Dyno Pull 347/Meth PiMPxs

[arayaracing]

Posted above is the link to the final dyno pull after a good tuning session on the PiMPxs.  I continue to be impressed with the capabilities of the PiMPxs.  Here you have your average LX mustang.  Nothing fancy just a really good combination of parts.  730 HP/650 TQ with 91 octane pump gas with Methanol Injection. 
The basics on the engine combo are as follows:

     Dart based 347 (4.125"x3.25") 9.5:1 CR (Pump gas)
     TFS twisted wedge heads with 185 cnc ports
     Custom Bullet Racing Hyd roller cam spec'd for smooth idle and boost with a target power band of 1500-6250.
     Edelbrock Performer RPMII intake manifold
     #80 lb fuel injectors
     Paxton NOVI-2000 at 20 psi of boost, non-intercooled
     1 3/4" short tube headers with 2.5" exhaust system with very quiet DynoMax Super Turbo mufflers and tail pipes.
     Methanol Injection Kit shooting 100% VP M1 uncut.

Here is the wonderful part of the PiMPxs' capabilities.  I run 2 of the largest nozzles offered by the Methanol Injection kit, I spray one before the blower and one after the throttle body.  I use the PiMPxs to control when the meth comes on.  At first I had it on PMW and was fogging it in as soon as boost hit 5 psi.  I was having trouble when the Meth would start to enrich the AFR to 9.8:1 and causing a huge dip in HP.  I switch the Meth to an on/off circuit and I would just turn on the Meth pump at 10 psi, with so much meth running through the engine and fuel the car was difficult to tune.  I made several pulls trying different tuning options, when I finally got it.  I would almost turn off the fuel injectors at the exact same time the Meth would begin to inject.  The results were astronomical over 700 rear wheel horsepower.  I logged a 90 degree drop in air charge temperature, which I took advantage of and started adding timing back in to it.  By the time the tune was completed it made 730 RWHP and 650 RWTQ.  That made the car Blown-Injected-On-Alcohol!

Thanks for all the support and thanks for making a product that actually works, and works well!  Best Bang for the Buck!

That's getting it done for sure!

The Super Turbo mufflers are likely costing it significant power (like 30-50hp) but if the customer likes the sound/lack of sound then they may be fine with that.

Another option if you wanted to use the ECU for a progressive meth injection setup you could control the pump with a solid state relay via PWM (pulse width modulation) which would allow you to give it for example 30% flow initially and then ramp it up with RPM until it was at a high enough RPM that it could handle full flow with "normal" gas fueling/ve table values.

I had an Anderson PMS and a killer Pro-M mass air sensor prior to the PiMPxs upgrade. I made 650 RWHP on straight pump gas with the PMS, which matched up with the 650 RWHP I made with the PiMPxs.
The biggest difference is in the street tune, the everyday stop and go driving is flawless. Below 90 kpa I have it running stoich, 14.7:1 and it idles at 750 rpm. Fuel mileage is up! Fan control is on point and it also is the controller for the meth pump.
This is by far the best tuning hardware with the easiest tuning software, its very user friendly.
I have two more buddies that have 2.3T vehicles they just got into cheap, of course because they have blown head gaskets and a string of bolt-ons. They already reached out to me for assistance. I gave them your web address and told them what they need to buy. Once they receive it, I'll be tuning them. Keep up the great work.

Would love to see your timing table !

I have a very similar set-up, 366ci with si-trim at 15 psi. pump gas with meth.

Car went a best of 9.80 at 138 on the 1/4 at 3200 lbs,street car also.

I have a very similar setup and I am trying to get the tune right for WOT. What AFR did you end up with at WOT?

You should be targeting 11.5-11.8 at WOT and high boost.
