so what total rainbow of colors are you ending up with?
Has anyone that doesnt have the upgraded pulley changed injectors?

nope Im saving the injectors for the Pulley, first must install my W/M,,,

 

Anyway, I have two 2004-2008 reds for the P1 position, two 2009 greens for the P2 position and two 2009 browns for the Auxiliary Port position. You can change the four 2004-2008 yellow injectors for four 2009 green injectors while keeping the current flash or add the bigger pulley along with the combination mentioned above and still keeping the same flash while adding 35+ whp.

 

Do you plan on coordinating a new flash with Pettit(Cam and Dian) for the new pulley and injetors???

 

Nope. Did you see my last log post? Also, check this thread link and observe the A/F ratio gauge. https://www.rx8club.com/showpost.php...&postcount=103 Yes, is out of focus but still readable. I’m happy with the way the car runs right now and don’t feel like messing with it.

 

sounds like plug and play ----with water meth
you still running the 100 and 60 sizes?

BTW,

I think I'm getting better fuel mileage with the new 2009 injectors. I need to verify and will let ya'll know later.

 

ok so what is the down side to the new pulley set up---get the new injectors---thats all?
how would the s.c hold up on a road course with the increase rpmsi
olddragger

 

Yes, that’s it. Upgraded pulley and a pair of 2009 P1/P2 injectors (same flash). I have over 1.5k with the current setup to include a couple of autoX and two trips to the drag strip. Also, one dyno day, cruising at 80+ mph on the interstate and one trip to 141 mph. I also checked the fuel pressure once for over 35 miles under different driving conditions and the OEM fuel pump was able to keep up with the increase in fuel demand. Sorry but no road courses under my belt, yet.

 

OD - if ou are worring about over revving , just shift earlier

 

Watch you fuel pressure if you do the road course thing....there is a well documented problem in high G corners.....

It is good that you can watch fuel pressures...that will save you a lot of grief

 

2009 fuel pump---MUCH BETTER
OD

 

is it a straight swap to use the 2009 fuel pump?

 

no --but it is fairly simple to do--i have a thread somewhere......
but you have to modify the connector plug a little, the venturi line has to be cut and just clamped on and the entire assembly has to be rotated to a 3 o clock position(forward facing arrow) and thats it. so many improvements in the 2009 pump.
Just do it huh? Thinking.

OD/Rotr8

I placed a piece of rubber between the BeatRush transmission brace and the two lower transmission bolts (were the two pieces meet) and it cut down vibration/noise transfer considerably. I took a universal fit radiator hose I had laying around and cut one end (flat surface) and later trimmed the piece to fit between the two metal surfaces. I drilled two holes in order to fit the two transmission bolts and to keep the rubber piece from sliding away. I coated the rubber piece with urethane grease (the real sticky stuff that comes with urethane bushings) so I will not fade away nor will degrade the rubber hose piece. Support the transmission while removing the two lower bolts and torque to 100 ft/lbs. I did the same to my BeatRush differential brace.

Life is good.

 

good work--i was going to do this BUT my dual resonated midpipe will not allow me to fit this piece--so if anyone wants one cheap let me know.
olddragger

 

Thanks Juan so I guess that when all said and done the rubber after being torqued down is about a 1/4" thick maybe even 1/8" thick??? my track even is in the middle of May and trying to get everything prep'd...
Thanks ,,,,

 

Rotr8

I finally got tired of my RX8 rear dust collector (rear bumper) and found your rear bumper mod thread. I did the same but instead of using the gutter screen mesh, I used a piece of steel mesh I found while at Home Depot. The diamond pattern is almost the same and I painted it flat black just like my RB front grille. I used brush paint instead of spray cuz it is more durable and it does not chip or flakes. I also added a small wire between the center of the lower bumper (right below the center triangle) and the metal muffler heat shield to prevent the bumper from bowing out while driving at 130+ mph.

 

that doesnt look bad dude
olddragger

 

Hell yeah, looks awesome,,,, I still havent painted mine black yet, but that will be fixed in about a month,,, along with a swarray of other exterior mods...
Home Depot FTW!!! lol

 

I like it.

 

This is very nice
but I don't thinck this is very aerodynamic...'cause the air flow might have turbulence at the extraction point

Love it anyway ?!

 

I now have spark!

I recently did the Fluid Motorsports coil connectors.
Some "spare" LS2 coils from a friend.
(MSD 8247 coils are on back order)
My old Mazsport Ignition coil mount with extra washers for the LS2 coils.
MSD 90 degree boot spark plug wires.
MSD LS2 coil terminal ends for the LS2 coils.

I did not notice a difference at first, but the car seems to run better at idle and under load.

 

Good to hear!

I will ship out the MSD''s as soon as they are back in stock.
