Hello!
I recently picked up a 2.4 Turbo for my 1984 Dodge Rampage and now I'm going to size the turbo I need
Background:
1. The Dodge Rampage is about 2,200 lbs. I plan to drive the cruck mostly for picking up Craigslist antiques and other furniture for restoring and selling, with part time duty for picking up other engines for 5.0/misc engine swaps. This will be mostly a work truck with a part-time track slut duty.
2. The engine will be backed by a 3 speed auto with fairly tall gearing.
3. I'm going to aim for good gas mileage and green-rod it.
Questions:
1. I want to aim for a safe level of power on the stock block. This should be around 400 whp from what I've read. Is it generally safer to run higher RPM, more peaky power from a big turbo, or a fatter torque curve at lower RPM?
2. On your last turbocharged vehicle, did you prefer a laggy-but-powerful turbo or a quick-spooling less powerful turbo?
3. Do you get better mileage on a laggier turbo that you tend to shift before it enters boost, or can you get better mileage on a quick-spooling turbo by utilizing the lower RPM power available?
TL : DR
I'm trying to pick a turbo for my 1984 2,200 lbs Doge Rampage that will be able to put out big horsepower at the track while getting the best possible gas mileage and drivability around town, looking for suggestions. I don't want to hit boost and catapult a desk I'm hauling into the windshield of the car behind me!
(p.s. a member of RS offered to sell me this turbo:
Garrett part #466159-5003
COMPRESSOR SPECS:
Flowrate: 50 lbs/min
.60 A/R housing
60 Trim whell
T04E housing 2-3/4" inlet 2" outlet
TURBINE SPECS:
.63 A/R housing
Stage 3 Wheel
- Supports up to 450hp
Looks like a good deal but I believe I may want a turbo that is capable of 500-600 so I don't have to upgrade for serious track duty.)
