1. Pricing? How much are these going to cost?
Answer:
They should run in the ballpark of $650 for the ceramics.
2. What is the projected benefit of the headers?
Answer:
On the 4.7 Tundra we gained 28 hp and 39 torque at 3800 rpm. That is a huge power gain. Also anytime you increase efficiency your mileage will significantly improve as long as you keep your foot out of it.
3. What installation issues will there be for the do it your selfers?
Answer:
These will be a direct smog legal bolt on application.
4. The projected timing from when the 20-25 limit is met until we get them?
Answer:
4-5 weeks from time development is wrapped up.
5. Spreadsheet is the dyno spreadsheet for the Tundra.
If you're interested in these headers for the Toyota 4.7 V8, please leave a note attached to this post so I can get a count. I will also be posting this message over at Yota Tech and Toyota120.com, so please only post one time so I can get an accurate count.
REMEMBER, if you are interested in these headers, Doug Thorley will require you to contact them and leave a credit card number. The total BUYING customers needs to be 20-25 before they will start.
Thanks,
Brad
