RXtacy's slooow build up - Page 4

***TitaniumTT*** · 10-23-2013, 06:49 PM

DO IT! I need a trailer in a bad way.... and my Jeep might be down for next years event which is going to be no fun..... I'll let you know when it is next year, if Miked is planning on coming up, we'll have to get a hotel somewhere.
I was talking with Rich last night and he mentioned the NJMP gig in a few weeks.... I may blast down to hang out, we'll have to see, I doubt I'll be able to find the time but I would like to..... This event 2 years ago is when my wheel bearings EXPLODED on me

Thanks buddy. I left out what you requested

Hey John..... Lets put it this way.... the mani Mike and I built for my car is almost a carbon copy of the one we built for his.... difference beeing because of the motor mounts and firewall placement... fitting a 4" DP in my FC was a MOTHERFUCKER...... but I built a LimeRockPipe to recirc both dump tubes back into the DP.... while it wasn't fun, it took about a day to build to use it for like 20 minutes..... hopefully I can extend that this year

Yea that DP was TIGHT.

And if someone had let the limerockpipes fully cool while clamped up, we wouldn't have had to use the acetylene torch to install them

Although I must admit it was pretty cool watching them grow right up to the mating flange

So.... planning on taking this to LRP eh? LOVE IT!!! That should make up for the lack of rotaries on the track this past year

Hopefully at some point.

Few pics of the finished manifold.

It's currently 3.5" but I want to step up to 4" all the way back.

Sexy!

Nice work on the short runner manifold. I think they are the best for making power and decreasing spool time.

Gotcha, yea my plan is to do 4" all the way.

Thanks. Agreed. People doing long runner manifolds to "increase torque" amuse me. You know what makes torque down low? Getting into boost quicker

Yea I'll be getting it ceramic coated.

Yeah I always wondered too why people wouldn't want the shortest runners possible. I think mine are either the same length as yours or maybe 1/2" to an inch longer and my spool is ridiculous. It might be due to the turbo, or when I went to a slightly smaller IC, but I start boosting around 2K rpm and I hit full boost probably around 3300-3500. I wouldn't trade it for the world. It's what I've wanted for so long. My only problem is it hits so fast and so hard that I have to turn down the boost duty cycle in first, second and a little bit of third gears. But I figure that's a good problem to have lol.

RENESISFD · 10-26-2013, 05:59 AM

^ Exactly, with my setup I make 2lbs of boost at 2k RPM stock motor and ports. New motor is HBP and we shall see the change as that motor is being built.

It is a turblown tdx61 with a 1.0 a/r, super short manifold, and short IC piping, and 4" DP.

I too find it comical all the people who want long manifolds to increase torque and spool.

chibikougan · 10-26-2013, 06:22 AM

Brake boost boom!

They is confus-ed. The long runner manifold works on a naturally aspirated car. Add a turbo and the equation changes.

That's why I was curious to see how Aaron Parker's spool turned out since he has those super long runners. I don't think I ever saw his dyno sheet, although it hasn't run just right anyway.

I have an EFR 7670 with 1.05 divided, short runners and as short as piping possible to my VMIC, including keeping the pipe between the turbo and IC at 2" so there isn't any pressure loss there. I was going to go with a larger pipe right away but the guy that fabricated the manifold and other piping for me builds race cars and told me to keep that pipe small, and I figured he knew more than I did lol.

Aaron said he did research on different race teams to see what their spool was like and that's why he decided on long runners, but now I'm wondering if he was looking at one that was NA. I hope he's not disappointed but I think he might be.

And sorry for hijacking your thread, Mike lol.

You do have a turbo on the "smaller" side, but that's great spool. Definitely a good problem to have

What ECU are you running? Controlling boost via ECU or external boost controller?

Been following your build on 7club. Definitely looking forward to seeing what it'll do with the HBP

Your build was part of the inspiration for the next update

That and constantly melting coolant feed lines

Unfortunately he blew two motors in as many months. Not sure when you'll get to see some data on that setup.

Haha no worries, I like talking about rotaries almost as much as building them

RXtacy · 10-26-2013, 02:57 PM

Has anyone else encountered this? My turbo oil feed port is off center, and doesn't line up well with the fitting.
