A interesting Job. What are the cam specs if it's not a secret?

Going to be close, the lid is thicker than my original plan by 1/4 inch

Be interesting to see a dyno run after you get this manifold in service....

Good Luck Lee.

I would like to see an A/B comparison.

Re: Frankenplenum
 
Going to leave the lid bare...what color should I make the rest of the plenum....I know its lipstick on a pig, but...

-=Jeff=- 05-11-2015 11:22 AM
Re: Frankenplenum
 
Why not test it first, then worry about color..

LGAFF 05-11-2015 11:53 AM
Re: Frankenplenum
 
Obviously test fit is in the plan.....going on one way or another

Well, that is not what I meant..

not Test Fit.. Test it, meaning.. why make it pretty if you put on and it makes the motor run worse..

I suggest test it out for a while first before making it pretty

She is about 1/4 too tall.......will shim the hood

I am telling you I will swap you if you are going to cut the hood

Re: Frankenplenum
 
those runners look as if they were sanded smooth prior to the black PC or is the PC really thick to make it smooth?

LGAFF 05-22-2015 08:47 AM
Re: Frankenplenum
 
No black gloss really covers well...no sanding

LGAFF 05-23-2015 08:04 PM
Re: Frankenplenum
 
Definitely going to need to shim the hood....and even take 1/4 inch out of the center of the plenum cover(its 1/2 thick)

What are you looking to gain with this set-up? Looks very cool :flag:

Re: Frankenplenum
 
Hoping to see an HP increase, would take 10-15hp...I think opening the inside runners and moving the roof away from the runner will help with flow....but I have been wrong before:)

LGAFF 06-07-2015 12:54 PM
Re: Frankenplenum
 
"Frank" is up an running, need some new tires and will then do some testing

By chance I opened up the oil fill cap and my upper chain guide faceplate has come off and is floating....:censored:

When will you go on a dyno? The german racing Team did a 2nd dyno run with impressive numbers.

LGAFF 07-21-2015 11:20 PM
Re: Frankenplenum
 
Had Frank out last week.....running good....getting new Toyo Proxes TQs put on this week. Still one small oil leak(,ight be the oil sensor), but its about time to get to the dyno.

That's pretty close. I also check my KEY ON MAP signal because unless u are at sea level, your MAP won't be at 100kPa anyway.
I'm a bit skeptical like Todd but it's good to have someone like you Lee who'll test it out.

Lee,

Came out looking great. Excited to see the dyno results.

LGAFF 08-02-2015 11:45 PM
Re: Frankenplenum
 
I will be curious to see myself....could be anything from a loss in power to significant gains. Crap shoot....fingers crossed for tomorrow.

I left the Corsa system on for apples to apples test.

Next dyno test will be a 3" ....and finally a tune

-=Jeff=- 08-03-2015 11:03 AM
Re: Frankenplenum
 
What was the previous result? Prior to the plenum change?

LGAFF 08-03-2015 12:13 PM
Re: Frankenplenum
 
Win some lose some; car lost power....only interesting piece was at 7400rpm the car was only down 8hp from peak.

Frank Set Up
426hp@7100
361 ftlbs


Siamase
441hp@7100
373 ftlbs

LGAFF 08-03-2015 12:28 PM
Re: Frankenplenum

11.8 to 12.46 most of the run...

11.8-12.1 from 5100RPM to 6900
