ARH makes nice headers but I wouldn't believe a word anyone that works there tells you.

100% irrelevant

you seem very sensitive about this. interesting.

kris, Evolvd is "A Member of Team Lethal Performance." he knows when something is scientifical. back to the lab again yo!!

yeah, that's what I said. don't forget to vote for bernie.

you guys should use a GPS speedo on the phone, I wouldn't trust your stock speedometer that high.

wait a minute, I am confused, I thought everyone says thermostat won't do anything?:headbonk: ;) Thanks for posting your results!

Looking forward to this piece....

If you aren't spending a lot of time at high RPM then to me the low (air) speed tradeoffs aren't worth it (and I have a JLT CAI). I think the stock intake is fine for a headers only car. If you go with all the bolt ons or a supercharger then an intake is going to show more value.

everyone except for you seemed to run higher temps with the 160 than the 170, myself included. there's a thread about it.

My recommendation is to start with a tune only and then decide if you want headers based on volume change, which I would try to experience in person and decide if you want to live with that every day. There is no volume control knob on headers or exhaust valve to open and close. If it's a...

"former nitrous industry" people.... why former?

I found a great setting for my Crusader drags at 4C / 1R but they still make noise.

correct. keep in mind, it's just a modifier, so it pulls 1 or 2 or 3 or 4 degrees depending on a load/rpm multiplier as well so it's not like you're losing 10 degrees or something. but a couple degrees can definitely have an effect.

200. if you are a visual learner I can post pics.

I think lambada is a dance.

You command fuel, spark, etc Then you check that against what you are actually getting Then you make adjustments to get them to match.

maybe this thread should be in french so it's more understandable.

Personally, I leave lambda the same for gasoline and ethanol no matter the mix. I run both right around .85 depending on the application, sometimes a little richer or leaner depending on the usage, head efficiency, cam, compression, etc. Some engines need more spark lead and richer fuel and...
