Who is running aftermarket cams in thier 2.4's ? What gains & make ? Your personal opinion on thier performance would also be good . I searched and did not find any threads on this . If there is "bump" it up if not please post . Thanks .

 

there may be one guy on here running cams but not that great of a gain. Also the exhaust cam off the LNF is supposed to fit the LE5 if you plan on running boost.

 

The one guy I saw was running 14.1 with the cams...

...I'll take it

Jbody performance sells them...and they ain't cheap but you gotta pay to play

 

lol aint cheap aint the word for it. Although I heard they make something like a 20 whp diff.

 

everyone i know that has jbp cams says they blow ass, the car makes the same amount of power, everything is just ****** up in the power band

 

So you know people with cammed LE5's?


OoooOOOoooOOOoo...I would like more confessionals...


To the OP, PM G5Mike...he used to have them in his G5 GT

 

I beleive that he was talking about the LSj's aswell. A few of them have had nothing but promblems since they installed the JBP cams. G5Mike never really ever posted any real numbers proving any gains from the cams since he had no before and after dyno's.

 

Really?

Damn...not like I was going to get them anyways but you think they have problems from improper install?

Seems like everyone has problems with jbp stuff but they don't get it put in right...I dunno...I am a downpipe and HPT away from being done with my car so I kinda just stopped looking into more complicated mods(even though those JBP heads look ******* SWEEEET)

 

I thought i read the problems they were having were either due to the upgraded vavles or vavle springs that most did with the cams. Mike said he absolultey loved the cams. And the guy from out in Cali dyoned 203whp with I/H/E/DP/T/Cams running 14.1 @ 100 w/DR's.

 

talk to G5mike, he put cams in his 2.4, it was a nightmare at first for tuning

 

yessir i was speaking of the lsj's. but regardless i never hear anything good about jbp,....at all

 

It just seems that everyone the has used JBP cams have had one promblem after another, even if it was as simple as getting new valve springs. But why are they selling these cams claiming stock valve spring work then the car breaks then be like "Oh you might need some valve springs". I have heard some people say they like them only after the fix all the little things first.

 

Well from the two who i know of have them were mike, who first had a buddy mess up his timming on the install and cracked some valves having him to get his head re-worked with +1 mm vavles. After the install they discovered a rocker was cracked (which has been reported on a few stock 2.4's). After that mike loved them. And the guy i mentioned above has mentioned any negative things about them. Who else do you know that has them?

 

IMO not enough people own cams for there to be a hard answer either way...

 

I read about G5 mike and the other that was putting down 203 hp I am hopping they will post here with thier thoughts and experiences and maybe there are some others that will post can only hope .

 

IMO it is not worth installing new cams without pulling the head. Everything always needs to match what your final target is.
I would rework the head at the same time. Port + polish, stainless valves, new retainers + keepers, new valve springs that match the cam and desired rpm powerband + redline. All of this has to be done with thought to the bottom end as well.
I dont know why people these days try to rate things like pistons, rods and cranks to a certain horse power. All of those items are dependant on what RPM you want to run and you must match with your cam and timing components.

 

Some of the best info in this thread, Bravo
Spinning a engine past 7400+ RPM's things might not be yp to the kinda of stress.

 

Good post!!! I did indeed have my head redone at the same time,I did indeed enjoy the extra power I got from the head and cams,had a slight off idle at a standstill but had the car reflashed and it took care of that.

 

all of which i plan to do this winter, but im having trouble finding where i can get most of the stuff besides the cams(obv)

 

JBP has heads.

I want head.

For my car of course...they have different degrees of builds too it is pretty sweet...
