What do stock TPI injectors flow? 19lb/hr?
Would it be beneficial to go ahead and buy a new set of 24lb/hr's with my current setup?
My setup

 

I believe 19 was for 5.0 and 21 were for 5.7. Someone will correct me if I am wrong. If you have an MAF setup, then it may be ok to upgrade to 24 if you adjust your fuel pressure to compensate but it would be better to burn a chip. I havent had tpi for awhile so I am a little foggy about it all.

 

The 350 stockers are 22 lbs/hr. I think you should be fine with 22's unless your pulling a lot of RPM's.

 

Hey raptor,how much did it cost you to buil your engine?

 

I think I'm going to go ahead with the 24's.
I'm figuring somewhere in the neighborhood of $100 plus shipping both ways plus packaging just to have them cleaned. I estimate about $150. Brand new Accel 24's are only $230 from Summit.
I think I'll keep these stock ones for cleaning at a later date to put on the other motor I'm building.

 

You should try slp performance,they usually have them for like 100 bucks

 

Into this myself. Note the Accel web site calls for the 21# injectors for Camaro L98, but 24# for the Vettes with same engine. Figure the better exhaust in the Vette makes for the higher flow. My 85 Vette had lower fuel pressure than the 88 Camaro too. I'm figuring the Accel 150823 set for mine, 23# injectors. With minor mods these should dial right in. Hard to believe these things are so expensive, but I suppose Bosch gets a royalty from each one.
