i think i have seen his website BULLCHIT STROKIN PISTONS,WITH OUR PISTONS YOU DONT NEED NO STINKIN BOOST!

I am highly intoxicated at the moment, and this still smells like ****t.

Dan , lets shoot for 12.5 at wot. Mike and I need a winter project. Make sure you hold it pegged good, we need to upgrade heads while we're changing pistons out

I always wanted a 150mph skater that gets 25 mpg and passes the smog test

150 mph with less than 6 lbs boost,his engine must have been built in THE MAGIC ROOM.

We all seen the movie but Please don't tell me he wrote the book to.

SKATERMAC,im always trying to learn,what engines do you have in your skater,and can you give some info,like what type of power adder and what your total timing is set at?

They where 1350 Sterling to start with. I use most of Mike's recipe. I run cams from Hollman Moddy custom ground. They are very small but will run to 7500 and idle at 700 rpm. My ignition system is fully programable it has boost retard, retard for curb idle (neutral) and i run a timing curve; 36 degree total. I run race stripped 10.71:1 Mooneyham blower at 1.1 over drive. Special surface gap sparkplugs. I tune with Innovative O2 AFR meters in the collectors. I run blower shop intercooler forward motion feed only. I have single stage waterpumps raw-water only at 150 degree water temps. Twin in line modified 1150 Holley 3 circuit carbs(power-valves front and rear) 80 Mains Squared .080 PVRC 4.5 and 5.0 above the blower with the intermediate and idle circuits this equates to a 112 main jets at full throttle acceleration 12.9:1 AFR

I`m sorry man but the idle air circuit has nothing to do with primary or secondary jetting or any AFR numbers above idle. Ive got it as lean as it will go without dying when shifted and its at low 12`s at idle.. 14.7 aint happening.

Was hoping someone with some actual carb tuning experience would have chimed in (not counting Mild or Tkat of course) no biggie, we`ll get this figured out. I`m going to restrict the fuel dump thru the power valve at 4K and see what happens.

The advice I got from Nickerson today was to add a secondary power valve.. umm ok cause the primary valve fuel dump just wasn`t enough?? :picard1:

What in the world????

Well if i knew what i was doing maybe i could get big trouble into a lower et bracket,,it has 2 dominator carbe 4 stages od nos and more jets then yours , mike's and joes all put together and we manage to get it down the 1/4 mile race track in 6.87 seconds @ 210 mph..
