How can i get some simple horse power form my original IDI? 95,000 mile truck, I already have some ideas, stage 2 injectors, K&N air filter, 3in Straight pipe. Any more ideas fellas?

 

go get some bigger exhaust.... get rid of the clunker for an air cleaner..(scrap it)... get a 14" k7n thats 6" high.... and switch to royal purple 15/40 synthetic... get ya some z-max and some lucas Full synthetic oil stabilizer.....I gained 1.3 mpg's just changin oil ... I run it 10,000 between changes... it willl go longer but thats about twice a year or so...

As for exhaust I'm running dynomax and its 4"... primarys are 2.5 into a 3 to a 3.5 to a 4" in to muffler.....

WARNING... the k&n will make it loud in the cab... but it sounds great.... try some dyna-mat or something like that ... will help too.. I love the sound it makes....... check out my pics... will add some soon ..... she's a beautiful truck... just need more lovin...

Get a turbo

 

I'll try to get one. but im thinkin a 6.9 air cleaner is what i need for the air filter, cause no block and soup bowl, Block the little peice of metal right after the hose hooks to the body,on the inside of the air cleaner.

 

if u go turbo make sure your heads are on good..... dont wanna go over about 6 psi... top's...... unless you want to be doing a search for your heads and pistons...

 

I've pushed 17-18psi on 21 yr old gaskets and head bolts. Cruise at 6psi on freeway. 15 seems to be the red zone tho from what others say

 

12-15 psi max is what most say and follow. not sure where you got 6 from. the stock setups run 10 psi stock.

 

oh i keep being told 6 from international dealership.... must be a safty thing... I'm never 100% about that number... I'm sure on a hard pull 10 would be good.. but 17 seems kind high.... I havent had much opertunity to pull heads on these motors just been other external stuff..... I would think that 350-400 hp would be do-able.... I work on old detroit's and they have 400 or more...
