Ok, work delayed me a bit but I finally got more data. I took the turbo to Turbo Auto Diesel here in Phoenix and had them look it over. They say there is nothing wrong with it and the wastegate is working properly (WG valve seat is good to). So I put it back on. I built a plate to block the hole left after I removed the BOV valve. I disconnected the intercooler due to the amount of leaks I found in it and the charge air tubing I made so my #'s are a bit different than before but still not right.
Here is before...
In third gear cruise
2500 rpm, 40mph, 700 degrees, maybe 1lb boost
3000 rpm, 48mph, 800 degrees, 3 lbs boost
3500 rpm, 56mph, 1050 degrees, 6 lbs boost
Here is now...
In third gear cruise
2500 rpm, 40mph, 1000 degrees, 2lbs boost
3000 rpm, 48mph, 1150 degrees, 5 lbs boost
3500 rpm, no friggin way.
In 2nd gear when I floor it I don't see 10lbs boost until 3500 rpm and then it ramps up quickly seeing a max of 24lbs boost at 4500rpm.
In 3rd gear when I floor it I donlt see 10 lbs boost until 3000 rpm and then it ramps up to a max of 20 lbs at 4000 rpm.
The lack of an intercooler, even a leaky one is noticable. My tire size and diff gearing are an issue also. 34x10.50 swampers are a true 34 inch tire, match that with 4.10 gears and 1st gear is a little boggy to start. I'll probably change to 4.88's when I put in lockers. So here are a few questions.
1. Is 24lbs max boost reasonable from a Giles pump setup for 120hp and a stock T3?
2. Floored, when should I see max boost with this setup? And when should boost start to ramp up.
3. What is the resonable sustained use upper end for boost with this T3?
I have access to a buddy that can make a custom intake and exhaust manifold for a twin setup.
Is this the route to go? As fun as that might be I would like to avoid the down time and cost associated with it for now.
All I am looking for is the ability to cruise the freeway at 70 mph. The rest is gravy.
