What for rest of setup? OK guys, here is what I don't have so what do you suggest for my 750 RWHP goal from my Twin Turbo CAS t60 setup??
Fuel Injectors
Fuel Rails
Intake Manifold
Suspension Musts
Also just a couple of Q's. Will 3.73 gears be a good gear from my 4L60 E and 12 bolt Moser? I have the LS6 manifold, but was wondering how much of a power increase I would get with the FAST 90?? Than

3.73's in a 4L60E with 750rwhp?
factor in a tranny while your at it...
You can probably push Mot 60's to that, but the duty cycle wouldn't be all that great. You might want to look into 75's not running standalone
Speed Inc sells rails, so does Nasty Performance.
LS6 or LSX, the polymer does fine under boost...
torque arm, antiroll bar, LCA's, panhard, Hal's... get ready to spend a little bit getting that tub to hook.

Built tranny My tranny is built from RED Alto. It has upgraded 9 clutches, kevlar bands, hardened shafts, it can handle it. So what about the 3.73 gears though? And what about the injectors, this will be by daily driver
Toss a methanol kit in there, that will make the 60s fine as well as give you some add'l safety on the street when not running race gas.
I wouldn't waste the $$$ on an LSx intake, you will be fine with the LS6...the Ohio Boys went 8.3x on an LS6.
For a 750rwhp car I would not just do rails, I would do the whole fuel system -8 feed, -6 return with either a Racetronix intank setup or two external pumps and a 1:1 regulator.

ttt I am getting the upgraded fuel system as well, but I was told that twin Walbro intanks, or externals would be good, which one, and where do I get a meth kit? Are ya sure 60# injectors are going to be sufficient??

I think 60's or 75's might be cutting it a little close

For added safety you could always go to the 75lb/hr. injector and the meth kit. If you want the 750hp to be available on the street without race gas then the meth kit is the way to go. I believe MM is running the Snow Performance meth kit, one that always looked pretty neat to me (and the turbo buick guys seem to love it) is www.alkycontrol.com.

fuel system OK guys here is the fuel system I just bought, does all this sound about right minus the fuel rails and fuel pumps?
- tank with welded-in fittings for the feed line on the bottom, and the return line in the top (through the stock sending unit area).
- 90 degree fitting to get from the tank to AN line
- AN-10 line and hoses from tank to filter inlet
- AN-10 inlet/outlet filter
- AN-10 line and hose ends from filter to pump inlet (your pump should have come with an adapter fitting to make an AN-10 inlet and AN-8 outlet)
- AN-8 lines and hose ends from the pump outlet to the front of the car (you will need the fuel rail fittings that accept -8 line, along with the fuel rails of course)
- AN-8 line and hose ends for the crossover between the fuel rails
- AN-8 line and hose ends from back of rail to the regulator
- boost reference capable regulator with fittings to accept AN-8 line inlcuding blockoff for unused port
- line and hose ends from regulator back to the tank
Now I just need injectors, Meth kit, and fuel rails, I think I will be getting the one suggested from alkycontrol.com for $425, I thought it would be way more than that, anything else I need as far as the turbo, of yeah which guages do I need? Thanks.

already bought I am buying it now, I sent the first payment, the in about 2 weeks I will have the rest for it. I bought Moser 12 bolt with 3.73 gears and I am having J Fuddle custom build me a stall for my application.
Some thoughts on the fuel system...if you are going to run -10 from the tank to the pump then you might as well run -10 to the front of the car and Y it into -8 as the rail feeds. I would have two -6 outs going to the regulator and then a -8 return line.
I always like the equalization better in systems that feed both rails...just my preference. Also, I assume that you are going with a large external pump...I have heard that this is not the greatest setup for a daily driven setup unless you are using a step-down box. If you do decide to go with 2 pumps I would have individual feeds from the tank for each one and a pre-filter for each pump...then another -10 filter post pump on the way to the rails. In my opinion the fuel can never be too clean!

I'm not really sure how the dual intanks feed...I'll let someone else respond. What I posted above is the fuel system that I am running...except with external pumps.
The internal guys will know what you need.

You could probably go with AN-8 feed and AN-6 return. AN-10 may be a little overkill. Also that is asking a lot of the 4L60E no matter who builds it. I guess if it doesn't hold you could then do a switch.

ttt yea, the CAS kit doesn't fit with a TH400 though, the shell is too big I believe, but if this tranny doesn't hold, i will probably do this and maybe notch the sheel for clearence, could that be done? AlsoI want to run 60# injectors so would a 10 be overkill? Wouldn't it just be safer? Thanks.

From what I've read I think that #8 would more than do the job. I think I read that INTIMID8 still has parts of the stock lines (800 + rwhp) and so did TwinturboCE (9 sec 1/4). I think the stock feed is comparable to #6 line. If you go braided I would use the teflon line to avoid the gas smell that seeps through standard line. I had to redo my setup with teflon because I hated the smell that you got when it was closed in the garage.
60# injectors will be fine. People have made 850rwhp with 60# injectors. Make sure you have a good pump such as either dual 255's or a big external (big external would be best). Make sure you run your fuel presure at 60PSI with a boost reference regulator. Which also means you will need to do lines and fuel rails to convert to a fuel setup w/ a return to the tank.
For the converter you should go with a 3600-3800. I tried to use my PT4400 when I went with the Vortech and it was way too loose( it worked great NA). Also I was hitting the rev limiter with 3.73s and a Century built 4L60 at about 1100' so I went back to 3.42s, that will probably be good at your power level also.

tc yea John fuddle is custom building me one that stals somehwere between 3800 and 4200 stall. The 3.73's are going to be ok for me, and the tranny wil hold up a well. Thanks does anyone think I ought to just install the -10 because I plan to turn it up even more in about 6 months when I pay the car off So I don't want to have to redo anything, thanks.
