Enough Fuel Supply for S-Trim?

[caine0]

With using the T-rex that comes with the supercharger, and a Walbro 255LPH in tank fuel pump Part #GSS307, will I have any problems? I picked up the wrong fuel pump by accident. I guess the one for boosted applications is Walbro #GSS340.

Here is my setup:
302 Block
GT40 Irons
Trickflow Streetheat intake
Edelbrock 75mm Throttle Body
Pro-M MAF 80R
42lb injectors
S-Trim at about 10# of boost.

Will I be okay with the T-rex helping out, or do I really need to go pick up the #GSS340 and not use the T-Rex, and why? Thanks

Sorry about the double posting, but I need to know by tomorrow.

Should be ok. I have the GSS340 Pump and Inline setup which should be good for about 500rwhp.

The GSS340 is mainly to keep the pressure up at high rpms and high accelerations. Because you are using the T-Rex pump, that will be your aid in keeping the pressure and volume to it's max. Both pumps pump 255lph.

I would think you're good to go!

No matter what intank you choose I would use the T-rex also. I ran a 255HP intank with a T-rex on my S-trimmed 331 with 42# injectors and no FMU without any problems.

But for your combo, either pump should be fine with the T-rex...
