Carpenter Questions

[warp9.9]

It's just been really bugging me about the 2" primary thing, I needed to math it out for myself to clearly see if it is in-fact beneficial or an ego thing.

A thought just occurred to me, the stock injectors are REALLY at the ragged edge with the 265 kit and Brute.

330cc @ 80% duty cycle

330cc * 1.2 (to find 100% duty) = 396cc

396cc * 3 = 1188cc

75 L/hr = 1250cc

soooo technically they're a tiny bit too small

Another reason why the PCV is used as it intercepts the signal to the injectors allowing max pulse width ratio to run at 100%. something tune boy or tune ecu can not change so intercept the signal after the ecu and adjust from there. I'd be curious to see the numbers using their new baffle in there pipe to see how much is lost. It seems to be even smaller then mine. I see from your numbers his torque has dropped since the first beast he built which were the 240 kits in fact thats all they had at that time.

Another great reason to use PC-V, get 20% bonus injector size

Oh my numbers, the 251/179 are pump gas not VP MR12, so they're 6% low vs what he normally publishes.

On MR12 it would have been ~190 as normally seen.

@Claviger Rob,
I tried this last year and could not find the valve and timing & duration info.
I'm curious, where did you find this?
BTW - Nice work, Amigo!
PS: I hope Paul @Paul Bryant reads and comments on this . . .

The manual has the stock cam specs, I made some educated wild ass guesses regarding cam info for the carpenter setup based on some old posts here and discussions with Bob, but you can see with stock or massive cams, the primary size doesn’t varry too much.

Sob dats allotta rithmatic.

Who makes the CES pipe?

 

[Claviger]

CES does

Home-Custom Exhaust Specialists-CES

Their will be be a set up for sale in the next few months....

I did not see any pipes for the R3?

Does it cost a lot to buy from them from the US?

 

[Claviger]

The R3 pipe is a call/email only item as it’s low volume.

It’s been a few years but they’ll talk you through your desired setup, they have a few options.

Something like 1,600 AUD, but that was three years ago I’m sure it’s priced differently now. The exchange rates a lot different these days.

Well I did order the Carpenter headers and got the ecu flashed by them. I am supposed to get the stuff on Friday. Very excited about getting them installed and seeing how much of a difference it will make. For two grand I hope so lol.
