Where were you? I didn't see you at the track this weekend:icon17:

Great times for you! NOW I'm cranky. :shakes head:

I had a BUNCH of work I had to complete last week and weekend (photography gig) and although I knew it would be a good outing at a track with these temps, I could not free myself up.

Where was my prompting... ;)

Race fuel = slower ignition. (Allows more timing advance or compression or boost. None of which you have.)

Best times = Good air (High barometric pressure), good traction, little incremental changes, and practice, practice, practice.

In any endeavor which I begin at (and suck at!), I always simply watch and ask and chip away at things. In time, all of a sudden you 'get it'.

Good luck!

Got a ??? for you. I've been seeing stations advertise No Ethanol gas. Everywhere I get mine, it's 10% eth or less. Knowing it takes more eth to make the same fire....has anyone compared "pure" fuel power to the corn blend garbage? Maybe I can pick up the last 1/10th I need.

gonna go back to Lebanon Valley when it opens again with some 305s I should be putting down better numbers than last spring. :stirthepot::tup:

The Corn Blend 'garbage' is actually e10, a step closer to e85. That's all measured in percentages.

For a turbo kit the 10% ethanol is like adding an octane booster. We can produce MUCH more power with 93oct + 10% ethanol than, say, CA at only 91 Hi-oct no eth.

Of course tuning is what is necessary to take advantage of the octane levels, and that's what I've had done.

YMMV.

back to original question tho....anyone run pure gas only vs etho blend and see any difference or is the fuel delivery system set up more toward etho?

BTW, got one of them new iphone thingies (welcome to the 21st century) and I'll be able to post my slips when I get home.

Well, on Wed I learned Jimmy was renting the track Fri Dec 14 at Atco. Hmmmmm.

I just returned for a lonnnng drive there and back. Worth every mile.

Five runs: 11.39, 11.54, 11.13, 11.36, 11.13.

That's right: TWO 11.13's within an hour. All around 122-123mph.

Here's the first proof:

I have videos from within and from the outside. Conditions could NOT have been better for me. Cool crisp 50° air, good traction and having both Jimmy and his lead tech Kenny; watching, observing, making recommendations and supporting me. They told me what to do and I delivered.

(STAND on the throttle and then leave. Build up the boost! Don't short shift. Run it to 8000 rpm.) Best 60' times Ive ever had. Three times in the 1.6's. 17.5 lbs boost. 93 oct pump gas only.

Anyway, I'll compile the vids over the weekend. I lost a day at work, so tomorrow I'll be too busy.

Once we did the FIRST 11.13, they did what they could to see if we could knock 14 hundredths of of that, but it was already maxed with this combo. I know what it will take to go tens, when the time comes. Gears and a different torque converter.

VQ's making it happen! :tup:

Congratulation.
Unbelievable times/60', especially with the extra weight. Got to try a cool night this Spring. Are they open tomorrow? Next week?

Nice runs coop! You're knocking on the door of 10s

Finally some decent times but get to 10s!!!

Good luck.

Awesome times! That is a killer 60' time also.

great times. do you have a bar in your car , or are they letting you run with out one ?

YOu can get away with much more on a private rented track day. There were at least four GTR's in the low nines. None of them had chutes, and some not even roll cages.

That's why they go on those days. Pay your $200 and have at it.

Running on Bridgestone RE-11 305/30/19

My first three runs where 3.38, 3.37 and 3.38. Running 25psi Those where the best, after that I tried adjusting by lowering tire pressure to see if I could get sub .2 60' times, but they just got worse and I forgot to bring the air pump. Went a couple of times at 22psi, and my 60' where 2.3/2.4 had horrible wheel hop and worst times (13.6/13.8), seems these tires like more air.

Track temperature was around 75F, I'm still not pleased with my trapping speed, fully bolted and tuned, removed (Spare tire, jack, etc..)

There was one run where i trapped higher 13.38@ 105.31, 60' 2.16.
what you guys think??

You've moved up to #16 :tup:

Congrats coop nice time really good 60 foot your car is getting off the line good . It will be interesting to see how your car does with a better torque converter, your moving through the 1/8 mile 99 mph top end its dying some .

You will be the first I have ever heard of going with 4.08 gears in any g or z that's turbo that's really short good job:tup:

I will join you in the spring at the track for some friendly competition
