Thanks it's the 1500 head unit with 3.75 pulley.... I will be upgrading to the 2200 unit. Also plan on building the short lock eventually
Next step is pistons rods etc also do the clutch while motor is out and the 2200 head unit , also waiting to see what comes out for more fuel ⛽️.... I notice after one pass I do lose power ... not sure if it's because of the 1500 unit or clutch slipping. But other than that I have done over 100 full throttle pulls on it and no issues so far

I want to go to the 2200 also but I too am waiting on a different low pressure system solution.

You should get a dashlogic so you can monitor rail pressure. If you don't have your IAT broken out after your meth nozzles then the car is pulling timing after your first pass because the IAT is before the meth and it's hot. Highway pulls allow things to cool down quicker cause the car is moving and air is across the intercooler.

Kosta, what all do you have done so far? I'm going down the same route, also on a stock short block. Do you have a bigger cam or ported heads installed? I assume you have full Z06 fuel setup (HPFP, rails, injectors?)

Thank you for that! I see exactly what he did for the fuel system there, make sense. You've got pretty much the exact same set up I'm looking to do, with the exception of the cam kit. I'm curious how high I can go with everything except that.

900rwhp out of a 1500 is insane.. usually they do good to max out at 830 ish. You have something right, that's for sure. Good job!
Yeah the fuels systems on these cars suck. Too bad it's not traditional port FI.
