I know zero on tuning the gen V engines. Thanks for the quick overview. Love the channel.

[@davidciesielski8251]

Wow!!! Thanks for the lesson !!! You really have a way of making sense out of ALL this

[@strictlyg8power98]

Great video. I always learn something about the tuning process watching your videos. Thanks again for the tour this week. My son really enjoyed the visit too!!

[@ApeMotorsports]

Happy to have you guys as customers. We'll be pulling the engine on the G8 next week.

Will Holley Terminator X Max Work With Port Injection?

[@ANMIV517]

Matt do you know any shops in FL that are competent?

[@MH-ce2io]

Any insight on how system compensates for added air during pulley change? You mentioned that he could swap pulleys back and forth without a tune?

[@ApeMotorsports]

Mass air flow sensor. A smaller pulley draws in more air which the maf reads and the ecm adds the appropriate amount of fuel. Since the port controller is also maf based, it too will adjust fuel on the port injectors.

Hey Matt, how much timing would you run on a ZL1 with magy 2650, 2inch headers, Port injection E85, 85mm upper, RF Big gulp, with stock heads and cam.

[@ApeMotorsports]

23-25 depending on if you have cats or not. Assuming boost in the 15-16 range at peak.

[@hookedandcooked2041]

@@ApeMotorsports thanks for the reply! 16# boost as you said and no cats.

[@jeffnoob8448]

What size injectors? Beautiful build

[@ApeMotorsports]

DI injectors are stock LT4 and the port injectors are 80 lb/hr.

[@DigitalCourseDetective]

at what point do you think we should look to build the 10spd trans?

[@ApeMotorsports]

Once you are over 1000 rwhp the reliability starts to drop off on a stock 10 speed.

[@DigitalCourseDetective]

@@ApeMotorsports so I’m at a 6-7k elevation our DA is typically 8-10k…I only feel 850whp due to correction factor…so am I still in the safe zone? I make 1078whp SAE

Hey Matt, I have a 6th ZL1 1LE with magnuson 2650, 85mm upper, stock lower, toohighpsi port injection for fueling. Can you tell me how fast are your customers 60-130 times are with similar mod? Mine doesn't seem to be running at max potential.

[@ApeMotorsports]

Does it have headers? What intake and throttle body? What fuel are you running?

[@hookedandcooked2041]

@@ApeMotorsports yes, 2 inch headers and full E85

[@hookedandcooked2041]

@@ApeMotorsports 103 TB as well

[@hookedandcooked2041]

Rotofab big gulp as well. What time of timing do you usually have this type of set up running? Mine is currently running at 17.5 degree at WOT and I feel like it should be able to do more for a magnson 2650, port injection, rotofab big gulp, 85mm upper, 2 inch headers. Stock cam,heads, and lower pulley.

[@ApeMotorsports]

What fuel?

[@andrewg.2165]

Where is your shop at?

[@ApeMotorsports]

Loves Park, Illinois.

[@gbass7328]

Good work! Stock clutch?

[@ApeMotorsports]

McLeod rst. The stock clutch would hold that for a little while, but he races it and wanted something that would hold up over time.

[@gbass7328]

Makes sense. Really like your approach and engineering.

[@jackstoepfer1494]

Did you do the triple pump just because or is it needed w under 1k wheel? Fore numbers said dual pump kit supports 1k wheel on e85. I was hoping to see your low side fuel pressure on the log

[@ApeMotorsports]

The triple is not needed at this power level. For a little more money it future proofs the system if more power is ever wanted later with a built engine. Base pressure is set to 60 psi. The regulator adds 1 psi per pound of boost on top of that.

[@jackstoepfer1494]

⁠@@ApeMotorsports do you remote tune? I’m about to install the same port system on my turbo Camaro.

[@Vazriel89]

Ditto, I’d be interested in a remote tune with an almost exact build

[@ThemotivatorZL1]

Where is your location???

[@ApeMotorsports]

Nickey Performance is in Loves Park Illinois. I have since moved to Madison Wisconsin and am working at a different shop.
