Im liking what you say about the backpressure.

Doesnt look like that 2400 hp target will be too hard to hit.

Lol very true.

With a 9.5:1 540 wearing brodix headhunter heads.... Im hoping it uses every ounce of air the turbos have to offer and makes closer to 2600.

How many runs did you get on the combo before you caught it? Were you at 4,400#?

The Bullseye BatMo83 is a real nice piece...with the T6 -VFL housings David has, they can make some serious steam!

Yea 4400lbs . Not sure how many passes it had , but it was around two years with the turbo and 3 years before that on the blower . The blower made about 750 to 800 hp .

The only reason I even knew the main had failed was because I broke a distributor gear , and decided to pull the motor and look things over . Also found that the Probe pistons I was using were also not up to par .

What are VFL housings ?

I wanted to go stainless , but man , it really drives the price up . Especially with the 87mm wheel .

See sig. This was at 3250lbs on ~10lbs A/A IC, 1.32 hot side shifting at 7K. It was lean too cause I ran out of injector(50lbs). I plan on trying E85 this year and see what it does on the same boost level.
