i will do my best.
I believe the basic pettit kit and the hymee basic kit will produce very similar performance.
you are right that the pettit kit has an a/w intercooler and the hymee is a/a. both have their own pluses and minus's.
the pettit kit is a direct pulley drive with its own dedicated belt/pulley
the hymee has a single serpentine belt system for everything--water pump, alternator and s.c.
the hymee unit uses a layshaft from the belt pulley to the other end of the s.c.(he used a different mounting design)
both have custom uim's
both use the oem coils--pettit supplies aftermarket sparkplug wires as they mount the oem coils in a different location.
pettit uses a oem computer flash and updates/modifications if wanted via the EFI which is a flash unit and ob2 data logger. it is also part of the pro tuner family.
hymee uses the protuner for its flashing/tuning.?
hymee went to "stleath' styling as even the oem engine cover can be used
pettit is "right there"!
pettit is a self lubed system
hymee is tapped into the engines oil supply.
Thats what i think I know. Hope it can be of help.

I am having a really hard time figuring out if the Hymee is worth the extra $1920.
Draggers breakdown confused me even more. lol
I will have cash in hand on the 8th so I really need to figure this out.

I bleed them again yesterday night !
much better...I am trying not to step too much oon the brakes for the first days...
Too Late : this morning an a*s H$^ùe brake just in front of me; had to stand up on my brakes, what a difference between the oem brakes !

To me also just not technical but a good reasoned answer.
On a non technical basis, Hymee s/c is a thing of beauty and has a lot of "finnished" parts with it (polished). I am sure that the extra manhours in it is most of the higher cost. I believe that another part of the additional cost is that you get a complete pro-tuner system.
I can't speek for Hymee but the BHR coils will work just fine with the Pettit s/c as will the Cobb AP.

Status is that the manufactuer is asking Cam to put in an order of 50 to reproduce, Cam has about a dozen or so genuinely interested people, but with rumors of the blower being gone for good not too many people are interested in waiting for the list to grow...

Wow, so the 1.7L is discontinued! That changes everything.
I also like the fact that Hymee uses the bigger 2.1L s/c. This means it has the potential to be a more powerful system than the Pettit.
That makes my decision much easier. Thanks guys!

ok trying to learn:
if command equivalance ratio is = 0.95 then the 11.4 af*0.95 would be the actual a/f?
could you use trims to try and estimate this?
Or do you have to visualize the table on the computer?
am I on the right line of thought or have I become psychotic again?
I dont have access to that table as I dont have a cobb, etc unit .

Jet Air and OMP distribution block go to the passenger side MAF.
Blower vent and engine oil vent go to driver side MAF.
The OMP and Jet-Air go to the MAF through the throttle body "water heater" tube.
The fuel carbon canister line (smaller "fuel line" pipe) connects to the vacuum side of the blower, right near the blower bypass valve, but it goes through the electronic "purge valve" that came off the stock intake.

thanks Kane--got ya and thats make perfect sense.
Does make you wonder--i do know that Cam's tune does not touch the factory scaling of the maf.
Vacuum lines?
I deleted my jet air and sealed it all up(actually did more than that but i had to remove the intake to do it)
omp is stock set up and draws vacuum through the maf pipe as stated
blower vent is open to air
crankcase vacuum is on the drivers side maf pipe (i have a catch can installed and a small filter inbetween catch can and the maf pipe)
purge is like said
secondary intake valve is per oem and through the vacuum cannister off the oem set up
i do not have a vdi valve.
the bypass valve vaccum is from the pettit uim.
brake booster is unchanged.
i have probably left something out.

Hi !
I have a problem !
My DSC is ALWAYS turned off !!!
I can no longer turn it on !! no DTC code (related to this ).
Does this have a matter with my new brakes ?
