does anyone make an solid rocker assembly for a ls? i'm movin on from the 600+whp stock sleeve ls to try to throw down some serious numbers in sfwd trim... i know this section isnt for boost motors but i figured the all motor guys would know a better place to find a solid rocker assembly for a ls.

i just wanna rev my **** higher than 8500-9k without losin a rocker.

 

I'd imagine it would be hard to find something like this that is cheaper than switching to a B VTEC head. Does the LS head have the same capability for flow as the B VTEC?

 

not without allot of $$ for larger valves and lots of port work.

to the OP: the rocker arms failing have nothing to do with the amount of power the engine makes. the OEM rocker arms wont fall apart or wear at 600hp anymore than at 150hp. the rpm you want to run may have some issues. im sure they can handle 8000-8500rpm occasionally with the proper valve springs and retainers.

will you actually be making power up to 9000rpm? i would like to see that...even the most aggressive LS cams and crazy port work you might see some good power up to 8000-8500MAX. most will make peak power around 7200-7600rpm.

 

And therein lies the gem of ignorance.

 

Works for me.

 

the gem of ignorance eh? and whats the ignorance here? the fact my ls makes power that high? or maybe cause i've had good experiences with my setup and dont want to be on the trillion mile long bandwagon of people with ls/vtec?

here's my graph at 28psi and no spray. stock sleeve piston/rod, minor headwork ls boost motor. reving to 8k

 

mine makes peak power at the rev limiter.... 8k, i know its not power that makes the oe rockers pop out

ya with alot of work. got one head to do pretty well with some oversize valves and port work. i got some badass cams that we use as well. manley springs/retainers.

 

Your engine is boosted, and the graph I see isnt making power to 9k, the graph stops at 8k.

We get alot of people in here who post something like

"hay d0 I needz da value terrain, I only wantz to rev to sometin like , 10k, not dat high, lolz".

So we are a little trigger happy when it comes to stuff like this. If I was in your shoes, I would forget about caring if I was in a "bandwagon" or not, this isnt High School, and switch to a VTEC head. So what if a ton of people do it? Thats because it works, and you will have a much better valvetrain setup. Good luck.

 

it makes peak power at my rev limiter so it will make power higher. i haven't reved it to 9k because of losing rockers... im stickin with ls because its different. anybody can go out and makes badass power with a ls/vtec, hardly anyone does it with a ls.

 

^^^ What is this about for you, making power or being different?

Better yet, what is so special about a LS head that you would want to keep it inspite of several distinctive inferior characteristics (rocker arm ratio, flow, valve size, variable cams) relative to a b16 or gsr head?

 

I'd imagine that he has quite a bit of time and $ invested in the LS head. If he were to switch to B VTEC he would have to spend some more $$$$ without getting much back from the LS if it would sell.

 

Then he should be looking for custom parts ie roller rockers and cams. The rocker arm ratio and mass make that valve train unstable at high rpms.

The cost of custom roller rockers and cams > b vtec head, vt, Pro1s, and mild port work.

 

The cams that were using will make power past 9K, they were originally designed for N/A applications but we found out they work very well for boosted setups as well if you have the flow on the turbine/manifold side.. The reason for sticking with the LS is just because we can.. Plus we really havn't seen anyone do any really crazy setups with the complete LS setup so it'll be fun and a leanring experience trying to do what others have given up trying to do.. Its just a fun/challenge thing really. The issue we had back in the day with the N/A setups and these cams is with the notorious rockers poping out from underneath the cam problem.. They would make power past 9K but every so many passes we'd have to pop the rockers back in.. So I told sticks (c1v1c3x) to ask around and see if anyones come up with a roller rocker or solid rocker type asssembly for the LS head.. I figured there problably wasn't anything out there but it was worth a shot..

 

^^^says my tuner

 

It bears repeating

Is it about making power or being different?

The reason no one has developed a better valve actuation system for the LS heads is because there already is one. Its called a VTEC head. I understand your concerns about stability at high RPM, but ya gotta pay to play. I would imagine a substantial HP increase, especially on a boosted setup already making that much power. HP per $ from a VTEC head swap would probably beat out anything else you could do , ratio wise.

 

i guess since you're so stuck on getting an answer for me and those are my only options then it is about beig different. it is about stepping out of the norm of what anyone can do and doing what everyone says you can't. everyone told me i'd never be able to make over 600whp on a stock sleeve (otherwise fully built) b18a1... and i DID IT and the motor still runs better than ever with just as high of compression as the first day we started it. now i am out to bust some 9's with a full ls setup. because NO ONE has done it yet. and everyone says you can't. so yes it is about being different if you want to word it that way.

honda-tech has changed alot from back in the day. it used to be tech... now it's just "you cant do that, it's not possible" "do a built sleeved ls/vtec exactly like everyone else and slap a turbo on it. and BAM you're just like everyone else..."

thats not me im not everyone else. i like to try new things and will continue to do so until i find a comfortable setup that is DIFFERENT

 

Theres still plenty of tech on Honda Tech, you just have to search for it.

Good luck in your quest for powe,.... er, I mean, being different.

 

we're going to make them in house... check back with me in august for some time slips and dyno graphs

 

ok.

 

yes you made 500hp but hp is nothin without tq and your motor quit making tq at 7000rpm so why turn it 8000+rpm its pointless

 

maybe so when he shifts he wont fall out of his peak torque area.... even at 8k its much higher then 5k

 

he's racing sfwd, so he needs to turn the rpms so he can stay in 4th at the end of the track. you're limited in tire size, so gearing or turning it higher is just about the only way to go.

 

we're still running the cams at 0,0 also, theres ALOT of room to coax the power band around once we get the rocker setup figured out. Also its a very gradule drop in tq. I think the decline is slow enough to where it'll still continue to make power with more reving. When it drops off hard or we have a drastic drop in power then we'll worry about it . .

Also remeber that is the old tune on less boost and without nitrous.. The new setup is getting a BW372 VS the SC61 that was on it before, 11.5:1 pistons 84MM VS 10.5:1 82MM along with a bunch of other goodies .. So I doubt we'll have an issue making power up top..

Thanks for all the suggestions.. LS/VTECs are boring, done plenty of them, this is more of a challange , makes it fun

 

TQ isnt falling off from 7-8k, so if you increase the revs, HP is still building. Look at the graph, its there.

 

call Bisi, he has a few different ways to go about what your looking for.
