the other motor and carbon fiber trim

^ that's what i saw

yea, the motor :naughty:

Thinking about building an FI block next...

If I try and boost my Iannetti ceramics, Rick E and Paul will most likely flog me if I cannot get it tuned properly. Not sure how much boost the ceramics can take, maybe 5 PSI? So, that motor on the stand is my original block that will get ported and doweled together for turbo boost.

now you are talkin'

Nemesis: what are you monitoring on those gauges?
I assume the one on the left is AFR?

looks like fuel pressure. good choice.

now start on that FI build please!! :)

haha - fuel pressure is correct. You guessed the other one.

Man cannot live too long without booooosssttt

Mazda Motorsports rates the Iannetti seals for a higher boost pressure than you will ever run in a Renesis. It's all in the quality of the tune and supporting components.

That is a weird flapping sound. Did you listen with a stethoscope to see if you can narrow it down?

Stethoscope says water pump. I wonder if the sound resonated in the hard firewall water pipe?

The first seconds the sound changes completely.

it really reminds me of a spark jump, but that would have to be a huge jump to make that much noise..

beers :beer:

BHR Ignition with 6000 miles on it, and brand new plugs for the dyno day, so even though it may sound similar, it is not a spark jump. My money is the water pump, and tonight I will drop the drive belt again to find out. Thanks for looking man!

How about 9 PSI, is that a safe bet? :dunno:

No belt - no sound

hey thats what i said!

That's interesting.

dang, this car never ceases to amaze me - I'm always working on it lately....

we're all working on our cars a lot these days.. new motors, weird issues, maintenance, etc..

the big problem for a street car is there's no guaranteeing the quality of pump gas

Paul is taking care of me on the water pump. Great company that Mazmart!

As soon as I have it installed, I am off to another dyno, with a catless midpipe. :)

Pump gas sucks - that may have been Denny's downfall also. Tune for 87 even though the pump says 91....

or spray?

crap just threw P2004 and P2503.
