Maybe I'll find some more power around 33 or 34 degrees, or maybe if I try around 38 degrees something magical will happen. I'm going to try those next week.

But like I said I can't afford the dyno right now.
How are you timing this beeeotch? Do you disconnect the reference wire and set per spec? Are you seeing the maximum advance via scans? And, it that the target advance? Prove what you are ACTUALLY getting for advance. Prove SOMETHING!

That USUALLY works better than holding an envelope to OUR heads and asking us to ascertain the answer to a question sealed in that envelope and placed INSIDE a mayonnaise jar under Funk & Wagnall's front porch -- since 8AM this morning.

You must use the Magic Diagnostics tool.

I'm timing it by disconnecting the EST wire, setting timing, plugging it back in, turning the car off, and disconnecting the computer for 10 seconds.

No I'm not seeing advance on a scan tool because the 870 ECU does not record spark advance or knock counts and knock retard.

Regarding your timing, did you make sure your balancer hasn't slipped?

Hold on now..........

after all of this $$$ dumped into the car, did you say $10K or something along those lines, understanding some of that did not go to performance parts, but my point being.........

You just bought a Corvette, dumped $6K into performance parts and another $4K or whatever the numbers are in miscellaneous parts and now you cannot AFFORD to get the car on the dyno to find out the vital statistics to dial it all in??????????????????

Do I have this right or correct me?????????


You have posts where you went after AFR because you thought they had issues which was amazing in itself, arguing with others on here who are VERY knowledgeable and been around a lot longer than you; you have been chasing problems for the last several months throwing $ at parts you don't even know if you need, and now you CANNOT AFFORD A DYNO TUNE??? I thought you said you had an appointment?? Did you cancel?? Were you being honest with us????

You can call me names too, but I think you answered your own question to this thread..........

What's holding ME BACK??.............. Well, I know where to look but you won't like the answer.......

The truth is that you are afraid of the dyno. You are trying to tweak the car so that you can get it to a point where you can make up some guess at HP and brag about it, and if you put that car on the dyno and pull a 188 after having spent your life savings on it you will not be able to sleep at night. Better to live in Fantasyland.

Insulting the senior members who have been doing this far long than you isn't a good way to continue getting their help, neither is arguing with them about their answers. If you already knew your answers why ask? You would already have the fastest car $10k can build.

It would appear others are starting to catch on to you being a troll.

If you truly want to find out if your car is giving its full potential or not put it on a dyno, or the track. Quit shooting for that 12.8 AFR and let the car tell you what it wants. The best performance is rarely gotten at a perfect 12.8 AFR.

And even if you really can't afford the dyno (like $50 or so?) you could go out and test it at the quarter-mile. Even that would tell you if you have made any more power than stock motor.

Dan on a new post you responded to a question about what heads to use. Now this hit me so wrong you give a person looking for help about what heads ect to use when at this point and time you are complaing about not getting the hp you expected. You tell this guy what to use yet you are saying on here that it did not work. Please before you give anyone advice make sure it will work and you know what you are talking about. There would be no way I would give advise on what to use and in another place be upset that it is not working for you. You have done this on a few different post I almost said somthing before but did not. Not trying to bust you to bad just want you to think a little. Now seriously you need to man up a tell a few people you are sorry.You need to work on getting some respect back if you want some honest help on here. Stop the fire on the burning bridges and make a mends.

Here's what has happened so far. I've been working with my tuner, and after going back and forth between new tunes and old tunes, and modifying my AFRs at WOT at the high RPMs, I am now starting to think that my fuel pump may not be able to keep up. Because it gets lean above 5000 RPMs.

Also, I need a new battery because it can no longer hold a charge, I blew my shift shaft inside the transmission which cost me $150 to repair which also included a new input shaft bearing. While the trans was out, I was going to replace a gasket on the overdrive unit, and I should have followed the directions from All Data first because the center drum popped out, an I tried to retract it from the back using 3 bolts as mentioned in All Data, but I was supposed to do that before removing the cover. Anyway, I cracked the pressure plate in the overdrive, so now I'm working on getting a new one and I imagine that will be $100-$150.

Also, I still have to fix my A/C compressor, and I'm planning on purchasing a conversion kit from Ecklers to go to R134a which also includes the compressor, because I am definitely not riding around in this hot weather in that car with no A/C.

Now, here's where we think my problem lies. I spoke with Ed Wright about my situation, in which the first thing that he told me was that I'm getting blow by because I put all these parts on a stock motor. Not enough blow by to cause the engine to use oil or not run properly, but blow by that will significantly affect horsepower on a motor that is geared towards racing.

To add to that, I had noticed, when I had my overheating issue, that at high RPM, smoke would pour out of the breather filter that I installed, and there was no oil loss. If it was smoke from the oil coming out, the oil would be evaporating and disappearing.

Also a small amount of smoke was coming from the holes in the head that comes from the lifter valley when I was adjusting the valves at idle.

So my next step is to finish tuning, then put it on a dyno, and then build a 383 stroker this winter. If I can make enough money by then.

OMG---I just ran upon this thread-----Tom, you are correct, this dude is Hanna Montana, if not then his twin. I have not laughed as much as this since I can't remember when. After reading the threads, this guy a great dancer, dancing around all of the recommendations given him. BTW--Tom is as good as it comes to diagnostic on these cars. I cant tell you how many times he has helped me. And by the way, I Have known Tom personally for many years, and he is one of the best people I know. You need help, Tom is there....
I regress, DanielRicany I believe has been on this forum with many different names. He got into a major peeing contest with a dearly departed friend Jim -CFI-EFI over the infamous Renegade intake... Tom and Jim were also very good friends.... This thread has all of the trappings of "84L83/85L98" ....This fellow is never going to a dyno, he will never post his dyno runs, or a 1/4 mile time slip, EVER....EVER!! If he is "84L83/85L98" then he is the worlds biggest TROLL....This thread will go on and on with his nonsense. If I am wrong, then here is an early apology, but I doubt if I am....

This is the only account that I have on this forum. And you will see dyno results as soon as I can afford to go to the dyno. My only source of income right now is side jobs, and there's not a lot going on right now which is why it takes so long for me to accumulate money.

Good luck finding your gremlins. $10k is a bunch of dough no matter how you slice it. I have less than that in my car for my mods and I would expect to make double your hp....
