when doin this ISR mod...do u think it will better my gas mileage..??? the ISR mod or even the elbow removal or deckplate mod.??...

 

You should get better milage but even if you don't, it certainly won't go down and you will have slightly more power so there isin't anything to loose (except for a quite engine).

 

Deckplate is the most noticable of the the three mods you mention.
The ISR should be done with the deckplate and will noticeably add to your engine noise.

 

If you do the deckplate, don't pull the elbow. If you do, then when you WANT to close up the deckplate (water crossings) you'll still have a gaping hole in your airbox. Not good.

The ISR is meant to smooth out throttle response and (like Jamie said) won't do much unless you do the deckplate. Reason being that the engine is already "starved" for air with the elbow in place, so smoothing out the intake path will have negligible results.

Do the deckplate to get some more power (a dyno run I did shows 5hp), then do the ISR to get a smoother throttle response.

 

ok i might be doin that deckplate mod and the ISR but how loud will it be...engine noise wise...and will it give me better gas mileage..im tring to do stuff so that i can get better gas milage besides jess basic tuneups...

 

No, you will not get better mileage. Even if you did, it would be next to impossible to calculate the small difference.

If you are going from stock intake to deckplate + ISR, you are going to be astonished at the increase in sound at WOT. I would go deckplate first, get used to it, then go ISR mod. You can always put the deckplate in or reverse the ISR mod - that is the good news. It's a loud set-up.

 

just wondering what the ISR mod is and if there are any write-ups on it....thanks....

 

Check out the tech section. I even have a couple left if you want to do it and you have a 96/97. My write up has changed slightly since I submitted it to Corey, so I have an updated version (better).

In summary, it removes the factory intake silencers to smooth out the airflow and increase throttle response. Oh yeah, did I mention that this mod is LOUD with the deckplate open at WOT??
