370ci, rear mount - suggestions?
E85 is like 105 octane or so. You can run a bunch of boost before you need methanol. You need 30% more fuel volume though(and 20%-30% worse on miles per gallon). So if you had a fuel pump that was good to 1000hp on gas it's now only good to 700hp. Same for injectors.
haha - yea no problem. we don't have e85 here.. i would have been all over that if that was the case
Another typical noob question I am not seeing when running a search lol
2-Step!
What needs to be done to make it happen?! Anyone experience any issues with rear mounted turbos?
ALSO!
Will a Tubular K-Member help with clearance so I can bring the charge pipe up higher away from the ground?

The downfall of the rearmount with the power goals is the serious lag it will have and the backpressure on the exhaust valves. We ran a T70 on a 346 which made 700rwhp at 16lbs of boost.It would full spool at 4-4.5k rpm compared to a front mount turbo we did after that would full spool at 3k rpm.
Another note,with the 16lbs the car would lift the head gaskets during WOT 4th gear pulls down the highway.

if that is all just get the block or heads oringed and you shouldn't have to worry about pushing water. I am not sure if lifting the heads and pushing water is the same thing here but there have been guys with more psi doing fine with the rear mount. I am currently going to invest in a 2-step but I have books to buy for school so it will have to wait a month. I am probably going to get the MSD one from summit.

What numbers are you making?? Sounds solid

Would the ST80 1.0 a/r work well on this as well? i saw something on zombie's - seems to be making power and using that quick spool
is the TC78's exhaust divided/TS for a quick spool?

housing a/r and rear end gears make all the difference in setting up a high horsepower rear mount seems to be much more important than a front mount.
ST80 or SX80 will indeed flow more and have less backpressure issues. I would go bigger than 1.0 on the AR. If you are going to use a quick spool, go like 1.2-1.3 on the AR. The TC78 can be bought with a 1.15 divided housing that you could use a quick spool valve on. You need to figure out what HP you want to be at the crank and size your turbo from there. Up to 1000 the TC78 would be great. You want 1200-1400, then you should get the ST or SX80.
Yea for simplicity sake I think I may do the TC78.. Still thinking about it. (I thought I saw something about a GTS version - could you elaborate on that DrTurbo?)
Also, I dont know if this was covered - but is a Turbo Tubular K Member useful with a rear mounted system? Or just grab a plain old Tubular K Member? Figured while I am there, save some weight..

okay so for a rear mount which of these turbos would out perform and out spool (can you put them in order by best to worst in each category) GTMT78 TC78, GTK1000, and T78?
