Jtran Studios low mount single turbo setup completed!

O&G · 10-25-2011, 11:18 AM

more pics later, all I have rite now are shitty cell phone pics, I added a few more to my album of the car, I'll post more later, with Dynojet numbers as well. The collector has a baffle in it to prevent the exhaust gas from having a tumbling effect.

Highest cooling temps I've seen are around 210! OK, I'm out talk to yall later, time to DRIVE!

two inch schedule 10 pipe to a two into one collector with a divider plate between the collector to keep the exhaust from tumbling before merging all the way to a 2.5 to 3 inch concentric reducer on a t4 flange. schedule 10 pipe is used due to the strength of the material compared to traditional gauged stainless. both feed pipes are asymmetrical so by therory it should scavenge the same between the two banks. that should answer the questioning on the hot side piping.

I'm confused, is the pipe headed to the T4 flange 3" going to 2.5" or the opposite? I would think you would not want to increase ID right before the turbine since you would get a pressure drop and loss of velocity.

car8oy281 · 10-26-2011, 11:00 AM

opposite. 2.5 inch to 3 inch. pressure drop and loss of velocity is minimal. might make a difference in spool by 100 to 150 rpm but nothing crazy. car makes full boost right around 4200 to 4300. gate is being pushed open prematurely due to wastegate location. i would rather it hold boost solid then spike then come back down.

What's the rough area of the opening of a T4 flange? Assuming a 3" ID pipe has 7.06 square inches of opening.

In for updates.

O&G · 10-26-2011, 01:55 PM

Dynojet numbers tomorrow, with exact boost reading, compared to the Mustang dyno we used to tune the car. We just completed our second oil/gas well in east Texas so between work and this turbo project time is very tight. I'll get back to you with exact pipe dimensions, flanges, collectors, etc.. as soon as I can.

O&G · 10-26-2011, 03:25 PM

2.5 inch to 3 inch reducer into T4 flange

9500 for a single turbo that we dont really know much about seems a little high? Or is it 9500 installed and tuned?

Thats droped off and picked up under 10k. Pretty good deal imo.

Boost isnt cheep. Single turbo kits can make as much as twins. Its just a matter of what you want. If your really interested just call the shop. Pretty sure johnny will answer any questions you have. Its just another alternative for our platform. I know hes doing one on a G37 next but these are all local customers who know johnnys work and history with the VQ. Dyno graphs will be posted tomorrow.
