Finally making some progress on my twin turbo project. I ended up with twin 78mm Precision turbos that will be run on a 512 IA2 run on methonal. Hope to have the engine on the dyno by the end of June if I get all the parts bought and the shortbolck built before then. At least thats what I shooting for, doubt I'll have it ready to run in a points class but at least I'll have time this year to test it out.
I still need to cut my old cage out and install a 25.3 cage, new rearend and re-do the tin work. Its going to be a tough few months trying to get it finished. I almost got the "easy" header done, except for one tube I need to re-route. I'm sure the driver side wont be finished as fast. But luckliy I have to re-route my steering for the rack anyway so it wont go in the stock location. I had 2" tube bought for this but it didnt take very long to figure out I couldnt get the radius I needed to clear the A-Arms so I went with 1 3/4" tubing the entire way. I was also looking for a 4-1 transition to the turbo. Everything I found was over a $100. I couldnt see paying that for 4 tubes and piece of 3/8" flat so I built my own. Did some research and figured out the correct angles need to make it work. Built it from .095 ERW tubing and 3/8" flat. I tried using the 16ga tubing but it was tough trying to mill out the miter cuts on thin tubing. The .095 allowed me to make bigger cuts and the tube still keep its shape. I bought all the materials to build a set out of stainless but decided I wanted to use mild steel first in case I made a lot of mistakes. My plan is to run low 5's in a drag radial class at Eddyville or KCIR. I would like to hope I can push the car to 4.90's but 5.20-5.30's will be a handfull to start out with. I still have to get the second set of injectors installed and the entire fuel system bought and plumbed. March is going to be a expensive month....... New JW trans should be here by April havent picked a converter yet. |
