1. What exhaust a/r do you plan to use on you 60 trim T04E?
O-trim .69
2. Do you plan on intercooling? if so what method, and size of IC are you planning on?
Front mount, I'll have to measure it and get back. FWIW is a custom Starion IC
3. How does an engine increase rpm on the dyno with no throttle application?
No resistance being put upon power output from an inertia measured dyno when throttle is held constantly
Trying sticking your car in 5th, apply a constant amount of throttle (not WOT) the car will slow reach its terminal speed when wind resistance overcomes power output
4. Why would anyone not want a complete dyno pull? (ie why not get the complete pull when you have to accelerate through the lower rpm anyway)
Like I stated before, cars with little torque in the low revs will take alot of time on the dyno. Starting at a higher rpm will put the engine in the power band thus taking less time. Its also a possibility he was having tuning issues. But I spoke with them on the phone and he said its running fine. I didn't bother to ask him about the dyno.
5. If peak power isn't your main concern (otherwise you would be beefing things up, etc.) why wouldn't you consider a turbo that would be better compromise of efficiency between the 2 levels you plan on running?
A T4e can run 400-450hp effectively
A T3 60-1 can run 300-350hp effectively
A T28...
I really want a HKS 3037 but its $2640 
So I have to settle with a T4e thats going to cost about $1500. A T3/T4 would probably run me $1100
Its possible a T3/T4 hybrid would be the best for my setup and even a little cheaper. But the Duratec likes to breathe, should I go with a smaller turbine it would generate more unwanted heat from an elevated backpressure ratio and less power.
Plus I've worked T4s in the past on smaller 2.0L 4cyl (SR20DETs if there are any Nissan owners out there) engines with no spooling problems. And now with ball-bearings center sections they look even more promsing.
Are we still on for the bet?
