Tim Hogan did the intake, Island Racing opened up the stock 525 throttle body.
The set up uses all the 525 sensors.

I thought; that was a Hogan, or Wilson. I know looking at the Hogan, site their stuff has that hand fabrication appearance, which much of it is. Is there a reason you picked one over the other? What did you see in intake distribution and the limit on that intake, from your dyno, data?

Tim seemed more interested in our project.
We are still working on the intakes he is currently making the runners longer.
They make 520 ft lbs at 3000 and by 4300 are over 600.
They pull hard to 6300 where they start to fall off.

I went with a Hogan on my previous motor. Wilson would not let me come and visit the shop so I could see what they might build for me. Said there was too much top secret stuff.. He wanted to keep someone from seeing what others were running, in the racing world. So I went with Hogan and they were great!! I didn't travel to Cali to see what they would build me, but I was happy with it when I got it!!
