Are you guys dropping in some racing fuel for added boost?

Temperature and elevation have a lot to do with it. I'm close to sea level and usually go with temps below 60-70*F.

I have the FI exhaust and stillen G3s...passes with those MADE NO DIFFERENCE in my times. The uprev netted me 3/10ths (best run vs best run) in the 1/8th and 2+ mph but the shifts are MUCH harder and I now break loose on the upshifts. will keep trying.
all in all, this car is impressing me more and more. N/A 3.7 6 cyl capable of 12 second runs. BMW uses turbos, GM and Dodge 6.2 liters and the new 5.0 is just a beast.

They might not have made a difference in the 1/8th mile, but they probably would have in the 1/4 mile. Each of my bolt on mods made me a little bit faster in the 1/4 mile but more noticeably improved my trap speed. I've trapped as high as 109.5 mph and that's without Uprev.

Race fuel would slow the car down further, unless it was detonating madly.

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.

nmjaxx9 · 11-28-2012, 03:25 AM

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

I dunno the comparisons, but it may surprise you...

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.

Yea, what I mean by garbage is that it requires MORE fuel (this is what I've heard) and higher pressures to burn efficiently (kinda like lo grade diesel) and that we were duped by environmentalists into producing the stuff. 2 gallons of standard fuel required to produce a little more than 1 gallon of etho. remove the subsidies and only a few could afford to run it daily.
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.

I figured my 650 el played a part here in central tx, along with temps and humidity.. but still! I just cannot see how a full stock 370 without bolt on mods can achieve these times!

SharpByCoop · 12-14-2012, 07:09 PM

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!

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

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

Check the first post for the full list of times. Depending on the exact time you're anywhere from 7th to 10th.

if i remember correctly it was a 13.01 which makes me 7th on the modified list

Red__Zed · 12-14-2012, 07:39 PM

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

chuckd05 · 12-15-2012, 04:42 AM

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

Good luck.
