Adding sc to the tow truck /fueling question???

dbs1 · 11-16-2023, 06:49 PM

2018 Denalli 1500 w/6.2. Currently has tune, headers, 3.73 gears and a Tx Speed stage 1 cam (after the dod ate the cam).

Thinking of adding a Whipple 3.0 sc and wanting to make sure I’ve got the fueling covered. TxSpd says the cam has a 38% fuel lobe. Rwhp should be 650-675.

Anyone know if this would have enough fueling capacity to not have a problem?

Is it an LT4 or LT1 engine? If it's LT4, the stock fuel pump should handle all that but you would probably want to throw a JMS on it or something the likes if you want to handle E85 on it.

The engine in your truck is basically like a LT1 in a Camaro SS. Pump gas isn't ideal with boost but your cam will help. Fueling is going to depend entirely on how much boost you plan to run which won't be much imo. 7-8psi tops and that isn't really utilizing the Whipple 3.0. You would be better off to go with a LT4 supercharger at that boost level.

I don't believe GM put LT4's in any trucks...the 2018 truck 6.2 is a L86 similar to the LT1.

I think the injectors and HPFP will need to be upgraded. Maybe King can chime back in but I swore the L86 fueling was even smaller than LT1 fueling.

You are correct the trucks have smaller in injectors than the Camaro LT1

This gentleman will need an LT4 pump and injectors.

And We stock them.
