Quick run on 10lbs boost, 10* timing. Dip is due to spinning out.

That a lot of engine for that turbo. Check your back pressure before cranking the boost up. Just to be sure it's not crazy high.

sierra416

For sure. That turbo was spec'd by Precision for my 6.2l 800hp goal. The turbo flows really good and the boost hits quick for street. Btw it's a Trick Performance Stage 2 kit with some upgrades.

George C....

give you example.....i have two of those turbos for a 427

Rick turbo kits are great and if your power goal are met your good. I was thinking Ricks upgrade kit was a S480 with a 83tubine.

sierra416

I bet that thing is nasty.

Byrdman- the stage 2 biggest option is 7675.

No doubt a bigger turbo would probably be a better match but this is strictly street truck and works perfect for what I'm looking for.

Sorry Sierra. I did know that info. 700hp is badass. ��
