Wow, that has to be a sandrail or drag engine with those huge snails on there.

I'd love to see a dyno run on that motor. See how much power it makes and when it spools up.

I like the idea of a cross tube to equalize pressure.

The turbos physically look huge.. but what are the wheel sizes? Lots of newer tech have massive bodies but small wheels.
That said 6psi at 360hp? Thats a MASSIVE amount of power! Is it a 3L engine or something? I would love to see a dyno here... With turbo's that big one would think you could only spool them really late. But Who knows what you spent here.... You could have some awesome antilag or variable wheel size turbos or something. |

Making big power doesn't require twin turbos. This single TIV turbo made 383 on pump gas at 20 PSI boost. Ceramic ball bearing turbo made boost from idle right on up to 6,500 RPM.

(IMG:http://www.914world.com/bbs2/uploads_offsite/www.aircooledtechnology.com-172-1379689215.1.jpg) Yes jake, but thats at 20psi... This one was made at only 6psi which is quite a feat for such large HP. Granted its a 2.8 engine so it probably made ~ 225hp naturally aspirated. What turbo did you run with on that build Jake? |
