just bought one today just wondering what you usualy see with a pretty much stock lt-1 thanks guys

 

Might be as much as 10 rwhp increase over stock. The only difference I really noticed was the hissing sound it made over the stock box.

 

couldnt tell you how much i gained horse power wise but it didnt feel like i gained much at all at first but as a few days went buy i did notice that it never pulled that hard before with the K&N and a cut out i went from a 15.1 to a 13.9 but it had a mass air, now K&N has a dyno chart on there web site and it showed a 17 horse power gain and i would say that is pretty close

 

wow so it is a good mod then...ya i have alot of suspention mods but not many engine just a cut out and the fipk haha awsome im excited then

 

sounds like you learned to drive your car too. 15.1 yikes

 

Well it wasnt my first time at the drag strip but that was when i first got the car it was bone stock it had some problems with it too but after two fuel pumps mass air flow meters new plugs wires all regular mantaince then i went back to the track and thats when it ran a 13.9

 

yes it is a great mod another mod you should do is a 160 thermo and a manual fan switch it just made my car respond so much better and just over all the car ran much better

 

awsome thanks for the input man, ya i got a hooker cat back and a 2800 stall coming soon thats my mod budget for the year...and i'll prob have to geta tranny cooler too haha but ya thanks again

 

I documented 12 rwhp gain on my LT1 and a 10 rwhp gain on my C5.

 

I haven't hit the dyno since the install but at the track I picked up 1 mph and 2 tenths. The throttle response seems a lot better also.

 

I wonder how these HP gains compare to just throwing a K&N filter in the stock box.
I know a couple different people with late model grandprix's that swear they could feel a good gain from just buying a K&N filter for their cars.

 

I didn't notice a gain until I had a few bolt on items put on, headers, cai, catback, new ignition coil, hypertech ppm 3. When they were all on I started to FEEL the car had more *****, firmer shifts are a definite plus also.

 

would the camaro ss ram air box+ ss hood gain anymore hp than that or same thing?

 

Many people say that the K&N FIPK or other similar CAI are actually slightly better than the SS setup. The air takes a pretty long curvy route to get to the throttle body with the SS setup. I doubt the difference is very much though.

I've always counted on 5-7 rwhp from the K&N FIPK, or similar.

this is a lil off topic, but i figured i would try to help another fbody enthusiast out. instead of paying for the catback( which is gonna cost 350+ labor) i would buy some longtubes and ypipe. reason being, is that u already have the cutout, which is the poor mans catback. so y get another. do longtubes and i bet u will be much more happier!
i honestly kinda like the sound of the longtubes through the stock muffler. but i enjoy it through the cutout alot more.
