At what HP levels do lean rear cylinders start showing up at?

Or a Old style LS1 crossover.

Do you think 3AN lines are enough, or are you using 4 for your setups?
I know some places I can get the fittings to put one back on. I just hate pulling all the crap to get the intake off
I've been hoping to call and place an order with one of our sponsors for 3 days now, but every time I pick up the phone, someone comes in here and wants me to do something (<---at work, I hate dayshifts ).

Thanks for the link

Not sure if the 3an stuff would be better or not but we had issues with 7 & 8 last year even with the crossover.
Trying something different this year for coolant flow but we will still be using a LS1 crossover or the 3an lines, not sure which yet.

This says a lot.
How many people here have a tune they think is dialed in at the same level of ATV?
(Stalked a few of your posts here and on bullet ) And he still pulls ALL 8 plugs on EVERY pass. This just isnt something you can not do and hope for the best. This can save your motor and make you faster. No reason not too.

That $16 for the plugs is the cheapest protection you can get. It would be foolish to trash a $30k motor over a $16 set of plugs. At the level ATV is at $30 a run ain't much. You would be surprised what it takes to run that car at a race.

Thats all it does it help cool those rear cylinders off. If it can drop the water temp just a little bit that will help a great deal in helping keep those cylinder temps the same as the rest of the motor. I have -4 line on all mine going back to the radiator.

I don't deny that one bit, but it just seems to me I've never heard of forced induction guys pulling every plug after every run (perhaps I just haven't researched that enough though). I couldn't even imagine pulling plugs ONCE around some of the turbo manifolds I see on some members cars! At ~2.5# of n2o every run (anywhere from $2.50-$10/lb depending on location and availability) plus what could easily surmount to almost $100 in plugs per test-n-tune day, the cost effectiveness of nitrous over a forced induction setup seems like it drops off quickly.

I had read something in my searches about it not being all that great on automatic trannies to go from full throttle at the end of a run to just up and kill the flow/cooling to a transmission, which is what we do when killing it at the end of the run. It was a side topic in a thread about shifting into neutral at the end of the run (I guess a big no-no due to over-revving the drum) Any thoughts/feedback?
Also, with my current tire/gearing, I think for actual 1/4 mile time runs, I might have to use 4th (not 100% sure yet). Since I wouldn't be spraying in 4th, I cannot use the plugs from those runs for fine tuning, correct? Since the last second or so will be WOT N/A.

I have a 10x lighted magnifying glass I use to check them out. Cutting them may be the best but that would make them useless and its time consuming at the track between rounds. I really have no clue as to what I'm doing anyway which is why I'm still slow.

Yeah I don't believe anyone in this thread so far is slow lol
I'm still soaking all of this up. I got some addons ordered for my bottle and heater, B8EFS's, and ordered those coolant fittings from Kurt Urban Performance. I'm gonna pipe it up with 1/4" S.S. tubing. Hopefully that'll help those back two cylinders stay cool.
As soon as I get off this overtime stretch, I'm gonna get it all installed, grab some 110 for the standalone, and head for the nearest test-and-tune.
However if I have the same tranny issues I had back in 2006, it'll be another slow year
It'll be a serious buzzkill if I have to come up with another $600-900 for a professional re-tune.
