If you're saying 22 net boost, then you're saying 22+14.7= 36.7 manifold psia, which is impossible.

Thanks for the info, I just did drop ins in mine and I went .026 and .028.
Getting ready for a blower. I did a cammotion stage 2 pd blower cam . Im running it n/a for now.

it certainly is not impossible pulling tractors run over a 100 psi. O mullet put 45 in Steve Morris 35 pd engine and blew it lol.

But in my case the stats are


14.7 is seal level. Im saying that it went to 19 to 20 plus above vacuum because when the motor is running, their is vacuum right. or u could say about 230 kpa total if that helps.

The pressure was 14.36 at the dyno location.

So with out boost the engine can get to about 0 pressure wide open witch would = atmosphere or theoretical 14.7 but was 14.36 in this case. Boost is all above that.

It didn't happen with out pics right lol

It would make more tq down low but it goes rich when the meth comes on when doing lock in gear on they dyno. Never does that on the street. again in the 10 range for a bit. My meth comes on at 1 psi. and I like it. U can feel the meth hit ahhhhh!! lol

I figured you would tune the meth back with the upgrade but I see you still spraying hot and heavy. lol

LOL I love meth but only the good kind HA! Has not let me down in about 70000 miles now over 2 different cars.









Haters gonna hate lol!!!

That's lower than what I would expect, but I'm not a meth guy:

20.00
-14.36
5.64 psia boost

What do u read on your boost gauge at 1000 hp? Ur boosted correct?

[oldman]

I also have a D1X my ignition / fuel (forget on this engine LOL) cut is at 7200 RPM, I am right at your blower RPM 60K on a small pulley 3.7? I think, maybe 3.65? anyway never dynoed my car, as I ended up buying a farm in Hawaii, but I actually like the torque curve on this dyno plot, not like I'm ever going to hook it to the ground on street tires or even N555 II, LOL. My car was E85, don't know now as there is no E85 in Hawaii, probably do pulley down to 50,000 RPM 11 PSI? on 92 octane, if I knew I was going to end up in Hawaii, I would have dropped to 10.5 CR or maybe 10.0 even. Yea the D1x now is not used at all on 92 just bragging rights till an F shows up.. LOL.

I don't remember the specs on my cammotion (I custom spec it based on my TSP blower cam experience), what are the stage 1 and 2 specs if you don't mind?

I don't pay much attention to the dash boost gauge because it's just a ballpark number. I use HPT which can record 100 or more channels of data including barometric pressure, boost/vacuum, and intake manifold absolute pressure (barometric pressure + boost).

Yes, mine now has an Edelbrock 2650 s/c and it makes 19-20 lbs. (above barometric pressure) at high altitude, or 21-22# at sea level.

Kool I bet it really scoots epically with that cam

The cam I have is the stage 2, 224/240 621/612 118+4
