FSP - 1291whp, And Counting...Addition of Haltech Standalone EMS + Port Injection
Well guys we have found the limits of injection window for the C7/DI motors.. We have made 1291whp through Motohead429's C7 at just short of 6300RPM. We just do not have the window of time to get the injection completed (Yes it does not matter if we step up more injector, etc.). So we have turned to Haltech for the additional engine management to cover a few aspects of the build.
The Haltech Elite 2500 Engine Management System
will be coupled with the factory ECU for complete "like stock" operation of dash and creature comforts.
The Haltech brings to the table the following new aspects:
- All ignition timing
- Port Injection Fueling (Stock ECU controls DI)
- Haltech Engine Protection - Protection for Lean Conditions, Low Oil Pressure, Fuel Pressure, EGTs
- Exhaust Gas Temperature Probes, Individual to all 8 Cylinders. This allows individual cylinder tuning for maximum performance, also coupled with the Haltech Engine Protection system.
- Addition of Haltech Race Traction Control Management (Basically put your foot into the throttle and let the traction control handle all aspects of management, this is especially helpful for street & half mile)
- DBW Idle Control
The vehicle details are as follows:
2014 Corvette, Widebody Z06
Powertrain
- LME 416ci, Callies Magnum/Ultra Rods/Wiseco Custom Pistons - 10.5:1, LME Ported CNC LTx Cylinder Heads, BTR Trunions/ValveSpring Kit, FSP Custom Cam by Comp Cams 235/248 118LSA
- LME Billet LTx Intake Manifold w/ LME Billet Rails (Only production one in existence for testing)
- ARH 2" LT Headers w/ 3x3 X-Pipe , Corsa Xtreme
- FSP C7 Breather/PCV System
Engine Management
- Haltech Elite 2500 Engine Management System
- Haltech 8x Individual Cylinder Exhaust Gas Temperature Probes
- Haltech Dual Analog Wideband System
- Haltech CAN Bus System
- FSP Custom Adapter / Tone Ring Setup for Front Wheel Speed (For Haltech Traction Control)
Fuel System
- FSP Custom Secondary Fuel System including DW 1500cc Injectors, Fuel lab Prodigy 1500HP Pump/Regulator, Custom Fuel Lines for E85
- Alky Control Triple Nozzle Methanol System (Dropping back to 2 Nozzles)
- Factory Fuel System in place for control of GDI.
- E85 Pump for Street/ C85 for Track Use
- Procharger F1X, 4.0" Upper, Innovators West Balancer, 8.3" Balancer Ring
Drivetrain/Suspension
- Mantic Triple 9000 Clutch Kit w/ Mantic Custom Flywheel
- DSS Level 5 Axles
- LG Motorsports Bilstein Coilover Kit
Made 1291whp at 6290RPM, on 26psi with stock ECU.

Before Port Injection...
Moving coils to the fenders...
Flex fuel sensor that is split signal to E92 factory ECU and Haltech 2500

Oh I'm firing that thing off about 455* before BTDC in the upper RPM range... LOL... I'll grab a screenshot of it later on, just way hectic here today after we were tuning in Houston all last week for TX2K.

I assumed it was atleast 430 lol
I've done some Vortech setups and put them around 420s
I'm sure you are busy.. Thanks for sharing much detail about the build....

You running the halltech box in open loop fueling only I assume keeping all closed loop control DI??
Halltech box sounds really nice with its abilities... I assume you can adjust injector pulse width based map pressure or other variables?

Finally a solution for the fuelling! 
Well done to all involved and look forward to seeing the final results. Quick question, any plans for a standalone fuel cell for the port injection? Also does the stock fuel system handle 100% fuel delivery when at low load?

chuntington: Right now we are using the stock cells.. We want the same fuel supply for both systems considering we are flex fuel now and the flex fuel sensor is on the return side of the "standalone" injection system, but that pump is always moving fuel so we have the same composition % between the two... Yes it's confusing.

Yes it's confusing.
It would be nice to see an 'octane on demand' type solution with a second fuel cell. Then you could bring in the port injection with boost and maybe even take out some of the DI fuel flow. Obviously this makes things MUCH more complex but does get you whatever octane / fuel you want whilst still using normal pump for the low load stuff.

Also if you wanted to go nuts you could mount a 3rd set of injectors firing Down the intake trumpets. I have seen some testing in which people got more power with the injectors mounted father out. This was on 4cylinders but the same applys. The tests I saw had the second set of injectors about 12inch from the primary's! The intake looked daft but it made more power and torque and, as it was a race car, that's all they were bothered about! Lol
Obviously that would mean cutting up the lovely intake though.

chuntington: Please do not give our client or us anymore ideas for this project... We just keep going OOH look we can do this too... Car is back running with the PWM Fuel Lab pump controlled by the Haltech, we fired off the port injectors at idle and all is well so far.
