I know of one builder who just made 1360hp @ 12.5psi of boost, 93 octane, pump gas, 604ci, no methanol, expecting 1450 with methanol injection. Whipples made 200+ hp more than 1471 with 2.5 less psi. Thats by far the most I've seen for a performance engine. Requires big chief style heads.
Just curious.
I know Mark did back to back on a roots vs. a 5 liter. Was that your engines AJ?

Gunna dyno a set of 600s with 1471s ,BIG chiefs, 7500 rpm bring some 5.0s down and we can run then same dyno ,same motor,same day and post the dyno sheets on OSO & Serious offshore.com![Ernaehrung004](/forums/images/smilies/ernaehrung004.gif)

260 :
Jim Lee slowed down after installing 5.0s and is now running PSIs. Like I stated 20gs give me something in writing that with 400hp gain I will see at least 15+ mph or take them back.
Skater has been around long enough and HP = speed = Skater dyno
Hope you all are having a great time a be safe I sure wish I could have made the trip.Maybe nextyear.

Just to keep this on track, Jim did not slow down. I am pretty sure he picked up a little and has better acceleration. He also still running 5.0's and is very happy,never switched to PSI's.

He had 10s and after the dyno it has run all year with no trouble better idle much more acceleration and more top end. We made 100 more hp over the 10 @ the same boost. we made the same hp as the 10 with 3 less # boost. It made 1250 hp with 12.5 psi on a 565 inch engine 6400 rpm. Joey Griffen did back to back on frank L eng and gained 85 hp same boost over blower shop 14/71.
Dustin was at sema not pri now he is with us in Key West I think he will chime in when he gets home. I am on my pain pills and too much alcohol to type any more
