Picked up the car today from the dyno and talked further with tuner. It looks cyl 5 is not the only one but it's worst. Cyl 7 looks as well same problem a bit.

I wonder what size springs my PRC heads will take. I'm running PRC 650s and want to swap them out to something to support a bit higher RPM. Running Ti intake, SS exhaust on a fairly mild cam (230/246 LXL/LXL). Sounds like PAC1207X might be a good upgrade.

I love threads like this because you can get solid tech in them along with the car ****.

LOL! I love your term Street able lol! Yeah I was there when Dave finished the 3D insert and installed it in your car. It was a very cool piece and crossed my mind, but the price tag put it out for me when all my factory gauges work fine. But you baller guys can swing that stuff no problem with your huge pocket books. Yeah I'm jealous lol! Your car could be impressive. but I saw I go together and while you might drive it on the street etc... Its more race car than street car lol! But a bad MF for sure! I mean everyone should have a pair of rain catcher DP's sticking out the hood!

Nice documentation They look like they might have been better off with a shim under them to get the install height down to 1.800" or less which would bump operating pressure up overall. They are probably not junk, but the new springs will give you a edge in pressure. I'd measure those also and make sure they all set up where you would want. Good job though.

Yeah thanks!! Absolutely I will measure each valve installed height as well new springs and will shim if necessary.

Originally I made back pressure measuring only to the passenger side but now due to valve issues want all the information available so welded the plug to driver side as well. At same had to turn bit cyl 7 lambda plug make some extra clearance for sensor. In plans add LTCD's for every cyl instead EGT's. And filter side pressure measuring next to turbine wheel.

I have dash in test use as well, it's temporary installed now. Just thinking if replace oem cluster..

Sorry for daft questions but what are LTCDs? I thought EGTs per cylinder should give you all the info you needed. Do to you also have O2 sensors per cylinder also?....

Yeah, lambda per each cylinder.. EGT's works slow compared CAN O2 sensor..

Tuomas, do you use GM knock sensors, or is there a better way to do it in your case (Motec)?
