post when I finish it up.

Well just look at the gearing - with our 5speed we spend more time in the upper rpm range so we get more benefit from the headers at their peak. The 6speed is adding a shift and spending less time in the high end with the closer ratio.

It's still a great run though, as I said in my previous post.
If someone was to get it done by an outside source, it would most likely cost a couple hundred dollars. If it's extrude-hone'd, it'd be around $400, IIRC.

I guess the HP gains would be less than 10 WHP at best..... Have anyone saw a flow model for a cast manifold and port & polished Manifold... Does it improve the flow by more than couple %s...?
Just asking.

steve, buddy. you think you have the time and inclination to port and polish a V8. a "friend" of mine has this car that is looking for some top end HP. let me know so i can tell "him":P

Guys
Different days... different tracks... different weather - you can't
compare E.T's like this!! Add driving skills to that, and you have
many variables to contend with.
Port and Polish might help slightly... you need to bore out the throttle-body though - should be the first thing to do! I am having my TB and manifold work done next week, so I will update you folks on what happens.
I ran 14.1 @ 98 at Carlsbad... nice conditions. 60' was 2.09 something - stock tires. 1800K launch, 16-18psi up front and exhaust unbolted completely - no spare tire.
Mid 13's are realizable with a little more work and some better tires!

That's why.
i've run 14.302 @ 98.69 but that was with better conditions than Steve encountered.
Look, I'm not being a bitch, I'm just going by the numbers like all those lovely Mustang, Maxima, etc owners will when you try to tell them "take into account weather, humidity, and elevation" and they just go "duhhh but duh slip says 14.3 duhhhhh durrrr *drool*".
So like I said, I'm just saying...

I will be trying everything to get the short times in the 2.1 range which should hopefully net high 13's.
