I'm going to be upgrading my valve springs in a few weeks, and I just happen to have some ZZP stage 2 cams laying around to throw in while I'm at it. I have the 6758 ZFR turbo, for now and run E47, and so the added fueling will do me well. I havent heard anyone talk much about these cams. Anyone have them in that wants to give some feedback, I would love to hear.

id also like to know what gains u get with these

Are you going from stage 1 to stage 2, or stock to stage 2?

cw383

iTrader: (6)

Sorry Sam, I'm afraid of that beast you have! But yeah, I'm game for some runs. 96S1, I'm still on stock valve train. I thought it a shame to pull the cams out when I add in my springs and not have something fun to replace them with. 09CobaltSS1 ( John ) has my car flying on an E47 tune with room to grow, so why not. I may be testing the stock short block limitations, but I dont hammer on it all the time, so I may be ok for awhile. Might be time to start talking to Mongo about a built short block.

I have the cams and updated springs e 85 pump was running out of fuel before cams on terminator tune haven't got back to dyno yet they are not fun to idle around with very jerky in third 4th and 5th below 40 mph ??? also have the zfr turbo

Hopefully my soon to be 4.45 gearing will remedy that. Are you still on the 3.82's, and did it wake the car up much under boost? Thanks for reply

stock block wont last long on s2 cams and zfr with e85 lol. ill be running a 2.1 built block, pnp head with s2 cams this spring. hoping for just a little more than 500whp. going for that LNF record with those 4.45 gears lol.

With a proper tune and driving habits a stock block will last just fine.

PrincessTurbo

No it won't.. Whats the purpose of putting it on your car just to " detune " it ? Just to say you have it?

I'm sure a lot of engines would last a few pulls, you change the cams in these cars you're pretty much asking for it with a stock bottom end. I really don't care how light weight your foot is either. Thats horse ****.

Explain how adding cams alone makes or breaks your bottom end

These motors are not made of glass. There is no reason a little ZFR should be doing these motors in on any reasonable boost level. The cams will add some power, but the main benefit is how aggressive they allow you to get with the fueling. Hell even my friend's LNF on stage 1 cams on E85 on a s259et makes 480whp on stock block and has for 2 years now, and 430whp for 2 years before that, and that car has been through more "Mexico runs" than most LNF's out there.

Cams won't break anything unless ur making more hp than the internals can handle. If ur only making 400-450 with stage 2 cams in there it will last just as long as 400-450 without cams.

raver0789

Stock bottom end will do 500whp. Everyday. With a good tune. Proper fueling and a large enough turbo.

KonnerTomlinson

emphasis on the good tune part

dcrep06

while close to 500whp may last on some, i bet it wont on most.......i know there are some out there but there have been way more than break on lower power. s2 cams and e85 on a bigger turbo is pushing it, whether you want to admit it or not. no matter who the tune is done by or how its tuned. lets be honest here........never said people havent, cuz some of them have freak motors, but for the majority speaking, it wont last long.

Bluelightning

iTrader: (8)

A large majority of the motors blown on this forum haven't been from too much power. Just because you see them break making less doesn't mean that's all it can take. Id have to disagree, a HUGE part of a motor surviving is all in the tune. The motors you see survive arent "freak" motors....

Olybaltss

you mean there's no chance i have a magic LSJ that's more powerful and stronger by default than other LSJs made to the exact same specs? Darn.. (lol)

Sub'd for more info.

I'm the most powerful ZFR 4.45 on that list right now (#6) on stock cams, injectors and LPFP.
My next performance upgrade will be stage 1 or 2 cams, Opel injectors and AEM E85 LPFP.
That record is mine

ya but you're using E and I'm #8 on pump gas, completely stock motor, with 4.45s. What now??!!

I am fully aware its a crap shoot. I do have plans for a built short block very soon, but that being said I'm sure I would cry like a baby when it does let go, lol. I will be sure to pull this thread back when that does happen, or if it doesn't. To be honest, if I can hit 440hp on cams, meth and E47 I will be happy. Don't want to set my expectations too high so I'm not disappointed. I feel that's a realistic doable goal. I'm going to wait till I get my trans and clutch in till I dream about a dyno, or letting Wert beat me me like a redheaded stepchild at the track

Wert842

iTrader: (3)

Lol. Don't be hating.

dcrep06

we will see :P lol. dyno numbers dont really mean much though, esp comparing a dynojet to a mustang dyno.

i was pump gas but wont be for long.

09CobaltSS1

Unless you run on an uber lower reading dyno, 440whp will be easily doable.

colodude18

iTrader: (4)

Oh there's no doubt that your numbers are impressive and I'm convinced that me running e47 is the only reason I'm making 34 more horses.
As for running on the stock engine, I probably would be still as well if I hadn't spun my bearings on stock turbo ;-)

lol I know it's only numbers on a piece of paper, but that's what these records are. Quite honestly I'll be doing those fueling upgrades for safety and not for more power. But that doesn't mean I won't do a few dyno runs just to see what she could do I'm only running 20psi at the road track anyways.
