will have flow charts later this week...

 

eagerly waiting!

was told i should see somewhere in the range of 10% increase in hp. will be hard to tell with all the other mods i am doing...

 

Bad ace. Can't wait.

 

Damn Beaphus, your build is going to be amazing. I look forward to seeing how the heads work, I'm getting bored and need something to do....damn! It's weird, that empty feeling in my stomach never goes away no matter how fast my car goes. Subscribed and good luck with your build.

 

50 odd hp from just PnP or are you increasing valve size, adding cams or raising the redline?

Any other members have experience with this? Not doubting you, because I certaintly dont have any experience with E55 heads, but 50 hp increase surprised me for just reworking the head.

Good luck with this project, should prove to be very interesting.

 

i was skeptical too. this is just what the guy who did it told me. but yes i am doing VRP cams which have very aggressive specs which i am only assuming will amplify the results. not changing the valve size or anything else. we shall see. even if it only gives me 20 hp it is worth it since my whole engine had to be rebuilt anyway...

 

thanks! uve been a big help. ill let u know

 

Do you have any other pics for the rebuild? Man this is crazy exciting!!

 

Beauphus, you should just start a main thread regarding your build. From the very start to the end, many people are very excited about your build. Just a thought.

 

no pics of the rebuild yet. headers arrive wednesday. throttle body and airbox arrive tomorrow. LSD should be monday or tuesday. hopefully pics of rebuild and video of dyno tuning on friday but might have to be early next week. we shall see...got this in the mail yesterday though...

 

I have one in the CLS section but i try to sprinkle information in the e55 section because i used to own an e55 and want to give information that benefits the E. I kinda wish the 2 section were merged because they are virtually the same car with a different chassis for the most part.

for those that want to follow along here is the link in the CLS forum...

Any chance of getting those measured before you install them? I know there are a lot of members here who are interested in that info.

 

If u have questions about the cams I recommend reaching out to mbworld member PTE (https://mbworld.org/forums/members/25963-pte.html). He is VERY knowledgeable and he designed them. Its his recipe to hand out if he chooses. Im not at liberty to disclose those specs.

 

Quaife LSD arrived on Friday!

Remember...........titanium retainers are a must Aaron.

 

thanks Bruce.

Titanium Retainers = DONE

 

Only if you plan on reving past 7K my friend. Other than that, well they are a good insurance policy, just not required.

Good luck with the build up

 

Nice! You probably wont have before and after dynos for just the PnP work though since your car is down and you are doing many mods at once right? You will have flow numbers for the heads though. There have been a few people that ventured down the port and polished heads path. It is an expensive mod and will make your car more efficient but you will lose boost unless you change the crank pulley. Good luck and I am also excited to see the final product

 

correct - u wont see a dyno for JUST the PnP. I am chnaging to the Renntech 180mm pulley. DO you think this is enough considering the other mods or should i shoot for the 190mm??

 

It depends. No matter what pulley you use, you will be making less boost because of the porting of the heads (relative to non ported heads and same pulley). Basically you will make more power at the same boost level with ported heads but your boost level should theoretically drop with the same crank pulley size. Will you still make more power with less boost, I dunno Thats the downside of being on eof the first to do something. "Enough" is a very relative term, all depends on your goals. Since there isn't alot of documented info on this mod on 55k motors it is hard to predict how much boost/power a 180mm pulley would make compared to a 190mm. From what I've read the 190mm pulley generates alot more heat than the 180mm pulley (I know the pulley doesn't generate heat, I mean it spins the sc faster and that produces heat). Either way your car should make really good power with all the mods. I would probably go 180mm pulley for now. Should be a monster!

 

Still trolling huh?

I see another FT in you and I am sure MANY members agree!

Aaron's build IS in great hands!!

 

No my friend, no troll here

I just hate to see good people place their money in areas that they do not need to

PS: I was in on the FT banning

And for the record, please show me ANY reputable engine shop that mandates titanium retainers for engines that rev below 7K. Just one please.

I took the time to find what REAL experts say, so here you go. Kind of looks like exactly I was saying


"For every gram you can reduce from the valve area (valves, retainers, keepers), you will pick up on average of 35-40 more rpm in valve control. So a 7 gram weight savings is equal to 280 additional rpm's before valve float. Good stuff"

"When you upgrade from steel to titanium valve spring retainers you
gain speed and power, because COMP Cams® titanium retainers are
lighter and stronger than steel. Additionally, our Super Lock™ titanium
design gives you confidence; no longer will you be preoccupied with
splitting a retainer and tearing up an engine when turning 10,000 rpm."

"They are virtually unbreakable and are recommended for racing and Hi-RPM street use. For street use or below 7000 RPM we recommend aluminum retainers. For racing or above 7000 RPM we recommend titanium retainers"

Hey, if money is NO object, than as I said above sure for the insurance policy. But as I said they are NOT required for a low rpm blown engine my friend.

Sorry for the OT rant guys, and Good luck with the build OP

 

This is a great build up the real thing, not just bolt-ons, Good work Beauphus.
I look forward to meeting you at the up coming GTG in Boca/Palm Beach

 

Lookin forward to it
