captain yarrr
have you tried anything lately,,,, what are you results as now

Captain YARRR 08-08-2014 03:44 PM

After more calculations and looking at the dyno sheet: my props are just fine for right now. What's holding me back from turning more RPM is my throttle bodies. I need to get some bigger ones and I can get some more RPM out of her.

have you looked at holley? Do you have some in mind that your thinking about

Captain YARRR 08-08-2014 04:41 PM

I haven't looked in to it at all. If anyone has any suggestions or experience, I'd love to hear about it. We are at least leaving 15 HP on the table with the stock one. Probably more.

I think your props really need a good lab job and you could pick up a couple of mph and some rpm with the power you have now. No doubt the throttle bodies will get more HP though. I'd send the props to BBlades this fall no matter what you do on throttle bodies.

Captain YARRR 08-08-2014 05:25 PM

BBlades told me to wait based on the dyno. Not looking at them right now but off the top of my head it makes 400 at 5200 and 400 at 5500. He says that's why it's not pushing more RPM, because it's not pushing more horsepower across the range.

We agreed: let's do throttle bodies, see how she does and probably at that point start making some changes. Maybe labbing some 25P props was his thoughts.

So Bob, what throttle bodies we putting on this winter? :)

Captain, Curious to know if you are using the stock 4 quart oil pans.

Captain YARRR 08-18-2014 05:12 PM

Yes that's all stock and my cooling seems to be working well.

Hey Yarrr, I too have a 32 Sunny MCOB with 6.2s and will be doing some builds soon. Just wondering if you found the right prop setup, did you change anything as far as shorty lowers, extension boxes, etc. and what has been your best top speed? I am itching to start these builds and going open checkbook. Any info would be greatly appreciated. Thanks

Reds9050 10-13-2014 05:44 AM

Also, why the small/stock oil pan and who programmed your ECM? Have you had any issues since the builds?
