Seafoam your engine.. What its worth?
Seafoam your engine.. What its worth? I'll let this thread go a day before sharing my results!
In short we just finished a heads cam package on my own personal 01 Z06 (terrible about oil consumption). It has since in the past 4 months loss about 20-25rwhp.

I've seen substantial gains from doing induction cleaning services on certain cars. Had a few that I couldnt get the timing to where I thought it needed to be without KR. Do an induction service and KR is gone.

The car made 490RWHP average last december. It had one good 494rwhp pass but most runs where 490rwhp.
Over the couple of months I would steadily pull timing out as knock started showing up. THe crazy thing is it was mostily one or two single pings instead of a fast rapping like most knock sounds like. It also would not show up on the scanner.
Some time in Feb the track wasn't open but some guys where practicing. Since we are next door I went over there and with no track prep the car with 2.0+ 60's went 97.5mph
4/9/2008. Get 37lbs injectors and retune it on the dyno. All it would give me is 480rwhp I'm down about 3-4 degrees over what I ran in december.
4/19/2008 We have our track day and I get 2 pretty good passes out of it. 60' is off but I'm not trying to kil the car.. 1.69 60' but heres the kicker.. it would not trap more than 96.. in fact the fastest trap speed was 95.96mph.
4/20/2008 I strap it to the dyno as the car was ran at the track.. Sure enough car is down big time.. instead of 490rwhp 430rwtq the car made 464rwhp and only 408ftlbs of torque.
I ran a half can of seafoam thru the intake and the car instantly picked up 9rwhp and the same in torque. This was hot too as I just burnt out the seafoam and then followed up with the run. I ended the day at 488rwhp 427rwtq which was pretty damn close to what the car did back in december.
SO in short.. simple seafoam on this car picked up 9rwhp while being able to tune it agressively with the cleaned upper end picked it up 24rwhp and about the same in torque
These results are not typical. Infact if this car didn't have a overactive PCV system we would have likely not seen any gain. Since most LSX's do breathe alot of oil it is definately something I would reccomend as a routine maintience type of thing

i just seafoamed my car a over the weekend at about 95k miles on it... i did the can in the fuel tank first and ran that thru, then i followed the write up on here... it didn't smoke to bad when it sat in my driveway, but after i pulled into the street and got on it, it looked like a house was on fire or something. insane.
results afterwards: no dyno comparison or track results, but it feels stronger, and its much smoother when i'm sitting idling at a light. plus it was a lot of fun.
i just gotta run my car 100ish miles and then change my oil, as i used it in there too.

99zman..
Take the vaccum hose off the brake booster of a vacuum line that goes to the manifold, and get a funnel, and start pouring slowly, the car will sound like it wants to choke out.. dont let it... just pour real slowly..
When you get to the last little bit, dump it in so the car does choke out.. and let sit for I think 30 mins.. then go have fun smoking people!
