Turbo questions?

[baderic03]

So I'm going to a 450/400 and wanna know the best single or compound turbo setup for street ability and sled pulling

Single, S475, S480. Varied exhaust housings dependig on your tuning.

Not sure how streetable but S475 & PT101-106 seem to be a good compound setup on 7.3's with big fuel.

I have a s475 on the truck. Now I just question airflow with 450/400

 

[baderic03]

I don't know how laggy a s480 wheel would be

Depends on how tight or loose you make the exhaust housing. 450/400s are rather large. lol Ide run it with the S475 you got now first. Oh and your running non intercooled still right? yeah you might want to get an air to air or a air to water...

 

[baderic03]

Yea I'm still non intercooled I was going to spray it with water meth. Or possible bite the fab hammer and put a cooler in it

If I were you ide skip the water Meth. If your gonna be daily driving it it wont be benneficial. Plus you would have to dick around with getting the spray and timing just right. Intercooler would be much more efficient.

Yea I know James there in my truck now lol they run nice down the highway w Matt's tunes

 

[7.3psd97444]

oh LOL how they run with the 475?

 

[baderic03]

Good rolling the highway at 67mph 400miles till I get home. They are deff streetable Power knocks the tires off at 50 it's vicious

Has any body on here running 400+ injectors made more power fuel only with compounds than with a single? From what I've seen it almost seems like 400cc and above is just too much fuel to burn completely with out nitrous. But that's just what I've been seeing that's why I'm asking. I would like to see a high hp fuel only 7.3

 

[baderic03]

That's what I'm going for with a single charger

 

[obspsd]

I hope it works out, now put a Intercooler on that thing lol

 

[baderic03]

I have it at the shop just like how clean it is with out it

 

[obspsd]

Yea obs can get clustered under the hood very easily

 

[baderic03]

Yes they can. So I get 16mpg with the 450/400s. Same as with my 250/200. I'm happy lol
