S475 single turbo ?
- Thread starter DuramaxPowered
- Start date
Made this little plate to slip in front of the turbine inlet on my S475 when I got home from work........I loaded a tune with 0% vane position across the board too:roflmao::rofl: .............Results were interesting
Well? What you think?
Oh but it is the shit by itself! I ran 115.9mph with it last night as a single turbo fuel only single pump on my truck. That is 1mph less than my best ever time with the twins! I am personally beyond impressed with it!
The lag wasn't as bad as I thought it would be........let me figure out how to post a video of a 35PSI boost gauge bouncing off the stop, rolling into the throttle (from about 20-50%) :happy2:
no, and don't wanna:roflmao:.........I was testing this purely to see spoolup/response. my plan, if I do this as a single, is to open the 2nd exhaust port at certain boost so spoolup lag is minimal. Turbo gasser guys are doing this with great results. I think we can too. This will actually be pretty easy to do/test, and I'm just looking to do something a little different even if it's wrong.
http://www.youtube.com/watch?v=3vApQPiyhoM&feature=channel&list=UL top boost gauge is 0-35, 2nd gauge is total boost 0-60, other gauges not hooked up. the small turbo is still compounding boost, so this turbo by itself will spool slower I'm sure. like I said before, I was kinda surprised at how it spooled. I have a tight ass converter, and stock cp3/injectors
Trent what do you think a setup like that would be capable of with 100 overs and dual fuelers?
Keep in mind I was NOT going wide open, but boost was 45-50 total. Like I said earlier, the stock turbo is having an effect on how fast the spoolup is. To what extent I won't know until I get it removed and test more. I am also going to get my back pressure gauge hooked back up, and fix broken pyro gauge. If I don't like the end results, I'll put a different turbo back in the valley.
What boost and back pressure #'s are you guys with an S475/83mm/.9AR seeing? What do you have for fueling (injectors,dual CP3's)?
48 psi boost, I dont have a drive preasure guage. My charger does have a billet wheel, I dont know if that raises boost or not?
I have the 87 turbine and it makes 55psi. 40% nozzles, big Hamilton cam and a stock pump.
