My Huummp...
My hump, my hump
I blew my rubber hump
I noticed methanol water mix on the underside of my hood.
The hood smelled of strawberry methanol flavor....
I have stainless steel methanol lines, so no leak there.
Boost has been down to 9 PSI lately.
I noticed a small nick in the rubber hump coupler, just enough to have a slight leak if it goes through. (it looks like it does)
I blew my rubber hump.
I am now going for a ride with paper napkin "diapers" on all my fittings and the hump...
Update 10:39 pm Thursday, May 21 2009:
Methanol leak, It was an AN fitting that was not tight.
The methanol "flavor" smell makes a leak really get noticed fast.
If you smell strawberry from under the hood.....
Boost coupler, yeah, the leak goes through, I am only getting 5 to 9 PSI now.
New coupler tomorrow from Murrays, I needed M5 anyway.

OD, You had mentioned earlier you were thinking of cutting your RPMs; any thoughts on a larger S/C crank pulley?
More boost would make you smile.
I have the 5 inch and really should not hold the engine at 10K redline, there is also a 4.75 inch that is a step up from the 4.5 "stocker".
I also went with larger "blue" secondary injectors from an automatic to richen it up for the extra boost at higher RPM.

with increased boost comes higher egt's--thats a little concern of mine since I track my car not infrequently and I am not sure if my egt's would get into a zone I don't want to be in. I am not sure if the w/m is lowering it enough on track. My exhaust collector gasket blew out my last track event and it was the Percy's seal for good aluminum one.
My plan is this:
1- I am going to do a little data collection per efi dude with my current set up as a baseline
2- add the larger air filter (this weekend) and do another run
3- added the new TB--another run
4- Then the big one---add my modified lower intake and do another run . This one will take a little time--not a simple job
After that I will see what I have (anticipated maf readings below 8K of 310-315 range)
I may have to go to the bigger injectors since i am so close to the 100% duty cycle now.
I do limit my rpm's. Gears 1-2-3 limit to 8K(comes so damn fast!)
4-5-6 to 7 to 7.5K --it is actually faster that way. No "faster" is a subjective term---its not black and white--but this is what I try to do.

My CAI plan, update 2:
I found a 90 degree 3.5 inch tube that is a little over 10 inches long each direction from the bend.
I bought two, one to go out and down, the other to go right and across.
I am hopeful they can be cut to fit.

Guys this 09 conversion is gona need to happen in stages. Its looking like I might put the Pettit intake on first, ive in the past used the intake and flipped the throttle body and added a maf housing to an adapter that bolted to the throttlebody. The reason is im trying to get this puppy ready for instal but I still need to reposition the OMPs that now stand in the way and still drive it.

Good to hear from ya Moon----! 09 install will be interesting.
Say--question--- what do you think of the yukon coils install and how can we get the optimum dwell times for them?
By the way --IF you road track your car--put an oil catch can on--you will need it. I need to rework the oil filler assembly some--more to follow.

Would the Sohn Adapter help?

well just did some efi dude data collection between the regular cone filter we all got? and then the bigger kn rf 1033 --little bigger--different shape.
from 58 to 81 mph it is 0.2 secs faster--really not statistically significant. load was different 150 with small filter and 147 with larger, maf readings actually lower with the bigger filter (3nd gear) 285 where with smaller filter it was 291.
me thinks the trims have to get used to the larger filter.

Hey ya !! idle comes back
Yo all ! 
So I founded a hose unplugged, see picture, the one with the yellow line.
hope it is correct.
So I now have an idle position.
look at those three videos to tell me what do you think; I found the idle sound strange.

when I gave a run, I had a CEL twice, I'll take my computer with me next time to see the code number !

About the hose I plugged, we tried to look every failure and we didn't found anything before we thought maybe we have to plug what you call the BARO.
As it wasunpluged, we said "Yeah we forgot that one !!" and it works...
tomorow I'll give it a run, if I get a CEL, I'll check with my computer the code... maybe I have to unplug that thing
What may help me is huge pict of your hoses connections...
can my problem comes from an insufisant air flow in the engine (filter) ?!

i dont know if he was kidding or not---on line-- you know you have to ask all --no matter what. No insults intended.
Dude if you have oil in the s.c. then your idler pulley is the only thing making that kind of noise--its really loud. look at the adjustment. you really need to fix it.
if you really didnt add oil to the s.c.--hey once i cranked up a car when i forgot to put the oil filter back on! add the oil man if you havent--please.
????
on another note yall like my cold air?

I use Royal Purple 20W-50 XPR, I was told to use 20W-50 in the supercharger by Cam.
I bought a quart of the Royal Purple in February of 2008 when I made the first oil change, I still have 1/4 of the quart.
Fill the supercharger to the indicated mark on the screw in dipstick, the oil level is measured by simply dropping the dipstick into the S/C dipstick hole and not by screwing it in.
