Thread: Getting rid of KR?

Maybe your problem is that your cars are just SOOO fast and you have been doing this so long you have forgotten what it was like on a bolt on car....

Headers suck. They suck for flowing better... They suck for looking better... They suck for making it easier to change plugs.... they suck for allowing more timing... Yep.. they suck.

Yet, you have no proof of anything you say. Whereas, I've had many 3800 cars...with and without headers.

Well.. If you want hard proof from me.. why dont you provide some that says I am wrong???

Ok. Kr and boost on my 01 did not decrease when I installed headers on it.

How's that?

well that is not proof enough since I gave you similar proof and you invalidated it.

You need to fix your sarcasm detector.

No I picked up on it.. I was just giving you the benefit of the doubt that you would be an adult about it...

Yup.

this thread was informative

Yeah.....sounds like I have no experience. DH must not either.

I'm really getting a lot out of this conversation here.

So really, what's the best place to start to get my KR down? I don't have any Vac leaks. I'll get my exhaust leak fixed here soon. Should I give new plugs a try?

I have been doing this 3800 "thing" long enough to say what I say with knowledge and experience behind it.

Now... Let's keep in mind, I spoke about what you said, not about you other than to say I RESPECTFULLY disagreed. For your information I started driving over 35 years ago Internet smart guy! My first car was a 73' Pontiac Grand Am that I bought used, worked the engine, cammed and more and raced it too. Whatever... I've been out of the game for a long time, way before everything was controlled by a damned PCM, lol...

Eight years ago, lol... Doesn't mean anything to me, nor does any mumbo jumbo about your experience, I've already allowed for that. Simple formular is... More air in = more air out! Thank you very much...

hmmmm... All exhaust systems I'm aware of bolt on... Not sure what you mean by that? Bolt on Mod? Where is AROUND HERE exactly? I installed my Pacesetters and was not half the horror made out to be here online, no leaks either. Only problems I've had we're introduced by my thick head. Other than that, I've not known headers installed correctly to require any maintenance.

Fact is... Most of us who decide to mod, or start pushing these engines past the STOCK set up, get the bug. Many start small, then mod more, then even more and finally trying to squeeze every drop of speed or HP, go all out. I always suggest headers as it eliminates one of those steps early on. And quite frankly, only those who get the cheap headers fit the mold of what you say. There are some who follow smart exhaust doctrine with headers, meaning primary sizing, material (S/S or Ceramic) for proper heat retention, etc., which clearly is an advantage over the stock system, the back pressure b/s has been well discussed so not even worth it here. These 3800 engines are well known that the STOCK exhaust is very restrictive and just a bad design...

Bottom line is I will stick to my guns here as I've never seen a serious race car, street or track without them(headers), regardless of engine, platform...

Nuff said!

Lots of funny in that post.

Apologies for the divergent direction the thread took. It happens from time to time when people respond to others posts rather than to the OP question instead of offering their own solution to the problem, they attempt to address others opinions and experiences which is unfortunate.

As I have stated but ultimately you will need to do a little research on your own to try and make your own best educated decision... Flow mods will HELP address KR. Porting and polishing intake (s/c, tb) will help. Same for the exhaust which could be accomplished in a number of ways. Easiest would be to replace the stock exhaust manifold, IMO with headers. Some do just the Plog and some as noted do nothing. You could do even more It just depends on what you want from the engine and where you plan to take it. Daily driver or track car? It does make a difference... Pulley drops or stock? Cam? You could Intercooler and tune as well... Etc., etc. As for tuning... Adjusting fuel trims and timing can help eliminate KR too. If these all fail, yeah sure, mechanically you have issues. But those issues will reveal themselves prior to even going to these lengths. then commit to what ever it is you want to do and don't second guess. It's all good!
