This is without the chip (running a FACTORY STOCK CHIP) it was running real good in some parts of the powerband, but stumbling in others....

13.4 ET
110 Trap speed

My trap speed went way up, but my ET is only .3 better

I hope the Trap speed indicates that the project wasa success, and once the tune is right that it will produce acceptable ET's.

What do you guys think? My previous best Trap speed was 101.7, quite a jump huh? Should I worry about the ET right now?? Or just wait for the chip?

Ski, how much do you think that chip could potentially help?

Thanks!

 

TTT

Anyone can help with this??

Ski, Scorp? Ralph??All the smart guys please give me your thoughts.

Thanks

 

110!?!?!? Was that at a track? That already beats what mine has done! :D

 

I guessed at your cars weight at 3300 lbs. race weight. And with that, 110 mph puts you at about 340 HP to the ground. That sounds pretty decent for a stock displacement small block chevy.

That was with my GTech on a long road. The G-Tech is deadly accurate.

 

A G-Tech will normally show a few MPH too high since it takes an instant MPH reading and not an average over the last few feet like the tracks do. Still dounds like you're around 106-107 as a starting point which is excellent.

 

I found that the GTech was dead on for me, as before my project I was doing 13.7/101 at the track, and with the GTech. The GTech did give me a few 102-3, but rarely. I may give it a few more runs just to see what it averages out to. Also, it was very early this morning, car was about 160 degrees, and outside air temp was about 58-60, so it was ideal. The car stumbled several times, but pulled hard in points of the powerband. I think it is doing at least 108 also. So how does that seem to you guys as far as performance with the stock chip?? Pretty good or not? Should I worry that the ET sucked? I hope when that chip gets here tomorrow it makes a big difference! If it didnt look so good I would be ditching it in the canal with that putrid ET!!!

 

Not at all. I was turning 109.xx through the traps and only managing high 12s. It is all in the launch and the tune. :yesnod:

 

At those speeds the G-Tech values are likely about 1.5-2mph higher than time slip data. That's based on a 60' separation between trap speed timer lights and my velocity profile from Drag2000 software.

That would put you at about 100mph then and about 108mph now for drag stip values, which amounts to about an 80hp (crank) gain.

With a 108mph trap speed your ET potential is around 12.6sec!

It sounds like you need to hook it up a lot better.

Does your G-Tech show 60' times and acceleration?

 

Gtech shows 0-60 mph, but not the 60 ft time. The car hooked up pretty good, I estimate at least a 2 if not better.

From what I have heard, the GTech is more accurate, but the dragstrip is everyones standard. I am just using my GTech as my new standard for measurement since my nearest track is over an hour away and has huge waits every night that it is open. Not worth the trip!

I want to get a low 12 out of this car

 

Gus,

110 at a track would be right on Par for the setup. The chip should help with the stumbles and make things smoother.

My car, due to the rings leaking like a strainers, the best MPH I could get was 105MPH at 12.80 sec. Scorp was turning better MPH, but slightly less ETs if I recall with no tuning, so I think the times I was getting was greatly in part to the tune. You should be damn close with the chip.

As for the Gtech, I never had much luck with it, but you may have a better setup than I have.

Did you make sure you don't have any vacuum leaks? Without a scanner its gonna be tough to know for sure, so the ether will let you know. Just test it on a small area, don't want it hurting the shine :D I used it on mine with no fading etc.

One last thing for the chip I sent you. Make sure the base timing is at 6*...no more no less. Email me tomorrow when I get out of the woods I will check my mail! :cheers:

 

I will check for leaks, but we dont think it has any. Can you give me the details of the changes you made regarding the fan temp, egr, AIR, and TC? I hope you removed the codes for EGR and AIR, because they are both blocked off and I have codes. Also what is the Rev limit set at?

I did set the timing to exactly 6 degrees.
Oh, do you change the idle when you tune for the 219?

Tomorrow I am going to the muffler shop to have a resonator installed where my test pipe is. It is just too loud and has too much resonance without any catalytics in there.

Hey Jesse, I hope youre not going to shoot Bambi.....just shoot some dumb birds or Turkeys, not those poor deer!

 

:yesnod: :yesnod: You would not want to come in my house, Corky was here...you have all kinds of creatures staring at ya. :lol: :lol:

See it gives the kids something to play on....this was my little one when he was ~ 4 months old. Its funny he sometimes goes over and lays next to this bear and sleeps now that he is older. Must think its his buddy. He also tries to give it his binki and bottle:lol:

Poor bear, I wouldnt be able to shoot him unless he was going to attack me, but that would be unlikely here in Miami!

I have some info to send you in email.

I was not getting full throttle during the entire run, it seems the SR has caused some binding on the TV cable and its affecting the accelerator, it doesnt always quite reach full throttle.

The sound with this chip is totally unbearable- I cant hear myself think, it sounds like a Hotrod with open exhaust- I have to go to the muffler shop first thing!

Also, I cant figure out why the AC wont remember its settings. It just completely resets each time I shut down, and comes on whenever I start up, but without the previous settings....?????Any Ideas anyone?

 

Okay, getting rid of the resonance was not that easy, I first installed a long 18 inch resonator in place of the test pipe where the cat was. It hardly made a difference at all, I was not going home with this loud car! We installed a baffle plate inside the inner outlet of each muffler, it blocked about 65% of the pipe. Now it sounds great! I can drive my car again. BTW, we checked all the hangers, the tips were beyond the rear bumper, and everything was in nice and tight. Its just the dual outlet high-flow mufflers are miserable!

Now as far as the chip, it made a huge difference, even more so than when Craig Marcho burned my other one. Its not that Craigs was bad, but its that the more mods and HP your car has, the more effective the chip is. When my car was stock, I foolishly paid $300 for a TPIS stage 2 chip, and all it did was lower the fan temps. Craigs first attempt, with the data I provided him, made a big improvement, and he did a great job, but I had some mods at this point, so the chip work was very noticeable.

Now, I provided Jesse (Ski_Down_it) with loads of data, and a complete list of all my mods. Although the car ran surprisingly well with the factory chip, it was hard to tune the idle, and it would stumble in parts of the powerband.

The second I put in the new chip, the idle was easy to tune, the car responded better, and the trap speed and ET were much improved. I would think that this chip is better than anything you can buy off the shelf, its possible that Ed Wright may be able to do the same if you give him the data, but at a much higher price. Jesse is further analyzing more data as I send it to him, and he will make the tune even better!!! I am very pleased. His work has been worth every penny, and then some. If anyone needs a reference, please contact me. I wil continue to post results as we make improvements, but if you have mods, and are thinking about getting a chip.......call Jesse first. But dont think a chip is going to do anything for your stock car!

 

Gus-

That mph is excellent. Good for mid 12's if you have the right gear and good traction. What were your 60 foot times? That makes all the difference in the world. Congratulations!

 

The difference between 100 and 108 mph is not 80hp! The 10 hp per mph is inaccurate estimation (I sware advertiser use this method sometimes), for the weigh of our cars it is only true around 110mph, at 105 mph it take less hp to gain 1mph and 115 it take more than 10hp to gain a mph.

 

My local track is about two hours away and even more during rush hour all that to get 4-6 runs is what I am used to (and I always get their before it open as to maximize my number of runs)

 

Well our track promoters must be clowns, 4-6 runs would be great, its a good night if you get 4-5 runs and thats before 11:30 and then 2 hours back home and to work the next morning......and if you break!!!!?@#%^$*$()%%#@!

FORGET IT!!!!
