Dyno numbers for ATI

This is on my SCREW 01 with an out of the box tune. Again this is no trix just the blower (stock 6-9 psi) and the superchip (custom burn).

Average run was 350hp with 408 ft lbs of torque. I will have my site back up in about a week and I will have pics of the truck on the dyno as well as scans of the dyno sheets.

I also have the stock sheets and a kenne bell comparo. Stock with the 95 mph cut off it shows 202 hp at 4500 rpm. This will translate into approx 220 at WOT.

We ran a 99 4.6 with a kenne bell and it was 250hp and 317 ft lbs of torque.

All ATI guys: We need bigger injectors. My injectors crapped the bed at 4800 rpm. On the sheet you will see the fuel air go lean at that point. We can easily see another 5 -10 hp with proper fuel in the upper RPM range.

I am working on a program for 42 lbs injectors so we can take the FMU out of the system. This way we can use the chip for fuel control.

I will post more when I am really back online. Like I said give me another week or so to have my T1 in and I will be good to go.

Mark, those are some great numbers! Congratulations!

HI!... SKID : So with a 5.4 making 260H.P (flywheel) and a SUPERCHIP adding 28H.P (flywheel). That would be roughly 288H.P (flywheel). So take off the generalized loss of 65H.P (flywheel) through the drivetrain and you get a RWH.P of 223. Now you made 350RWH.P in stock ATI form. So that's a gain of 127RWH.P with just the ATI. Not bad. Is there anyway you can post a dyno graph of your dyno run, and mabey crash or someone else can pst a similar dyno graph for the MAGNACHARGER. I'm just curious to see where the power starts and builds to finish on both kits. Thanks.

Do you (skid) or Crash! have dyno results of an ATI on a 4.6L? Those numbers you have are real good. Can't wait to see what you'll have with all your "trix"!

I'm interested

I would be interested to get bigger injectors, chip, (junk the FMU) and a big mouth MAF and TB too. Skid/Crash!: I'd be interested in knowing how much this would all cost prior to the trix kit ya'll plan to release this summer.

Skid is right about running out of fuel up top.

The plan is to use a Pro-M MAF and 42# injectors. Then remove both fule pumps and replace with one intank pump with about a 120 rating. We will generate a code to remove the FMU so the system will not have as many parts and we can use the code to produce our fuel air numbers. This will be developed and sold as a package (chip-burn, fuel pump, injectors, MAF, instructions) this way you will get a calibrated kit that will produce some numbers. We do not need to replace the throttle body (very low bang for the buck) as we are forcing air into the intake. If it was a N/A motor then yes but since we have positive pressure instead of negative pressure it will not help out. I am also getting a package together for Rods and Pistons for those who want to push the boost limit. Stock anything over 12 psi is not recommended unless you are looking to buy a new motor. With the pistons and rods I am getting together you can boost until your hearts content.

Exactly!

That's exactly what I'm looking for. I also think a good in-tank pump would be spectacular! Yes! AS for the 12 PSI, can you guys also calibrate the tuning kit with a 12 PSI pulley (either lower or upper)? I'd like to just get to 12 PSI. Plus, a flip chip would be great, so I can get better gas milage in-town. (i'd guess you'd sell a calibrated kit that could accomodate up to 12 PSI, in terms of fuel pump capability)

Regarding your trix product, will it allow me to get better performance for up to 12 PSI?

I'm glad you guys are thinking about this.

On another note, does your superchip give you more power and performance in the 2k - 3k zone?

PS - Do you work up in Plano at EDS?

Everything we propose will add performance and reliablility. The products we offer the push the limit we will let people know the specs and what to expect. NO not EDS. I am a computer geek though. I am a consultant. I mostly do fortune 500 companies. I am considered a network architect and engineer.

For all the techies I am as follows

MCSE (3.51, 4.0, 2000), MCT, CCIE (yes IE), NCDDS (nortel),CNA, A+, N+, Mouse

Started as a greece monkey, went to a custom shop (we did everything from leather to stereos to sunroofs to custom paint)

This is where I learned most of my stuff. Always loved bikes and going fast. Bikes are cheaper to make go fast. My current funny bike is about $100,000 and pulls a 6.89 at 213. to make a car that fast will cost tripple. Anyway all things on the bike cross over to the cars (they are all air pumps).

Tunned Kit

Ya'll I am getting excited and eager for a tunned, calibrated kit to run up to 12 psi w/o FMU!!! Plus I think a flip chip for towing and racing would be cool!!! Mark - have ya'll assembled the components and tested on your truck yet? Since your truck is more like mine (big, auto, slepper-esque) i'd be interested...

Also, are you getting a specially calib'd MAF or just a big'n and letting the chip code do all the pw stuff?

(sorry if i've seemed MIA too - i've been both busy AND about half the replys i submeit here get nuked b/c of this stupid laptop. dont ask...)

these will be tested in the near future on my truck. As of yet they have not. We are planning and conferencing other tuners in before we purchase the different products. Dont want to spend 300 on a part that will not work. Even worse break parts on the screw. Like I said this will be a 12psi no FMU everyday driver good for about 450hp.

Skid, you mentioned getting new pistons and rods. Will this be necessary for 12psi? Will your truck's chassis and drivetrain be able to handle daily use with 450hp? Are you planning on reinforcing parts of the frame, adding traction bars, or anything of that sort? Congratulations, though, on those numbers. Can't wait to see what the future holds.

Pistons and Rods are for those who want to go beond the 12psi mark. The chassis will take it. It is not like all 450 are stampeading the ground at once. Traction bars are a must if you want to hook at all with street tires. The 4r70w by itself cannot hold the power but with a baumann upgrade it can. 130 is cheap insurance on the tranny.

Will the use of traction bars effect the trucks ability to corner? I haven't even been to the track YET but if they help to hook and don't effect high speed cornering then I am thinking of eventually getting them later. As soon as the warranty is up the supercharger will be ordered. Keep up the great work. It's exciting to read the weekly progress you guys are making.

HI!... I've been running my "HPP" (holeshot performance products) traction bars for about 6 months now. I have them set wit 1/2 - 3/4 inch clearance between the spring eyelet and the snubber. The ride is a bit stiffer but when you jump on it, does it ever hook! Handeling was uneffected. If anything it feels better in the corners.
