slower then I expected

[LETZRIDE]

well I finally got out to the track with the new heads...no where near what I expected, but I was having a bunch of problems.

Best run of the day beats my previous best by .01 of a second...whooohoo:(

60'... 1.882
330'... 5.623
1/8... 8.785
MPH... 77.85
1000... 11.535
1/4... 13.864
MPH... 96.95

on the bright side, since I wasnt planning on going to the track, I had almost 3/4 full gas tank.

But the worst part, is I also had knock throughout the entire runs...about 3 degrees of it. not sure from what, or why...my fueling is fine. If anyone wants to take a look at the scans, I can send em to ya....kinda bummed out lol.

Re: slower then I expected

what would 8-10 degrees of timing do for me? Im thinking that makes a big difference no?

Re: slower then I expected

I would think you would still be running 26-28 degrees timing without any Kr. You can send them to me if you want ss6532@aol.com

Re: slower then I expected

I still can run 28 degrees of timing with my cam , heads/ intakes soon to be added, but I do have my KR sensors desenitized 40% for the past 6 years since theres alot of false kR on the 3800's. If it does pick up KR then I know its real, but still not audilble.

That's still awesome in my book. Perhaps some more tuning, esp. with those heads and you'll see a big difference.

I'll send you them when I get home...I was mostly running 20-21* with it beginning to climb back to 24* as I began pulling timing in an effort to fight the knock.

13.8 isn't bad...its just I ran 13.8 with just the cam...I want to see an improvement with the heads....

Knock sensors suck. Can you tune around them? I've never seen a single instance where someone said "whew, good thing I had those knock sensors, they saved my engine". They seem to be more hassle than good.

You can have them pull less timing per event and add the timing back quicker.

Re: slower then I expected

you can tune around them...but its a safety...I kinda dont want to bypass a safety for the engine...I can have it pull less timeing and decay quicker like brian said...but I would rather just not have knock, that way the retard doesnt have to kick in lol

The guy at the machine shop said with the right cam with intake and exhaust the heads should be a big improvement. I'm pickiing mine up tomorrow, which I think have the same valve size as yours. Hes done GN's, imports and what not but mostly V8's so he knows his stuff. Doing full engine builds, blocks , and all machining and is one of the best shops in AZ. Just send it when you can, are you running bigger injectors?

I would recommend just desentizing them where they go into the PCM like I did , best thing ever and it will still show KR on Hptuners before its even audible. Mines never gotten to the point where it is audible though.

Re: slower then I expected

how do you desensitize them?

Re: slower then I expected

Dude thats rediculous. Come on now. Don't make me have to come drive it and show you whats up.

On a serious note. I think with it tuned a lil' better it will be faster.

Re: slower then I expected

I think you should hook the maf back up and run it normal and see if there is any difference/ and if so how much? I think with your mods and tunning you should be able to get a low 13 if the DA is right, wouldn't be the first one to do it.
