I will know more once I get closer to the actual #'s .. should be about 400-425, but will be keeping it all in check and clean running..

 

7x12 is a big puppy to try to keep clean with a 12v! little easier for me

I just change the tune. great stick in my opinion (not for stock trucks)

 

Oh yeah .. I hear that .. the current 215 inj. are just too smokey and the EGT's can get hot quick ... so its gonna be a ton of stuff put on at once .. will tune from there ..

i may end up doing a cam to help a bit with spool and EGT's as well, Will run the new set up when I get it all here and installed and tune it for a bit .. then move forward from that position

 

You should beable to make over 400-425 on compounds with injectors and tuning etc. My buddies truck that I built made 405/847 on a 180 horse auto truck maxed fuel and tuning, bd special, htt manifold, 4 gsk only fueling to 3400, and crazy carls full intake piping from turbo to intake. Stock everything else, just installed 191 and should pick up another 20 horse or so and break 900 ft lbs.

 

A 7x12 is a hell of a lot bigger than the 215 injectors...

I ran industrial 150's and it was not uncommon to see 1500* on the pyro
Switched to cpp 7x0.014 sacs and lost a ton of smoke, spools twice as fast and on a hot day I can hit 1300, i have detuned the truck due to the dd factor, but it still runs good, I can hit about 1150 now no clue what the truck makes for numbers. But I refuse to dyno her till I'm certain it's over 750. Needs a couple things first like a real injection pump!

 

LOL... my engine is a 215 engine .. W/887 pump its a 96 manual engine in an auto 2wd truck .. single cab etc ..

400-425 is good .. much more and I will back it off .. safe parts that way

 

Why would you even bother with twins and injectors at that power level. You will barely be spinning the ht60 and will basically be running the whole set up choked back. A stock 215 injector and a 62/65/12 or 14 would yield the same power or more as well as be much cheaper and faster spooling. My buddies 405 on all stock and a bd special 64/71 is fairly quick spooling as it is and barely made a puff on the dyno. A 62/65 would have cleaned up even harder due to spool up.
