I am in need of a rebuild and am trying to find someone to do a bridgeport and add the extra dowl pins to my motor. I will have all the seals purchased by the end of next week and was wanting to get some prices on the actual porting and motor work.

I have contacted Chris with Esmeril and a couple others. It seems that whenever i ask for a price or estimate the conversations just stop, no matter who i am talking to. I am not sure if there is a lack of knowing what to charge or if people are just getting to busy to answer or reply.

If anyone would know of a reputable person that could do this that i could talk to and preferably has ported a renesis ( i know there are few people out there) if they could send them my way or shoot me some info i would appreciate it. Thanks guys.

 

I know that BHR does port engines but i don't know if they do bridgeports. At least Charles always replies and is a reputable rebuilder.
Then BDC comes to my mind, and Esmeril but they didn't come back to you from what i understand.

 

Contacted BDC.... awaiting a reply from them also. I did not know that Charles has done portwork on a renesis. Obviously he is a reputable guy also. I was liking Esmeril cuz they were somewhat local also so i would not have to deal with shipping of any sorts.

 

Come on there's a much easier, much cheaper way to do this.

I found a great DIY on the Audi forum: http://audiforums.com/forum/showthread.php?t=80267

 

I am not even goin to click that link....... i am guessing its the sand into the intake thread. We all know that doesnt work on a rotarty :-)

 

ahhah very true....

Is there an engine rebuilder on the North East Coast?

 

That's true I forgot about that... the excessive spinning of the rotary creates sand cyclones and that can get dangerous for the people driving behind you...

 

There's Pettit in Florida

 

My only deal is, is that i know its relatively new to a renesis and the tolerances are quite small. Thats why i was kinda lookin into someone who knows the renesis and had portwwork on them before. Didint just want to drop it off at some local shop with a few pictures and let them have at it lol

 

Has Pettit done portwork on the rennisis before? I know they are a big name in the buisness but i always accociate thier name with superchargers.

 

With the racing season over, you may give Mazmart a try. They have a very skilled rotary engine guy that may give it a go.
There was a bridgeport thread and Brian @ BDC was giving some input. You may want to review that thread and see who was actually trying it.
I don't believe that BHR ports engines. Ray had his engine done, but the work was performed by RotaryGod as an experiment. RG isn't ready to do anymore Renesis work due to limitations in the port designs.

 

I was just answering heyarnold's request I don't know much about pettit.

Didn't BHR also work on Phil's engine?

 

I believe Ray rebuilt his engine. If any porting was done, it was just smoothing out the remains from the casting. Nothing in the way of port enlargement.

 

Ray at BHR did some port work on my 8 when I had him rebuild my engine. I think I know what his answer will be but get it from his mouth.

 

Does anyone know if there is a video up of the car that BDC did the portwork on? I found the one that esmeril did and the one from South africa. Are those the only three cars on here with a bridgeport?

 

It's not that I'm not willing to do it due to a limitation in port design. It's really a lack of time. I told Ray I'd get his done in 2 weeks and instead it took me 2 months. Admittedly his ran into issues which pushed things back but I don't want to get caught in another situation where I can't meet a deadline. It's not fair to the owner.

I am also weary of porting housings for others but not doing the whole engine build. If an issue arises it's easy to point fingers and place blame but hard to prove where the issue actually was. With Ray I knew what his future plans were and we were both very clear on what was being done and what the risks were. He was also far more understanding and patient that he probably should have been but I definitely appreciated it.

Yes I can do it. Yes I am open to performing port work on them as opposed to leaving them stock. However at this time I don't want to do any work for anyone else. I don't have the time. Brian (BDC) on the other hand can get it done pretty quickly and does some of the finest portwork I've ever seen. He goes a step farther than I do. I make it functional. He makes it functional AND pretty! Pretty doesn't make you faster and it takes longer but it does say alot about the builder. It says he has more time to devote to porting than I do!

Phish: Where are you at in DSM? I get up there every year and typically stay in Urbandale.

 

The more i hear it seems like Brian is the way to go. I will try emailing him shortly to get more info from him. He failed to reply to my most recent PM so maybe email will be a better route.

 

I do not think anyone has posted ANY actual data or numbers at all.... not even a dyno. turbo or NA

 

I will have the motor torn apart for the rebuild, i just do not want to regret later on not doing it.

 

BDC all the way. Have you seen his ports? They look like a 5 axis CNC machine made them....

Usually he's really good about getting back to people...try calling him (I think his number is on his site, if not PM me and I can give it to you)

 

Yeah, if you are having the motor torn apart anyway I understand the desire to have it ported at the same time. It's definitely not worth tearing the motor apart specifically to port, but if you are doing a rebuild and are interested in porting the motor, now is the time. You might also want to consider trying some aftermarket apex seals... if I do a rebuild I plan on trying out the Esmeril seals and getting the motor pinned. Probably overkill for my boost target, but if I ever need to do a rebuild why not?

 

So now the question is to port or not to port. I totally see charles point of view and now its jsut gettin some data on it.

I know my Girlfriend would like if i DID NOT port my car. She hates the sound clips on line that i happen to love. I hear you have been talkin to my girl a lil bit Charles ;-)

 

Already have the esmeril seals, and ordreing a full rebuild kit from atkins at the end of the week. I am also going to have the extra pins put in when ported..... if i port.

 

i would think about balancing the rotors with higher precision rather than focusing on the extra dowel pins that may or may not help! We go through fashions with engine mods so everything new basically looks cool imho... that may be the extra dowel pin's case for common applications. Better clearances and balances always help though!

 

For me to port or not to port would boil down to cost....the cost of the builder to port the irons...the shipping cost/risk involved, etc. If you can get the porting done for a reasonable price and you aren't on a tight time table I would go for it.
