SLP V6 1.8 rocker arm package

[JAM]

From my understanding Ironman is correct. Higher ratio rockers are just to give you a slight lift and slight hp increase IF you don't want to go thru the labor of putting a cam in.

I think if you skip the cam and go for rockers. I would use the intense racing full aluminum roller rockers at a 1.9:1 ratio. Should go all out if your gonna pay 400+ smacks for rockers. LOL :D

IMO these rockers and pushrods are great sounding, however the price is a little steep however the HP gain is great. When I read the article in the magazine, it pissed me off to find out that this guy had headers, intake and these roller rocker arms and pushrods installed then had it dyno'd and it only HAD A FOCKING 193 HP!~ :eek: [img]graemlins/omg.gif[/img] [img]graemlins/bs.gif[/img] I thought our cars came stock with 200! WTF?

[Boehlke]

At the wheels man, at the wheels. Figure in about a 15-20% drivetrain loss and you'll come up with almost 240 flywheel hp. 40 hp over stock isn't bad at all.

WHAT?

[12secondv6]

Sooooo, what do you all think of them??
10 HP is 10 HP, that is a great gain in a v6 which is DYNO proven!!
Some say $550 for 10 HP is a waste, well, how much did we all pay for headers???
$450? and do you really think we actually saw 10 RWHP?
I don't.

At $549.50 for a V6 does this mean that they would charge $732.50 for the same set-up on a V8? (We only need 12 versus 16 for a V8)

I'd love to get them myself but the price is wayy steep. I'd consider them for maybe $300.00 - $350.00. At that price I guarantee you that SLP would sell a lot more and still make a nice, fat profit. I don't think that they (SLP) realizes that V6 owners don't have the fat checkbooks that the SS/Firehawk guys have.

As far as comparing the price/benefit to a cat-back, with the cat-back you also get sound and looks to go along with the 10 hp so they really aren't comparable.

I'll agree it's alot of money, but there is another benefit other than 10hp - the wear and tear on your motor when you're at higher rpm. That GM High Tech article said you save about 408 grams (don't have article in front of me) or about the weight of a piston off your rockers. Anytime you lighten the load on the valve train it's a good thing and makes it easier for the valvesprings to control the motion (valve float, etc). Maybe it doesn't add the most HP, but maybe it'll make it easier on your motor when you throw that 100 shot at it.

Would this be my first mod? No, I think you'd get a better bang for your buck with a HPPIII or something because you can mess with shifts, coolant temp and tuning. But after you've put quite a few mods on it might be the next step - depends if you're going for all out performance or you think the stereo is more important.

Boehlke - If you have stock ratio rockers with your hardened pushrods, you may have to think about different pushrods anyway with the increased ratio of the SLP's - it could throw off your rocker arm geometry enough to need a different length (Anybody feel free to correct me..)

As they say though, Don't kill the messenger. Tom didn't set the price on the rockers. Sounds like he's just trying to offer a good selection for us.

I agree with James.. I might have seen 12 hp with the headers catco and 3inch flowmaster exaust.. That was close to 1,000 dollars right there.. The new rockers with a nice cam and ported heads... what a combo..

[Dominic]

Overall its a good mod, but its better for some than others [img]smile.gif[/img]

Thanks Tom for providing it to us from SLP and adding as much information about the product as you could!

[JAM]

Would this modification work with a Hypertech PP3 high octane setting? I know the Hypertech advances the timing. Will adding in these 1.8 ratio rockers be ok to use? Will it make more power with the hypertech stock vs the hypetech 1.8 set up?

Someone mentioned earlier that you might need different pushrods. It says on SLP's web-site that you get new pushrods. ;)

Jam - I only mentioned possibly needing new pushrods to Boehlke because he already had new pushrods and wanted to just buy the rockers seperately. Different rocker ratios may throw off your geometry enough to need shorter/longer pushrods. The pushrods you get with the SLP rockers should be right for that application.

Ok. Now that we cleared that up will the Hypertech PP3 advance timing, and higher octane work with this 1.8:1 ratio rocker set up?

[AllTheGoodNamesAreGone]

Ok, here is my .02.. I think the slp kit is not unreasonable.. I would stay away from the intense kit.. I talked to their reps and found that the were not to helpfull.. nor willing to offer too much information on their aluminum roller rocker kit.. but they do offer modified stock rockers for $330 (+$50) core.. the sound great in theory (about 13hp maybe more).. but i cant feal good buying used parts for that kind of money.. So! that makes the SLP kit a little more acceptable.. they are $530 at tbryne.. so thats a litle less then SLP's price.. However.. I would like to see someone take up a group purchase on this one.. I for one would be IN on the SLP kit.. I dont know how to get something like this started but its jsut an idea..

later

I would be in too!!

[AllTheGoodNamesAreGone]

Yeah.. i dunno.. $330 gets you more power.. but.. i would be 100X more comfertable with the slp kit.. intense motorsports is shady as hell.. but.. $530+ is way to steep IMHO for the slp kit.. so.. its a toss up.. I really cant decide.. if the slp kit was sub 500 i would definantly be willing to give it a shot.. and do some dyno testing to see my gains.. ohh well.. maybe i will just "wait a while"-&gt;(lol.. just like school work)...
