My Week with a new "Attitude"

[BMDMAX]

I received my new Hot Attitude from Kennedy last week. Excellent service, I got it right away even with the short notice.

Driving Observations:
I have been running the Quad 215 stacked with a Hot Juice 125 for quite some time. The Attitude 145 stacked with the Quad 215 is sweet. No more lazy shifts and the power is fantastic. It is very drivable around town but be prepared for some stout EGT's. I can peg 1700 plus on the 1/4 mile passes with ease.

Attitude Gauges:
Very nice display. I like the ability to have four separate pieces of info displayed at one time, I have EGT, Boost, Engine Temp, and Engine Load displayed at the moment. The EGT probe is very reactive and gives a good indication of what is going on. It reads much faster and higher temps than my SPA DG211. I have one probe on each bank.

I have been running 13.1 second passes in the 1/4, I think that this stack will yield high 12's. I will find out at the track this weekend for sure.

Here is a pic of my controversial 515.6 HP dyno run. :cool:

I like the stack too.........135 quad and 145 attitude seems to be a good one also...........have noticed some pilot injection noise just barely on power around 2000 rpm but its there without the stack and I think its more inherent to the quad. Great power

I agree, the Quad tunes all have a bit more "rattle" at that rpm range. Tow Haul makes it really loud! :cool:

Have you noticed the slight surge with the 215 tune?

I am running the truck at SDR this Saturday if you want to get some 1/4 mile passes in.

yes I have the surge too......wish I could, got lots of ongoing projects

BMDMAX, How much boost are you running and what is your best 1/4 mile mph, if you don't mind? I have gone 99mph with the Predator 65HP stacked with the Hot Juice 120HP. That is the kind of power I want but don't think I will get there stacking an Attitude 145HP with the Predator. Guess I am going to have to step up and buy another power module.

JR,

Best ET to date is 13.14 @ 103MPH. That was with the Quad 215 stacked with non-Attitude Hot Juice 125. The Attitude 145 stacked with the Attitude Hot Juice 145 feels even stronger and there are no lazy shifts like the 125.

I think it will drop into the 12's but I will find out this Saturday at the track for sure.

The boost measured at the wastegate line with my SPA DG211 yields 33 pounds of boost. The attitude is measuring 25 pounds but I don't know where or how it gets that value. Anybody know?

I ran the HJ 125 with all of the Predator 1.04 tunes (40 to 100) and while I shaved some time off the ET's the speed never got above 100MPH. Plus it shifted poorly with that stack and the EGT's were not really worth the minimal power gains.

I don't know what your plans are for a tranny but you will need an upgrade. smile.gif

The Juice cannot measure above 25 psi...

I forgot to mention I have the Suncoast Stage IV tranny. I went 14.0 @ 99mph the first time to the track with the new tranny. That was with the Predator 65HP stacked with the Hot Juice 125HP. It should have ET'ed better but I think I had a bad ProLoc converter. The 1-2 shift just hung at 3000 rpms until the converter locked up. Joe sent me out a new one and I installed last weekend. Haven't run the truck yet. Wautung for my Attitude update to come back should have received it Tuesday but the mistakely shipped it ground instead of next day air. I have seen 34 psi of boost post intercooler with the wastegate hose disconnected. My egt's on my best run barely go over 1300.
