delete intercooler; add nitrous
The PTE 88 is a good unit and he would make more power with a sx88 yes. Although it wouldn't be much as he is more limited by the turbine housing. The n20 is a valid idea to make more power, e85 and such will not make more power especially with a already chocked up turbine housing. I think you would be looking to lift the heads more then any thing. Best route would be to upgrade the turbo drop weight and then maybe think about alcohol/e85 and base your turbo selection around that.
For one you will need to switch the car over to Alcohol. This will require a complete fuel system change.. Then during tunning this system you will have to lower the boost and work up the tune with adding boost and nitrous while watching the airtemp.
At some point you may find your self spraying more nitrous and lower boost in order to keep it cool.

you cant simply change for gas to alky and think everything will be the same,with alky you double the volume of fuel going into the engine-so you lose runner volume in the intake ports due to the extra fuel,also cam selection is totally different-comp ratio,the other problem is that with alky your exhaust volume increases-Mightymouse is allready restricted with his little *** pt88-adding alky will just increase backpressure,reducing power
David,i had a customer put n2o on his s/c car to do the same thing,it was a 350cid sbc with a smaller vortech-pushing like 8-9psi,he added a 125 shot,the iat's dropped 2 deg

So, would you drive on the street with a really low boost setting and rely on only the meth to not get the IATs too high, and then only use the N2O at the track when you want to cool the bigger boost? I just don't think that is a very good idea. It will make for a more boring street car with the potential for non cooled damage, and it appears it would take a 500hp N2O shot on top of the boost to cool the IATs even a little. You will probably choke the intake ports with all of that fuel and N2O and choke up the exhaust before the turbo.
Why don't you switch to a decent size A2A front mount and continue to use the Meth as needed?? Then if you still want more power and a little more cooling use a smaller N2O kit at the track.
Maybe you should just leave the A2W in there

. I guess you dont know how far Arligton and Richmond are from each other and how bad driving to and from DC is (arligton is right there by DC)

Something tells me E85 will be selling good at performance shops in your area 
IMO nitrous is a good way to go, I'm putting a dry shot on mine with an FJO progressive controller but will keep the A2A. Figure I can give the true street boys at Memphis a run for their money if I can get consistent mid 8s. I have everything for a real nice A2W but with water is going to weigh near 100lbs and I cant afford another 100lbs right now.
When I ran my old P1SC and a 50 dry shot the IATs dropped 50+ degrees and the sensor was nowhere near the nozzles. That was one of the best street setups I had. I figure a 100 - 150 shot should net me at least 1/2 a second in the 1/4.
Downfall (for me) of course is its not legal in a lot of classes but a few of the classes I run in are simple tire limited and who cares whats under the hood so I figured I'd give it a 'shot'

Hey get a 55gal drum.. lol. Sucks yall only have 1 station there. We have 3-4 in Houston and one 3 miles from my House. However where my car is getting tuned there is none (Fort Worth) so I have to bring a 55Gal drum with me Something tells me E85 will be selling good at performance shops in your area
Something tells me E85 will be selling good at performance shops in your area NOT true!!! There is 1 in Irving/Dallas/Sachse/Plano/Carrolton/Crowley/Mansfield/etc.

I believe that Cablebandit tried this on his old incon setup, and ended up putting the intercoolers back on the car, even though they were horrible to begin with. It's just too hard to cool all that hot charge air down with meth/nitrous when you're running a gasoline motor.
Also, DrTurbo on another thread was talking about a new compact high hp turbo (1,400-1,500 hp) they are coming out with next week.
"If you want a small and high flowing turbo around 91mm power, but 88mm spool. We are working with Garrett on a compact GT47/GT55 hybrid. Will be the size of a GT42. The CHRA is already done, we are just working on the housings now. Good choice for about 1400-1500hp."

a/a is not going to scratch the iat's i can get with my a/w
my intercooler is aluminum so please hold the salt
yes it might take a larger amount of nitrous than i anticipate.. how can i figure out how much.
again i do not have acess to e85 nor run the car on straight alcohol.
my tubo is a pte-88, i have space limitations

What are the air temp now pre intercooler. Whats the pressure pre intercooler and after intercooler. What rpm. etc etc.
Nitrous is not just cooling you will be adding more oxygen. just adding nitrous only will make your car much more violent. I think the amount of nitrous needed to offest the hot air temps would be pretty hi.
Lets say you are making 800hp but air temps are 200. You add 100 HP worth of nitrous at -127. The huge diffence between the two would not allow the nitrous to do much cooling over all but you did add a more oxygen. There is just too much hot air. Now if you where making 500 hp and dump 100 worth of nitrous you would see a very nice drop in air temps. These are just examples and thoughts.
I think you might get some data from the truck deisel guys. They see stupid hi temps, and use alot of nitrous to get more power. Someone might be looking at air temps while watching egts.
