Jim, are you still running the stock intake manifold... if so, wouldnt a higher flowing one help drastically with the new head?

Well done Jim!

How do you like it on the road? It must be insane.

Mike, that is an excellent point given the increases TonyG found in his mods to the intake manifold. Hmmm, 500whp on a mustang dyno???

It is still stock intake manifold and stock intercooler. The intake has been port-matched to the sledgehammer - that is all.

The ignition is actually stock, at this point - NGKR 7's @25 thou.

I am sure the spark will smoothe out up top with the wasted spark.

Here is another tidbit for anyone who cares - all runs today were on 50 % xylene and 50% 93 pump. I have never experimented with this high a content of xylene because I was worried about possible ignition difficulties. However, I would say that the gamble paid off. The 951 wedge likes straight aromatics - it is as simple as that.
By the way, 50/50 xylene/93 yields an octane of about 105 - and a voracious flame front speed.

Hey 2005 is not over yet! Give me a chance!

Lets see........475rwhp + 71hp (15% driveline loss) = 546 crank hp!

I feel sorry for your rear tires.

Bill - don't sell me short brother. This is a load dyno, not a dynojet. Little more than 15% loss to crank HP.

I'll take 10.
