How big of a difference would it be from 9.5 to 10.5psi? Is the installation on the RippMods Water/Meth Injection difficult?

Hp should be 8whp-15whp all depending ....I dont know anybody running a 10.5 pulley so i cant even ask. But the range should be 8-15whp. The install was done by RIPP. Took them about 2hours with 2guys working on it. They had to jack the car up, take the tire off, mount the pump under the wheel cover, tap into the windshield washer tank, run the tube for the methanol, run the power line for the methanol, and then put everything back together.

Its not a hard install ...but just a bunch of small things that built up time. It made it easier for them to pick the car up on the lift .....that way they were looking directly at where they were mounting the pump ...etc etc.

Why not go straight to a 12lb pulley like Karl did? Or did Perry say not to?

I dont think its a smart move for long term engine performance. I am getting my car back from the dealer on monday/tuesday w/ my lsd/clutch/flywheel

My s/c warranty is now void after this visit since aftermarket parts and TRD dont mix. Its honestly bull because everybody and their brother knows what I have is not going to be the "cause" of any s/c problems. BUT - TRD said that they will pay for the new shaft and I will pick up the few hours labor it took to put the charger back in. For now I am happy but who knows for how long. If anything big goes wrong w/ my charger is comming off and im throwing a turbo on, fixing the charger, and selling it for a good price. Simple as that.

Yes, I believe that is also a way to achieve higher than 14psi, but likely only a 1-2psi increase over 14psi.

I gotta question about the tune? Are you actually planning on getting it dyno tuned?or just getting the TRD reflash? Im curious because Im thinking about the supercharger and if I get it i want to run the 9.5 pulley.

thats what Im going to be doing, im going to get the 9.5 and have it tuned with my emanage ultimate. My only fear is when going to 9.5 causing the seals to leak. As far as I know, there isnt a rebuild kit for the S/C but garage1217 did take it apart. Is there anyone running the 9.5 for quite a while and not experienced oil leaking from the S/C?

I just bought a 10.5 pulley and should get it in another 3weeks or so. People are running 12lbs and have been free of problems. 9.5 is safe and NST did a test with a 10lb setup and it was "iffy" ...meaning that you can use the TRD tune with the 10lb but you shouldn't. My 10.5 with the eman ult is gonna give some sweet numbers. I know a guy that is getting his 9.5lb tuned w/ the eman. He will have methanol and a header back setup. I cant wait till I see the results. I should know by wednesday night if anybody is interested.

I bet the leak issue was with TRD themself because that was only happening to a certain amount of people ....and u really dont ever hear of that issue ever anymore. There is always a % of people that will have issues with any part for their car. I have solid proof that TRD changes parts and part numbers on their parts w/o telling anybody. This is because they make small changes in parts where they know they have problems. A good example of this is that the TRD s/c mounts ...they were 100% designed wrong and TRD knows that ....they didnt do jack about it. But with the 07 s/c they have better mounts. If you get a s/c installed on your 05/06 I believe they use the 07 mounts and have totally stopped making the older mounts. I have pictures of my old mount that broke. Its clear as day that it was a stress crack.

and get whatever belt NST says to get w/ their 9.5pulley and you are 100% correct - no issues. Its a proven fact from a year ago. NST actually sells the belt you need on their webpage. When I got mine I would have prob bought it from them since your saving the trip to the store and tax.

I have the methanol kit with my 9.5pulley because I was preparing to get tuned. If you are going to stay w/ the 9.5 pulley dont bother with methanol ....you will only get a few hp off it. When you get tuned you can gain like 20hp from the methanol and also keep the car safer
